Cygnus OA-6: What’s onboard?

Juno left the Earth atop a United Launch Alliance Atlas 5 rocket on Aug. 5, 2011, beginning its journey to Jupiter atop the most powerful Atlas variant with five side-mounted boosters. It arrives at the gas giant on Monday.

Two Russian cosmonauts and a NASA astronaut flying to the International Space Station for a fourth time lifted off Friday at 2126 GMT (5:26 p.m. EDT) from the Baikonur Cosmodrome in Kazakhstan. The trio reached the orbiting research complex less than six hours later at 0309 GMT (11:09 p.m. EDT).

Astronauts Drew Morgan and Christina Koch floated back outside the International Space Station Friday and completed work to replace six aging batteries with three more powerful units in one of the lab’s eight solar power circuits. Three more spacewalks are planned over the next two weeks to replace another six batteries in an adjacent circuit.
