The software has been updated for Boing to take full remote control of the vehicle and attempt to undock it and bring it back to Earth, where it will land at Space Harbor at White Sands Missile Range, about a hundred miles from my house, around six hours later. If all goes to plan.

One disappointing thing about it is that the thrusters that are the center point of the problem will be lost. Once the capsule is properly oriented for atmospheric reentry, they are part of an assembly that is ejected from the craft and they burn up in the atmosphere. We'll never know precisely what was wrong with those helium thrusters and we'll have to hope that engineers can duplicate the problem with ground-based units and testing.

White Sands is a tough place. It is the world's largest gypsum desert, pull it up in Google Earth, it's pretty cool. Once the Space Shuttle landed in California at Edwards and was being flown back to Florida and landed at White Sands to avoid a storm. And the gypsum just utterly trashed the 747 transporter's brakes! It was supposed to be there for a day or two while the storm abated, it was there for a couple of weeks while a crew was brought out to check out and service the plane! But it was a very scenic backdrop for photos while it was there.


The Dragon capsule that will be flying in late September with Crew 9 has had the final crew decided. The crew has been reduced from the normal four to two to accommodate the return of the two astronauts stranded by Boing. The capsule has been modified with additional seats behind the four crew seats.

One issue has been that of space suits. NASA standard space suits, such as those used for the travelers in the Starliner, are not compatible with the fittings in the Dragon. SpaceX has much more modern suits which are more comfortable and flexible/maneuverable for travel, whereas the NASA suits are better for EVA work if needed. There is one spare SpaceX suit on-hand on the ISS right now that will fix one of the two stranded astronauts, NASA has not revealed which. And Crew 9 will be bringing another suit, presumably for the other astronaut, so everyone will be properly suited for their return in February.

There is a second purpose for the seat reconfiguration of the Dragon capsule. The norm for the ISS is that there is always a Soyuz capsule docked to be used as an emergency life boat in case the station has to be abandoned in the event of an emergency: a fire, a debris collision that can't be avoided, etc. There have been a few times over the station's life where the crew have taken shelter in the capsule. This seat reconfiguration will allow the Dragon to serve as a lifeboat while docked. I have no idea if the Russians are planning a launch to coincide with the departure of the Dragon in February to fill its emergency role.

The booster, B1058, had two historic high-points in its life. It was the first private space flight to launch people to the International Space Station, which is quite an achievement in and of itself. But the thing that has really made SpaceX's name is the reusability of its boosters: 1058 has made NINETEEN LAUNCHES!

Sadly, its nineteenth recovery was not 100% successful.

It landed on its landing craft, as it was designed to do, but a combination of very rough seas and high winds did it in. It ultimately toppled and broke in half, the top half of the booster falling into the sea.

Part of the problem is that it is an old booster, and the recovery ships are unmanned. A manned ship they could have chained down the landing struts and better secured it, but then you're risking human lives if there's problems in the landing. The other problem with the booster's age is that the new boosters have auto-leveling features in the landing struts: in heavy seas and winds, they can compensate for the booster shifting and rebalance it, at least to a certain degree. And 1058 did not have those features retrofitted.

The recovered parts of 1058 will still be of value as the engines will be recovered and everything else will be studied to see how well it held up over 19 launches. Ultimately it will probably be put on display somewhere.

This is absolutely true, but obviously a little more complicated than that. You need to remember that Bezos, like Musk, owns a rocket company, Blue Origin. Theoretically it competes with SpaceX, Musk's rocket company, but let's face it, BO doesn't do much.

Amazon is theoretically going to launch a satellite constellation called Project Kuiper, which is a satellite internet thingie much like what Musk is operating. BO doesn't have the lift capacity right now that actually works, so they're going to another rocket company to get their satellites into space.

And they didn't consider SpaceX - which has the lift and availability right now, and is pretty darn reliable. Bezos and Amazon are being sued by a pension fund, and I'll let the article speak for itself, because the words just make my heart glow when billionaires go after each other: "Shareholders of a pension fund that includes Amazon stock have sued the company, its founder Jeff Bezos, and its board of directors for "breaching their fiduciary duty" as part of a contract to acquire launch services for the Project Kuiper megaconstellation.

The lawsuit, filed on Thursday and first reported by the Delaware Business Court Insider, alleges that in purchasing launches for Kuiper, Amazon failed to consider SpaceX and its Falcon 9 rocket. This was the only prudent choice that would have enabled Amazon to launch half of its constellation by a 2026 deadline, the lawsuit states.

The plaintiffs say that the Falcon 9 costs less than its competitors and has other advantages, such as being available now. Nevertheless, the lawsuit alleges, SpaceX was never considered due to an intense and personal rivalry between that launch company's founder, Elon Musk, and Bezos, who has a competing rocket company in Blue Origin.

"Given these factors, Amazon’s persistent refusal to even consider SpaceX—and the Board’s failure to question its exclusion—lays bare the extent to which Bezos’ personal rivalry influenced Amazon’s procurement process," the lawsuit states."


Pass the popcorn! As much as I hate Musk - and Bezos, for that matter - I'll bet he split a gut when he read about this.

Basically they launched a little milling machine on the end of a robotic arm that had one objective: cut through a piece of composite that simulated the exterior of a rocket's upper stage. The concept being that cutting and welding are very messy processes, but on Earth the debris just falls to the ground, in space it's kind of a problem. The experiment was to do it cleanly in microgravity, and it was a success.

Pretty cool!

It wasn't a 100% success: there were two other samples to be cut through, and that didn't happen and they don't know why.

The experiment was launched on SpaceX early this year and was carried out in May, the results announced Friday.
