Sputnik 22
Mars 2MV-4 No.1 also known as Sputnik 22 in the West, was a Soviet spacecraft, which was launched in 1962 as part of the Mars programme, and was intended to make a flyby of Mars, and transmit images of the planet back to Earth. Due to a problem with the rocket which launched it, it was destroyed in low Earth orbit. It was the first of two Mars 2MV-4 spacecraft to be launched, the other being the Mars 1 spacecraft which was launched eight days later. Launch With the Cuban Missile Crisis unfolding, the USSR spacecraft ''Mars 2MV-4 No.1'' was launched at 17:55:04 UTC on 24 October 1962, atop a Molniya 8K78 carrier rocket flying from Site 1/5 at the Baikonur Cosmodrome. The lower stages of the rocket performed nominally, placing the payload and the Blok L upper stage into low Earth orbit. When the Blok L ignited following a coast phase, lubricant leaked out of the turbopump, which consequently seized up and disintegrated. This caused the main engine to explode, destroying the upp ...

Mars
Mars is the fourth planet from the Sun. It is also known as the "Red Planet", because of its orange-red appearance. Mars is a desert-like rocky planet with a tenuous carbon dioxide () atmosphere. At the average surface level the atmospheric pressure is a few thousandths of Earth's, atmospheric temperature ranges from and cosmic radiation is high. Mars retains some water, in the ground as well as thinly in the atmosphere, forming cirrus clouds, frost, larger polar regions of permafrost and ice caps (with seasonal snow), but no liquid surface water. Its surface gravity is roughly a third of Earth's or double that of the Moon. It is half as wide as Earth or twice the Moon, with a diameter of , and has a surface area the size of all the dry land of Earth. Fine dust is prevalent across the surface and the atmosphere, being picked up and spread at the low Martian gravity even by the weak wind of the tenuous atmosphere. The terrain of Mars roughly follows a north-south ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Space Command
The Naval Space Command (NSC) was a military Command (military formation), command of the United States Navy and former component command of United States Space Command. It was headquartered at Dahlgren, Virginia, and began operations on 1 October 1985. Naval Space Command used space capabilities to support naval forces through the operation of reconnaissance satellites, reconnaissance and communications satellites, as well as representing the Navy's space interests, both within the Navy and within U.S. Space Command. The command was merged into Naval Network and Space Operations Command, itself part of Naval Network Warfare Command, about July 2002. History In the late 1950s the United States Naval Research Laboratory's Project Vanguard Minitrack system used electronic signals emitted by Sputnik and other satellites to characterize their orbits, serving as one of the first methods of ground-based satellite tracking. This system would become commissioned in 1961 as the Naval Spa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
