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.
Astronauts collecting samples from an asteroid
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.

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!
