A Surprising Surge At Vavilov Ice Cap

13 Reasons to Have an Out of this World Friday (the 13th)

1. Know that not all of humanity is bound to the ground

Since 2000, the International Space Station has been continuously occupied by humans. There, crew members live and work while conducting important research that benefits life on Earth.

2. Smart people are up all night working in control rooms all over NASA to ensure that data keeps flowing from our satellites

Our satellites help scientists study Earth and space. Satellites looking toward Earth provide information about clouds, oceans, land and ice. They also measure gases in the atmosphere, such as ozone and carbon dioxide, and the amount of energy that Earth absorbs and emits. And satellites monitor wildfires, volcanoes and their smoke.

Satellites that face toward space have a variety of jobs. Some watch for dangerous rays coming from the sun. Others explore asteroids and comets, the history of stars, and the origin of planets. Some satellites fly near or orbit other planets. These spacecraft may look for evidence of water on Mars or capture close-up pictures of Saturn’s rings.

3. When we are ready to send humans to Mars, they’ll have the most high tech space suits ever made

Our Z-2 Spacesuit is the newest prototype in its next-generation platform, the Z-series. Each iteration of the Z-series will advance new technologies that one day will be used in a suit worn by the first humans to step foot on the red planet.

4. When we need more space in space, it could be just like expanding a big high-tech balloon

The Bigelow Expandable Activity Module, or BEAM, leverages key innovations in lightweight and compact materials, departing from a traditional rigid metallic structure. Once attached to the International Space Station, the module would result in an additional 565 cubic feet of volume, which is about the size of a large family camping tent.

5. Even astronauts eat their VEGGIE's

The Vegetable Production System (VEGGIE) is a deployable plant growth unit capable of producing salad-type crops in space. Earlier this year, Expedition 44 crew members, sampled the red romaine lettuce from the VEGGIE plant growth system. This technology will provide future pioneers with a sustainable food supplement during long-duration exploration missions.

6. When you feel far away from home, you can think of the New Horizons spacecraft as it heads toward the Kuiper Belt…billions of miles away

Our New Horizons spacecraft completed its Pluto flyby on July 14, and has continued on its way toward the Kuiper Belt. The spacecraft continues to send back important data as it travels toward deeper space at more than 32,000 miles per hour, and is nearly 3.2 billion miles from Earth.

7. Earth has a magnetic field that largely protects it from the solar wind stripping away our atmosphere…unlike Mars

Recently announced findings from our MAVEN mission have identified the process that appears to have played a key role in the transition of the Martian climate from an early, warm and wet environment to the cold, arid planet Mars is today. MAVEN data have enabled researchers to determine the rate at which the Martian atmosphere currently is losing gas to space via stripping by the solar wind. Luckily, Earth has a magnetic field that largely protects it from this process. 

8. Water bubbles look REALLY cool in space

Astronauts on the International Space Station dissolved an effervescent tablet in a floating ball of water, and captured images using a camera capable of recording four times the resolution of normal high-definition cameras. The higher resolution images and higher frame rate videos can reveal more information when used on science investigations, giving researchers a valuable new tool aboard the space station. This footage is one of the first of its kind.

9. Americans will launch from U.S. soil again with the Commercial Crew Program

Our Commercial Crew Program is working with the American aerospace industry as companies develop and operate a new generation of spacecraft and launch systems capable of carrying crews to low-Earth orbit and the International Space Station.

10. You can see a global image of your home planet…EVERY DAY

Once a day, we will post at least a dozen new color images of Earth acquired from 12 to 36 hours earlier. These images are taken by our EPIC camera from one million miles away on the Deep Space Climate Observatory (DSCOVR). Take a look HERE.

11. Over 18,000 people wanted to be astronauts and join us on the journey to Mars

More than 18,300 people applied to join our 2017 astronaut class, almost three times the number of applications received in 2012 for the most recent astronaut class, and far surpassing the previous record of 8,000 in 1978. Among this group are humanities next great explorers!

12. A lot of NASA-developed tech has been transferred for use to the public

Our Technology Transfer Program highlights technologies that were originally designed for our mission needs, but have since been introduced to the public market. HERE are a few spinoff technologies that you might not know about.

13. If all else fails, there’s this image of Psychedelic Pluto

This false color image of Pluto was created using a technique called principal component analysis. This effect highlights the many subtle color differences between Pluto’s distinct regions.

