Asteroid Bennu Mystery: NASA is very active in space exploration and there is a continuous campaign on its behalf. Sometimes on Mars, sometimes on the moon, or for other information related to space, NASA keeps sending vehicles. In this episode, he landed the OSIRIS-REx vehicle on the surface of the asteroid Bennu. Ever since this vehicle landed on the surface of Bennu, it has been sending shocking information to the scientist. Scientists are also surprised to see them. Let us know what are those scientists who are getting surprised on this planet.
Cracks in rocks come here in 10 thousand years
According to the report, data sent from the Osaras Rex vehicle showed that the heat of the Sun is higher on this asteroid than on Earth. The cracks on the rocks here occur only in 10,000 to 100,000 years. Marco Delbo, a senior scientist at the Université Cte d’Azur France, said 10,000 years may be a very long time for normal life to hear, but geologically it is too short a time. They were surprised to learn how a rock could break off and re-form on asteroids so quickly. However, this happens due to rapid changes in temperature.
the very short day-night cycle
He told that much more interesting information has been received about Benu. For example, every 4.3 hours there is a cycle of day and night. The temperature of Bennu reaches around 127 °C during the day, while it goes down to minus 23 °C at night. Due to such a rapid change in temperature, such an effect is being seen on the rocks.
The sample will come to earth by 2023
NASA scientists were currently studying the image and other information sent by the vehicle. Now in about a week, an attempt will be made to find out whether this vehicle was successful in taking more samples from there or will have to be tried again. Scientists claim that if it is successful, then in the year 2023, this vehicle will return to Earth with a sample. It took about four and a half hours for the vehicle to reach the surface from the orbit of Bennu.
