Cram the asteroid sample into the space capsule and return to Earth



Scientists said Thursday that after losing some precious trophies, NASA spacecraft more than 200 million miles squeezed the asteroid sample into a capsule and returned to Earth.

After some of the collected rubble leaked into space last week, the flight controller increased the speed of critical operations.

On October 20, the Osiris-Rex spacecraft collected pebbles and other asteroid Bennu, briefly touched the ground with its robotic arm and sucked away the contents. Collecting so much (estimated to be worth hundreds of grams), the rocks were wedged into the edge of the container and blocked the container, allowing some samples to escape.

Anything left did not leave Bennu until March when the asteroid and Earth were properly aligned. The sample will arrive here in 2023, which is seven years after the launch of Osiris-Rex from Cape Canaveral.

This is the first time the United States has carried out an asteroid sampling mission. Japan has completed two missions on other space rocks, and the latest batch is expected to arrive in December.

It is believed that Bennu, orbiting the sun, is rich in carbon and can preserve well-preserved building components in the solar system. Scientists say these residues can help explain how the planets of our solar system formed billions of years ago, and how life on Earth formed. They said that if the rock of the end of the world sails towards us, the sample can also help us improve the odds.

Bennu-a black round rock larger than the Empire State Building in New York, may be dangerously close to the earth by the end of the next decade. The probability of strike is 1

in 2700. The good news is that when it hits a fist, it will not destroy the planet.
