UPDATE for 10 am ET: SpaceX has called off today's planned launch of 57 Starlink satellites and two BlackSky Global satellites in order to perform extra rocket checks. You can read our full story here.
Standing down from today's launch of the tenth Starlink mission to allow more time for checkouts; team is working to identify the next launch opportunity. Will announce a new target date once confirmed with the RangeJuly 11, 2020
A Falcon 9 rocket is scheduled to launch the Starlink mission at 10:54 a.m. EDT (1454 GMT), after a weather delay as well as an earlier delay to allow more checks with its Falcon 9 rockets. The mission is carrying 57 Starlink satellites and two BlackSky Global Earth-observing satellites under a rideshare agreement with Spaceflight Inc.
The first-stage booster for this flight is making its fourth trip to space. It was used to launch SpaceX's uncrewed Demo-1 Crew Dragon mission in 2019, three Radarsat satellites for Canada and another Starlink mission earlier this year. The booster is expected to land on SpaceX's drone ship "Of Course I Still Love You" in the Atlantic Ocean shortly after liftoff.
SpaceX is targeting Saturday, July 11 at 10:54 a.m. EDT, 14:54 UTC, for launch of its tenth Starlink mission, which will include 57 Starlink satellites and 2 satellites from BlackSky, a Spaceflight customer. Falcon 9 will lift off from Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida.
Falcon 9’s first stage previously supported Crew Dragon’s first demonstration mission to the International Space Station, launch of the RADARSAT Constellation Mission, and the fourth and seventh Starlink missions. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Of Course I Still Love You” droneship, which will be stationed in the Atlantic Ocean.
You can watch the launch webcast here, starting about 15 minutes before liftoff. If you would like to receive updates on Starlink news and service availability in your area, please visit starlink.com.
The BlackSky Global spacecraft will deploy sequentially beginning 1 hour and 1 minute after liftoff, and the Starlink satellites will deploy approximately 1 hour and 32 minutes after liftoff. Starlink satellites will be deployed in a circular orbit, as was done on the first through fourth Starlink missions. Additionally, all Starlink satellites on this flight are equipped with a deployable visor to block sunlight from hitting the brightest spots of the spacecraft – a measure SpaceX has taken as part of our work with leading astronomical groups to mitigate satellite reflectivity.
'ISS Live!' Tune in to the space station
Find out what the astronauts and cosmonauts aboard the International Space Station are up to by tuning in to the "ISS Live" broadcast. Hear conversations between the crew and mission controllers on Earth and watch them work inside the U.S. segment of the orbiting laboratory. When the crew is off duty, you can enjoy live views of Earth from Space. You can watch and listen in the window below, courtesy of NASA.
"Live video from the International Space Station includes internal views when the crew is on-duty and Earth views at other times. The video is accompanied by audio of conversations between the crew and Mission Control. This video is only available when the space station is in contact with the ground. During 'loss of signal' periods, viewers will see a blue screen.
"Since the station orbits the Earth once every 90 minutes, it experiences a sunrise or a sunset about every 45 minutes. When the station is in darkness, external camera video may appear black, but can sometimes provide spectacular views of lightning or city lights below."
