The head of NASA has just admitted something that is likely to greatly disappoint anyone hoping that we’ll start a colony on Mars in the next few decades. NASA’s chief of human spacefligth William H. Gerstenmaier acknowledged that the agency couldn’t put a date on missions to the Red Planet because they don’t even have the funding to make it happen.

Gerstenmaier’s stunning admission comes just a few days after Vice President Mike Pence hailed the new Trump Administration budget as a sign that they were ushering in a “new era” of ledearship in space, including a return to the moon and a manned mission to Mars.

“I can’t put a date on humans on Mars, and the reason really is that at the budget levels we described, this roughly 2 percent increase, we don’t have the surface systems available for Mars,” said NASA’s William H. Gerstenmaier according to the Daily Mail. “The entry, descent and landing is a huge challenge for us for Mars. We think an unfuelled mars asset vehicle would weigh around 20 tons, that’s a 20 fold increase on a rover.”
