SpaceX’s next West Coast launches line up with flight-proven Falcon 9 rockets

Major SpaceX customer Iridium has set an official target date for its eighth and final Iridium NEXT launch, expected to fly on a flight-proven Falcon 9 Block 5 booster as early as December 30th.

With Iridium-8 now tentatively on SpaceX’s launch manifest, the company’s West Coast schedule appears to have stabilized with two more orbital missions before the end of 2018 – Spaceflight Industry’s SSO-A rideshare mission will aim for the second half of November while Iridium-8 will likely be the last global launch of 2018 if it sticks to its December 30 target.

Iridium CEO Matt Desch was happy to offer a few additional details after tweeting Iridium-8’s targeted launch date and confirmed that – despite original estimates to the contrary – the mission would launch on flight-proven Falcon 9 booster B1049.2. He also stated that the booster would attempt to land on SpaceX drone ship Just Read The Instructions after launch, passing up a Return-to-Launch-Site (RTLS) recovery at the freshly-coronated Landing Zone 4 (LZ-4) due to the significant weight and suboptimal trajectory of Iridium’s payload.

Barring unexpectedly heavy payloads, high-energy orbits, or new launch contracts, it’s probable that Iridium-8 will be the company’s last drone ship rocket recovery on the West Coast for at least a year, if not longer. The only unknown is whether SpaceX needs to or is able to launch during harbor seal pupping season, lasting from March to June – if that environmental concern can be sidestepped or altogether avoided, there may be no reason for Just Read The Instructions to remain in California when the drone ship could instead move to Florida and immediately facilitate faster launch cadence or support Falcon Heavy missions that could benefit from multiple booster landings at sea.

 

According to CEO Elon Musk and other executives, SpaceX is already building a third autonomous spaceport drone ship (ASDS) for the same reasons, to be named A Shortfall of Gravitas (ASOG) upon completion. Earlier this summer, Musk stated that the new vessel could be completed as early as summer of 2019, although he has since also stated that the first full BFR launches may take place on a floating platform somewhere off the coast of the US, increasing the probability of SpaceX delaying ASOG’s construction to allow for future use as both a launch and landing platform.

Triple booster reuse on the horizon

Returning to SpaceX’s Q4 2018 Vandenberg launch manifest, its launch of Spaceflight Industry’s SSO-A rideshare mission is expected to occur sometime next month and will likely be SpaceX’s second-to-last launch before the year is out. Notably, SpaceX executive Hans Koenigsmann recently suggested that SSO-A may end up playing host to the company’s first attempt to launch the same Falcon 9 booster three times. All previous Falcon 9 reuses have been the rockets’ second launches and typically saw SpaceX expend the booster in the ocean rather than recover it and attempt refurbishment for a third launch.

Falcon 9 Block 5, however, included a huge number of upgrades to the rocket’s overall stamina and reusability, theoretically raising the number of potential flights per booster from 10-100. Examined generally, moving from two to three flights per booster may seem inconsequential. The reality, however, is that the first true confirmation of the success or failure of SpaceX’s Falcon 9 Block 5 upgrade will be whether a Block 5 booster is able to safely complete three missions and do so with relative ease.

As SpaceX technicians and engineers gradually gain confidence with the new rocket iteration, debuted less than six months ago, the focus will eventually move from cautiously methodical design validation to rapid booster turnaround, eventually culminating in something approximating the 24-hour first stage reuse Musk challenged his company to achieve before 2019 is out. Ultimately, the third launch of a single Falcon 9 Block 5 booster will be the biggest step yet towards SpaceX’s ultimate goal of rapidly and affordably reusable orbital-class rockets.

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.
