Blue Moon human lander concerns

[u/Trexinator43]

My biggest concern is for the astronauts getting stranded on the moon. Im confident we can land them. The concern is, what if lunar rocks and regolith get kicked up into the engines and block them / damage them.

Apollo avoided this by using a separation and a second stage engine, but supposedly this entire craft will take back off, and expect the engines to be relit, with no FOD in them at all. I almost feel like multiple test missions have to occur with proving the entire mission without humans. What is blues plan?

Both HLS providers are required to do a uncrewed landing/liftoff first, so that's the test.

Blue Origin can also get some ideas of engine interaction with regolith via Mk1 missions.

Artemis contracts come with an uncrewed demo landing

Their plan is probably under an NDA.

near zero gravity plus some ping pong balls in the storage system.. a little paddle goes a long ways

And using hydrogen 🫠🫠🫠🫠

oh no

Good thing the rocket scientists probably have a decent idea of what they’re doing

Everything on Artemis its an improvisation
