Science Coming Soon To A Space Station Near You

River Bends Through 1,000-Foot Canyons

An astronaut aboard the International Space Station shot this photograph of the Green River flowing through deep, red rock canyons in eastern Utah. A main tributary of the Colorado River, the Green flows 730 miles (1,175 kilometers) through Wyoming, Colorado and Utah. The portion of the Green River in this image is just north of Canyonlands National Park.

Bowknot Bend was named for the way the river loops back on itself. Located in Labyrinth Canyon about 25 miles west of Moab, Utah, this river bend runs 7.5 miles (12 kilometers) in a circular loop and ends up 1,200 feet (360 meters) from where it first started. When the two sides of the river merge someday, Bowknot Bend will break off from the main channel and form a lake.

Calling Long-Distance: 10 Stellar Moments in 2022 for Space Communications and Navigation

Just like your phone needs Wi-Fi or data services to text or call – NASA spacecraft need communication services.

Giant antennas on Earth and a fleet of satellites in space enable missions to send data and images back to our home planet and keep us in touch with our astronauts in space. Using this data, scientists and engineers can make discoveries about Earth, the solar system, and beyond. The antennas and satellites make up our space communications networks: the Near Space Network and Deep Space Network.

Check out the top ten moments from our space comm community: 

1. Space communication networks helped the Artemis I mission on its historic journey to the Moon. From the launch pad to the Moon and back, the Near Space Network and Deep Space Network worked hand-in-hand to seamlessly support Artemis I. These networks let mission controllers send commands up to the spacecraft and receive important spacecraft health data, as well as incredible images of the Moon and Earth.

2. Spacecraft can range in size – from the size of a bus to the size of a cereal box. In May 2022, we launched a record-breaking communication system the size of a tissue box. TBIRD showcases the benefits of a laser communications system, which uses infrared light waves rather than radio waves to communicate more data at once. Just like we have upgraded from 3G to 4G to 5G on our phones, we are upgrading its space communications capabilities by implementing laser comms!

3. The Deep Space Network added a new 34-meter (111-foot) antenna to continue supporting science and exploration missions investigating our solar system and beyond. Deep Space Station 53 went online in February 2022 at our Madrid Deep Space Communications Complex. It is the fourth of six antennas being added to expand the network’s capacity.

4. You’ve probably seen in the news that there are a lot of companies working on space capabilities. The Near Space Network is embracing the aerospace community’s innovative work and seeking out multiple partnerships. In 2022, we met with over 300 companies in hopes of beginning new collaborative efforts and increasing savings.

5. Similar to TBIRD, we're developing laser comms for the International Space Station. The terminal will show the benefits of laser comms while using a new networking technique called High Delay/Disruption Tolerant Networking that routes data four times faster than current systems. This year, engineers tested and proved the capability in a lab.

6. In 2021, we launched the James Webb Space Telescope, a state-of-the-art observatory to take pictures of our universe. This year, the Deep Space Network received the revolutionary first images of our solar system from Webb. The telescope communicates with the network’s massive antennas at three global complexes in Canberra, Australia; Madrid, Spain; and Goldstone, California.

7. Just like we use data services on our phone to communicate, we'll do the same with future rovers and astronauts exploring the Moon. In 2022, the Lunar LTE Studies project, or LunarLiTES, team conducted two weeks of testing in the harsh depths of the Arizona desert, where groundbreaking 4G LTE communications data was captured in an environment similar to the lunar South Pole. We're using this information to determine the best way to use 4G and 5G networking on the Moon.

8. A new Near Space Network antenna site was unveiled in Matjiesfontein, South Africa. NASA and the South African Space Agency celebrated a ground-breaking at the site of a new comms antenna that will support future Artemis Moon missions. Three ground stations located strategically across the globe will provide direct-to-Earth communication and navigation capabilities for lunar missions.

