How terrible it is to imagine that life on the Earth will end before we could ever think of! But yes, NASA Scientists have warned that a devastating event may tend to happen in the future. An Asteroid could possibly strike the surface of the Earth! NASA is sending a space probe to collect rock samples from the Asteroid dubbed as 'Bennu' which is heading towards our planet. It can collide with the Earth after it is dislodged by some gravitational pull and can cause gigantic, utter massive demolition. 'Bennu' can be seen every six years from the Earth, but it is predicted that in 2135 it would pass between the Earth and the Moon which would jerk the Moon's orbit and make it clash with the Earth.

Yes, the Scientists at NASA have warned that this massive collision will lead to immense suffering and death!
The collision, as the experts predict would be devastating, the sight of which can't even be visioned in the most dreadful dreams!
But The Osiris-Rex Mission, headed by the joint efforts of NASA and the University of Arizona, assures some ray of hope. There is a plan to launch an unnamed spacecraft on September 8 with an aim to reach 'Bennu' in August 2018. It will orbit the Sun for a year and will then use the Earth's gravitational field to aid it in the way to traverse 'Bennu.'
It is reported that the Osiris-Rex will spend a year before returning to the Earth. 'Bennu' is about 500m in diameter and this size Asteroid would create craters of about 7km or equivalent and an earthquake of about magnitude 7.
The picture depicts an artistic view of the Osiris-Rex at the surface of 'Bennu.' 'Bennu' is one of the darkest objects in the Solar System as it has enormous amounts of graphite and carbon on its surface and further studies on it would lead to more in-depth knowledge of the formation of the Universe and the existence of life on the Earth.
The Origins, Spectral Interpretation, Resource Identification, Security- Regolith Explorer is what is the Osiris-Rex. It is equipped with an instrument to measure the visible and near infrared light emitted and reflected from the asteroid. It will map the asteroid to find out the best sample site and help the Scientists to study light of different wavelengths.
This is the orbit of Bennu's traversal as predicted by the Scientists at NASA.
The spectrometer it is embedded with is very inexpensive, operates at about 10 watts and is designed to work as a cryogenic gadget- at very low temperatures. It has no moving parts which reduce the probability of malfunction in space. It is expected to research 'Bennu and return in September 2023. Once, the perfect spot has been found it will be fetched and returned to the surface of the Earth.
Well, we hope that the Scientists get the results that they are awaiting, and the information is useful for future predictions so that we can happily live our lives, protected from Bennu's invasion!
