Apollo 9 lifts off on a ten-day mission to test the first lunar lander, but only in Earth orbit. Jim McDivitt and Rusty Schweickart put the lunar module, nicknamed Spider, through its paces, while David Scott mans the command module Gumdrop. This is the first flight of the completely non-aerodynamic lunar module, and various docking maneuvers and spacewalk scenarios are practiced. The crew returns to Earth in the Apollo command module, while Spider is left in a low orbit which decays two weeks later, allowing it to disintegrate in Earth’s atmosphere.
This mission is dramatized in the Spider episode of HBO’s 1998 series From The Earth To The Moon.

This is the observed day of the internet’s birth, actually marking the day that the Defense Advanced Research Projects Agency chose the contractor to build the initial nodes and connections of the ARPAnet. Though the internet is ubiquitous from a 21st century perspective, its origins lie in a disquieting Cold-War-era concept of a distributed computer communications network whose operations could continue even if multiple nodes of the network have been disrupted or destroyed. ARPAnet, the forerunner to the modern internet, will become operational on an experimental basis later in 1969.

NASA launches the Nimbus 3 satellite, designed to observe weather patterns from orbit and test new weather and climate detection technologies. Nimbus 3 is the first Earth-orbiting spacecraft to test the SNAP-19 radioisotope thermoelectric generator system; devices similar to the SNAP-19 will become the primary power source for later deep space and outer solar system interplanetary missions. Nimbus 3 loses attitude control in 1970, but is kept online for engineering information-gathering purposes until 1972.
