SpaceX welded a valve with the tank full, on a business it is winding down

SpaceX cut open a propellant line inside a fully assembled Crew Dragon, pulled a leaking valve, welded a new one in and flew four people to the space station on Thursday. The oxidiser tank was full of nitrogen tetroxide while the welding happened, and SpaceX needed special permission from the Space Force's Eastern Range to do hot work with it. The company had never done this on a loaded spacecraft before.

“By cutting it out, we physically went in and actually cut the valve out of the line. It was welded in place, and then we actually re-welded a new valve in place.”

The alternative was draining the propellant and taking the ship apart, which would have pushed Crew-13 past the point where it could relieve Crew-12 on schedule. Dana Weigel, NASA's space station programme manager, said the welds, the leak checks and the data all looked good, and no leaks appeared in final preparations.

The business behind the weld

• NASA's total contract for 17 SpaceX crew missions runs to $5.92bn
• The recent extension bought three more flights for $946m, or $315m each
• That is 9.4% below the $348m average across all 17, so the newest flights are the cheapest
• SpaceX has nine Crew Dragon flights left in the backlog and plans to retire the vehicle around 2030
• The company committed $100bn to a single Louisiana spaceport in August, 16.9 times the entire NASA crew contract

Put the last two lines together. Ars Technica lists what SpaceX is prioritising instead: Starlink, Starship and orbital data centres. The first two have been obvious for years. The third is the one our readers have been watching, and it explains why a $5.92bn human spaceflight programme now sits in the legacy column next to a $100bn spaceport.

Orbital compute is the competing claim

We covered the orbital data centre case twice in August. Starcloud raised $250m to put compute in orbit as launch costs fell, and we went through what SpaceX's own orbital AI data centres would do to the e-waste problem, since a dead server in low Earth orbit cannot be recycled.

The pitch for orbital compute is power and cooling: continuous sunlight, no grid connection to negotiate, no county water supply to argue over. Those arguments got stronger through 2026 as terrestrial data centres ran into exactly those limits. A company that launches cheaply and at volume is the natural supplier, and the Falcon 9 line SpaceX plans to retire around 2030 is the one that made launch cheap.

What it means for a crypto desk

SpaceX trades now, and not only on public markets. Bybit listed options on SpaceX stock perpetuals in August. Leverage comes with the instrument, and so does the ability to take a view from a crypto account on a company whose revenue mix is shifting from government contracts toward broadband and compute. Respect the engineering on the Crew-13 weld. The capital allocation behind it is what moves the number.

Gerstenmaier declined to say whether there is a hard cutoff for Crew Dragon flights to NASA, noting only that flights 15, 16 and 17 were just awarded and that the focus is getting the most out of them. The extension may be the last. Nine flights remain, the ISS is funded through at least 2030, and Boeing's Starliner is still the alternative NASA keeps hoping to have.
