July: Big month for NASA
This satellite mission will examine comet composition because the impact will eject materials from the comet. The satellite is composed of two parts: the flyby satellite which has various imaging devices and the impactor which will hit the comet. It is 816 pounds and about the size of a coffee table. Hitting the comet at 23,000 mph will produce a crater on the comet and blast materials into space which the flyby unit will measure.
Below is a data figure. The left image is a visual of the comet and the right image is spectrometer readings that gives data on the chemical composition of the comet.
