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 due to the risk of imploding, 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.
