Highly ionized neon gas detected at the center of the spiral galaxy Messier 83 by the Mid-Infrared Instrument (MIRI) aboard the NASA/ESA/CSA James Webb Space Telescope could be a telltale signature of an active galactic nucleus, according to a team of astronomers led by Space Telescope Science Institute scientists. This…

Only a few past missions, like NASA's GRAIL, have attempted operations in very low orbits around the moon. Credit: NASA WASHINGTON — DARPA is seeking proposals for a small lunar orbiter that could be used to test operations in very low orbits while prospecting for water ice. DARPA issued a…

Imagine you’re on the moon, digging up lunar regolith. You’re focused on the task at hand when you suddenly slip and fall, right into your pickaxe. Even in the moon’s weaker gravitational field, accidents are a real possibility. A sharp pain flares up on your right side, and you call…

The Russia-Ukraine war is arguably the first commercial space war on account of its use of private companies’ imagery for tracking and targeting. The conflict has demonstrated the advantage of knowing what’s happening on the ground and highlighted the role of the space domain for the critical Indo-Pacific region and…
