NASA's unmanned Juno spacecraft on Monday entered the orbit of planet Jupiter, a major achievement for a $1.1 billion mission that hopes to find the origins of the biggest planet in the solar system.
Annoncing the development, a commentator at mission control at NASA's Jet Propulsion Laboratory in Pasadena, California said, "Welcome to Jupiter."
Braving intense radiation, the NASA spacecraft reached Jupiter after a five-year voyage to begin exploring Jupiter.
The spacecraft's camera and other instruments were switched off for arrival, so there won't be any pictures at the moment it arrives at its destination. Hours before the encounter, NASA released a number of pictures taken last week during the approach, showing Jupiter glowing yellow in the distance, circled by its four inner moons.
NASA's Juno mission's official twitter handle wrote:
"Success! Engine burn complete. #Juno is now orbiting #Jupiter, poised to unlock the planet's secrets."
When the main engine began to roar, the handle had tweeted:
"Main engine burn is go. I?m burnin', burnin', burnin' for you, #Jupiter."
Juno spacecraft has traveled 1.7 billion miles (2.7 billion kilometers) since it was launched five years ago from Cape Canaveral, Florida.
