The First Space Launch System Flight will Probably be Delayed
NASA is in the middle of developing a new heavy-lift rocket, that will be used to get humans beyond low Earth orbit to places like the Moon and Mars. The last time NASA was in full scale development mode was in the late 1970s and early 1980s for the beginning of the Shuttle program. According to some investigations on the part of the Planetary Society, it looks like NASA's going to miss their launch date of Nov 2018.
