Goodbye, Cassini

I was only 15 years old when I saw the announcement for NASA’s upcoming exploratory mission to Saturn.  At that moment in my life I had solidified my interest (sorry, “obsession”) with spaceflight. The brief article burned in my mind with NASA’s bold assertion: this new space probe would be exploring the planet Saturn from orbit.  Saturn! No country had yet sent a spacecraft to study specifically the ringed gas giant.

On Friday, September 15th of this year, Cassini will descend into Saturn’s atmosphere after nearly 13 years in orbit.  The spacecraft was lunched in 1997 and entered orbit around Saturn in 2004.  Take a moment to think about everything that you’ve experienced for the last thirteen years.  For the entirety of that period, planetary scientists from around the world have been working to study the data returned from this far-flung space probe.

The spacecraft (which is nearly as large as a bus and is powered by a nuclear radioisotope thermoelectric  generator) has shown to us visions of a world alien to our senses.  Photographs taken by the Cassini orbiter have allowed us to see things we are incapable of viewing from earth such as the hexagonal jets streams turning about Saturn’s poles or the faintest of the rings that encircle the planet. A magnetometer onboard has measured the first record of the planet’s magnetic field. Orbits that passed the famous ring structure made it possible to determine the nature of the matter that forms them. And imagery returned of the diminutive moon Enceladus has shown what appear to be geysers of water erupting from its surface. (The tiny world was thought to be of too little mass to feature active geothermal processes).

One of the most impactful elements of the mission was the inclusion of a lander probe, know as Huygens (Named for Christiaan Huygens.)  The lander detached from the main spacecraft and entered the atmosphere of the moon Titan in 2004.  Never before had humans seen what existed below the clouds that masked the surface of the largest moon in our solar system.

Everything we know about the chemistry, atmospheric makeup, geography, and geology of Titan comes from data collected by instruments on Huygens and Cassini. Here is an entire world, alien to us, yet close enough to be similar.  We can see in images like the one above that Titan has hills and shorelines and most of it was formed by chemicals other than water. Instead, we know through Cassini that Titan experiences a hydrologic cycle that is made up of ethane, methane, and hydrocarbon rich nitrogen.

The longevity and audacity of the Cassini mission has, and will continue to have an impact on NASA and its affiliate s for decades to come.  Unlike the Voyager and Mariner missions of the 1970s, Cassini did more than a dramatic flyby of Saturn -it persisted.  The mission not only demonstrated the technological capability of deploying a separate lander, but of the extensions to the original mission profile and flexibility to change targets.  In an increasingly risk-averse aerospace culture, the Cassini team proved that bold goals can still achieve results.

There’s a certain sadness than comes naturally at the end of a space mission.  Years of labor and study come to a close, and in many cases, the actual hardware is lost to the cosmos forever.  Additionally, trends in both science funding and politics have curtailed further proposals to study Saturn and its moons.  For those who’ve dedicated their lives to the study of the outer planets, this week could be the last an American spacecraft visits Saturn in their lifetimes.  It’s justified to feel bittersweet about the successes Cassini/Huygens accomplished when political changes suggest there will be no successor.

But there is hope: Every decade, the U.S. National Research Council meets and publishes a document known as the  Planetary Decadal Survey . Participating scientists make suggestions, balance cost versus scientific return, and prioritize potential future exploratory planetary missions. the last decadal survey was conducted in 2011 and the report was published a year later.  In the 2011 survey, strong emphasis addressed the lack of knowledge concerning Europa, one of Jupiter’s icy moons.   This had impact on NASA’s decision to approve a planned orbiter probe, now known as Europa Clipper.

Saturn and it’s moons were not left out; in fact, there were seven distinct mission concepts featuring the ringed-gas giant in the 2011 survey. Listed, they are: Titan Saturn System Mission,
Saturn Atmospheric Entry Probe Trade Study, Saturn Atmospheric Entry Probe Mission Concept Study, Saturn Ring Observer Concept Study, Enceladus Flyby & Sample Return Concept Studies,
Enceladus Orbiter Concept Study, and Titan Lake Probe Concept Study. While none of these mission concepts received the priority or impetus of Europa or Mars, if offers a glimmer of hope for the researchers who wish tone day delve deeper into the study of Saturn.

For now we will have to remain satisfied with the years of data Cassini/Huygens delivered.  In days, the spacecraft will descend into Saturn itself, heated by the friction of the planet’s atmosphere.  What remains will be pulled deep into the gaseous abyss, eventually crushed by the immense gravity.  A mission is complete. Goodbye, Cassini.

Film Review: Fight for Space (2017)

“Where is your space program?”

This is the tagline that summarizes the independent documentary “Fight for Space“.  Produced and directed by Paul J. Hildebrandt, the film attempts to discern the point at which NASA deviated from the traditionally understood pathway of space exploration to the stasis the agency exists in today.

