At Los Angeles Air Force Base in California in June, the Space Force’s Space and Missile Systems Center (SMC) successfully implemented a new anti-jamming capability on the Wideband Global SATCOM (WGS) called Mitigation and Anti-Jam Enhancement (MAJE), according to a recent news release. It orbited for three weeks before its batteries died and then silently for two more months before it fell back into the atmosphere. Sputnik and the Dawn of the Space Age History changed on October 4, 1957, when the Soviet Union successfully launched Sputnik I.
But despite its limited payload and short runtime, the satellite did bring some scientific results.By measuring how the satellite slowly spiraled down from its original orbit, scientists could determine the density of the atmosphere at various altitudes, because rarified air was primarily responsible for the decay of the orbit.
Sputnik, a series of three Soviet artificial satellites. Although President Dwight Eisenhower had tried to downplay the importance of the Sputnik launch to the American people, he poured additional funds and resources into the space program in an effort to catch up. "On the exterior, the top hemisphere was covered by a thermal protective shield one millimeter thick.
Sixty years later, and humanity's first satellite remains one of its most important.Although Sputnik-1 will always be remembered as a shock to Americans, it is surprising how thinly veiled the development of the first satellite in orbit really was. Eventually, lawmakers and political campaigners in the United States successfully exploited the fear of a "missile gap" developing between U.S. and Soviet nuclear arsenals in the 1960 presidential election, which brought John F. Kennedy to power over Eisenhower's vice president, Richard Nixon.

The successful launch came as a shock to experts and citizens in the United States, who had hoped that the United States would accomplish this scientific advancement first. The Sputnik 1 spacecraft was the first artificial satellite successfully placed in orbit around the Earth and was launched from Baikonur Cosmodrome at Tyuratam (370 km southwest of the small town of Baikonur) in Kazakhstan, then part of the former Soviet Union.
Notizie, analisi, multimedia. In the West, however, Sputnik was used as a generic name for Soviet satellites. The Russian word "Sputnik" means "companion" ("satellite" in the astronomical sense). The lone survivor of an enigmatic spaceship incident hasn't returned back home alone-hiding inside his body is a dangerous creature. Sputnik 1 was the first artificial Earth satellite.
The world's first artificial satellite was about the size of a beach ball (58 cm.or 22.8 inches in diameter), weighed only 83.6 kg. It was an event that galvanized the world and spurred the fledgling U.S. space effort into high gear. Leggi su it.sputniknews.com ultime notizie e fatti del giorno in tempo reale.

Its main body was two hemispheres two millimeters thick and connected by 36 bolts. MAJE involves upgrades to both software and hardware in the Army’s Global SATCOM … …Soviet Union orbited the first artificial satellite, arousing fears that the United States was falling behind the Soviets technologically.

Sputnik 1 (launched October 4, 1957) was the first artificial satellite and the beginning of the ‘space race’ between the U.S. and the Soviet Union. On August 3, 1955, head of the commission Leonid Sedov told journalists that his country had already sent vehicles with animals into the stratosphere, and that the Soviet satellite project could come to fruition in the near future.
These concerns were compounded when the United States learned that the Soviet Union also tested the first intercontinental ballistic missile that year.
Sputnik 2 carried the dog Laika, the first living creature in space. As a result, the launch of Sputnik served to intensify the arms race and raise Cold War tensions.
At last, on January 31, 1958, the United States succeeded in launching its first satellite, the Explorer. In this way, the launch of Sputnik fueled both the space race and the arms race, in addition to increasing Cold War tensions, as each country worked to prepare new methods of attacking the other. A special spring mechanism was designed to deploy antennas to the angle of 35 degrees toward the main axis of the container, immediately after the spacecraft had separated from the rocket. Fear that they had fallen behind led U.S. policymakers to accelerate space and weapons programs. This prompted Eisenhower, who generally held the line on spending, to sign the National Defense Education Act of 1958, which provided extensive aid to schools and students in order to bring…
At 184 pounds, the Russian satellite was much heavier than anything the United States was developing at the time, and its successful launch was quickly followed by the launch of two additional satellites, including one that carried a dog into space.
