PROBA-3 is a dual-probe technological demonstration mission by the European Space Agency devoted to high-precision formation flying to achieve scientific coronagraphy. It is part of the series of PROBA satellites that are being used to validate new spacecraft technologies and concepts while also carrying scientific instruments.
Diagram of a typical gas turbine jet engine. Air is compressed by the compressor blades as it enters the engine, and it is mixed and burned with fuel in the combustion section. The hot exhaust gases provide forward thrust and turn the turbines which drive the compressor blades. 1. Intake 2. Low pressure compression 3. High pressure compression ...
With any current source of electrical power, chemical, nuclear or solar, the maximum amount of power that can be generated limits the amount of thrust that can be produced to a small value. [citation needed] Power generation adds significant mass to the spacecraft, and ultimately the weight of the power source limits the performance of the vehicle.

On 23 August 2023, as the lander approached the low point of its orbit, its four engines fired as a braking manoeuvre at 30 kilometres (19 mi) above the Moon's surface.
It was also used in the Ford Probe, the Ford Tempo and Mercury Topaz from 1992 to 1994 (optional, but standard in the 1992 GLS, XR5, and LTS models, respectively), [5] the Ford Aerostar and Ford Windstar minivans, and the Ford Ranger and Mazda B3000 pickup trucks. The 3.0 L Vulcan replaced Ford's 2.9 L German Cologne V6 as the base V6 in the ...
