We have heard of spacecraft being sent to planets, satellites and even comets. But this time it is being sent to the sun, whose name is Parker. The purpose is to touch the sun.
The NASA spacecraft will be the first spacecraft in the history of space exploration to penetrate deep into the solar system.
It will cost NASA about দে 1.5 billion to build the Parker and send the vehicle into space. Its size will be equal to a small car. At a distance of about 4 million miles from the sun, this vehicle will continue to revolve around that star.
The vehicle will be launched in June next year. But NASA says it will start revolving around the sun from 2024.
The surface of the sun is very hot. The temperature there is more than 10,000 degrees Fahrenheit.

The spacecraft Parker is being built
That's why the biggest challenge for Parker is to survive the scorching heat. The temperature at which the Sun's atmosphere or the photosphere will continue to revolve is 1300 degrees Celsius or two and a half thousand degrees Fahrenheit.
The atmosphere outside the sun is more difficult and complex. With extreme temperatures there is radiation of radioactive rays.
In the face of all this, Parker will try to find out about the structure of the sun and exactly how this giant star works.
Its speed around the sun will be four lakh 30 thousand miles per hour. It would take less than a minute to travel from New York to Tokyo, Japan.
Nicki Fox, a scientist with the NASA mission, says Parker will orbit the giant sun a total of 24 times.

The biggest challenge for Parker is to survive the extreme temperatures in the solar system.
"The gaseous atmosphere around the sun is where we enter the corona. Many scientists have been researching for decades to unravel the mysteries of this area. Finally, we are now sending a mission there to unravel these mysteries," he said.
Nicki Fox says the day Parker is launched will be a very emotional day for him.
"Both feelings of joy and pain will work. Because I've done a lot of work with this spacecraft. It's connected to the life of every scientist on this mission. It's a lot like sending your child to college. We believe Parker will work properly and that's space." Will send us a lot of information. We are all excited about this mission. I am sure I will cry that day. "

People on Mars
After the sun, let's look at Mars. This time it is not a spacecraft heading towards the planet, people are being sent.
US rocket businessman Elon Musk has announced that he will send people to Mars in 2024.
He told a conference of the International Astronomical Congress in Adelaide, Australia, that his company, SpaceX, would begin building rockets next year.

He said the rockets would be so fast that it would take less than an hour to travel from one city to another in the world. For example, it takes only 40 minutes to go from New York to Shanghai, China. 29 minutes from London to New York.
This may sound like a science fiction story. But
Jonathan Amos, the BBC's science correspondent, says: "Elon Musk is at the forefront of research into the repeated use of a rocket and the development of electric cars. That's why when he says he will take humans to Mars in the next seven years, he must take that dream seriously. "
Elon Musk is busy designing a new rocket suitable for the Mars mission. He named this rocket BFR.
SpaceX says the rocket can carry up to 100 passengers. Not only that, this rocket can fly many times. All you have to do is refuel, and nothing else.

The settlement of Mars in the imagination of Elon Musk
"We want to declare our current vehicles abandoned. We want to build a rocket that will replace our current rockets, the Falcon Nine, Falcon Heavy and Dragon. And if we can do that, we can go after Falcon Nine, Heavy and Dragon." The resources that are being used will be used to build these new rockets. "
Mr. Musk said his SpaceX company is now focusing on the project with the goal of sending people to Mars.
Elon Musk says he has found a way to raise the huge amount of money needed to build the rocket. "The BFR will not only be used for Mars missions. It will be used for everything from launching satellites into space to transporting goods to the International Space Station, and even for transporting people from one part of the world to another.
wow...This is one of best story...
