Welcome to c/science_memes @ Mander.xyz!
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

Escape velocity means you could stay in orbit. It doesn't guarantee anything if you launch at the wrong angle.
Exactly. It's the minimum speed required to get into orbit assuming you get the direction correct. If you launch vertically, you'll almost certainly come back down, no matter how far out into space you go. The only consideration is that if you go far enough out you might be influenced by the gravity of something else like the moon which could change your trajectory.
That is not the definition of escape velocity. Escape velocity is the minimum velocity to escape a body's gravity well entirely. Orbital is much lower
