Live coverage: SpaceX Falcon Heavy launches NASA’s Psyche on mission to a metal asteroid

A Falcon 9 rocket powered by a reused first stage booster rolled out Tuesday to pad 39A at NASA’s Kennedy Space Center in Florida, a day before its scheduled liftoff with an Airbus-built communications satellite designed for television broadcasts over the Americas.

The first images from the European-built Solar Orbiter mission are the closest ever taken of the sun, revealing previously unseen mini-flares nicknamed “campfires” that may offer hints about what makes the solar corona, or outer atmosphere, hotter than the sun’s surface.

Forecasters predict a 60 percent chance of favorable weather for launch of a SpaceX Falcon 9 rocket Thursday from NASA’s Kennedy Space Center in Florida to carry more Starlink broadband satellites into orbit.
