Track code TD-4 Abstract: Space communication is the receiving, sending and processing of information with space as a medium. The communications system for direct-to-earth communication consists of a satellite in orbit around Mars, over the Mars settlement, one in orbit around the sun, and ground stations on Earth in order to get their data. The satellite over the Mars settlement is an areostationary satellite, the Mars equivalent of a geostationary satellite. It is always in the same place in the sky on Mars, receiving data from the settlement and transmitting it to Earth. On Earth the data is received by ground stations using large satellite dishes. This has enabled almost 24/7 communication, which gets interrupted only when Mars is in between the satellite and the Earth. This issue can be solved by placing a second satellite in an orbit around the sun. It will follow the orbit same as that of Earth but it trails 60 degrees behind it in the ‘ …...more

Track code TD-4 Abstract: Space communication is the receiving, sending and processing of information with space as a medium. The communications system for direct-to-earth communication consists of a satellite in orbit around Mars, over the Mars settlement, one in orbit around the sun, and ground stations on Earth in order to get their data. The satellite over the Mars settlement is an areostationary satellite, the Mars equivalent of a geostationary satellite. It is always in the same place in the sky on Mars, receiving data from the settlement and transmitting it to Earth. On Earth the data is received by ground stations using large satellite dishes. This has enabled almost 24/7 communication, which gets interrupted only when Mars is in between the satellite and the Earth. This issue can be solved by placing a second satellite in an orbit around the sun. It will follow the orbit same as that of Earth but it trails 60 degrees behind it in the ‘L5 Lagrangian point’ of the Sun-Earth system. With this second satellite, when Mars is in between the areostationary satellite and the Earth, the signal can be relayed by the second satellite. This second communications satellite can also be used to relay signals during the period when the Sun is exactly in between Mars and the Earth. This occultation occurs every 26 months and lasts about six weeks. However, when the Sun is between Mars and the Earth and at the same time Mars is in between the areosynchronous satellite and the second satellite, we will have no contact with Mars for about two hours. Fortunately this situation is rare and occurs only when it is after midnight on Mars. From the 24th Annual International Mars Society Convention, held as a Virtual Convention worldwide on the Internet from October 14-17, 2021. The four-day International Mars Society Convention, held every year since 1998, brings together leading scientists, engineers, aerospace industry representatives, government policymakers and journalists to talk about the latest scientific discoveries, technological advances and political-economic developments that could help pave the way for a human mission to the planet Mars. Conference Papers and some presentations will be available on www.MarsPapers.org For more information on the Mars Society, visit our website at www.MarsSociety.org #MarsSociety #MarsSocCon2021
