The correct choice is A. The Mars Climate Orbiter met with disaster on Mars's surface because one program calculated thrust in foot-pounds while another anticipated it in newtons. The Mars Climate Orbiter, part of NASA’s Mars Surveyor '98 initiative, failed in its mission to analyze the Martian climate. Designed as a satellite to relay information for the Mars Polar Lander, after that lander malfunctioned, it was meant to continue studying Martian weather patterns. The orbiter was lost when a navigation error caused it to enter an orbit too low, leading to its destruction from atmospheric stresses. An inquiry revealed that some thrust data were computed in English units while the navigation team was using SI units.
