Now that the 'boop' has been completed (with spectacular success!), we'll move the discussion to here for subsequent mission events.

I've read about some other proposals for Apophis missions, arriving before the Earth encounter and escorting it to watch for changes both on the surface and from nearby (the views at closest approach would be spectacular, too!). But a spacecraft already launched has so many advantages.
Crossing fingers for approval! It's interesting that they could find no other close encounters in the next 8 years but Apophis. Something about the orbital mechanics being special? |

Something about the orbital mechanics being special? There would be value in closeup imaging of Apophis before its close encounter so that OSIRIS-REx can look for changes caused by the close encounter with Earth, potentially with a cubesat spacecraft. Also, OSIRIS-REx lacks some standard remote sensing composition instruments such as a gamma-ray spectrometer. (No need for those instruments with sample being returned to Earth.) There was a conference last year about Apophis and possible missions (including the potential OSIRIS-REx rendevous linked above). See Session 5 for the mission concepts.
