Explorer 1 became the first successfully launched satellite by the United States when it was sent to space on January 31, 1958. New York, Explorer 1 was the first U.S. satellite and the first satellite to carry scientific instruments.

They launched the United States into space and showed that it was possible to do science from orbit. (2020 Ford Explorer 1)

You will receive a verification email shortly. Vanguard, according to NASA, was chosen because it had more overtones of a civilian program — a policy decision going all the way up to President Dwight Eisenhower, who did not want the appearance of using ballistic rockets intended for military purposes to usher in the new Space Age. 1. NASA has greenlit a mission to explore the origins of the universe and collect data on more than 300 million galaxies along with more than 100 million stars in the Milky Way.

Explorer 1's launch was a large policy coup, to be sure, but what was also interesting was the science the little satellite beamed back. The latter rocket was based on an Army rocket designed by German scientist Wernher Von Braun, who worked on the V-2 missile program that sent bombs to England during World War II. The satellite also helped buttress the nation's technological confidence in the eyes of the world. - Cosmic-ray detector- Micrometeorite detector, Launch Date: It was a coup for Soviet rocket technology, and led some to muse that bombs could be launched just as easily as a satellite. Explorer 1 was the United States' first satellite in space. In this case, however, NASA wanted to take advantage of the probes being in space at the same time as SAMPEX. Explorer 1: The Beginning of American Space Science, Site Editors: Tony Greicius, Randal Jackson, Naomi Hartono. Dark colors absorb more heat, and white absorb less. This is the first time that two spacecraft simultaneously studied the belts. The ones that are most remembered today are Vanguard — under development by the Navy — and Juno. It was a good night for the Germans, as well as for the American space program. Explorer 1 spawned a series of other satellites. Rocket and satellite engineers quickly got to work, trying to prove they were also capable of launching into space. NASA painted the instrument portion of the satellite white and dark green, which was supposed to regulate temperatures on the section. Then history intervened. May 23, 1958: Explorer 1 makes its final transmission to Earth.

Explorer 1’s last transmission was received May 23, 1958, although it remained in orbit until March 31, 1970. Of Explorer 1's 30 pounds, more than 18 pounds of that was made up of instruments. On that count, NASA succeeded. A pair of NASA CubeSats flying to Mars are opening a new frontier for small spacecraft. Explorer 1 sent data back to Earth for four months, ceasing communications on May 23, 1958.

Shortly after their launch, the probes were turned on to supplement data from the SAMPEX (Solar, Anomalous, and Magnetospheric Particle Explorer) mission before the latter mission was concluded. © Watch live: NASA to announce moon discovery today, NASA to announce 'exciting new discovery' about the moon today, NASA SLS megarocket shortage causes tug-of-war between moon missions, Europa exploration, Volcanoes fuel gaseous atmosphere on Jupiter's moon Io, Life on Earth: Why we may have the moon's now defunct magnetic field to thank for it. Space is part of Future US Inc, an international media group and leading digital publisher. March 31, 1970: After more than 58,000 Earth orbits, Explorer 1 re-entered Earth's atmosphere and was destroyed. The satellite, which was designed, built and operated by the NASA Jet Propulsion Laboratory, carried a cosmic ray detector, which lead to Explorer Principal Investigator Dr. James Van Allen's discovery of radiation belts around Earth held in place by the planet's magnetic field. Examining how the radiation belts protect Earth from high-energy particles; Finding that the belts' shape depends on what kind of electrons are being studied (which means that depending on the electron being looked at, the belts can be unified or separate); Ongoing studies on how the belts change during geomagnetic storms.

Explorer 1's ride to space came through a complicated set of circumstances. Get the latest updates on NASA missions, watch NASA TV live, and learn about our quest to reveal the unknown and benefit all humankind. January 31, 195810:48 p.m. EST (03:48 UTC, February 1), Launch Location: Cape Canaveral Air Force Station, Florida. NASA.gov brings you the latest images, videos and news from America's space agency. 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. The existence of these radiation belts was confirmed by another U.S. satellite launched two months later, and they became known as the Van Allen Belts in honor of their discoverer. May 23, 1958: Explorer 1 makes its final transmission to Earth. Hier können Sie Inhalte sammeln, auswählen und Anmerkungen zu Ihren Dateien hinterlegen. Explorer 3, launched in March 1958, discovered these magnetic field belts. Explorer 1 discovered the Van Allen belts, and subsequent missions in the Explorer series uncovered more details about their nature. World Space Week 2020 will celebrate the impact of satellites on humanity from Oct. 4 to Oct. 10. Its prime science experiment was a cosmic ray detector designed by James Van Allen, a physicist at the University of Iowa. The probes' mission is still ongoing, but some of the key science findings include: Join our Space Forums to keep talking space on the latest missions, night sky and more! A female team of scientists at NASA's Jet Propulsion Laboratory calculated the rocket's trajectory, and team member Barbara Paulson recalled in an interview that she was the one confirming that Explorer 1 made it safely into space. Die Premium Access-Vereinbarung Ihres Teams läuft bald ab. The launch — revealed only after it was a success — stunned most of the Western world. This repository is populated with tens of thousands of assets and should be your first stop for asset selection. (Image: © NASA/Jet Propulsion Laboratory).

It is not typical for a mission to start science observations right away as the instruments are still being configured.

Enter Search Criteria. Unfortunately, the rocket exploded moments after the launch in front of TV cameras. The satellite remained aloft for more than a decade before re-entering Earth's atmosphere on March 31, 1970. Click here to request Getty Images Premium Access through IBM Creative Design Services. Cosmic rays are energetic radiated particles from space — bits of atoms that can include protons, electrons or nuclei. Explorer 1 successfully flew into space on Jan. 31, 1958. Besides the cosmic ray detectors, it also carried experiments such as temperature sensors (both internal and external) and a microphone to listen for micrometeorites hitting the satellite.
