minus-squareblack_flag@lemmy.dbzer0.comlinkfedilinkEnglisharrow-up12·4 days agoI mean I know it’s a joke but you can’t actually break orbit just by throwing something from the moon, right?
minus-squaresmeg@feddit.uklinkfedilinkEnglisharrow-up22·4 days agoThe 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
minus-squaremkwt@lemmy.worldlinkfedilinkEnglisharrow-up5·3 days agoEven 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.
minus-squareCheeseNoodle@lemmy.worldlinkfedilinkEnglisharrow-up2·3 days agoYou could probably gradually get it moving across the surface fast enough to escape though.
minus-squareicelimit@lemmy.mllinkfedilinkEnglisharrow-up1·4 days agoMan even a 5.6 is only 0.9km/s. I thought we could give the moon a ring of bullets.
minus-squareTomassci@sh.itjust.workslinkfedilinkEnglisharrow-up8·3 days agoNot the moon, but this comic would work on some asteroids.
minus-squareblack_flag@lemmy.dbzer0.comlinkfedilinkEnglisharrow-up3·3 days agoHow small would it have to be?
minus-squarejballs@sh.itjust.workslinkfedilinkEnglisharrow-up5·3 days agoThis 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.
minus-squaremarcos@lemmy.worldlinkfedilinkEnglisharrow-up5·3 days agoNor can you throw a spaceship around on the Moon. So maybe that cartoon isn’t about the Moon.

I wish I could escape myself…
