Explorer 1 was launched on January 31, 1958 at 22:48 Eastern Time (February 1, 03:48 UTC) atop the first The U.S. Earth satellite program began in 1954 as a joint The total mass of the satellite was 13.37 kilograms (30.80 lb), of which 8.3 kg (18.3 lb) were instrumentation. Explorer 1 was the first satellite launched by the United States and was part of the U.S. participation in the International Geophysical Year. The satellite remained aloft for more than a decade before re-entering Earth's atmosphere on March 31, 1970.Explorer 1 spawned a series of other satellites.

The Soviet Union launched it into an elliptical low Earth orbit on 4 October 1957. It took about 98 minutes for Sputnik I to orbit the Earth on its elliptical path. This calculates to an average impact rate of 8.0An identically constructed flight backup of Explorer 1 is on display in the Preliminary satellite tracking tests in a field near JPLTrajectory calculations were done by hand by this group of women. Today, they are known as the Of Explorer 1's 30 pounds, more than 18 pounds of that was made up of instruments. engines. While Explorers 2 and 5 failed due to rocket stage problems, Explorers 3 and 4 both launched successfully in 1958 and transmitted science from orbit.Even though the satellites are no longer working, their legacy remains.

On that count, NASA succeeded. The United States had at least three main rocket options for sending the satellite into space. For the Iranian Explorer-1 rocket, see Explorer 1 in its orbital configuration, with the launch vehicle's fourth stage attachedMatt Bille and Erika Lishock, The First Space Race: Launching the World's First Satellites, Texas A&M University Press, 2004, Chapter 5X-minus 80 Days - JPL-Army Ballistic Missile Agency Explorer 1 was sent into space on a rocket launcher named Juno. 2001. the first American satellite crashed in 300 BC it also had no.

The latter rocket was based on an Army rocket designed by German scientist The satellite was supposed to launch as the United States' contribution to science during International Geophysical Year (which ran from 1957-1958). It signaled that the country was ready to explore the universe.Explorer 1's ride to space came through a complicated set of circumstances. This article is about the U.S. satellite. Then history intervened. NASA was established in 1958 to keep U.S. space efforts abreast of recent Soviet achievements, such as the launching of the world’s first artificial satellite– Sputnik 1 –in 1957. A female team of scientists at NASA's Jet Propulsion Laboratory calculated the rocket's trajectory, and team member The little satellite detected fewer cosmic rays in its orbit (which ranged from 220 miles from Earth to 1,563 miles) than Van Allen expected.The physicist proposed this might be because radiation in Earth's magnetic field may prevent the cosmic rays from coming in. It was 58 cm (23 in) in diameter and a polished metal sphere with four external radio antennas to broadcast radio pulses. On Jan. 31, 1958, the United States launched its first successful satellite: Explorer 1. Several other color schemes had been tested, resulting in backup articles, models, and photographs showing different configurations, including alternate white and green striping and blue stripes alternating with copper.
