    1. I struggle to believe Blue Origin were ever a serious contender for a part in the Artemis program. They just don’t have the experience or track record that SpaceX have. Their only role is as an alternative bidder to keep SpaceX from charging exorbitant amounts.

    2. ‘Threatens’ doing a lot of work there. They have two companies making landers and both can’t reliably get into orbit, and both are way behind schedule.

      Honestly, better explosions during testing than explosions mid moonflight. And the space program has a loooong history of explosive disassemblances during tests anyway.

    4. Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I’ve seen in this thread:

      HLS likely won’t be the main delaying factor for a lunar landing. The suits are not going to be ready until 2031. Boeing can’t weld anymore so increasing delivery frequency of SLS isn’t going to happen.

      This also assumes that ESA don’t stop supplying ESMs now NASA are not honoring their part of the bilateral agreement. If ESA do then there isn’t any backup, there isn’t any alternative in development.

      This is also your daily reminder that we could have had a station in lunar orbit by 2028 and be doing awesome science if it had not been cancelled. We could have been launching dozens of microprobes to greatly improve our planetary science programs. We would have had regular access to the moon as soon as HLS and a suit are ready without needing SLS & Orion to take them there.

      Isaacman’s timeline was a fantasy from the get-go. This is a wake up call, but the administration won’t listen.

      I don’t have any love for either of these bozos but if I have to pick space penises, I’m choosing SpaceX.

    8. Man, another setback for Artemis II timing. Seems like every step forward comes with a hardware test that goes sideways. Hope they can isolate the issue quickly without too much schedule ripple.

      Ummm…does more than threaten…zero chance there are three missions to the moon next year (not that there was a chance of this anyway).

    10. There’s no “threat.” It absolutely will delay NASA’s moon program.

      Bezos and Trump will find a way to push the cost of this explosion onto taxpayers. The delays will be “unforeseen costs”
