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.
