Welcome Home HERA Mission XVII!

With the Human Exploration Research Analog (HERA) habitat, we complete studies to prepare us for exploration to asteroids, Mars, and the Moon… here on Earth! The studies are called analogs, and they simulate space missions to study how different aspects of deep space affect humans. During a HERA mission, the crew (i.e., the research participants) live and work very much as astronauts do, with minimal contact with anyone other than Mission Control for 45 days.

The most recent study, Mission XVII, just “returned to Earth” on June 18. (i.e., the participants egressed, or exited the habitat at our Johnson Space Center in Houston after their 45-day study.) We talked with the crew, Ellie, Will, Chi, and Michael, about the experience. Here are some highlights!

Why did you decide to participate in HERA Mission XVII?

“My master’s is in human factors,” said Chi, who studies the interaction between humans and other systems at Embry-Riddle Aeronautical University. “I figured this would be a cool way to study the other side of the table and actually participate in an analog.” For Michael, who holds a PhD in aerospace engineering and researches immunology and radio biology, it was an opportunity to experience life as an astronaut doing science in space. “I’ve flown [experiments] on the space station and shuttle,” he said. “Now I wanted to see the other side.” For Will, a geosciences PhD, it provided an opportunity to contribute to space exploration and neuroscience, which he considers two of the biggest fields with the most potential in science. “Here, we have this project that is the perfect intersection of those two things,” he said. And Ellie, a pilot in the Air Force, learned about HERA while working on her master’s thesis on Earth and space analogs and how to improve them for deep-space studies. “A lot of my interests are similar to Chi’s,” she said. “Human factors and physiological aspects are things that I find very fascinating.”

NASA missions all have patches, and HERA Mission XVII is no different. Did you get to design your patch?

HERA Mission VXII patch, which reads “May the Force be with you” in Latin and features Star Wars iconography. It’s a reference to the mission’s start date, May 4th aka Star Wars Day!

“We did!” They said …with a little the help from Michael’s brother, who is a designer. He drew several different designs based on the crew’s ideas. They picked one and worked together on tweaks. “We knew we were going [inside the habitat] on May Fourth,” Michael said. “We knew it would be Star Wars Day. So we did a Star Wars theme.” The patch had to come together fairly quickly though, since a Star Wars Day “launch” wasn’t the initial plan. “We were supposed to start two weeks earlier,” Ellie said. “It just so happened the new start date was May the Fourth!” Along with the Star Wars imagery, the patch includes a hurricane symbol, to pay tribute to hurricane Harvey which caused a previous crew to end their mission early, and an image of the HERA habitat. Will joked that designing the patch was “our first team task.”

How much free time did you have and what did you do with it?

“It was a decent amount,” Michael said. “I could have used more on the harder days, but in a way it’s good we didn’t have more because it’s harder to stay awake when you have nothing to do.” (The mission included a sleep reduction study, which meant the crew only got five hours of sleep a night five days a week.) “With the time I did have, I read a lot,” he said. He also drew, kept a journal, and “wrote bad haikus.” Because of the sleep study, Ellie didn’t read as much. “For me, had I tried to read or sit and do anything not interactive, I would have fallen asleep,” she said.

The crew’s art gallery, where they hung drawing and haikus they wrote.

Journaling and drawing were popular ways to pass the time. “We developed a crew art gallery on one of the walls,” Will said. They also played board games—in particular a game where you score points by making words with lettered tiles on a 15×15 grid. (Yes that one!) “Playing [that game] with two scientists wasn’t always fun though,” Ellie joked, referencing some of the more obscure vocabulary words Will and Michael had at the ready. “I was like, ‘What does that word mean?’ ‘Well that word means lava flow,” she said laughing. (The rest of the crew assured us she fared just fine.)

Chi tried reading, but found it difficult due to the dimmed lights that were part of an onboard light study. She took on a side project instead: 1000 paper cranes. “There is a story in Japan—I’m half Japanese—that if you make a 1000 cranes, it’s supposed to grant you a wish,” she said. She gave hers to her grandmother.

On weekends, the crew got eight hours of sleep, which they celebrated with “Sophisticated Saturdays!” “Coming in, we all brought an outfit that was a little fancy,” Ellie said. (Like a tie, a vest, an athletic dress—that kind of thing.) “We would only put it on Saturday evenings, and we’d have dinner on the first level at the one and only table we could all sit at and face each other,” she said. “We would pretend it was a different fancy restaurant every week.”

