                        Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

                      Descending Toward Asteroid Bennu

    Visualization Studio; Data: [6]NASA, [7]U. Arizona, CSA, [8]York U.,

   Explanation: What would it be like to land on an asteroid? Although no
   human has yet done it, [9]NASA's robotic [10]OSIRIS-REx [11]spacecraft
   is scheduled to attempt to touch the surface of asteroid [12]101955
   Bennu next week. The goal is to [13]collect a sample from the
   [14]nearby [15]minor planet for return to Earth for a detailed analysis
   in 2023. The [16]featured video shows what it looks like to descend
   toward the 500-meter diamond-shaped asteroid, based on a digital map of
   [17]Bennu's rocky surface constructed from image and surface data taken
   by [18]OSIRIS-REx over the past 1.5 years. [19]The video begins by
   showing a rapidly [20]spinning Bennu -- much faster than its real
   rotation period of 4.3 hours. After the rotation stops, the virtual
   camera drops you down to just above the [21]rugged surface and circles
   a house-sized rock outcrop [22]named Simurgh, with the flatter outcrop
   Roc visible behind it. If the [23]return sample reaches Earth
   successfully, it will be [24]scrutinized for [25]organic compounds that
   might have seeded a [26]young Earth, rare or unusual elements and
   minerals, and clues about the [27]early history of our [28]Solar
   System.
