SpaceX (general discussion)

That said maybe the ASDS is due to the three second stage burns.

It looks as if something is being dropped of at some point from the mission profile. Also someone has pointed out on NSF not even Globalstar has acknowledged this mission.

Yep was something else was on this launch especially the way the coverage of the second stage resumed ‘half way through’. Dispenser being used apparently looks like Starlink but different.
 
Seems possible that the unknown payload may have been a classified Starlink, seemingly there was something of the sort on Transporter-3. These maybe related to their work with the SDA. If I am understanding it right they maybe classified satellites using the Starlink v1.5 bus.
 
Confirms four classified payloads were on the launch. USA 328-331. They'll probably be like Transporter-3 was believed to be four classified Starlinks. These are not SDA satellites.

Space-Track confirms the presence of four secret payloads on the Globalstar Falcon 9 launch - USA 328 to USA 331, catalog 52889 to 52892, orbital data not available. One piece of debris, probably a Starlink-style tension rod?

Stacking has begun on Launch Pad 39A

if they build that Launch Tower with same speed like on Starbase
its ready in October 2022 for first Launch
 
I'm interested to see if they duplicate the launch "ring". Elon had said he thought it was way overbuilt, expensive, and complex. It does look cool though. :D
 
One thing about these videos that just doesn't make sense, landing and taking off right next to your habitat like it's showing. Plus, how would all the infrastructure get built before hand anyway ?
 
WASHINGTON — NASA has found a new ride for a small lunar orbiter mission that will allow the spacecraft to avoid a two-year wait for its launch.

In a June 21 presentation to the Planetary Science Advisory Committee, Lori Glaze, NASA planetary science division director, said the Lunar Trailblazer mission will now launch as a secondary payload on the second lunar lander mission by Intuitive Machines, called IM-2 and part of NASA’s Commercial Lunar Payload Services (CLPS) program. That mission will launch in about a year, she said.

Lunar Trailblazer was previously manifested to launch as one of several rideshare payloads on NASA’s Interstellar Mapping and Acceleration Probe (IMAP) mission, currently scheduled for no earlier than early 2025. That schedule was driven by development of IMAP itself, with Lunar Trailblazer expected to be completed by early 2023.

Dish looks to be hogging bandwidth…and I have read of concerns with Tesla plants. 5G is said to interfere with Starlink in the US

A bit of paint should not matter-yet it makes this more real to me. A Nova class LV at last...I still half think I'm dreaming.

Well, a SMALL Nova class. When I think "Nova" I think of things like L6H engines that produce 24,000,000lbs thrust each, then stick four of 'em on your rocket. :)

Didn't SDA have a contract with SpaceX to build four demonstrator sensor layer satellites using a starlink bus? Could this be related?

EDIT: actually I think this might have been an MDA contract.

Not Quite
Starship/Superheavy carry 100~150 metric tons in low earth orbit, or 220000 lb to 330000 lb.
A Nova Class Rocket was design to carry ONE MILLION POUNDS into Low orbit, that is 453,59 Metric tons payload
or 4 to 3 times of Starship, but Musk talk about option of a 18 meter diameter Starship/Superheavy
What is actually a Nova Class Rocket !
I wonder how the Raptors 3 Engine will look like to power that beast...

SpaceX has submitted new FCC filings for Starlink communications during the Starship orbital test flight. Multiple terminals will be mounted on the ship and the booster to ensure clear views with the constellation through all phases of flight. https://apps.fcc.gov/oetcf/els/repo...le_num=1169-EX-ST-2022&application_seq=116809

Flight profile details:
- Booster will either do a partial return and land in the Gulf of Mexico or do a full return with a catch attempt
- Ship will reach about 250 km in altitude, then powered landing in the Pacific

Starlink will allow "high-data rate communications" and remove telemetry blackouts during reentry.

Tim Dodd second Video on Raptor 2
Raptor 1 vs Raptor 2 what we have to except for Raptor 3
View: https://www.youtube.com/watch?v=E7MQb9Y4FAE


correction on video Dodd and Musk assumption there is not inline powerhead configuration rocket engine.
There is a rocket engine with Vertical Turbo pump assembly
during 1963 to 1973 Germany tested high Pressure rocket Engine HDTW by MBB
the preburner and combustion chamber is one and same with turbo pump drive turbine in it !!!
to radical for ELDO, ESA or NASA

Yeah, actually not good. Team is assessing damage.

Cryogenic fuel is an added challenge, as it evaporates to create fuel-air explosion risk in a partially oxygen atmosphere like Earth.

That said, we have a lot of sensors to detect this. More later.

Elon, would it be possible to maybe burn/evaporate the leaks caused before ignition? I guess space shuttle used to do this, they used to setup small sparks under the shuttle's engine section & burn off all the Hydrogen leaks that may have happened before ignition ...

That is one of the things we will be doing going forward.

This particular issue, however, was specific to the engine spin start test (Raptor has a complex start sequence).

Going forward, we won’t do a spin start test with all 33 engines at once.

Now, N-1 had plastic fuel tanks. Had composites been used-would this have been a bigger blast?

Why would it be? It's akin to asking why Delta IVs don't go up, Hinderburg style, at launch.
 
Delta IV lox tanks are metal. LOX in carbon is sensitive-if the kicked loxcicle story during Apollo is true.
 
A passing thought-have Boring Co build tubes that are vacuum filled to draw off fumes? Some tube extensions? curtain the milkstool...nitrogen cascade deluge...blow-off doors...limit oxygen, etc.
