Zitat Ellie in Space 🚀💫@esherifftv Issue was with launch and catch tower, not booster
“Following a nominal ascent and stage separation, the booster successfully transitioned to its boostback burn to begin the return to launch site. During this phase, automated health checks of critical hardware on the launch and catch tower triggered an abort of the catch attempt. The booster then executed a pre-planned divert maneuver, performing a landing burn and soft splashdown in the Gulf of Mexico.” 3:27 AM · Nov 20, 2024

Rocket Starship
Payload (⚀ = CubeSat) Stuffed banana
Flight number Flight 6
Operator SpaceX
Remarks Sixth Starship orbital test flight. A stuffed banana served as the Zero-G indicator, becoming Starship's first payload, though it remained within the vehicle for the duration of the flight.[210]
Zitat The toys, which are generally tethered to a wall or other anchor, begin to float about the cabin when the launch phase of the flight ends, indicating that the crew is in zero-g.
The custom began on Russian spaceflights, dating back to the first launch of a human into space in 1961. Soviet-era cosmonaut Yuri Gagarin carried a small doll with him on his Vostok 1 mission to watch it float. Since then, the zero-g indicators have varied from homemade dolls to off-the-shelf, commercial toys.
SpaceX adopted the practice with its first test flight of the Crew Dragon spacecraft, launching a plush doll of the planet Earth on its 2019 Demo-1 mission to the space station. The Celestial Buddies' Earth was then joined by a sequined apatosaur, "Tremor," which was chosen by the sons of Demo-2 crewmates Bob Behnken and Doug Hurley.
Halten wir fest: der Grund, warum die Startstufe nicht aufgefangen worden ist, lag an einem Problem mit dem Startturm. Wenn man sich den Videostream nach dem Start genau ansieht, erkennt man, daß die Antenne an der Spitze um etwa 45° nach hinten gekippt erscheint, als ob sie der Druckwelle nicht standgehalten hätte.
Zitat Elon Musk@elonmusk The biggest technology challenge remaining for Starship is a fully & immediately reusable heat shield. Being able to land the ship, refill propellant & launch right away with no refurbishment or laborious inspection. That is the acid test. 3:58 AM · Nov 20, 2024
Um dieses Problem auszuschließen, gibt es eine einfache Lösung. Direkt neben dem ersten Startturm ist im Sommer ein zweiter errichtet worden (sechs Gitterrost-Kuben, die aufeinandergestapelt worden sind, mit je 20 m Kantenlänge), der künftig zum Auffangen des Starship dienen soll. Mit einem dritten Startturm stehen dann für jeden Start zwei unbenutzte zur Verfügung, die nicht in Mitleidenschaft gezogen sein können.
Zitat Elon Musk@elonmusk The Two Towers
Zitat SpaceX@SpaceX·Aug 21 Second launch tower stacked as the newest addition to Starbase
Zitat Construction of a second launch tower began in May 2024,[109] near the former location of the suborbital launch site.[110] The first tower sections arrived on May 14, 2024.[111] Foundation work for the second tower was spotted on May 25, and concrete pouring began in June. Structure installation began in mid-June,[112] with the tower's stacking being completed on August 21.[113]
Zitat Space Sudoer@spacesudoer·1h As much as I hate asking this here, I couldn't resist. What caused the catch abort?
Elon Musk@elonmusk Lost comms to the launch tower computer. Catch would probably still have worked, but we weren't sure, so erred on the side of caution. 7:41 PM · Nov 20, 2024
Zitat A day after SpaceX launched its Starship rocket for the sixth time, the company received good news from the Federal Aviation Administration regarding future launch operations from its Starbase facility in South Texas.
In a draft version of what is known as an "Environmental Assessment," the FAA indicated that it will grant SpaceX permission to increase the number of Starship launches in South Texas to 25 per year from the current limit of five. Additionally, the company will likely be allowed to continue increasing the size and power of the Super Heavy booster stage and Starship upper stage.
"FAA has concluded that the modification of SpaceX’s existing vehicle operator license for Starship/Super Heavy operations conforms to the prior environmental documentation, consistent with the data contained in the 2022 PEA, that there are no significant environmental changes, and all pertinent conditions and requirements of the prior approval have been met or will be met in the current action," the federal agency stated in its conclusion.
The 158-page document makes for interesting reading, and it details the extent to which the FAA and other agencies reviewed air quality, climate, water, noise, cultural, wildlife, and other impacts. In all of these areas, the federal agency concluded that the mitigations SpaceX undertook as part of the 2022 environmental review process are sufficient to account for the increase in its Texas launch activities.
And there will be significant impacts. For example, the number of large trucks that deliver water, liquid oxygen, methane, and other commodities will increase substantially. According to the FAA document, the vehicle presence will grow from an estimated 6,000 trucks a year to 23,771 trucks annually. This number could be reduced by running a water line along State Highway 4 to supply the launch site's water deluge system.
SpaceX has made progress in some areas, the document notes. For example, in terms of road closures for testing and launch activities, SpaceX has reduced the duration of closures along State Highway 4 to Boca Chica Beach by 85 percent between the first and third flight of Starship. This has partly been accomplished by moving launch preparation activities to the "Massey's Test Site," located about four miles from the launch site. SpaceX is now expected to need less than 20 hours of access restrictions per launch campaign, including landings.
If finalized, this environmental assessment will give SpaceX the regulatory greenlight to match its aspirations for launches in at least 2025, if not beyond. During recent public meetings, SpaceX's general manager of Starbase, Kathy Lueders, has said the company aims to launch Starship 25 times next year from Texas. The new regulations would permit this.
Additionally, SpaceX founder Elon Musk has said the company intends to move to a larger and more powerful version of the Starship and Super Heavy rocket about a year from now. This version, dubbed Starship 3, would double the thrust of the upper stage and increase the thrust of the booster stage from about 74 meganewtons to about 100 meganewtons.
Zitat The upper stage Starship spacecraft reached an initial apogee of 190 km (120 mi) and a perigee of 8 km (5.0 mi) at a 26.2 degree orbit, marking the first time Starship has had positive perigee. At 22:37:46 the Ship successfully conducted the first Raptor engine relight in the vacuum of space which raised the apogee to 228 km (142 mi) and the perigee to 50 km (31 mi).[2] Starship reentered the atmosphere at 22:47:13, and at 23:05:24, Starship performed a controlled splash down in the Indian Ocean.
Zitat Starship flight 6 was launched on Nov 19. The booster was waved off from a recovery attempt (due to a tower issue) and made a divert burn to a water splashdown. The ship reached an estimated 8 x 190 km x 26.2 deg orbit, the first time Starship has had positive perigee. A Raptor in-flight restart during descent raised the orbit to about 50 x 228 km, followed by entry over the Indian Ocean and splashdown on the ocean surface.

