May 11: SpaceX launches NASA’s TRACERS mission. A SpaceX Falcon 9 rocket will carry twin synchronized spacecraft to orbit as a part of NASA’s research on the impacts of solar activity on Earth. TRACERS will specifically study magnetic reconnection of Earth’s atmosphere caused by interaction with passing solar activity.

SpaceX launched its 250th dedicated Starlink mission on Sunday night (April 27), sending 23 of the broadband satellites to low Earth orbit.

SpaceX sent another batch of Starlink satellites to orbit tonight (April 28), its second liftoff of the day. It was the second Starlink group to fly today; a Falcon 9 lofted 27 of the internet craft from California's Vandenberg Space Force Base earlier today.
