17022 Huisjen           Discovered 1999 Feb. 18 by the Lowell Observatory Near-Earth Object Search at the Anderson Mesa Station.
Martin A. Huisjen (b. 1944) was the manager at Ball Aerospace and Technology Corporation for the development of all the scientific instruments on the Deep Impact spacecraft. His technical and programmatic contributions include identifying alternative readout modes for the detector in the near-infrared spectrometer.
