Just remember to aim your jump exactly....... Or die floating in the void.

No pressure… because there’s no atmosphere.

I mean I know it's a joke but you can't actually break orbit just by throwing something from the moon, right?

[–] smeg@feddit.uk 37 points 3 weeks ago (2 children)

The escape velocity of the moon is 2.38km/s (compared to 11.2km/s on Earth) so you'd have to be throwing it pretty hard

Even if you went to some asteroids that have low escape velocities, a spacecraft still has all of the mass of a spacecraft--probably a few 1000 kg. So you probably can't get it going fast enough, even if you can escape yourself by jumping.

I wish I could escape myself..

[–] ButteryMonkey@piefed.social 5 points 3 weeks ago

Have you tried jumping? Sounds like that may be the ticket!

[–] CheeseNoodle@lemmy.world 3 points 3 weeks ago

You could probably gradually get it moving across the surface fast enough to escape though.

Man even a 5.6 is only 0.9km/s. I thought we could give the moon a ring of bullets.

Not the moon, but this comic would work on some asteroids.

[–] black_flag@lemmy.dbzer0.com 3 points 3 weeks ago

How small would it have to be?

[–] jballs@sh.itjust.works 8 points 3 weeks ago

This comment makes me want to play some Kerbal Space Program again, where you can launch yourself into orbit from Minmus (the 2nd moon) with a jump.

[–] marcos@lemmy.world 8 points 3 weeks ago

Nor can you throw a spaceship around on the Moon.

So maybe that cartoon isn't about the Moon.

If your fastball is 5324 mph, give the MLB a call!

[–] grysbok@lemmy.sdf.org 6 points 3 weeks ago

When it eventually lands, they're in for a hike.

[–] ns1@feddit.uk 4 points 3 weeks ago

Who else has done exactly this before on Gilly in Kerbal Space Program?