Fight for Space collects a considerable “who’s who” of spaceflight luminaries- from Apollo era astronauts to the most prominent astrophysicists in popular culture today.  Through interviews, the audience gets a glimpse of the opinions of these noted individuals. This is the film’s strength and crutch. By focusing much on the perspectives of those closest to the state of NASA in the 1960s, it emphasizes the positives of the Lunar exploration missions without explaining the scientific progress being made in space today.

Fight for Space is heavy on the nostalgia for the Project Apollo and the lunar landing missions of 1968-1972.  I say this upfront as framework in which to understand the documentary.  As the lunar landings have defined the extant which our species as travelled beyond Earth, they also remain as the benchmark for public perception of what space exploration is to be.  And in many cases, this measuring rod is wielded by space exploration advocates as well.  In Fight for Space, the viewer is introduced to a number of outspoken spaceflight advocates who adhere to this idea, and aren’t subtle in their presentation of it.

Following President Kennedy’s 1961 address at Rice University, political momentum built to surpass the Soviet Union in the development of human spaceflight.  In a simple challenge, a goal was set that drove the fledgling NASA to the surface of the Moon. When that was achieved in 1969, a few additional missions continued, until public and political support dwindled and the project was terminated.  This unparalleled event has remained so, as no further human missions beyond earth orbit have been carried out.  Fight for Space  takes the viewers back to this period, letting such gentlemen as Gene Kranz, Jim Lovell, and Story Musgrave describe the incentive for Kennedy’s challenge.

Why did NASA stop sending astronauts to the Moon?  Perhaps no other question dominates the public consciousness concerning the space program.  This documentary explores that question thoroughly, which becomes the film’s strength. From Kennedy’s brinksmanship, to Johnson’s maintenance of the legacy, and finally Nixon’s self-imposed strife, the audience is shown how the executive branch dictated space policy, from Mercury to the Space Station.  As compelling as the missions themselves, the history of NASA is populated by heroes and villains in the quest for funding.  The stories of compromises that resulted in the final Space Shuttle configuration and contemporary Orion spacecraft are both heart-breaking and hopeful tales on par with the greatest of the golden age oceanic voyages.

Space policy professionals such as Marcia Smith, Rick Tumilson, James Muncy, and John Logsdon add their takes on the fate of Apollo and what it meant for NASA throughout the film.  These interviews are the meat in this sandwich, offering nuanced perspectives on the direction of the space program from professionals who were not astronauts or engineers. Each of these speakers makes the point that, in essence, its not for a lack of technical failure that Apollo was discontinued, but a lack of political will. [We] stopped going to the Moon because [we] (Congress and the White House) chose not to.  I emphasize this is an important distinction he film makes- NASA didn’t curtail human spaceflight, the bureaucratic and partisan machinations of government did.

What this results in is less a documentary than a lament for space exploration achievements of the past.  There is no fault in the direction, cinematography, or editing in Fight for Space.  Nor is there a criticism in the message- that human spaceflight is best destiny for our species.  Where the film falters, when it does, is the emphasis that “NASA is going nowhere”.  (This message is reinforced by interviews with Robert Zubrin, Lovell, and Musgrave).  Emphasis on “destinations and timelines”, such as Kennedy’s 1961 speech, oversimplify the challenges of space exploration and hint at repeating the errors inherent to Project Apollo.  One of the best sequences in the film shows the fallacy of building disposable spacecraft that shed components via computer simulation of an airliner discarding its wings, tail, engines on a flight from Los Angles to New York.  Again later, there is a point where narration commends the Russian space agencies for relaying on sustainable technologies to support orbital access. Yet this epiphany is buried just as quickly as it is shown by over emphasizing the successes of the Saturn V rockets (Of which not one component was reusable, and which was monetarily unsustainable).

I was disappointed in how the film chose to represent the contemporary era of NASA (and it’s commercial partners) and in particular, the International Space Station.  ISS, as it’s abbreviated, has been the focus of much of the negative press aimed at NASA.  Many politicians, space advocacy pundits, and spaceflight enthusiasts tend to point toward the space station as “all that is wrong” with America’s government managed space program. This film could have made point to better share the science being conducted in orbit today, perhaps even altering the public perception of ISS.  Instead, we are left with a few minutes in the movie where random pedestrians are interviewed about the role of ISS, in which each person admits to their ignorance of it. The director rightly ascribes to NASA’s inability as a n agency to “sell” ISS to the general public, but then does the same by leaving the viewer with no answers.

Of all the “space celebrities” interviewed for the documentary, Dr. Neil deGrasse Tyson was by far the clearest in enunciating the political dance NASA has endured in it’s 50+ years.  As much as many spaceflight enthusiasts are loath to admit it, the agency cannot act independently of the legislative and executive branches of our government.  To lambaste the administrators of NASA for “lack of will and vision” is a copout.  NASA can only do what it is authorized (and funded) to do.  The film illustrates the transition period from the Space Shuttle and potential follow-on vehicle development programs Constellation and Space Launch System. Much to the credit of the director, the film does not take any partisan political slant here where too many others have before.  Many space policy advocates have pointed to the previous federal administration as crippling the space program for the cancellation of Constellation, but few diagnose correctly the ailment was lack of congressional support.  Fight for Space rightly shines the light on this controversy without falling for the easy path of choosing a political scapegoat.

