After entering safe mode last week during its Earth flyby, Juno returned to normal operations and downlinked all engineering and science instrument data. It entered safe mode again on Sunday night, but it is expected to re-resume normal operations late next week.

I try to be measured in my praise for spacecraft images. Not every photo can be the greatest space image ever. But this enormous mosaic showing the flattened globe of Saturn floating within the complete disk of its rings must surely be counted among the great images of the Cassini mission.

Bruce Murray was an early advocate for the inclusion of cameras on planetary spacecraft. As a tribute to him, I thought I'd take a look at a few of the images from the early Mariner missions to Mars.
