Early on Saturday morning, SpaceX will go for its third launch in two weeks with another Starlink mission into low Earth orbit. This will bring the total number of Starlink Internet satellites launched to date to nearly 540.
For most US residents, watching this launch will require either real dedication or a severe case of insomnia. The launch of the Starlink-8 mission is scheduled for 5:21am ET (09:21 UTC) from Cape Canaveral Air Force Station. Despite the early hour, the mission is worth tracking for several reasons.
Cadence
On May 30, a Falcon 9 rocket launched the Crew Dragon mission for NASA. And on June 3, a Falcon 9 rocket launched the Starlink-7 mission. Now, SpaceX returns to the pad for this flight, which will be the company's 10th launch of the year.
This would put SpaceX on pace to meet or exceed its record total for an annual number of launches—21 in 2018.
The company appears to be accelerating its cadence of launches after the Crew Dragon mission, which necessitated extra preparation due to the fact that it involved launching humans. It's possible that SpaceX will complete three more launches this month: this one, another Starlink flight, and the launch of a GPS III satellite for the US Space Force.
Starlink rideshare
This will be the first time SpaceX has flown a Starlink mission with other payloads attached, and it's the first of the company's SmallSat Rideshare Program launches. The company will remove two Starlink satellites from its normal stack inside the payload fairing—bringing the total down to 58—to accommodate the launch of three SkySat imaging satellites for Planet. Another Falcon 9 rocket will launch three more SkySats on a subsequent Starlink flight later this summer.
