What is the purpose of Explorer 1?

The primary science instrument on Explorer 1 was a cosmic ray detector designed to measure the radiation environment in Earth orbit. Once in space this experiment, provided by Dr. James Van Allen of the University of Iowa, revealed a much lower cosmic ray count than expected.

What did the Explorer I discover?

Explorer 1's main instrument was a cosmic ray detector designed by James Van Allen of the State University of Iowa. The experiment discovered evidence of radiation belts around Earth, now called Van Allen Belts, that marked the first scientific discovery in space.

What was the weight of Explorer I?

30.8 lb Explorer 1

Spacecraft properties
Manufacturer	Jet Propulsion Laboratory

What is the official name for Explorer 1?

Satellite 1958 Alpha Satellite 1958 Alpha, later and better known as Explorer 1, successfully lifted off from Cape Canaveral, Florida on Jan. 31, 1958. At a jubilant early-morning press conference a few hours later, Pickering, von Braun and Van Allen hoisted a model of Explorer 1 over their heads in what has become an iconic photograph.

How many days on Earth is a year in space?

365 days While earth takes 365 days to make one circuit, the closest planet, Mercury, takes only 88 days. Poor, ponderous, and distant Pluto takes a whopping 248 years for one revolution....The Days (And Years) Of Our Lives.

Planet	Rotation Period	Revolution Period
Neptune	0.67 days	164.79 years
Pluto	6.39 days	248.59 years

Who invented Explorer?

William Hayward Pickering Explorer 1 was launched in quick response by the U.S. It was designed and built in under three months at the Jet Propulsion Laboratory (JPL) by a team led by William Hayward Pickering.

How long was the Explorer 1 in space?

12 years Explorer 1 transmitted data for about four months till its batteries died on . But it remained in orbit for 12 years, circling 58,376 times around Earth, before burning up upon reentry into the atmosphere on Ma.

How many stages did Explorer 1 have?

four Launched late on 31 January 1958 (10:48 p.m. EST, or 03:48 UTC on 01 February) on an Juno-1 rocket (adapted Jupiter-C), Explorer 1 carried instrumentation for the study of cosmic rays, micrometeorites, and for monitoring of the satellite's temperature. The Juno-1 launch vehicle consisted of four propulsive stages.

What was first satellite?

Sputnik 1 spacecraft Description. 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.

Who created Explorer 1?

Jet Propulsion Laboratory Explorer 1/Ditte costruttrici Explorer 1 was launched in quick response by the U.S. It was designed and built in under three months at the Jet Propulsion Laboratory (JPL) by a team led by William Hayward Pickering.

What was the first dog in space called?

Hurriedly prepared to take advantage of the propaganda value of the first satellite, Sputnik 2 utilized an animal habitat and carried the dog Laika, the first animal to orbit the Earth. The event began to galvanize the United States into organizing their space program.

How long is 1 hour in space?

The time dilation on that planet—one hour equals 7 Earth years—seems extreme. To get that, you'd apparently need to be at the event horizon of a black hole.

Which is the only planet that can sustain life?

Earth Understanding planetary habitability is partly an extrapolation of the conditions on Earth, as this is the only planet known to support life.

Is Sputnik still in orbit?

And though it only blasted off some six months after the Soviet's Sputnik satellite, Vanuguard 1 still remains in orbit — more than 60 years later. This makes Vanguard Earth's longest-orbiting artificial satellite, as well as the oldest human-made object still in space. And that's not likely to change any time soon.

What was the first animal to orbit?

dog Laika The first animal to make an orbital spaceflight around the Earth was the dog Laika, aboard the Soviet spacecraft Sputnik 2 on 3 November 1957.

What is the oldest man made object in space?

The Vanguard 1 satellite We believe in the free flow of information Sixty years ago, a grapefruit-sized aluminium sphere with six antennas and some tiny solar cells was launched into Earth orbit. The Vanguard 1 satellite is still up there and is the oldest human-made object in space. It's our first piece of space archaeology.

What are the 3 types of satellites?

Types of Satellites and Applications

• Communications Satellite.
• Remote Sensing Satellite.
• Navigation Satellite.
• Geocentric Orbit type staellies - LEO, MEO, HEO.
• Global Positioning System (GPS)
• Geostationary Satellites (GEOs)
• Drone Satellite.
• Ground Satellite.

Which country has the most satellites?

the United States Of the 3,372 active artificial satellites orbiting the Earth as of Janu, 1,897 belong to the United States. This is by far the largest number of any single country, with their nearest competitor, China, accounting for only 412.

How do astronauts pee and poop?

The bathroom is full of handholds and footholds so that astronauts don't drift off in the middle of their business. To pee, they can sit or stand and then hold the funnel and hose tightly against their skin so that nothing leaks out. To poop, astronauts lift the toilet lid and sit on the seat — just like here on Earth.

Is Laika still in space?

In October 2002, Dimitri Malashenkov, one of the scientists behind the Sputnik 2 mission, revealed that Laika had died by the fourth circuit of flight from overheating. ... Over five months later, after 2,570 orbits, Sputnik 2—including Laika's remains—disintegrated during re-entry on .
