A review of the two possible Kuiper belt objects on deck for New Horizons

After Pluto, Where Will NASA’s New Horizons Go?.


  • 2014 MT69, about 37 miles wide but requires the smallest course correction from Pluto, and
  • 2014 MT70, about 47 miles wide, but will use more fuel to get to.

“We can only go to one of these, so we have to make the decision. MT69 is the front-runner because it’s lower Delta-v (change in velocity). Engineers love that. On the other hand, they kind of hate that it’s dimmer because on approach we might end up using more fuel for final (course) corrections,” he said.

The final choice will be made in August with a course correction made sometime around October.
