The Exploration Behind the Inspiration at NASA

Are we alone? How did we get here? Where are we headed?

At NASA, our mission is to explore. We visit destinations in our solar system and study worlds beyond to better understand these big questions.

We also dream. We dream of traveling to distant worlds, and what that might be like. In the video above you can see fanciful, imagined adventures to real places we’ve studied at NASA.

How We Did It

Check out how we created these otherworldly scenes in the video below. A NASA videographer used green screens to add motion and real people to bring life to our series of solar system and exoplanet travel posters.

Let’s dive into one example from the video. The shot of kayaking on Titan showcases the real rivers and lakes of liquid methane and ethane that slosh and flow on Saturn's largest moon. Titan's mysterious surface was revealed by our Cassini spacecraft, which also deployed the European Space Agency’s Huygens probe to the surface. The atmosphere on Titan is so thick, and the gravity so light, that with each strike of a paddle, you might be lofted above the swift current as you ride the tides through a narrow strait called the Throat of Kraken. NASA scientist Mike Malaska studies Titan and collaborated on the poster featured in the video. His research informed the artwork, and so did a hobby: kayaking. Those ultra-cold chemical seas might be even more of a challenge than shown here. Your boat might crack, or even dissolve, Malaska said.

We’ll learn more about Titan when our Dragonfly mission of dual quadcoptors — rotorcraft with eight blades each — visits the icy moon in 2034.

Science Never Stops

Our understanding of other worlds is always evolving, and sometimes we learn new details after we illustrate our science. In one of our travel posters, we show a traveler standing on the surface of exoplanet Kepler-16b with two shadows formed by the planet’s two suns. The planet does indeed orbit two stars, but with later size and mass refinements, we now think it would be hard to stand there and enjoy a binary sunset. There isn't a solid surface to stand on a gas planet, and that's what Kepler-16b now appears to be!

In addition to sharing how sublime science can be, these scenes are a reminder that there are lots of careers in the space program, not just scientist, engineer, or astronaut. A creative team at NASA’s Jet Propulsion Laboratory in Southern California produced the travel posters, originally to help share the work of NASA's Exoplanet Exploration Program. They are the result of lots of brainstorming and discussion with real NASA scientists, engineers, and expert communicators. The video versions of these spacey travel scenes were produced by visualization experts at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

All of this work is meant to inspire, and to explore the edge of possibility. It’s also an invitation. With science, we’re stepping into the future. Join us?

Earth Day at Home with NASA

NASA Spotlight: Astronaut Jonny Kim

Dr. Jonny Kim was selected by NASA to join the 2017 Astronaut Candidate Class. He reported for duty in August 2017 and having completed the initial astronaut candidate training is now eligible for mission assignments to the International Space Station, the Moon and eventually Mars. A U.S. Navy SEAL, Kim completed more than 100 combat operations. Kim was commissioned as a naval officer through an enlisted-to-officer program and earned his degree in mathematics at the University of San Diego and a doctorate of medicine at Harvard Medical School. Born and raised in Los Angeles, California to Korean-American immigrants, he enjoys spending time with his family, outdoor activities, academic and professional mentoring, strength training and lifelong learning. 

Dr. Kim took some time from his job as a NASA astronaut to answer questions about his life and career! Enjoy: 

Why did you apply to be an astronaut?

For many reasons. I think that humans are natural explorers. There is a calling in all of us to explore the unknown, push the boundaries and redefine what is possible. I’m drawn to the physical and mental challenges of space exploration and the teamwork required to complete such an objective. And finally, the opportunity to do something good for our country, for humanity, and to inspire the next generation of thinkers, leaders, explorers and scientists.

What was your favorite memory from astronaut training?

I’m a big believer that people can grow stronger bonds with each other when they succeed through shared hardship. And I think that developing relationships with one another is one of the best ways to forge successful team skills to be successful in any endeavor. With that context, I can tell you that my favorite memory from astronaut training was traversing the deep canyon slots of the Utah Canyon Lands for almost 2 weeks with my classmates. We hiked trails, climbed canyons, swam through deep, dark, cold and murky waters and forged through uncertainty, all while being together. This shared hardship was not only fun, but it helped us grow closer to one another. It’s one of the fondest memories I have when I think about my amazing classmates, and through that shared hardship, I know I can count on any one of my fellow astronauts when the going gets tough.

If you could play any song during launch, what would it be?

Don’t Stop Believin’ by Journey.

What advice would you give to your younger self?

