Planetary discovery over the past quarter century

Posted by Steven Hauck on 2016/12/20 10:01 CST

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.

What's up in the solar system, November 2016 edition: Cassini takes a leap, ExoMars starts science, Long March 5 launch

Posted by Emily Lakdawalla on 2016/11/01 03:35 CDT | 2 comments

Cassini is going to make a major change to its orbit, getting much close to Saturn, setting up 20 "F-ring" orbits. ExoMars will get two science orbits before beginning aerobraking. Long March 5 will have its first launch, while many Earth-observing missions, including Himawari-9 and GOES-R, will go up. But Juno science is on hold.

Juno to delay planned burn

Posted by Emily Lakdawalla on 2016/10/16 04:28 CDT | 5 comments

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.

What's up in the solar system, October 2016 edition: ExoMars arrives!

Posted by Emily Lakdawalla on 2016/10/04 06:42 CDT | 2 comments

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's instruments return riches from first perijove

Posted by Emily Lakdawalla on 2016/09/02 02:30 CDT | 3 comments

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.

Will Juno’s Instruments Observe the Moons of Jupiter?

Posted by Candice Hansen on 2016/08/30 10:38 CDT | 2 comments

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.

Juno's first Jupiter close approach successful; best JunoCam images yet to come

Posted by Emily Lakdawalla on 2016/08/27 08:07 CDT | 13 comments

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.

JunoCam "Marble Movie" data available

Posted by Emily Lakdawalla on 2016/08/22 04:56 CDT | 11 comments

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 other ‘cameras’

Posted by Anna Scott on 2016/08/16 10:57 CDT | 3 comments

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.

JunoCam raw data from the Juno approach movie

Posted by Emily Lakdawalla on 2016/08/09 03:03 CDT | 1 comments

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.

What's up in the solar system, August 2016 edition: Juno to get Jupiter close-ups, Rosetta descending, road-tripping rovers

Posted by Emily Lakdawalla on 2016/07/29 02:35 CDT | 5 comments

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.