The table set for a “civilized” Saturday dinner. Once the crew’s hydroponics grew, they were able to add some greenery to the table.

“It was a way to feel more civilized,” Will said, who then offered another great use of their free time: establishing good habits. “I would use the free time to journal, for example. I’d just keep it up every day. That and stretching. Hydrating. Flossing.”

Like real astronauts, you were in contact with Mission Control and further monitored by HERA personnel. Was it weird being on camera all the time?

HERA personnel and the monitors they use for a typical HERA mission.

“I was always aware of it,” Michael said, “but I don’t think it changed my behavior. It’s not like I forgot about it. It was always there. I just wasn’t willing to live paranoid for 45 days.” Ellie agreed. “It was always in the back of my mind,” she said, further adding that they wore microphones and various other sensors. “We were wired all the time,” she said.

After the study, the crew met up with the people facilitating the experiments, sometimes for the first time. “It was really fun to meet Mission Control afterwards,” Will said. “They had just been this voice coming from the little boxes. It was great getting to meet them and put faces to the voices,” he said. “Of course, they knew us well. Very well.”

Exploring an Asteroid Without Leaving Earth

This 45 day mission – which began May 5, 2018 and ends today, June 18 – will help our researchers learn how isolation and close quarters affect individual and group behavior. This study at our Johnson Space Center prepares us for long duration space missions, like a trip to an asteroid or even to Mars.

The Human Research Exploration Analog (HERA) that the crew members will be living in is one compact, science-making house. But unlike in a normal house, these inhabitants won’t go outside for 45 days. Their communication with the rest of planet Earth will also be very limited, and they won’t have any access to internet. So no checking social media, kids!

The only people they will talk with regularly are mission control and each other.

The HERA XVII crew is made up of 2 men and 2 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 would-be astronauts are:

William Daniels

Chiemi Heil

Eleanor Morgan

Michael Pecaut

What will they be doing?

The crew are going on a simulated journey to an asteroid, a 715-day journey that we compress into 45 days. They will fly their simulated exploration vehicle around the asteroid once they arrive, conducting several site surveys before 2 of the crew members will participate in a series of virtual reality spacewalks.

They will also be participating in a suite of research investigations and will also engage in a wide range of operational and science activities, such as growing and analyzing plants and brine shrimp, maintaining and “operating” an important life support system, exercising on a stationary bicycle or using free weights, and sharpening their skills with a robotic arm simulation.

During the whole mission, they will consume food produced by the Johnson Space Center Food Lab – the same food that the astronauts enjoy on the International Space Station – which means that it needs to be rehydrated or warmed in a warming oven.

This simulation means that even when communicating with mission control, there will be a delay on all communications ranging from 1 to 5 minutes each way.

A few other details:

The crew follows a timeline that is similar to one used for the space station crew.

They work 16 hours a day, Monday through Friday. This includes time for daily planning, conferences, meals and exercise.

Mission: May 5 - June 18, 2018

But beware! While we do all we can to avoid crises during missions, crews need to be able to respond in the event of an emergency. The HERA crew will conduct a couple of emergency scenario simulations, including one that will require them to respond to a decrease in cabin pressure, potentially finding and repairing a leak in their spacecraft.

Throughout the mission, researchers will gather information about living in confinement, teamwork, team cohesion, mood, performance and overall well-being. The crew members will be tracked by numerous devices that each capture different types of data.

More Space...in Space

How do you create more space…in space? The Bigelow Expandable Activity Module (BEAM) is one solution to creating additional working space on the International Space Station.

BEAM will be deployed to its full size this Thursday, May 26, and begin its two-year technology demonstration attached to the space station. The astronauts aboard will first enter the habitat on June 2, and re-enter the module several times a year throughout the test period. While inside, they will retrieve sensor data and assess conditions inside the module.

Why Use an Expandable Habitat?

Expandable habitats are designed to take up less room on a spacecraft, but provide greater volume for living and working in space once expanded. This first test of an expandable module will allow investigators to gauge how well it performs and specifically, how well it protects against solar radiation, space debris and the temperature extremes of space.

