But even with all of the cameras and the microphone, don’t expect an instant video feed. Those large files will take a while to transmit. Even rudimentary communications like the “heartbeat tone” take 11 minutes and 22 seconds to reach Earth at this time of year. That delay means that NASA engineers won’t have real-time communication with the craft during the infamous “seven minutes of terror,” when it must survive its descent through the martian atmosphere and land autonomously.
