SUMMARY: The powerful Hubble Space Telescope was on hand to watch the collision between Deep Impact and Comet Tempel 1. Even though Hubble is one of the most sensitive telescopes available, the shroud of dust and gas surrounding Tempel 1 obscures a view of the comet's nucleus. Hubble was able to see the flash from the impact, making the comet 4 times as bright, and then an expanding fan of debris moving away from the comet.

Did this impact change the tragectory the comet travels or was it too minor?

Look at this great movie of the impact from probe's point of view

Yes, any if any two objects collide bothe their speeds are affected no matter what their sizes, but it is negligible- according to nasa the resulting change in speed of the comet was measured in millimetres/hour (its speed is into tens of thousands of mph)

It must have been quiat an impact if it obscured the view of hubble.
