A decade ago, on Sept. 21, 2014, NASA’s MAVEN (Mars Atmospheric and Volatile EvolutioN) spacecraft entered orbit around Mars, beginning its ongoing exploration of the Red Planet’s upper atmosphere. The mission has produced a wealth of data about how Mars’ atmosphere responds to the Sun and solar wind, and how these interactions can explain the loss of the Martian atmosphere to space.
During its first 10 years at Mars, MAVEN has helped to explain how the Red Planet evolved from warm and wet early on into the cold, dry world that we see today.

“It is an incredibly exciting time for the MAVEN team as we celebrate 10 years of Martian science and see the tremendous impact this mission has had on the field,” said Shannon Curry, the principal investigator of MAVEN and a researcher at the Laboratory for Atmospheric and Space Physics at the University of Colorado Boulder. “We also look forward to the future discoveries MAVEN will bring.”
In celebration of this mission milestone, we recap some of the most significant scientific results of this unique and long-lasting Mars aeronomy mission.
Extreme atmospheric erosion
One of MAVEN’s first big results was discovering that the erosion of Mars’ atmosphere increases significantly during solar storms. The team studied how the solar wind — a stream of charged particles continually streaming from the Sun — and solar storms continually strip away Mars’ atmosphere, and how this process played a key role in altering the Martian climate from a potentially habitable planet to today’s cold, arid planet. Sputtering to space
To better understand how Mars lost much of its atmosphere, MAVEN measured isotopes of argon gas in the upper Martian atmosphere. Argon is a noble gas, meaning it rarely reacts with other constituents in the Martian atmosphere. The only way it can be removed is by atmospheric sputtering — a process where ions crash into the Martian atmosphere at high enough speeds that they knock gas molecules out of the atmosphere. When the MAVEN team analyzed argon isotopes in the upper atmosphere, they were able to estimate that roughly 65% of the argon originally present had been lost through sputtering over the planet’s history. A new type of aurora
MAVEN has discovered several types of auroras that flare up when energetic particles plunge into the atmosphere, bombarding gases and making them glow. The MAVEN team showed that protons, rather than electrons, create auroras at Mars. On Earth, proton auroras only occur in very small regions near the poles, whereas at Mars they can happen everywhere. Martian dust storm
In 2018, a runaway series of dust storms created a dust cloud so large that it enveloped the planet. The MAVEN team studied how this “global” dust storm affected Mars’ upper atmosphere to understand how these events affect how the escape of water to space. It confirmed that heating from dust storms can loft water molecules far higher into the atmosphere than usual, leading to a sudden surge in water lost to space. Map of Martian winds
MAVEN researchers created the first map of wind circulation in the upper atmosphere of Mars. The new map is helping scientists better understand the Martian climate, including how terrain on the planet’s surface is disturbing high-altitude wind currents. The results provide insight into how the dynamics of the upper Martian atmosphere have influenced the Red Planet’s climate evolution in the past and present. Twisted tail
Mars has an invisible magnetic “tail” that is twisted by its interaction with the solar wind. Although models predicted that magnetic reconnection causes Mars’ magnetotail to twist, it wasn’t until MAVEN arrived that scientists could confirm that the predictions were correct. The process that creates the twisted tail could also allow some of Mars’ already thin atmosphere to escape to space. Mapping electric currents
Researchers used MAVEN data to create a map of electric current systems in the Martian atmosphere. These form when solar wind ions and electrons smash into the planet’s induced magnetic field, causing the particles to flow apart. The resulting electric currents, which drape around the planet, play a fundamental role in the atmospheric loss that transformed Mars from a world that could have supported life to an inhospitable desert. Disappearing solar wind
MAVEN recently observed the unexpected “disappearance” of the solar wind. This was caused by a type of solar event so powerful that it created a void in its wake as it traveled across the solar system. MAVEN’s measurements showed that when it reached Mars, the solar wind density dropped significantly. This disappearance of the solar wind allowed the Martian atmosphere and magnetosphere to balloon out by thousands of kilometers. Ultraviolet views of the Red Planet
MAVEN captured stunning views of Mars in two ultraviolet images taken at different points along the Red Planet’s orbit around the Sun. By viewing the planet in ultraviolet wavelengths, scientists gain insight into the Martian atmosphere and view surface features in remarkable ways. Mars’ response to solar storms
In May 2024, a series of solar events triggered a torrent of energetic particles that quickly traveled to Mars. Many of NASA’s Mars missions, including MAVEN, observed this celestial event and captured images of glowing auroras over the planet. MAVEN’s principal investigator is based at the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder. LASP is also responsible for managing science operations and public outreach and communications. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the MAVEN mission. Lockheed Martin Space built the spacecraft and is responsible for mission operations. NASA’s Jet Propulsion Laboratory in Southern California provides navigation and Deep Space Network support.

