Monday's flight was the 11th launch and landing of this particular Falcon 9 first stage, Anderson said. That tied SpaceX's reuse record, which was set by a different Falcon 9 booster during a Starlink launch in December.
The Falcon 9 first stage on this flight, called Starlink 4-8, previously launched SpaceX's Crew Demo-2 flight (the company's first astronaut flight for NASA in 2020), as well as the Anasis-II satellite mission for South Korea, CRS-21 space station cargo mission for NASA, Transporter-1 and Transporter-3 rideshare missions and five different Starlink missions, SpaceX has said.

The two halves of the rocket's nose cone, or payload fairing, also made return trips to space on the flight, each flying on their third mission, Anderson said.
"Improvements on the fairings and our overall refurbishment process has decreased the impact of water landings handled to an overall fairing recovery rate of 93% over the last 14 missions," she added.

SpaceX had already launched three big Starlink batches this year — two in January and one on Feb. 3. The Feb. 3 mission ran into serious trouble, however, thanks to a solar eruption, which triggered a geomagnetic storm here on Earth.
That storm increased atmospheric density, boosting drag on the newly launched Starlink satellites. As a result, up to 40 of the 49 spacecraft came crashing back to Earth, SpaceX representatives said.
SpaceX is apparently targeting a higher orbit in which to release its new Starlink satellites on today's flight, according to Spaceflight Now, which reduced the number of satellties from 49 to 46. They will be deployed in a near-circular target orbit that will range between 202 miles and 209 miles (325-337 kilometers) at its highest and lowest points, Spaceflight Now reported.
