Juno to delay planned burn
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.
Juno and Marble Movie update at Apojove 1
Juno is on its second of two long orbits around Jupiter, reaching apojove (its farthest distance from the planet) today.
A deep dive into the highest-resolution Voyager Jupiter data
A few weeks before the first Juno high resolution imaging, I decided to take a look at Voyager color images at various resolutions, with particular attention to high-resolution mosaics.
Juno's instruments return riches from first perijove
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?
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
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
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’
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
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.
Jupiter's Clouds: A Primer
With Juno arriving at Jupiter, Justin Cowart gives us a lesson on the giant planet's varied cloud patterns.
Oppositions, conjunctions, seasons, and ring plane crossings of the giant planets
When are the solstices and equinoxes on the giant planets, and when are they best positioned for view from Earth? I ask these questions a lot as I write about Earth photos of giant planets, and I finally decided to gather the answers to those questions in a single post.
Juno has arrived!
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
A peek at the JunoCam approach movie
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.
Juno's first taste of science from Jupiter
Jupiter is growing in Juno's forward view as the spacecraft approaches for its orbit insertion July 5 (July 4 in the Americas). The mission has released images from JunoCam and sonifications of data from the plasma waves instrument as Juno begins to sense Jupiter.
What to expect from JunoCam at Jupiter
Juno will go in to orbit at Jupiter on July 5 (July 4 in North and South American time zones), and it's carrying a camera that's going to take really awesome photos of Jupiter. But you're going to have to be patient. Emily Lakdawalla explains why.
Whither the Weather? A Jet Stream Explainer
Jet streams are found in planetary atmospheres throughout our solar system. But what exactly are they?
Three bright planets: Portraits from the Pyrenees
It's a great time to go outdoors and look at planets. I have three glorious planetary portraits to share today, sent to me by amateur astronomer Jean-Luc Dauvergne.
JunoCam cruise data, and a look ahead to Jupiter
Juno is now fewer than six months and 100 million kilometers away from Jupiter, and the Juno team is busily preparing for the arrival. Amateur astronomers are supporting them by taking lots of Jupiter photos.
Jupiter's Great Red Spot
On the 20th anniversary of Galileo's orbit insertion around Jupiter, amateur image processor Björn Jónsson shares some of the mission's first images of Jupiter's iconic massive storm.
