Weight in orbit would be equal--Zero. The difference would be mass...

'MESSENGER' is the Mercury Mission - See the related link listed below for more information:
Scientists have to study the moon rocks, as more were brought and a detailed study had to be done, this takes years and it was done in various countries.
It's called a space walk when a astronaut is "walking" outside her spacecraft in outer space. see wikipedia for more info: http://en.wikipedia.org/wiki/Space_walk
Since the anvil is more than twice as massive as the astronaut, the astronaut will move much more rapidly than the anvil, as they both move in opposite directions following the astronauts push. And chances are, the massive anvil with then collide with the astronaut's spacecraft, doing horrendous damage, and the foolish astronaut will then be unable to safely return to Earth. So when you are in outer space, be careful with your anvil. I wouldn't go throwing it around at random.
One More Astronaut was created in 1996.
SOHO (Solar and Heliospheric Observatory) not to be confused with the once "red light" district of London UK. See related link for more information
The three main stages in exploring a planet are: 1. send out a spacecraft that passes one or more bodies in space without orbiting them. 2. study a planet over a long period of time. and finally, 3. land instruments on a planet or to send instruments through its atmosphere.
The astronaut's inertia is MORE on the moon.
The moon is not a star. The moon is a solid, cold object orbiting a planet, and if it were orbiting alone it is large enough to be considered a planet by itself. A star is a massive ball of gas heated by internal fusion reactions, and weighs millions of times more than the moon.
Mass. Weight is different depending on gravity, but mass is always the same. On the Moon an astronaut weighs less, but has the same mass that they have on Earth.
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.
