Does anything really have weight in space?

You're right. ESA got it right; Fox screwed it up. Never let a reporter talk about science.

The WEIGHT of something depends on how close it is to something ELSE (like a planet or star). The MASS of something is a measure of how much material is in it, and doesn't change because of location.

Weight is like force:
F=ma - W=ma, where a is the acceleration due to gravity.

If I recall correctly though, mass will increase with speed. Relatively anyways.
