Space is a open area. It is completely quiet in space. Mercury is the closets to the sun. The moon was once a part of the planet Earth. A full NASA suit cost 12,000,000. 70% of that cost is for the backpack and control module. The footprints on the moon will be there for 100 million years. The moon has no atmosphere which means there is no wind to erode the surface and no water to wash the footprints away. Venus has a slow axis rotation which takes 243 Earth days to complete its day. The orbit of Venus around the Sun is 225 Earth days, making a year on Venus 18 days less than a day on Venus.
