Impact-induced Contamination of Ganymede’s Deep Ice Shell
The Planetary Science JournalJuno flew by Ganymede in 2021 June and measured the microwave brightness temperatures of the ice shell at six frequencies from 0.6–22 GHz. Based on the increasing brightness temperature with wavelength, S. Brown et al.

Planet Mass Function around M Stars at 1–10 au: A Plethora of Sub-Earth Mass Objects
The Astrophysical JournalSmall planets (≲1 M _⊕ ) at intermediate orbital distances (∼1 au) represent an uncharted territory in exoplanetary science. The upcoming microlensing survey by the Nancy Grace Roman Space Telescope will be sensitive to objects as light as Ganymede and ...

Far-infrared photometric observations of the outer planets and satellites with Herschel-PACS
, 2016 We present all Herschel PACS photometer observations of Mars, Saturn, Uranus, Neptune, Callisto, Ganymede, and Titan. All measurements were carefully inspected for quality problems, were reduced in a (semi-)standard way, and were calibrated.

The dynamics of the de Sitter resonance
, 2017 We study the dynamics of the de Sitter resonance, namely the stable equilibrium configuration of the first three Galilean satellites. We clarify the relation between this family of configurations and the more general Laplace resonant states.

Resonant Plasma Acceleration at Jupiter Driven by Satellite‐Magnetosphere Interactions
Geophysical Research LettersThe Juno spacecraft had previously observed intense high frequency wave emission, broadband electron and energetic proton energy distributions within magnetic flux tubes connected to Io, Europa, Ganymede, and their wakes.

Coordinates of features on the Galilean satellites [PDF]
Control nets of the four Galilean satellites, established photogrammetrically from pictures taken by the two Voyager spacecraft during their flybys of Jupiter in 1979, are discussed.

Ejecta types on Ganymede and Callisto [PDF]
Ejecta types on Ganymede and Callisto have been identified from Voyager 1 and 2 images. Image resolution used range from approx. 0.6 to approx. 4 km/pxl, which allowed the surveying of almost all of the mappable surface of the two satellites.

A Billion-Year Facelift and Cleaner Air
The Scientific World Journal, 2001 Science leads the first (or is it second?) year of the millennium with a story about a facelift for Jupiter’s moon, Ganymede. Nature leads with a story about new regulations on diesel-powered vehicles in the U.S.

Geologic investigations of outer planets satellites [PDF]
Four tests are examined: (1) investigation of volcanism on Io; Interim results of thermal and structural modeling of volcanism on Io are presented, (2) a study of the ancient heavily cratered regions on Ganymede, (3) a geologic comparison of the ...

Europa, Another Water Moon? [PDF]
, 1999 Comparing Europa to Earth's size and oceans, this resource tells the story of the Galileo spacecraft's exploration of Europa in the late 1990's, and explains why scientists believe there may be an ocean of water underneath Europa's icy crust. Educational
