Key events and trends
● ESA Approves New Earth Observation Missions: The European Space Agency has greenlit two new missions, Hibidis and SOVA-S, aimed at studying Earth's ecosystems and atmospheric gravity waves, respectively. Hibidis will monitor forest undergrowth using a unique spectrometer, while SOVA-S will track atmospheric waves that affect weather predictions. Both missions are budgeted at €35 million and are set for launch within three years.
↳ Community pulse (chats): highlighted that these missions underscore the potential for impactful science without enormous budgets. Participants expressed enthusiasm about the innovative approaches to Earth observation.
● NASA's Findings on Ceres: A reanalysis of data from the Dawn mission revealed that Ceres has a complex surface with steep slopes and bright spots indicating subsurface brine reservoirs. The findings suggest that Ceres could have once harbored a subsurface ocean, raising questions about the potential for microbial life.
↳ Community pulse (chats): discussed the implications of these findings for future missions, emphasizing the need for careful planning in sample collection due to the planet's surface conditions.
● NASA's MAVEN Mission Declared Lost: NASA officially announced the loss of contact with the MAVEN spacecraft on December 6, 2025, which was studying Mars' atmosphere. ↳ Community pulse (chats): noted the significance of this loss for ongoing Martian research and expressed hope for future missions.
● Super Heavy B20 Testing: The new Super Heavy B20 booster has begun its hydrostatic testing at the Massey site, with expectations for a flight test in the summer.
↳ Community pulse (chats): provided updates on the assembly of the next Super Heavy booster, indicating high hopes for the upcoming flight tests.
