Is this Nasa's most daring mission yet? Astronauts to land on asteroid three million miles from Earth - and stay for a MONTH | Mail Online: "The space agency Nasa is training a team of astronauts to land on asteroids after a three million mile journey - dwarfing the mere 239,000 miles travelled to the moon.

The mission, planned for the next decade, would land on an asteroid travelling at more than 50,000 miles an hour.

The astronauts will drive vehicles on the surface - and pick up skills necessary to destroy 'planet killer' asteroids that may approach our planet in future. "
