The ion thruster then processes the propellant and power to propel the spacecraft. The first ion thrusters did not last very long, but the ion thruster on Deep Space 1 exceeded expectations and was used more t hours during a period of over 2 years.
The ion thrusters being developed now are being designed to operate for 7 to 10 years. The very name of the T6 ion thruster sounds like something from sci-fi.
But it’s very real, and this little engine will be one of four that take the European Space Agency’s BepiColombo. BepiColombo is powered by four T6 ion engines supplied by British defence and technology company QinetiQ which are fitted to the craft’s power unit, the Mercury Transfer Module (MTM).
They work by ‘ionising’ inert xenon gas - knocking an electron off the gas atoms to give them a positive : Jack Loughran.
Ion propulsion was proved on NASA's Deep Space 1 mission, which tested it and11 other technologies while journeying to an asteroid and a comet.
Each of Dawn's three centimeter-diameter ( inch) ion thrust units is movable in two axes to allow for migration of the spacecraft's center of mass during the mission. The BepiColombo mission to mercury uses an ion thruster with a ISP of 4, seconds(41, M/s).
The same formula yields a mass ratio of The NEXIS ion thruster can achieve seconds (78, m/s) The European DS4G innovative thruster mana seconds (, m/s) exceeding the km/sec from the above question.
