If objects are weightless in space why can't an astronaut push the space shuttle by the power of his own muscles?

weightless is just a figure of speech. things in space are just lighter than they are on earth. the space shuttle weighs 220,000pds so in space it might weigh 100,000pds.

Does the speed of a satellite in orbit depend on its mass?
No. The speed of any orbiting body depends only on the energy of its orbit, meaning mainly its distancefrom the central body.When a Space Shuttle astronaut performs a 'space walk', and momentarily unhooks his feet from thehull of the shuttle, he and the shuttle are both in earth orbit. The astronaut and the shuttle have thesame orbital speed, and they stay close together, even though the shuttle has somewhat more massthan the astronaut has.

Why an astronaut in a space shuttle feels weightless?
"Weight" happens when the attraction of gravity on a mass is resisted, we only FEEL the weight when we are resisting gravity. Weightlessness therefore happens when gravity is not resisted - when you are in "free-fall".In a space when you are in orbit round the Earth, you are effectively in "free-fall" and therefore as you are not resisting gravity you are weightless (but not massless).
