At 3:37 p.m. today, a SpaceX Falcon 9 rocket will lift off with 60 Starlink internet satellites from Kennedy Space Center’s historic pad 39A. Poor anticipated weather conditions forced SpaceX to move the scheduled Thursday afternoon liftoff date to Wednesday. The weather forecast past Thursday doesn’t look much better, hence the move to this afternoon.

“With a more favorable weather forecast for launch and landing, now targeting Wednesday,” SpaceX said via Twitter on Monday.

Mostly dry conditions and light winds should make today’s scheduled very favorable, but if a push until tomorrow takes place. the launch forecast drops to 50% “go” because of a high probability of afternoon storms.

This mission will mark the seventh under the Starlink mission, which which is focused on creating high-speed internet connectivity from anywhere in the world.

This launch will bring the total of satellites orbiting to 400 satellites with a goal of having thousands of small satellites orbiting the Earth at all times. The internet connectivity could begin rolling out as soon as later this year.