I would tell myself to always follow your passion, never stature or money, because following a life of passion is long-term, sustainable and usually helps others. Be accountable for your mistakes and failures, and maintain the humility to learn from those mistakes and failures. And finally, I would caution myself that all worthwhile goals are difficult to obtain, but with the right attitude and hard work, you can accomplish anything.

How did your time as a Navy Seal impact your astronaut training?

Being a Naval Special Warfare Operator taught me that humans are capable of accomplishing ten times what their bodies and mind tell them. I learned there are no limits in life, and the biggest setback one can have is a poor attitude. I learned the value of strong leadership and accountability. I also learned the meaning of sacrifice, hardship, teamwork, love and compassion. All these traits helped me to develop the hard and soft skills required to be an astronaut.

How do we prepare medically for long duration missions? What tools, resources, medications do we anticipate needing, and how do we figure that out?

This is a great question and the answer is evolving. The way we answer this question is by being thoughtful and consulting the medical communities to weigh the pros and cons of every single decision we make regarding this. Mass plays an important factor, so we have to be mindful of everything we bring and how we train for it.

Who was the first person you called after being selected to be an astronaut?

It would have been my wife but she was with me when I heard the news. The first person I called was my mom.

What is one item from home that you would bring to space?

A picture of my wife and kids.

What does it mean to you to be part of the Artemis generation of astronauts?

It means that I have a duty and obligation to serve humanity’s best interests. To explore the unknown, push boundaries and redefine what’s possible. It means I have an immense opportunity to serve as an example and inspiration to our next generation of leaders and explorers. It also means there is a hard road ahead, and when the mission calls for us, we will be ready.

What are three personal items, besides photos of family and friends, that you would bring with you on your first spaceflight?

An automatic watch, because the engineering behind a timepiece is a beautiful thing. An American flag, because I proudly believe and uphold the principles and ideals our country stands for. And finally, a nice journal that I can put handwritten thoughts on.

Thank you for your time, and good luck on your first spaceflight assignment!

NASA Spotlight: Astronaut Kjell Lindgren 

Kjell N. Lindgren was selected by NASA in 2009. Born in Taiwan while his family was stationed overseas, he spent most of his childhood abroad and returned to the U.S. to complete his education and earn a Doctorate of Medicine from the University of Colorado. He is board certified in emergency and aerospace medicine. After serving as the Deputy Crew Surgeon for Space Shuttle mission STS‐130 and Expedition 24, he was selected to join our astronaut corps. Dr. Lindgren flew on the International Space Station from July 2015 to December 2015 and logged 141 days in space. He participated in two spacewalks and in more than a hundred different scientific experiments. In his free time, Dr. Lindgren enjoys spending time with his family, running, reading, movies, photography and amateur astronomy.

He took some time from being a NASA astronaut to answer questions about his life and career! Enjoy: 

What is one thing you would take to space that would make life easier?

A real R2 unit, of course! Just kidding, but in the future…  Honestly though, life is pretty good on the International Space Station. While it is still a lot like camping (sleeping bags, no running water, rehydrated food) the space station team has really equipped us for success. As you all prepare for YOUR future spaceflight, I would say that the two most useful items I had with me on a daily basis were a pair of scissors and a spoon. The scissors were super useful for cutting plastic wrappers, tape, etc., and opening food packages (much more useful than a knife). And the spoon is the only utensil you need for eating – at least with the food system that we have right now.

Who helped get you to where you are?

Getting this opportunity, becoming an astronaut – that was a team effort for sure. I had so many people walking alongside me on this journey, helping me along the way. My parents set the bit early on – telling me that I could become whatever I wanted through hard work. They really gave me permission to dream big. Teachers and coaches, mentors, co-workers and friends all played a huge part in reaching this goal. Most of all, though, my wife, Kristi and my three kids have been an integral part of this adventure. I would not have this job, and I wouldn’t be successful in it without their love and daily support.

You and your crew mates were the first astronauts to harvest lettuce grown on orbit. How did it taste?

The lettuce tasted like…lettuce, which was a good thing, because if it hadn’t, then it meant we had made a huge mistake. It was so much fun to be a part of that experiment. The payoff, getting to eat fresh grown food on orbit was of course, a lot of fun. But just getting to take care of the lettuce plant, watch it grow in the sterile looking environment of the space station, getting to take care of this living thing on a daily basis, it was good for the soul.

How do you prepare for someone getting hurt or sick in space? 

