"Sputnik 1" ( _ru. "Спутник-1" IPA-ru|ˈsputnʲɪk, "Satellite-1", ПС-1 ("PS-1", i.e. "Простейший Спутник-1", or "Elementary Satellite-1")) was the world's first Earth-orbiting artificial
satellite. Launched into geocentric orbitby the Soviet Unionon October 4, 1957, it was the first in a series of satellites collectively known as the Sputnik program. The unanticipated announcement of "Sputnik 1"'s success precipitated the Sputnik crisisin the United Statesand ignited the Space Racewithin the Cold War.
"Sputnik" helped to identify the upper atmospheric layer's density, through measuring the satellite's orbital changes. It also provided data on
radio-signal distribution in the ionosphere. Pressurized nitrogen, in the satellite's body, provided the first opportunity for meteoroiddetection. If a meteoroid penetrated the satellite's outer hull, it would be detected by the temperature data sent back to Earth.
"Sputnik-1" was launched during the
International Geophysical Yearfrom Site No.1, at the 5th Tyuratamrange, in Kazakh SSR(now at the Baikonur Cosmodrome). The satellite traveled at 29,000 kilometres (18,000 mi) per hour and emitted radio signals at 20.005 and 40.002 MHz[cite news

Before the launch
atellite construction project
The history of the "Sputnik 1" project dates back to May 27, 1954, when
Sergei Korolevaddressed Dmitry Ustinov, then Minister of Defense Industries, proposing the development of an Earth-orbiting artificial satellite. Korolev also forwarded Ustinov a report by test launches – held a meeting where Korolev presented calculation data for a spaceflight tragectory to the Moon. They decided to develop a three-stage version of the R-7 rocket for satellite launches. [cite web | url=http://epizodsspace.testpilot.ru/bibl/vetrov/korolev-delo/06-01.html | title=G. S.

On January 30, 1956, the
Council of Ministers of the USSRapproved practical work on an artificial Earth-orbiting satellite. This satellite, named "Object D", was planned to be completed in 1957-58; it would have a mass of 1,000 to 1,400 kg (2,200 to 3,090 lb) and would carry 200 to 300 kg (440 to 660 lb.) of scientific instruments.

* Ministry of Defense was responsible for conducting launches
By July 1956 the draft was completed and the scientific tasks to be carried out by a satellite were defined. It included measuring density of the atmosphere, its
ioncomposition, corpuscular solar radiation, magnetic fields, cosmic rays, etc. Data valuable for creating future oriented satellites was also planned to be collected. A ground observational complex was developed, that would collect information transmitted by the satellite, observe the satellite's orbit, and transmit commands to the satellite. Such a complex should include up to 15 measurement stations. Due to the limited time frame, they should have means designed for rocket R-7 observations. Observations were planned for only 7 to 10 days and orbit calculations were expected to be not quite accurate. [cite web | url=http://epizodsspace.testpilot.ru/bibl/nk/1997/16/16-1997.html | title=40 Years of Space Era | language=Russian | accessdate=2008-03-26]
Unfortunately, the complexity of the ambitious design and problems in following exact specifications meant that some parts of 'Object D', when delivered for assembly, simply did not fit with the others, causing costly delays. By the end of 1956 it became clear, that plans for 'Object D' were not to be fulfilled in time due to difficulties creating scientific instruments and the low
specific impulseproduced by completed R-7 engines (304 sec instead of the planned 309 to 310 sec). Consequently the government re-scheduled the launch for April 1958. Object D would later fly as Sputnik 3.
Fearing the U.S. would launch a satellite before the USSR, OKB-1 suggested the creation and launch of a satellite in April-May 1957, before the IGY began in July 1957. The new satellite would be simple, light (100 kg), and easy to construct, forgoing the complex, heavy scientific equipment in favour of a simple radio transmitter. On February 15, 1957 the Council of Ministers of the USSR approved this, providing for launching the simplest version satellite, designated 'Object PS'.cite web | url=http://claudelafleur.qc.ca/Spacecrafts-1957.html | title=Spacecrafts launched in 1957 | accessdate=2008-03-26] This version also facilitated the satellite to be visually tracked by Earth-based observers while in orbit, and transmit tracking signals to ground-based receiving stations.cite web | url=http://claudelafleur.qc.ca/Spacecrafts-1957.html | title=Spacecrafts launched in 1957 | accessdate=2008-03-26] Launch of two satellites PS-1 and PS-2 with two R-7 rockets (8K71) was allowed, but only after one or two successful R-7 test launches.
Launch vehicle preparation and launch site selection
R-7 rocketwas initially designed as an ICBMby OKB-1. The decision to build it was made by the CPSU Central Committeeand the Council of Ministers of the USSR on May 20, 1954. [ru icon [http://www.arms.ru/nuclear/R7.htm ICBM R-7] at Arms.ru] A special reconnaissancecommission selected Tyuratam as a place for the construction of a rocket proving ground(the 5th Tyuratam range, usually referred to as "NIIP-5", or "GIK-5" in the post-Soviet time). The selection was approved on February 12, 1955 by the Council of Ministers of the USSR, but the site would not be completed until 1958. [ [http://www.russianspaceweb.com/baikonur_origin.html Origin of the test range in Tyuratam] at Russianspaceweb.com] Actual work on the construction of the site began on July 20 by military building units. On June 14, 1956 Sergei Korolev decided to adapt the R-7 rocket to the 'Object D', [ [http://www.russianspaceweb.com/sputnik3.html Sputnik-3] at Russianspaceweb.com] that would later be replaced by the much lighter 'Object PS'.
The first launch of an R-7 rocket (8K71 No.5L) occurred on May 15, 1957. The flight was controlled until the 98th second, but a fire in a strap-on rocket led to an unintended crash 400 km from the site. [http://www.astronautix.com/lvs/r7.htm R-7] at Astronautix.com] Three attempts to launch the second rocket (8K71 No.6) were made on 10 June-11 June, which failed due to a mistake made during the rocket's assembly.

