bye bye 🙁Mars has the largest canyon in the solar system. It would reach from Los Angeles to Chicago if it was on Earth!
Mars has a very thin atmosphere, mostly carbon dioxide, but dust storms can cover the whole planet for months at a time. About every two years the Earth and Mars come close together. The planet has two moons, Diemos and Phobos.
Ideas for a manned mission to MarsIt would take about 6 months for a spacecraft to get to Mars but the crew would have to wait a year and a half before returning.