Stichwort Fahrplan. Um mal das vorlegte Tempo zu verdeutlichen: die nächsten Starts von SpaceX stehen für den 24., 25., und 26. November auf der Agenda; für den 24.11. sind isg. 4 Starts vorgesehen: zusätzlich noch einer der "Electron" von Rocket Lab auf Neuseeland und zwei chinesische von Jiuquan. Für den 2. Dezember steht der nächste Launch der ESA auf dem Plan: der insgesamt dritte Start einer Vega-C von Kourou und der erste seit dem Scheitern des 2. Einsatzes im Dezember 2022 (der Erstflug war im Juni 2022); es ist der 22. Start einer Rakete der Vega-Klasse überhaupt seit dem Erstflug im Februar 2012 (in der Entwicklung befindet sich die Reihe seit 1998). Zum Vergleich: SpaceX hat mit der Falcon 9 allein in diesem Jahr bislang 111 Starts durchgeführt.

Zitat Unter Ullage (englisch u. a. für „Freiraum“, „Füllstand bis Tankdecke“) versteht man in der Seeschifffahrt den freien Raum bzw. den gemessenen vertikalen Abstand zwischen der Oberfläche einer Flüssigkeit in einem Tank (Füllstand) und dem oberen Abschluss des Tanks.
In der Raumfahrt ergeben sich durch Ullage besondere Herausforderungen. In Mikrogravitation oder Schwerelosigkeit ist der Flüssigtreibstoff von Raketen nicht wie auf der Erdoberfläche am unteren Ende der Tanks, wo der Treibstoff entnommen wird, konzentriert. Das erschwert es, eine konstanten Zufuhr von Treibstoff zu den Triebwerken zu ermöglichen, die Raketentriebwerke oftmals benötigen. Es gibt verschiedene Lösungen für das Problem, etwa Ullage-Motoren, die kurz vor dem Start eines Triebwerkes Schub ausüben und durch die Beschleunigung den Treibstoff in eine Richtung des Tanks drücken. Sobald das Triebwerk gestartet ist, übernimmt es diese Funktion. Ullage-Motoren können z. B. kleine Feststoffraketen oder das Reaction Control System (RCS) eines Raumschiffes sein.
Der Hitzeschild des Starship besteht aus 18.000 sechseckigen Kohlefaserkacheln von gleicher Größe, mit einem Durchmesser von 24,13 cm und einer Dicke zwischen 2,5 und 7 cm; für Flug 6 ist die Zahl um 1200 reduziert worden. Die genauen Details sind nicht öffentlich bekannt. Ein kurzer Überschlag ergibt, daß der bisherige Hitzeschild eine Gesamtoberfläche von 20m² aufweist. Legt man das Gewicht der HRSI-Kacheln (wie sie für den Shuttle zur Anwendung kamen, mit einem spezifischen Gewicht von 0,25, würde sich ein Gesamtgewicht von 5 t ergeben; wenn man die Kohlenstoffverbundfasern (TUFROC) nimmt, die bei der X-37 verwendet werden (0,4), wären das 8 Tonnen.

