If the software can't be changed, is there a way for an astronaut to go inside the starliner, depart from the ISS, then hop back to the ISS using an eva suit?

The idea is to change the software to make it possible for the capsule to return without crew. The change of software is possible and what they are doing, it just take some time. The software to do so is already availabe as in previous uncrewed flight.

EVA suit or IVA suit alone is not enough to "fool" the software, you need to have some devices in the suit to emulate a human so the safty check procedure can pass and be activated and remain activated before the undocking and probably afterwards too so the computer thinks everything is working. The emulation includes oxgen consumption and circulation, body heat to stimulate temperature regulation, simulate moisture from breath and sweat, heart beat etc. None of them exists on ISS. So updating the SW is the only way.

If you are thinking of someone wearing EVA to get into the capsule, initiate a departure then "fly" back to ISS, it won't work because EVA is not compatible to IVA interface to the capsule and lacks the kind of emulation devics above even if we believe someone can do a "Gravity" movie stunt.

Given how Boeing engineers coded the MCAS software (check the readings of only one of the angle-of-attack sensors), I am highly doubtful the program in Starliner checks all those parametres. The most it checks is there is a suit hooked up to the spaceship within the cabin.

Boeing Starliner capsule lands back on Earth, without astronauts, to end troubled test flight (video)​


Starliner's long space odyssey is over.

The Boeing capsule, named Calypso, returned to

early this morning (Sept. 7), touching down in the New Mexico desert at 12:01 a.m. EDT (0401 GMT; 11:01 p.m. local time on Sept. 6).

"Great landing of Calyspo!" NASA astronaut Suni Williams said on the agency's webcast. "I don't think that could have gone better."

The landing was long-delayed, coming more than three months into an orbital mission originally expected to last about 10 days. And, while

launched with two NASA astronauts aboard — Williams and Butch Wilmore — nobody rode it home.

It wasn't supposed to end like this.

Pretty amazing if it happens. At one time ULA was the only choice you had for space launch in the USA. SpaceX killed it. I expected Blue Origin to get ULA eventually.

I think SNC/ULA talks are ones of last resort. I had serious doubts about Blue Origin buying ULA: Vulcan wouldn't give anything to BO with BO flying their rocket relatively soon and...BO has been burning Bezos' cash without much income.

New Glenn is at risk of further delays NASA pulled the ESCAPADES small sats, btw.

You are mostly correct about the ULA and SpaceX. A dependency on Russia for engines also did in the Atlas V. The world changed in tech and geopolitics.
