Video: Juno’s countdown to Jupiter

NASA’s Juno spacecraft will stay in its current long-period orbit around Jupiter until at least February, and perhaps longer, as engineers study balky valves inside the science probe’s propulsion system and an unexpected computer reboot that interrupted key functions of the orbiter earlier this month.

Likened to raising a cellular tower 22,300 miles high, a United Launch Alliance Atlas 5 rocket will put the Navy’s fourth mobile communications satellite into space to expands the rugged smartphone system to global coverage.

Nearly two months after NASA’s Juno spacecraft slipped into orbit around Jupiter, the solar-powered probe made a passage 2,600 miles over the giant planet’s colorful banded clouds Saturday, the closest planned encounter during its 20-month exploration of the solar system’s largest world.
