 NOTE (2022-Jul-13):
  The Earth return/encounter trajectory over 2020-Dec-05 to Dec 10 was updated
  to a more accurate reconstruction provided by JAXA.

 BACKGROUND
  Hayabusa 2 is an asteroid sample return mission designed and operated by
  the Japanese space agency (JAXA). It was launched December 03, 2014 @ 04:22 
  UTC from the Tanegashima LA-Y site (Japan) using a H-IIA launch vehicle.

  After arrival at the target asteroid, 162173 Ryugu (1999 JU3), a separate 
  copper projectile impacted the surface at 2 km/s and created a 10 m wide
  crater, exposing the sub-surface material which was sampled and returned 
  to Earth.
