API VERSION: 1.2 API SOURCE: NASA/JPL Horizons API ******************************************************************************* Revised: Sep 01, 2026 New Horizons Spacecraft -98 http://pluto.jhuapl.edu/index.php NOTE: The trajectory here now uses the plu060 post-encounter Pluto system reconstruction (Brozovic & Jacobson, "Post-new-horizons Orbits and Masses for the Satellites of Pluto", AJ, 2024). When objects -98 (spacecraft) or 2486958 (TNO target) are used as target or coordinate centers, the trajectories listed below are used to derive relative positions.

Arrokoth (2014 MU69) flyby @ 05:33 UTC, 3500 km from center) Mission Objectives: * Map surface composition of Pluto and Charon * Characterize geology and morphology of Pluto and Charon * Characterize the neutral atmosphere of Pluto and its escape rate * Search for an atmosphere around Charon * Map surface temperatures on Pluto and Charon * Search for rings and additional satellites around Pluto * Conduct similar investigations of one or more Kuiper Belt Objects Spacecraft: 1025 lbs (465 kg), 8 feet wide (2.5 m), RTG powered Concatenated spacecraft trajectory (from NH navigation, KinetX, tracking data cut-off July 20, 2026 19:11:55 TDB). USAGE NOTES: 1) To produce Horizons output relative to the Arrokoth (2014 MU69) flight-project target trajectory, specify coordinate center "@ 2486958" or "@ Arrokoth". 2) The reconstructed post Arrokoth-flyby target-body trajectory solution used is from "NavSBE_2014MU69_od159" File Start (TDB) Stop (TDB) ---------------------------------------- ----------------- ----------------- nh_pred_20060119_20070101_od021 2006-Jan-19 19:52 2006-Dec-31 23:58 nh_ref_20060119_20150925_v04 2007-Dec-31 23:58 2007-Mar-19 00:00 98_pred_20070319_20150101_od070 2007-Mar-19 00:00 2012-May-01 13:47 98_pred_20120501_20160913_od117 2012-May-01 13:47 2014-Dec-08 05:13 nh_recon_pluto_od122_v01 2014-Dec-08 05:13 2015-Sep-27 06:13 nh_recon_arrokoth_od147_v01 2015-Sep-27 06:13 2019-Feb-07 00:00 nh_pred_alleph_od151 2019-Feb-07 00:00 2021-Oct-01 00:00 98_pred_20211001_20500101_od165_v2 2021-Oct-01 00:00 2024-Jun-05 05:58 98_pred_20240605_20500101_od166 2024-Jun-05 05:58 2050-Jan-01 00:00 *******************************************************************************