What Space Weather Means for You

In space, invisible, fast-moving particles from the Sun and other sources in deep space zip around, their behavior shaped by dynamic electric and magnetic fields. There are so few of these particles that space is considered a vacuum, but what’s there packs a punch. Together, we call all of this invisible activity space weather — and it affects our technology both in space and here on Earth.

This month, two new missions are launching to explore two different kinds of space weather.

Scrambled signals

Many of our communications and navigation systems — like GPS and radio — rely on satellites to transmit their signals. When signals are sent from satellites down to Earth, they pass through a dynamic zone on the upper edge of Earth's atmosphere called the ionosphere.

Gases in the ionosphere have been cooked into a sea of positive- and negative-charged particles by solar radiation. These electrically charged particles are also mixed in with neutral gases, like the air we breathe. The charged particles respond to electric and magnetic fields, meaning they react to space weather. Regular weather can also affect this part of the atmosphere.

Influenced by this complicated web of factors, structured bubbles of charged gas sometimes form in this part of the atmosphere, particularly near the equator. When signals pass through these bubbles, they can get distorted, causing failed communications or inaccurate GPS fixes.

Right now, it's hard to predict just when these bubbles will form or how they'll mess with signals. The two tiny satellites of the E-TBEx mission will try to shed some light on this question.

As these CubeSats fly around Earth, they'll send radio signals to receiving stations on the ground. Scientists will examine the signals received in order to see whether — and if so, how much — they were jumbled as they traveled through the upper atmosphere and down to Earth.

All together, this information will give scientists a better idea of how these bubbles form and change and how much they disrupt signals — information that could help develop strategies for mitigating these bubbles' disruptive effects.

Damaged satellites

The high-energy, fast-moving particles that fill space are called radiation. Every single spacecraft — from scientific satellites sprinkled throughout the solar system to the communications satellites responsible for relaying the GPS signals we use every day — must weather the harsh radiation of space.

Strikes from tiny, charged particles can spark memory damage or computer upsets on spacecraft, and over time, degrade hardware. The effects are wide-ranging, but ultimately, radiation can impact important scientific data, or prevent people from getting the proper navigation signals they need.

Space Environment Testbeds — or SET, for short — is our mission to study how to better protect satellites from space radiation.

SET aims its sights on a particular neighborhood of near-Earth space called the slot region: the gap between two of Earth’s vast, doughnut-shaped radiation belts, also known as the Van Allen Belts. The slot region is thought to be calmer than the belts, but known to vary during extreme space weather storms driven by the Sun. How much it changes exactly, and how quickly, remains uncertain.

The slot region is an attractive one for satellites — especially commercial navigation and communications satellites that we use every day — because from about 12,000 miles up, it offers not only a relatively friendly radiation environment, but also a wide view of Earth. During intense magnetic storms, however, energetic particles from the outer belt can surge into the slot region. 

SET will survey the slot region, providing some of the first day-to-day weather measurements of this particular neighborhood in near-Earth space. The mission also studies the fine details of how radiation damages instruments and tests different methods to protect them, helping engineers build parts better suited for spaceflight. Ultimately, SET will help other missions improve their design, engineering and operations to avoid future problems, keeping our space technology running smoothly as possible.

A patchwork of bright, criss-crossing cloud trails was created by ships churning through the Atlantic Ocean off the coast of Portugal and Spain in this image captured by one of our Earth observing satellites. The narrow clouds known as ship tracks, form when water vapor condenses around tiny particles of pollution that ships emit.

Some of the pollution particles generated by ships (especially sulfates) are soluble in water and serve as the seeds around which cloud droplets form. Clouds infused with ship exhaust have more and smaller droplets than unpolluted clouds. Because of this, the light hitting the polluted clouds scatters in many directions, making them appear brighter and thicker than unpolluted marine clouds, which are typically seeded by larger, naturally occurring particles such as sea salt.

Flying With Fuel From Plants: The Eco-friendly Way to Go

We eat them. We make medicines out of them. Now we’re learning how to use plants as airplane fuel that helps the environment.

Using biofuels to help power jet engines reduces particle emissions in their exhaust by as much as 50 to 70 percent, according to a new study that bodes well for airline economics and Earth’s atmosphere.

The findings are the result of a cooperative international research program led by NASA and involving agencies from Germany and Canada, and are detailed in a study published in the journal Nature.

