A project proposed by Elon Musk's SpaceX and the U.S. Air Force to test hypersonic rocket cargo deliveries from a remote Pacific atoll could harm the many seabirds that nest at the wildlife refuge, according to biologists and experts who have spent more than a decade working to protect them.

A routine test turned into a surprise discovery when DARPA’s atmospheric sensors picked up something unexpected—courtesy of a falling SpaceX Falcon 9.

"The phenomenon is highly repeatable. We discovered an unplanned new technique for identifying objects entering the earth's atmosphere."

The U.S. Federal Aviation Administration on Monday said it closed out a review into SpaceX's explosive Starship test flight in January, while another investigation into the rocket's subsequent testing explosion in March remains open.

Who's up for a historic late-night launch? Weather permitting, SpaceX will launch a spacecraft carrying the first people to orbit the earth's poles Monday.

Frozen fuel from the Falcon 9 rocket launched Monday created a luminous display for several minutes, and was seen by people from England to Eastern Europe.

It's time to examine the numbers to evaluate this volatile stock's trajectory after it climbed 350% in the past year.

During the first quarter of the year, 27 orbital rockets took flight from Florida's Space Coast. That equates to a cadence of 108 launches by year's end — a record-breaking pace that would erase last year's record of 93 annual liftoffs.
