UC Berkeley’s Space Sciences Laboratory (@ucbssl.bsky.social) is one of only two university-based centers in the U.S. capable of managing the full life cycle of a satellite mission. Watch how SSL leads NASA missions like ESCAPADE — the first dual-satellite mission to another planet, headed to Mars.

“We’ve established that the observatory is fully functional,” said Julie McEnery, #NASARoman senior project scientist at NASA’s Goddard Space Flight Center. “The telescope can guide and take exposures, data flows appropriately, and we can slew from one place to another for observations.” 🔭

IT'S ALIVE! 🛰️⚒️ The initial critical operations phase (done just after launch) is complete for the Martian Moons eXploration mission, including steps like unfolding the solar panels, ensuring attitude control on 3-axis is good, and releasing the catch on medium-gain antenna so it can look around 👀.

Update: KOSMOS 2612 made a manoeuver back to the orbital altitude of ICEYE-X36 late on Oct 19. This slowed down the drift away from the latter. It appears it is not done with ICEYE-X36 yet.
