@cosmos4u@scicomm.xyzEarth vanishing behind the Moon for the #ArtemisII Orion - only a super-crappy camera caught the scene live. Closest approach to the Moon and largest distance from Earth also just happened. The latter should reappear at about 23:22 UTC and communication regained: https://skyweek.wordpress.com/2026/04/07/die-orion-von-artemis-ii-ist-jetzt-hinter-dem-mond/ is covering events now ... and hopefully many *good* photographs arriving in the coming days.

@cdarwin@c.imAs the Artemis II mission heads for a flyby of the moon,
the Orion crew module is testing one of NASA’s most ambitious upgrades to space communications yet:
a laser-based system called O2O.
Short for Orion Artemis II Optical Communications System,
O2O caps more than two decades of work by NASA and the Massachusetts Institute of Technology Lincoln Laboratory
to build better high-bandwidth links for deep space.
The system is designed to send data down to …

Die Crew der "Artemis 2"-Mondmission hat sich weiter von der Erde entfernt als jemals Menschen zuvor. Die vier Astronauten knackten mit ihrer "Orion"-Kapsel den 1970 aufgestellten Rekord der "Apollo 13"-Mission, wie die US-Raumfahrtbehörde NASA mitteilte.

@me@mastodon.peterjanes.ca @cosmos4u@scicomm.xyzNASA has finally published a detailled simulation of what the #ArtemisII lunar flyby will look like from the Orion: https://www.youtube.com/watch?v=dmQ4546iIvI - happy to see that it matches the two simulations (prepared on my request, assuming an April 1st launch) I had shown on March 30th in https://skyweek.wordpress.com/2026/03/26/allgemeines-live-blog-ab-dem-26-marz-2026/#Mar30 had essentially nailed it. Actual times of key events have recently been added to https://www.nasa.gov/missions/artemis/artemis-2/nasa-sets-coverage-for-artemis-ii-moon-mission/ (under Monday, April 6) - the main question now is how much of this culmination of the mission we will see ... and when. At a press conference Sunday at 22:30 UTC more information is expected.

NASA’s Artemis II crew members are boarding the agency’s Orion spacecraft to begin communication checks to confirm voice links with mission control and onboard systems.
Before entering the spacecraft that will be their home on the approximately
10-day journey around the Moon and back,
all four crewmates signed the inside of the White Room, an area at the end of the crew access arm that provides access to the spacecraft.

@cosmos4u@scicomm.xyzThe best view from the #ArtemisII mission so far came at noon UTC today when a solar-wing-mounted camera broastcast this view of Earth some 70,000 km away next to the ESM engines for a while. The Orion and the ESM are on their way back to perigee now - and around 23:45 UTC the trans-lunar injection burn is expected.

@cdarwin@c.imEven as Integrity, the mission moniker for the Orion capsule of Artemis II, ascended into the heavens days ago,
Donald Trump was announcing his intention to slash Nasa’s budget by 23%,
including a 46% cut for space science initiatives.
And the Artemis program that has run years behind schedule and billions of dollars over budget offers no guarantees that the next, far harder stages will run as smoothly.

@cosmos4u@scicomm.xyzSo far NASA hasn't released any post-flight images of the #ArtemisII heat shield (except for a weird under-water view) - but here is one, kind of, I have extracted from the series https://www.facebook.com/NavalBaseSD/posts/pfbid05mJ788QWZoVSugx81FqT9aqGMSmvdCNP9P7KQfXtc6GevGQMtCkh184xgFV3N26vl of images taken by the Naval Base San Diego during a series of precision crane lifts and movements to prepare the Orion spacecraft for its final cross-country trip to Kennedy Space Center.
@cosmos4u@scicomm.xyzDue 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.
@cosmos4u@scicomm.xyzDuring NASA’s #ArtemisII mission to the Moon, four astronauts will live and work inside the Orion spacecraft after launching atop the SLS (Space Launch System) rocket: https://www.youtube.com/watch?v=1lxDQj7CFyI - the crew will test Orion’s systems throughout their 10-day mission to ensure the spacecraft can keep astronauts safe and healthy in deep space.
@cosmos4u@scicomm.xyzNASA 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.
