Which word best characterizes a vehicle made for another planet? That’s exactly what NASA is asking the public with their “Name the Rover” contest. NASA plans to launch their Mars 2020 rover in July, but before it can happen, they need your help naming it.

Last year, over 28,000 students across the country submitted essays with suggested names. Now, NASA has narrowed it down to the top nine. The final names are: Clarity, Courage, Endurance, Fortitude, Ingenuity, Perseverance, Promise, Tenacity, and Vision.

NASA will use this public vote to help pick the rover's name. The official name will be announced in March.