9. Quantum science aims to better understand the world around us through the study of extremely small particles. April 14, 2022, marked the first official World Quantum Day celebration, and we participated alongside other federal agencies and the National Quantum Coordination Office. From atomic clocks to optimizing laser communications, quantum science promises to greatly improve our advances in science, exploration, and technology.

10. We intentionally crashed a spacecraft into an asteroid to test technology that could one day be used to defend Earth from asteroids. The Double Asteroid Redirection Test, or DART, mission successfully collided with the asteroid Dimorphos at a rate of 4 miles per second (6.1 kilometers per second), with real-time video enabled by the Deep Space Network. Alongside communications and navigation support, the global network also supports planetary defense by tracking near-Earth objects.

We look forward to many more special moments connecting Earth to space in the coming year.

10 Questions for Our New Head of Science

Guess what?! We have a new lead for our science missions, and we’re excited to introduce him to you. Recently, NASA Administrator Charles Bolden has named Thomas Zurbuchen as the new head of our organization for science missions. Let’s get to know him...

Zurbuchen was most recently a professor of space science and aerospace engineering at the University of Michigan in Ann Arbor. He was also the university’s founding director of the Center for Entrepreneurship in the College of Engineering.

Zurbuchen’s experience includes research in solar and heliospheric physics, experimental space research, space systems and innovation and entrepreneurship.

We asked him a few questions to see what he has in store for science at NASA…let’s take a look:

1. What is your vision for science at NASA?

Right now, I am focusing on my team and I am learning how I can help them achieve the goals we have; to design and build the missions we are currently working on. Once the presidential transition is complete, we will engage in strategic activity with that team. It has been my experience that the best ideas always come from great and diverse teams working together. I intend to do that here as well.

2. What solar system destination are you most eager for NASA to explore?

Tough question to answer. Basically, I want to go where there are answers to the most important questions. One question on my mind is the origin of extraterrestrial life. Some parts of the answer to this question can be answered at Mars, some at Europa or other moons in the outer solar system like Enceladus. Other parts of the answer is around other stars, where we have found thousands of planets…some of which are amazingly similar to Earth!

3. With raw images posted to several websites from our missions, what’s one thing you hope members of the public can help NASA do with that powerful data?

I hope that people all over the world play with the data and find new ways to explore. It’s almost like hanging out in the most amazing libraries talking about nature. Many of the books in this library have never been opened and curious minds can find true treasures in there. I know that there are over a billion data-products NASA is making available about the Earth – it’s a treasure chest!

4. In your opinion, what big science breakthrough from the past informs missions of today?

In science, everything we do builds on successes and also failures of the past. Sometimes we forget our failures or near-failures, which tend to teach us a lot about what to do and what not to do. One of my favorite stories is about the Explorer 1 mission: first they observed almost nothing, until they realized that there was so much radiation that the detectors were chocking. The Van Allen Probes is a mission that are conducting the best exploration today of these radiation belts, discovered by Explorer 1. Our exploration history is full of stories like that.

5. Behind every pretty space image is a team of scientists who analyze all the data to make the discovery happen. What do you wish the public knew about the people and work that goes into each of those pretty pictures?

I wish people knew that every picture they see, every data-set they use, is a product of a team. One of the most exhilarating facts of working in space is to be able to work in teams composed of some of the nicest and most interesting people I have ever met. There are some super-famous people I run with every time we are in the same town, others who like to play music and listen to it, and some who have been in space or climbed mountains.

6. If you were a member of the public, what mission events in the next year would you be most excited about?

The public’s lives will be directly affected by our missions in our Earth Science portfolio. Some of them are done together with NOAA, our sister agency responsible for forecasts. For example, GOES will feature a lightning detector that will enable better predictions of storms. We are also launching CYGNSS in December. This NASA mission, composed of 8 spacecraft will provide unique and high-resolution data designed to provide a deeper understanding and better prediction for hurricanes globally.

