A Photochemical PHO Network For Hydrogen-dominated Exoplanet Atmospheres
Due to the detection of phosphine PH3 in the Solar System gas giants Jupiter and Saturn, PH3 has long been suggested to be detectable in exosolar substellar atmospheres too. However, […]
Short-Timescale Spatial Variability of Ganymede’s Optical Aurora
Ganymede’s aurora are the product of complex interactions between its intrinsic magnetosphere and the surrounding Jovian plasma environment and can be used to derive both atmospheric composition and density.
A Gigantic Asteroid Impact Shifted The Axis Of Ganymede
Around 4 billion years ago, an asteroid hit the Jupiter moon Ganymede. Now, a Kobe University researcher realized that the Solar System’s biggest moon’s axis has shifted as a result […]
Planetary Radio Interferometry and Doppler Experiment as an Operational Component of the Jupiter Icy Moons Explorer Mission
We present an overview of the operations and engineering interface for Planetary Radio Interferometry and Doppler Experiment (PRIDE) radio astronomy observations as a scientific component of the ESA s Jupiter […]
Astrobiology Fleet Update: Video: Juice’s Lunar-Earth Flyby
On 19–20 August 2024, Juice successfully completed a world-first lunar-Earth flyby, with flight controllers guiding the spacecraft first past the Moon, then past Earth. The gravity of the two changed […]
Astrobiology Fleet Update: Video: Europa Clipper’s Super-Size Solar Arrays
NASA’s Europa Clipper spacecraft recently got outfitted with a set of enormous solar arrays at the agency’s Kennedy Space Center in Florida. Each measuring about 46½ feet (14.2 meters) long […]
Astrobiology Droid Update: Juice Rerouted To Venus After The First lunar-Earth Flyby
ESA’s Jupiter Icy Moons Explorer (Juice) has successfully completed a world-first lunar-Earth flyby, using the gravity of Earth to send it Venus-bound, on a shortcut to Jupiter through the inner […]
Astrobiology Droid Update: ESA Juice Completes Moon Flyby
During the first step of humankind’s first-ever lunar-Earth flyby, ESA’s Jupiter Icy Moons Explorer (Juice) mission captured this stunning view of the Moon.
Comparing NASA Discovery and New Frontiers Class Mission Concepts for the Io Volcano Observer (IVO)
Jupiter’s moon Io is a highly compelling target for future exploration that offers critical insight into tidal dissipation processes and the geology of high heat flux worlds, including primitive planetary […]
