Video: 00:03:29 Mission complete. ESA’s second European Remote Sensing (ERS-2) satellite has reentered Earth’s atmosphere over the North Pacific Ocean. The satellite returned at 18:17 CET (17:17 UTC) between Alaska and Hawaii.
ERS-2 was launched almost 30 years ago, on 21 April 1995. Together with ERS-1, it provided invaluable long-term data on Earth’s land surfaces, ocean temperatures, ozone layer and polar ice extent that revolutionised our understanding of the Earth system.
ERS-2’s reentry was ‘natural’. ESA used the last of its fuel, emptied its batteries and lowered the satellite from its altitude of 785 km to 573 km. This reduced the risk of collision with other satellites and space debris. As a result, it was not possible to control ERS-2 at any point during its reentry and the only force driving its descent was unpredictable atmospheric drag.
As well as leaving a remarkable legacy of data that still continue to advance science, this outstanding mission set the stage for many of today’s satellites and ESA’s position at the forefront of Earth observation.
The ERS-2 reentry is part of ESA's wider efforts to ensure the long-term sustainability of space activities. These include ESA's Clean Space initiative which promotes the development of new technologies for more sustainable space missions in collaboration with the wider European space community, as well as the Zero Debris Approach, which will even further reduce the debris left in both Earth and lunar orbits by future missions.

Meet the Creators, Part 4: Two New 2024 Total Eclipse Posters
Total solar eclipses reveal the Sun’s outer atmosphere – the corona – a white, wispy halo of solar material that flows out from around the Sun. This atmosphere is breathtaking as it glows in the sky for viewers on Earth, surrounding the dark disk of the Moon. In addition to revealing this normally hidden part of our Sun, the eclipse also darkens the sky, changes shadows, and cools the air. It can feel like living inside a piece of art.
Artists have captured the magical appearance of eclipses for over a thousand years. For the upcoming total solar eclipse crossing North America on April 8, 2024, two artists have contributed new posters to NASA’s eclipse poster series.
Dongjae “Krystofer” Kim
Download the poster here. NASA/Dongjae “Krystofer” Kim Dongjae “Krystofer” Kim is a Senior Science Animator at the Conceptual Image Lab at NASA’s Goddard Space Flight Center. He received a Bachelor of Fine Arts in Design and Technology from Parsons School of Design and a Master of Business Administration and Master of Arts from the Design Leadership program at the Maryland Institute of Contemporary Art and the Johns Hopkins Carey Business School. He combines various art and design disciplines, including fine arts, graphic design, creative coding, animation, and design research to help tell NASA’s story.
Where did you get inspiration for the eclipse poster?
“I was contemplating how the eclipse is an event that is beyond human scale physically and chronologically. It will look differently outside of my myopic view from this planet and it will occur after I am gone for many years to come. With this perspective, I thought of how future space explorations with permanent settlements on the Moon will view this event. While searching for scientific references, I remembered a video piece by our own NASA Goddard media team ‘An EPIC View of the Moon’s Shadow During the June 10 Solar Eclipse’ in 2021 and used it as a visual reference.”
What inspired you to become an artist?
“My inspiration came via Pixar and Ghibli animated films and shows I watched as a child. Despite being a little dyslexic Korean kid, I was welcomed into the world of each story. I found it magical that artists could seemingly create everything from nothing or something fantastical from mundane ideas and objects. And I loved that art enables you to communicate your own ideas as well as learn about others creating common ground.”

Her work has been shown internationally, aired on PBS, and has been featured in many outlets, including The New York Times, Vanity Fair, WIRED, The Atlantic, and National Geographic. She holds a Master of Fine Arts from American University and a Bachelor of Arts from The Ohio State University.
Where did you get inspiration for the eclipse poster?
“During the 2017 total solar eclipse, my parents sent me a picture of themselves, smiling in eclipse glasses and sitting on their front stoop with their dog. It was such a goofy, happy picture, I wanted to capture that same spirit for the poster. I have a dog of my own now – a goofy, happy American foxhound mix – and he proved to be the perfect model for the total eclipse poster. There’s no denying an eclipse can be an awe-inspiring event, but it can be just plain fun too!”
What inspired you to become an artist?
“I can’t help it! I’ve always made things, and I’ve been very fortunate to have had support along the way. My parents enrolled me in my first art class at four, and they encouraged me to submit work to art contests all through elementary and high school. Portfolio-based scholarships and commissioned portrait work helped me pay for college. To this day, I’m incredibly lucky to have had a career where I can be creative, and I am thankful for all the people who have made it possible.”

