Trashing the TARDIS

Doctor WhoThe BBC archives erase dozens more episodes of Doctor Who due to an ongoing space crunch and an impending change of video standard from 405-line PAL to 625-line PAL. Whereas the first round of tape-wiping in 1967 was targeted at episodes involving the first Doctor, this round marks episodes featuring the current Doctor, Patrick Troughton, for deletion. The fourth episode of The Tenth Planet – Hartnell’s swan song in the role of the Doctor – is erased at this time, as well as a curious scattershot selection of Troughton episodes.

Mercury 2: canned Ham

HamThe first living creature to reach space aboard an American rocket is Ham, a chimpanzee wired with electrodes and sensors to determine the effects of space travel on a higher primate whose body might react similarly to that of a human being. NASA sends Ham on the sixteen-minute suborbital Mercury 2 flight, ending in a splashdown in the Atlantic. Both Ham and his vehicle survive the flight despite numerous equipment glitches in both the Redstone rocket and the Mercury capsule itself (which actually blasts away from the Redstone via its launch abort system), which loses cabin pressure (fortunately, Ham has his own spacesuit to protect him) and then puts its primate pilot through a punishing 17G reentry. For his pioneering feat of spaceflight, Ham receives an apple, an orange, and paid retirement to the National Zoo.

Explorer 1

Explorer 1The United States succeeds in launching its own artificial satellite, Explorer 1, atop a Juno 1 rocket. Instruments developed by Dr. James Van Allen reveal the existence of radiation surrounding the Earth, and the areas of radiation are subsequently named the Van Allen radiation belts. The satellite itself is designed by the Jet Propulsion Laboratory and remains in orbit until 1970 – just the first hint of JPL’s knack for making spacecraft that last longer than their rated lifespans.
