Watch SpaceX’s 60-satellite Starlink launch tonight right here

SpaceX’s launch tonight is being performed for a very important client: itself. Yes, the Falcon 9 that will lift off at 7:30 PM Pacific time is loaded not with government or commercial payloads, but the first of SpaceX’s own Starlink orbital communications satellites. You can watch this first-of-its-kind launch here.
In the launch press kit (PDF), SpaceX provided new details of the launch, the deployment process and the Starlink satellites themselves, which have only been described in roundabout fashion via regulatory filings and such.
Weighing 500 pounds each, the 60 Starlink satellites add up to around 30,000 lbs of payload, considerably less than the Falcon 9’s upper limit of over 50,000 lbs. I wouldn’t have guessed they were quite as heavy as that — some communications satellites are small enough you could easily lift them with one hand, though others, like OneWeb’s and of course geosynchronous ones, are much larger.
Although that leaves plenty of unused lift capacity, the satellites and their deployment platform take up practically every cubic inch of the Falcon 9’s usable interior. This launch is limited by volume, not mass.
