The first stage’s landing punctuated the fifth trip to space and back for this booster, and it broke a record for the fastest turnaround between flights of a SpaceX booster, besting the previous mark of 38 days set last month.
The booster on Thursday’s mission last flew Jan. 7 with the Turksat 5A communications satellite, just 27 days ago. (...)
In total, the company has launched 1,085 satellites to date, including prototypes and failed spacecraft that are no longer in orbit.
Another 60 Starlink satellites are mounted on a Falcon 9 rocket awaiting liftoff from pad 39A, a few miles north of pad 40 at NASA’s Kennedy Space Center. That launch has been grounded several days to await better weather conditions in the offshore booster landing zone in the Atlantic Ocean.
SpaceX briefly planned to launch both Falcon 9 rockets less than five hours apart early Thursday, but the company said Wednesday afternoon that the mission from pad 39A would be pushed back until Friday morning at 5:14 a.m. EST (1014 GMT) “to allow additional time for pre-launch checks.” (...)
SpaceX plans to launch more Starlink satellites into polar orbit to enable global coverage for maritime and aviation customers, including the U.S. military. The company has regulatory approval to launch around 12,000 Starlink satellites.

But records are there to be broken and SpaceX’s venerable fleet of boosters are certainly not allowing the grass to grow under their Merlin 1D+ engines. With this morning’s mission,
B1060 became the first Falcon 9 to launch twice within one month, having previously launched Turkey’s powerful Türksat 5A geostationary communications satellite on 7 January, only 27 days, 4 hours and 4 minutes earlier. “Rapid reusability,” SpaceX tweeted, “is the key to reducing the cost of traveling to space.” (...)
In less than 32 weeks, B1060 becomes only the sixth Falcon 9 core to fly a fifth mission. She first saw service last 30 June, providing the muscle to boost the Space Force’s third Block III Global Positioning System (GPS) navigation and timing satellite towards Medium Earth Orbit (MEO), about 12,550 miles (20,200 km) above the planet. (...)
Her fourth flight last month sent the 7,700-pound (3,500 kg) Türksat 5A on the first leg of its trek up to geostationary altitude, some 22,300 miles (35,900 km) above Earth.
With this morning’s launch, B1060 has flown five times in only 219 days, an empirical SpaceX record. (...)
Finally, on Wednesday afternoon SpaceX revealed that B1049 would have to endure yet another day of delay. “To allow additional time for pre-launch checks”, the Hawthorne, Calif.-headquartered organization explained, its launch was being moved to 5:14 a.m. EST Friday.
And for the second time in less than six months, this eliminated the possibility of Falcon 9s flying twice on the same day. But if B1049 flies tomorrow it will be the first time that two of SpaceX’s birds will have launched on two successive days. (...)
