NASA delays next flight of Boeing's alternative to SpaceX Dragon

Well ... Boeing got themselves into the perfect storm. They need this flight to work right, after the catastrophic first attempt. But the longer they wait to get things right, the more eyebrows will be raised. They need a good flight, now.

But they do not determine the schedule - it's determined by NASA, which has about a thousand problems of itself right now, and cannot afford to screw up either.

I do not envy anyone in that chain of delivery right now.

cbanek•10h ago
"Musk, who has been engaged in a high-profile feud with US President Donald Trump, on Thursday threatened to decommission the Dragon before later saying the spacecraft would stay in operation."

Interesting timing.

tonyhart7•8h ago
he got himself on gov watch list after that tweet for sure
AStonesThrow•7h ago
Yeah I heard they're gonna start live-tracking his private jet flights
TheOtherHobbes•7h ago
He was never going to decommission Dragon. That was just playground petulance.

There's nothing Putin enjoys more than watching two senior underlings fighting like rats in a sack.

The US space and science programmes are useful collateral damage in this.

Propelloni•7h ago
I'm usually not one to defend Elmo, but it was a response to P47 threatening to defund SpaceX. It's like watching children. Poor USA, poor us.
Hamuko•7h ago
Wasn't it Musk that was calling for a smaller and leaner government?
wtcactus•5h ago
DragonX is the smaller and leaner government.
mcmcmc•20m ago
No, it’s a private for profit corporation.
rlt•10m ago
By my estimate, SpaceX has saved the US government 10s of billions by reducing launch costs with Falcon 9, developing Dragon, Starlink, etc.

One thing I wanted to ask somewhere, Jared Isaacman was NOT a Musk pick, or am I not right?
lupusreal•4h ago
He was.
VectorLock•4h ago
They pulled Jared Isaacman because it was revealed he had donated to Democrats.
lupusreal•4h ago
That was their excuse. But they probably knew it already upfront, and of course Trump himself has done so and obviously knows that rich people donate to both parties just to cover their bases and that it means relatively little.

I think it's more likely that Jared was pulled at the suggestion of some staffers that never liked him or Musk in the first place but weren't able to get their way with Trump as long as Musk was still around.

kranke155•3h ago
Basically they pulled a fast one on Musk, who believed that with his giant (300$ million give or take) donation would be able to get his preferred candidate to NASA.

The fact that he was quite competent and generally liked doesn’t matter to Trump, who seems set on defunding NASA and having someone there who won’t complain.

rapsey•3h ago
They knew that from the start. He pretty much said himself it was a retaliation in the Musk/Trump situation.

That's pretty amusing, considering Trump spent decades as a NY Democrat.

That was a pretty dumb tweet as it gives Trump all the ammo to put SpaceX under close government scrutiny and/or make plans to nationalize it, or whatever whimsical thing he can think of to hurt Musk.

They say “the only US alternative”, which is true, but it’s not the only alternative - nasa paid for seats on Soyuz for many years, and I’m sure they could go back to doing the same. Perhaps China would be willing to sell seats on their launches. Maybe India will be in a position to offer human launches to the U.S. fairly soon - should be up and running by 2027, and they seem to hit their objectives most of the time.

Cooperation with roscosmos seems to have been largely unimpeded by Russia’s political and military actions over the years, so these all seem like realistic possibilities.

Yes, it will be a shame if the U.S. has no launch capability of their own, but short term partisan political thinking is much more important to the electorate than long term national strategic interest.

sigmoid10•6h ago
NASA still cooperates heavily with Roscosmos and American astronauts regularly fly in paid Soyuz seats. The latest one is Johnny Kim who launched in late April on Soyuz MS-27 from Baikonur and will stay on the ISS until december. And Christopher Williams is already scheduled for the next Soyuz mission.

China on the other hand will probably never happen because of the general political climate in the US and this administration in particular.

lupusreal•4h ago
Congress has forbidden NASA to cooperate with China for many years. It's been law since 2011: https://en.wikipedia.org/wiki/Wolf_Amendment

Also I believe that Russia isn't being paid for astronauts to fly on Soyuz. Instead, cosmonauts fly on Dragon. It's a like-for-like exchange which is mutually beneficial (both countries need the other's cooperation to keep the ISS operational, so these exchanges ensure that can continue if either Soyuz or Dragon are grounded for some reason.)

imtringued•3h ago
Correct. The US paid for the Soyuz flights that they owed Russian astronauts, because they had no means of bringing them to the ISS.
throe83949449•1h ago
My understanding is Russia wants out of ISS cooperation. Whatever contract there is, it will expire soon, and may not be extended.

