so we can know more about it
Astronauts have not landed on Uranus and Neptune, as they have only visited the Moon, Mars, and the satellites of Jupiter and Saturn. Exploration of these distant gas giants would require advanced technology and significant challenges to overcome.
none
As of now, no astronauts have stepped on Mars. All manned missions so far have been to the Moon. Plans for manned missions to Mars are currently in development by various space agencies, with the goal of landing astronauts on the planet in the future.
A spacecraft traveling to Mars would take about 6-9 months using current technology to complete the journey. The speed would depend on the trajectory chosen, but typically it would travel at an average speed of about 24,600 mph (39,600 km/h) during the trip. This speed is manageable and does not pose a risk to the astronauts on board.
ALOT
We've never made it there, but no.

There are no people on Mars, and no astronauts have visited Mars. The Moon, yes, Mars, no.
No not yet
No astronauts have ever been to Mars, and no rock samples have ever been sent to Earth.
You appear to be misinformed. It is more difficult to send people to mars because it is so much farther away. That is why we have not sent astronauts to mars yet, but we have sent astronauts to the moon.
