Aquanauts experience communication delays


NEEMO 21 is now conducting operations under 15-minute communication time delay – including science and exploration dives! Due to the distance between Earth and Mars, communications can be between 4 and 24 minutes one-way, depending on the orientation of the planets. Aquanaut Dr. Marc O Griofa says “you are almost chasing the past, present & future all at the same time” while coordinating interactions between Mission Control and the crew. The goal is to figure the tools and protocols we need to effectively communicate under time-delayed conditions when astronauts explore Mars.
