One of these ride-along NASA efforts is the Athena EPIC (Economical Payload Integration Cost) SmallSat, which will demonstrate a new way of more efficiently placing remote-sensing (or rather, Earth-observing) instruments into orbit.

Two NASA satellites rocketed into orbit from California aboard a SpaceX Falcon 9 rocket Wednesday, commencing a $170 million mission to study a phenomenon of space physics that has eluded researchers since the dawn of the Space Age.

SpaceX Falcon 9 rocket will launch from Vandenberg in California on a NASA mission. Where are some spots to watch liftoff? Will there be a sonic boom?

Endeavour is scheduled to launch atop a Falcon 9 rocket from Pad 39A — the liftoff site of most Apollo moon missions, including Apollo 11 — on July 31, kicking off SpaceX's Crew-11 mission to the International Space Station (ISS) for NASA.

Trump may slash environmental rules for rocket launches. The Trump administration is considering slashing rules meant to protect the environment and the public during commercial rocket launches, changes that companies like Elon Musk's SpaceX have long sought,

The next satellites SpaceX helps to deliver to orbit from Vandenberg won't be its own, but rather two of NASA's on a scientific mission.

NASA has elected to find new sealant material to address helium leaks and explore several hardware changes to deal with what was determined to be overheated thrusters.