My review of this movie may seem mixed, and that would be truthful from my (as yet) single viewing.  As someone who has absorbed a great deal of the media surrounding NASA and it’s contemporary space programs, I feel that this documentary missed an opportunity to tell the story of what is happening is space NOW.   Indeed, “where is your space program?”. It’s not in the 1960s, nor shouldn’t it be.  There is so much more to the progress necessary for any future explorations of Mars, for example, than shown in this film.  Overemphasis on launch vehicles is one of the most aggravating elements of space advocacy in my personal opinion.  And that is the sidestep this film does when lamenting the cancellation of the Saturn V rockets. (An educational sequence to be sure, but is that what the audience should take away from this?)

Human space exploration has always been a story of hope.  There can be a powerful, positive message in any film describing the progress of understanding our solar system.  Fight for Space doesn’t necessarily become that movie. The audience is left with hopeful statements by Dr. Tyson and Mr. Tumilson, following a sequence describing the benefits of an inspired populace. Examples included technology spinoffs, higher education participation, increased understanding of STEM principles – obvious to the space enthusiasts, and necessary for any film advocating spaceflight.  But by turning to look back on the glory of Apollo, we lose sight of where we’re going. (Or for those who interpret NASA’s current path as going nowhere, where we CAN go.)  Perhaps it would be the topic of a different documentary, but as it has been repeated consistently that the goal NASA is pursuing is human missions to Mars, I believe it would have been more effective to include the research a development taking place within NASA today as a coda, and ask “WHEN are we going?”

 

Why YOU should join the National Space Society

nsslogoblock4c_4

 

There has never been a better time to become involved in policy as a citizen.

Access to information has never been greater, and the ability of the motivated person to share a message is unprecedented.  From municipal levies to national reform, Americans benefit from active participation in public policy.  For those interested in space industry and science, the ability to promote measures of protection for research or ensure funding for programs is incomparable.

The National Space Society is America’s largest public space advocacy organization.  There are chapters in every state, and in many cases, one in each metropolitan center.  NSS is a 501(c)(3) nonprofit organization, and therefore is not an entrepreneurial venture. Under NSS’ 501(h) regulations, NSS is allowed to conduct grassroots lobbying, which permits a limited amount of activity aimed at influencing U.S. legislation.

Unlike a number of other space-oriented associations, the NSS takes a broader approach to the various topics encompassed by the space industry.  While some organizations focus their energies to promote aerospace engineering, Martian colonization, or satellite technology, NSS looks to bring together all proponents looking to further space exploration and utilization. The advent of commercial space enterprises has provided NSS with a boon for promoting nascent launch opportunities.

NSS was formed in 1987 after two previously established space advocacy groups, the L5 Society and National Space  Institute, were merged. While the initial intent of the society was aimed at promoting space settlement, it has evolved into something more. The organization states it’s mission to be: “to promote social, economic, technological, and political change in order to expand civilization beyond Earth, to settle space and to use the resulting resources to build a hopeful and prosperous future for humanity.”  The vision of NSS is: “People living and working in thriving communities beyond the Earth, and the use of the vast resources of space for the dramatic betterment of humanity.”  The society also publishes a monthly periodical, Ad Astra, which members may contribute to.

Each May, NSS hosts one of the largest space-oriented conferences:  The International Space Development Conference, or ISDC. As stated on the NSS website, “The annual conference of the NSS, bringing together NSS leaders and members with leading managers, engineers, scientists, educators, and businessmen from civilian, military, commercial, entrepreneurial, and grassroots advocacy space sectors”. For space professionals and enthusiasts, ISDC offers an opportunity to learn from and network with those who practice in the industry.

ISDC 2017 will be held in St. louis, Missouri, May 25-29.  Organized by the St. Louis Space Frontier (the local NSS chapter), this year’s event is conveniently located in the Central United States, within minutes of Lambert Field.  While living in St. Louis last year, I had the privilege to take part in the planning process for the conference.  What I found most remarkable about this was that this enormous challenge, all of the logistics and fundraising, was being conducted by space enthusiasts like myself.  Professionals in their fields for sure, but not one of the individuals involved was being compensated for this effort.  Instead, these were dedicated volunteers, working every week to ensure that this event is organized thoroughly.

Members of NSS are encouraged to provide input regarding their opinions and interests for the exploration and/or utilization of space.  Few advocacy organizations provide opportunities for their membership to shape policy to the extent NSS does.  From regular surveys to gauge interest in contemporary NASA and commercial space concepts to inviting members to participate in visits to the legislature in Washington DC, NSS desires proactive involvement.  The space message boards, letter-to-the-editor, and social media sites are inundated with the opinions of space enthusiasts.  So many people with so many ideas and thoughts on the direction of national space policy- but few who make any effort to effect that policy.

