HERA XVI (C4M4) Underway


NASA’s HERA XVI Crew. Mission dates are Feb. 3 though March 19, 2018.

The sixteenth Human Research Exploration Analog (HERA) crew entered the three-story science habitat on Friday evening, Feb. 2, for another 45-day mission.

The HERA XVI crew is made up of two men and two women, selected from the Johnson Space Center Test Subject Screening (TSS) pool. The crew member selection process is based on a number of criteria, including criteria similar to what is used for astronaut selection. The four HERA explorers are:

  • Kent Kalogera
  • Jennifer Yen
  • Erin Hayward
  • Gregory Sachs

The crew are going on a simulated journey to an asteroid. They will fly their simulated exploration vehicle around the asteroid once they arrive, conducting several site surveys before two of the crew members will participate in a series of virtual reality spacewalks.

This mission ends March 19.

The second 45-day Human Exploration Research Analog (HERA) mission began on Saturday, Aug. 5 in Building 220, with an ingress the evening before. The four-member crew are Richard Addante, Paul Haugen, Shelley Cazares and Reinhold Povilaitis.

This mission will focus on the effects of sleep deprivation and ways to mitigate these effects, along with several other mission objectives. For details please visit the research tile of the HERA website. Check back to this site for crew photos and to follow the mission clock.

HERA 14 will end on Sept. 18 and will be followed by two more missions for this campaign.

Goodbye HERA, Hello Sleep: NASA’s HERA XIII Crew Returns Home to Slumber

After 45 days in NASA’s Human Exploration Research Analog (HERA), the four-man crew can hardly hold their eyes open. This mission was the first of its kind to last 45 days, as well as incorporate sleep reduction for research purposes.

“The sleep deprivation was really difficult,” said, James Titus, HERA crew member. “It really hindered our normalcy. We are used to working and living our lives at a higher level. During this mission the sleep reduction, the no-nap rule and limited caffeine – went hand in hand to really slow us down,” he said.

HERA is one of several ground-based analogs used by NASA’s Human Research Program (HRP) to research ways to help astronauts move from lower-Earth orbit to deep space explorations. A spaceflight analog is a situation on Earth that produces physical and mental effects on the body similar to those experienced in space. Participants are volunteers that must pass a physical and psychological assessment to qualify.

During this thirteenth HERA mission, crew members went through many of the motions of a real deep space mission without ever actually leaving the Johnson Space Center. This was the fourth in a series of studies, called campaigns, with progressively longer simulated mission lengths. In this campaign, this was the first of four 45-day simulated missions. Previous campaigns studied seven-day, 14-day, and 30-day missions. Longer mission lengths allow for more research studies and more data points relevant to longer duration spaceflight missions.

Several research studies utilize a limited sleep protocol for the four missions of Campaign 4. During Mission 1, crewmembers were allowed to sleep five hours per night, five days per week with a recovery period of two days where they could sleep eight hours each night. No naps and limited caffeine are included in this protocol.

This practice allows researchers to test the use of habitat lighting as a method of combating crewmember fatigue. It also allows for the evaluation of the usability of bio-mathematical models to predict crewmember fatigue. Team cohesion, performance, and interpersonal relationships are also tested under these conditions.

Despite the no siesta rule, the crew took their mission tasks seriously. As with past crews, they particularly enjoyed the extravehicular activity (EVA) on an asteroid conducted with virtual reality technology. “It was fun learning to maneuver in three dimensions, and going through the decompression protocol just like a real astronaut would. It was fascinating to me,” said Timothy Evans, HERA crew member.

Not only are the HERA crews isolated from the outside world, they must unplug during their mission. “It was really a little bit disorienting,” said Mark Settles, HERA crew member. “You get in this mode of addressing electronic communications on a daily basis. It was like stepping back 20 years by having a reduced level of constant input of demands on your time from electronic communication.”

This was a rather competitive group. One of their tasks was to use the robotic arm to grab a transport vehicle while dealing with sleep deprivation. They had 12 chances to do so and were given a score on their efforts. “The score was very important to all of us. We’d strive to get better. The ROBoT [Robotic On-Board Trainer] and cognition had a level of inter-competiveness with us,” said John Kennard, HERA crew member.

When asked their favorite thing to do while on the mission, there was a consensus: Sleep. They also enjoyed playing board games and watching movies together while not working on mission tasks. Upon splashdown at the end of the simulated mission, they planned to call their families and grab some greasy, salty fast food. But soon afterward, they all planned on catching some Zs!

Mission 2 of Campaign 4 will begin on Aug. 5. The Test Subject Screening group is accepting curriculum vitaes (CV) for healthy, non-smoking volunteers, ages 30 to 55 for future missions. Volunteers will be compensated and must pass a physical and psychological assessment to qualify. Volunteers wishing to become test subjects should e-mail their CV to jsc-hera@mail.nasa.gov or call 281-212-1492.

HERA 11 patch inspired by Apollo 11 patch

The 47th anniversary of Apollo 11 takes place during the Human Exploration Mission Analog (HERA) Mission 11. The Apollo 11 mission left the first human footprints on the moon. HERA 11 takes us one small step closer to making footprints on Mars.

This historic event was not lost on the HERA 11 crew. In designing their mission patch, they drew strong parallels with the Apollo 11 mission patch. They used the symbolism of Apollo 11 to reflect the role of the HERA in advancing human exploration while recognizing the contributions of prior programs on our journey to Mars.


HERA Mission XI is Underway; Look Inside the Habitat

Look inside the habitat that four people will live in for 30 days!

The Human Exploration Research Analog (HERA) Mission 11 crew began their 30-day mission on July 11. HERA is one of several analogs used by the Human Research Program to research ways to help NASA astronauts move from lower-Earth orbit to deep space exploration. A spaceflight analog is a situation on Earth that produces physical and mental effects on the body similar to those experienced in space. During the 11th HERA mission, crew members will go through all the motions of a real deep space mission without ever actually leaving JSC’s Building 220.
