Decades in the making, Solar Orbiter finally meets launcher at Cape Canaveral
The European-built Solar Orbiter spacecraft was installed on top of its United Launch Alliance Atlas 5 launcher Friday at Cape Canaveral, ready for final charging and checkouts before liftoff Feb. 9 to finally begin a more than $1.5 billion science mission first approved by the European Space Agency nearly 20 years ago.
ULA team completes countdown practice run before Solar Orbiter launch
United Launch Alliance teams loaded super-cold liquid hydrogen and liquid oxygen into an Atlas 5 rocket Friday at Cape Canaveral during a countdown dress rehearsal for a planned launch next month with the Solar Orbiter mission, a robotic spacecraft to study the origins of the solar wind and image the sun’s poles for the first time.
