In January 2006, the European Space Agency, together with the Australian National University, announced successful testing of an improved electrostatic ion engine, the Dual-Stage 4-Grid (DS4G), that showed exhaust speeds of 210 km/s, reportedly four times higher than previously achieved, allowing for a specific impulse which is four times ...
The Deep Space mission carried out a flyby of asteroid 9969 Braille and Comet Borrelly. Deep Space 1 had 178 pounds (81 kilograms) of xenon propellant, with a total impulse capability of 2.65 x10 6 Ns [5] and was capable of increasing the speed of DS1 by 7900 miles per hour (12,700 kilometers per hour, 3.58 km/s) over the course of the mission.

Rogue Space Systems announced that the satellite is equipped with an "experimental propulsion" system, referred to as a "quantum drive," developed by IVO Limited. The satellite's testing program includes a 60-day resting period post-launch to stabilize its orbit, accounting for initial perturbations such as outgassing .
Grid erosion cannot be avoided and is the major lifetime-limiting factor. Thorough grid design and material selection enable lifetimes of 20,000 hours or more. A test of the NASA Solar Technology Application Readiness (NSTAR) electrostatic ion thruster resulted in 30,472 hours (roughly 3.5 years) of continuous thrust at maximum power. Post-test ...
As a motivation, seven examples of hypothetical space drives were described at the onset of the project. [1] These included the gravity-based pitch drive, bias drive, disjunction drive and diametric drive; the Alcubierre drive; and the vacuum energy based differential sail. [13] The project then considered the mechanisms behind these drives.
The first successful demonstration of an ion engine was NASA SERT-1 (Space Electric Rocket Test) spacecraft. [19] [20] It launched on 20 July 1964 and operated for 31 minutes. [19] A follow-up mission launched on 3 February 1970, SERT-2. It carried two ion thrusters, one operated for more than five months and the other for almost three months ...
Once you have grid energy storage and home-based energy storage, the actual total energy output per year of the grid is dramatically greater than people think. Maybe it's at least double.
The IXS Enterprise as imagined by Mark Rademaker. IXS Enterprise is a conceptual interstellar superluminal spacecraft designed by NASA scientist Dr. Harold G. White, revealed at SpaceVision 2013, designed for the goal of achieving warp travel.
