NASA cancelled its Mars Insight mission late last year, just three months before its scheduled launch, it wasn’t clear if the lander would ever make it to Mars. Today, that lander got a second chance and a new launch date in 2018. Insight had goal of collecting data about what’s happening in Mars’s interior.
But then, one of the lander’s vacuum-sealed instruments, a seismic monitor designed to measure tremors in the ground, started springing leaks as fast as NASA could patch them. When it popped another leak just three months before its scheduled launch to Mars, NASA had no choice but to cancel plans to launch the $525 million mission.
