No, because Saitama can pretty much hold his breath in space for indefinite periods of time. Holding your breath in space without a spacesuit is extremely dangerous, but Saitama did it with no effort.

And no, Saitama can jump in the vacuum of outer space without the aid of a medium or surface to jump from. Confirmed in the intro.

Also, he didn't even realize he was in a vacuum until he found out about low gravity on the moon.
