CAPE CANAVERAL, Florida – The launch of a SpaceX Falcon 9 rocket carrying 57 Starlink and 2 BlackSky satellites that was scheduled to liftoff today, Friday, June 26, 2020, at 4:18 p.m. Eastern Daylight Time from Launch Complex 39A at Kennedy Space Center in Florida has been scrubbed.
A new launch date has not yet been announced.
Standing down from today’s Starlink mission; team needed additional time for pre-launch checkouts, but Falcon 9 and the satellites are healthy. Will announce new target launch date once confirmed on the Range

Launch Weather 80% ‘GO’
According to the latest forecast from the U.S. Space Force 45th Weather Squadron, there is an 80% chance of favorable weather for launch.
The primary weather concerns are anvil clouds and cumulus clouds.
Attempted Landing On Drone Ship
Following stage separation, the first stage of the Falcon 9 Block 5 will attempt a landing on an autonomous drone ship Of Course I Still Love You in the Atlantic Ocean.
This is the ninth operational launch of 57 Starlink satellites into orbit. And the second rideshare launch with other satellites.
Targeting tomorrow, June 26 at 4:18 p.m. EDT for launch of 57 Starlink satellites and 2 spacecraft from @SpaceflightInc’s customer BlackSky

The 57 Starlink satellites are part of a next-generation satellite network developed by SpaceX to provide the globe with reliable and affordable broadband internet services.
Each Starlink satellite weighs approximately 500 lbs. (227kg) and features a flat-panel design with multiple high-throughput antennas and a single solar array.
SpaceX designed Starlink to connect end-users with low latency, high bandwidth broadband services by providing continual coverage around the world using a network of thousands of satellites in low Earth orbit.
Starlink Hall Thruster
Starlink satellites feature Hall thrusters powered by krypton to adjust position on orbit, maintain intended altitude, and de-orbit.
A Hall thruster is a type of electric propulsion device that produces thrust by ionizing and accelerating a noble gas, usually xenon.
While producing comparatively low thrust relative to conventional rocket engines, Hall thrusters provide significantly greater specific impulse or fuel economy.
This results in increased payload carrying capacity and a greater number of on-orbit maneuvers for a spacecraft using Hall thrusters rather than traditional rocket engines.
Starlink Space Junk Avoidance
Starlink satellites are capable of tracking on-orbit debris and autonomously avoiding a collision.
95 percent of all components of this Starlink satellite design will quickly burn in Earth’s atmosphere at the end of each satellite’s life-cycle which exceeds all current safety standards.
