NASA dusts off FORTRAN manual, revives 20-year-old data on Ganymede

NASA scientists have made some new discoveries about Jupiter’s giant moon Ganymede, thanks to a dedicated team, an elderly VAX machine and 20-year-old data from the long-defunct Galileo probe.

Fifteen years after Galileo (no, not that one) ended its days with a plunge into the atmosphere of Jupiter, NASA scientists have resurrected the 20-year-old datasets and added more detail to the puzzle of Ganymede’s magnetosphere.

The new data, published in Geophysical Research Letters, paints a picture of a stormy environment, with particles blasted off the moon’s icy surface by incoming plasma raining down from Jupiter.

Data from Galileo’s Plasma Subsystem (PLS), which measured the direction, density and temperature of the plasma, also showed an explosive magnetic event occurring between Jupiter and Ganymede’s magnetic environments.
