It's one small sign of how long I've managed to keep posting things to this journal, and a small illustration of how history keys together too, that I've managed to get from the fortieth anniversary of Apollo 11 landing on the Moon to the fortieth anniversary of Viking 1 landing on Mars. The two are linked on the calendar even if by accident; Viking 1 had been meant to land on the American Bicentennial, but its intended landing site had wound up looking too rough to the improved cameras of its orbiter. When it did make it to the surface, though, it pretty much set expectations; I was surprised and somehow invigorated when Mars Pathfinder had seen more prominent hills on the horizon two decades later, and surprised again whenever another rover doesn't find the sand at its landing site as littered with rocks as the Vikings did. At the same time, though, I did spend at least a bit of today remembering the Soviet probes that had reached the surface before the Vikings, even if the longest-lived of them only sent back a few seconds' worth of an indecipherable picture before it gave out in the dust storm it had managed to touch down in.
