Data collected by NASA’s Juno spacecraft utilizing its Jovian InfraRed Auroral Mapper (JIRAM) instrument level to a brand new warmth supply near the south pole of Io that would indicate a beforehand undiscovered volcano on the small moon of Jupiter. The infrared data have been collected on Dec. 16, 2017, when Juno was about 290,000 miles (470,000 kilometers) away from the moon.
“The new Io hotspot JIRAM picked up is about 200 miles (300 kilometers) from the nearest previously mapped hotspot,” stated Alessandro Mura, a Juno co-investigator from the National Institute for Astrophysics in Rome. “We are not ruling out movement or modification of a previously discovered hot spot, but it is difficult to imagine one could travel such a distance and still be considered the same feature.”
The Juno group will proceed to guage data collected on the Dec. 16 flyby, in addition to JIRAM data that will likely be collected throughout future (and even nearer) flybys of Io. Past NASA missions of exploration which have visited the Jovian system (Voyagers 1 and a couple of, Galileo, Cassini and New Horizons), together with ground-based observations, have positioned over 150 lively volcanoes on Io thus far. Scientists estimate that about another 250 or so are ready to be found.
Juno has logged practically 146 million miles (235 million kilometers) since getting into Jupiter’s orbit on July four, 2016. Juno’s 13th science cross will likely be on July 16.
Juno launched on Aug. 5, 2011, from Cape Canaveral, Florida. During its mission of exploration, Juno soars low over the planet’s cloud tops — as shut as about 2,100 miles (three,400 kilometers). During these flybys, Juno is probing beneath the obscuring cloud cowl of Jupiter and finding out its auroras to study extra concerning the planet’s origins, construction, ambiance and magnetosphere.
JPL manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute in San Antonio. The Juno mission is a part of the New Frontiers Program managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the Science Mission Directorate. The Italian Space Agency (ASI), contributed two devices, a Ka-band frequency translator (KaT) and the Jovian Infrared Auroral Mapper (JIRAM). Lockheed Martin Space, Denver, constructed the spacecraft. JPL is a division of Caltech in Pasadena, California.
