Did you know that the Deep Impact Flyby Spacecraft has a new assignment? The EPOXI mission combines two exciting science investigations in an entirely new mission that re-uses the Deep Impact spacecraft. The Extrasolar Planet Observation and Characterization (EPOCh) investigation will observe stars that have known transiting giant planets. The Deep Impact Extended Investigation (DIXI) of comets observes comet 103P/Hartley 2 during a close flyby in October 2010.

Using the two images above I and Nick Howes we have compute a period of rotation of 18-20 hours.

That image taken even by Nick Howes with a 2 meter telescope permit to measure the spatial length of the main emission that result to be about 828+/- 26 km with an error of about 1 pixels.  The resolution of the images is 0.27 arcsec/pixels.
