Ten days after a bomb went off at his prayer meeting, Nathuram Godse, a Hindu nationalist, stepped out of the crowd as Gandhi walked to prayers at about 5.17 pm and shot him three times at close range.

A bomb exploded on the porch of the parsonage while King was speaking at a mass meeting. His wife Coretta and their baby daughter were inside and unhurt. King calmed the armed crowd that gathered outside and asked them to go home without violence.

Units in the Central Highlands and on the central coast attacked Nha Trang, Ban Mê Thuột, Kontum, Pleiku and other towns a night early, giving the South a day’s warning. One explanation offered: in 1967 the North moved its clocks to UTC+7, and its Tết fell a day earlier than the South’s.

During the lunar new-year truce 77,000 to 84,000 communist troops, by different counts, attacked cities across the South: 36 of the 44 provincial capitals, five of the six autonomous cities, and Saigon itself. Hanoi hoped for a general uprising; none came, and the Viet Cong lost much of its…

About 13:04, as the second “Don’t Let Me Down” began. The band had rather hoped to be dragged off on camera; instead the constables asked for the volume down.

About 13:08, in the last “Get Back”. At the police’s request Mal Evans switched off Harrison’s and Lennon’s amplifiers; Harrison switched his back on, Evans relented, and McCartney ad-libbed about playing on the roofs again and being arrested.

Venus and Halley in one trip, with instruments from across Europe. At Venus in June 1985 it dropped a lander and a balloon that drifted for two days in the clouds, tracked by radio telescopes around the world.

Four telescopes for four kinds of light: Hubble, Compton for gamma rays (1991), Chandra for X-rays (1999) and Spitzer for infrared (2003). They never all flew at once: Compton was brought down on purpose in June 2000 after a gyroscope failed, three years before Spitzer launched.
