Video: 00:00:00 ESA’s state-of-the-art Biomass satellite launched aboard a Vega-C rocket from Europe’s Spaceport in Kourou, French Guiana. The rocket lifted off on 29 April 2025 at 11:15 CEST (06:15 local time).
In orbit, this latest Earth Explorer mission will provide vital insights into the health and dynamics of the world’s forests, revealing how they are changing over time and, critically, enhancing our understanding of their role in the global carbon cycle. It is the first satellite to carry a fully polarimetric P-band synthetic aperture radar for interferometric imaging. Thanks to the long wavelength of P-band, around 70 cm, the radar signal can slice through the whole forest layer to measure the ‘biomass’, meaning the woody trunks, branches and stems, which is where trees store most of their carbon.
Vega-C is the evolution of the Vega family of rockets and delivers increased performance, greater payload volume and improved competitiveness.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s annual Student Launch challenge will bring middle school, high school, and college students from around the country together to launch high-powered rockets and payloads. On Saturday, May 3, from 8:30 a.m.-2:30 p.m. CDT (or until the last rocket launches), student teams will convene for the agency’s 25th annual challenge at Bragg Farms in Toney, Alabama, near NASA’s Marshall Space Flight Center in Huntsville.
Hundreds of students from across the U.S. and Puerto Rico launched amateur rockets near NASA’s Marshall Space Flight Center in Huntsville, Alabama, during the Agency’s 2024 Student Launch competition. NASA Live streaming will begin at 8:20 a.m. CDT on NASA Marshall YouTube.
Media interested in covering Student Launch events should contact Taylor Goodwin at 938-210-2891.
Winners will be announced June 9 during a virtual awards ceremony once all teams’ flight data has been verified.
Seventy-one teams participated this year; 47 teams are expected to launch in-person. Teams not traveling to Alabama are allowed to conduct final test flights at a qualified launch field near them.
Schedule of Events:
Rocket Fair: Friday, May 2, 2025, 3-6 p.m. at the Von Braun Center East Hall.
A free event for the public to view rockets and meet the student teams.
Launch Day: Saturday, May 3, 2025, gates open at 7 a.m. and the event runs from 8:30 a.m.-2:30 p.m. (or until last rocket launch) at Bragg Farms, in Toney, Alabama. This is a free public event with live rocket launches. Please be weather aware. Lawn chairs are recommended. Pets are not permitted.
Back-up Launch Day: Sunday, May 4, 2025, is reserved as a back-up launch day in case of inclement weather. If needed, the event will run from 8:30 a.m. to 2:30 p.m. (or until last rocket launches) at Bragg Farms.
About the Competition
Student Launch provides relevant, cost-effective research and development of rocket propulsion systems and reflects the goals of NASA’s Artemis Program, which will establish the first long-term presence on the Moon and pave the way for eventual Mars missions.
Each year, the payload component changes to reflect current NASA missions. As Student Launch celebrates its 25th anniversary, the payload challenge will include “reports” from STEMnauts, non-living objects representing astronauts. The STEMnaut “crew” must relay real-time data to the student team’s mission control, just as the Artemis astronaut crew will do as they explore the lunar surface.
Eligible teams compete for prizes and awards and are scored in nearly a dozen categories including safety, vehicle design, social media presence, and science, technology, engineering, and math (STEM) engagement.
Marshall’s Office of STEM Engagement hosts Student Launch to encourage students to pursue careers in STEM through real-world experiences. Student Launch is a part of the agency’s Artemis Student Challenges– a variety of activities exposing students to the knowledge and technology required to achieve the goals of the Artemis missions.
In addition to the NASA Office of STEM Engagement’s Next Gen STEM project, NASA Space Operations Mission Directorate, Northrup Grumman, National Space Club Huntsville, American Institute of Aeronautics and Astronautics, National Association of Rocketry, Relativity Space and Bastion Technologies provide funding and leadership for the competition.

Help Classify Galaxies Seen by NASA’s James Webb Space Telescope!
The Galaxy Zoo classification interface shows you an image from NASA’s Webb telescope and asks you questions about it. Image credit: Galaxy Zoo, Zooniverse. Inset galaxy: NASA/STScI/CEERS/TACC/S. Finkelstein/M. Bagley/Z. Levay/A. Pagan NASA needs your help identifying the shapes of thousands of galaxies in images taken by our James Webb Space Telescope with the Galaxy Zoo project. These classifications will help scientists answer questions about how the shapes of galaxies have changed over time, what caused these changes, and why. Thanks to the light collecting power of Webb, there are now over 500,000 images of galaxies on website of the Galaxy Zoo citizen science project—more images than scientists can classify by themselves.
“This is a great opportunity to see images from the newest space telescope,” said volunteer Christine Macmillan from Aberdeen, Scotland. “Galaxies at the edge of our universe are being seen for the first time, just as they are starting to form. Just sign up and answer simple questions about the shape of the galaxy that you are seeing. Anyone can do it, ages 10 and up!”
As we look at more distant objects in the universe, we see them as they were billions of years ago because light takes time to travel to us. With Webb, we can spot galaxies at greater distances than ever before. We’re seeing what some of the earliest galaxies ever detected look like, for the first time. The shapes of these galaxies tell us about how they were born, how and when they formed stars, and how they interacted with their neighbors. By looking at how more distant galaxies have different shapes than close galaxies, we can work out which processes were more common at different times in the universe’s history.
At Galaxy Zoo, you’ll first examine an image from the Webb telescope. Then you will be asked several questions, such as ‘Is the galaxy round?’, or ‘Are there signs of spiral arms?’. If you’re quick, you may even be the first person to see the galaxies you’re asked to classify.
“I’m amazed and honored to be one of the first people to actually see these images! What a privilege!” said volunteer Elisabeth Baeten from Leuven, Belgium.
Galaxy Zoo is a citizen science project with a long history of scientific impact. Galaxy Zoo volunteers have been exploring deep space since July 2007, starting with a million galaxies from a telescope in New Mexico called the Sloan Digital Sky Survey and then, moving on to images from space telescopes like NASA’s Hubble Space Telescope and ESA (European Space Agency)’s Euclid telescope. The project has revealed spectacular mergers, taught us about how the black holes at the center of galaxies affect their hosts, and provided insight into how features like spiral arms form and grow.
Now, in addition to adding new data from Webb, the science team has incorporated an AI algorithm called ZooBot, which will sift through the images first and label the ‘easier ones’ where there are many examples that already exist in previous images from the Hubble Space Telescope. When ZooBot is not confident on the classification of a galaxy, perhaps due to complex or faint structures, it will show it to users on Galaxy Zoo to get their human classifications, which will then help ZooBot learn more. Working together, humans and AI can accurately classify limitless numbers of galaxies. The Galaxy Zoo science team acknowledges support from the International Space Sciences Institute (ISSI), who provided funding for the team to get together and work on Galaxy Zoo.
