NISAR is one big step closer to beginning its mission to study Earth’s changing surfaces 🌏 Today, the satellite successfully unfurled its 39-foot-wide (12-meter-wide) antenna reflector. It’s the largest reflector NASA has ever deployed in space! go.nasa.gov/41Iu20T

📹: The view from a Kuiper satellite launched on last week’s KF-02 mission with SpaceX. This imagery was captured over a 24-minute period — enough time for the satellite to travel 5,500+ miles in orbit, from over Italy to the Indian Ocean east of Madagascar.

I dug this out of a storage box the other day. It’s been a long and winding road since I was here 11 years ago for the groundbreaking of what would become Starbase.

All told, the boost kit can add about 20 mph, or 9 meters per second, to the space station's already-dizzying speed. arstechnica.com/space/2025/08/…

SpaceX does a great job at finding rideshares for missions like today's launch of Luxembourg's NAOS milsat. Still, it's been impossible for anything but Starlinks to fill up the payload capacity of a Falcon 9.
