Can astronauts pass through 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.

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. I found some statistics on the size of lunar equipment in a Press Kit for the Apollo 16 mission. The flag is 125 cm (4 feet) long, and you would need an optical wavelength telescope around 200 meters (~650 feet) in diameter to see it.

Is the discharge between Earth and moon ever possible?

And 2 electrons can't kill a human being. And no phenomena can produce a potential difference between the Earth and the Moon which is big enough for a discharge because there is nothing to ionise in the vacuum of space.

Are the Van Allen belts radioactive?

The Apollo missions marked the first event where humans traveled through the Van Allen belts, which was one of several radiation hazards known by mission planners. The astronauts had low exposure in the Van Allen belts due to the short period of time spent flying through them.

Is there a barrier between Earth and space?

The Kármán line (or von Kármán line /vɒn ˈkɑːrmɑːn/) is an attempt to define a boundary between Earth's atmosphere and outer space, and offers a specific definition set by the Fédération aéronautique internationale (FAI), an international record-keeping body for aeronautics.

The Van Allen Belts Are Lethal, This Is How Astronauts Fly Through Them

How far from Earth is the Van Allen belt?

The innermost Van Allen belt sits somewhere between 400 to 6,000 miles above the surface of our planet. Even if the innermost belt is at its closest, the ISS (and the space shuttle in its day) are more than 100 miles away from the Van Allen Belts.

Are astronauts protected from radiation?

When astronauts travel away from the planet's surface and into space, they are no longer protected by it and so are exposed to radiation. That means solutions to the radiation problem have to be considered for space missions of all kinds.

Why do we not go back to the Moon?

Human Moon landings require more resources than robotic landings, since humans require water, oxygen, food, and other amenities to remain alive. That said, several nations—including private companies from those nations—are working on robotic Moon initiatives that could support future human missions.

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.

How cold is space?

The Cosmic Background Explorer (COBE) satellite has refined temperature measurements taken way back in 1964. According to data from the Cosmic Background Explorer (COBE) satellite, the temperature of space is 2.725K (2.725 degrees above absolute zero).

What's at the edge of space?

Called the “Kármán line”, it marks the beginning of space at 100 km above Earth's mean sea level. All of these definitions, Horner says, are “equally as good as each other and equally bad as each other.

How far has a human gone in space?

Farthest away

In April 1970, the crew of NASA's Apollo 13 mission swung around the far side of the moon at an altitude of 158 miles (254 km), putting them 248,655 miles (400,171 km) away from Earth. It's the farthest our species has ever been from our home planet.

How strong is Van Allen radiation belt?

The inner Van Allen belt consists largely of highly energetic protons, with energy exceeding 30,000,000 electron volts. The peak intensity of these protons is approximately 20,000 particles per second crossing a spherical area of one square cm in all directions.

What is the line between Earth and space?

But to earn their astronaut wings, high-flying civilians will have to make it past the so-called Kármán line. This boundary sits some 62 miles (100 kilometers) above Earth's surface, and it's generally accepted as the place where Earth ends and outer space begins.

What altitude are the Van Allen Belts?

The inner Van Allen belt is located typically between 6000 and 12 000 km (1 - 2 Earth radii [R_E]) above Earth's surface, although it dips much closer over the South Atlantic Ocean. The outer radiation belt covers altitudes of approximately 25 000 to 45 000 km (4 to 7 R_E).

Is there color in space?

Color does not change in space, because the wavelengths remain the same. Although you can see all the colors of the rainbow, plus every color mixture from those colors, you only have three color detectors in your eyes. These color detectors, called cones, have a preference for a particular type of light.

Does space ever end?

No, they don't believe there's an end to space. However, we can only see a certain volume of all that's out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn't had time to reach us yet, so we have no way of knowing such a galaxy exists.

How much of space is undiscovered?

We know only five per cent of the universe. The remaining 95 per cent is still a mystery – an unknown universe of new particles and forces awaits discovery.

Would a body decompose in space?

In space we can assume that there would be no external organisms such as insects and fungi to break down the body, but we still carry plenty of bacteria with us. Left unchecked, these would rapidly multiply and cause putrefaction of a corpse on board the shuttle or the ISS.

How much time on Earth is 1 hour in space?

The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.

What does space smell like?

A succession of astronauts have described the smell as '… a rather pleasant metallic sensation ... [like] ... sweet-smelling welding fumes', 'burning metal', 'a distinct odour of ozone, an acrid smell', 'walnuts and brake pads', 'gunpowder' and even 'burnt almond cookie'.

Has Voyager reached the Oort Cloud?

No missions have been sent to explore the Oort Cloud yet, but five spacecraft will eventually get there. They are Voyager 1 and 2, New Horizons, and Pioneer 10 and 11. The Oort Cloud is so distant, however, that the power sources for all five spacecraft will be dead centuries before they reach its inner edge.

What is the most radioactive planet?

Jupiter is the most radioactive planet. It has the greatest Electromagnetic field of all planets in Solar system according to Juno space mission ( https://en.wikipedia.org/wiki/Juno_(spacecraft) ).
