SpaceX (general discussion)

Perhaps four Starships are bc they are working on production techniques in parallel with design validation. Remember the mass they believe is required to send to Mars.

Do we know what version of engines were used on this last flight?

Version 2, 3 is in development. Not all the Starships will fly, 26 seems to be out to pasture and 28 may be the next to be stacked.

cryogenic testing at Massey's.
follow by engine integration.
Then on suborbital launch site spin test follow engine spin-prime and static fire testing.
those test...

...Now something happing at Robert Road at KSC.
parts for second Launch tower are moved from Florida to Texas Starbase.

Were SpaceX will build the Second launch komplex ?
in older FAA papers by SpaceX, they planned to build close next first Launch Pad

Loss of telemetry is not a loss of ctrl. You don't blow up your TV set because your home wifi shut down.
SpaceX should provision for a redundant line of sight communication chanel during ascent.
 
That an Im pretty sure losing telemetry on the acsent stage in an unmanned vehicle is generally a near instant blow it deal if you cant re acquire it after X amount of time.

Know that happened to several Nasa and Russia rockets in the pass.

Loss of telemetry doesn't mean there weren't redundant pathways, it just means they all failed. It could also mean that something failed in a critical system somewhere that redundancy either isn't possible or itself failed.

There could several reason what happen
but that loss of telemetry indicate, something serious happen see lost of LOX before SECO
Either in Starship 25 electrical system or communication was interrupted as hull went RUD
i hope that SpaceX make public what happen in last minute.


This example is Upper stage failure from Europa Rocket
First test of Astris stage ende in lost of telemetry during stage separation from second stage.
It was quite intriguing why it happen:
The German had not isolated electric contact, since Stage would operate in vacuum of space.
What they not account for was the explosive bolt on second stage they produce gas!
This gas filled the interstage and back oft the third stage Astris
What produce a short-circuit in one electric circuit: the Flight Termination System...

No, not true.

Loss of telemetry is not a reason for FTS activation. There is no feedback to the vehicle. Launch vehicles are autonomous, there is no ground control.* There are no receivers on launch vehicles.#
AFTS would have signaled that it went off or telemetry showed a signature during loss of signal
Even with old school FTS, if there still was radar lock and the vehicle was still on course, there was no reason to destruct.

* except those with old school FTS and need a range safety officer to initiate destruct.
# except GPS and those with old school FTS.
 
TheSpaceBucket has just put out a video concerning wether or not the Lunar Starship will be available for Artemis III:


Yesterday, the GAO, also known as the U.S. Government Accountability Office, released a 47-page report highlighting some of the major concerns regarding the plan to return humans to the Moon. One area in particular that the report focused on was the Starship Human Landing System and the large amount of work that SpaceX still needs to complete.
Click to expand...
They are concerned that Starship development in conjunction with a handful of other projects will delay the 2025 landing date by at least a few years. On the other hand, the report also gave new insight into the progress of a lunar Starship and the large amount of work that has already been completed. Here I will go more in-depth into what this report says, the state of a lunar Starship, some of the biggest upcoming challenges, and more.

It all depends on the next test goes and how successful it is as to whether the Lunar Starship would be avaiable for Artemis 3.
 
Fact is that NASA budget is heading toward a brickwall, threatening Artemis III. Surprise surprise, SLS is no longer a money pit but a black hole.
As for SpaceX, no such issues (obviously, with the richest man in the world at the helm) but another massive obstacle: on orbit refueling of Starship HLS.
SH-Starship seems on the right way to a fully reusable orbital mission, but on orbit refueling is another step entirely: a big one. Rapid fire Starship tankers, for a start. Controlling boil off.
 
Not to rain on any parades but there won't be three Starship flights in December. I doubt there will be even one. And I will be surprised if the Falcon Heavy launch doesn't slip into January. On the other hand, more than 5 Falcon 9 launches wouldn't surprise me.

There still 5 launches planned for December 8/9/10 and 14.
and even if they not launch them

91 launches in one Year is impressive for Private Company
let see what the competition dit:
China = 53
Russia = 16
RocketLab = 9 (one failure)
ArianeSpace = 2 Ariane 5 (last one) 1 Vega-A (last one)
ULA = 2 Atlas
Blue Origin = ZERO LAUNCHES

It appears that one of the tests to be carried out on the IFT-3 flight is propellant transfer demonstration, from TheSpaceBucket:


As SpaceX continues to prepare for Starship’s next launch, we are learning more about its flight profile and specific mission plans. This includes new reports that the third flight will include a propellant transfer demonstration. That would be a significant step in Starship’s development and also require the vehicle to successfully enter its coast phase around the globe.
Click to expand...
This would also be an important development toward the vehicle’s lunar lander progress which has been a topic of concern lately. All this being said, the propellant transfer planned for the next flight is likely a lot simpler than the future plan with multiple vehicles in orbit. Here I will go more in-depth into the next flight’s plan, the propellant transfer process, vehicle progress, and more.

SpaceX has just put out this short video concerning IFT-2:


On November 18, 2023, Starship successfully lifted off at 7:02 a.m. CT from Starbase on its second integrated flight test.
Click to expand...
While it didn’t happen in a lab or on a test stand, it was absolutely a test. What we did with this second flight will provide invaluable data to continue rapidly developing Starship.
Click to expand...
The test achieved a number of major milestones, helping us improve Starship’s reliability as SpaceX seeks to make life multiplanetary. The team at Starbase is already working final preparations on the vehicles slated for use in Starship’s third flight test.

Congratulations to the entire SpaceX team on an exciting second flight test of Starship!

IFT-3 is NET December 2023. FH is ready to launch it’s just waiting on the weather forecast.
