Nasa needs to go back to the moon BEFORE a Mars mission: Buzz Aldrin urges space bosses to delay deep space plans - but believes man could blast off to the red planet in 2040

While Nasa says the first manned trip to Mars could take place as early as 2035, the second man to walk on the moon has urged them to wait. 

Buzz Aldrin told Dailymail.com he believes that mankind should head for the red planet in 2040, but not until we explore and build habitats on the moon with the other space agencies of the world first.

Aldrin said this mission should be an international collaboration and the input of big businesses, then a human colony could be established on Mars.
