SpaceX’s Falcon 9 fairing catcher Mr Steven preps for October recovery attempt

Published

Following a 45-day armless hiatus, SpaceX fairing recovery vessel Mr Steven’s four net-supporting arms have reappeared at its Berth 240 home, potentially giving SpaceX technicians enough time to install them for a fifth attempt at snagging a Falcon 9 fairing half.

That fifth Falcon fairing recovery attempt could occur as early as ~8 pm PDT, October 6th, roughly half an hour after SpaceX is scheduled to launch a flight-proven Falcon 9 Block 5 rocket with SAOCOM-1A, a 3000 kg (6600 lb) Earth observation satellite built for Argentinian space agency CONAE.

SpaceX’s most recent Vandenberg launch and fairing recovery attempt occurred on July 25th and successfully placed the sixth group of 10 Iridium NEXT communications satellites into orbit, after which Falcon 9 B1048 managed a safe landing aboard drone ship Just Read The Instructions (JRTI). JRTI returned to Port of San Pedro on July 28th and Block 5 booster B1048 has spent its subsequent ~70 days on dry land being refurbished for SAOCOM-1A, perhaps providing a taste of things to come for SpaceX launch operations.

Mr Steven, on the other hand, has been relegated to its Port of Los Angeles berth for the last month and a half, following the removal of his four arms, eight complementary booms, and large net. Presumably scheduled for upgrades after additional real-world testing, those arms and booms disappeared from Berth 240 around August 22nd and were spotted back beside Mr Steven on October 1st. Curiously, at least one arm had legible shipping manifest stickers applied, suggesting that the central arm structure, an entire arm, or even all four arms were shipped somewhere by air in interim.

 

Thanks to a new structural design allowing each arm to be easily disassembled into half a dozen major subsections, air shipment is likely a breeze compared to nearly all other large pieces of SpaceX hardware. Where or why they were shipped is unclear, although the expense of transporting ungainly and heavy items by air may indicate that schedule margins were too tight and the distance too far for road transport.

Mr Steven’s eight shock-absorbing arm booms have yet to be spotted at or around Berth 240, but chances are looking good for the vessel to have his arms reattached in time to attempt a fairing catch shortly after SAOCOM-1A. Judging from photos of the recently returned arms, any obvious before and after differences are few and far between, meaning that any visible upgrades to the recovery mechanism will instead be found with the booms.

Longer arm booms could perhaps increase the working area of Mr Steven’s arms at the cost of dropping his net closer to the deck and late-July testing that involved placing an actual fairing on the net appeared to indicate that margin is available to lower his net further. We’ll find out soon as the booms arrive and SpaceX technicians (hopefully) begin reinstalling the vessel’s arms and net over the next several days.

SpaceX and Elon Musk explain potential reasons for Starship loss

SpaceX and its CEO Elon Musk are starting to shed some light on the potential reasoning for the loss of Starship yesterday, which was lost after a successful launch and catch of the lower-stage booster.

Starship was lost during its ascension, and debris rained down over the Caribbean less than an hour after SpaceX lost all communication with the spacecraft.

A few hours after the launch was over, SpaceX started to shed some light after looking at preliminary data that the rocket left behind.

The company said that a fire developed in the aft section of Starship:

“Following stage separation, the Starship upper stage successfully lit all six Raptor engines and performed its ascent burn to space. Prior to the burn’s completion, telemetry was lost with the vehicle after approximately eight and a half minutes of flight. Initial data indicates a fire developed in the aft section of the ship, leading to a rapid unscheduled disassembly with debris falling into the Atlantic Ocean within the predefined hazard areas.”

Additionally, Musk said that there was some sort of oxygen or fuel leak in the cavity above the ship engine firewall.

The leak was evidently large enough to build more pressure than the vent was able to handle:

Some also seemed to recognize evidence of fires throughout the flight of Starship, which is obviously an anomaly:

There will be more information regarding the loss of Starship in the coming days and weeks, but Musk already believes that a bit of fire suppression and more volume in the cavity above the ship engine firewall could fix the issue.

“Nothing so far suggests pushing next launch past next month,” he said, so Flight 8 could happen sometime in February.

SpaceX completes second catch of lower stage, but loses Starship

SpaceX completed its seventh launch of Starship on Thursday, accomplishing a clean liftoff and catch of the first-stage booster. However, the upper stage was lost after its ascent.

The launch took place just a few minutes after 5 p.m. on the East Coast, as the first attempts at getting Starship in the air for the seventh time were delayed by weather both last week and this week.

Conditions were favorable on Thursday as SpaceX looked to follow up a successful campaign by Blue Origin, Jeff Bezos’s company, earlier today.

SpaceX went into the seventh Starship launch with plans for a catch attempt of the first-stage booster, something it attempted and completed during the fifth test launch last year. It decided to skip a catch attempt with the sixth test flight as conditions were not aligned.

For now, SpaceX is extremely selective as to when it attempts catches.

However, it was successful during this attempt, its second completed catch:

This flight differed from previous launches as SpaceX rolled out several improvements to the rocket and the processes as it featured plans to do a Starlink deployment simulation and had various adjustments to flap placement and avionics.

These plans were disrupted by the fact that SpaceX lost all communications with Starship about ten minutes into the flight, which the aerospace company confirmed was a result of losing the spacecraft sometime during its ascent.

Although the catch was successful, the loss of the actual rocket seemed to be a huge damper on the entire event. SpaceX confirmed several minutes after the loss of communications that the rocket was destroyed and was lost.

It was its first failure since the second Starship launch in November 2023. SpaceX had no answers for why the rocket was destroyed and lost.

We will keep you updated in the coming days.

SpaceX confirms next Starship launch target – Here’s when it will take off

SpaceX has confirmed a new target date for the seventh Starship test launch after weather in Texas delayed the first scheduled date for “three or four days.”

The company is now targeting the launch for Monday, January 13, at 4 p.m. CST or 5 p.m. EST. The launch date is not set in stone as any variety of delays could impact this, but SpaceX hopes to finally take off after a delay that pushed it back from January 10.

What’s new with this Starship launch

With this being the seventh test launch of Starship, there are several things that the company will change and hope to accomplish. All of these launches are done in preparation for eventually taking flight to Mars, something that will happen next year, according to CEO Elon Musk.

First, SpaceX is rolling out a next-generation ship with “significant upgrades.” Forward flaps have been made smaller and are repositioned away from the heat shield, which will “reduce their exposure to reentry heating.”

SpaceX eyes 25 annual Starship launches starting next year

There is also a 25 percent increase in propellant volume, a new fuel feedline system for the Raptor vacuum engines, and a better-than-ever propulsion avionics module that will control the valves and reading sensors.

Avionics, as a whole, underwent a redesign and now have more capability and redundancy for missions as they become more complex.

Starlink test

SpaceX is also planning to deploy 10 Starlink simulators that are similar in size and weight to the next-generation Starlink satellites:

“While in space, Starship will deploy 10 Starlink simulators, similar in size and weight to next-generation Starlink satellites as the first exercise of a satellite deploy mission. The Starlink simulators will be on the same suborbital trajectory as Starship, with splashdown targeted in the Indian Ocean. A relight of a single Raptor engine while in space is also planned.”

Ship return and catch

There will be several experiments that have to do with returning Starship and various catch scenarios and sequences. One of which will see “a significant number of tiles be removed to stress-test vulnerable areas across the vehicle.”

The ship’s reentry profile was also intentionally designed to test the structural limits of the flaps while at the point of maximum dynamic pressure during reentry.

Currently, SpaceX did not detail whether it would attempt another catch during this test launch. These are usually game-time decisions.
