A spacecraft has skimmed the clouds of Jupiter in a record-breaking close approach to the giant planet. Juno activated its whole suite of nine instruments as it soared 2,600 miles above Jupiter’s swirling cloudtops, travelling at 130,000mph, on Saturday, The Guardian reported.
The space agency tweeted that Juno had successfully completed its closest ever fly-by to the planet right on schedule. It is the first of 36 such passes that the craft is scheduled to make over the next 18 months.
Rick Nybakken, Juno’s project manager at Nasa’s Jet Propulsion Laboratory in Pasadena, California, said: “Early post-fly-by telemetry indicates that everything worked as planned and Juno is firing on all cylinders.”
Mission controllers at the space agency expect to capture stunning images and a wealth of scientific data from the approach, but it will take some days for all the data collected to be downloaded to Earth.
“We are getting some intriguing early data returns as we speak,” said Scott Bolton, principal investigator of Juno from the Southwest Research Institute in San Antonio. “It will take days for all the data to be downlinked, and even more to begin to comprehend what Juno and Jupiter are trying to tell us. This is our first opportunity to really take a close-up look at the king of our solar system and begin to figure out how he works.”
Nasa hopes to release a handful of close-up images from JunoCam, the probe’s panoramic colour camera, later this week. They should include the first detailed pictures of Jupiter’s north and south poles.
No spacecraft has flown so near to Jupiter before. The previous record for the closest approach to the planet was set by Nasa’s Pioneer 11 spacecraft, which passed at a distance of 27,000 miles in 1974.
Only one other spacecraft, Galileo, which visited Jupiter and its moons from 1995 to 2003, has orbited the planet. Although it was deliberately crashed on to Jupiter at the end of its mission, it orbited from much further out than Juno.
