On New Years Day 1963, a model of JPL's Mariner 2 spacecraft above a floral "Venus" moved down Colorado Boulevard in the annual Tournament of Roses Parade. JPL Director William Pickering, Grand Marshal of the
parade, rode just ahead of the float, which was built and funded by JPL volunteers.
Launched on August 27, 1962, Mariner 2 was one of two spacecraft designed and built by JPL to fly by Venus. Mariner 2 was the first spacecraft to observe another planet, returning 42 minutes of data about the atmosphere and surface of the planet before going into heliocentric orbit. It was one of a series of Mariner missions designed to explore Earth's nearest neighbors, Venus and Mars.
