    I was watching the operational mission docking to ISS and wondered, what power do modern spacecraft use?

    I remember Apollo 13 when "stir the tank" and the oxygen tank exploded. We're not going back.

    Tesla (car) Li ion batteries or something very similar are used I think. Photovoltaics on the trunk are lit only half the time while in orbit.

    ISS has oxygen tanks as any long duration mission needs. I guess they are not as near the edge of the engineering envelope as Apollo's were.

    BTW how is Musk doing with his covid?

    Apollo to the moon had a very tight weight budget. And lead-acid batteries :). Were lithiums available then, they might not have gone so bleeding edge tech with the cryo systems.
