Today’s the day for the Mars InSight lander’s touchdown on the Red Planet, and NASA is pulling out all the stops to let us in on the action.
This is the first Mars landing to take place since the Curiosity rover was lowered onto the rocky terrain of Gusev Crater more than six years ago. And in the final hours of InSight’s nearly seven-month, 300 million-mile-cruise, the two robots are having quite a conversation on Twitter. (There’s even an in-joke over “sol,” which is NASA’s term for a Martian day.)
