From Space.com:
SpaceX's internet-satellite megaconstellation appears to be off to a good start in low-Earth orbit.
The first 60 members of the company's Starlink network launched last night(May 23) atop a Falcon 9 rocket. The satellites deployed smoothly about an hour after liftoff, and they came online shortly thereafter, SpaceX founder and CEO Elon Musk announced via Twitter last night.
Musk gave us another update this afternoon (May 24), tweeting "So far, so good" in response to a follower's question about Starlink's status.
"Krypton thrusters operative, satellites initiating orbit raise every 90 mins," he added in another tweet a bit later. (The satellites deployed at an altitude of 273 miles, or 440 kilometers, and are making their own way to their operational altitude of 342 miles, or 550 km).
