There is a life on Muwei Er?NASA plans to launch spacecraft in 2024 to explore

Science Fiction Network June 13 (Wang Ziyu) Satellite is a natural celestial body surrounding the planet track. The moon is the only satellite of the earth. However, in the solar system, the planets with satellites have more than 6 satellites. Among them, Muwei Er is also known as Europa. Its area is slightly smaller than the moon, but the diameter also reaches 3100 kilometers. It is wrapped in a thick ice shell on its surface. For many years, scientists have always believed that there is a liquid ocean under the ice, which may be suitable for life.

In order to explore whether there is an extraterrestrial life under the ice of Mu Weiji, NASA is developing a spacecraft that can access Europa. It is reported that the spacecraft is called Europa Clipper, which will be launched in 2024. However, it is difficult to launch to Muwei II, because Muwei is about 900 million kilometers away from the earth, and it takes more than two years to fly over.

According to scientists, Mu Weiji's potential ocean is under the ice of 10 to 15 miles. In order to explore Muwei Er, the launching spacecraft will be equipped with nine scientific instruments, including a spectrometer and a heat portrait. These instruments can measure information such as the depth, salinity, thickness, and atmosphere under the two ice surface of the wooden guard.

The spacecraft is a cylindrical shape made of aluminum, about 3 meters high, about 1.5 meters wide, which includes key components such as electron and radio systems. In addition to the spacecraft system and instrument, another key part is its engine, which will support it to Muwei Er in a 1.8 billion mile journey. According to scientists, the engine of the spacecraft can also be used for large maneuvers. When it is close to Jupiter and requires a lot of burning to be used in handy when the Jupiter's track is captured. It can also be used for smaller maneuverability to fine -tune the accurate flying over the Europa and other solar system along the way.

In addition, scientists also want to study the water columns sprayed from Muwei Er Crims. Because Muwei Er will generate heat under the action of gravity, these gravity pulls Muwei two to the surroundings and heats it inside, which will make the water from freezing. The produced water columns can help the ocean and cycles under the mixed surface are important chemicals that are important to life, such as carbon, hydrogen and oxygen.

At present, JPL has announced that it has received the main body of the spacecraft in Southern California facilities, and now it will start installing and testing the instruments of the spacecraft and other key components.
