SpaceX has pulled off an incredible feat, successfully recovering all three of Falcon Heavy’s Block 5 boosters shortly after the rocket’s commercial launch debut. Followed about two minutes later by the center core’s bullseye drone ship landing, both side boosters once again performed a near-simultaneous recovery at SpaceX’s Cape Canaveral Landing Zones.

With this flawless triple recovery in hand, SpaceX now has plans to reuse both side boosters as early as June 2019, while the center core will likely support critical reusability analysis and may also launch again in the near future. Above all else, Falcon Heavy Flight 2 has demonstrated that SpaceX’s super heavy lift rocket is truly ready to offer routine commercial services for customers – both public and private – around the world. With a combination of reusability, affordability, and performance unlikely to be matched for a minimum of 2+ years, SpaceX and its Falcon Heavy rocket have the opportunity to create an entirely new market in the coming years.

Completed less than 35 minutes after launch, this mission included a wealth of major events and firsts, including the first launch of Falcon Heavy Block 5, the first successful triple booster recovery, and one of the highest orbital apogees yet seen during a SpaceX mission – >90,000 km (55,500 mi) above Earth.

The huge Arabsat 6A satellite – weighing around 6450 kg (14,200 lb) is not quite the heaviest individual spacecraft SpaceX has launched, but it is by far the highest energy orbit SpaceX has reached with a spacecraft anywhere close to its size. Known as a supersynchronous (perhaps ultrasynchronous?) transfer orbit, the extremely high apogee – almost three times higher than the nominal circular orbit Arabsat 6A is destined for – will help the satellite reach that orbit far sooner than it otherwise would. The sooner a spacecraft can begin nominal operations, the sooner it can begin making money for its owner/operator.

Around seven and a half minutes after launch, Falcon Heavy side boosters B1052 and B1053 nailed a flawless simultaneous landing at SpaceX’s Cape Canaveral-based Landing Zones (LZ-1 & LZ-2). Less than three minutes later, center core B1055 hit the bullseye on drone ship Of Course I Still Love You, wrapping up the first successful landing of the critical Falcon Heavy booster.

With three once-flown Block 5 boosters now in hand, SpaceX will attempt to turn around both side boosters – basically just Falcon 9 first stages with nose cones – for Falcon Heavy’s third launch, potentially as early as June 2019. Meanwhile, the center core will complete another 1000 km journey, this time back to the Florida coast before likely shipping to Hawthorne, California or a local hangar for analysis. Falcon Heavy’s center core, as is fairly visible, is dramatically different from the Falcon 9 boosters SpaceX is used to reusing, including a range of connection hardware that is absolutely flight-critical and protrudes rather aggressively into the rocket’s often-violent airstream.

In other words, Falcon Heavy center cores could get far more toasty than Falcon 9 or even their side booster companions, potentially damaging hardware that simply has to be perfect for Heavy launches to succeed and do so reliably. As such, SpaceX will likely be expecting to learn a fair bit of new information and gather critical data in the hopes of eventually optimizing Falcon Heavy center core refurbishment and reuse to Falcon 9’s current level of finesse.

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.
