Launched on April 14, 2023, the European Space Agency’s (ESA) Jupiter Icy Moons Explorer (Juice; formerly known as JUICE) spacecraft has finally completed the unfurling of its solar panel arrays and plethora of booms, probes, and antennae while en route to the solar system’s largest planet.Continue reading “Juice is Fully Deployed. It’s Now in its Final Form, Ready to Meet Jupiter’s Moons in 2031”
The European Space Agency’s (ESA) recently launched Jupiter Icy Moons Explorer (JUICE) mission and NASA’s upcoming Europa Clipper mission could allow scientists to image landslides on the icy moons of Europa and Ganymede due to potential moonquakes on these small worlds. This comes after a recent study examined fault scarps on Europa and Ganymede orbiting Jupiter and Enceladus and Dione orbiting Saturn with the goal of drawing a connection between tectonic activity (quakes) and observed mass wasting (landslides) on these surfaces. The researchers “consider whether such smooth material can be generated by mass wasting triggered from local seismic shaking”, according to the study.Continue reading “We Could Soon See Landslides on Europa and Ganymede”
As the European Space Agency’s Juice spacecraft headed out on an eight-year trip to Jupiter’s icy moons, it turned back to snap some selfies with Earth in the background — and those awesome shots are just the start.
The bus-sized probe is due to make four slingshot flybys of Earth and Venus to pick up some gravity-assisted boosts to its destination — and ESA mission managers plan to have the monitoring cameras running during those close encounters.Continue reading “Juice Looks Back at Earth During Its Space Odyssey to Jupiter’s Moons”
A new era of exploration at Jupiter’s moons began last week with the launch of the European Space Agency’s Juice, the Jupiter Icy Moons Explorer. This mission will visit three of Jupiter’s largest moons — Europa, Callisto and Ganymede — to investigate whether they could be potentially habitable, a question that’s been highly debated since the first evidence of subsurface oceans on these moons was seen by the Galileo mission in the 1990s.Continue reading “ESA's Juice is On Its Way to Visit Jupiter's Moons”
Now less than one year until the projected launch date, ESA’s JUICE mission is in the final phases of development. The JUpiter ICy moons Explorer (JUICE) is now fully built with all ten instruments integrated into the spacecraft bus. Next comes all-up testing in a full flight configuration.
Launch is currently scheduled for April of 2023, with the mission slated to conduct detailed investigations of Jupiter and its system of moons, focusing on Europa, Callisto and especially Ganymede.Continue reading “ESA's Juice Mission is Fully Integrated and Ready for Testing. Soon it'll fly to Space on a Mission to Jupiter's Moons”
Are we alone? Is there life beyond Earth? These are the questions that plague the very essence of science, and in particular, planetary science. Unfortunately, robotic exploration of exoplanetary systems currently remains out of reach due to the literal astronomical distances to get there. For context, our nearest star, Proxima Centauri, is 4.25 light years away, or a mind-blowing 40,208,000,000,000 km (25,000,000,000,000 miles) from Earth. Finding an intelligent civilization might be out of reach for now but searching for any forms of life beyond Earth is very much possible within the confines of our own solar system.Continue reading “What’s the Right Depth to Search for Life on Icy Worlds?”
This week we are aired Fraser’s pre-recorded interview with Dr. Olivier Witasse, Project Scientist on the JUICE mission.Continue reading “Weekly Space Hangout: November 25, 2020, Dr. Olivier Witasse, Project Scientist, the JUICE Mission”
Earlier this week, we shared some stunning, newly reprocessed images of Europa from NASA’s Galileo spacecraft, which visited Jupiter and its moons from December 1995 to September 2003. Now, as scientists continue to revisit Galileo’s data, even more details are coming into focus about Jupiter’s enticing moon. Not only is there evidence within the past few years of geysers shooting from Europa’s surface, twenty years ago, Galileo may have also witnessed a cryovolcanic eruptions — or plumes of water — spewing from the icy moon.Continue reading “Even More Evidence that Europa has Geysers”
