Why is it called the Van Allen belt?

A Van Allen radiation belt is a zone of energetic charged particles, most of which originate from the solar wind, that are captured by and held around a planet by that planet's magnetosphere. ... The belts are named after James Van Allen, who is credited with their discovery.

How did NASA get past the Van Allen radiation belt?

Scientists suggested that a moderate amount of protection could shield a crew from the outer Van Allen belt particles. In 1962, Van Allen – believing that protons of the inner belt could seriously threaten human spaceflight missions – suggested clearing them away by setting a nuclear bomb off near the outer belt.

What did Van Allen a do?

Van Allen, in full James Alfred Van Allen, (born Sept. 7, 1914, Mount Pleasant, Iowa, U.S.—died Aug. 9, 2006, Iowa City, Iowa), American physicist, whose discovery of the Van Allen radiation belts, two zones of radiation encircling Earth, brought about new understanding of cosmic radiation and its effects on Earth.

How do we get through the Van Allen belt?

Them. First there's the inner belt which is comprised of protons.

Does Mars have a Van Allen belt?

Mars does not have a magnetic field of any strength and so does not have a van Allen belt (and this is a serious problem for potential human exploration of the planet). Similarly, neither Venus nor Mercury (nor the Moon, which is arguably part of a two-planet system with the Earth) have a van Allen belt.

How many times have we been to the Moon?

The United States' Apollo 11 was the first crewed mission to land on the Moon, on . There were six crewed U.S. landings between 19, and numerous uncrewed landings, with no soft landings happening between 22 August 1976 and 14 December 2013.

Can you see the American flag on the moon with a telescope?

Yes, the flag is still on the moon, but you can't see it using a telescope. ... The Hubble Space Telescope is only 2.4 meters in diameter - much too small! Resolving the larger lunar rover (which has a length of 3.1 meters) would still require a telescope 75 meters in diameter.

Can astronauts pass the Van Allen Belt?

For near-Earth missions, the Van Allen belts are not a hazard to spacefarers. It was, however, a hazard for the Apollo missions. The Van Allen belts are not a physical barrier to spacecraft, and so, in principle, we could have sent the Apollo spacecraft through the belts. It would not have been a good idea.

What altitude are the Van Allen Belts?

An inner Van Allen belt extends from an altitude of about 1,000 to 8,000 miles (1,600 to 13,000 km), compared to the orbital altitude of the International Space Station (240 miles, or about 390 kilometers). The outer radiation belt extends from 12,000 to 25,000 miles (19,000 to 40,000 km) in height.

Why is the Van Allen belt important?

The Van Allen Radiation Belts are one part of Earth's dynamic magnetic environment, known as the magnetosphere. During periods of intense space weather, the density and energy of radiation belt particles can increase and pose a danger to astronauts, spacecraft, and even technologies on the ground.

Can you see the American flag on the Moon with a telescope?

Yes, the flag is still on the moon, but you can't see it using a telescope. ... The Hubble Space Telescope is only 2.4 meters in diameter - much too small! Resolving the larger lunar rover (which has a length of 3.1 meters) would still require a telescope 75 meters in diameter.

How many countries have sent man to the Moon?

One of their craft became the first to land on the far side of the Moon....How Many Countries Have Landed a Spacecraft on the Moon?

Country	Successful Moon Landings
United States	11, including 6 manned missions
Soviet Union (Russia)	8
China	3

Which planet is most radioactive?

Jupiter is the most massive planet but if the bulk of it's mass comes from gaseous elements instead of heavier ones like uranium or whatever than it being the most massive might not necessarily mean it has the most radioactive material. That I pretty much agree with.

Who reached on Mars first?

The first to contact the surface were two Soviet probes: Mars 2 lander on November 27 and Mars 3 lander on Decem—Mars 2 failed during descent and Mars 3 about twenty seconds after the first Martian soft landing.

Is the flag still on the Moon?

Unfortunately, the six flags planted on the lunar surface from 1969 through 1972 haven't fared so well. Images taken by NASA's Lunar Reconnaissance Orbiter in 2012 showed that at least five out six flags were still standing. ... The flags are probably completely bone-white by now, as we first learned from Gizmodo.

Why did NASA stop going to the Moon?

But in 1970 future Apollo missions were cancelled. Apollo 17 became the last manned mission to the Moon, for an indefinite amount of time. The main reason for this was money. The cost of getting to the Moon was, ironically, astronomical.

Where is Hubble now?

Download "Observatory" information as a PDF Launched on Ap, aboard the Space Shuttle Discovery, Hubble is currently located about 340 miles (547 km) above Earth's surface, where it completes 15 orbits per day — approximately one every 95 minutes.

How many countries have walked on the Moon?

How Many Countries Have Landed a Spacecraft on the Moon?

Country	Successful Moon Landings
United States	11, including 6 manned missions

How did Apollo astronauts avoid radiation?

The increased strength of the sun's magnetic field that permeates the solar system acts like an umbrella – shielding the Earth, moon and planets from galactic cosmic rays and therefore lessening the impact on astronaut radiation doses.

Does Mars have Van Allen Belts?

Mars does not have a magnetic field of any strength and so does not have a van Allen belt (and this is a serious problem for potential human exploration of the planet). Similarly, neither Venus nor Mercury (nor the Moon, which is arguably part of a two-planet system with the Earth) have a van Allen belt.
