PIA00845: NIMS: hotspots on Io during G2 (continued)

NIMS: hotspots on Io during G2 (continued)


This is another Near Infrared Mapping Spectrometer (NIMS) image of Io, taken during the G2 encounter in September 1996. This is a dayside image of Io (on the right) against the clouds of Jupiter (the blue background). On the left is a Voyager mosaic of Io with the same viewing geometry for comparison purposes. This NIMS data set has been processed to highlight the positions of hot spots on the surface of Io. At least 11 can be seen. Two of the hotspots are newly discovered by the NIMS instrument. Others correspond to sites of plume eruptions and volcanic calderas and volcanic flows. This image can be compared with the SSI image P-47971 released on October 23, 1996, which was taken almost exactly the same position.
