SERT-1
Sign in to saveAlso known as SERT I
SERT-1 (Space Electric Rocket Test) was a NASA probe used to test electrostatic ion thruster design and was built by NASA's Lewis Research Center (now NASA Glenn). SERT-1 was the first spacecraft to utilize ion engine design. It was launched on July 20, 1964 on a Scout rocket. It carried two electric propulsion engines; of the two, the first, an electron-bombardment ion engine ("Kaufman ion thruster") was run for a total of 31 minutes and 16 seconds. This was the first time that an ion engine of any type had been operated in space, and demonstrated that the neutralizer worked as predicted. (A

SERT-1 was the first spacecraft to utilize ion engine design. It was launched on July 20, 1964 on a Scout rocket.

This was the first time that an ion engine of any type had been operated in space, and demonstrated that the neutralizer worked as predicted. (A second thruster, of a different type, failed to operate.)
The test was followed by the SERT-II probe, launched into a 1000-km-high polar orbit on February 3, 1970, which demonstrated two mercury thrusters operating for 2011 hrs and 3781 hrs in space. Up to 300 thruster restarts were demonstrated.
