SpaceX plans Falcon 9 satellite launch from Pad 39A prior to Crew Dragon, Falcon Heavy

(SpaceX)

SpaceX plans to launch one final commercial Falcon 9 mission from Pad 39A before much of the historic facility’s availability is taken over Crew Dragon and Falcon Heavy launch needs, perhaps as soon as December 2018.

The reason for the decision to launch a routine Falcon 9 mission from 39A – while Launch Complex-40 (LC-40) is (presumably) perfectly available – is unknown, but it can likely be pinned down to launch schedule assurance and pad shakedowns ahead of the flight debut of Crew Dragon, NET January 2019.

Dragons’ rule

Ultimately, the decision to move the launch of commercial communications satellite Es’Hail-2 to Pad 39A likely boils down to a desire to preserve the delay-sensitive CRS-16 Cargo Dragon launch (NET November 27) while also acting as a sort of ad-hoc shakedown for the pad. 39A has undergone a large number of Crew Dragon-related modifications – some visible but most not – and will have been dormant (at least launch-wise) since Falcon 9 Block 5’s debut six months prior.

Whether or not it’s truly needed, another Falcon 9 launch from the pad will presumably allow SpaceX to work out any new kinks in 39A’s updated ground support infrastructure and perhaps refamiliarize the company’s East Coast launch crew after half a year focused on LC-40 operations. Es’Hail-2 is a ~3000 kg (~6600 lb) geostationary communications satellite to be operated by Qatari company Es’hailSat once it arrives at its final operational orbit.

Despite a recent presentation from SpaceX VP of Reliability Hans Koenigsmann stating that Falcon 9 is capable of returning to launch site (RTLS; i.e. a Landing Zone recovery) while still placing 3500 kg into a geostationary transfer orbit (GTO), SpaceX has filed this launch as an ASDS (autonomous spaceport drone ship) recovery, meaning that it will land aboard Of Course I Still Love You (OCISLY) shortly after launch. Delayed from August 2018, SpaceX may be trying to partially make up for that slip by placing Es’Hail-2 sat in as high of a transfer orbit as possible, potentially cutting weeks or even months off of the time required for the satellite to climb uphill to its operational orbit.

An East Coast lull

Unusual for SpaceX in an otherwise meteoric year filled with numerous major ‘firsts’ and the company’s most productive launch cadence yet, there will be a two-month lull in launches from the East Coast between Telstar 18V (September 10) and Es’Hail-2 (NET November 14), interrupted only by the spectacular October 7 launch of SAOCOM 1A in California. Barring any additional issues, SpaceX will likely crest its 2017 launch record (18 missions) by 3 or 4 missions, not quite the 25-30 launches much of the company’s leadership was probably hoping for, but still an extremely impressive number.

Despite the fact that launch delays are never pleasant (much like if Christmas were pushed back weeks or months to wait for sleigh and present availability), the willingness to significantly delay launches or fall short of targets (assuming payload availability has not been the long pole) is actually a very good thing. Within reason, inconvenient delays tend to serve as evidence that SpaceX is not succumbing to quite the same level of “Go fever” and manager/engineer/technician disconnection that has arguably been responsible for a huge number of launch failures, particularly for NASA’s Space Shuttle.

 

Best described as the point at which non-technical pressures to launch (cost-saving, internal and external politics, general face-saving) far outweigh the voices of the engineers and technicians responsible for reliably designing, building, and launching rockets, “Go fever” is demonstrably one of the worst things that can occur in spaceflight-oriented organizations, where the consequences of even the tiniest failures can often be amplified into total mission and vehicle failures and even the death of employees or astronauts. It may be unpleasant as an unaffiliated follower or fan and is likely far less pleasant still as an employee or manager, but it is undeniably preferable to succeed after weeks or months of delays than to fail catastrophically while staying on schedule.

Speaking of schedules, Es’Hail-2 (39A) is NET Nov. 14, followed by SSO-A (SLC-4E, Vandenberg) NET Nov. 19 and SpaceX’s 16th operational ISS resupply mission – CRS-16 – on Nov. 27th from Pad 40. Heading into the last month of 2018, SpaceX will launch the first of a fleet of new GPS III satellites for the USAF (NET Dec. 15) and finish off the year with a Vandenberg buzzer-beater, the eighth and final Iridium NEXT launch, NET Dec. 30.

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.