During the flight the rocket began to rotate about its longitudinal axisand its engines were automatically turned off. The packet of stages was destroyed 32.9 seconds into the flight. The stages fell 7 km from the site and exploded. [http://www.russianspaceweb.com/r7.html R-7 family of launchers and ICBMs] at Russianspaceweb.com]
The launch of the fourth rocket (8K71 No.8), on August 21 at 15:25
Moscow Time, was successful. Its head part separated, reached the defined region, entered the atmosphere, and was destroyed at a height of 10 km due to thermodynamicoverload after traveling 6,000 km. On August 27 TASSthe USSR issued a statement on the launch of a long-distance multistage ICBM. The launch of the fifth R-7 rocket (8K71 No.9), on September 7, was also successful, but the head part was also destroyed in the atmosphere, and hence needed a long redesign to completely fit its military purpose. The rocket, however, was already suitable for scientific satellite launches and this "time-out" of the rocket's military exploitation was used to launch the PS-1 and PS-2 satellites.
On September 22 a modified R-7 rocket, named Sputnik Rocket ( _ru. ракета-носитель Спутник) and indexed as 8K71PS, with the satellite PS-1, arrived at the proving ground and preparations for the launch began.

thrustat the moment of start was 3.90 MN. [ [http://www.russianspaceweb.com/sputnik_lv.html Sputnik launch vehicle 8K71PS] ]
The measurement complex at the proving ground for monitoring launch vehicle parameters from its start onward was completed prior to the first R-7 rocket test launches in December 1956. It consisted of six static stations: IP-1 through IP-6, with IP-1 situated at a distance of 1 km from the launch pad.ru icon [http://www.novosti-kosmonavtiki.ru/content/numbers/237/36.shtml Creation and Launch of the First Earth's Satellite] by V.Poroshkov] The main monitoring devices of these stations were telemetry and trajectory measurement stations, "Tral," developed by
OKBMEI.

