Juno to Perform Final Flyby of Io, Heading into Perijove 58 and Reducing Orbital Period

On February 3, Jupiter explorer Juno is planning its 58th flyby of the great gas giant in its extended mission phase. Before the Jupiter flyby, Juno will come within 1,500 km of moon Io—the 4th largest moon and most geologically-active object in the Solar System with 400+ volcanoes. This is the last planned flyby of any one of Jupiter’s 95 moons that are officially recognized by the International Astronomical Union. Since its orbital insertion around the Jovian world on 4 July 2016, Juno has previously flown by Europa once, Ganymede twice, and Io thrice. Some of the data collected from Io observations may help reveal how its volcanic eruptions interact with Jupiter and aurorae, as well as map lava flows and investigate Io gravity field / internal structure. Perijove 58 will also reduce Juno’s orbital period around Jupiter from about 38 days to 33 days. Juno’s extended mission allows the spacecraft to continue operations into September 2025 with perijove 76 which will plunge the orbiter into the cloud tops. ESA Jupiter Icy Moons Explorer (JUICE) mission, launched April 2023, is planned to reach orbital insertion at Jupiter in July 2031, before moving to Ganymede insertion in 2034. NASA Europa Clipper mission is slated to launch this October and arrive, before JUICE, to Jupiter orbit in April 2030. (Image Credits: NASA, JPL-Caltech, SwRI)

DoD contractors participating include Astroscale, Axiom, Blue Origin, Boeing, Lockheed Martin, Northrop Grumman, Sierra, Redwire and Voyager. Recommended dress code for this event is Operational Camouflage Patterns (OCP). Meanwhile, Space Congress organized by Canaveral Council of Technical Societies (CCTS) will commence on Jan 30, as will the SpaceCom Expo. 127 companies and organizations will show off their latest technologies and operational capabilities including Astrobotic, NASA, Orbit Fab and Paragon Space Development in the exhibit hall. Notable conference speakers include ULA CEO Tory Bruno, NASA KSC Strategy & Partnerships Manager Suzy Cunningham, SpaceCom Executive Director Ryan Brown and NASA Deputy Associate Administrator Casey Swails. Artemis 1 Lessons Learned, Commercial Launch Weather Solutions, Propulsion Enabling On-Orbit Servicing, Cutting Edge Technologies and Orbital Transfer Vehicles are among planned topics of moderated panel discussions.