Our flight tests collected information about the effects of alternative fuels on engine performance, emissions and aircraft-generated contrails – essentially, human-made clouds - at altitudes flown by commercial airliners. 

The DC-8's four engines burned either JP-8 jet fuel or a 50-50 blend of JP-8 and renewable alternative fuel of hydro processed esters and fatty acids produced from camelina plant oil. Credits: NASA/SSAI Edward Winstead

Contrails are produced by hot aircraft engine exhaust mixing with the cold air that is typical at cruise altitudes several miles above Earth's surface, and are composed primarily of water in the form of ice crystals.

Researchers are interested in contrails because they create clouds that would not normally form in the atmosphere, and are believed to influence Earth’s environment. 

The alternative fuels tested reduced those emissions. That’s important because contrails have a larger impact on Earth’s atmosphere than all the aviation-related carbon dioxide emissions since the first powered flight by the Wright Brothers.

Researchers plan on continuing these studies to understand the benefits of replacing current fuels in aircraft with biofuels.

Great Scott, it’s Back to the Future Day – Oct. 21, 2015

What would a time traveler from 1985 discover about   NASA today?

It’s Back to the Future Day, the date in the second film that Marty and Doc traveled to in the future. When they arrived in 2015, it looked much different than today’s reality. Although we may not have self-drying jackets or flying cars, we do have some amazing spacecraft and technologies that were not around back when the film was made.

For example, in 1985 we did not have the capability to capture an image like this of our Earth. This full-Earth view captured Monday (10/19/15) by our camera on the Deep Space Climate Observatory, or DSCOVER, was not previously possible. The DSCOVR mission captures a daily sequence of images that show the Earth as it rotates, revealing the whole globe over the course of a day. These images will allow scientists to study daily variations over the entire globe in such features as vegetation, ozone, aerosols and cloud height and reflectivity.

So, we might not be cruising down the street on hover boards, but the movies didn’t get it all wrong in terms of how advanced we’d be in 2015.

When you were a kid, what technologies did you dream we’d have in the future that we may or may not have today? Here’s what two astronauts said:

NASA is much different than it was in 1985. Could we have dreamed these amazing accomplishments that have changed our world and understanding of the universe?

1. “There will be an orbiting laboratory where astronauts from around the world will live and work together.”

When Back to the Future II was set, the International Space Station didn’t exist yet. The first piece of the space station was launched in 1998, and the first crew arrived in 2000. Since November 2000, the station has been continuously occupied by humans. 

2. "We will find planets orbiting in the habitable zone of a star, and possibly suited for life."

The first exoplanet, or planet orbiting around a star, was found in 1995. Since then, we’ve discovered around a dozen habitable zone planets in the Earth-size range. While we aren’t able to zoom in to these planets that are light-years away, we’re still closer to finding another Earth-like planet in 2015 than we were in 1985. 

3. “Mars will become more populated.”

No, not by humans...yet. But, since the release of Back to the Future II, Mars has become a bit more populated with rovers and orbiters. These scientific spacecraft have played an important role in learning about the Red Planet. We currently have six missions at Mars. With the most recent news of liquid water on the surface of Mars, we can look forward to future missions returning even more data and images. The historical log of all Mars missions, both domestic and international can be found HERE. 

4. “We will launch a telescope into orbit that’s capable of looking at locations more than 13.4 billion light years from Earth.”

When Back to the Future II was released, our Hubble Space Telescope had not yet launched into orbit -- something that wouldn’t happen until April 1990. Since then, Hubble has made more than 1.2 million observations, and has traveled more than 3 billion miles along a circular low Earth orbit. For updates on Hubble’s findings, check HERE.

What’s Up - June 2018

What’s Up For June?

Jupiter and Venus at sunset, Mars, Saturn and Vesta until dawn.

First up is Venus. It reaches its highest sunset altitude for the year this month and sets more than two hours after sunset.

You can't miss Jupiter, only a month after its opposition--when Earth was directly between Jupiter and the Sun.

The best time to observe Jupiter through a telescope is 10:30 p.m. at the beginning of the month and as soon as it's dark by the end of the month.  

Just aim your binoculars at the bright planet for a view including the four Galilean moons. Or just enjoy Jupiter with your unaided eye!

Saturn is at opposition June 27th, when it and the Sun are on opposite sides of Earth. It rises at sunset and sets at sunrise. Great Saturn viewing will last several more months. The best views this month will be just after midnight.

