The #ArtemisII mission has quite an impact on ... the operation of the James Webb Space Telescope as #JWST operations plan currently assumes roughly a quarter of the usual #DeepSpaceNetwork (DSN) access will be available, which has a direct impact on the number of science visits that can be executed and the volume of data that can be downlinked."

RE: #Artemis

And now on #ArtemisII Update to discuss "the next steps": https://www.nasa.gov/news-release/nasa-invites-media-to-discuss-next-steps-for-artemis-campaign/

In the 20-minutes interview #Artemis program was changed. And the Aerospace Safety Advisory Panel Annual Report https://www.nasa.gov/news-release/nasas-aerospace-safety-advisory-panel-releases-2025-annual-report/ also has something to say.

"The USA needs to take over the Moon and stop all this phases nonsense. We’ll have a full Moon every night, unless werewolves become a big problem. We might even bring the Moon closer so getting there isn’t such a hassle": Donald Trump as cited in #ArtemisII

And the #ArtemisII stack is back in the VAB, arriving around 1:00 UTC today: https://www.nasa.gov/blogs/missions/2026/02/25/nasa-artemis-ii-rocket-returns-for-repairs/ - while in the assembly building, technicians will troubleshoot the helium flow issue to the rocket’s upper stage, replace batteries on the rocket’s upper stage, core stage, and solid rocket boosters as well as service its flight termination system.

The #ArtemisII stack arrived back at the pad today, with a launch on April 1st (Europe: April 2nd) still a possibility: https://www.nasa.gov/blogs/missions/2026/03/20/nasas-artemis-ii-rocket-arrives-at-launch-pad-39b/ and https://www.esa.int/ESA_Multimedia/Images/2026/03/Artemis_II_rolls_again and many more roll-out pictures in https://www.flickr.com/photos/nasahqphoto/albums/72177720332614865/

Due to weather, NASA now is targeting early Wednesday, Feb. 25, to roll the SLS (Space Launch System) rocket and Orion spacecraft for #ArtemisII off the launch pad and back to the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida: https://www.nasa.gov/blogs/missions/2026/02/23/nasa-targets-artemis-ii-rollback-on-wednesday/ - cold temperatures and high winds are expected Tuesday, and rolling on Feb. 25, gives teams enough time to complete preparations at the launch pad that were limited today by high winds in the area.

NASA is taking steps to potentially roll back the #ArtemisII rocket and Orion spacecraft to the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida after overnight Feb. 21 observing interrupted flow of helium to the SLS (Space Launch System) rocket’s interim cryogenic propulsion stage: https://www.nasa.gov/blogs/missions/2026/02/21/nasa-troubleshooting-artemis-ii-rocket-upper-stage-issue-preparing-to-roll-back/ - the upper stage uses helium to maintain the proper environmental conditions for the stage’s engine and to pressurize liquid hydrogen and liquid oxygen propellant tanks; the systems worked during NASA’s Artemis II wet dress rehearsals, but teams were not able to properly flow helium during normal operations and reconfigurations following the wet dress rehearsal that concluded Feb. 19.

45 minutes til the simulated #ArtemisII launch, and according to https://www.youtube.com/watch?v=-KYhqePsm38 and https://www.nasa.gov/blogs/missions/2026/02/19/live-artemis-ii-wet-dress-rehearsal-coverage/ the 2ns wet dress rehearsal is going to plan. How the outcome will be reported: https://www.nasa.gov/news-release/nasa-to-provide-coverage-of-artemis-ii-wet-dress-rehearsal/

As NASA moves closer to launch of the #Artemis II test flight, the agency soon will roll its #SLS (Space Launch System) rocket and Orion spacecraft to the launch pad for the first time at the agency’s Kennedy Space Center in Florida to begin final integration, testing, and launch rehearsals: #VehicleAssemblyBuilding to Launch Pad 39B.

The #ArtemisII roll-out is scheduled to begin at 12:00 UTC today (Saturday) and will last 8 to 12 hours: https://www.youtube.com/watch?v=nrVnsO_rdew = webcast, https://www.nasa.gov/artemis-ii-press-kit/ = mission press kit, https://www.nasa.gov/blogs/missions/2026/01/16/artemis-ii-moon-rocket-ready-for-big-move/ = the finished stack, ready to roll.

A the press conference #ArtemisII launch after the WDR went so well - see also https://www.nasa.gov/blogs/missions/2026/02/19/nasa-begins-artemis-ii-launch-pad-ops-after-successful-fuel-test/ issued just after it had ended - but this will not be confirmed before the Flight Readiness Review late next week.

