Features Of Nasa’s Juno Spacecraft

Juno is a NASA New Frontiers mission currently en route to the planet Jupiter. Juno was launched from Cape Canaveral Air Force Station on August 5, 2011 and is projected to arrive on July 4, 2016. It is expected to arrive at Jupiter on July 4, 2016.

If successful, Juno will be only the second long-term mission at Jupiter after the Galileo spacecraft of the 1990s and 2000s. However, Juno’s mission is planned to last for a much shorter period, as it is currently being targeted to impact Jupiter in February 2018.


Juno is one of three New Frontiers probes that NASA is currently operating or building. The others are New Horizons, which flew by Pluto in 2015, and OSIRIS-REx, which is expected to fly to asteroid 101955 Bennu in 2020 to collect a sample and return it to Earth. New Frontiers was a program NASA created in 2003 for medium-sized missions that are capped at $1 billion in development and launch costs each.

Long Term Stay At Jupiter

Juno is on a five-year cruise to Jupiter, with arrival expected on 4 July 2016. Several spacecraft have flown by Jupiter en route to other locations in the solar system . Even during the brief flybys, they have been able to glimpse interesting information about Jupiter and its moons.


Juno was originally proposed at a cost of approximately US$700 million for a June 2009 launch. NASA budgetary restrictions resulted in postponement until August 2011, and a launch on board an Atlas V rocket in the 551 configuration. As of June 2011, the mission was projected to cost $1.1 billion over its life.