Teams at NASA’s Stennis Space Center install a new RS-25 engine nozzle in early February in preparation for continued testing on the Fred Haise Test Stand. NASA is conducting a series of tests to certify production of new RS-25 engines for future (Space Launch System) missions, beginning with Artemis V.NASA/Danny Nowlin NASA will conduct an RS-25 hot fire Friday, Feb. 23, moving one step closer to production of new engines that will help power the agency’s SLS (Space Launch System) rocket on future Artemis missions to the Moon and beyond.
Teams at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, are set to begin the second half of a 12-test RS-25 certification series on the Fred Haise Test Stand, following installation of a second production nozzle on the engine.

NASA is conducting a series of tests to certify production of new RS-25 engines for future (Space Launch System) missions, beginning with Artemis V.NASA/Danny Nowlin The six remaining hot fires are part of the second, and final, test series collecting data to certify an updated engine production process, using innovative manufacturing techniques, for lead engines contractor Aerojet Rocketdyne, an L3Harris Technologies company.
As NASA aims to establish a long-term presence on the Moon for scientific discovery and exploration, and prepare for future missions to Mars, new engines will incorporate dozens of improvements to make production more efficient and affordable while maintaining high performance and reliability.
Four RS-25 engines, along with a pair of solid rocket boosters, launch NASA’s powerful SLS rocket, producing more than 8.8 million pounds of thrust at liftoff for Artemis missions.
During the seventh test of the 12-test series, operators plan to fire the certification engine for 550 seconds and up to a 113% power level.
“NASA’s commitment to safety and ‘testing like you fly’ is on display as we plan to fire the engine beyond 500 seconds, which is the same amount of time the engines must fire to help launch the SLS rocket to space with astronauts aboard the Orion spacecraft,” said Chip Ellis, project manager for RS-25 testing at Stennis.
The Feb. 23 test features a second certification engine nozzle to allow engineers to gather additional performance data on the upgraded unit. The new nozzle was installed on the engine earlier this month while it remained at the test stand. Using specially adapted procedures and tools, the teams were able to swap out the nozzles with the engine in place.

NASA is conducting a series of tests to certify production of new RS-25 engines for future (Space Launch System) missions, beginning with Artemis V.NASA/Danny Nowlin In early February 2024, teams at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, completed an RS-25 nozzle remove-and-replace procedure as part of an ongoing hot fire series on the Fred Haise Test Stand. The new nozzle will allow engineers to collect and compare performance data on a second production unit. The RS-25 nozzle, which directs engine thrust, is the most labor-intensive component on the engine and the hardest to manufacture, said Shawn Buckley, Aerojet Rocketdyne’s RS-25 nozzle integrated product team lead.
Aerojet Rocketdyne has focused on streamlining the nozzle production process. Between manufacture of the first and second production units, the company reduced hands-on labor by 17%.
“The nozzle is a work of machinery and work of art at the same time,” Buckley said. “Our team sees this nozzle as more than a piece of hardware. We see the role we play in the big picture as we return humans to the Moon.”
With completion of the certification test series, all systems will be “go” to produce the first new RS-25 engines since the space shuttle era. NASA has contracted with Aerojet Rocketdyne to produce 24 new RS-25 engines using the updated design for missions beginning with Artemis V. NASA and Aerojet Rocketdyne modified 16 former space shuttle missions for use on Artemis missions I through IV.
Through Artemis, NASA will establish the foundation for long-term scientific exploration at the Moon, land the first woman, first person of color, and first international partner astronaut on the lunar surface, and prepare for human expeditions to Mars for the benefit of all.

Video: 00:15:00 Tracking ice lost from the world’s glaciers, ice sheets and frozen land shows that Earth is losing ice at an accelerating rate. Monitoring the cryosphere is crucial for assessing, predicting and adapting to climate change.
The Copernicus Polar Ice and Snow Topography Altimeter (CRISTAL) mission will provide a full picture of the changes taking place in some of the most inhospitable regions of the world. It will carry – for the first time – a dual-frequency radar altimeter, and microwave radiometer, that will measure and monitor sea-ice thickness, overlying snow depth and ice-sheet elevations.
These data will support maritime operations in the polar oceans and contribute to a better understanding of climate processes. CRISTAL will also support applications related to coastal and inland waters, as well as providing observations of ocean topography.
CRISTAL is one of six Copernicus Sentinel Expansion missions that ESA is developing on behalf of the EU. The missions will expand the current capabilities of the Copernicus Space Component – the world’s biggest supplier of Earth observation data.
This video features interviews with Kristof Gantois, CRISTAL Project Manager and Paolo Cipollini, CRISTAL Mission Scientist.
