In this tutorial, we will use GMAT to perform a finite burn for a spacecraft using an electric propulsion system. Note that targeting and design using electric propulsion is identical to chemical propulsion and we refer you to the tutorial named Target Finite Burn to Raise Apogee for targeting configuration. This tutorial focuses only on configuration and modelling using electric propulsion. On Tuesday, Ap , NASA awarded a contract to Aerojet Rocketdyne, Inc. to design and develop an advanced electric propulsion system that will significantly advance the nation’s commercial space capabilities, and enable deep space exploration missions, including the robotic portion of NASA’s Asteroid Redirect Mission (ARM) and its journey to Mars.

Solar electric propulsion (SEP) refers to the combination of solar cells and electric thrusters to propel a spacecraft through outer space. This technology has been exploited in a variety of spacecraft by the European Space Agency, the Japanese Space Agency, Indian Space Research Organisation and NASA.
SEP has a significantly higher specific impulse than normal chemical rockets, thus requiring. Get this from a library.

Solar Electric Propulsion (SEP) trajectories are shown for Mars missions between late and 1. Mission performance is presented as burn-out mass along contours of constant flight time. The Solar Electric Propulsion project is developing large solar arrays and high-power electric thrusters for an integrated in-space test-flight.
Compared with current conventional chemical propulsion systems, at launch it will weigh two times less and use four times less storage for the electricity produced, and will operate at radiation levels. Electric Propulsion Options and Trades • Benefits: • Much higher specific impulse • Arcjets – s • Hall Thrusters – – s • Ion thrusters – – 10,s • Other concepts (VASIMIR, MPD, PIT) in same range • Higher Isp results in much lower propellant mass • Trades: • Need external source of power and electronics to match to the thruster.
spacecraft propulsion. With literally hundreds of electric thrusters now operating in orbit on communications satellites, and ion and Hall thrusters both having been successfully used for primary propulsion in deep-space scientific missions, the future for electric propulsion has arrived.
An electrically-powered spacecraft propulsion system uses electrical, and possibly also magnetic fields, to change the velocity of a of these kinds of spacecraft propulsion systems work by electrically expelling propellant (reaction mass) at high speed. Electric thrusters typically use much less propellant than chemical rockets because they have a higher exhaust speed (operate.
• Solar electric propulsion allows deep-space missions to carry more cargo and use smaller launch vehicles while reducing mission costs. • The Solar Electric Propulsion project has developed solar arrays that are lighter, stronger, more compact, and less expensive than those currently available.
