New Horizons Kuiper Belt Extended Mission (KEM)

Following the success of the Pluto flyby, and with a fully operational and healthy spacecraft and payload, the New Horizons project was approved for its first extended mission: a 5-year long Kuiper Belt Extended Mission (KEM). KEM extends spacecraft exploration of the Kuiper Belt out to a distance of 50 AU, which the spacecraft will reach in early 2021. The main objective of KEM is an extensive study of the Kuiper Belt environment, observing numerous Kuiper Belt Objects (KBOs) and Centaurs in unique ways, and making the first close flyby of the KBO 486958 2014 MU69 (Arrokoth). The close flyby of MU69 occurred on January 1, 2019, and the data are now on the way to the Earth. The mission also delivers pre-flyby and post-flyby cruise data for all instruments.

The SBN is the lead PDS node to archive the New Horizons mission data. Here is the current version of the NH Data Management Plan. The original DMAP is also available as a PDF file.