Like any grassroots initiative, the National Space Society’s efforts to effect policy by advocating STEM initiatives, supporting tech development, and contributing to legislative process requires proactive participation.  It is never enough to cynically call for change without offering to be an engine for said change.  NSS Chapters lead local efforts to promote space policy, both regionally and nationally. By taking advantage of this organizational framework, the membership is given a voice.  And while citizen petitions, legislative blitzes, or other forms of advocacy may not change the direction of congressionally derived authorizations, it certainly won’t without trying.

Wherever you are, there are ways to take part in the efforts to explore and utilize space.  I encourage you to follow the links below and read about the NSS.  Decide for yourself if this is an organization that you would like to take part in.  Why not be a participant instead of an observer?

HERA X: Looking for Public Outreach support

300px-Human_Research_Program_2012_(logo)

In my effort to share the story of human spaceflight (Including the various federal and commercial programs as well as my own endeavors), I would like to find ways to share my upcoming participation in NASA’s HERA analog study.

If you would like to follow the details of the simulated mission, the crew and I will be posting on Twitter to this account: @HERA_Crew_X

From April 19th through May 2nd, the other crew members and I will be training on the Johnson Space Center campus in Houston, Texas.  Each of us will be assigned a role on the crew.  Two of the selected participants will train as Mission Specialists, another will play the role of Flight Engineer, and one will be responsible as Mission Commander. During training, we will learn the tasks associated with our respective roles.

I will continue to post to this blog until the start of the mission study, and follow up afterward with more after the flight profile is completed.

If you have a webpage, write a blog, host a space/science/STEM social media account (or know someone who does) and would like to know more about the HERA X mission, feel free to contact me and I will do my best to answer your questions.  I would love to share this experience with a wider audience.

HERA Crew 10 Mission Patch

HERA Crew 10 Patch (Design by Oscar Mathews)

HERA Crew 10 Patch (Design by Oscar Mathews)

As with every mission that preceded it, Human Exploration Research Analog (HERA) mission 10 will have its own unique patch.  It will be worn by the 4 crew members, adorn equipment and apparel, and one day hang alongside the previous mission’s symbols on a wall at Johnson Space Center.

The patch design reflects the various aspects of the HERA campaign. This particular missions simulation is C3M2- or, “campaign three, mission two”.  Counting the total number of HERA crews that have used the analog habitat module, ours will be number ten.  Hence the big Roman numeral “X”.  The X has another significance this particular study will take place during the 50th anniversary of Gemini 10, which also used the large Roman numeral 10 in the mission patch design.

Each of the crew members names appear, as do 4 stars representing the number of crew.  Occupying the foreground is the asteroid Geographos, an actual asteroid found near Earth, one that actually crosses our planet’s orbit, and the simulated target for this mission. (Conveniently closer than the asteroids found orbiting the sun in the asteroid belt).  Earth is to the right, eclipsed behind the asteroid representing both the origin and final destination of the spaceflight. Mars is there too- always in the background, on the horizon of all NASA’s human spaceflight projects.

Finally, you can see our spacecraft or a representation of what a craft might look like if one were to attempt a human mission to a nearby asteroid.  The design we chose to use was NASA’s “Nautilus X“, a conceptual deep-space craft for beyond Earth orbit  (BEO) exploration.  Although such a vehicle is likely decades away from actually transporting astronauts anywhere, it follows the existing engineering principles necessary for such a journey.

I’m really looking forward to wearing this patch on my uniform!

I Return to (Simulated) Space

Continuing my goals of playing a role in human spaceflight, I recently applied to and was accepted as a participant in the Human Exploration Research Analog (HERA) campaign.

HERA is a “high-fidelity research venue for scientists to use in addressing risks and gaps associated with human performance during spaceflight.” (according to NASA’s website.) It is a project operated by NASA’s Human Research Program, or HRP, located at Johnson Space Center in Houston, Texas.

Like my experience in the HI-SEAS analog (You can read my post about that HERE), I will be serving as a subject for NASA’s investigation into mitigating the risks of future space missions.  As a “stand-in” for an astronaut, I will be simulating the duties and tasks necessary to conduct a long-duration spaceflight.  Whereas in HI-SEAS the mission was one of Martian exploration, this time I will be simulating the launch and flight to a nearby asteroid.

After a several decades of learning to live and operate in Low Earth Orbit (LEO) using the Skylab, Space Shuttle, and International Space Station, NASA is beginning to plan for deep space exploration missions again.  There are a number of mission concepts and targets proposed, with all choices eventually leading up to human landings on the planet Mars.  But before a rocket carrying astronauts can reach the red planet a number of milestones need to met.

