This Day in Space: 5 August

5 August 2011 – NASA’s Juno spacecraft blasted off from Cape Canaveral aboard an Atlas V rocket, beginning a five-year journey to the Solar System’s largest planet, Jupiter.  The 3.6-tonne spacecraft is scheduled to arrive in July 2016.

The name ‘Juno’ isn’t an acronym or a reference to the Ellen Page/Michael Cera comedy movie.  In Roman mythology Juno was the wife of Jupiter:  When Jupiter drew a veil of clouds around himself to hide his mischief, Juno was able to peer through the clouds and reveal Jupiter’s true nature.  Similarly, the Juno spacecraft will look deep into Jupiter’s obscuring cloud cover – http://www.nasa.gov/mission_pages/juno/news/juno20110805.html.

The 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.

1979: Voyager 2 made its closest approach to Jupiter on this day, passing within 570,000km of the giant planet’s upper atmosphere.

The twin Voyager spacecraft made numerous discoveries in the Jovian system, including active volcanoes on the moon Io (the first discovered beyond Earth), faint rings encircling the planet and previously unknown moons.
