This is a new ship — one that has never carried a crewed mission to deep space / the Moon, before. So it is expected that a chunk of the mission will include fiddling with the nobs and twiddly bits — to get all the creature comfort kinks worked out.
But live on YouTube streaming yesterday, the crew pointed out that they were working with Houston to slow the speed of fan/blower cycling… and boost the [presumably electric] heater coils’ output — to take into account that the skin of Orion gets chilled to below minus 220 degrees Fahrenheit. [Think of this like a jet’s cold air flow, flying trans-Atlantic — but vastly amplified; not negative 50 — negative 220.] That would certainly make for a chilly night, in space.
In the mean time, everyone is definitely wearing their… woolies.
Even so, Astronaut Victor Glover went so far as to suggest, for the next crewed mission, that the sleeping bags be more like “Himalayan grade” down-fill, rather than the lighter poly-filled ones presently onboard.
This is what shake-out missions are for, indeed. Godspeed, Artemis!
