NASA is jealous of how big Musk’s rocket? Sounds like high school stuff..
Space dot com is a tiresome website more concerned about their business model than about reporting space news -- which is in part because there isn't really all that much space news from day to day. If they had any sense, they'd serialize transcripts of events like the video I linked up there.
Bridenstine was just doing his job, part of which is to show how responsibly NASA is now using taxpayer money, now that muzzie outreach and global warming horse**** is out of the agency. If anything, he and Musk should get a room, geez. :^) It's no wonder though that Musk gets pissed off, although I think he handled it well, must be new meds or aromatherapy or something.
