VideoWith 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.
NASA must decide soon on Dawn mission’s next act
NASA managers face a July 12 deadline to decide whether to send the Dawn spacecraft on an unplanned visit to a third object in the asteroid belt or keep the probe at dwarf planet Ceres until it runs out of fuel next year, officials said this week.
Juno’s British-built engine readied for all-important firing at Jupiter
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.
Oxygen finding strengthens case that Mars was once habitable
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 than than previously thought, scientists said Monday.
New and improved space weather observatory goes live next month
NOAA's Deep Space Climate Observatory, a $340 million mission that spent more than a decade grounded in a Maryland warehouse, will begin warning forecasters of dangerous solar storms next month, giving notice of events that could disrupt air travel, radio communications, electrical grids and satellite operations.
Jupiter and its satellites seen by ‘people’s camera’ on Juno probe
The visible camera on NASA's Juno spacecraft is capturing a time-lapse movie of Jupiter and its four largest moons as the orbiter dives toward the giant planet for a July 4 rendezvous, and officials have released a first taste of the views armchair scientists and space enthusiasts can anticipate over the coming weeks and months.
Juno right on target for July 4 rendezvous with Jupiter
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.
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.
Q&A with Scott Bolton, principal investigator on NASA’s Juno mission
Scott Bolton of the Southwest Research Institute leads the science team on NASA's Juno mission, a robotic spacecraft now on final approach to Jupiter designed to probe the giant world's deep interior and unravel how the solar system's king planet formed.
Japanese orbiter officially begins science mission at Venus
Five months since a belated arrival at Venus, Japan's Akatsuki spacecraft has officially started a modified scientific survey of the sweltering, shrouded planet's atmosphere and climate.
