The only place astronauts have been other than Earth, is on the moon. When they were there, they did some exploring to see what it was like. They took samples of the soil and rocks to bring back to Earth. They tried to learn as much as they could while they were there. If astronauts get to visit other planets, they would do the same kinds of things.
In 3955 the astronauts returned to Earth to find hte apes in control in Planet of the Apes.

The planet is very hot on the side facing the sun, up to 800°F (425°C), but in the near vacuum there, it could be dealt with by shielding and cooling. With Mercury's "day" being 58.6 of our days, astronauts could spend weeks on the "cold" side facing away from the Sun, or on the more-temperate boundary zones.
Astronaut did not land in Venus because the planet is hot. If the astronaut land on Venus, they will burn their selfs.