Organized by the Science Mission Directorate’s Science Support Office (SSO), NASA hosted its 12th annual Earth Day Celebration event from April 18–19, 2024. For the first time ever, the two-day event was held at NASA Headquarters (HQ) in Washington, DC.
The in-person event, which was free and open to the public, featured the newly installed Earth Information Center (EIC) exhibit – see Photos 1–4. The event featured 17 hands-on activities offered in NASA HQ’s East Lobby as well as two adjacent outdoor tents. Event participants were given an activity passport called the “Passport to Fun” listing all the activities and encouraging attendees to visit the stations and interact with NASA staff – see Figure 1. After completing six or more activities, attendees were able to claim giveaway items, e.g., lenticulars, NASA bags, posters, and calendars.

Figure credit: NASA Prior to the event, Trena Ferrell [GSFC—Earth Science Education and Public Outreach Lead] arranged for groups of students from several local schools to visit the NASA Earth Day event. This included over 300 students from DuVal High School, Morgan State University, Howard University, Prince George’s County Environmental Academy, Prince George’s County Virtual Academy, International Hispanic School, and homeschoolers. On April 19, all of the students who were present at that time gathered for a plenary in the Webb Auditorium. Ferrell welcomed the attendees and provided introductions to prepare them for a virtual presentation by former NASA astronaut Paul Richards, who interacted with attendees and answered questions for roughly 20 minutes.
After Richard’s presentation, the attendees heard from Karen St. Germain [NASA HQ—Director of NASA’s Earth Science Division], whose in-person remarks emphasized to the students the crucial albeit less publicized studies that NASA does of our home planet. Related to this year’s Earth Day theme, “Water Touches Everything,” she discussed the ability of NASA’s Earth observing satellites to track water in all its forms as it circulates throughout the Earth system. St. Germain then answered questions from the audience for 15 minutes – see Photos 5–8.

Throughout the two-day event, it is estimated that as many as 1500 public participants attended along with the 300 students already discussed. While SSO staff distributed 500 activity passports, many small groups and families shared a single passport. SSO staff estimates that the true number of participants may be close to 1500 – see Photos 11–19.

