NASA’s solar-powered Juno spacecraft is set to arrive at Jupiter after an almost five-year journey.  Juno will perform a suspenseful orbit insertion maneuver, a 35-minute burn of its main engine, to slow the spacecraft so it can be captured into the gas giant’s orbit. NASA TV coverage of orbital insertion begins on July 4 at 10:30 p.m. EDT.

Juno's Approach to Jupiter

Video above: After five years traveling through space to its destination, NASA's Juno spacecraft will arrive in orbit around ‪Jupiter‬ today, July 4, 2016. This video shows a peek of what the spacecraft saw as it closed in on its destination before instruments were turned off.

Once in orbit, the spacecraft will circle the Jovian world 37 times during 20 months, skimming to within 3,100 miles (5,000 km) above the cloud tops. This is the first time a spacecraft will orbit the poles of Jupiter, providing new answers to ongoing mysteries about the planet’s core, composition and magnetic fields.

JPL manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute in San Antonio. Juno is part of NASA's New Frontiers Program, which is managed at NASA's Marshall Space Flight Center in Huntsville, Alabama, for NASA's Science Mission Directorate. Lockheed Martin Space Systems, Denver, built the spacecraft. The California Institute of Technology in Pasadena manages JPL for NASA.

Juno's name comes from Greek and Roman mythology. The mythical god Jupiter drew a veil of clouds around himself to hide his mischief, and his wife -- the goddess Juno -- was able to peer through the clouds and reveal Jupiter's true nature.
