Juno data provides insight into thickness of Europa’s surface ice sheet
Using recent data from NASA’s Juno orbiter, scientists have uncovered new details on the thickness and structure of Europa’s surface ice shell, which encases the Jovian moon’s subsurface ocean. For planetary scientists and astrobiologists, Europa’s ocean makes the moon one of the most likely places for life to exist outside of Earth. Since entering orbit…

Juno reveals Io’s inner structure and volcanic activity; investigates north pole cyclones
New data from NASA’s Juno mission, which has been orbiting Jupiter since 2016, has provided scientists with insight into the extreme winds and cyclones present within the gas giant’s atmosphere. The data allowed scientists to develop a model that better represents the fast jet stream circling Jupiter’s north pole, which is cluttered with many cyclones.…

Over a month into mission, Europa Clipper continues deploying instruments
On Oct. 14, NASA’s groundbreaking Europa Clipper mission launched from Launch Complex 39A at the Kennedy Space Center in Florida atop a SpaceX Falcon Heavy rocket. Falcon Heavy’s 27 Merlin engines and single vacuum-optimized Merlin engine sent Europa Clipper on a trajectory out of the Earth-Moon system at a speed of approximately 35 km/s relative…

NASA launches mission to explore the frozen frontier of Jupiter’s moon Europa
NASA’s Europa Clipper spacecraft lifted off Monday from Kennedy Space Center in Florida aboard a SpaceX Falcon Heavy rocket, kicking off a $5.2 billion robotic mission to explore one of the most promising locations in the Solar System for finding extraterrestrial life. The Falcon Heavy rocket fired its 27 kerosene-fueled engines and vaulted away from…

NASA, SpaceX launch historic Europa Clipper mission to Jupiter
NASA and SpaceX have launched NASA’s Europa Clipper mission to Jupiter’s icy moon Europa atop a SpaceX Falcon Heavy rocket. Falcon Heavy launched during an instantaneous launch window on Monday, Oct. 14, at 12:05 PM EDT (16:05 UTC) from Launch Complex 39A (LC-39A) at the Kennedy Space Center in Cape Canaveral, Florida. If Monday’s attempt…

NASA will proceed with final preps to launch Europa Clipper next month
For a while earlier this summer, it looked like NASA’s flagship mission to study Jupiter’s icy moon Europa might miss its launch window this year. In May, engineers raised concerns that transistors installed throughout the spacecraft might be susceptible to damage from radiation, an omnipresent threat for any probe whipping its way around Jupiter. The…

Webb finds never-before-seen structures above Jupiter’s Great Red Spot
Using the joint NASA, European Space Agency (ESA), and Canadian Space Agency (CSA) James Webb Space Telescope, a group of scientists has discovered a variety of never-before-seen features in Jupiter’s upper atmosphere. The features were found in the atmospheric region above the iconic Great Red Spot—a high-pressure region in Jupiter’s atmosphere that produces a massive…

Juno observes lava lake on Io, provides insight into Jupiter’s water abundance
In December 2023 and February 2024, NASA’s Juno spacecraft, currently in orbit around and investigating Jupiter and the Jovian system, made several close flybys of the innermost of the Galilean moons, Io. During the flybys, Juno came as close as 1,500 kilometers from the surface of Io, during which extensive data and imagery of the…

As Europa Clipper nears October launch date, scientists anticipate groundbreaking results
Later this year, a SpaceX Falcon Heavy rocket will launch from Launch Complex 39A at the Kennedy Space Center with one of the most highly-anticipated and monumental planetary science missions of the decade — Europa Clipper. The mission will see the spacecraft travel to the smallest of Jupiter’s four Galilean moons, Europa, to investigate the…

Juno measures oxygen production on Europa
Using NASA’s Juno spacecraft, scientists have calculated the rate of oxygen production on Jupiter’s moon Europa — the first time any spacecraft had directly measured charged oxygen and hydrogen particles from the moon’s atmosphere. From these measurements, the team determined the rate of oxygen production to be much lower than estimated in previous studies. Europa,…