Conclusion
NASA’s first Earth Day Celebration at NASA Headquarters was quite successful. While attendance was lower than previous events held at the more heavily trafficked Union Station or the National Mall, there was a steady stream of people throughout the exhibit on both days. It was also a great opportunity to showcase the new EIC to the public. Earth Day is the largest event organized annually by the SSO. This event requires months of planning, cross-divisional coordination, and intensive design of the hands-on activities – all carried from conceptualization through numerous revisions to implementation by more than 100 individuals from across the agency. This combined effort of SSO staff and assisting organizations results in an event that brings together thousands of visitors from a broad spectrum of ages and backgrounds to enjoy NASA science. This event would not have been possible were it not for the incredible efforts and collaboration put forth by so many of NASA’s outreach professionals. The SSO is grateful for all who helped to make this year’s Earth Day event a success and looks forward to Earth Day 2025.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Research pilot Greg Slover “spreads his wings” at NASA’s Langley Research Center. On August 19, tag your posts with #SpreadYourWings or #NationalAviationDay.NASA / David C. Bowman It was in 1939 that President Franklin D. Roosevelt issued the first presidential proclamation designating Aug. 19 – Orville Wright’s birthday – as a day in which citizens are encouraged to participate in activities that promote interest in aviation. So how will you be a good citizen and observe the day as indicated by the President? Here are ten suggestions — plus one bonus idea at the end that is a “must do!” — for you and your family and friends to consider:
1. “Spread Your Wings.”
Have someone take a picture of you and your friends or loved ones stretching out your arms like the wings of an airplane. (For extra brownie points use your hands to make winglets – one of NASA’s many contributions to aviation.) Tell us how you’re celebrating flight on August 19. Post your photo to X, Facebook, Instagram, or any other social media. Be sure and tag it with #NationalAviationDay so we see it!
2. Remember that NASA is with you when you fly.
Are you traveling by air today or anytime soon? After you settle into your assigned seat buckle up, make sure your seatback and folding tray are in their full upright positions, and then take a moment and think about NASA. Why? Well it might not be immediately visible to you, but every U.S. aircraft and air traffic control tower in operation today uses some kind of NASA-developed technology.
Before you take off and the pilots shut the door, glance into the cockpit. See all the electronic displays? They make up what’s called the “glass cockpit.” NASA did early testing on using the displays to replace heavier and outdated dials and gauges.
Now, look out your window. See the vertical extension on the tip of your airplane’s wing? That’s a “winglet.” It was originally tested and developed by NASA as a way to reduce drag. In use for many, many years now, winglets have saved billions of gallons of fuel, according to industry. And they even reduce aircraft noise a bit.
Then there are the things you won’t see. It may be a piece of technology buried deep within your jet engine to help it run more efficiently, or it could be computer software installed in air traffic control centers to help controllers manage your flight, gate-to-gate, more efficiently with reduced delays, all in a way that’s more sustainable and friendly to our planet Earth.
3. Visit your local science museum or NASA visitor center.
Exhibits about aviation and on how an airplane flies are popular staples of local science museums. Check out your local science center to see if they’re open and if they have any exhibits on aviation. And even if they don’t, it never hurts to spend some time learning about science.
And if you live within a short drive from Norfolk, VA; Cleveland, OH; or San Francisco, CA, you might consider checking out the visitors centers associated with NASA’s Langley Research Center, Glenn Research Center, or Ames Research Center, respectively. These major NASA field centers play host to the majority of NASA’s aeronautics research. (NASA’s Armstrong Flight Research Center, the fourth of NASA’s aeronautics centers, is located within the restricted area of Edwards Air Force Base, CA, so they do not have a public visitor’s center.)
4. Watch an aviation-themed movie.
There’s no shortage of classic aviation-themed movies available to watch in whatever format (DVD, streaming online, in the theater, etc.), from whatever source (Red Box, Netflix, your own library, etc.), and with whatever snacks (popcorn, nachos, Sno-Caps, etc.) are your favorite.
We dare not attempt a comprehensive list because we wouldn’t be able to satisfy everyone’s tastes, but a few NASA aeronautics staff favorites include Jimmy Stewart’s “The Spirit of St. Louis” and “Strategic Air Command,” John Wayne’s “Jet Pilot” (featuring the last time Chuck Yeager flew the X-1 rocket plane), National Geographic’s “Living in the Age of Airplanes,” and Disney’s animated “Planes.” Movies that combine aviation and space can be fun, such as “The Right Stuff” or the documentary “One More Orbit,” which tells how former NASA astronaut Terry Virts attempts to break the speed record for circling Earth over the poles in a business jet.
5. Take an introductory flight lesson.
Pilots will tell you there is a wonderful sense of freedom in flying, not to mention the incredible views and the personal sense of accomplishment that comes from mastering the skills required to fly. At the same time being a pilot is not for everyone – but you won’t know unless you try!
Most general aviation airports in the nation have a flight school that offers an introductory flight lesson at a discounted price. Many airports have flying clubs that will introduce you to flight. You also might check to see if there is a Civil Air Patrol in your area.
And if you want a taste of flight from the cockpit without leaving the ground, commercial computer desktop flight simulators such as X-Plane or Microsoft’s Flight Simulator are popular choices and can get you into the virtual sky in short order.
6. Build an airplane
Why not? It doesn’t have to be big enough to actually fly in – although homebuilt airplane kits are available if you have the money, time and perseverance to complete the job.
Putting together a smaller plastic model kit of one of the world’s most historic aircraft can be just as rewarding and just as educational, especially for younger kids who might be thinking about a career as an engineer or aerospace technician.
In fact, many astronauts will tell you their love of aviation and space began with putting models together as a child. Another idea: Grab some LEGO bricks and build the airplane of your dreams, or perhaps one based on real NASA work like these folks did.
Or make it easy on yourself: fold a paper airplane like this one of NASA’s X-59 Quiet SuperSonic Technology aircraft and shoot it across the room. Sometimes simple works best.
7. Tell us about your first flight
Ten years ago, for National Aviation Day in 2014, we asked some fellow NASA workers for stories about their first flights. We received some great ones, and we’d love to hear from you about the first time you ever flew in a plane. Post your story online and be sure to use #NationalAviationDay so we find you. Tell us about the first time you took to the air. Where were you traveling? Why? Do you remember what kind of airplane it was? Were you thrilled, or a little scared? Let us know!
8. Follow what we’re doing to transform aviation.
NASA’s aeronautical innovators are working to transform air transportation to meet the future needs of the global aviation community. Sounds like a big job, right? It is and there are many ways in which NASA is doing this. Improving an airplane’s aerodynamics, reducing the amount of fuel used by airplanes, making airplanes of all sizes quieter, decreasing the amount of harmful emissions released into the atmosphere, working with the Federal Aviation Administration to improve the efficiency of air traffic control – the list could go on for many thousands of more words. Bookmark our NASA Aeronautics home page and follow us on Twitter @NASAaero.
There’s also some great education resources that not only help you learn about NASA’s aeronautics research, but about aviation in general. Visit our Aeronautics STEM page to download activities, fact sheets, coloring pages for kids, and much more. Even more fun things to do at home can be found here.
9. Visit your local library or download a NASA e-book
Aviation-themed books, whether fact or fiction, are all over the shelves of your local library – literally. That’s because there’s no single Dewey Decimal number for aviation. A book about aviation history will be in a different section of the library than a book about how to design an airplane. And fictional books such as the Arthur Hailey classic “Airport,” or autobiographies such as Chuck Yeager’s “Yeager,” are off on yet another shelf. Don’t hesitate to ask your reference librarian for help. And when you get back from the library, or while still there, jump online and check out the NASA e-books you can download and own for free.
10. Have a plane spotting picnic near an airport.
At Washington DC’s Ronald Reagan airport it’s Gravelly Point. In Minneapolis it’s a new viewing location right in the middle of the airport. If you live near a major international airport, chances are you know the best place where the locals can go to watch aircraft take off and land. Be sure to take heed of any security restrictions about where you can and can’t go.
But once you have your spot picked out then load up your picnic basket with lots of goodies and camp out next to the airport for an afternoon of plane spotting. See how many different types of airplanes you can count or identify. For a truly up-close and personal experience, bring a scanner radio and listen in on air traffic control. Helpful plane spotting tips, as well as livestreams of airport activity, are easily found online with the help of your favorite search engine.
BONUS IDEA: Get to Know our Faces of Flight
NASA / Maria Werries In honor of National Aviation Day, we’ve put together a collection of pictures, videos, and stories that showcase some of NASA Aeronautics’ aeronautical innovators who are working to safely transform aviation for the 21st century. See, watch, and read their stories with this up close and personal look,
Enjoy this special feature here!

