Juno in launch configuration. Juno is a NASA space probe orbiting the planet Jupiter.It was built by Lockheed Martin and is operated by NASA 's Jet Propulsion Laboratory.The spacecraft was launched from Cape Canaveral Air Force Station on August 5, 2011 UTC, as part of the New Frontiers program.

On 5 July 2016, spacecraft Juno arrived and entered the planet's orbit—the second craft ever to do so. Sending a craft to Jupiter is difficult, mostly due to large fuel requirements and the effects of the planet's harsh radiation environment. The first spacecraft to visit Jupiter was Pioneer 10 in 1973, followed a year later by Pioneer 11.
Planetary exploration activities took center stage with the orbit insertion of NASA's Juno probe at Jupiter on 4 July, followed by the launch of NASA's OSIRIS-REx mission to asteroid 101955 Bennu on 8 September. Finally, on 30 September, the Rosetta probe executed a slow crash-landing on comet 67P/Churyumov–Gerasimenko. [8] [9]
Mission Spacecraft Launch date Carrier rocket Operator Mission Type Outcome 1 Pioneer 11: Pioneer 11: 6 April 1973: Atlas SLV-3D Centaur-D1A [3] NASA: Flyby Successful First probe to reach Saturnian system. Closest approach on 1 September 1979 at 16:31 UTC. Flew past Iapetus, Dione, Mimas, Tethys, Enceladus, Rhea and Titan at long distances.
The spacecraft was mounted atop a Juno II launch vehicle with the serial AM-16. [4] It was launched on 16 July 1959, at 16:37:03 GMT , from Cape Canaveral Launch Complex 5 (LC-5). [ 5 ] Immediately after liftoff, a short circuit of the launch vehicle's guidance system caused the Rocketdyne S-3D engines to gimbal , tilting the rocket sharply to ...

November 26 France: Asterix: Diamant A: Earth Success: First French satellite. First orbital launch outside U.S. and Soviet Union. November 29 Canada: Alouette 2 ...
Juno ' s orbit is highly elongated and takes it close to the poles (within 4,300 kilometres (2,700 mi)), but then far beyond Callisto's orbit, the most distant Galilean moon. [12] This orbital design helps the spacecraft (and its complement of scientific instruments) avoid Jupiter's radiation belts, which have a record of damaging spacecraft ...
