Two intriguing investigations -- One flight-proven spacecraft


103P on 2010-11-02

Image of 103P/Hartley taken 2010.11.02 by DI S/C and marked with directional pointers.

Caption: This EPOXI mission image of comet 103P/Hartley 2 was taken 2 days from Encounter (E-2d) using the Medium Resolution Instrument (MRI) and a clear filter. Science team co-Investigator Dr. Lucy McFadden combined four successive one-minute exposures to make this single image. The mid-exposure time was 2010/11/02 09:22 UTC. The comet was 1.06 AU from the Sun and 0.02 AU (2.3 million km) from the spacecraft.