"After running through terminal count for the #ArtemisII wet dress rehearsal, the launch team paused the clock at T-33 seconds in the countdown," says https://www.nasa.gov/blogs/missions/2026/02/19/live-artemis-ii-wet-dress-rehearsal-coverage/: "Teams are now reconfiguring and replenishing the liquid hydrogen and liquid oxygen systems, in order to recycle back to the T-10 minute mark and perform another run of terminal count. [...] The entire recycle process lasts approximately 60 to 90 minutes."

While preparing #ArtemisII for flight, NASA engineers are reviewing data after a confidence test Feb. 12, in which operators partially filled the SLS (Space Launch System) core stage liquid hydrogen tank to assess newly replaced seals in an area used to fill the rocket with propellant: https://www.nasa.gov/blogs/missions/2026/02/13/following-confidence-test-nasa-continues-artemis-ii-data-review/ - during the test, "teams encountered an issue with ground support equipment that reduced the flow of liquid hydrogen into the rocket. [...] Engineers will examine findings before setting a timeline for the next test, a second wet dress rehearsal this month. March remains the earliest potential launch window for Artemis II."

A live view of the #ArtemisII stack on the pad: https://www.youtube.com/watch?v=xCrPD7tfcr0 - where the countdown for the Wet Dress Rehearsal has begun at 1:13 UTC; see https://www.nasa.gov/blogs/missions/2026/01/31/countdown-begins-for-artemis-ii-wet-dress-rehearsal/ for the timeline and https://skyweek.wordpress.com/2026/02/01/generalprobe-wet-dress-rehearsal-fur-artemis-ii/ for maaany Artemis-related links going back to 2023.

So the #ArtemisII FRR went "go" on all counts, they hope to roll out the stack to the pad again on 19 March and be ready to launch on 1 April at 22:24 UTC - the table of possible launch dates in April https://www.nasa.gov/wp-content/uploads/2026/01/artemis-ii-mission-availability.pdf just had another one added for 2 April.

One more #ArtemisII piece in https://www.cbsnews.com/news/4-artemis-ii-astronauts-getting-ready-for-flight-to-far-side-of-the-moon-60-minutes-transcript/ (13-minutes video and transcript) - it also highlights the renewed 'race' between SpaceX and Blue Origin for building the Artemis III lander. And falsely claims that they are the first to actually show the Blue Moon MK1: see https://www.instagram.com/p/DRVZLMkkVgO/ from last November ...

Finally an #ArtemisII update on https://www.nasa.gov/blogs/missions/2026/02/08/nasa-conducts-repairs-analysis-ahead-of-next-artemis-ii-fueling-test/ - "technicians have replaced two seals in an area where operators saw higher than allowable hydrogen gas concentrations during the test. Engineers are analyzing the removed seals and developing plans to address all issues ahead of the next rehearsal." No date for that new wet dress rehearsal has been set, and a launch date will be determined only after it is over.

The #Artemis stack on the pad in a good image from the ISS: https://x.com/Astro_ChrisW/status/2018365716181705015 - processed with IrfanView, using AutoAdjustColors and contrast adjustment. Meanwhile the Wet Dress Rehearsal is in trouble because of - you guessed it - a hydrogen leak. Since the updates on https://www.nasa.gov/blogs/missions/ have become super-sparse it's hard to tell how serious the problem is.

In 10 minutes the #ArtemisII Fueling Test News Conference will stream at https://www.youtube.com/live/ycqk3uN_N6g - as announced in https://www.nasa.gov/blogs/missions/2026/02/03/nasa-conducts-artemis-ii-fuel-test-eyes-march-for-launch-opportunity/ and https://x.com/NASAAdmin/status/2018578937115271660 the first launch attempt has already been moved to March.

RE: #ArtemisII WDR: https://www.nasa.gov/blogs/missions/2026/02/03/artemis-ii-wet-dress-rehearsal-test-terminated-at-t-515/ - a lot of unfinished business ...

With the delay of the #ArtemisII WDR to Feb. 2 finally confirmed - #Crew12 pre-launch presser day: #NASA yet, but https://www.youtube.com/watch?v=C5-5By97H_8 promises to carry the first presser at 16:00 UTC - beware: shocking preview image - while https://www.youtube.com/watch?v=MLxcA8Crpkg will carry the second one with the crew at 18:00 UTC).

From today's #LPSC #NASA briefing: #AI will play a role even in #Artemis ... The two cited abstracts on the #LunarFoundationModel are https://agu.confex.com/agu/agu25/meetingapp.cgi/Paper/1930954 and https://agu.confex.com/agu/agu25/meetingapp.cgi/Paper/1929889

From the #LPSC #NASA HQ Briefing: the four American robotic #Moon landings planned for this year - the Blue Origin HLS demonstrator for #Artemis should go first, as early as next month. (There is a little #VIPER looking at the latter because this homeless rover might fly on a second demonstrator - if they can figure out how to get it from the 8 meters high lander to the surface.)
