Lava Lakes on Io: Crust Age and Implications for Thermal Output

Alessandro Mura, R. M. C. Lopes, F. Tosi, Peter J. Mouginis-Mark et autres

Abstract Recent observations by the JIRAM instrument on board NASA’s Juno spacecraft have confirmed that many of Io’s volcanic hotspots are active lava lakes, characterized by a colder central crust surrounded by a hotter peripheral ring. In this study, we investigate the …

Lava Lakes on Io: crust age and implications for thermal output

Alessandro Mura, Rosaly Lopes, Jani Radebaugh, Peter J. Mouginis-Mark et autres

Recent observations by NASA’s Juno mission have revealedthat many of Io’s volcanic hot spots are in fact lava lakes,characterized by a colder central crust surrounded by a hotterperipheral ring. In this study, we investigate the thermal propertiesof about twenty such lava lakes, …

Terrestrial Analogs to Titan for Geophysical Research

Conor A. Nixon, Samuel Birch, Audrey Chatain, Charles Cockell et autres

Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas - methane - replacing the Earth's water, …

Active Lava Flows on Io Observed by the JIRAM instrument on Juno

R. M. C. Lopes, A. Mura, Peter J. Mouginis-Mark, Jani Radebaugh et autres

We use data from the Jovian InfraRed Auroral Mapper (JIRAM) instrument on the Juno spacecraft, acquired during close fly-bys of Jupiter's moon Io during 2022-2025 to identify new characteristics of active lava flows. This time period includes observations of an unprecedented large …

Observations of Io from Juno's close flybys

A. Mura, Francesca Zambon, F. Tosi, R. M. C. Lopes et autres

JIRAM (Jovian Infrared Auroral Mapper) is an imager/spectrometeronboard Juno, primarily designed for studying Jupiter's atmosphere andauroral emissions. During its mission, JIRAM also obtained extensivedata on Io, the most volcanically active body in the solar system. Theinstrument combines imaging and spectroscopy in a …

Observations of Loki Patera by Juno during Close Flybys

A. Mura, R. M. C. Lopes, F. Tosi, Francesca Zambon et autres

Abstract We used data from the Juno spacecraft to investigate both the spatial and temporal properties of Loki Patera on Io, acquired in two infrared bands between 2022 December and 2024 April, at pixel sizes ranging from 400 m to 15 km. …

Widespread occurrence of lava lakes on Io observed from Juno

A. Mura, F. Tosi, Francesca Zambon, R. M. C. Lopes et autres

We report recent observations of lava lakes within patera on Io made by the JIRAM imager/spectrometer on board the Juno spacecraft, taken during close observation occurred in the extended mission. At least 40 lava lakes have been identified from JIRAM observations. The …
