JunoCam may be an outreach instrument, but its superb photos of storms on Jupiter are providing plenty of data for scientists to talk about.
At the American Geophysical Union meeting, members of the Juno team showed observations of active volcanism on Jupiter's moon Io.
Image processor Björn Jónsson shares some of his latest stunning images of Jupiter, created using data from NASA's Juno spacecraft.
There's no verdict quite yet on the giant planet's core, and scientists are still gathering clues about the accuracy of our current solar system formation models.
2016 marks the 25th anniversary of the creation of what has become one of the primary venues for the publication of research in planetary science: the Journal of Geophysical Research: Planets. This occasion is a good opportunity to look back at what we have learned in this era of expanded exploration and to try to take a peek at the future.
Cassini is going to make a major change to its orbit, getting much close to Saturn, setting up 20
The Juno mission posted a status report late Friday afternoon, indicating that they will not perform the originally planned period reduction maneuver during their next perijove (closest approach to Jupiter) on October 19. The delay changes the start date of the science mission and also all the future dates of Juno's perijoves.
ExoMars Trace Gas Orbiter arrives on October 19, and it will deliver the Schiaparelli lander to its brief life on the Martian surface. Juno's headed into its science orbit, MOM has released science data, and New Horizons will finally finish downlinking Pluto flyby data.
Juno is on its second of two long orbits around Jupiter, reaching apojove (its farthest distance from the planet) today.
Cassini ends a year from today, which is sad. But the final year of the mission is going to be awesome.
On August 27, Juno soared across Jupiter's cloud tops from pole to pole, with all instruments operating. NASA posted some terrific first results from several of the instruments today. And the JunoCam team released all 28 raw images taken during the close encounter.
It is not easy to observe Jupiter’s moons as more than points of light with Juno, because Juno will never get very close to any of the moons, but as its orbit shifts there will be opportunities to collect data on some of the moons.
NASA announced this afternoon that Juno passed through its first perijove since entering orbit successfully, with science instruments operating all the way. This is a huge relief, given all the unknowns about the effects of Jupiter's nasty radiation environment on its brand-new orbiter.
Since a few days after entering orbit, JunoCam has been taking photos of Jupiter every fifteen minutes, accumulating a trove of data that can be assembled into a movie of the planet.
Juno’s science goals are to understand the origin and interior of Jupiter, focusing specifically on its atmosphere and magnetic field. Cameras can help answer some of these questions.
As it approached Jupiter from June 12 to 29, JunoCam captured an animation of the major moons orbiting the planet. The mission released a processed version of the animation on the day of orbit insertion, but took a few weeks to release the raw image data. I've prepared a page hosting all the raw data, and share a few processed versions.
This month we'll finally see JunoCam's first high-resolution images of Jupiter. We'll also see OSIRIS-REx making progress toward its September 8 launch. Both rovers are road-tripping at Mars, while ExoMars Trace Gas Orbiter has completed a major mid-course correction ahead of its October arrival.
With Juno arriving at Jupiter, Justin Cowart gives us a lesson on the giant planet's varied cloud patterns.
For a second time, NASA has placed a spacecraft into orbit at Jupiter. The spacecraft operated exactly according to plan, and Juno successfully entered orbit today, July 5, 2016, UTC
We're now just about 12 hours away from Juno's Jupiter orbit insertion. As anticipation ramps up, NASA has released this sneak peek at JunoCam's approach movie, made of views of Jupiter and its largest moons shot during the final approach, up until about five days ago.
