Interplanetary communications systems are being developed in plans to colonize Mars. I first covered Google's InterPlanetary Internet Protocols in 2011, here. Delay-tolerant network protocols must cope with huge distances between our planet and a future Martian settlement. On 9 October 2015, NASA released its plan for a manned journey to Mars, including a stated need for IPFS development:
This networking requirement for space exploration will potentially establish a permanent Internet, which I have discussed - coming from other sectors - here. On 18 March 2016, The Daily Mail reported that NASA plans to develop nuclear-powered rockets to travel to Mars, following a similar statement from the Russians in January 2016. With a nuclear rocket, spacecraft could reach the Red Planet in six weeks. The only problem is finding the money."Currently, Mars robotic rovers have data rates around two million bits per second, using a relay, such as the Mars Reconnaissance Orbiter. The ISS data rate is 300 million bits per second, two orders of magnitude faster. Future human Mars missions may need up to a billion bits per second at 1,000 times greater range than ISS, requiring laser communications to reduce weight and power. In addition, disruption and error-tolerant interplanetary networking and improved navigation capabilities are required to ensure accurate trajectories and precision landing."