All year, the rings have been tilted wide open--almost 26 degrees wide this month--giving us a great view of Saturn's distinctive rings.

The tilt offers us a view of the north polar region, so exquisitely imaged by the Cassini spacecraft.

Near Saturn, the brightest asteroid--Vesta--is so bright that it can be seen with your unaided eye. It will be visible for several months.

A detailed star chart will help you pick out the asteroid from the stars. The summer Milky way provides a glittery backdrop.

Finally, Mars grows dramatically in brightness and size this month and is visible by 10:30 p.m. by month end.

The best views are in the early morning hours. Earth's closest approach with Mars is only a month away. It's the closest Mars has been to us since 2003.

Watch the full What’s Up for June Video: 

There are so many sights to see in the sky. To stay informed, subscribe to our What’s Up video series on Facebook. Make sure to follow us on Tumblr for your regular dose of space: http://nasa.tumblr.com.  

How are decisions made about what experiments are sent into space? Are there certain kinds of experiments that NASA wants to conduct every time cargo is launched to the ISS, or are there occasionally experiments that are duplicated for more observation and data collection?

Seeing the Invisible Universe

This computer-simulated image shows a supermassive black hole at the core of a galaxy. The black region in the center represents the black hole’s event horizon, beyond which no light can escape the massive object’s gravitational grip. The black hole’s powerful gravity distorts space around it like a funhouse mirror. Light from background stars is stretched and smeared as it skims by the black hole. You might wonder — if this Tumblr post is about invisible things, what’s with all the pictures? Even though we can’t see these things with our eyes or even our telescopes, we can still learn about them by studying how they affect their surroundings. Then, we can use what we know to make visualizations that represent our understanding.

When you think of the invisible, you might first picture something fantastical like a magic Ring or Wonder Woman’s airplane, but invisible things surround us every day. Read on to learn about seven of our favorite invisible things in the universe!

1. Black Holes

This animation illustrates what happens when an unlucky star strays too close to a monster black hole. Gravitational forces create intense tides that break the star apart into a stream of gas. The trailing part of the stream escapes the system, while the leading part swings back around, surrounding the black hole with a disk of debris. A powerful jet can also form. This cataclysmic phenomenon is called a tidal disruption event.

You know ‘em, and we love ‘em. Black holes are balls of matter packed so tight that their gravity allows nothing — not even light — to escape. Most black holes form when heavy stars collapse under their own weight, crushing their mass to a theoretical singular point of infinite density.

Although they don’t reflect or emit light, we know black holes exist because they influence the environment around them — like tugging on star orbits. Black holes distort space-time, warping the path light travels through, so scientists can also identify black holes by noticing tiny changes in star brightness or position.

2. Dark Matter

A simulation of dark matter forming large-scale structure due to gravity.

What do you call something that doesn’t interact with light, has a gravitational pull, and outnumbers all the visible stuff in the universe by five times? Scientists went with “dark matter,” and they think it's the backbone of our universe’s large-scale structure. We don’t know what dark matter is — we just know it's nothing we already understand.

We know about dark matter because of its gravitational effects on galaxies and galaxy clusters — observations of how they move tell us there must be something there that we can’t see. Like black holes, we can also see light bend as dark matter’s mass warps space-time.

3. Dark Energy

Animation showing a graph of the universe’s expansion over time. While cosmic expansion slowed following the end of inflation, it began picking up the pace around 5 billion years ago. Scientists still aren’t sure why.

No one knows what dark energy is either — just that it’s pushing our universe to expand faster and faster. Some potential theories include an ever-present energy, a defect in the universe’s fabric, or a flaw in our understanding of gravity.

Scientists previously thought that all the universe’s mass would gravitationally attract, slowing its expansion over time. But when they noticed distant galaxies moving away from us faster than expected, researchers knew something was beating gravity on cosmic scales. After further investigation, scientists found traces of dark energy’s influence everywhere — from large-scale structure to the background radiation that permeates the universe.

4. Gravitational Waves

Two black holes orbit each other and generate space-time ripples called gravitational waves in this animation.

