Sputnik 3 (Russian: Спутник-3, Satellite 3) was a Soviet satellite launched on 15 May 1958 from Baikonur Cosmodrome by a modified R-7/SS-6 ICBM. The scientific satellite carried a large array of instruments for geophysical research of the upper atmosphere and near space.

May 15, 2018 · Sputnik 3 reentered the Earth’s atmosphere on April 6, 1960. Its telemetry transmitter and scintillation counter, both powered by experimental silicon solar batteries, operated until the end.

Apr 8, 2025 · Sputnik 3 was an automatic scientific laboratory spacecraft. The scientific instrumentation (twelve instruments) provided data on pressure and composition of the upper atmosphere, concentration of charged particles, photons in cosmic rays, heavy nuclei in cosmic rays, magnetic and electrostatic fields, and meteoric particles.

Mar 29, 2025 · Sputnik 3, launched on May 15, 1958, carried 12 instruments to study Earth’s upper atmosphere and space and was also the heaviest satellite to that time, weighing 1,327 kg (2,926 pounds).

Jun 22, 2024 · This article will delve into the whereabouts of Sputnik 3 and provide answers to some frequently asked questions about this iconic spacecraft. After completing an impressive 692 days in orbit, Sputnik 3 reentered the Earth’s atmosphere and burned up on April 6, 1960.

USSR launches Sputnik-3 On May 15, 1958, the USSR launched the Third Artificial Satellite of the Earth. While two previous Soviet orbiters had been propelled into space primarily for political considerations, Sputnik-3, as it became known in the West, was designed to be a …

May 15, 2018 · This time the rocket operated perfectly placing its 1,327 kilogram payload, now called Sputnik 3, into a 230 by 1,880 kilometer orbit inclined 65.2° to the equator. Once in orbit, Sputnik 3 separated from the spent core of its launch vehicle to start its mission.

Sputnik 3's large load of scientific instruments was designed to measure micrometeorites, density of the upper atmosphere, cosmic rays, solar radiation, the presence and effect of high energy particles and the Earth's own radiation environment. . 43 It could have performed a tour de force of scientific research in virgin territory.

Preliminary plans for it were complete by July of 1956, but the construction and testing of the spacecraft and a dozen scientific experiments required almost two years, and so it became …

Soviet Sputnik 3 was launched on May 15, under the International Geophysical Year programme. It is designed to study the upper layers of the atmosphere and cosmic space. It was orbited at an angle of 65 degrees to the equator. Initial reports place its apogee at 1,880 kilometres. It takes 106 minutes to circuit the Earth.
