The specific impulse, impulse bit, thrust efficiency and thrust-weight ratios of 50% helium - 50% nitrogen are 801 seconds, 6.29 μN The gases used in the thruster are pure helium, nitrogen and argon with gas mixtures of 50% helium - 50% nitrogen and 50% helium - 50% argon. Gas mixtures are tested in this research to observe any improvement in the overall performance. This research investigates the design and performance of a low-cost magnetoplasmadynamic thruster built for micro and nanosatellites. Magnetoplasmadynamic propulsion is a technology that the plasma is accelerated electromagnetically. Alternatively, magnetoplasmadynamic propulsion provides higher thrust to miniature satellites than ion thrusters without the increase in mass. The problem with ion and Hall thrusters is the low thrust-to-power ratio (30 mN/kW-50 mN/kW), and it is not enough for high-speed manoeuvres in deep-space missions. It is up to you to complete the mission successfully.Article: Design and implementation of low-power low-cost quasi steady-state magnetoplasmadynamic propulsion using Ar-He and N2-He gas mixtures Journal: International Journal of Aerospace System Science and Engineering (IJASSE) 2021 Vol.1 No.1 pp.20 - 34 Abstract: Current miniature plasma propulsion technologies use ion or Hall propulsion to provide thrust for miniature satellites. Of course all extra expenses will be charged. Furthermore there is a communication system at your command. 2 satellites - Scan Moon surface and vehicle movementĪfter a work day you have the possibility to retreat to a recovery room below the lunar surface.1 recovery vehicle - Tow surface vehicles in the event of a failure.1 drone - Scan helium concentration, vehicles and the station.6 harvesters - Extraction of raw helium from Moon dust.Several unmanned vehicles are coordinated and you only have a certain amount of time per day before the daily dose of radioactive radiation becomes too high. The game is controlled with the dashboard by either entering commands with the mouse or keyboard. The technology at your command is the latest from 1986. You are alone in the station and no one can help you. However, in order to achieve this goal, the player's physical and mental health must be kept in mind. Once the player has reached a total helium mining amount of 25 tons, the contract with the Helium Electric corporation has been fulfilled and you can count on a position in the corporation if you perform well. If you don't, your relatives will suffer, your stress level will increase, and your mental health will decrease.

The goal is to achieve the highest possible helium mining rate and you are free to decide how to manage the station.ĭepending on the amount of helium extracted, you get a daily payment to support your family and friends on Earth. Helium Electric is a hard strategy game in which the player finds himself alone in a Moon station and has the mission to extract helium. Earth’s future seemed assured, but at a very high price…. Helium Electric had found a way to mine helium on the moon and convert it to electricity on Earth. Over time, one company proved particularly successful. The Cold War became more and more a corporate struggle.

Until it came to a near standstill.Ĭorporations took control of the action and found new ways to supply the world with necessities. The story is set in the Cold War of the 1980s, in which humanity was blindly drawn into the Cold War without realizing that this insane endeavor was causing a shortage of resources.