One of the precursor missions being developed is rendezvous and exploration of an asteroid.  Either by direct observation and sampling, or retrieval and sampling from a safer lunar orbit, it promises to be one of the most ambitious human spaceflight missions ever undertaken.  Such a mission would provide NASA an operational test of the techniques and technologies required for the much riskier Martian exploration flights, just as Gemini preceded the Apollo Lunar missions.  (For more about the proposed Asteroid Retrieval Mission, check out NASA’s page)

The HERA study profile will be that of a human spaceflight mission from launch to recovery, featuring a rendezvous and virtual EVAs to collect samples from the target asteroid.  To do this, myself and three other crew members will train for and conduct a 30 day simulation.  This will provide the HRP researchers with an opportunity to record and evaluate our ability to complete all of the duties required of astronauts during that period.

Similar to HI-SEAS, I will be the subject of a multitude of human factors experiments.  Participating institutions will incorporate ways to evaluate our physical and mental health, our cognitive skills, problem solving, time management, nutritional balance, and team building.  Feedback from surveys (and video cameras placed throughout the HERA hab structure) will be the primary methods of collecting the data from the crew/subjects.

The HERA project us centered around a versatile habitat module structure that has been used in several NASA programs.   Initially devised as an engineering test article, the 3 story structure was known as the “Deep Space Habitat” or DSH.  As a generic design not specific to any particular mission, it has been used as a static and mobile research platform.  In 2011, the whole unit was trucked to Arizona and assembled to take part in the Desert RATS (Desert Research and Technology Studies) analog.  Today the DSH serves as the core module of the HERA project and is located on the campus of Johnson Space Center.

HERA DSH Module (NASA)

HERA DSH Module (NASA)

As you can see in the diagram above, it is not a large living space. The interior is designed to reflect the cylindrical shape of space structures launched from Earth (as each component of ISS was).  It features a laboratory, storage, crew quarters, galley, and fitness equipment.  Attached to the main DSH are hygiene and airlock modules. Windows are replaced with video screens that will play vistas appropriate for each phase of the mission profile. (The depiction above doesn’t show the 2nd or 3rd stories, in what is known as the “Badger X-ploration Loft). Like a real spacecraft, there is no unnecessary space.  Astronauts are creative with small living spaces, and I suppose I will learning to cope soon too.

My return to (simulated) space is just a month away.  I will post more about my experience here, so check back for updates. During the study however, I will be not be able to access social media, so you’ll need to be patient. There will also be restrictions as to what I can share because of the nature of the study, but I will do my best to answer any questions that you have. Thank you for following along on my journey!

Commercial Spaceflight Training: A New Series!

PhotoGrid_1456279548768

I’d like to share with you my journey.  It’s the physical manifestation of my aspirations.  I’m going to document my progress as I complete milestones on the path of commercial spaceflight training.

(I will post my disclaimer now: I will in no way refer to myself as an astronaut, nor an astronaut candidate, nor make any assumptions or predictions concerning my competitiveness to ever be selected for a flight.)

What I will do is share my experience as I work through the various practical aspects of spaceflight training.  Each post in this series will focus on a specific skill or event required for human spaceflight.  From flight training to microgravity simulation, I will document my accomplishments and discuss how they pertain to preparing an astronaut for space.

My goal is to inform and entertain.  And maybe, if I do this well, I will be lucky enough to inspire someone too.  I will make no arguments suggesting commercial astronautics is superior or inferior to federal programs, nor extol one spacecraft manufacturer over another.  I will, however, be an advocate for the potential of commercial spaceflight.  This series will focus on the commercial space industry, not NASA. That is not to say I won’t reference NASA’s astronaut training – how could I not?  Expect though that my posts will discuss training specifically addressing commercial suborbital and orbital projects.

Please follow along and share this at your leisure.  I will post to this series on a semi-regular basis, or as often as I have the opportunity to complete another milestone.  I do this not because it is easy, but because it is hard – to keep a schedule!

NASA Astronaut Application: Goals, Expectations, and Reality

nasa_astronaut_job_-100625886-primary_idge

This last Monday, December 14th 2015, the National Aeronautics and Space Administration, better known as NASA, began accepting applications for the Astronaut Corps. The link can be found HERE

Unlike the period in which NASA operated the space shuttle and the U.S. government regularly recruited new astronauts, the post shuttle period has seen a diminished requirement for new applicants and flyable candidates.  The most recent opportunity to apply to be an astronaut was announced in 2011, and in 2013, just 8 individuals were chosen from a pool of 6,372 applicants.

My interest in spaceflight began early- But I I’m not going to rehash a story so many others have stated before. Instead, I will say that I had many other interests too, some of which were more achievable in the near-term, which ultimately became the path I followed.

It is interesting to have become involved enough in space community to know more than a few highly competitive individuals who will be submitting application to NASA this round. One those who applied in 2011 and made it to the interview portion of the process was Brian Shiro, a geophysicist working for NOAA. (read his blog here) He has written several posts documenting his experience, as well as recent article in Forbes about the recent call for applications.

