On Monday the 31st, the first manned mission to fly directly above the polar regions of the Earth took off in a SpaceX Falcon 9. It is a private mission, some say they are space tourists, but they are also going to do some type of experiment and are already taking truly impressive images.
And it is not the first time that they have photographed the poles, there are many images of the poles, which is the first time astronauts have flown over the poles and there is an explanation. The Fram2 mission is called in homage to the famous Norwegian polar expedition ship called Fram, by the way, Frank in Norwegian means forward Like, that ship was used to explore the north pole, the south pole between 1893 and 1912, it was used by several Norwegian explorers including the famous Roald Amundsen.
This particular space mission should last 3 to 5 days and is giving us impressive images, but we had plenty of images of the poles, the poles are well monitored. Why don't astronauts even from the international space station fly over the poles? Well, because there is a very powerful reason and that is that the poles receive a lot of radiation, that's why you see the northern lights because there is like a kind of dumping ground for the Earth's magnetic field. Here I have a curious question: they are going to receive a lot of radiation. cosmic.
The previous Polaris mission managed to reach 500 or so kilometers away from the Earth, which is a lot, the astronauts of the international space station are around 400 - 420 km high from the Earth no more, in fact no human has gone further since the Apollo missions, that Polaris mission, the previous one that Space Allen at least in the lower and for quite a long time.
I have a doubt, this mission that these astronauts are going to receive are going to receive astronauts or space tourists or whatever you want to call them, they are going to receive a large amount of large doses of radiation, it will be part of an experiment where SpaceX wants to collect information about the effect of cosmic radiation on human health for the topic of trips to Mars, I have that doubt.
If the astronauts do not fly through the poles it is precisely because of the issue of radiation, the Apollo missions also crossed the Van Allen belts, but they were simply passing by, they passed by and there in the Van Allen belts they only spent a few minutes heading to the moon, while in the previous Polaris mission they spent quite a long time and in fact it was one of the parts of the mission, to analyze the effects of radiation on human health.
The Van Allen belts are an area where a large amount of radiation is also concentrated, because the Earth's magnetic field is quite complex. If the poles are a kind of dumping ground where a large amount of cosmic radiation falls, the Van Allen belts also concentrate a lot of radiation.
We do not know if the cabin of the Manned Dragon ship has any special coating against radiation, perhaps it does and they are testing it, keep in mind that they are about to carry out missions to the moon and then Elon Musk is determined to prioritize missions to Mars and that has to happen in the coming years, perhaps they are experiencing these types of issues.

One key reason crewed polar orbits weren't done in the past is also communication blackouts. Starlink from Dragon as reduced this problem which makes it safer now than before.