7. NASA science rewrites textbooks all the time. What do you hope the kids of tomorrow will know as facts that are merely hypothesis today?

I hope they will know about life elsewhere. They will learn how life evolves, and where there is life today.

8. NASA has explored planets within our solar system. With the launch of the James Webb Space Telescope in 2020, what do you hope we learn about distant worlds?

James Webb is going to allow us to go back in time and look at the first stars and first galaxies. This is something we have never seen – we can only guess what will happen. James Webb is going to allow us to look at many, many more planets around other stars and will allow us to start doing the kind of research that links to the question about how habitable life is there.

9. What sort of elements make for an exciting new science discovery? What do you hope is the next big discovery?

Almost always, an exciting discovery is a surprise. Sometimes, discoveries happen because we are looking for something totally different. The biggest discoveries are the ones that change everything we thought before. All of a sudden, nature wags the finger at us and says “you are wrong!” That is how you know you are up to something new.

I hope the next big discovery tells us about the origin of the 95% of the universe we don’t know enough about. We call these 95% “Dark Energy” and “Dark Matter”, but – to be honest – we really don’t know. So, we are today living in a time where we know with 100% certainty that we don’t know what makes up 95% of our universe.

10. In your opinion, why should people care about the science at NASA?

They should care because we improve and protect lives on Earth. They should also care because we make the world we live in bigger. This is because we find things out we never knew, which creates new opportunities for humankind. Some of these opportunities are near-term – they are patents, innovations, companies or great educations. But, some of them are long-term – they change how we think about life itself.

What would you say to a person who has few opportunities to excel due to social determinants that he cannot control (nationality, money, family, education)?

Caution: Universe Work Ahead 🚧

We only have one universe. That’s usually plenty – it’s pretty big after all! But there are some things scientists can’t do with our real universe that they can do if they build new ones using computers.

The universes they create aren’t real, but they’re important tools to help us understand the cosmos. Two teams of scientists recently created a couple of these simulations to help us learn how our Nancy Grace Roman Space Telescope sets out to unveil the universe’s distant past and give us a glimpse of possible futures.

Caution: you are now entering a cosmic construction zone (no hard hat required)!

This simulated Roman deep field image, containing hundreds of thousands of galaxies, represents just 1.3 percent of the synthetic survey, which is itself just one percent of Roman's planned survey. The full simulation is available here. The galaxies are color coded – redder ones are farther away, and whiter ones are nearer. The simulation showcases Roman’s power to conduct large, deep surveys and study the universe statistically in ways that aren’t possible with current telescopes.

One Roman simulation is helping scientists plan how to study cosmic evolution by teaming up with other telescopes, like the Vera C. Rubin Observatory. It’s based on galaxy and dark matter models combined with real data from other telescopes. It envisions a big patch of the sky Roman will survey when it launches by 2027. Scientists are exploring the simulation to make observation plans so Roman will help us learn as much as possible. It’s a sneak peek at what we could figure out about how and why our universe has changed dramatically across cosmic epochs.

This video begins by showing the most distant galaxies in the simulated deep field image in red. As it zooms out, layers of nearer (yellow and white) galaxies are added to the frame. By studying different cosmic epochs, Roman will be able to trace the universe's expansion history, study how galaxies developed over time, and much more.

As part of the real future survey, Roman will study the structure and evolution of the universe, map dark matter – an invisible substance detectable only by seeing its gravitational effects on visible matter – and discern between the leading theories that attempt to explain why the expansion of the universe is speeding up. It will do it by traveling back in time…well, sort of.

Seeing into the past

Looking way out into space is kind of like using a time machine. That’s because the light emitted by distant galaxies takes longer to reach us than light from ones that are nearby. When we look at farther galaxies, we see the universe as it was when their light was emitted. That can help us see billions of years into the past. Comparing what the universe was like at different ages will help astronomers piece together the way it has transformed over time.

