Juno Probe's Jupiter Arrival Tonight Fraught With Peril

The stakes and the risks are high for a NASA spacecraft's long-awaited arrival at Jupiter tonight (July 4). The Juno probe is scheduled to enter orbit around Jupiter tonight at 11:53 p.m. EDT (0353 GMT on Tuesday), after a crucial 35-minute engine burn. If something goes seriously wrong with this maneuver, Juno will sail right past the gas giant, and 15 years of mission planning will go out the window.
