Juno is nearing the end of its objective in 2025. One of the risks thats bringing its end is Jupiters intense radiation. The spacecrafts orbits are developed to protect it from Jupiters radiation, except when it approaches the world for closer appearances. It needs to remove itself from the extreme radiation to both extend the life of its electronic devices and enable it to send out data back to Earth.
Juno was designed to withstand just 17 orbits of Jupiter but has up until now survived 57. With a couple of more to come, the mission still has lots to teach us about Io and the Jovian system. No doubt well be talented more stunning images and science as it completes its objective.
” Io is only one of the celestial bodies which continue to come under Junos microscope throughout this extended mission,” said Junos acting project manager, Matthew Johnson of NASAs Jet Propulsion Laboratory in Southern California. “As well as constantly altering our orbit to enable brand-new viewpoints of Jupiter and flying low over the nightside of the world, the spacecraft will likewise be threading the needle between a few of Jupiters rings to find out more about their origin and structure.”
Ios primary mission ended in July 2021, and its existing prolonged mission will end in September 2025. At that time, the spacecraft will be sent plunging to its damage in Jupiters atmosphere, ending its nine-year objective.
However these pictures of Io will always become part of its tradition.

NASAs Juno spacecraft has been getting closer and closer to Jupiters volcanic moon Io with each current orbit. Juno is in its 57th orbit of Jupiter, and on December 30th, Juno came to within 1500 km (930 miles) of Ios surface area. Juno is a different spacecraft with more modern-day instruments and video cameras that will fly by Io several times. Io remains volcanic to this day because of its eccentric orbit around Jupiter. Jupiters mass squeezes Io, and the squeezing produces heat that drives its volcanoes.
The Galileo spacecraft took a trip over the moons south pole in 2001, pertaining to within 181 km (112 miles.) Galileo showed us a lot about the nature of Ios surface area.
However Juno is a different spacecraft with more contemporary instruments and video cameras that will zip Io multiple times. Among the objectives specific goals is to figure out if Io has a magma ocean or not. And while the spacecrafts suite of clinical instruments can shed light on that concern, Juno likewise carries an effective camera that rides shotgun: Junocam.
2 other imagers were also busy throughout the Io flyby. One is the Jovian Infrared Auroral Mapper (JIRAM), which takes images in infrared.

Due to the fact that NASA makes them offered for anyone to procedure and post, junocam images get the most attention. Junocam caught six different pictures of the volcanic moon, including white and black and colour.

Researchers understand that Io is the most volcanic body in the Solar System by far. They cravings for more detailed understanding of its interior. Junos series of flybys will permit researchers to see its volcanoes in time, which will help cause some brand-new understandings.
” By integrating information from this flyby with our previous observations, the Juno science team is studying how Ios volcanoes differ,” stated Scott Bolton, Junos principal investigator and a scientist at the Southwest Research Institute, in a statement provided before this most recent flyby. “We are searching for how typically they erupt, how brilliant and hot they are, how the shape of the lava flow modifications, and how Ios activity is linked to the flow of charged particles in Jupiters magnetosphere.”
Io stays volcanic to this day because of its eccentric orbit around Jupiter. Jupiters mass squeezes Io, and the squeezing generates heat that drives its volcanoes. The other Galilean moons add to the result. The tidal force is so strong that Ios surface area can fluctuate by as much as 100 meters.
Io is about the same size as Earths Moon, yet its covered in hundreds of active volcanoes. Theres so much volcanic activity on the surface of Io that some lava circulations are hundreds of kilometres long.
Junos next Io flyby will be on February 3rd. Throughout that see, Juno will also approach about 1500 km (930 miles) above Ios surface area.
” With our pair of close flybys in December and February, Juno will examine the source of Ios huge volcanic activity, whether a magma ocean exists underneath its crust, and the importance of tidal forces from Jupiter, which are non-stop squeezing this tortured moon,” stated Bolton.
