Watch live today: SpaceX launching advanced GPS satellite for the US Space Force, ,
A SpaceX Falcon 9 rocket will launch a Global Positioning System (GPS) satellite for the U.S. Space Force on Thursday (June 17), and you can watch it live here.
The GPS III Space Vehicle 05 mission will lift off from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida during a 15-minute launch window that opens at 12:09 p.m. EDT (1609 GMT). After delivering the payload to orbit, the Falcon 9 rocket will return to Earth for a landing at sea.

Find out what the astronauts and cosmonauts aboard the International Space Station are up to by tuning in to the “ISS Live” broadcast. Hear conversations between the crew and mission controllers on Earth and watch them work inside the U.S. segment of the orbiting laboratory. When the crew is off duty, you can enjoy live views of Earth from Space. You can watch and listen in the window below, courtesy of NASA.
“Live video from the International Space Station includes internal views when the crew is on-duty and Earth views at other times. The video is accompanied by audio of conversations between the crew and Mission Control. This video is only available when the space station is in contact with the ground. During ‘loss of signal’ periods, viewers will see a blue screen.
“Since the station orbits the Earth once every 90 minutes, it experiences a sunrise or a sunset about every 45 minutes. When the station is in darkness, external camera video may appear black, but can sometimes provide spectacular views of lightning or city lights below.”
