Why Pocket Sheds in the American desert are they worth the exorbitant price?

Some time ago, the Yutu-2 lunar rover photographed a “mystery cabin” on the moon. After the photo was exposed, it sparked heated discussions and debates among netizens at home and abroad. people have big ideas. Kai speculated that this "hut" was the "Guanghan Palace", "Kai Tuo Gate", and the "Alien Base". The 38th lunar day, Yuetu-2 finally approached this “mysterious hut” and revealed its true face.

According to the National Space Administration, on the 36th lunar day, on the far side of the Moon, Yutu 2 discovered a very steep cube on the northern horizon, which looked like a mysterious “hut”. also an “impact crater”. After measurements, researchers found that Yutu 2 was about 80 meters from the "mysterious hut", and it would take at least two or three months to get closer and observe it in detail.

Seeing this, many people may want to ask why does it take so long to get so close? In this regard, some experts explained that although Yutu 2 can reach a speed of 200 meters per hour at its fastest speed, moving on the Moon is completely different from moving on Earth. On the one hand, Yutu 2's main task is to explore the moon rather than travel.ger, it was therefore not designed to operate at high speed.

On the other hand, it is difficult for Yutu-2 to reach the moon once, and so it must detect data on the lunar surface as detailed as possible, whether it encounters craters of impact or small size. rocks, as long as they are considered to have research value, the lunar rover will stop to study and analyze carefully. In addition, the main energy of Yutu-2 comes from two solar panels, that is, it must work with the sun. A “day” on the moon is very long than a month on earth, and a month is very long. There are 14 days on earth, but Yutu-2 only operates during moonlight hours and sleeps during moonlit nights.

When the time entered the 38th lunar day, Yutu 2 finally approached the "mysterious cabin" mentioned above. The researchers immediately installed a panoramic cameraThe "hut" is as tall as Kailumen, but turns out to be very short when approached. It looks like a "Jade Rabbit" ". The stones scattered in front are like a "carrot", and the round stone beads in the back are found like the products of the "Jade Rabbit" meal. The whole picture is full of fun.

< p>Next, Yutu 2 will continue to move towards this stone to closely study its origin and the crater behind it. At the same time, Yutu 2 recently crossed the 1,000 meter mark and is currently operating under normal conditions. look forward to Yutu 2 continuing to “advance” and leading us to discover more of the magic and mysteries of the universe

According to an American media on November 13, 2017According to some. information, a Wild West-style wooden frame cabin is on the market in the southern desert area-west of a small town in California, United States. The price reached US$120,000 (around RMB 800,000). This wooden cabin measures 150 square feet (about 14 square meters), which is an exorbitant price!

Pioneertown is an ancient town that was built into a popular city by Hollywood investors in 1947. Most of the area here is desert, which is very suitable for filming movies. However, the population living in the city is not very large. In 2006, the town had 350 inhabitants.

In fact, this place is not suitable for family life, but only for occasional rest or vacation. Although a solar system is installed in the cabin, there is no running water, no toilet or bathroom and no kitchen. As the cabin is located in a 2.5 acre desert area where water is scarce, there is no water supply.

Living here requires a lot ofcourage and adventurous spirit, as it is essentially surrounded by bare desert, with only sparse bushes, and the cabin seems particularly lonely in the desert.
