Starship Flight Test 2

Starship Flight Test 2 (unofficially IFT-2, or Integrated Flight Test 2), was the second test flight of Super Heavy and Starship to near orbit that took place on November 18 2023. Booster 9 and Ship 25 were chosen to fly in this test flight. The full stack lifted off with 33 engines running and survived hot-staging. But during the boostback burn multiple engines shutdown and Booster 9 was terminated at around 90km over the Gulf of Mexico. Meanwhile, Ship 25 became the first Starship to reach space, nearly completing its 6-engine burn. To simulate how much propellant Starship would have had, if it had been carrying a payload, Liquid Oxygen was vented out of the tank. This ultimately led to an fire and the AFTS was triggered at an altitude of 148km and a speed of over 24000 km/h. Unlike OFT-1, no severe damage was apparent on the orbital launch mount after the launch.

## Name

The community often uses the name OFT-2 (Orbital Flight Test), knowing that Starship will not reach full orbit on its test flight. This is the reason that SpaceX calls it IFT-2 (Intergrated Flight Test) to difference it from atmospheric flights.

## Status

IFT-2 took place 18 November 2023.

On 04 August 2023, Elon Musk shared his expectations of this flight as B9 conducted a spin prime test for verification: "Preparing for next Starship flight! This time, I think we have ~50% probability of reaching orbital velocity, however even getting to stage separation would be a win".

On 08 September 2023, the FAA announced that the mishap investigation following IFT-1 was closed. As a result, SpaceX needs/needed to work 63 corrective actions such as launch infrastructure and vehicle upgrades.

On 31 October 2023, the FAA has finished its safety review for the second flight of Starship.

On 3 November 2023, SpaceX said on X: "The second flight test of a fully integrated Starship could launch as soon as mid-November, pending regulatory approval"

## Post-Launch announcements

### 21 December 2023

Video of Kathy Lueder's speech at the SpaceX Post Launch Conference has been released. With that we've been able to confirm and deny some facts from the news article:

* SpaceX is indeed planning to add another Pad at Starbase.
	+ "Looking at adding another pad, because with the cadence we'd like to have getting that second pad ready was gonna be another goal we have for this year"
* Kathy has not said that engine testing will be happening at Massey's, only that they're moving more of their testing there.
	+ "Using our Massey's test site [...] what it allows us to do is keep our test operations at the Massey's test site and away from the beach. [...] We're moving more of our testing over there"
* Booster 9 RUD was, according to Kathy, a deliberate termination. RUD of Ship 25 was not mentioned.
	+ "After the second Starship flight we separated and then terminated the first stage"
* SpaceX is submitting applications for Flight 3 & 4.
	+ "Submitting for our flight 3 and flight 4 applications"

### 13 December 2023

Kathy Lueders update in Brownsville:

* SpaceX is in the process of submitting flight approvals and amendments for flights #3 and #4
* They will continue to monitor sound levels especially during low cloud cover and higher winds
* Both Starship and Booster RUD likely due to AFTS and they are working on the mishap investigation to conclude why
* Hoping to start catching boosters sometime in 2024
* Confirmed plans of second tower at Starbase and moving engine testing to Massey
* Planning for multiple flights in 2024
* Says they are aiming for 1Q 2024 for IFT-3, says unlikely to achieve December despite Elon aspirations

### 07 December 2023

SpaceX released the recap video and confirmed that Ship 28 and Booster 10 (Starship 10/28) will take flight on IFT-3.

### 21 November 2023

Official conclusion by SpaceX:

Starship returned to integrated flight testing with its second launch from Starbase in Texas. 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.

On November 18, 2023, Starship successfully lifted off at 7:02 a.m. CT from Starbase in Texas and achieved a number of major milestones:

* All 33 Raptor engines on the Super Heavy Booster started up successfully and, for the first time, completed a full-duration burn during ascent.

* Starship executed a successful hot-stage separation, powering down all but three of Super Heavy’s Raptor engines and successfully igniting the six second stage Raptor engines before separating the vehicles. This was the first time this technique has been done successfully with a vehicle of this size.

* Following separation, the Super Heavy booster successfully completed its flip maneuver and initiated the boostback burn before it experienced a rapid unscheduled disassembly. The vehicle breakup occurred more than three and a half minutes into the flight at an altitude of ~90 km over the Gulf of Mexico.

* Starship's six second stage Raptor engines all started successfully and powered the vehicle to an altitude of ~150 km and a velocity of ~24,000 km/h, becoming the first Starship to reach outer space and nearly completing its full-duration burn.

* The flight test’s conclusion came when telemetry was lost near the end of second stage burn prior to engine cutoff after more than eight minutes of flight. The team verified a safe command destruct was appropriately triggered based on available vehicle performance data.

* The water-cooled flame deflector and other pad upgrades performed as expected, requiring minimal post-launch work to be ready for upcoming vehicle tests and the next integrated flight test.

