Where to watch Juno Spacecraft
Juno will begin start its main engine at 20:18 PT / 23:18 ET July 4, here’s how you can follow the mission. NASA TV will begin broadcasting live beginning 19:30 PT / 22:30 ET / 02:30 UT. You can watch NASA TV online here, or via UStream. To get a good idea of Juno’s approach you can watch a neat amateur-produced visualization at lizard-tail.com, made by Isana Kashiwai and Go Miyazaki.
Below is a timeline of the remaining Juno mission events until orbit insertion. All Juno spacecraft events are in Earth’s Received Time or the time factoring in the 48 minutes it takes for radio signals from Juno to reach us.
