New Horizons extended mission target selected

Posted by Emily LakdawallaCasey Dreier on 2015/09/01 06:09 CDT | 5 comments

The New Horizons mission has formally selected its next target after Pluto: a tiny, dim, frozen world currently named 2014 MU69. The spacecraft will perform a series of four rocket firings in October and November to angle its trajectory to pass close by 2014 MU69 in early January 2019. In so doing, New Horizons will become the first flyby craft to pass by a target that was not discovered before the spacecraft launched.

The signal was received at 00:52:37 UT | 20:52:37 ET | 17:52:37 PT. As planned, New Horizons returned no images with the Phone Home downlink. But every bit of telemetry indicated that the flyby executed successfully.