In his article, Shiro states a list of observations about he NASA astronaut selection process. Number two on the list is “set realistic expectations”.  We all have a plan for ourselves, a series of accomplishments we hope to achieve in our lifetimes. We set these expectations – and if we’re focused enough, we can achieve them.  I’ve always held myself to a high standard, competitively focused and dedicated to my goals. But along the way, life happens, and managing my expectations has been an often bitter aftertaste to the reality of events.

Unfortunately, I made a choice in my past to expedite my undergraduate education and received my BA before heading to flight school with the Air Force. That degree, a Bachelor of Arts in Geography, provided me with a background in cartography, culture, and geopolitical affairs that has aided me every day as an officer in the Armed Forces.  I made a decision then to ensure I wouldn’t miss the opportunity to fly as a military aviator. Unfortunately, the degree I earned is not one sought by NASA for applicants to the Astronaut Corps.

While I’m disappointed, I understand the limitations indicated in the application. I do wish there was a recourse- some allowance for comparable experience or skillset. But that is not the case.

Rather than see this as the end of a dream, I choose to see this as the affirming of my belief in the emerging commercial spaceflight opportunities.

For anyone who knows me well or follows this blog, you know that not only am I an advocate for the commercial spaceflight industry, but that I have been working diligently to prepare myself to work in that sector.  From my graduate studies to my flying experience and more recently practical training courses, I am attempting to build a foundation of applicable achievements that can be utilized in commercial spaceflight.

screenshot221

While it is true that any market for commercial astronauts is still in the future, and that any such men and women won’t be part of NASA’s missions to Mars, the cornerstone of that industry is being made possible today.  From CubeSats to commercial space stations, new space enterprises other than those operated by federal institutions are being launched all the time.  NASA may soon become just one of many pathways to becoming an astronaut.

That is not to say the commercial path will be easier- the existing commercial spaceflight companies have had their pick of former NASA astronauts who’ve left the agency in recent years, following the retirement of the space shuttle. These men and women will set a high standard for the potential applicants that follow.  NASA’s astronaut corps is still a rather small collection of individuals, however, and it can’t sustain an emerging industry alone. Even pessimistic assumptions imply that these new space companies will need to employ more commercial payload specialists and pilots than are currently working for America’s space agency.

Despite the limitations of my education to date, I’ve sought opportunities to demonstrate my talents to commercial spaceflight industry wherever I can.  From analog simulations to training as a candidate for suborbital payload operation, I look for ways to add new skills and increase my knowledge in the subjects sought by NASA for the astronaut corps. I read informative books and papers on a wide spectrum of subjects related to aerospace and astronautics. When my schedule allows, I attend conferences and summits in order to meet with and network professionals in the industry. And I write about my experiences in order to help others learn about these opportunities as well.  Every decision I make is one to better myself, and better my chance at being selected to take part in future spaceflight projects.

I won’t be submitting an application to be astronaut with NASA this round. Maybe sometime in the future, my accumulated education and experience will meet the requirements laid out by the space agency. For now, I will continue to improve myself and work toward helping to a build a future where there is more than one pathway to the stars.

Film Review: The Martian

maxresdefault

Every now and then space geeks are treated to a great, scientifically feasible science-fiction film.  I am happy to report that The Martian, a film adaption of the novel by the same title, is one of those films.

For those of you who haven’t read the book by author Andy Weir, go do so. In fact, you should go do that now so you can watch the film when it’s available in theaters. Really, go do it.

The Martian is a simple premise: Sometime in the near future, on the third human exploration mission to the planet Mars, a martian dust storm forces the crew to evacuate and abort the mission. Launching from the surface of the storm battered planet, they escape, leaving behind one of the crew whom they believe is killed in the attempt to reach the spacecraft.  Except he doesn’t die.

Instead, fictional astronaut and reluctant protagonist of the drama Mark Watney (played by deftly by Matt Damon) is marooned alone, very much alive, on the surface of Mars.  Faced with incomparable desolation and a meager collection of leftover equipment, Watney is forced to adapt in order to survive before a rescue mission can be launched years later.

Much of the angst fans of the book will center on the next 2 hours of the film: does it portray the science (and engineering) correctly?  Of course the answer is yes AND no. For obvious reasons, there are simply some aspects of interplanetary life that just cannot be replicated on Earth. (Or effectively in CGI, for that matter.) For example Mars has only 38 % percent of the gravity found on Earth.  The film does it’s best to diminish the impediment of Earth’s 1G, but there is just so much that can be done here on our orbital rock. Wisely, director Ridley Scott didn’t attempt to force unnecessary and poorly simulated Martian gravity into the film.

