Maybe they want to air start an RS25? Wonder if anyone had ever thought of that
No, different angle. The other engines should be visible.
Seems like there’s atleast one more engine to me...

How does lander handle boiloff at gateway while waiting months for crew mission

Quote from: spacenut on 10/25/2019 06:42 pmSo if Boeing wins the bid, they will have to launch two SLS's to get astronauts in Orion and the lander to the moon by in space docking. Wow, a moon landing for about $3 billion or more per landing. Not counting the LOP-G station. This is way expensive to use the SLS. If you're that confident the bid will be financially uncompetitive, then you should have nothing to worry about. It's not like there are other costs beside launch costs that factor into bidding a lunar lander. Development of new technology is free as we all know, and there is no possibility that a two-stage SLS-launched design might be easier and cheaper to develop than a three-stage commercially-launched design, or that those cost-savings might be enough to offset the higher launch costs, especially since we're only considering SLS marginal costs.

In all seriousness, do you think Boeing is stupid? If they didn't think an SLS-launched bid was competitive they wouldn't propose it.
There is nothing stupid about Boeing proposing this. It stands a good chance of becoming another of the company's cash cows, which is exactly what its shareholders Richard Shelby wants.

U.S. Sen. Richard Shelby, R-Tuscaloosa, on Thursday ripped top Pentagon officials, including Defense Secretary Robert Gates, for their handling of the Air Force tanker competition, accusing them of tilting the selection criteria in favor of Boeing Co."One would think that our Air Force's top priority would be to ensure that our men and women in uniform have the best, most capable equipment. Clearly that is not the case," Shelby said in a speech on the Senate floor.

I promise you, nothing coming out of the space exploration domain is a cash cow.Don't believe me? Look up the shareholder reports. Revenue from space exploration is in the noise.
