SpaceX’s most flown Falcon 9 booster met an abrupt end this week when it toppled over aboard a drone ship amid rough seas on its journey back to Port Canaveral. The booster, dubbed B1058, had just launched its 19th mission – a record for rocket reuse – but was unable to stick the landing due to challenging weather conditions.
Most-Flown Booster Succumbs to Extreme Weather
On December 23rd, B1058 helped propel a communications satellite for Intelsat into orbit from Cape Canaveral Space Force Station. After separating from the upper stage, the soot-covered booster guided itself back through the atmosphere and approached the deck of the drone ship “A Shortfall of Gravitas” stationed in the Atlantic Ocean.
However, an extreme storm with 20-foot seas and 50-knot winds battered the vessel, causing the 15-story booster to slowly topple over. It eventually broke apart entirely as crews could only watch helplessly. SpaceX was unable to secure or retrieve any parts of the booster as the weather prevented further operations at sea.
| Flight Number | Launch Date | Payload | Outcome |
|---|---|---|---|
| 1 | May 2020 | Crew Dragon Demo-2 | Success |
| 2 | June 2020 | Starlink | Success |
| … | … | … | … |
| 19 | Dec 2023 | Intelsat G-33/G-34 | Toppled at sea |
“We tried to save Falcon after the Intelsat launch, but the sea states were too rough,” said SpaceX CEO Elon Musk. “We took it as far as reasonably possible.”
B1058 Blighted by a Bittersweet Ending
B1058’s journey from routine booster to fleet leader and company mascot ended unceremoniously after defying the odds on so many occasions. Its record-setting 19 flights were more than twice the previous mark of 8, showing the immense reusability of SpaceX’s Falcon 9 rockets.
The booster’s milestones include launching the first crude Crew Dragon, bobbing conspicuously during NASA’s prep for human spaceflight, and lofting satellites that now layer SpaceX’s Starlink network. It even became an unofficial mascot for the company’s Florida operations.
So for the storied vehicle to be lost mere miles from its Cape Canaveral home was nothing short of heartbreaking for teams that nursed it back to flightworthy health after every return.
“It’s almost like losing a friend or a family member,” said manufacturing supervisor Steven Pavlovich. “I feel sad about it.”
Investigation Underway Into Exact Sequence of Events
SpaceX engineers are still piecing together what exactly transpired in B1058’s final minutes. The company typically tries to secure falling boosters using remote-controlled fast boats with large metal arms to grapple the vehicles.
But the extreme conditions likely prevented crews from approaching as the booster slowly tipped over, eventually crashing onto the deck with enough force to break open tanks and structures. Ignited fuels may have created explosions that further damaged the vehicle.
“It is not impossible that residual propellants reignited,” said CEO Elon Musk, though the company has not confirmed that as having occurred.
Workers did manage to safely return from the damaged drone ship on December 24th after the failed recovery attempt. SpaceX will investigate whether procedures or technology improvements could have saved the booster under the same circumstances.
Bittersweet End, But Legacy of Rocket Reuse Secure
The demise of rocket B1058 is certainly bittersweet for SpaceX engineers who became attached to the vehicle that continuously defied expectations. But its 19 successful launches cemented the case for reusing rockets to drastically lower launch costs.
The booster embodied CEO Elon Musk’s vision to establish humanity as multiplanetary while generating revenue through affordable launch services. B1058’s reliability and resilience advanced that dream closer to reality.
In fact, the milestone of 10 flights for a single orbital rocket booster was once thought impossible. B1058 proved the critics wrong by doubling that mark with room to spare before meeting its untimely end after getting the job done once again.
Its legacy will live on through a fleet of Falcon boosters built to match its success. And B1058’s record may one day fall to another hardy vehicle that manages to best the once unachievable flight count – though for now, none loom as daring and dependable as the mascot many at SpaceX called their favorite.
What’s Next For SpaceX Launch Campaigns
While the loss of B1058 was certainly emotional, SpaceX maintains a large fleet of flight-proven boosters to shoulder upcoming missions. The company aims to launch more than 60 Falcon 9 and Falcon Heavy flights in 2023 across its customer base and internal programs like Starlink.
In fact, the next Falcon 9 launch with dozens more Starlink satellites is likely just days away from Cape Canaveral. SpaceX will also debut the enhanced Falcon 9 Block 6 variant and test a towering new mega-rocket called Starship in the coming year.
B1058’s pioneering legacy will live on through continued rocket reusability and insistence that any failure serves as a lesson for future success. Its repeat flights unlocked new operability and cost savings that directly serve ambitions for Mars that it symbolically furthered like no booster before or since.
