A SpaceX Falcon 9 first stage designated B1067 completed its 36th flight on July 9, 2026, lifting off from Cape Canaveral again. This time it carried 29 Starlink satellites and returned to a different ship, A Shortfall of Gravitas. The booster touched down at sea about eight and a half minutes after leaving Florida.
The Milestones of Booster B1067
Booster B1067 originally debuted on 3 June 2021, lifting NASA’s CRS-22 cargo mission from Kennedy Space Center. There was no experimental landing profile and no special recovery ceremony. According to historical logbooks, the booster’s career spans multiple mission types. Its manifest has featured commercial communications and navigation payloads alongside NASA’s Crew-3 and Crew-4 flights, including Türksat 5B, Eutelsat HOTBIRD 13G, O3b mPOWER spacecraft, Indonesia’s SATRIA broadband satellite, Telkomsat Merah Putih 2, a Galileo navigation mission, and Koreasat-6A.
Comparing Reusable Stages to Historic Orbiters
With 36 flights completed, B1067 sits within three missions of space shuttle Discovery’s lifetime total of 39. However, comparing a Falcon 9 first stage to a space shuttle orbiter involves very different operational exposures. While Discovery experienced all of ascent, prolonged orbital operation and the much harsher energy of orbital re-entry, B1067 experiences ascent loads, separation, atmospheric return, salt-air recovery and landing, spending only minutes in flight.
Evolution of the Block 5 Design and Maintenance
Falcon 9 Block 5 debuted in May 2018 as the final major version of the rocket. Originally, SpaceX targeted a capability where each first stage booster could execute at least ten flights without requiring major overhauls. That initial figure served as an engineering and maintenance target rather than an automatic expiry date. Fleet management relies on structured inspection protocols described to Aviation Week using airline-like labels, featuring an A check following every flight, a B check around every sixth or seventh mission, and C-level attention for life-leading stages and crewed flights. Company managers discussed replacing selected components proactively and using telemetry to update design, manufacturing and inspection decisions.
A booster structure remaining certifiable for dozens of flights demonstrates structural durability, but payload requirements and mission performance margins ultimately dictate whether a stage is recovered or expended.
Frequently Asked Questions
How many times has booster B1067 flown?
Booster B1067 completed its 36th trip up and 36th controlled return on 9 July 2026, carrying 29 Starlink satellites.
What was B1067’s first mission?
The booster first flew on 3 June 2021, lifting NASA’s CRS-22 cargo mission from Kennedy Space Center.
How does B1067’s flight count compare to the Space Shuttle Discovery?
B1067’s 36 flights put one Falcon 9 first stage within three missions of space shuttle Discovery’s lifetime total of 39, though the two vehicles experienced vastly different operational environments, turnaround times, and structural stresses.
