Think of it as the Mars equivalent of an emergency 911 call for help. Operators of NASA’s Mars rovers have established a backup remote site in the event of a natural disaster, malfunctioning ground equipment, or even a terrorist attack to maintain critical contact with space vehicles as they near the red planet. A unique Emergency Control Center, or ECC, has been set up at Lockheed Martin Space Systems in Denver, Colorado. If a natural or human-generated event interrupted JPL operations, the ECC would assume control of the vehicles as they streak toward their Mars landings.
