Since there's no drag, you can accelerate as much as you want given the fuel in your pack. In fact, propellant is talked about in terms of Detla-V (delta in velocity).
It seems like the first models of cosmonaut suits gave about 70 m/s of DV while the most recent astronaut MMUs give about 25m/s [1]. So, I don't think an astronaut could de-orbit themselves with just their suit alone.

- kayodelycaon 5y agoThere is drag on the International Space Station.
- fennecfoxen 5y agoThere is, but the drag is so small that they operate an entire space station in that orbit. It'll be quite some time before it starts to make a difference.

- inglor_cz 5y agoThere is non-0 drag at this distance from Earth and it is the main reason for orbital decay. https://en.wikipedia.org/wiki/Orbital_decay https://en.wikipedia.org/wiki/Orbital_decay But from a POV of an astronaut fiddling around with his propulsion unit, this drag is low.