BEAM launched April 8 aboard a SpaceX Dragon cargo spacecraft, and is an example of our increased commitment to partnering with industry to enable the growth of commercial use of space.

Get Involved!

During expansion, we will provide live Mission Control updates on NASA Television starting at 5:30 a.m. EDT on Thursday, May 26.

Make your own origaBEAMi!

To coincide with the expansion, here is a simple and fun activity called “origaBEAMi” that lets you build your own miniature inflatable BEAM module. Download the “crew procedures” HERE that contain step-by-step instructions on how to print and fold your BEAM module. You can also view a “how to” video HERE.

Top 10 Ways the Space Station is Helping Get Us to Mars

Believe it or not, the International Space Station is paving our way to Mars. Being the only microgravity laboratory in which long-duration investigations can take place, it provides deeper understanding of how the human body reacts to long-term spaceflight. Here are the top 10 ways the space station is helping us on our journey to the Red Planet:

10: Communication Delays

Have you ever sent a text and got frustrated when it took longer than 3 seconds to send? Imaging communicating from Mars where round-trip delays could take up to 31 minutes! Our Comm Delay Assessment studies the effects of delayed communications for interplanetary crews that have to handle medical and other emergencies in deep space.

9. Astronaut Functional Performance

After a long nights sleep, do you ever feel a bit clumsy when you first get out of bed? Imagine how crew members might feel after spending six months to a year in microgravity! Our Field Test investigation is working to understand the extend of physical changes in astronauts who live in space for long periods of time, with an aim toward improving recovery time and developing injury prevention methods for future missions.

8. Psychological Impacts of Isolation and Confinement

In order to study the behavioral issues associated with isolation and confinement, researchers evaluate the personal journals of space station crew members. These study results provide information to help prepare us for longer duration spaceflight.

7. Impacts on Vision

Did you know that long duration spaceflight can often cause changes to crew members’ vision? It can, and our Ocular Health study monitors microgravity-induced visual impairment, as well as changes believed to arise from elevated intracranial pressure. All of this work hopes to characterize how living in microgravity can affect the visual, vascular and central nervous systems.

6. Immune Responses

An important aspect of our journey to Mars is the need to understand how long-duration spaceflight affects they way crew members’ bodies defend agains pathogens. Our Integrated Immune investigation collects and analyzes blood, urine and saliva samples from crew members before, during and after spaceflight to monitor changes in the immune system.

5. Food for Long-Duration Crews

Just like a hiker preparing for a long trek, packing the foods that will give you the most energy for the longest amount of time is key to your success. This is also true for astronauts on long-duration missions. Our Energy investigation measures a crew members’ energy requirements, which is a crucial factor needed for sending the correct amount of the right types of food to space.

4. Exercise for Long-Term Missions

Rigorous exercise is already a regular part of astronauts’ routines, and continuing that focus will be critical to keeping crew members’ bodies strong and ready for a mission to Mars and a healthy return to Earth. Our Sprint investigation is studying the best combination of intensity and duration for exercise in space.

3. Determine Best Habitat/Environment for Crews

Have you ever complained about your room being too small? Imagine living in cramped quarters with an entire crew for months on a Mars mission! Our Habitability investigation collects observations that will help spacecraft designers understand how much habitable volume is required, and whether a mission’s duration impacts how much space crew members need.

2. Growing Food in Space

There’s nothing like fresh food. Not only does it provide valuable nutrition for astronauts, but can also offer psychological benefits from tending and harvesting the crops. Our Veggie investigation studies how to best utilize a facility aboard the space station for growing fresh produce in microgravity.

1. Manufacturing Items in Space

When crews head to Mars, there may be items that are unanticipated or that break during the mission. Our 3-D Printing in Zero-G Technology Demonstration would give crews the ability to manufacture new objects on demand while in space.

“Nos Interstícios do Pertencer: Entre a Busca e o Florescer”

Assim como os seres vivos dependem de um ambiente adequado para seu desenvolvimento e sobrevivência, nós também, em nossa jornada, buscamos, a cada etapa, encontrar nosso habitat ideal. Um espaço que nos abrace, nos permita crescer, evoluir, conectar. Mas, e quando esse espaço parece distante? Quando nos sentimos perdidos, deslocados, como se a nossa essência não coubesse onde estamos? Não é a dor do não pertencimento uma sombra silenciosa que nos persegue, que nos faz questionar: “Onde é o meu lugar? Por que não consigo encontrar o meu?”.

