Miles Commodore @miles_commodore - My dad sold the house I grew up in back in 1999. It's 60 years old, 2,500 SF, on a third of an acre on Long Island NY... Yup, 33K a year in property taxes!

Military History Now @MilHistNow - Video: You're looking at newsreel footage of U.S. Marines under heavy fire after landing on on Iwo Jima. It happened on this day in 1945.

Narendra Modi @narendramodi - Saddened by the passing of Lok Sabha MP from Shillong, Dr. Ricky AJ Syngkon. He will be remembered for his dedicated service to the people of Meghalaya. My thoughts are with his family, friends and supporters during this difficult time. May his soul rest in peace.

NASA Administrator Jared Isaacman @NASAAdmin - After overnight data showed an interruption in helium flow in the SLS interim cryogenic propulsion stage, teams are troubleshooting and preparing for a likely rollback of Artemis II to the VAB at @NASAKennedy. This will almost assuredly impact the March launch window. @NASAwill continue to provide updates as they become available.

NASA Administrator Jared Isaacman @NASAAdmin - As an update to my earlier post.
- The ICPS helium bottles are used to purge the engines, as well as for LH2 and LOX tank pressurization. The systems did work correctly during WDR1 and WDR2.
- Last evening, the team was unable to get helium flow through the vehicle. This occurred during a routine operation to repressurize the system.
- We observed a similar failure signature on Artemis I.
- The Artemis II vehicle is in a safe configuration, using ground ECS purge for the engines versus the onboard helium supply.
- Potential faults could include the final filter between the ground and flight vehicle, located on the umbilical, though this seems least likely based on the failure signature. It could also be a failed QD umbilical interface, where similar issues have been observed. It could also be a failed check valve onboard the vehicle, which would be consistent with Artemis I, though corrective actions were taken to minimize reoccurrence on Artemis II.
Regardless of the potential fault, accessing and remediating any of these issues can only be performed in the VAB.
As mentioned previously, we will begin preparations for rollback, and this will take the March launch window out of consideration.
I understand people are disappointed by this development. That disappointment is felt most by the team at NASA, who have been working tirelessly to prepare for this great endeavor. During the 1960s, when NASA achieved what most thought was impossible, and what has never been repeated since, there were many setbacks. One historic example is that Neil Armstrong spent less than 11 hours in space on Gemini 8 before his mission ended prematurely due to a technical issue. A little over three years later, he became the first man to walk on the Moon.