> American astronauts regularly fly in paid Soyuz seats

It's a seat swap arrangement, no money is exchanged.

It seems likely that the Pentagon will soon force SpaceX to merge into another contractor, most likely Boeing or Boeing's largest rival, Lockheed-Martin.

xoa•3h ago
>It seems likely that the Pentagon will soon force SpaceX to merge into another contractor

I'm sorry but what? SpaceX is private, not public, and regardless the Pentagon has zero power to force any such thing. It's making gobs of money and growing pretty fast (around $12 billion revenue this year, prediction is/was ~$15.5 billion so something like a 30% YoY increase) with most of that from Starlink, then commercial launch and gov launch. It launches more mass to LEO then everyone else on the planet combined by a long shot, for far far less $/kg. And it doesn't seem to be slowing down at all. There would be zero interest on either side in a merger, nor is there any particularly good national security argument for it.

The real plan is the same as it's always been: have a reasonably vibrant set of multiple motivated, competitive commercial launch providers. That'll take years more but is by far the better long term solution, and there are plenty of promising options, like Rocket Lab (their Neutron medium lift rocket is apparently close to maiden flight) and Blue Origin (who finally at last seem to have been shaken up and are actually launching rockets and making engines). Old Space wants out of the launch business, which is why ULA came to be at all.

People are also tossing around "nationalization" as if it's some quick fix too all of a sudden, but nationalization doesn't nullify the 5th Amendment (or 1st). The US government would have to come up with the arguably hundreds of billions of dollars present value of SpaceX, at a time of deep budget cuts, debt worries, and high interest rates. It would also have to win a set of massive lawsuits by an extremely well funded opposition about all aspects of the mess that would drag on for years. And a lot of the value of SpaceX is in its institutional knowledge, culture, key people etc etc. Nationalization could not prevent key people all bailing and destroying much of the capability. This would all be hugely disruptive, at a critical juncture, and a big political mess too. It's concerning how blasé folks can get about expensive, complicated big deal gordian knots.

rapsey•3h ago
> The real plan

Ugh that is being way too generous. A private space industry exists despite their plans not because of them.

xoa•2h ago
>A private space industry exists despite their plans not because of them.

No, this is completely opposite to reality. The current US private space industry was absolutely the result in large part of a rare modern spell of good policy decisions and sustained support (and absolutely yes, a certain amount of luck, but it's important to create conditions where luck can snowball). Support that has paid off in spades and now is self-sustaining sure, but that's a good thing and doesn't change the vital nature of the bootstrapping period. Commercial Cargo and Commercial Crew were critical, as was opening up national security launches then actually embracing it. Multiple providers is now an explicit goal of the DOD and they have repeatedly acted to support it, from awarding NSSL launch contracts with an eye towards which player really needed them to stay in business to being willing to take on more risk for less critical payloads. It hasn't been a short road or one without bumps and conflicting interests, and it's almost a miracle it happened at all given Congress' general shortsightedness and desire to use space almost purely as a vehicle for pork regardless of efficiency, but happen it did (ironically thanks in significant part to Boeing [0]). The contrast with the slow, anemic and visionless efforts of the EU during the same time period is striking.

Putting SpaceX under the CEO of Boeing would make SpaceX as bad as Boeing, not Boeing as good as SpaceX.

Also, it's still America. Good luck to anyone trying to "force" SpaceX, a private company, to do anything they don't want.

"it's still America"

Is it?

smt88•21m ago
Trump admin has suggested using wartime powers to nationalize SpaceX. They're already using those powers for deportations.

I don't know if they seriously want to do it, but whether they can do it is up to a highly sympathetic SCOTUS.

rlt•7m ago
They’re in a pissing match. The relationship between SpaceX and the federal government is mutually beneficial. I would be surprised if either follows through on their threats.
