• November 3 – Mariner program: NASA launches the Mariner 10 toward Mercury (on March 29, 1974, it becomes the first space probe to reach that planet); it will be the first space flight to use gravity assist.
• December 3 – Pioneer program: Pioneer 10 sends back the first close-up images of Jupiter.
• December 7 – The "Big Ear" at the Ohio State University Radio Observatory begins a full-time search for extraterrestrial intelligence (SETI) radio survey, running continuously until 1995.

Biology

Computer science

• March 1 - Xerox PARC releases the Xerox Alto. The first computer designed to support an operating system based on a graphical user interface.
• September - The TV Typewriter appears on the cover of Radio-Electronics. Designed by Don Lancaster, it was a video terminal that could display two pages of 16 lines of 32 upper case characters on a standard television set.
