The probe is on a mission to collect fragments that scientists hope will help unravel the origins of our solar system but hit a snag after it picked up too big of a sample.
Bennu was chosen by NASA for its carbon-rich character, thought to have held on to the building blocks of the solar system.
after travelling for four years, OSIRIS-REx will touch down on a site chosen by NASA, called Nightingale, a rocky area that is 16 meters in diameter.
Both asteroids are small fragments re-accumulated to form an aggregate body and may have formed from the same original shattered parent body.
NASA’s OSIRIS-REx spacecraft gets extra time to prepare for it long-awaited touchdown on asteroid Bennu
The spacecraft will attempt its first sample collection on 20 October and is equipped to do it three times if necessary.
The researchers applied their method to Apophis and Bennu, two near-Earth asteroids that are constantly flying-by Earth.
The collection of samples is slated for 2020, with the spacecraft expected to return by September 2023.
The Osiris-Rex spacecraft revealed the asteroid which is 70 million miles from Earth is covered with boulders.
Asteroid Bennu's rotation period is getting shorter by roughly one second every 100 years.
The picture was taken days before the NASA probe zoomed in to the asteroid's orbit on New Year’s Eve.
After studying Bennu for a year, OSIRIS-REx will give it a 'gentle high-five' in 2020 for a sample.
Scientists think Bennu is a leftover from the beginning of the solar system 4.5 billion years ago.
We targeted Bennu precisely because we thought it had water-bearing minerals: OSIRIS-REx mission lead.
OSIRIS-Rex could uncover a means of mining asteroids for precious resources like metals & water.
The NASA mission will help scientists investigate how planets formed and how life began.
OSIRIS-REx is expected to return with samples collected from the near-Earth asteroid Bennu in 2023.
The last of its maneuvers, scheduled for 12 November, will adjust the spacecraft's trajectory to arrive at Bennu.
Communications with mission control on a Mars missions would be delayed by up to 22 minutes.
The mission aims to bring back the biggest sample of asteroid ever, roughly 60 grams.
The report says that NASA's Planetary Defense Coordination Office is responsible to detect incoming asteroids and Comets close to the Earths orbit.
