SpaceX has won an $80 million contract to launch a NASA environmental research satellite aboard a Falcon 9 rocket from Cape Canaveral in late 2022 to collect data on ocean ecosystems and clouds, a mission that the Trump administration wished to cancel.

Forecasters predict mostly cloudy conditions and a chance of light rain for Tuesday morning’s scheduled takeoff of a SpaceX Falcon 9 rocket with a space station-bound supply ship, with a 40 percent chance weather could prevent liftoff during an instantaneous predawn launch opportunity.
