The distance from Earth to Mars fluctuates between approximately 35 million mi (56 million km) and 63 million mi (101 million km). In 1999, NASA's Mars Polar Lander, on a mission to analyze soil samples, made the long journey to the Red Planet only to fail to re-establish communications following its entry into Mars's atmosphere. After the lander was declared lost, an investigation determined that it likely crashed onto the Martian surface. How long did it take the lander to reach Mars?