Like the ripples in a pond, the most extreme events in the universe — such as black hole mergers — send waves through the fabric of space-time. All moving masses can create gravitational waves, but they are usually so small and weak that we can only detect those caused by massive collisions.  Even then they only cause infinitesimal changes in space-time by the time they reach us. Scientists use lasers, like the ground-based LIGO (Laser Interferometer Gravitational-Wave Observatory) to detect this precise change. They also watch pulsar timing, like cosmic clocks, to catch tiny timing differences caused by gravitational waves.

This animation shows gamma rays (magenta), the most energetic form of light, and elusive particles called neutrinos (gray) formed in the jet of an active galaxy far, far away. The emission traveled for about 4 billion years before reaching Earth. On Sept. 22, 2017, the IceCube Neutrino Observatory at the South Pole detected the arrival of a single high-energy neutrino. NASA’s Fermi Gamma-ray Space Telescope showed that the source was a black-hole-powered galaxy named TXS 0506+056, which at the time of the detection was producing the strongest gamma-ray activity Fermi had seen from it in a decade of observations.

5. Neutrinos

This animation shows gamma rays (magenta), the most energetic form of light, and elusive particles called neutrinos (gray) formed in the jet of an active galaxy far, far away. The emission traveled for about 4 billion years before reaching Earth. On Sept. 22, 2017, the IceCube Neutrino Observatory at the South Pole detected the arrival of a single high-energy neutrino. NASA’s Fermi Gamma-ray Space Telescope showed that the source was a black-hole-powered galaxy named TXS 0506+056, which at the time of the detection was producing the strongest gamma-ray activity Fermi had seen from it in a decade of observations.

Because only gravity and the weak force affect neutrinos, they don’t easily interact with other matter — hundreds of trillions of these tiny, uncharged particles pass through you every second! Neutrinos come from unstable atom decay all around us, from nuclear reactions in the Sun to exploding stars, black holes, and even bananas.

Scientists theoretically predicted neutrinos, but we know they actually exist because, like black holes, they sometimes influence their surroundings. The National Science Foundation’s IceCube Neutrino Observatory detects when neutrinos interact with other subatomic particles in ice via the weak force.

6. Cosmic Rays

This animation illustrates cosmic ray particles striking Earth's atmosphere and creating showers of particles.

Every day, trillions of cosmic rays pelt Earth’s atmosphere, careening in at nearly light-speed — mostly from outside our solar system. Magnetic fields knock these tiny charged particles around space until we can hardly tell where they came from, but we think high energy events like supernovae can accelerate them. Earth’s atmosphere and magnetic field protect us from cosmic rays, meaning few actually make it to the ground.

Though we don’t see the cosmic rays that make it to the ground, they tamper with equipment, showing up as radiation or as “bright” dots that come and go between pictures on some digital cameras. Cosmic rays can harm astronauts in space, so there are plenty of precautions to protect and monitor them.

7. (Most) Electromagnetic Radiation

The electromagnetic spectrum is the name we use when we talk about different types of light as a group. The parts of the electromagnetic spectrum, arranged from highest to lowest energy are: gamma rays, X-rays, ultraviolet light, visible light, infrared light, microwaves, and radio waves. All the parts of the electromagnetic spectrum are the same thing — radiation. Radiation is made up of a stream of photons — particles without mass that move in a wave pattern all at the same speed, the speed of light. Each photon contains a certain amount of energy.

The light that we see is a small slice of the electromagnetic spectrum, which spans many wavelengths. We frequently use different wavelengths of light — from radios to airport security scanners and telescopes.

Visible light makes it possible for many of us to perceive the universe every day, but this range of light is just 0.0035 percent of the entire spectrum. With this in mind, it seems that we live in a universe that’s more invisible than not! NASA missions like NASA's Fermi, James Webb, and Nancy Grace Roman  space telescopes will continue to uncloak the cosmos and answer some of science’s most mysterious questions.

9 Out-of-This-World Moments for Space Communications & Navigation in 2023

How do astronauts and spacecraft communicate with Earth?

By using relay satellites and giant antennas around the globe! These tools are crucial to NASA’s space communications networks: the Near Space Network and the Deep Space Network, which bring back science and exploration data every day.

It’s been a great year for our space communications and navigation community, who work to maintain the networks and enhance NASA’s capabilities. Keep scrolling to learn more about our top nine moments.

The SpaceX Falcon 9 rocket carrying the Dragon spacecraft lifts off from Launch Complex 39A at NASA's Kennedy Space Center in Florida on Thursday, Nov. 9, 2023, on the company's 29th commercial resupply services mission for the agency to the International Space Station. Liftoff was at 8:28 p.m. EST.

