New Horizons Pluto–Kuiper Belt mission: design and simulation of the Pluto–Charon encounter
The primary goal of the New Horizons Pluto–Kuiper Belt mission is to explore Pluto by 2020, before Pluto’s atmosphere collapses as predicted by scientists, and then explore the Kuiper Belt objects in an extended mission. The baseline mission plans to launch in January 2006, using a Jupiter gravity assist trajectory to reach Pluto. The New Horizons spacecraft will arrive at Pluto as early as 201...
متن کاملCollision Rates in the Present-day Kuiper Belt and Centaur Regions: Applications to Surface Activation and Modiication on Comets, Kuiper Belt Objects, Centaurs, and Pluto-charon Proposed Running Header: Collisions in the Edgeworth-kuiper Belt Address Editorial Correspondence To
We present results from our model of collision rates in the present-day Edgeworth-Kuiper Belt and Centaur region. We have updated previous results to allow for new estimates of the total disk population, in order to examine surface activation and modi cation time scales due to cratering impacts. We extend previous results showing that the surfaces of EdgeworthKuiper Belt objects are not primord...

متن کاملNew Horizons: NASA’s Pluto-Kuiper Belt Mission
The New Horizons (NH) mission was selected by NASA in November 2001 to conduct the first in situ reconnaissance of Pluto and the Kuiper belt. The NH spacecraft was launched on January 19, 2006, received a gravity assist from Jupiter during closest approach on February 28, 2007, and is currently heading for a flyby encounter with the Pluto system. NH will study the Pluto system for nearly seven ...
متن کاملA giant impact origin of Pluto-Charon.
Pluto and its moon, Charon, are the most prominent members of the Kuiper belt, and their existence holds clues to outer solar system formation processes. Here, hydrodynamic simulations are used to demonstrate that the formation of Pluto-Charon by means of a large collision is quite plausible. I show that such an impact probably produced an intact Charon, although it is possible that a disk of m...
