The Mariner 2 probe at an assembly facility in Cape Canaveral, Fla., on Aug. 29, 1962.
Radio signals from the Mariner spacecraft were received on three 85-foot antennas like this one, which were built in California's Mojave desert, near Johannesburg in South Africa, and near Woomera in southern Australia.
In the California receiver control room, personnel await confirmation that Mariner has begun to scan the planet Venus.
Data from the receivers were teletyped in a coded format to the Jet Propulsion Laboratory in California.
There, the data was routed to the digital computer at JPL.
Printouts of the data were made available to the experimenters.
At the operations center at JPL, the spacecraft's status was posted on the wall.
A model of JPL's Mariner 2 spacecraft above a floral "Venus" moved down Colorado Boulevard in Pasadena, Calif., in the 1963 Tournament of Roses Parade on Jan. 1.
Scientists show off reams of data collected by Mariner 2 as it passed by Venus. The probe flew by the planet on Dec. 14, 1962, and scanned the surface for 42 minutes.

These days, vivid photographs showing scenes from all around the solar system are so ubiquitous that people might easily forget how mysterious our planetary neighbors used to be.
The world mourned the death this week of Indian maestro Ravi Shankar, whose name became synonymous with the sitar. Tributes eulogized Shankar as the great connector of the East and West who'd hobnobbed with The Beatles and collaborated with violin virtuoso Yehudi Menuhin. Less has been said about the roots of the music he spent a lifetime perfecting and innovating.

Japanese nationalists condemn China at a rally in Tokyo in September. Japan and China are locked in a bitter dispute over a group of islands claimed by both countries.
The Statue of Liberty still lifts her lamp beside the golden door, but the island that's home to the iconic statue was severely tempest-tost by Superstorm Sandy. Flood damage inflicted by the storm has closed Liberty Island and nearby Ellis Island indefinitely.

And the year's not over yet.
On Sunday, Messi, 25, scored his 86th goal of the calendar year in a Spanish league game against Real Betis, in Seville. The goal, Messi's second of the game, gave Barcelona a 2-1 win over Betis, with the announcer booming, "A new goal king!"