The data was useful even after the satellite's separation from the second stage of the rocket; Sputnik's location was calculated from the data on the second stage's location (which followed Sputnik at a known distance) using nomograms developed by P.E. Elyasberg. [ [http://rgantd.ru/book_2.php?link=mozjorin Yu.A.Mozzhorin Memories] at the website of Russian state archive for scientific-technical documentation ]
An additional observational complex, established to track the satellite after its separation from the rocket, was completed by a group led by
ColonelYu.A.Mozzhorin in accordance with the General Staff directive of May 8, 1957. It was called the Command-Measurement Complex and consisted of the coordination center in "NII-4" by the Ministry of Defence of the USSR (at Bolshevo) and seven ground tracking stations, situated along the line of the satellite's ground track. They were: NIP-1 (at Tyuratamstation, Kazakh SSR, situated not far from IP-1), NIP-2 (at Makat station, Guryev Oblast), NIP-3 (at Sary-Shagan station, Dzhezkazgan Oblast), NIP-4 (at Yeniseysk), NIP-5 (at village Iskup, Krasnoyarsk Krai), NIP-6 (at Yelizovo) and NIP-7 (at Klyuchi). [ [http://www.missiles.ru/VPK-missiles-Tikhonov.htm История предприятий, связанных с производством ракетной техники ] ] The complex had a communication channel with the launch pad. Stations were equipped with radar, optical instruments, and communication means. PS-1 was not designed to be controlled, it could only be observed. Data from stations were transmitted by telegraphs into "NII-4" where ballisticsspecialists calculated orbital parameters. The complex became an early prototype of the Soviet Mission Control Center[ru icon [http://nauka.relis.ru/26/0507/26507086.htm Mission Control Center: Labour, Joys and Ordeals] ]

S. Lidorenko. Two of them powered the radio transmitter and one powered the temperature regulation system. They were expected to fade out in two weeks, but ended up working for 22 days. The power supply was turned on automatically at the moment of the satellite's separation from the second stage of the rocket.

The satellite had a one-
watt, 3.5 kg radiotransmitting unit inside, developed by V. I. Lappo from "NII-885," that worked on two frequencies, 20.005 and 40.002 MHz. Signals on the first frequency were transmitted in 0.3 sec pulses (under normal temperature and pressure conditions on-board), with pauses of the same duration filled by pulses on the second frequency. [ [http://rgantd.ru/vzal/korolev/pics/015_007.jpgForm of Signals of the First Earth's Artificial Satellite] - a document at the website of Russian state archive for scientific-technical documentation] 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. A temperature regulation system contained a fan, a dual thermal switch, and a control thermal switch. If the temperature inside the satellite exceeded 36 °C the fan was turned on and when it fell below 20 °C the fan was turned off by the dual thermal switch. [http://www.space-ru.com/russian-satellites/satellite-sputnik-1/ Satellite Sputnik-1] ] If the temperature exceeded 50 °C or fell below 0 °C, another control thermal switch was activated, changing the duration of the of radio signal pulses. Sputnik 1 was filled with dry nitrogen, pressurized to 1.3 atm. [http://www.arrl.org/news/features/2007/09/28/03/ Sputnik and Amateur Radio] ] For the pressurecontrol the satellite had a barometricswitch, activated when the pressure inside the satellite fell below 0.35 kg/cm² (approx. 0.34 atm), changing the duration of radio signal impulse.
While attached to the rocket, Sputnik 1 was protected by a cone-shaped
payload fairing, with a height of 80 cm and an aperture of 48 degrees. The fairing separated from both Sputnik 1 and the rocket at the same time when the satellite was ejected. Tests of the satellite were conducted at OKB-1 under the leadership of O. G. Ivanovsky. Sputnik 1 was launched by an R-7 rocketon October 4, 1957. It burned up upon re-entry on January 4, 1958.
Launch and mission
The control system of the Sputnik Rocket was tuned to provide an orbit with the following parameters: perigee height - 223 km, apogee height - 1450 km, orbital period - 101.5 min.ru icon [http://epizodsspace.testpilot.ru/bibl/vetrov/korolev-delo/03-03.html#36 Main Results of the Launch of the Rocket with the First ISZ Onboard on October 4, 1957] - document signed by S.P.Korolev, V.P.Glushko, N.A.Pilyugin and V.P.Barmin, in the book by Vetrov "Korolev and His Job"] A rocket trajectory with these parameters was calculated earlier by

