The Van Allen belts are areas of highly charged particles, mainly electrons and protons, but also with smaller amount of alpha particles.
The dangers to the craft are in the form of radiation which can interfere with, disrupt and damage sensitive electrical equipment. In some space flights electrical equipment has been turned off whilst passing through the belts in order to prevent damage. Of course, space craft also have built-in screening to minimise radiation risks.
To protect astronauts from radiation dangers, spacecraft are fitted with various types of shielding, such as aluminum shielding, and the astronauts also wear protective clothing during this part of their journey. Also the courses/paths were plotted so that the craft would travel through the parts of space where the Van Allen belts are at their thinnest. Despite these precautions, there were and are still serious radiation considerations.
Using calculations of the amount of radiation, the actual time spent passing through the belts, and the shielding used by the Apollo crew, scientists reckoned that the Apollo spacecrafts would pass through the Van Allen belts so quickly that space travellers would not receive any significant life or health-threatening levels of exposure to radiation risks during their flights.
But the matter is not clear cut. There was and is a risk, even if infinitely small. For example, cancers are caused by cell mutation. And sometimes it takes many years for cancer to become evident in a person exposed to harmful radiation. In the Apollo missions the probability of risk was considered to be so small as to be 'nil' for all practical purposes.
Post-flight Developments: In more recent years NASA has reported cases of eye cataracts developing in the majority of astronauts after returning to earth, some within 4 to 5 years of returning, other cases taking 10 or more years to become apparent. Scientists have long known that there is a causal relationship between radiation exposure and cataracts, but whether the astronauts' eye disorders occurred as the direct consequence of passing through the Van Allen belts, or by other radiation in space, or by entirely non-space-flight-related factors is unknown.
Summary: The astronauts got through the Van Allen belts by speed, shielding and carefully planned flight paths, but whether they did so without harm has yet to be determined.

In the backpack there is computer monitoring temperature so hot or cold liquids can be pumped through suit to keep astronaut comfortable as temps range from well as water for drinking and a tank of oxygen to breathe and a back up oxygen tank and in Apollo suits there included a pipe for going to the toilet. I think that covers it but might be a few more bits.
No. Halley's Comet barely gets past the orbit of Neptune, and not by much. It is well short of reaching into the Kuiper Belt.
The only place astronauts have been other than Earth, is on the Moon. Between 1969 and 1972 there were 6 moon landings. Nobody has gone to the Moon since then and nobody has gone to any other planets yet. Most astronauts now just orbit the Earth on one of the Space Shuttles or on the International Space Station or one of the other spacecraft that some countries have. It will be a long time before it will be possible to send astronauts to other planets.
The Messenger spacecraft is a robotic probe sent to Mercury. There are no living things aboard, certainly not people. No human beings have gone farther than about 300 miles into space for the past 40 years. (That's like 1/2 the distance from New York to Chicago, and like 0.1 percent of the distance to the moon.)
The past tense for arise is arose.
Their spacecraft was enough to protect them from the Van Allen belt. The radiation they received while going through it was no more than a normal chest x-ray.
3 astronauts flew on multiple Apollo missions * Jim Lovell - Apollo 8, Apollo 13 (intended to land) * John Young - Apollo 10 (later landed on Apollo 16) * Eugene Cernan - Apollo 10 (later landed on Apollo 17) No astronaut has walked on the moon more than once. Additionally 3 astronauts would have flew on multiple Apollo missions and possibly walked on the moon more than once had the program continued past Apollo 17 * Dick Gordon - Apollo 12 (had been slated to land on Apollo 18) * Fred Haise - Apollo 13 was scheduled for Apollo 19 * Stuart Roosa - Apollo 14 (he had also been slated to land on the moon with Apollo 20)
Because there is no known life on the moon. The rocks brought back by the Apollo astronauts showed no evidence of life in the past either.
From Encyclopedia we can get a list of famous & not famous astronomers & astronauts of the past & present.
The past tense of belt is belted.
No. The Kuiper belt is out past the orbit of Neptune.
Yes it is.
The Kuiper belt is a donut shaped area that is past Neptune. the Oort cloud is sphere shaped and is an area past Pluto.