Our astronaut hero is left on Mars with but a few months ration remaining in the habitat module he makes home.  Ingeniously, he endeavors to grow potatoes from some of the few remaining examples cached in the crew’s stores. Now, when he pours raw martian regolith (as non-organic soil on extraterrestrial planets is called), I cringed.  The actual surface of Mars, besides being rich in oxidized elements, has been found to contain perchlorates– an ammonium-based substance toxic to most lifeforms, including humans. Astronauts living on Mars would be constantly working to mitigate the exposure to these chemicals. Disregarding this, the premise of growing crops to supplement future Martian explorer’s diets is a well established concept. Even today, research into growing foodstuffs on Mars is a full-time occupation for some scientists.

I want to point out I’m not a scientist- I cannot vouch for the veracity of every aspect of the film’s scientific accuracy. (Although I have taken part in a long-duration Mars Mission Simulation)  There are some elements in the film which will likely leave some more literal viewers aghast.  I’m not one of those viewers- I can enjoy the film for it’s entertainment value alone.  Instead, space geeks should rejoice that this story remains true to the novel in almost every respect.

Space enthusiasts and aficionados will be excited to see the array of space exploration technology seen in the film. Habitat module? Remarkably similar to proposed NASA configurations. Mars rover? Again- nearly straight from the pages of industry’s designs. Even the spacesuit- which is considerably more form-fitting than contemporary EVA suits being tested BY NASA- has a basis in reality. (The Dava Newman bio-suit) Even as I typed this review, NASA unveiled a design concept for a Mars Ascent Vehicle, or “MAV”, just tlike the one that plays a key role in the plot of The Martian.

It can be said the real star of this film is Mars itself. There have been many depictions of the red planet in movies, some more accurate than others, and some downright laughable.  Perhaps because the surface of Mars is slowly becoming a part of the collective consciousness through the images returned from the rovers now exploring its geology, it takes more than just a red filter and matte frames of Monument Valley to adequately portray the planet in a movie.  The Martian doesn’t falter in this element. Wide alluvial plains, windswept hills, dust devils- even the incomparable Tharsis volcanoes make an appearance in the film.  (Some of the topography brought back memories of flying over the Sahara in Southern Algeria from my time in the service)

Perhaps the major sticking point in the science shown in the movie is very dust storm that strands poor Watney in the first minutes of the motion picture.  Mars does endure massive dust storms that envelope entire hemispheres for months at a time- but with the average density of the atmosphere being close to just 1% of that found on Earth, the devastating chaos featured in The Martian is an exaggeration of tremendous magnitudes. There is an enlightening article featured at Space.com by Elizabeth Howell that investigates this issue in detail- ‘The Martian’ Dust Storm Would Actually Be a Breeze. To read what NASA has to say about the dangers of Martian dust storms, click HERE.

The film is also limited in another dimension that just cannot be experienced in the same fashion as the novel: time.  The tedious efforts to farm, construct makeshift repairs, and simply wait was an aspect of the book that had a discernible impact in literary form. But constrained by the period in which a feature film can run, Watney’s sentence on Mars seems much too quick. The sequence depicting his cross-country road trip to seek out the defunct Pathfinder lander is an example. However, one manner in which the film succeeds in this conundrum is the visual degradation Watney experiences over the course of the story.  When we first see Damon on screen, he is a muscled movie star. By the time his character is preparing for his desperate rescue, he appears, gaunt, malnourished, and broken.  That gradual slide toward doom plays well in the film.

Besides our abandoned hero, The Martian also features a diverse cast of supporting characters that add to the whole of the odyssey.  This is a place where the film succeeds- adding a textured backdrop to Watney’s arc.  Taking place mostly at either the Johnson Space Center (JSC) in Houston and Jet Propulsion Laboratory (JPL) in California, these sequences of the film at first seem jarring- almost TOO much contrast from the panorama of Martian topography. But as the audience comes to know the characters, they become more and more essential to the overall story.

The crew of the Ares spacecraft is led by Commander Lewis, played by a guilt-ridden Jessica Chastain. Her crew is made up of Rick Martinez (Michael Pena), Beth Johanssen (Kate Mara), Chris Beck (Sebastian Stan),  and Alex Vogel (Askel Hennie, who seems a ringer for real-life astronaut Luca Parmitano).  In many ways, the Ares crew has even fewer resources available to them to effect Watney’s rescue than he does himself. With just a docking hatch, a spacesuit, and some orbital velocity, they ensure the story happens. Personally, I’d have liked to have seen more character development of the crew- but the film reflects the book in this regard neatly.  But for what the Ares sequences lack in-depth, they make up for in grandeur on the screen. (The interior of the spacecraft seems almost laboratory-clean, at least in comparison to photographs of the interior of the International Space Station)

More impact comes through in the scenes taking place on Earth.  The audience is treated to the politics of mission management at JSC as well as the technical trouble-shooting of the engineers at JPL.  It is through the actions of the mission directors and staff that we see how the world reacts to the discovery that astronaut Watney is alive, and the frustration of being unable to devise a way to reach him as quickly as necessary.