The Sputnik Rocket was launched at 19:28:34
UTC, on October 4, 1957, from Site No.1at NIIP-5. [es icon [http://www.tecnocosmos.com/archivo/1957/1957001b.htm Sputnik 1] ] Processing of the information, obtained from the "Tral" system showed that the side boosters separated 116.38 seconds into the flight and the second stage engine was shut-down 294.6 seconds into the flight. At this moment the second stage with PS-1 attached had a height of 223 km above Earth's surface, a velocity of 7,780 m/s and velocity vector inclination to the local horizon was 0 degrees 24 minutes. This motion resulted in an orbit with initial parameters: perigee height - 223 km, apogee height - 950 km, initial orbital period - 96.2 minutes.
After 314.5 seconds PS-1 separated from the second stage and at the same moment at the small "Finnish house" of IP-1 station Junior Engineer-Lieutenant V.G.Borisov heard the "Beep-beep-beep" signals from the radio receiver R-250. Reception lasted for two minutes, while PS-1 was above the horizon. There were many people in the house, both military and civil, and they were probably the first to celebrate the event.

On the first orbit the
Telegraph Agency of the Soviet Union(TASS) transmitted: "As result of great, intense work of scientific institutes and design bureaus the first artificial Earth satellite has been built".

Korolyov had intentionally requested reflective panels placed on the booster in order to make it so visible. The satellite itself, a small but highly polished sphere, was barely visible at sixth magnitude, and thus more difficult to follow optically. Ahead of Sputnik 1 flew the third object - the payload fairing, 80cm-long cone, i.e. a little bit bigger than the satellite.
Teams of visual observers at 150 stations in the United States and other countries were alerted during the night to watch for the Soviet sphere at dawn and during the evening twilight. They had been organized in

Controversy surrounding re-entry
Long-standing official accounts state that, based on the degradation of Sputnik 1's orbit, the satellite re-entered the atmosphere on or about January 4, 1958, whereupon it is assumed to have burned up completely. The Sputnik 1 rocket booster re-entry was expected to occur somewhere above Alaska, or the West coast of North America, according to Soviet predictions in December 1957.cite web | url=http://www.journalnow.com/servlet/Satellite?pagename=WSJ/MGArticle/WSJ_BasicArticle&c=MGArticle&cid=1149193257486 | title=Charred debris questioned as pieces of Sputnik to go on tour | accessdate=2007-10-04 | date=February 18, 2007 | publisher=journalnow.com]
There are dubious claims however, that certain components did survive: Per recent news reports, on the morning of December 8, 1957, Earl Thomas of Encino, California, was leaving his home to go to work, when he noticed something glowing beneath a tree in his back yard. The source turned out to be several pieces of plastic tubing, which he claimed matched structural diagrams of the Sputnik 1 satellite. A local Los Angeles radio DJ, Mark Ford of KDAY Radio, was at the same time offering a $50,000 reward for anyone who had found Sputnik, which reportedly had gone down in the L.A. area. When Thomas tried to claim the reward, he was met by a representative of the United States Air Force, who received the pieces Thomas found, and wrote a receipt on Air Force stationery. Later, after the radio station denied having offered a reward, Thomas brought the receipt back to the Air Force, where the sergeant on duty gave the pieces back to Thomas. The family wrote to government officials at all levels in an attempt to collect the reward, but were told that the government had not offered a reward. Of particular interest, however, was a reply from Colonel W.G. Woodbury of the Air Force, which includes the statement "At the time you recovered the Sputnik parts..." Currently, the disputed parts are in the possession of Bob Morgan, Thomas' son.

*In a flashback section of the "" episode "
Carbon Creek", a Vulcan starship is in orbit around Earth in early October of 1957, and its crew closely observes the Sputnik I satellite.
*Sputnik is also the name of a track by
electronic dance musicartist Zoo Brazil from his 2008 Album.
In 2003 a back-up unit of Sputnik 1 called "model PS-1" failed to sell on
eBay. [cite web |url=http://www.collectspace.com/archive/archive-0603.html#0606031146 |title=Sputnik sale crashes |publisher=collectSPACE] It was offered while still on display in a science institute near Kyiv. It is estimated that between four and twenty models were made for testing and as replicas.
A Sputnik 1 model was given as a gift to the
United Nationsand now decorates the entry Hall of its New York CityHeadquarters.
What is thought to be a backup of Sputnik 1 now hangs at The Museum of Flight in Seattle, Washington. The craft was manufactured by the Soviet Academy of Sciences and has battery acid remnants on the inside walls of the spherical shell, as well as fittings for the various components, suggesting that it was more than just a model.
