SpaceX’s Falcon 9 Block 5 ready for first Return-To-Launch-Site booster landing

Published

Falcon 9 B1048.2 is vertical at SpaceX’s Vandenberg Space Launch Complex 4 (SLC-4) facilities ahead of the rocket’s second launch, targeted at 07:21 PM PDT, Oct. 7 (02:21 UTC, Oct. 8). A bit less than ten minutes after liftoff, B1048 will attempt a Return-To-Launch-Site (RTLS) landing just ~1400 feet from the launch pad.

Meanwhile, Mr. Steven is ready to depart Port of San Pedro in support of Falcon fairing recovery operations soon after liftoff, the vessel’s fifth attempted catch in ~12 months of active service with SpaceX.

A few hours after the vessel’s four arms and net were fully installed (the first time in more than six weeks), SpaceX technicians performed a series of last-minute tests with a Falcon fairing half placed on his net to verify that its mechanised rigging was working as intended, while also double-checking data connectivity between the fairing and its target (the net). Pre-launch checkouts largely completed, Mr. Steven now has to travel a short 200 miles to reach the region where SpaceX expects Falcon 9’s fairings to be recovered.

Of Falcons and fairings

It may feel quite different watching in real time, but SpaceX has made a huge amount of progress towards successful and routine fairing recoveries over the course of the last year and a half. Before the company became truly famous (and popular), more than two years (2013-2015) and a dozen distinct attempts were spent patiently learning how to recover Falcon 9 boosters, ranging from the first launch of Falcon 9 V1.1 (CASSIOPE, late 2013) to multiple instances where boosters exploded in spectacular fashions on drone ships Just Read The Instructions and Of Course I Still Love You after SpaceX began true landing attempts.

In fact, the first intact recovery didn’t even take place on a drone ship after years of extensive testing at sea – in December 2015, after separating from its Orbcomm-2 satellite constellation payload, Falcon 9 B1019 became the first booster recovered by SpaceX in one piece, landing almost flawlessly at the company’s just-finished Cape Canaveral landing zone, known as LZ-1. Several months later, SpaceX successfully recovered its first Falcon 9 at sea, landing a booster on OCISLY shortly after launching the CRS-8 Cargo Dragon mission, although several more failures or near-failures followed as recovery technicians and engineers worked through a diverse and unpredictable series of challenges as they arose.

Rocket recovery: it’s not easy

Even in 2018, SpaceX unintentionally expended Falcon Heavy’s center core, demonstrating that even three dozen successful Falcon 9 and Heavy booster recoveries are not necessarily enough to shine light on or predict all possible modes of failure. Around 7:21 PM (PDT) today, barring a scrubbed launch attempt, the already-flown Falcon 9 booster B1048 – refurbished from landing to launch in just ~74 days – will likely launch and land once more, and most of the world wont even blink and eye. In the eyes of those that don’t or haven’t followed SpaceX obsessively, rocket booster recovery and reuse is to some extent already perceived as routine, logical, and inevitable less than three years after the technology’s first true Kitty Hawk moment.

 

The point of this brief SpaceX history lesson is to emphasize that fairing recovery is an extremely young technology, even for SpaceX. Before Mr. Steven swooped into existence, SpaceX had begun attempting to softly land payload fairings in the ocean around the start of 2017, and Mr. Steven famously returned to Port of San Pedro with an intact (but unreusable) fairing half in March 2018 after successfully launching Earth-imaging satellite PAZ. Comparing historical apples to present-day oranges, it may be safe to assume that fairing recovery’s Orbcomm-2 moment – Mr. Steven’s first successful catch – is already on the horizon.

In the meantime, it never hurts to remind oneself that – vicarious frustrations aside – observers are likely watching history unfold in real-time once again. SpaceX’s SAOCOM-1A launch webcast will begin around 7PM PDT – 15 or 20 minutes prior to launch – and can be found at the link below.

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.
