London, Feb 25 : Apollo astronaut Buzz Aldrin has said in a draft paper that NASA needs serious reform or significant organisational overhaul.

According to a report in New Scientist, the draft paper, posted to the National Space Society blog, outlines a plan to replace George W Bush’s 2004 Vision for Space Exploration, which called for returning astronauts to the Moon by 2020.

It outlines a plan that focuses on sending astronauts first to new targets, such as asteroids.