With a test like this, success comes from what we learn, and this flight test will help us improve Starship’s reliability as SpaceX seeks to make life multiplanetary. Data review is ongoing as we look for improvements to make for the next flight. The team at Starbase is already working final preparations on the vehicles slated for use in Starship’s third flight test, with Ship and Booster static fires coming up next.

Thank you to our customers, Cameron County, spaceflight fans, and the wider community for the continued support and encouragement. And congratulations to the entire SpaceX team on an exciting second flight test of Starship!

### October 2023

#### 31 October 2023 - FAA finishes safety review

On 31 October 2023, the FAA has finished its safety review for the second flight of Starship. This is one of the lasts steps that is needed for a approval of the FAA for IFT-2. Currently the FWS (Fish and Wildlife services) have not finished their review of the water deluge system. This is not expected to take long before its review is finished. If the FWS finds no negative impact for the water deluge system, the FAA will be able to give SpaceX their license for flight 2 of Starship.

##### FAA Statement:

The FAA completed the safety review portion of the SpaceX Starship-Super Heavy license evaluation on Oct. 31.

Background

A safety review is focused on issues that affect public health and safety of property. It consists of evaluating the applicant's safety organization, system safety processes, flight safety analysis, and quantitative risk criteria for launch, reentry, and vehicle disposal. The FAA is continuing to work on the environmental review. As part of tis environmental review, the FAA is consulting with the U.S. Fish and Wildlife service (USFWS) on an updated Biological Assessment under the Endangered Species Act. The FAA and the USFWS must complete this consultation before the environmental review portion of the license evaluation is completed.

#### 26 October 2023 - FWS Statement

In a recent statement from the Fish and Wildlife services, they said that they are considering the effects of the water deluge system that has been recently installed under the launch pad at Starbase.

##### Statement from the FWS:

* On Oct. 19, the U.S. Fish and Wildlife Service reinitiated the Endangered Species Act consultation with the FAA. We have up to 135 days to issue an amended biological opinion but do not expect to take the full amount of time.
* Under Section 7 of the Endangered Species Act, reinitation of formal consultation is required when a project and its impacts change significantly, the amount of take issued previously is exceeded, we have new information on listed species not previously considered, or a new species is listed.
* For SpaceX reinitiation with FAA we are considering the operation of a deluge system at the launch pad.

#### 25 October 2023 - NOTMAR Update

Placeholder NOTMARs were issued for a potential launch going into effect on November 6th and onwards.

#### 20 October 2023 - SpaceX announcement

"Starship team preparing for additional preflight tests in advance of a full launch rehearsal while continuing to work with the FAA on the Flight 2 license."

#### 18 October 2023 - NOTMAR Update

In the recent NOTMAR update, there has been a new launch date given. SpaceX now targets the 1st of November for IFT-2 (Note: It is likely to get pushed as SpaceX still needs a launch license from the FAA).

On November 1, 2023, between 5:25 a.m. and 11:15 a.m., rocket launching operations are scheduled to take place near Boca Chica Beach, Texas. Back-up launch dates and times include each day following November 1, 2023, between 5:25 a.m. and 11:15 a.m., until conditions permit the launch.

#### 18 October 2023 - FAA and FSW

In a statement on Tuesday, a FWS spokesperson said their agency received a final biological assessment from the FAA Oct. 5 and FWS has up to 30 days to review it. This came after the FAA sent FWS a letter in August, which requested "reinitiation of Endangered Species Act consultation." Following the 30-day review of the final biological assessment from the FAA, the FWS has "135 days to issue an amended biological opinion."

#### 17 October 2023 - Washington Post

"As the consultation with FAA and US Fish and Wildlife over the Starship mishap will likely push into November, further delaying a second launch attempt, SpaceX is calling on Congress to push FAA to issue launch licenses faster"

#### 16 October 2023 - SpaceX

Starship fully stacked while team prepares for a launch rehearsal. We continue to work with the FAA on a launch license

### September 2023

#### 30 September 2023 - SpaceX and Elon Musk

SpaceX: "Starship stacked at Starbase ahead of flight, team continues to work with the FAA on a launch license"

Elon Musk: "Starship is ready for flight 2!"

#### 18 September 2023 - FAA and FWS

FAA has submitted a draft update of the Biological Assessment to the US Fish and Wildlife Dept sometime this august:

* The FWS is considering the operation of a water deluge system in Starbase and its environmental effects.
* The FWS has up to 135 days to submit the final biological opinion to the FAA (Started in August).

