What will DS1 do on its mission?
The Plasma Experiment for Planetary Environments (PEPE) is one of the new instrument technologies being tested and demonstrated with the New Millennium Deep Space One mission. It is there to measure plasma (which is like energized gas) and make a three dimensional picture of plasma distributions. It also measures ions, electrons and energy in the plasma. PEPE will measure and make images of the plasma used in DS1's engine. It will also be used to learn about plasma found in space. PEPE will serve three purposes:
PEPE's measurement capabilities approach those of the a previous plasma measuring device called the Cassini Plasma Spectrometer (CAPS) instrument, but PEPE doesn't take as much raw materials to build, costs less, and was made on a much faster time table.