This animation shows the type of science that astronomers will be able to do with future Roman deep field observations. The gravity of intervening galaxy clusters and dark matter can lens the light from farther objects, warping their appearance as shown in the animation. By studying the distorted light, astronomers can study elusive dark matter, which can only be measured indirectly through its gravitational effects on visible matter. As a bonus, this lensing also makes it easier to see the most distant galaxies whose light they magnify.

The simulation demonstrates how Roman will see even farther back in time thanks to natural magnifying glasses in space. Huge clusters of galaxies are so massive that they warp the fabric of space-time, kind of like how a bowling ball creates a well when placed on a trampoline. When light from more distant galaxies passes close to a galaxy cluster, it follows the curved space-time and bends around the cluster. That lenses the light, producing brighter, distorted images of the farther galaxies.

Roman will be sensitive enough to use this phenomenon to see how even small masses, like clumps of dark matter, warp the appearance of distant galaxies. That will help narrow down the candidates for what dark matter could be made of.

In this simulated view of the deep cosmos, each dot represents a galaxy. The three small squares show Hubble's field of view, and each reveals a different region of the synthetic universe. Roman will be able to quickly survey an area as large as the whole zoomed-out image, which will give us a glimpse of the universe’s largest structures.

Constructing the cosmos over billions of years

A separate simulation shows what Roman might expect to see across more than 10 billion years of cosmic history. It’s based on a galaxy formation model that represents our current understanding of how the universe works. That means that Roman can put that model to the test when it delivers real observations, since astronomers can compare what they expected to see with what’s really out there.

In this side view of the simulated universe, each dot represents a galaxy whose size and brightness corresponds to its mass. Slices from different epochs illustrate how Roman will be able to view the universe across cosmic history. Astronomers will use such observations to piece together how cosmic evolution led to the web-like structure we see today.

This simulation also shows how Roman will help us learn how extremely large structures in the cosmos were constructed over time. For hundreds of millions of years after the universe was born, it was filled with a sea of charged particles that was almost completely uniform. Today, billions of years later, there are galaxies and galaxy clusters glowing in clumps along invisible threads of dark matter that extend hundreds of millions of light-years. Vast “cosmic voids” are found in between all the shining strands.

Astronomers have connected some of the dots between the universe’s early days and today, but it’s been difficult to see the big picture. Roman’s broad view of space will help us quickly see the universe’s web-like structure for the first time. That’s something that would take Hubble or Webb decades to do! Scientists will also use Roman to view different slices of the universe and piece together all the snapshots in time. We’re looking forward to learning how the cosmos grew and developed to its present state and finding clues about its ultimate fate.

This image, containing millions of simulated galaxies strewn across space and time, shows the areas Hubble (white) and Roman (yellow) can capture in a single snapshot. It would take Hubble about 85 years to map the entire region shown in the image at the same depth, but Roman could do it in just 63 days. Roman’s larger view and fast survey speeds will unveil the evolving universe in ways that have never been possible before.

Roman will explore the cosmos as no telescope ever has before, combining a panoramic view of the universe with a vantage point in space. Each picture it sends back will let us see areas that are at least a hundred times larger than our Hubble or James Webb space telescopes can see at one time. Astronomers will study them to learn more about how galaxies were constructed, dark matter, and much more.

The simulations are much more than just pretty pictures – they’re important stepping stones that forecast what we can expect to see with Roman. We’ve never had a view like Roman’s before, so having a preview helps make sure we can make the most of this incredible mission when it launches.

Roman’s Five-Year Forecast: A Downpour of Data!

Our Nancy Grace Roman Space Telescope recently passed a major review of the ground system, which will make data from the spacecraft available to scientists and the public.

Since the telescope has a gigantic field of view, it will be able to send us tons of data really quickly — about 500 times faster than our Hubble Space Telescope! That means Roman will send back a flood of new information about the cosmos.