We train at least two crew members on every expedition to be Crew Medical Officers, or CMOs. They spend about 40 – 50 hours learning how to use the medical equipment and procedures on the space station, so that they can essentially serve as an extension of the flight surgeon in mission control. We have equipment and medication to deal with most minor illnesses and injuries. But because we are in low earth orbit, we can evacuate an ill crew member back to Earth in the event of a severe medical issue. This option won’t be available as we push out further from Earth, so we’ll need more rigorous training and a more comprehensive medical system.

How many times did you apply to be an astronaut?

I was very fortunate and got selected on my first try. I have several friends in the office though, who applied 4 or 5 times before being selected. It is amazing to go through the selection process and to meet others who share your dream. Enjoy the experience and keep applying – it is worth it!

How can I improve my chances of being selected to become an astronaut?

I recommend continuing to do things that you enjoy, continue to build experience at work and maybe look for new opportunities in your job that will grow you in your career and grow you as a leader. But choose opportunities because YOU want to do them, not based on what you think NASA is looking for. There is no one path or experience that leads to becoming an astronaut. We have an amazing diversity of experience and background in the astronaut office.

What advice do you have for the newest astronauts?

Enjoy the journey! Spaceflight is amazing, but even as astronauts, most of us spend 95% of our career on the ground. Enjoy every part of the job, supporting missions as a Spacecraft Communicator (CapCom), verifying procedures for a repair or training for a spacewalk. It is amazing to be a part of the team that launches and supports humans living and working in space. It is an amazing thing.

Which is more exciting: spacewalking or skydiving?

Skydiving was pretty amazing. I got to do quite a bit of it as a member of the Air Force Academy parachute team. But there is nothing quite like doing a spacewalk. It is an indescribable experience, putting hundreds of hours of training to work, the physical and mental challenge of operating in that harsh environment. But the view outside the space station, of the Earth, the stars, the structure of the space station – it was a highlight of my time in space and something I will never forget.

What's the most interesting part about training with the Dragon capsule?

It has been awesome working with the NASA and SpaceX teams as we are preparing to launch in the Crew Dragon capsule. My favorite part of the experience has always been and continues to be the people. Safely sending humans to space and back is one of the most difficult things humanity has ever done. That challenge attracts the best and brightest people from across our country. Getting to work with those folks at NASA and at SpaceX, to experience their enthusiasm, dedication and ingenuity on a daily basis is a gift. It has also been a lot of fun seeing a different approach to human spaceflight. I’m very familiar with how NASA and the Russian Space Agency Roscosmos operate. It has been fun seeing a different perspective and approach.

Can you share your favorite photo or video that you took in space?

Yes! This is my favorite photo of the Milky Way, with a lightning strike illuminating a solar array.

Thanks Dr. Lindgren, and good luck on your next spaceflight!

NASA Spotlight: Astronaut Andrew Feustel

Andrew J. Feustel was selected by NASA in 2000. The Lake Orion, Michigan native has a Ph.D. in the Geological Sciences, specializing in Seismology, and is a veteran of three spaceflights. In 2009, Dr. Feustel served on space shuttle mission STS-125. That mission was the fifth and final mission to service the Hubble Space Telescope that improved the observatory’s capabilities through 2014! Feustel most recently served as Commander on the International Space Station from March 21 through October 4, 2018. In his free time, Dr. Feustel enjoys auto restoration, guitar, water and snow skiing and is a fan of automotive and motorcycle racing.  

He took some time from his job as a NASA astronaut to answer a few questions about his life and career! Enjoy:

While attending Oakland Community College, you worked as an auto mechanic. How does that job and the skills you learned relate to your job now as an astronaut?

I’ve often told people that I believe having this skillset is almost as important as my training in college and university. I relied on those skills almost every day in space and even on the ground while preparing for missions. That skillset has been really helpful in understanding how to maintain and repair equipment for spaceflight. In general, having those general skills of knowing how things fit together, what the structure is, and how things work, even without knowing anything about the particular item, is very helpful in life.

Has there ever been a time as a NASA Astronaut where you had to overcome self-doubt and if so, how did you?

Yes, probably the most impactful time I had to overcome self-doubt was on my very first mission as a rookie doing a spacewalk for the first time and having to make a repair on the Hubble Space Telescope. Since it was my first spacewalk, I didn’t know if I could do it and didn’t know how I would do. However, I had trained for that mission for three years and the training took over when I started the spacewalk. At that point, I didn’t focus on my self-doubt, I focused on my training and was able to carry out the tasks.

What are you most excited about for the upcoming Artemis Moon missions?

I am most excited about the possibility of humans establishing the ability to live off of our planet. To have the capability to exist on another surface. That, to me, is a start. Humans need that capability for us to live on the Moon then to go to Mars.

