Nasa looks to Mars, not moon
A NASA strategy proposal shifts the US human space program away from returning to the moon in favour of a stepping-stone approach aimed at reaching Mars, including using commercial space launch services, according to a document seen by Reuters.
The proposal is not yet official policy but is the US space agency's response to one of five options contained in review ordered by President Barack Obama of Nasa's post-shuttle program that plans to put humans on the moon again by 2020.
A summary of the Human Space Flight Review Committee report, released by the White House on Tuesday, warned however that there could be no meaningful future human space exploration program without more money.