Let’s put it into perspective — if we printed out all of Roman’s data as text, the paper would have to hurtle out of the printer at 40,000 miles per hour (64,000 kilometers per hour) to keep up! At that rate, the stack of papers would tower 330 miles (530 kilometers) high after a single day. By the end of Roman’s five-year primary mission, the stack would extend even farther than the Moon! With all this data, Roman will bring all kinds of cosmic treasures to light, from dark matter and dark energy to distant planets and more!

Space Missions Come Together in Colorado

Our leadership hit the road to visit our commercial partners Lockheed Martin, Sierra Nevada Corp. and Ball Aerospace in Colorado. They were able to check the status of flight hardware, mission operations and even test virtual reality simulations that help these companies build spacecraft parts.

Let’s take a look at all the cool technology they got to see…

Lockheed Martin

Lockheed Martin is the prime contractor building our Orion crew vehicle, the only spacecraft designed to take humans into deep space farther than they’ve ever gone before.

Acting NASA Deputy Administrator Lesa Roe and Acting NASA Administrator Robert Lightfoot are seen inside the CHIL…the Collaborative Human Immersive Laboratory at Lockheed Martin Space Systems in Littleton, Colo. Lockheed Martin’s CHIL enables collaboration between spacecraft design and manufacturing teams before physically producing hardware.

Cool shades! The ability to visualize engineering designs in virtual reality offers tremendous savings in time and money compared to using physical prototypes. Technicians can practice how to assemble and install components, the shop floor can validate tooling and work platform designs, and engineers can visualize performance characteristics like thermal, stress and aerodynamics, just like they are looking at the real thing.

This heat shield, which was used as a test article for the Mars Curiosity Rover, will now be used as the flight heat shield for the Mars 2020 rover mission.

Fun fact: Lockheed Martin has built every Mars heat shield and aeroshell for us since the Viking missions in 1976.

Here you can see Lockheed Martin’s Mission Support Area. Engineers in this room support six of our robotic planetary spacecraft: Mars Odyssey, Mars Reconnaissance Orbiter, MAVEN, Juno, OSIRIS-REx and Spitzer, which recently revealed the first known system of seven Earth-size planets around a single star, TRAPPIST-1. They work with NASA centers and the mission science teams to develop and send commands and monitor the health of the spacecraft.

See all the pictures from the Lockheed Martin visit HERE. 

Sierra Nevada Corporation

Next, Lightfoot and Roe went to Sierra Nevada Corporation in Louisville, Colo. to get an update about its Dream Chaser vehicle. This spacecraft will take cargo to and from the International Space Station as part of our commercial cargo program.

Here, Sierra Nevada Corporation’s Vice President of Space Exploration Systems Steve Lindsey (who is also a former test pilot and astronaut!) speaks with Lightfoot and Roe about the Dream Chaser Space System simulator.

Lightfoot climbed inside the Dream Chaser simulator where he “flew” the crew version of the spacecraft to a safe landing. This mock-up facility enables approach-and-landing simulations as well as other real-life situations. 

See all the images from the Sierra Nevada visit HERE.

Ball Aerospace

Lightfoot and Roe went over to Ball Aerospace to tour its facility. Ball is another one of our commercial aerospace partners and helps builds instruments that are on NASA spacecraft throughout the universe, including the Hubble Space Telescope and the New Horizons mission to Pluto. Ball designed and built the advanced optical technology and lightweight mirror system that will enable the James Webb Space Telescope to look 13.5 billion years back in time. 

Looking into the clean room at Ball Aerospace’s facility in Boulder, Colo., the team can see the Ozone Mapping Profiler Suite. These sensors are used on spacecraft to track ozone measurements.

Here, the group stands in front of a thermal vacuum chamber used to test satellite optics. The Operation Land Imager-2 is being built for Landsat 9, a collaboration between NASA and the U.S. Geological Survey that will continue the Landsat Program’s 40-year data record monitoring the Earth’s landscapes from space.

See all the pictures from the Ball Aerospace visit HERE. 

