After three-year wait, commercial imaging observatory shipped for launch
WorldView 4. Credit: Lockheed Martin More than three years after its launch was delayed by a corporate merger, a commercial Earth-imaging satellite has finally shipped to its California rocket base for liftoff aboard an Atlas 5 in September. The WorldView 4 spacecraft, built by Lockheed Martin, was moved this week from its factory in Sunnyvale…

Researchers eager for Juno’s first chance for Jupiter science
Animation of Juno 14-day Orbits Starting in late 2016. Juno is currently in an even larger 53-day orbit. Credit: NASA/JPL-Caltech NASA’s Juno spacecraft fine-tuned its orbit around Jupiter this week, helping steer the spinning space probe on a course to dip beneath the giant planet’s radiation belts in late August for the first time with…

Navy’s new MUOS 5 communications satellite experiences snag in space
MUOS 5 in the factory. Credit: Lockheed Martin CAPE CANAVERAL — 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. The $340 million Mobile User Objective System…

Video: When Juno launched to begin 5-year trek to Jupiter
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. Liftoff occurred at 12:25 p.m. EDT (1625 GMT) from Complex 41 at Cape Canaveral, Florida. After traveling more than 1.7 billion miles, Juno arrives…

Juno switched to autopilot mode for Jupiter final approach
Artist’s concept of the Juno spacecraft at Jupiter. Credit: NASA/JPL-Caltech Four days out from arriving at the solar system’s biggest planet, NASA’s Juno spacecraft received a final uplink of commands Thursday governing the robotic probe’s high-velocity braking maneuver Monday to steer into orbit around Jupiter. Juno will run on autopilot for the rest of its…
