Gateway's status is unclear at the moment. Firefly's Alpha rocket is back. After a launch failure last April, they reached orbit with a test flight - the third full success in 7 flights (2 failed to reach orbit, 2 reached a lower orbit). Russia fixed its damaged launch pad, the next mission...

Are you sure you have suitable velocities for these particles? If they are way too fast, they'll spread out like a sphere.

Every major browser has some spellchecking that can be enabled. Usually you can add new words to the dictionary, too (try right-click -> "add to dictionary" or similar). That's great for some technical words and other things that you might use repeatedly and don't want to see highlighted.

Isaacman has been busy. Besides the updates above, here is a 1 hour press conference on the future of Artemis News coverage For Artemis II, they'll have to inspect helium tanks, replace batteries of the flight termination system (FTS), and work more on leaks. To be determined how long that...

Seeing something is easier if the surface has sunlight. You can do infrared measurements either way, but there is no visible light without sunlight. Rollback of Artemis II is underway Mike Fincke has revealed that it was him with the "medical event" without saying what it was. Edit: Expected...

Doesn't look so good for Artemis. This is something they discovered after the WDR. If they roll it back, we are looking at the April launch windows the earliest.

The Artemis WDR was successful, it reached the planned T-29s. There were some holds to address issues in between but all of them has been resolved fast enough - if this had been a launch attempt, it could have proceeded to launch. Edit: NASA now aims at a launch on March 6 (March 7 by UTC)...

Yes, they want the far side to be in sunlight when they fly over it. Fueling for WDR 2 is ongoing

Second WDR for Artemis will start in ~12 hours - with fueling in two days. NASA looked into options to launch a few days earlier, but the timeline is now leading to a launch no earlier than March 6 again (the start of the initial launch windows).

Vulcan Centaur launched another military satellite. There were a lot of sparks 65 seconds after launch. From a different perspective, it looks like there are already flames at the wrong spot 20 seconds after launch. ULA calls it "an observation". If that reminds you of something, it's probably...

China successfully performed an in-flight abort test of Mengzhou, its next crewed capsule that will support both missions to LEO and to the Moon. It was also a landing test for Long March 10: Soft splashdown next to the ship that is expected to catch it in the future.

Artemis II Wet Dress Rehearsal: Test Terminated at T-5:15 A hydrogen leak they couldn't fix. If they can retry the WDR soon then they might still make a February launch window, but if it delays things by more than 3 days then the launch will shift to March.

SLS is fully loaded, T-27 minutes. That's most of what we'll see externally, besides retracting the crew access arm at T-8 minutes. At NSF commentators discussed that a successful launch of Artemis 2 will likely delay Crew-12 until the astronauts return, apparently NASA cannot or does not want...

10 hours 30 min The poll to begin tanking will be in 10 min, if things go well then a small amount of propellant will be used to cool down everything starting in 20 minutes, and serious tanking will start in 1 hour 5 minutes. NASA NASA Spaceflight The Launch Pad This is only the WDR, but it...

The countdown to the wet dress rehearsal (WDR) has started, 45 hours to go. Here is the schedule. The core stage will be powered up in ~5.5 hours. Things will get much more eventful in the last 12 hours when tanking begins.
