This unprocessed image shows the successful “first light” for Europa Clipper’s MISE instrument. The image was produced by directing an artificial light source into the instrument’s entry slit. The white line shows the spectrum of a small light spot, simulating a small area on Europa. The blue background is the low-light background of the instrument’s test setup.
