Sentinel-6B ocean monitoring satellite launches aboard Falcon 9
Sentinel-6B, a joint US-European ocean monitoring satellite, launched Sunday aboard a SpaceX Falcon 9 rocket. Liftoff from Vandenberg Space Force Base took place at 9:21 p.m. Pacific time (05:21 UTC on Monday). The Sentinel-6B spacecraft is the second of two Jason Continuity of Service (Jason-CS) missions, launching five years after its sister satellite, Sentinel-6A Michael…

Scientists use Cassini data to discover new molecules in Enceladus water jets
Located around Saturn is the icy moon Enceladus — one of the most interesting and potentially habitable moons in the solar system. NASA’s Cassini mission extensively studied Saturn and its moons from 2004 to 2017 and, in 2005, revealed large geyser-like jets extending from Enceladus’ south pole. Later studies would suggest that a massive subsurface…

Juno measures oxygen production on Europa
Using NASA’s Juno spacecraft, scientists have calculated the rate of oxygen production on Jupiter’s moon Europa — the first time any spacecraft had directly measured charged oxygen and hydrogen particles from the moon’s atmosphere. From these measurements, the team determined the rate of oxygen production to be much lower than estimated in previous studies. Europa,…

Juno discovers salts and organic compounds on Ganymede’s surface
After a flyby of Jupiter’s largest moon, Ganymede, in 2021, Juno and a team of scientists have discovered the presence of mineral salts and organic compounds on the surface of the icy moon. The new findings will allow scientists to better understand where Ganymede came from and the composition of its deep subsurface ocean. For…
