With a sample of asteroid Bennu in the luggage, the NASA probe Osiris-Rex has turned back to the earth. The probe had left the Currency of Bennu on Monday, said the US space farmers with. In October, Osiris-Rex had removed a sample for the asteroids with a multi-stuncy complicated manobe – as the first US flight body of space history. This sample should now deliver the probe in September 2023 on Earth.
Hope for coarse test
How much gram dust and rich of the asteroid contains the sample, NASA researchers do not know exactly. At the manover, a breakdown happened: the lid of the collecting container had been slightly eliminated by coarse stones, so that parts of the sample could escape. The NASA ames that the minimum requirement of 60 grams of dust and bulky is filled – and probably even significantly more in the collection container.
In September 2023, Osiris-Rex should throw the sample on earth, where they should then land with the help of parachutes in the US state of Utah. Employees of NASA should then bring the sample to the Johnson Space Center in Houston in the state of Texas and distribute from there parts of them in laboratories around the world where they can be examined.
Osiris Rex (Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer) was launched in September 2016 from Cape Canaveral Space Station and arrived for about two years later at Bennu. Since then, the somewhat six meter long and 2100 kilograms of heavy probe circled the asteroids and examined him with their scientific instruments and cameras. Several times she flew back very close to him.
Maybe dangerous for the earth
The deep black Bennu, named after an ancient agypal deity, has a diameter of around 550 meters and could reach the earth in a good 150 years. Even if the impact risk is very low, NASA BENNU pays to the most dangerous known asteroids – and therefore wants to explore it very well.

In addition, scientists suffer from the approximately one billion dollar-expensive mission insights into the development of the solar system from more than 4.5 billion years ago, because asteroids are surprisingly.
