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.

Date (UTC) Spacecraft Event Remarks 19 January SLIM: Lunar landing Success [71] Late January Peregrine: Lunar orbit insertion Precluded due to propellant leak developing shortly after launch. [72] 3 February Juno: 58th perijove On the day of this perijove, Juno flew by Io at a distance of 1,500 km. Orbital period around Jupiter reduced to 33 ...
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.
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 Galileo spacecraft would be launched by the STS-34 mission in the Space Shuttle Atlantis. [17] As the launch date of Galileo neared, anti-nuclear groups, concerned over what they perceived as an unacceptable risk to the public's safety from the plutonium in the Galileo 's radioisotope thermoelectric generators (RTGs) and General Purpose ...
The launch vehicle is a member of the Redstone launch vehicle family, and was derived from the Jupiter-C sounding rocket. It is commonly confused with the Juno II launch vehicle, which was derived from the PGM-19 Jupiter medium-range ballistic missile. In 1958, a Juno I launch vehicle was used to launch America's first satellite, Explorer 1.
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 ...
