Its science \ncollection began in earnest on the Aug. 27, 2016, flyby. During these \nflybys, Juno&#8217;s suite of sensitive science instruments probes beneath the\n planet&#8217;s obscuring cloud cover and studies Jupiter&#8217;s auroras to learn \nmore about the planet&#8217;s origins, interior structure, atmosphere and \nmagnetosphere.<\/p>\n\n\n\n<p style=\"text-align:left\">&#171;We have already rewritten the textbooks on how <a href=\"https:\/\/www.jpl.nasa.gov\/news\/news.php?feature=7075\">Jupiter&#8217;s atmosphere<\/a> works, and on the <a href=\"https:\/\/rdcu.be\/5S5t\">complexity and asymmetry of its magnetic field<\/a>,&#187;\n said Scott Bolton, principal investigator of Juno, from the Southwest \nResearch Institute in San Antonio. &#171;The second half should provide the \ndetail that we can use to refine our understanding of the depth of \nJupiter&#8217;s zonal winds, the generation of its magnetic field, and the \nstructure and evolution of its interior.&#187;<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"alignright\"><img loading=\"lazy\" decoding=\"async\" width=\"320\" height=\"960\" src=\"http:\/\/energyholding.world\/wp-content\/uploads\/2019\/03\/pia22932.png\" alt=\"\" class=\"wp-image-2589\" srcset=\"http:\/\/energyholding.world\/wp-content\/uploads\/2019\/03\/pia22932.png 320w, http:\/\/energyholding.world\/wp-content\/uploads\/2019\/03\/pia22932-100x300.png 100w\" sizes=\"(max-width: 320px) 100vw, 320px\" \/><\/figure><\/div>\n\n\n\n<p style=\"text-align:left\">Two instruments aboard Juno, the Stellar Reference Unit and JunoCam, \nhave proven to be useful not only for their intended purposes, but also \nfor science data collection. The Stellar Reference Unit (SRU) was \ndesigned to collect engineering data used for navigation and attitude \ndetermination, so the scientists were pleased to find that it has \nscientific uses as well.<\/p>\n\n\n\n<p style=\"text-align:left\">&#171;We always knew the SRU had a vital engineering job to do for Juno,&#187; \nsaid Heidi Becker, Juno&#8217;s radiation monitoring investigation lead at \nNASA&#8217;s Jet Propulsion Laboratory in Pasadena, California. &#171;But after \nmaking scientific discoveries in Jupiter&#8217;s radiation belts and taking a \nfirst-of-its-kind image of Jupiter&#8217;s ring, we realized the added value \nof the data. There is serious scientific interest in what the SRU can \ntell us about Jupiter.&#187;<\/p>\n\n\n\n<p style=\"text-align:left\">The JunoCam imager was conceived as an outreach instrument to bring \nthe excitement and beauty of Jupiter exploration to the public.<\/p>\n\n\n\n<p style=\"text-align:left\">&#171;While originally envisioned solely as an outreach instrument to help\n tell the Juno story, JunoCam has become much more than that,&#187; said \nCandy Hansen, Juno co-investigator at the Planetary Science Institute in\n Tucson, Arizona. &#171;Our time-lapse sequences of images over the poles \nallow us to study the dynamics of Jupiter&#8217;s unique circumpolar cyclones \nand to image high-altitude hazes. We are also using JunoCam to study the\n structure of the Great Red Spot and its interaction with its \nsurroundings.&#187;<\/p>\n\n\n\n<p style=\"text-align:left\">The SRU and JunoCam teams both now have several peer-reviewed science\n papers \u2014 either published or in the works \u2014 to their credit.<\/p>\n\n\n\n<p style=\"text-align:left\">NASA&#8217;s JPL manages the Juno mission for the principal investigator, \nScott Bolton, of the Southwest Research Institute in San Antonio.
