Can satellites be serviced?

Hopefully that doesn't equate to alsheimers or something equally as mentally debilitating.

Doesn’t spelling go first?

JK, JK!

It's not the gravity, but rather the drag from the extremely rarified air up there.

At 550kM, I'd imagine it is next to negligible. The density is on the order of two ten-trillionths that of sea level (21.4 nanograms/cubic meter?).

"Is There Gravity in Space?
Gravity causes every object to pull every other object toward it. Some people think that there is no gravity in space. In fact, a small amount of gravity can be found everywhere in space. Gravity is what holds the moon in orbit around Earth. Gravity causes Earth to orbit the sun."

What Is Microgravity? (Grades 5-8) - NASA

Microgravity is the condition in which people or objects appear to be weightless. The effects of microgravity can be seen when astronauts and objects float in space.

That probably should have been a reply to TheKrel's post rather than mine about atmospheric density.

Of course gravity is what keeps things orbiting rather than wandering off into space in a linear path so that's a good thing.
