SpaceX (general discussion)

Suppose solar man Musk finally go nucleair and put a reactor on it. Not much solar power at Uranus

Not only that, Starship need more powerful engines to get to Uranus fast
Alone round trip to Saturn with chemical engines would take 12 years !

A NERVA nuclear engine would do it, but those don't like methane as remass.
because methane would block up the reactor core with it soot and other decay product

Argon Ion engine like used in Starlink sat, power by nuclear reactor, could do the trip.
but it takes still years for the trip.

To make trip faster you need Rocket engines with specific Impuls of 100000 sec to one million sec
to reduce the trip under a year !

Starship is too small for pulse-Orion to do well

NSWR would be ideal were it not for the heat.

It would be a true 1950's atomic Rocketship then

Fired SpaceX employees sue the company for wrongfully terminating critics of CEO Elon Musk

Eight former employees sued SpaceX and its CEO Elon Musk, alleging that Musk ordered them fired after they challenged what they called rampant sexual harassment, a hostile “Animal House”-style work environment at the company and Musk's role in creating...

The Space Bucket has put out a video about whether or not IFT-5 will be ready to launch in one month's time:

After the most recent test flight, SpaceX is already getting ready for the next with ship heat shield upgrades underway among other prep. Comments from Musk suggest they will be ready in about a month from now with upgraded hardware for flight 5.

While very ambitious, SpaceX does have a few developments going in their favor for a quick turnaround including no mishap investigation from the FAA. That being said, acquiring a possibly modified launch license, replacing a new heat shield, and preparing to launch again is no easy feat. Here I will go more in-depth into new developments that impact Starship’s timeline, how realistic a launch in one month is, what to expect in the coming weeks, and more.

No. Way.

according What about it!
is SpaceX replacing there Heat shield on Starship 30 with dual layer one
under the outer layer of Pica tiles are ablative material tiles installed.

Composites looked to be the initial idea.

Remember, Musk has the old Beal facility---and Beal had one of the largest filament winding machines ever made. I don't know what happened to that---but the composite tank that failed was said to come from Japan---so who knows?

Now, might some ablative recipes also allow them to serve as tile adhesives?

If so, there is only a need to “spackle” missing tiles—not a whole tear down.

Longer tankage and additional propellant will make up for the mass, I trust.

I would like to see Elon look at new tesselations. One known as “the hat” may be of use:

The date I posted above for the Polaris Dawn mission already appears to have been delayed.

The only thing they used from Beal was the land and maybe one test stand.

No, then it is no different than the shuttle and would be labor intensive

I wouldn’t expect the next Starship launch for a little while now, after all we’ve all seen the work they’ve been doing on it recently.

For moment they replace 18000 heat shield tiles on Starship 30 that take some time
Superheavy B12 they installed the Engines, then rollout to Massey site for for Static Fire testing
Also on Launch site they dispose last vertical Tanks, while refurbish the launch pad.

my guess they ready for IFT-5 end July/begin August

It would be a great heat signature, until Merlin exhaust immolates the heat seeker.

It won't be long before they pump out more heat than SuperHeavy measured yearly.

I wonder if AI data center heat generation is not so intense it might ultimately be used for power generation.

I have to wonder whether these are the biggest superfans Elon ever got to date...
