PIA00641: Multispectral Slice of APXS


Multispectral Slice of APXS

Caption:

Portions of Sojourner's Alpha Proton X-Ray Spectrometer (APXS), a deployment spring, and the rock Barnacle Bill are visible in this color image. The image was taken by Sojourner's rear camera, and shows that the APXS made good contact with Barnacle Bill.

Background Info:

Mars Pathfinder is the second in NASA's Discovery program of low-cost spacecraft with highly focused science goals. The Jet Propulsion Laboratory, Pasadena, CA, developed and manages the Mars Pathfinder mission for NASA's Office of Space Science, Washington, D.C. JPL is an operating division of the California Institute of Technology (Caltech). The Imager for Mars Pathfinder (IMP) was developed by the University of Arizona Lunar and Planetary Laboratory under contract to JPL. Peter Smith is the Principal Investigator.

Photojournal note: Sojourner spent 83 days of a planned seven-day mission exploring the Martian terrain, acquiring images, and taking chemical, atmospheric and other measurements. The final data transmission received from Pathfinder was at 10:23 UTC on September 27, 1997. Although mission managers tried to restore full communications during the following five months, the successful mission was terminated on March 10, 1998.
