That Time NASA Recycled a Mars Lander

The Phoenix Mars Lander was a unique NASA mission that reused components from previous missions, including the cancelled 2001 Mars Surveyor and parts from Spirit and Opportunity. It successfully landed on Mars on May 25, 2008, using a radar system adapted from fighter jets to measure altitude and velocity. The mission aimed to search for water on Mars, and it achieved this by using a robotic arm with motors tested from previous missions. Phoenix discovered evidence of water ice and calcium carbonate in Martian soil, demonstrating NASA's ability to conduct planetary science on a budget by repurposing existing technology.
