    Any sort of long continuous thruster can do that in deep space, assuming there’s enough fuel / fuel to weight ratio. And ion engines are simply extremely fuel efficient, but also extremely weak in their actual output.

        Nah, it’s for masses out in microgravity, not a lift off / landing type thing.

    It seems weird to me that they would measure a thruster in maximum speed and not by the force is generates. Doesn’t the maximum speed depend on the mass it is propelling and a bunch of other factors like friction and gravity?

      No, that is the time to maximum speed. Maximum speed depends solely on exhaust speed (how fast the particles get accelerated).

      And no friction in space. Well, almost none.

      What’s weird is that they say km/h. Space and rocket stuff is usually in m/s.

        The grandparent comment is correct. There is no such thing as engine-specific “maximum speed”. If you add more fuel, you can always go faster (until the speed of light).
