According to the DailyMail, NASA decided to send a robot to the sun to have more information about the dangerous activity of the sun. It is a protection action against a danger that could threaten human existence on earth.
The spacecraft will move closer at a distance to within 4 million miles of the sun’s surface next year. Named “the Solar Probe Plus (SPP)”, this mission will be the first of its kind in history. Indeed, the spaceship will be seven times closer to the surface of the sun than any other spacecraft has done before.
For a long time, NASA scientists have always wanted to send a probe through the outside atmosphere of the sun. They wanted to learn about the solar wind and the material it carries in our solar system.
To survive its mission, the spacecraft will need to withstand temperatures outside the spacecraft of 2,500 degrees Fahrenheit (1,377 degrees Celsius). So, it will be made of a 4.5 inch-thick (11.43 cm) carbon-composite shield.
Predict a huge solar event
According to NASA, this mission could help predict a “huge solar event”.
A recent study by the National Academy of Sciences has estimated that without notice a huge solar event could cause two billion dollars of damage in the United States leaving its east coast without electricity for a year.
Being the source of the solar wind, the sun emits a flow of gas that crosses the earth at speeds of more than one million miles per hour. Then, disturbances in this wind will shake the magnetic field of the Earth and pump energy into the radiation belts.
“This mission will provide insight on a critical link in the Sun-Earth connection. Data will be key to understanding and, perhaps, forecasting space weather. Until we can explain what is going on up close to the sun, we will not be able to accurately predict space weather effects that can cause havoc at Earth”, said NASA.