#### 15 September 2023 - FAA Newsletter

In a newsletter, the FAA anounced that they are conducting a Written Reevaluation to the PEA due to changes of the launch infrastructure as part of the license application determination process:

"SpaceX conducted a test flight of the Starship/Super Heavy at Boca Chica, TX on April 20, 2023. As a result of that launch, SpaceX completed a mishap investigation with FAA oversight; this investigation analyzed the launch, mishap events, and corrective actions. Before it is authorized to conduct a second Starship/Super Heavy launch, SpaceX must obtain a modified license from the FAA that addresses all safety, environmental, and other regulatory requirements. As part of that license application determination process, the FAA will review new environmental information, including changes related to the launch pad, as well as other proposed vehicle and flight modifications. The FAA will complete a Written Reevaluation (WR) to the 2022 Programmatic Environmental Assessment (PEA) evaluating the new environmental information, including Endangered Species Act consultation with the U.S. Fish and Wildlife Service. If the FAA determines through the WR process that the contents of the PEA do not remain valid in light of the changes proposed for Flight 2, additional environmental review will be required. Accordingly, the FAA has not authorized SpaceX's proposed Flight 2. The FAA will provide updates with notification of any license determination or results of additional environmental review."

Although it can be expected that the WR finds that the PEA remains vaild, the very cautious wording by the FAA is likely aimed at critics of the FAA.

#### 13 September 2023

Reuters / FAA / Starship Gazer: No FAA Starship launch license until October at the soonest according to a new statement by acting FAA Administrator Polly Trottenberg. And SpaceX also still needs a separate environmental approval from the U.S. Fish and Wildlife Service.

#### 11 September 2023

Jeff Foust: SpaceX senior vice president of commercial business Tom Ochinero says that the company is "real close" to next launch and that they are working closely with the regulators" at this point.

#### 10 September 2023 - Elon Musk

Elon Musk posted two pictures containing the 63 corrective actions mentioned by the FAA on 08 September 2023, with most of them being completed. According to Elon Musk, the six items that remain open are not necessary for the upcoming flight: "Worth noting that 6 of the 63 items refer to later flights."

SpaceX's 63 items for upgrading Starship and Pad after Starship 7/24 for FAA mishap investigationSpaceX's 63 items for upgrading Starship and Pad after Starship 7/24 for FAA mishap investigation
#### 08 September 2023 - SpaceX

SpaceX issued an update on upgrades ahead of Starhsip's second flight test (for the updates on OFT-1, see OFT-1):

The main cause for OFT-1 mishap were fires in the engine bay which severed connection with the primary flight computer, leading to a loss of communication to the engines and thus to the loss of vehicle control. "SpaceX has since implemented **leak mitigations** and **improved testing** on both engine and booster hardware. As an additional corrective action, SpaceX has significantly expanded Super Heavy’s pre-existing **fire suppression system** in order to mitigate against future engine bay fires." Due to the delay in the autonomous flight safety system (AFSS), "SpaceX has enhanced and **requalified the AFSS** to improve system reliability".

"SpaceX is also implementing a full suite of system performance upgrades unrelated to any issues observed during the first flight test. For example, SpaceX has built and tested a **hot-stage separation system,** in which Starship’s second stage engines will ignite to push the ship away from the booster. Additionally, SpaceX has engineered a new **electronic Thrust Vector Control** (TVC) system for Super Heavy Raptor engines. Using fully electric motors, the new system has fewer potential points of failure and is significantly more energy efficient than traditional hydraulic systems."

"SpaceX also made significant upgrades to the **orbital launch mount** and pad system in order to prevent a recurrence of the pad foundation failure observed during the first flight test. These upgrades include significant reinforcements to the pad foundation and the addition of a **flame deflector,** which SpaceX has successfully tested multiple times."

Elon Musk also mentioned that the launch tower chopsticks were upgraded too: "Thousands of upgrades to Starship & launchpad/Mechazilla"

#### 08 September 2023 - FAA

On 08 September 2023, the FAA announced that they have closed the SpaceX Starship Mishap Investigation.  Aside from giving some details on the OFT-1 mishap causes (see OFT-1), this notice is an important indicator of progress towards the next launch.

According to the final mishap investigation report, SpaceX has to implement **63 corrective actions:** "These included actions to address redesigns of vehicle hardware to prevent leaks and fires, redesign of the launch pad to increase its robustness, incorporation of additional reviews in the design process, additional analysis and testing of safety critical systems and components including the Autonomous Flight Safety System (AFSS), and the application of additional change control practices." It is obvious, that SpaceX was already working on some of this actions during the months after OFT-1, as major upgrade work on the launch infrastructure as well as on the vehicles was observed.

The FAA also highlighted the steps necessary on the path to a next integrated flight test (see IFT-2). SpaceX is required to apply for a modification of the old license for which they have to demonstrate that they have implemented the above mentioned corrective actions. The FAA then has to approve the modifications.

#### 06 September 2023

Eric Berger / FAA: According to Eric Berger, the FAA says that the Starship mishap investigation remains open.

NAVCEN: Marine notices for both the Gulf and Hawaii have been pulled as of 9/6 and no future date is currently scheduled

This time, I think we have ~50% probability of reaching orbital velocity, however even getting to stage separation would be a win". And ship 25 has had a spin prime and static fire test.
