Pre-Launch Activities

The pre-launch period covers everything from initial mission design to all stages of building and testing the rover, its spacecraft and its launch vehicle prior to liftoff from Earth. It requires meticulous attention to detail and years of exertion to get everything right for a successful, on-time launch. While engineers work on building and testing, scientists at universities and research institutions throughout the United States and the world plan their instrument observations and deciding how to make the best use of the rover's powerful capabilities.
