NASA's Juno spacecraft is scheduled to enter into orbit around JupiterMonday night (July 4), ending its nearly five-year trek to the solar system's biggest planet.
The key event Monday is a 35-minute engine burn at 11:18 p.m. EDT (0318 GMT on Tuesday), which is designed to slow Juno down enough to be captured by Jupiter's powerful gravity.
If something goes seriously wrong with this burn, the solar-powered Juno will zoom right past the gas giant, and the science goals of the $1.1 billion mission — which include mapping the gravitational and magnetic fields of Jupiter, and characterizing its internal structure — will go unachieved.
