Juno Spacecraft's July 4 Jupiter Arrival: What to Expect

9:16 p.m. EDT (0116 GMT) Monday: Juno begins slowly turning away from the sun and toward its orbit-insertion orientation. Another, faster turn toward this orientation begins at 10:28 p.m. EDT (0228 GMT). (These maneuvers and all other aspects of the orbital-insertion plan are pre-programmed; the spacecraft has been on autopilot since June 30.)

10:41 p.m. EDT (0241 GMT): Juno switches over to its low-gain antenna, which the probe will use to send status-updating "tones" during the night's maneuvers, and fine-tunes its orbit-insertion attitude.

10:56 p.m. EDT (0256 GMT): The probe boosts its spin rate from 2 to 5 revolutions per minute (RPM) to increase its stability for the orbit-insertion burn.

11:18 p.m. EDT (0318 GMT): Juno's main engine begins firing in the orbit-insertion burn, which should slow the spacecraft by 1,212 mph (1,950 km/h) and allow it to be captured by Jupiter's gravity into a 53.5-day-long orbit.

11:53 p.m. EDT (0353 GMT): Orbit-insertion burn ends.

11:55 p.m. EDT (0355 GMT): Juno begins reducing its spin rate from 5 RPM back down to 2 RPM, a process that should take about 5 minutes.

12:07 a.m. EDT Tuesday (0407 GMT): The spacecraft begins pointing toward the sun again.

12:11 a.m. EDT (0411 GMT): Juno switches back to its medium-gain antenna.

12:16 a.m. EDT (0416 GMT): The probe starts beaming detailed telemetry information (not just tones) back to Earth. It will likely take about 20 minutes to lock onto Juno's signal, mission team members have said. And data transmission will be far from instantaneous; it currently takes light about 48 minutes to travel from Jupiter back to Earth.

1 a.m. EDT (0500 GMT): NASA and Juno team members will hold a news conference to provide an update about how the orbital insertion went.

Thank you to everyone who has stuck by the YouTube channel and to all of our admins and forum users here on the channel. They really have kept the website current while I have been busy taking care of things in my personal life. I promised that the next video would be a long one and have a LOT to look at. You can get lost in these Gigapans and I really hope that you do! I spent a lot of time stitching these together and making sure that they were the best quality that I could get them. SOL 1448 really has been a goldmine for anomaly hunters and those people who are just hobbiest. I really hope you enjoy this one and expect much more to come from the latest batches of images!
