In the Supergirl episode "Better Angels" we have the following exchange between Kara (Supergirl) and her sister:

Alex: Once you're in space, there's no atmosphere. There's no gravity. You wouldn't be able to generate thrust, you wouldn't be able to breathe, you wouldn't be able to get back.

Kara: There is no other way.


My question is, why was Supergirl unable to breathe in space?

why could Supergirl not be able to breathe in space?

Because no-one can...there's no air.

She can't breathe in space unless she stores solar energy and holds her breath.

In the modern version of Superman (in the comics at least until the next version), Superman's sight, stamina and breath powers have been substantially reduced, and the character was also shown as requiring an oxygen mask for prolonged travel in space or underwater.

The same would apply to Supergirl.

I suspect though you are asking why Supergirl became unconscious and had to be rescued.

Well, she'd just lifted the 1 million ton Fort Rozz into orbit and beyond...that would have expended a...ahem...superhuman amount of energy which would have depleted her reserves. Plus the air is essentially too thin to breathe over 10,000 meters and Earth orbit is substantially higher than that.

So, she ran out of energy and breath and fell unconscious.

    Prison Warden: There ain't no air in space! Homer: There's an air and space museum. – Valorum Aug 28 '16 at 19:23

    @Valorum That's where they keep the famous air and the historic space. – Paulie_D Aug 28 '16 at 19:27

    @Paulie_D - But the writers know much more than the characters do. Characters can say the wrong things, even if the writers know better. – John Sensebe Aug 28 '16 at 19:33

    I'm not sure where you got your info, but this assertion is laughable: the air is essentially too thin to breathe over 10,000 feet. Having vigorously exercised over 15,000 feet, I can assure you that you are incorrect. – Mat Cauthon Aug 28 '16 at 22:55

    Maybe they meant 10,000 metres. – Steve Bennett Aug 28 '16 at 23:25

Well since superman has done things like held a miniature blackhole in the palm of his hand or picked up all of earth's nuclear missiles and threw them in the sun or when he pulled whole planets around for supergirl to be so weak only thing I can think of is that she was on earth for a shorter amount of time with the added fact there's plenty of proof stating that female kryptonions are a bit weaker but still she should have been able to atleast fly back

    Those things happened in a different continuity. – Valorum Nov 4 '16 at 14:46
