The power system for the Mars Exploration Rover includes two rechargeable batteries that provide energy for the rover when the sun is not shining, especially at night. The main source of power for each rover comes from a multi-panel solar array. Solar Turbines производит промышленные газотурбинные установки среднего размера для систем выработки электрической энергии, применения в системах газовой компрессии и системах нагнетания. These units, especially the gas compressors, are widely used in the natural gas industry as pumping units on pipelines. Mars 100 Pg — Generator Set The Mars® gas turbine has been engineered for very high reliability and durability as well as ease of maintenance.
Because of its spectacular effect on normal matter, there is not a lot of antimatter sitting around. In space, it is created in collisions of high-speed particles called cosmic rays. On Earth, it has to be created in particle accelerators, immense machines that smash atoms together. High-energy gamma rays can also make the engines radioactive by fragmenting atoms of the engine material. The lead absorbs the gamma rays and radiates lower-energy X-rays, which vaporize the nozzle material.
The NASA Institute for Advanced Concepts (NIAC) is funding a team of researchers working on a new design for an antimatter-powered spaceship that avoids this nasty side effect by producing gamma rays with much lower energy. Image right: This is an artist’s concept of an advanced positron rocket engine, called an ablative engine. There would be no radioactive particles to drift on the wind. Deliveries of this auxiliary power unit started in 1962. The Navy also had Solar adapt the Titan into a free-turbine version designated by the Navy as the T66, but this unit was never put into use. During the next decade the Solar Division introduced a number of new designs, both larger and smaller than the Saturn.