Each Aug. 4, Coast Guard Day commemorates the founding on Aug. 4, 1790, of the U.S. Coast Guard as the Revenue-Marine by Secretary of the Treasury Alexander Hamilton. Although considered an internal event for active duty and reserve Coast Guard members, we take the opportunity of Coast Guard Day to honor the astronauts who began their careers in the Coast Guard. To date, NASA has selected three astronauts who served in the Coast Guard: Bruce E. Melnick in 1987, Daniel C. Burbank in 1996, and Andre Douglas in 2021. While Melnick and Burbank have retired from NASA, the decades long relationship between the agency and the Coast Guard carries on with Douglas.

Under the guidance of Treasury Secretary Hamilton, the U.S. Congress authorized the establishment of the Revenue-Marine on Aug. 4, 1790. The bill also authorized the building of a fleet of 10 Revenue Service ships known as cutters, used to enforce tariff laws established by Congress. By the 1860s, the organization’s name had changed to the U.S. Revenue Cutter Service. On Jan. 28, 1915, President Woodrow Wilson signed into law an act of Congress that merged the Revenue Cutter Service with the U.S. Life Saving Service, naming the new organization the U.S. Coast Guard, dedicated to saving lives at sea and enforcing the nation’s maritime laws. After 177 years in the Treasury Department, the Coast Guard transferred to the newly formed Department of Transportation on April 1, 1967, and then to the Department of Homeland Security on March 1, 2003.
Bruce E. Melnick

