Message to Edit: HTML is ON UBB Code is ON Smilies Legend	Originally posted by SpaceAholic on 04-16-2018 10:51 AM NASA will likely launch its first astronauts into deep space since the Apollo program on a less powerful version of its Space Launch System rocket than originally planned, [URL=https://arstechnica.com/science/2018/04/nasa-likely-to-fly-first-deep-space-mission-on-less-powerful-rocket/]Ars Technica reports[/URL]. <BLOCKQUOTE>[i]Although it has not been officially announced, in recent weeks mission planners at the space agency have begun designing "Exploration Mission 2" to be launched on the Block 1 version of the SLS rocket, which has the capability to lift 70 tons to low Earth orbit. Acting agency administrator Robert Lightfoot confirmed during a Congressional hearing on Thursday that NASA is seriously considering launching humans to the Moon on the Block 1 SLS. "We'll change the mission profile if we fly humans and we use the Interim Cryogenic Propulsion Stage (ICPS), because we can't do what we could do if we have the Exploration Upper Stage," Lightfoot said.[/i]</BLOCKQUOTE>
