Focused on @NASA& #39;s Lunar Surface Science Virtual Workshop #LunarSurface. Lindsay Aitchison on early #Artemis #lunar #EVAs: 6.5 day surface stays, 4 EVAs ~6 hrs each = 14-16 km terrain traversed (pre-rover ops). Could you #Moonwalk 2.5 miles per day in a #spacesuit? #SpacesuitUp!

I& #39;m assuming for that mileage that the astronauts stay together in a buddy system and cover the same terrain. For close ProxOps to the lander, they could spread out slightly.

Clarification! EACH EVA could have 16 km PER EVA between the 2 crewmembers! That& #39;s a lot! That is also the maximum, but it would likely be less since the crew would need to be somewhat static at sample collection sites and equipment deployment sites. It& #39;s task dependent.

Lindsay followed up and said that the maximum [round trip] distance was bounded by the scenario of the crew placing something as far away as possible [from the lander]. #EVA #operations #ToTheMoon!

More on this thread here with another Ryan @Ryan_N_Watkins, because "Ryan& #39;s" think about #Moonwalking!

When">https://twitter.com/Ryan_N_Wa... you can see "yourself" in the boots of the astronauts, you can think creatively on how they will operate and what they need, which reduces risks.
