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.
The big day is almost here. Juno begins firing its main engine at 20:18 PT / 23:18 ET / 03:18 UT on July 4/5, and the maneuver should be over 35 minutes later at 20:53 / 23:53 / 03:53. Here's how you can follow the mission through its most hazardous event since launch.
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.
Today NASA held a press briefing and released a press kit for the impending orbit insertion of the Juno spacecraft. The 35-minute orbit insertion burn is scheduled to begin July 5 at 03:18 UTC (July 4 20:18, PDT). Here's a timeline for events relating to orbit insertion.
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.
May 2016 will be yet another month of fairly routine operations across the solar system -- if you can ever use the word "routine" to describe autonomous robots exploring other planets. ExoMars' cruise to Mars has started smoothly, and Juno is only two months away from Jupiter orbit insertion. Earthlings will witness a Mercury transit of the Sun on May 9.
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.
I'm back from two weeks' vacation, so it's time to catch up on the status of all our intrepid planetary missions, from Akatsuki to the Voyagers and hitting the Moon, Mars, asteroids, comets, and Saturn in between.
With the New Year upon us, what can we look forward to in 2014? For me, the main event of 2014 is that ESA's Rosetta mission finally -- finally! -- catches up to the comet it has been chasing for a decade. We will lose LADEE, gain two Mars orbiters, and launch Hayabusa2. The year begins with an amazing 24 spacecraft exploring or cruising toward various planetary destinations.
Juno's Earth flyby represented the first opportunity for many of the science instruments to be used on a planetary target. There were terrific photos of Earth and the Moon, plus a cool project to see if Juno could detect intelligent life on Earth.
A close look at two international planetary science poster presentations from the 2013 AGU Fall Meeting featuring sediment experiments to better understand Martian geomorphology and Juno's plans for exploring Jupiter's ring system.
After entering safe mode last week during its Earth flyby, Juno returned to normal operations and downlinked all engineering and science instrument data. It entered safe mode again on Sunday night, but it is expected to re-resume normal operations late next week.
Following its Earth flyby earlier today, Juno is in safe mode. This is the protective state a spacecraft goes into when it detects a problem. But everything is okay. For more details, I just spoke with Rick Nybakken, Juno Project Manager at the Jet Propulsion Laboratory.
