How did it take to get to the moon?

It takes about 3 days for a spacecraft to reach the Moon. During that time a spacecraft travels at least 240,000 miles (386,400 kilometers) which is the distance between Earth and the Moon. The specific distance depends on the specific path chosen.

How did astronauts get past the Van Allen 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.

Where does space start?

Kármán line
The Kármán line, an altitude of 100 km (62 mi) above sea level, is conventionally used as the start of outer space in space treaties and for aerospace records keeping. The framework for international space law was established by the Outer Space Treaty, which entered into force on 10 October 1967.

What is radiation from space?

Space radiation is comprised of atoms in which electrons have been stripped away as the atom accelerated in interstellar space to speeds approaching the speed of light – eventually, only the nucleus of the atom remains. Space radiation also has very different effects on human DNA, cells and tissues.

Why did NASA send astronauts to the Moon through the belts?

For the Apollo trips, we wanted to send the astronauts through a sparse region of the belts, and to try and get through them quickly. This was necessary in any case; the crafts had to make it to the Moon in a reasonable amount of time, and the shorter the trip, the less exposure to all sorts of radiation the astronauts would get.

How do NASA’s Van Allen Probes orbit through the belts?

NASA’s Van Allen Probes orbit through two giant radiation belts that surround Earth. Their [+] observations help improve computer simulations of events in the belts that can affect technology in space.

What problems did the Apollo program Face on its trip to the Moon?

The Apollo program encountered many difficulties on its trip to the Moon, ranging from mechanical to astrophysics. The issue of the Van Allen belt and its radioactivity was a particularly serious concern while planning the mission.

Where are the radiation belts located in space?

Geosynchronous communications satellites orbit just inside the outer edge of the outer radiation belt, and the low-Earth orbit (LEO), where the International Space Station and the Hubble space telescope are, is just below the inner edge of the inner belt. The radiation belts are not the only structures surrounding Earth.