A very serious Jeff Daniels plays “the director of NASA” (the actual title is “Administrator“), shown mostly presenting press conferences and sparring over rescue plans with flight directors Vincent Kapoor (Chiwetal Ejiofor) and Mitch Henderson (Sean Bean).  Circling around them is an array of supporting characters whose roles are to enable the solution that help to rescue Watney.  I was pleasantly surprised how well the scenes featuring the Chinese space agency fit into the overall film, considering it essentially introduces a whole new plot arc two-thirds of the way into the story.

It has been pointed out that the scenes depicting events at the Mission Control Center (MCC) and other building at JSC were NOT actually filmed there- no government facilities look that nice!  One can only assume that in future depicted in the film, NASA was appropriated a great deal more funding than it receives currently!

The Ares’ return to Martian orbit and the “convertible rocket” rescue sequence is simply incredible on a massive movie screen.  The dance of centripetal motion as the ad-hoc rendezvous unfolds is better seen than read- an advantage the movie has over the novel. Desperate Extra-Vehicular Excursions (EVAs) are a staple of contemporary science fiction films, but few have so earnestly walked through the physics necessary like The Martian does.

Perhaps because it contrasts so much with recent space-themed dramas Gravity and Interstellar, The Martian stands apart by retaining a levity between the characters and the story that never allows the audience to feel despair.  Even at its darkest moments, the movie never twists the knife even when it could- (The scene where a catastrophic decompression of Watney’s habitat module comes to mind).  A well executed incorporation of Commander Lewis’ disco music collection plays throughout the movie, conveying in some regards the humanity that might otherwise have been lost by succumbing to an overwrought orchestral score.

There is an important addition the movie that wasn’t in Weir’s novel.  The film’s coda sequence is perhaps one of the more touching portions of the whole story, and a welcome extra.  In talking to others who’ve read the book, many are struck by the abrupt ending.  The director wisely included one more chapter to Watney’s journey for this interpretation of the story. Purists may find fault in this, but I really do think it adds to this interpretation of Weir’s novel.  I won’t spoil it here, however.  You just need to stay in your seat a few moments longer when the credits begin to play.

So, is the film any good? My answer is YES. I’ll even say it’s worth the $12 to see it in 3D or on an IMAX screen, if you have the chance.  It’s not every day we are treated to a quality science fiction film with some real science in it. Treat yourself this week and go see The Martian.

By the way, I hope you enjoy disco music…

 

Opinion: It’s Not About Being First

mars-astronaut

I’m about to say something that seems at odds with the space community-

It’s not about being first.

 

There is a curious preoccupation with people associated with space exploration and human spaceflight.  That’s the idea of “being first”. First in space, first to orbit, first on the Moon.  First of a gender or ethnicity. First to do “X’.

The media feed off the notion of “first”.  It’s headline ready, easy to report, and doesn’t require any investigation.  Public attentions span being what it is, the notion of “first” fits easily into a sound-byte and sates the Nationalist agenda so many would-be leaders feel necessary to to trumpet.

That said, I don’t mean to imply there is no merit in the accomplishments of the pioneers.  Gagarin and Armstrong will forever be enshrined on the podium of human history.  Nothing can or should diminish the struggle of the minorities who overcome injustices to reach orbit.  Every first launch of a new type of spacecraft is reason for celebration.

But “being first” is is only an achievement if you’re in a race.  If the goal of human spaceflight is making a sustained, operational industry and exploration campaign, then we (as space advocates and popularizers) should be making an effort to applaud the second and third and fourth time something in space is accomplished.  Because it is only after something is repeated that it becomes part the normalcy we hope to achieve.

If we are to tell the story of space exploration, to promote it, to build it properly in the public consciousness, then we need to congratulate the seventeenth mission of any program as much as the first.  Because it wasn’t  Amundsen or Scott that made it possible to people to live and work in Antarctica, it was the establishment of permanent research stations like McMurdo.

There is sort of a trend happening with some aspiring public figures presumptuously announcing their intent to be “the first person on Mars”.  Perhaps this is fueled by the ability to garner attention through social media, or maybe it’s perpetuated by an element of journalism that thrives on bold proclamations.  It’s an unpopular opinion, but I think these premature announcements are , if not unrealistic, then at least distracting.  I admire the setting of goals and the efforts people will go to achieve them, any message celebrating the necessity of self-motivation.

The journey to Mars will be the summation of countless untold struggles, careers, studies, investigations, simulations, campaigns, but most important, the unified cooperation of many people working toward that goal.  It is not, nor should it ever, be the story of one individual. Rather than ride on the nebulous virtue of “being first”, I argue that those who wish to popularize attention to human spaceflight instead devote energy to what is necessary to make the journey possible at all.

Spaceflight may never be routine or operational as so many have hoped, but that is the goal we who promote it should be working to achieve. The story of human space exploration should’t be watered down to who was first to be there.  It must be more than a headline; it must the story of us all.

So here’s to the crew and mission support of the 17th Mission to Mars- you all the one’s who are going to make the future possible.