Zitat The Launch Pad@TLPN_Official STARSHIP FT7 UPDATE! #SpaceX #Starship #Flight7 According to new documents filed by NASA to the FAA; SpaceX is targeting NET January 11th, 2025 for Starship Flight 7; and NASA5, a Gulfstream V will be used to observe the reentry of Ship 33 when it enters over the Indian Ocean.
NASA is requesting a expedited review and consideration to accommodate multiple flights over the Gulf of Mexico and Southwest Texas beginning as soon as December 7th, 2024 to calibrate the onboard sensors that will be used to image the peak heating of SpaceX’s Starship 7 during re-entry.
This new information now confirms the seventh flight of Starship will be another suborbital flight and that no further Starship flights will be attempted this year. 2:38 AM · Nov 25, 2024
Zitat SpaceX is reportedly targeting no earlier than January 11, 2025, for its highly anticipated 7th Starship Flight Test, according to new documents set to the FAA by NASA.
This mission, part of the ongoing development of SpaceX’s next-generation launch system, will feature close collaboration with NASA, which is contributing its expertise and resources to support the flight with the use of its Gulfstream V aircraft which will collect critical imaging data during the ships return to earth.
NASA's Gulfstream V aircraft, N95NA (callsign NASA5), will play a pivotal role in the mission by capturing high-resolution imagery of the Starship vehicle during its re-entry phase.
These observations are crucial for understanding the vehicle's performance under extreme conditions, particularly during peak heating. The imaging data will inform future spacecraft designs and contribute to making reusable space vehicles safer.
NASA has requested an expedited exemption from the Federal Aviation Administration (FAA) to conduct lightless operations for this mission.
According to NASA’s Johnson Space Center Air Operations Division, the aircraft will need to operate with all exterior and interior lights turned off during calibration flights and the mission itself. This is necessary to reduce interference with sensitive onboard imaging equipment.
The FAA exemption, if granted, will also serve as a template for international coordination, including with Australia’s Civil Aviation Safety Authority (CASA), where the aircraft will deploy to support the January launch.

Zitat Ellie in Space 🚀💫@esherifftv BREAKING: FAA issues license authorization for Starship Flight 7!
Today, the FAA issued a license modification authorizing SpaceX to launch multiple missions of the Starship/Super Heavy vehicle on the Flight 7 mission profile and vehicle configuration. The FAA determined SpaceX met all safety, environmental and other licensing requirements for the suborbital test flight. “The FAA continues to increase efficiencies in our licensing determination activities to meet the needs of the commercial space transportation industry,” said the Associate Administrator for Commercial Space Transportation Kelvin B. Coleman. “This license modification that we are issuing is well ahead of the Starship Flight 7 launch date and is another example of the FAA’s commitment to enable safe space transportation.” The Flight 7 mission profile involves launch of the combined Starship/Super Heavy vehicle from Boca Chica, Texas, a return to the launch site of the Super Heavy booster rocket for a catch attempt by the launch tower, and a water landing of the Starship vehicle in the Indian Ocean west of Australia. Please contact SpaceX for information about its planned launch date. The SpaceX Starship program operates under an FAA-issued Part 450 launch license.
ADDITIONAL LICENSE INFORMATION
Test Induced Damage Exceptions The Starship/Super Heavy Flight 7 license authorization includes Test Induced Damage Exceptions. SpaceX identified test objectives associated with certain flight events and system components of the Starship vehicle. The FAA evaluated each exception as part of flight safety and flight hazard analyses and confirmed that all public safety requirements have been met. The five approved test induced damage exceptions include: failure of the thermal shield during high-heating; failure of the flap system during high dynamic pressure; failure of the Raptor engine system during the landing Starship burn; failure of the Raptor engine system during in-space demonstration burn; and failure of Super Heavy systems during post-booster catch vehicle safing. If one of these scenarios occurs, a mishap investigation will not be required provided there was no serious injury or fatality, no damage to unrelated property and no debris outside designated hazard areas. Controlled / Uncontrolled Starship Vehicle Entry
The Starship/Super Heavy Flight 7 license authorization also includes the option for SpaceX to conduct a controlled or uncontrolled entry of the Starship vehicle. SpaceX must communicate a decision to conduct an uncontrolled entry to the FAA prior to launch. If SpaceX chooses an uncontrolled entry the loss of the Starship vehicle will be considered a planned event.
A mishap investigation will not be required for an uncontrolled entry provided there was no serious injury or fatality, no damage to unrelated property, and no debris outside designated hazard areas. 11:20 PM · Dec 17, 2024
