Juno launched in 2011 from Cape Canaveral

(NASA) – Data collected by NASA's Juno satellite using its JIRM instrument (Jovian InfraRed Auroral Mapper) points to a new heat source near the south pole of Io could indicate a volcano not discovered before. moon of Jupiter. The infrared data was collected on December 16, 2017, when Juno was approximately 470,000 kilometers from the moon.
"The new Io access point recovered by JIRAM is about 300 km from the nearest," said Alessandro Mura, a Juno co-investigator of the National Institute of Astrophysics at Rome. "We do not exclude the movement or modification of a previously discovered hot spot, but it is difficult to imagine that we can travel such a distance and be always considered the same thing. "
The Juno team will continue to evaluate the data collected on December 16th, as well as the JIRAM data that will be collected during the next (and even closer) flyby of Io. NASA explorers who visited the Jovian system (Voyagers 1 and 2, Galileo, Cassini and New Horizons), as well as ground observations, have located more than 150 active volcanoes on Io until now Scientists estimate that about 250 others are waiting to be e discovered
Juno has logged nearly 146 million miles (235 million kilometers) since it entered Jupiter's orbit on July 4, 2016. Juno's 13th science map will be July 16. 19659009] Juno was launched on August 5, 2011 in Cape Canaveral, Florida. During its exploration mission, Juno flies over the cloudy peaks of the planet, nearly 2,100 miles (3,400 kilometers).
During these overflights, Juno probes the cloud cover of Jupiter and studies his aurora borealis to find out more. about the origins, the structure, the atmosphere and the magnetosphere of the planet.
JPL leads the Juno mission of senior researcher Scott Bolton of the Southwest Research Institute in San Antonio. The Juno mission is part of the New Frontiers program run by NASA's Marshall Space Flight Center in Huntsville, Alabama, for the Scientific Missions Directorate
The Italian Space Agency (ASI) provided two instruments, a translator frequency band Ka (KaT) and the jovian infrared auroral mapper (JIRAM). Lockheed Martin Space, Denver, built the spaceship. JPL is a division of Caltech in Pasadena, California.
