Live coverage: Two satellites lift off aboard Ariane 5

European Space Agency Director General Josef Aschbacher said Thursday the Ariane 6 is expected to launch for the first time between June 15 and July 31, 2024. The determination comes on the heels of what ESA determined to be a successful hot fire test of the rocket’s main engine.

SpaceX launched the first of the company’s upgraded generation of Falcon 9 launchers, known as Block 5, from the Kennedy Space Center on Friday at 4:14 p.m. EDT (2014 GMT). The Falcon 9 rocket lifted off with Bangladesh’s first communications satellite, and SpaceX recovered the rocket’s first stage on a vessel in the Atlantic Ocean.
