Suppose that the mars orbiter was to have established orbit at 155 km and that one group of engineers specified this distance as 1.55 × 105 m. suppose further that a second group of engineers programmed the orbiter to go to 1.55 × 105 ft. what was the difference in kilometers between the two altitudes? how low did the probe go?
