NASA has officially decided that the EM-1 mission (first SLS launch, second Orion capsule launch, scheduled for a leisurely three weeks in space, including several days around the Moon) will not be manned.
It wasn't supposed to be manned, it was designed for unmanned (to test the system for a lengthy flight) but Trump decided, randomly, it should be manned and made NASA work out whether that could happen. It's scheduled for 2019, which makes his most recent statement ("Can we get to Mars before 2020? 2024 at the latest?") even more retarded.
I'm glad to see NASA isn't insane enough to send a crew on a three-week Moon flight without, you know, testing the fucking thing first.
