NASA’s OSIRIS Is Reaching Close To Destination of Astroid Bennu
NASA’s satellite OSIRIS, is about to reach Asteroid Bennu, after covering 1.2 Billion Miles on December 3rd 2018. It was launched in September 2016.
It is the first ever mission of #NASA to reach a asteroid, collect a sample and then delevir it back to earth. This is a enormous task and and would be amazing achievement.
But story is not as simple as going there and coming back. The #satellite will spend a whole one and half year moving and measuring the #asteroid, mapping and data collection to find a apt place for collecting data, and then a whole lot of time tonreach back to earth.
On monday it would simply arrive at the sattelite, with the help of pre programmed manouvers to reach the satellite.
#Bennu was discovered in 1999 and is the smallest planetary body that any spacecraft has ever orbited. It is 1,650 feet wide, which is slightly larger than the Empire State Building. Bennu travels at an average speed of 63,000 mph around the sun and has the most well-understood orbit of any asteroid.
The asteroid is expected to reach back earth in september 2023. The asteroid has behaved well but still they have safe backup plans for there satellites. They have enough room for wrong duration or power of engine fire. In there words they have lot of wiggle room