Essa frustração, muitas vezes profunda e esmagadora, nos leva a uma encruzilhada: insistimos em permanecer onde não somos vistos, onde a respiração parece faltar, onde a luz se esconde? Ou, finalmente, nos permitimos a busca pelo nosso verdadeiro espaço, aquele onde o ar é mais leve e o ser se expande?

O emocional, por vezes, nos mantém aprisionados a ambientes que não nos cabem, a lugares apertados, dolorosos, onde não somos nutridos. Mesmo sabendo, no fundo, que esses lugares não são nossos, insistimos. Buscamos a aceitação que nos parece escapar, como um vento fugaz. Mas será que, ao insistir, não estamos, na verdade, nos afastando de nossa própria evolução? Será que o pertencimento que tanto almejamos não está, de fato, em aprender a nos encontrar, antes de buscar um lugar que nos abrace?

Talvez, a dor do não pertencimento seja, na realidade, uma oportunidade disfarçada. Uma chance de refletir sobre o que realmente precisamos para crescer, para florescer. Não seria, então, o desconforto uma porta que se abre para a liberdade de ser quem somos? O crescimento começa muitas vezes quando nos vemos desafiados a sair dos espaços apertados, a questionar o que nos mantém estagnados.

O verdadeiro pertencimento não se encontra onde há sufocamento, mas onde há liberdade para ser. Talvez o maior desafio seja olhar para dentro e perguntar: “Onde estou me perdendo em busca do que já me pertence?” O lugar onde somos capazes de crescer não é o que outros definem, mas aquele que nós, com coragem, escolhemos abraçar.

E se o verdadeiro pertencimento não fosse uma busca fora de nós, mas uma construção interna, algo que se desvela à medida que nos permitimos florescer no espaço que é nosso por direito? Talvez, no fim das contas, o maior pertencimento seja o que encontramos quando nos libertamos das amarras que nos prendem ao que não nos cabe. É, talvez, no espaço vazio do desapego, que podemos finalmente ser, e sentir, que pertencemos.

Kindergarten Habitats & High School Design

Along with returning to my studies I have been visiting classes to talk programming, space and backwards design.

Kindergarteners love hands on work and it's one of the best ways to teach a new concept. During "L" week I challenged students to design a Lunar Habitat. This is apparently really hard to describe to a Kindergartener. After showing pictures of a habitat and making ones out of construction paper the idea clicked after building habitats out of Legos, Bristle Blocks, Tinker Toys and Mega Blocks. The definition best used to describe the Lunar Habitat to Kindergarteners is- "A place where astronauts can live on the Moon without a spacesuit on. It provides resources (like water, air and power) that the moon doesn't have." We also made a Yeti dance on Google's Made With Code website, drew astronaut's EVA suits and ate astronaut ice cream.

Once again high schoolers have been assigned the dreaded toothpick bridge project. I have friends who are therapists and they say this project is a family buster. I visited freshman science classes from my old high schooler to talk about backwards design. I shared how backwards design can help them in their bridge project, real life applications of backwards design while chatting about my NASA projects and admitted what I wish I knew as a freshman. When talking about backwards design I described that the design stage of a project should take the most brain power and more time then expected. Once a design is made you need to think about how much time each stage of production will take, what materials you need and if you learned as much as you can about the project so unknowns are resolved.

Tips for high school freshman I have are...

1) Keep alternate forms of postsecondary education and options in mind like Community College, ROTC (Reserve Officers' Training Corps), Technical Colleges, Study Abroad, Americorps and even taking a year off between high school and college.

2) Take honors classes only if the topic interests you.

3) Find a paid internship to replace you generic summer job (even as a freshman). This way you will be paid to do something meaningful that you are interested in.

4) Network with folks in your community that have your dream job. Ask CEOs, managers and other company leaders if you can shadow them. Ask for a tour of a business that you are interested in.

Although I use lesson plans I write about in previous posts some of the best lessons come from getting off topic. Building the habitats out of materials and talking about freshman advice was totally unplanned but still valuable.