What did living in space teach you about community and teamwork?

Not just living in space, but working at NASA and training for space missions taught me a lot about community and teamwork. Living in space allows you to use the skills you learn about teamwork while training. While living in space you must rely on each other for everything. It’s important to recognize the value of working as a team. All of the astronauts have a very different mix of skills and that’s a great thing about the astronaut corps. Being successful and staying alive in space relies on community and teamwork.

What kind of impact did living and working in space have on how you view the Earth?

I am more aware of the fragility of our planet and species which is why humans should extend past the Earth. We are fragile as a planet and the Earth is vulnerable to the impacts of us living here. We cannot have zero impact on the planet, we will always have some impact, but the goal is to lessen the damage that we do to Earth to allow us to live here indefinitely if possible.

What or who inspired you to apply to be an astronaut?

I was inspired by reading the obituary of my great-great uncle. He was very successful in the utilities and railroad industry in the Midwest. Reading about his successes made me believe that I could do anything. I was also interested in space travel from a young age. I believed that I would be involved in the space industry. The motivation of understanding what family members had done before me really encouraged me to reach for my dreams and apply.

What book, movie, or show about space and/or astronauts is the most accurate? The least accurate? You wish was accurate?

I’m less concerned about the accuracy of space and space exploration portrayed in movies, but more interested with the creative thought behind them and I am fascinated with ideas and imagination of the people making these movies. Things portrayed as science fiction in the past become science fact in the future.

What's the most common misconception about astronauts / working at NASA?

The most common misconception about astronauts is that we go on spaceflights often. Over 95% of our job is spent working on the ground. People should come to this job because it’s important to space and space exploration. The job entails so much more than going into space yourself, but the good news is it’s all awesome. I have never been bored at my job. There are so many exciting parts of this work that contribute to NASA missions even if it doesn’t always mean being in space.

Can you share your favorite photo or video that you took in space?

My favorite photo is this one of Michigan and Canada. It captures my life – where I lived and everyone that I know and my family and friends – that’s where I consider home. It’s such a beautiful image.

That’s a wrap! Thank you Dr. Feustel for your time!

Becoming a Space Scientist

Astronauts train all over the world, including at Johnson Space Center. Here, they learn not just how to live aboard the International Space Station, but also how to conduct science in microgravity.

Astronauts serve as the eyes and hands of researchers while their experiments are in space, so they must be trained in everything from using a microscope, to maintaining the equipment for combustion experiments.

Check out this week’s episode of NASA Explorers as we go to class with an astronaut.

It’s a Bird! It’s a Plane! It’s NASA’s Five Newest Airborne Campaigns!

We’re not just doing research in space! From the land, the sea and the sky, we study our planet up close. Right now, we’re gearing up for our newest round of Earth Expeditions, using planes, boats and instruments on the ground to study Earth and how it’s changing.

The newest round of campaigns takes place all across the United States – from Virginia to Louisiana to Kansas to California.

The five newest missions will combine measurements from the ground, the sea, air and space to investigate storms, sea level rise and processes in the atmosphere and ocean.

Let’s meet the newest Earth science missions:

1. IMPACTS

The Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms will start from Wallops Flight Facility in Virginia to understand how bands of snow form during winter storms in the East Coast. This research will help us better forecast intense snowfall during extreme winter weather.

2. ACTIVATE

Flying out of Langley Research Center, the Aerosol Cloud Meteorology Interactions over the Western Atlantic Experiment is studying how specific types of clouds over oceans affect Earth’s energy balance and water cycle. The energy balance is the exchange of heat and light from the Sun entering Earth’s atmosphere vs. what escapes back into space.

3. Delta-X

Farther south, Delta-X is flying three planes around the Mississippi River Delta to study how land is deposited and maintained by natural processes. Studying these processes can help us understand what will happen as sea levels continue to rise.

4. DCOTSS

Heading out to the Midwest this summer, the Dynamics and Chemistry of the Summer Stratosphere mission will study how thunderstorms can carry pollutants from high in the atmosphere deep into the lower stratosphere, where they can affect ozone levels.

5. S-MODE

About 200 miles off the coast of San Francisco, the Sub-Mesoscale Ocean Dynamics Experiment is using ships, planes and gliders to study the impact that ocean eddies have on how heat moves between the ocean and the atmosphere.

These missions are kicking off in January, so stay tuned for our updates from the field! You can follow along with NASA Expeditions on Twitter and Facebook.
