Envisat_20_years_after_launch_card_full. Video: 00:04:00

Twenty years ago, on the first of March 2002, ESA launched a new satellite to monitor our planet from space: Envisat. This research mission, which carried 10 instruments, would become a beacon for the development of future Earth observation satellites. In orbit for 10 years, double its projected lifespan, this flagship mission provided science with a wealth of data on the health of our planet and climate change – a treasure trove of data that is still used today. Thanks to the Heritage Space Programme, ESA ensures these precious data are preserved and made accessible for future generations.

This report includes interviews with :

- Simonetta Cheli, Director of Earth Observation, ESA–ESRIN, Frascati, Italy in English, French & Italian

- Henri Laur, Former Envisat Mission Manager, ESA–ESRIN, Frascati, Italy in English & French

      Sols 4525-4526: The Day After Groundhog Day (Between Ghost Mountain and Texoli, Headed South)
      NASA’s Mars rover Curiosity acquired this image showing ChemCam/Mastcam targets “Breeze Hill” and “Laguna Mountain,” together with a rover wheel planted firmly on the Martian surface. Curiosity captured the image using its Left Navigation Camera on April 27, 2025 — Sol 4523, or Martian day 4,523 of the Mars Science Laboratory mission — at 13:23:32 UTC. NASA/JPL-Caltech Written by Lucy Lim, Planetary Scientist at NASA Goddard Space Flight Center
      Earth planning date: Monday, April 28, 2025
      Curiosity is back on the road! For sols 4525 and 4526, we have an isolated nominal plan in which the communication pass timing works out in such a way that the rover can fit in fully targeted science blocks on both sols rather than just the first sol. So in this power-hungry Martian winter season, we’re in a good position to take advantage of the power saved up during the missed uplink.
      The weekend drive went well and delivered the rover into a stable, arm-work-compatible position in a workspace with rock targets that we could brush with the DRT. Happy days! The DRT/APXS/MAHLI measurements will bring us geochemical and rock texture data from local bedrock blocks “Bradshaw Trail” and “Sweetwater River.” Further geochemical information will come from the ChemCam LIBS rasters on a more coarsely layered target, “Breeze Hill,” and an exposed layer expressing both polygonal features and a vein or coating of dark-toned material, “Laguna Mountain.”  
      Long-distance imaging with the ChemCam RMI included a mosaic to add to our coverage of the boxwork sedimentary features of the type Curiosity will soon be exploring in situ. A second RMI mosaic was planned to cover a truncated sedimentary horizon on the Texoli butte that may provide further evidence of ancient aeolian scouring events.  Meanwhile, the “Morrell Potrero” Mastcam mosaic will provide some detail on the base of the boxwork-bearing “Ghost Mountain” butte and on a ridge nearby. In the drive direction, the “Garnet Peak” mosaic will capture some potentially new rock textures and colors in the upcoming strata.
      Nearer-field imaging in the plan includes Mastcam documentation of some troughs that provide evidence for sand and dust movement in response to the modern aeolian environment. Additionally Mastcam mosaics went to “Breeze Hill” (covering the LIBS target) and “Live Oak” to document variations in bedding, color, and texture in the nearby bedrock. 
      A few observations of the modern environment were scheduled for the afternoon: a phase function sky survey to look for scattered light from thin water-ice clouds and a separate set of cloud altitude observations.
      Finally, a Mastcam documentation image was planned for the AEGIS LIBS target from the weekend plan! This reflects an update to the rover’s capability in which the AEGIS target can be determined and downlinked in time for the decisional downlink pass, so that we know where to look for it during the next planning cycle.

      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.

      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.
