Live coverage: NASA’s Juno spacecraft arrives at Jupiter

Trouble has befallen the U.S. Navy’s new communications satellite that was launched from Cape Canaveral two weeks ago, suspending orbit raising maneuvers and leaving the craft half-way between its rocket deployment orbit and a circular geosynchronous orbit.

With a commitment from the Obama administration finally in hand after more than a decade of studies and concept papers, NASA expects to give the green light this year for development of a robotic probe to Jupiter’s icy moon Europa that could launch as soon as 2022.

Speeding through the outer reaches of the solar system nearly 3.8 billion miles from Earth, NASA’s New Horizons spacecraft has awakened from a five-and-a-half month slumber, ready for a second act after its 2015 flyby of Pluto with a New Year’s Day encounter with a primordial world set to become the most distant object ever explored.
