Félicette
Félicette () was a Parisian cat that became the first feline launched into space on 18October 1963 as part of the French space program. She was one of 14 female cats trained for spaceflight. The cats had electrodes implanted into their skulls to monitor their neurological activity throughout the flight. During the flight, electrical impulses were applied to the brain and a leg to stimulate responses. The capsule was recovered 13 minutes after the rocket was ignited. Most of the data from the mission was of good quality, and Félicette survived the flight but was euthanised two months later

Syncom
thumb|Artist's vision of Syncom satellite, 1963
Syncom (for "synchronous communication satellite") started as a 1961 NASA program for active geosynchronous communication satellites, all of which were developed and manufactured by the Space and Communications division of Hughes Aircraft Company (now the Boeing Satellite Development Center). Syncom 2, launched in 1963, was the world's first geosynchronous communications satellite. Syncom 3, launched in 1964, was the world's first geostationary satellite.

Thor-Agena
Thor-Agena was a series of orbital launch vehicles. The launch vehicles used the Douglas-built Thor first stage and the Lockheed-built Agena second stages. They are thus cousins of the more-famous Thor-Deltas, which founded the Delta rocket family.
