But if I were outside and traveling on the roof of that train, or if I had chosen to travel on the exterior wing of that plane, and then I chose to step off, I would no longer be traveling at that vehicle's speed, would i? So how can the astronauts step off the space station's exterior apparatus and not go flying out into space?Because they are moving at the same relative speed. Think of it like being able to walk about an airplane in flight or a train moving down the tracks.

You mean no atmosphere (not wind).Adding to what COLGeek stated, there is no wind up there to push away an astronaut if they step outside the door.
Perhaps more confusing and answer would be to us General Relativity and note that it is proper to consider that the Earth is rotating under them at 17,500 mph and they are still.
Thanks for the wiki dump. Please explain.The International Space Station (ISS) is a modular space station (habitable artificial satellite) in low Earth orbit. It is a multinational collaborative project between five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada).The ownership and use of the space station is established by intergovernmental treaties and agreements astro merch. The ISS program here evolved from the Space Station Freedom, an American proposal in the 1980s to construct a permanently crewed Earth-orbiting station.
The ISS serves as a microgravity and space environment research laboratory in which scientific experiments are conducted in astrobiology, astronomy, meteorology, physics, and other fields. The station is suited for testing the spacecraft systems and equipment required for possible future long-duration missions to the Moon and Mars. It is the largest artificial object in space and the largest satellite in low Earth orbit, regularly visible to the naked eye from Earth's surface. It maintains an orbit with an average altitude of 400 kilometres (250 mi) by means of reboost manoeuvres using the engines of the Zvezda Service Module or visiting spacecraft. The ISS circles the Earth in roughly 93 minutes, completing 15.5 orbits per day.
