SpaceX bags 60th successful Falcon 9 launch eight years after rocket’s debut

Published

7 years ago

Following the successful separation of the ~7 metric ton satellite Telstar 18V after a nominal orbit insertion, SpaceX’s venerable Falcon 9 rocket can now lay claim to a full 60 successful orbital missions completed over the course of its relatively brief eight-year career as a commercial launch vehicle.

Telstar 18V – the second heaviest commercial satellite ever launched into orbit – is now free to make its way into a final geostationary orbit ~35,800 km (~22,250 mi) above Earth’s surface, where it will serve the Eastern Hemisphere with a variety of communications services, ranging from TV to internet.

After Falcon 9’s upper stage separated from the first stage and pushed onwards to a low Earth parking orbit, Falcon 9 Block 5 booster B1049 flipped around using an array of powerful cold-gas nitrogen thrusters and arced towards a now-routine drone ship landing roughly 700 kilometers off the Florida coast, breaking the satellite communications link as per usual before appearing aboard Of Course I Still Love You.

With Hurricane Florence nipping at the drone ship and its entourage’s heels, SpaceX will likely try to quickly usher the Falcon 9 booster back to Port Canaveral, where it will be offloaded, brought horizontal, and transported to a local facility for refurbishment ahead of its next flight, hopefully the first of many to come. Falcon 9 Block 5 has been designed – nominally – for rapid and extensive reusability, perhaps up to 100 flights per booster with routine maintenance (10 flights with minimal refurbishment) and turnaround as rapid as 24 hours for the same core. While it appears that there may be a significant amount of work left before those aspirational figures can be made real, Block 5 is clearly a major step forward for the Falcon 9 family and includes – aside from reusability – upgrades that will enable the rocket to launch NASA astronauts aboard Crew Dragon with extreme reliability.

 

Compared alongside almost all other modern rockets, Falcon 9 is exceptional for the sheer speed with which it has burst onto the commercial launch scene, with Boeing’s nearly-retired Delta II family of rockets the only vehicle to hold a candle to Falcon 9 in terms of competitive advantage. Delta II, which debuted in 1989, managed a thoroughly impressive seven launches in its first year of operations and a full 55 launches (53 successes, 1 partial failure, 1 total failure).

With one partial in-flight failure (a secondary payload loss during CRS-1), one total in-flight failure (CRS-7), and one on-pad failure (Amos-6), Falcon 9 is truly comparable with Delta II, although Boeing’s expendable launch vehicle has, of course, remained permanently expendable, and relied almost unilaterally upon the US government for all but a small handful of its first several dozen launches. SpaceX’s Telstar 18V success is just one of many examples of this difference of interest in commercial competition, and a full 12 of the 16 missions SpaceX has now launched in 2018 flew commercial satellites and were awarded to the launch company on a competitive basis.

Up next for SpaceX is Argentinian Earth observation satellite SAOCOM-1A, scheduled to launch from California’s Vandenberg Air Force Base atop a flight-proven Falcon 9 Block 5 booster no earlier than October 7th.

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.
