With Juno on Jupiter’s doorstep, Hubble eyes glowing Jovian auroras
Peering a half-billion miles across the solar system, the Hubble Space Telescope has caught a glimpse of brilliant auroras flashing over Jupiter’s north pole as NASA’s Juno orbiter speeds toward the gas giant for a close-up look. Part of Juno’s multi-pronged scientific campaign is aimed to determining how Jupiter’s auroras form and evolve, along with investigations…

Juno’s British-built engine readied for all-important firing at Jupiter
Artist’s concept of the Juno spacecraft’s Leros 1b main engine firing. Credit: NASA/JPL-Caltech Ground controllers pressurized the Juno spacecraft’s propulsion system Tuesday to prep for a July 4 rocket firing by the probe’s UK-made rocket engine that will steer the spinning, solar-powered robot into orbit around Jupiter. Kicking off more than 20 months observing Jupiter’s…

Oxygen finding strengthens case that Mars was once habitable
This scene shows NASA’s Curiosity Mars rover at a location called “Windjana,” where the rover found rocks containing manganese-oxide minerals, which require abundant water and strongly oxidizing conditions to form. Credit: NASA/JPL-Caltech/MSSS High concentrations of manganese oxides found in Martian rocks by NASA’s Curiosity rover indicate the red planet’s atmosphere once had much more oxygen…

Timeline of Juno’s historic arrival at Jupiter
NASA’s Juno spacecraft must complete a carefully-planned sequence of events as it closes in on Jupiter for a make-or-break orbit insertion burn July 4. The timeline posted below shows the schedule of major events in the weeks ahead of Juno’s arrival at Jupiter, plus the minute-by-minute sequence of steps planned for July 4. Times below…

Juno right on target for July 4 rendezvous with Jupiter
Artist’s concept of the Juno spacecraft on approach to Jupiter. Credit: Lockheed Martin NASA’s Juno spacecraft, running on solar power more than 500 million miles from the sun, is on final approach for a Fourth of July arrival at Jupiter for a year-and-a-half campaign of exploration. Engineers this week are preparing the probe for a…

Mars rover re-routed after spinning wheels on steep hillside
A shadow and tracks of NASA’s Mars rover Opportunity appear in this March 22, 2016, image, which has been rotated 13.5 degrees to adjust for the tilt of the rover. The hillside descends to the left into “Marathon Valley.” The floor of Endeavour Crater is seen beneath the underside of a solar panel. Credit: NASA/JPL-Caltech…