Melnick, a native of Florida, earned a bachelor’s degree in engineering with honors from the U.S. Coast Guard Academy in 1972. During his 20-year career with the U.S. Coast Guard, Melnick’s assignments included serving as operations officer and chief test pilot at the Coast Guard Aircraft Program Office in Grand Prairie, Texas. During his Coast Guard service, Melnick received numerous awards, including two Department of Defense Distinguished Service Medals, two Distinguished Flying Crosses and the Secretary of Transportation Heroism Award. In 1992, he received the U.S. Coast Guard Academy Distinguished Alumni Award. He logged over 5,000 flight hours.. NASA selected Melnick in June 1987 as the first astronaut from the Coast Guard. He completed his training in August 1988, and flew as a mission specialist on Discovery’s STS-41 mission in October 1990. During the four-day flight, he and his crewmates deployed the Ulysses spacecraft to study the Sun’s polar regions. On his second and final spaceflight in May 1992, he served as the flight engineer on STS-49, the first flight of Endeavour. During that mission, the astronauts rescued and repaired the Intelsat VI satellite. He logged more than 300 hours in space. Melnick retired from the U.S. Coast Guard and NASA in July 1992.
Daniel C. Burbank

Middle right: Burbank performs a spacewalk during STS-115. Right: Burbank conducts a pulmonary function study while exercising on the bicycle ergometer in the Destiny module during Expedition 30.
Connecticut-born and Massachusetts native, Burbank received a Bachelor of Science degree in electrical engineering and his commission from the U.S. Coast Guard Academy in May 1985. After attending naval flight training in Pensacola, Florida, he was assigned to Coast Guard Air Station Elizabeth City, North Carolina. In July 1992, Burbank transferred to Coast Guard Air Station Cape Cod, Massachusetts, followed by his assignment in May 1995 to Coast Guard Air Station Sitka, Alaska. Burbank logged over 4,000 flight hours, primarily in Coast Guard helicopters, and flew more than 2,000 missions, including over 300 search and rescue missions. NASA selected Burbank as an astronaut in the class of 1996. During his first spaceflight, the 12-day STS-106 International Space Station assembly mission in September 2000, Burbank and his crewmates prepared the station for the arrival of its first expedition crew. They delivered more than three tons of supplies and installed batteries, power converters, oxygen generation equipment, and a treadmill. He flew his second spaceflight aboard Atlantis in September 2006 on the 12-day STS-115 space station assembly mission. The astronauts delivered and installed the P3/P4 truss and solar arrays, and Burbank took part in one the three spacewalks of the mission, spending 7 hours 11 minutes outside. He flew his third and final mission between November 2011 and April 2012 as a member of Expeditions 29 and 30, serving as Commander of Expedition 30. During the 165-day flight, Burbank and his crewmates participated in nearly 200 experiments and completed 23 major hardware upgrades to the station. During his three missions, Burbank accumulated more than 188 days in space. He retired from NASA in June 2018.
Andre Douglas

Douglas, a Virginia native and 2008 U.S. Coast Guard Academy graduate, served as an active-duty Coast Guard officer from 2008 to 2015. He earned a master’s degree in mechanical engineering and in naval architecture and marine engineering from the University of Michigan, a master’s degree in electrical and computer engineering from Johns Hopkins University and a doctorate in systems engineering from George Washington University. NASA selected Douglas as an astronaut candidate in December 2021, and he completed his training on March 5, 2024. On March 19, the U.S. Coast Guard swore-in Douglas as a commander in the Coast Guard Reserve during a commissioning ceremony in Washington, D.C. On July 3, 2024, NASA named Douglas as a backup crew member for the Artemis II mission to circle the Moon.

The distorted spiral galaxy at center, the Penguin, and the compact elliptical at left, the Egg, are locked in an active embrace. This near- and mid-infrared image combines data from NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument), and marks the telescope’s second year of science. Webb’s view shows that their interaction is marked by a glow of scattered stars represented in blue. Known jointly as Arp 142, the galaxies made their first pass by one another between 25 and 75 million years ago, causing “fireworks,” or new star formation, in the Penguin. The galaxies are approximately the same mass, which is why one hasn’t consumed the other.NASA, ESA, CSA, STScI To celebrate the second science anniversary of NASA’s James Webb Space Telescope, the team has released a near- and mid-infrared image on July 12, 2024, of two interacting galaxies: The Penguin and the Egg.
Webb specializes in capturing infrared light – which is beyond what our own eyes can see – allowing us to view and study these two galaxies, collectively known as Arp 142. Their ongoing interaction was set in motion between 25 and 75 million years ago, when the Penguin (individually cataloged as NGC 2936) and the Egg (NGC 2937) completed their first pass. They will go on to shimmy and sway, completing several additional loops before merging into a single galaxy hundreds of millions of years from now.
