Two copies of Porter's script for 'The Night Sky in September' on Mars near the Pleiades and the Hyades close to Aldebaran at its stationary point on 9 October; its retrograde motion south of the ecliptic in an orbit tilted with respect to that of the Earth; the orbit of the Moon also swinging round in space so that occultations of Aldebaran will occur in 1959 and 1960, but in 9 or 10 years will be occulting the Pleiades; the orbit being elliptical so that the Moon appears larger or smaller depending on its distance, a distance which varies by 30,000 miles; the phases of the Moon occurring at varying intervals due to the inconstancy of its speed, its very complex motion and Newton's comment; the evection of the Moon discovered by Hipparchus, Tycho Brahe discovering other small variations in the Moon's motion, and the 150 periodic terms which we now take into account with hundreds of smaller terms; the captured rotation and libration meaning that 41% of the Moon is never seen from the Earth; and the chances of success of the projected rocket viewing this hidden side of the Moon reckoned to be worse than 1 in 10.