1. In November, we launched a laser communications payload, known as ILLUMA-T, to the International Space Station. Now, ILLUMA-T and the Laser Communications Relay Demonstration (LCRD) are exchanging data and officially complete NASA’s first two-way, end-to-end laser relay system. Laser communications can send more data at once than traditional radio wave systems – think upgrading from dial-up to fiber optic internet. ILLUMA-T and LCRD are chatting at 1.2 gigabits per second (Gbps). At that rate, you could download an average movie in under a minute.

NASA’s InSight lander captured this selfie on Mars on April 24, 2022, the 1,211th Martian day, or sol, of the mission.

2. Data analyzed in 2023 from NASA’s retired InSight Mars lander provided new details about how fast the Red Planet rotates and how much it wobbles. Scientists leveraged InSight’s advanced radio technology, upgrades to the Deep Space Network, and radio signals to determine that Mars’ spin rate is increasing, while making the most precise measurements ever of Mars’ rotation.

TBIRD is demonstrating a direct-to-Earth laser communications link from low Earth orbit to a ground station on Earth.

3. We set a new high record! The TeraByte InfraRed Delivery (TBIRD) payload – also demonstrating laser communications like ILLUMA-T and LCRD – downlinked 4.8 terabytes of data at 200 Gbps in a single 5-minute pass. This is the highest data rate ever achieved by laser communications technology. To put it in perspective a single terabyte is the equivalent of about 500 hours of high-definition video.

4. This year we celebrated the Deep Space Network’s 60th anniversary. This international array of antennas located at three complexes in California, Spain, and Australia allow us to communicate with spacecraft at the Moon and beyond. Learn more about the Deep Space Network’s legacy and future advancements.

5. We are bringing humans to the Moon with Artemis missions. During expeditions, astronauts exploring the surface are going to need internet-like capabilities to talk to mission control, understand their routes, and ensure overall safety. The space comm and nav group is working with international partners and commercial companies to develop LunaNet, and in 2023, the team released Draft LunaNet Specification Version 5, furthering development.

The High-Rate Delay Tolerant Networking node launched to the International Space Station in November and will act as a high-speed path for data.

6. In addition to laser communications, ILLUMA-T on the International Space Station is also demonstrating high-rate delay/disruption tolerant networking (HDTN). The networking node is showcasing a high-speed data path and a store-and-forward technique. HDTN ensures data reaches its final destination and isn’t lost on its path due to a disruption or delay, which are frequent in the space environment.

The Communications Services Project (CSP) partners with commercial industry to provide networking options for future spaceflight missions.

7. The space comm and nav team is embracing the growing aerospace industry by partnering with commercial companies to provide multiple networking options for science and exploration missions. Throughout 2023, our commercialization groups engaged with over 110 companies through events, one-on-one meetings, forums, conferences, and more. Over the next decade, NASA plans to transition near-Earth services from government assets to commercial infrastructure.

Middle and high school students solve a coding experiment during NASA's Office of STEM Engagement App Development Challenge. 

8. Every year, NASA’s Office of STEM Engagement sponsors the App Development Challenge, wherein middle and high school students must solve a coding challenge. This year, student groups coded an application to visualize the Moon’s South Pole region and display information for navigating the Moon’s surface. Our space communications and navigation experts judged and interviewed students about their projects and the top teams visited NASA’s Johnson Space Center in Houston!

A SpaceX Falcon 9 rocket soars upward after liftoff at the pad at 3:27 a.m. EDT on Saturday, Aug. 26, from Kennedy Space Center’s Launch Complex 39A in Florida carrying NASA’s SpaceX Crew-7 crew members to the International Space Station. Aboard SpaceX’s Dragon spacecraft are NASA astronaut Jasmin Moghbeli, ESA (European Space Agency) astronaut Andreas Mogensen, JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa, and Roscosmos cosmonaut Konstantin Borisov.

9. The Near Space Network supported 19 launches in 2023! Launches included Commercial Crew flights to the International Space Station, science mission launches like XRISM and the SuperBIT balloon, and many more. Once in orbit, these satellites use Near Space Network antennas and relays to send their critical data to Earth. In 2023, the Near Space Network provided over 10 million minutes of communications support to missions in space.

Here’s to another year connecting Earth and space.
