After 200 years, this asteroid will hit the Earth. NASA once found water in the mysterious asteroid Bennu in the asteroid belt between Mars and Jupiter. The mission to find the bone marrow was made on the same day. It was NASA's first adventurous plan to land on an asteroid and pick up pebbles from it. That campaign was successful. NASA spacecraft is about to return after collecting samples after landing at Bennu.
‘Osiris Rex’ এই this NASA spacecraft was sent to Bennu Para in 2016. This spacecraft has understood its reality by circling around the asteroid for so many days. He sent pictures to the ground station of the world. It is almost impossible to land on the back of a rough, friendly, rugged Bennu. There is also a risk of danger in the chest of unknown asteroids. Cosmic rays, comets, meteors often hit Bennu. Its size is not that big. So all in all there was a worry. NASA chief Jim Bridenstein tweeted that all thoughts were over. NASA's historic mission is successful. The Osiris Rex returns to the back of the Bennu asteroid, picking up pebbles within the allotted time (18 seconds). His speed did not slow down when he landed on the rocky ground, nor did he have any problem in grabbing the ground. For the first time since the Apollo mission to the moon, NASA has succeeded in an adventurous mission.
Of all the asteroids around the Earth, Bennu is the largest. So there is no problem in landing the spacecraft. The distance of Bennu from the earth is 334 million kilometers. This asteroid is located in the asteroid belt between Mars and Jupiter. This asteroid belt is the address of all the asteroids in the universe. Bennu is shy again. NASA astronomers say Bennu is hiding his face in thick clouds. This cloud is made up of cosmic particles.
Astronomers say that scattered parts of different asteroids, isolated parts of comets, small cosmic particles together have formed dense clouds in the sky of Bennu. There are traces of huge meteors in the past on Bennu's chest. Comet, cosmic ray struck. This impression is still carried by this asteroid. So his soil is rough, friend. Rough back. The environment is so rough that it is difficult to land a spacecraft properly. There are various minerals scattered on the ground.

The country's educational institutions, which were closed due to the epidemic coronavirus, have indicated that they will not reopen in November. Dipu Moni.

Asked by reporters whether the educational institution could be opened in November, the education minister said, "What do you think?" In the current situation, most of the educational institutions are in the process of closing down. Since there is a concern about winter everywhere, experts say. That is why we will discuss with the National Advisory Committee on Kavid-19.
"When we think that our students, teachers and parents have no health risks or very little, maybe even risk, we can open up," he said. It is not possible for any of us to say when this will happen.
The government had earlier said that the fifth and eighth final exams would not be held due to the deadly virus. It has already been informed that the results of the eighth standard and the results of the SSC will be announced on the basis of the results of the SSC without the HSC examination. This time in the press conference on Wednesday, the education minister said, the annual examination of sixth to tenth class at secondary level will not be held this time. All students without exams will be taken to the next class.
Students will be given weekly assignments with a short syllabus of 30 days to fill the student deficit, based on which they will also be assessed. However, the impact of that assessment will not fall on their progress to the next class.
