Mars, Mission To Mars | featured news

Science editor Alan Boyle's Weblog: The end of a 520-day simulated space mission marks one more step in a succession of make-believe trips to Mars, leading up to the real thing.

NASA's next-generation rover mission to the surface of Mars needs more money – again. Nine months before the scheduled launch, the space agency says the mission has burned through its reserves and needs another $82 million to complete testing before liftoff.

Invoking the spirit of "Star Trek" in a scholarly article entitled "To Boldly Go," two scientists contend human travel to Mars could happen much more quickly and cheaply if the missions are made one-way. They argue that it would be little different from early settlers to North America, who left Europe with little expectation of return.