We recently marked a decade since a new era began in commercial spaceflight development for low-Earth orbit transportation. We inked agreements in 2006 to develop rockets and spacecraft capable of carrying cargo such as experiments and supplies to and from the International Space Station. Learn more about commercial space HERE.

Is it fun working at NASA?

Living and Working Aboard Station

 Join us on Facebook Live for a conversation with astronaut Kate Rubins and the director of the National Institutes for Health on Tuesday, October 18 at 11:15 a.m. ET.

Astronaut Kate Rubins has conducted out of this world research aboard Earth’s only orbiting laboratory. During her time aboard the International Space Station, she became the first person to sequence DNA in space. On Tuesday, she’ll be live on Facebook with National Institute of Health director Francis Collins, who led the effort to map the human genome. You can submit questions for Kate using the hashtag #SpaceChat on Twitter, or during the live event. Here’s a primer on the science this PhD astronaut has been conducting to help inspire your questions: 

Kate has a background in genomics (a branch of molecular genetics that deals with the study of genomes,specifically the identification and sequencing of their constituent genes and the application of this knowledge in medicine, pharmacy,agriculture, and other fields). When she began her tenure on the station, zero base pairs of DNA had been sequenced in space. Within just a few weeks, she and the Biomolecule Sequencer team had sequenced their one billionth base of DNA aboard the orbital platform.

“I [have a] genomics background, [so] I get really excited about that kind of stuff,” Rubins said in a downlink shortly after reaching the one billion base pairs sequenced goal.

+NASA AMA: We just sequenced DNA in space for the first time. Ask us anything! 

NASA and Its Partnerships

We’re not doing this alone. Just like the DNA sequencing was a collaborative project with industry, so is the Eli Lilly Hard to Wet Surfaces investigation, which is a partnership between CASIS and Eli Lilly Co. In this experiment aboard the station, astronauts will study how certain materials used in the pharmaceutical industry dissolve in water while in microgravity. Results from this investigation could help improve the design of tablets that dissolve in the body to deliver drugs, thereby improving drug design for medicines used in space and on Earth. Learn more about what we and our partners are doing:

Researchers to Test How Solids Dissolve in Space to Design Better Tablets and Pills on Earth

With our colleagues at the Stanford University School of Medicine, we’re also investigating the effects of spaceflight on stem cell-derived heart cells, specifically how heart muscle tissue, contracts, grows and changes  in microgravity and how those changes vary between subjects. Understanding how heart muscle cells change in space improves efforts for studying disease, screening drugs and conducting cell replacement therapy for future space missions. Learn more:

It’s Not Just Medicine

Kate and her crew mates have also worked on the combustion experiments.

Kate has also worked on the Bigelow Expandable Activity Module (BEAM), an experimental expandable capsule that docks with the station. As we work on our Journey to Mars, future space habitats  are a necessity. BEAM, designed for Mars or other destinations, is a lightweight and relatively simple to construct solution. Kate has recently examined BEAM, currently attached to the station, to take measurements and install sensors.

Kate recently performed a harvest of the Plant RNA Regulation experiment, by removing seed cassettes and stowing them in cold stowage.

The Plant RNA Regulation investigation studies the first steps of gene expression involved in development of roots and shoots. Scientists expect to find new molecules that play a role in how plants adapt and respond to the microgravity environment of space, which provides new insight into growing plants for food and oxygen supplies on long-duration missions. Read more about the experiment:

+Plant RNA Harvest

NASA Astronaut Kate Rubins is participating in several investigations examining changes in her body as a result of living in space. Some of these changes are similar to issues experienced by our elderly on Earth; for example, bone loss (osteoporosis), cardiovascular deconditioning, immune dysfunction, and muscle atrophy. Understanding these changes and how to prevent them in astronauts off the Earth may help improve health for all of us on the Earth. In additional, the crew aboard station is also working on more generalized studies of aging.
