The Sputnik 1 satellite was a 585 mm (23 in) diameter sphere, made of highly polished 2 mm-thick aluminum AMG6T alloy,[13] carrying four whip-like antennas between 2.4 and 2.9 meters (7.9 and 9.5 ft) in length. The antennas resembled long "whiskers" pointing to one side. It had two radio transmitters (20.005 and 40.002 MHz) and is believed to have orbited Earth at a height of about 250 km (150 mi). Analysis of the radio signals was used to gather information about the electron density of the ionosphere. Temperature and pressure were encoded in the duration of radio beeps, which additionally indicated that the satellite had not been punctured by a meteorite. Sputnik 1 was launched by an R-7 rocket. It burned up upon re-entry on January 4, 1958.
