In 2012 NASA landed a rover called curiosity on Mars. NASA thinks that in about 35-40 people might be able to live on Mars.
They are planning for more rovers to go up and explore The red planet. Curiosity is equipped with a drill for taking samples and a laser.
How long will curiosity last?
How hard will it be for humans to live on Mars?
I now understand that the mars rovers are really important for finding if Mars is suitable for humans.
