Whereas NASA’s Jet Propulsion Laboratory (JPL), managed 
by the California Institute of Technology (Caltech), de-
signed and built the Rovers, Spirit and Opportunity; 
Whereas Cornell University led the development of advanced 
scientific instruments carried by the 2 Rovers, and con-
tinues to play a leading role in the operation of the 2 
Rovers and the processing and analysis of the images and 
other data sent back to Earth; 
Whereas the Rovers relayed over a quarter million images 
taken from the surface of Mars; 
Whereas studies conducted by the Rovers have indicated that 
early Mars was characterized by impacts, explosive volca-
noes, and subsurface water; 
Whereas each Rover has discovered geological evidence of an-
cient Martian environments where habitable conditions 
may have existed; 
Whereas the Rovers have explored over 21 kilometers of Mar-
tian terrain, climbed Martian hills, descended deep into 
large craters, survived dust storms, and endured 3 cold, 
dark Martian winters; and 
Whereas Spirit and Opportunity will have passed 5 years of 
successful operation on the surface of Mars on January 
3, 2009, and January 24, 2009, respectively, far exceed-
ing the original 90-Martian day mission requirement by 
a factor of 20, and are continuing their missions of sur-
face exploration and scientific discovery: Now therefore 
be it 
Resolved, That the House of Representatives— 
(1) commends the engineers, scientists, and 
technicians of the Jet Propulsion Laboratory and
