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.
Highlights this month include the impending arrival of Juno at Jupiter, the approval of extended missions for all of NASA's solar system spacecraft, and public data releases from Rosetta, New Horizons, and Cassini.
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.
It's apparently National Selfie Day. I'm not entirely sure who has the authority to declare these things, or why they decided we needed a National Selfie Day, but since the self-portrait is one of my favorite subgenres of spacecraft photography, I couldn't resist writing about them.
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.
Today ESA released ExoMars Trace Gas Orbiter's first photo of Mars, taken from a distance of 41 million kilometers. It's no more detail than you can get through a pair of a binoculars, just a little taste of what's to come.
Curiosity is at a turning point in its mission to Mount Sharp, both literally and figuratively. Having drilled at three sample sites in 7 weeks, the rover took a left turn, changing its trajectory from a generally westward driving path to a southward one. It is now poised to cross the Bagnold dune field at Murray buttes.
Reporter Nadia Drake has been following the status of Arecibo very closely, and recently wrote two articles explaining what it means that the National Science Foundation has begun an environmental review process for the giant radio telescope.
