Explanation:
There is gravity in space – lots of it. Gravity is everywhere. It is true that as you get farther from the earth, its gravitational pull weakens. But it dies off quite slowly (compared to nuclear forces). And gravity never goes completely away. When you get very close to some other large body; the moon, Mars, or the sun; its gravity dominates over that of the earth. Only then can you neglect earth's gravity. Because gravity is everywhere in space, objects in space are always falling: towards the earth, towards the sun, and towards the galactic center. There are two reasons that objects seem to be floating without gravity in space when they are really falling.
Tethers are like ropes. One end is hooked to the spacewalker. The other end is connected to the vehicle. The safety tethers keep astronauts from floating away into space.
