The spacecraft used its infrared instrument during recent flybys of Jupiter's mammoth moon to create this latest map, which comes out a decade after Juno's launch.

The science team for NASA's Juno spacecraft has produced a new infrared map of the mammoth Jovian moon Ganymede, combining data from three flybys, including its latest approach on July 20. These observations by the spacecraft's Jovian Infrared Auroral Mapper (JIRAM) instrument, which "sees" in infrared light not visible to the human eye, provide new information on Ganymede's icy shell and the composition of the ocean of liquid water beneath.

JIRAM was designed to capture the infrared light emerging from deep inside Jupiter, probing the weather layer down to 30 to 45 miles (50 to 70 kilometers) below Jupiter's cloud tops.

In 2024, a new age of space exploration will begin when NASA sends astronauts to the moon as part of their Artemis mission, a follow-up to the Apollo missions of the 1960s and 1970s.

Some of the biggest questions that scientists hope to explore include determining what resources are found in the moon's soil and how those resources might be used to sustain life.

In a paper published in the journal Science Advances, researchers at the University of Rochester, leading a team of colleagues at seven other institutions, report their findings on a major factor that influences the types of resources that may be found on the moon: whether or not the moon has had a long-lived magnetic shield at any point in its 4.53 billion-year history.

A new technique for processing lunar radar data has allowed scientists to see what lies beneath the surface of the moon in the clearest ever detail.

In a study led by the University of Aberdeen, a team of researchers discovered multiple layers of soil that lie directly beneath an area on the far side of the moon's surface, overturning an existing theory of a single deep layer in the same area.

The area studied was the landing site of the Chang'E-4 spacecraft mission—the first to the far side of the moon.

Analysis of radar data captured by the mission's rover, Yutu-2, had suggested the existence of a single soil layer in the moon's regolith (subsurface). However, the data did not indicate the existence of different layers of soil, which were transparent to electromagnetic waves due to the smooth boundaries between them.

By developing a new method of processing the data captured by Yutu-2, which uses the shape of radar signatures of buried rocks and boulders to infer the properties of surrounding lunar soil and detect previously unseen layers with smooth boundaries, scientists were able to detect four distinct layers of soil, stacked to a depth of 12 meters.
