No Plans for Second SLS Mobile Launcher
One question I’d like to see answered, that as far as I know has never been asked or commented on: how much time is needed between EM-1 and EM-2 for everything else except the Mobile Launcher?

NASA recently began talking about some contingency planning for potential Commercial Crew delays, and the end-of-ISS discussion is heating up.
The Commercial Crew program—NASA, SpaceX, Boeing, and more—went in front of Congress to discuss the current status of the crew launch systems in development. Concurrently, the GAO released a report warning that more delays are likely, and could put NASA in a tough spot. I share some thoughts on the matter and talk through what is likely to happen this year.
This requirement grew out of concerns about SpaceX and how frequently they update the design of Falcon 9. And from where NASA stands, it’s a totally valid concern and requirement. The problem is that it has very blatantly only ever been applied to SpaceX.
The language used here is imprecise, so it’s tough to draw conclusions, but “summer” implies a slip for the uncrewed test flight of Dragon 2, currently scheduled for April.
A special preview of the MECO Headlines shows: Elon Musk kinda-sorta-maybe announces the Falcon Heavy demo payload, Russia and China carry out successful military launches, NASA announces some very interesting NextSTEP-2 contracts, OA-8E Cygnus departs ISS, and SpaceX’s SLC-40 is back, baby!
If Virgin Orbit delivers on their stated cost and performance goals for LauncherOne, they’ll put Minotaur I out of work in a hurry. But the market is still without any vehicles that put the heavier Minotaurs—Minotaur-IV and Minotaur-C specifically—in any danger. Terran 1 could be the first truly commercial launch vehicle to take on those heavier Minotaurs.
Chris Gebhardt of NASASpaceflight published a nice article last week on Blue Origin’s ongoing New Glenn work. He also had this great little nugget of info to share regarding the ship that New Glenn will land upon.
SES gives us a preview of their new GEO strategy (which may be a harbinger of the future), Orbital ATK tests a new composite case to be used for their Next-Generation Launcher and future SLS boosters, NASA approves the use of previously-flown Falcon 9 first stages, and SpaceX sets off some LOX fireworks down in McGregor, Texas.
Chris Gebhardt wrotea fantastic piece over on NASASpaceflight.com on SLS, Europa Clipper, EM-2, and its Mobile Launcher(s?). The Mobile Launcher is being finalized in its SLS Block 1 configuration for EM-1, after which it will need to be converted for SLS Block 1B—a 33-month process, and NASA’s Aerospace Safety Advisory Panel has some interesting concerns.
