On Sunday morning, SpaceX reached another important milestone, launching another 60 Starlink Internet satellites.

These Starlink releases have become commonplace,And dare we say, a little boring?— SpaceX has established its own constellation, which can provide broadband Internet to the world from low earth orbit. However, the speed at which SpaceX began to reuse the first phase of its Falcon 9 is definitely not monotonous.

In its launch on Sunday morning, SpaceX used the first stage, which had previously flown into space nine times. After launch, the B1

051 booster landed safely on the unmanned ship, completing its tenth flight. This is an important milestone because in 2018, SpaceX founder Elon Musk stated that the goal of the Falcon 9 rocket is to fly 10 times on each first stage booster, and then Perform extensive maintenance.

Musk recently stated that due to the increasing number of flights in the first phase of Falcon 9, the company has not found any sought-after goods. The company plans to continue to use these older rockets for Starlink missions, thus risking its own in-flight payloads instead of paying customers’ payloads. Musk said the company has not set any predetermined limits on the life of the Falcon 9 rocket, and SpaceX will fail certain parts of its Falcon 9 rocket to find these limits.

This particular first phase entered orbit for the first time on March 2, 2019. This is the first demonstration mission planned by NASA’s commercial crew. During the flight, the Crew Dragon spacecraft docked at the International Space Station for about five days, paving the way for the first manned flight in May 2020. This first phase was also used to launch two commercial satellites and seven Starlink missions.

It is now approaching historical status. B1051 only lags behind NASA’s Find, Atlantis, Colombia, with struggle As far as aerospace is concerned, it is the orbiter of the space shuttle. Three of these shuttles are now in the museum. Colombia He was killed in a fatal accident in 2003.

Since early March 2019, this booster has flown 10 times and has now completed almost the same flight mission as SpaceX’s main US launch competitor. Since the first flight of the B1051, the United Launch Alliance has performed 11 expendable rocket missions, including two Delta IV launches, two Delta IV Heavy missions and seven Atlas V rockets.

Thanks to its ability to reuse rockets, SpaceX can improve its launch rhythm. Especially this year, the company’s development speed is very fast. Through Sunday’s launch, SpaceX launched 14 orbital missions in 2021, 11 of which were Starlink flights. This is launched every 9 days on average, and these missions are only distributed in six different Falcon 9 first phases.

The company’s next orbital launch is its 27th operational Starlink satellite, which may be launched as early as this Saturday from the Kennedy Space Center in Florida.
