Еще про космос

Не так давно, прошла новость о том, что американцы собираются возвращаться на Луну.
Потом планируют “посетить” Марс.
И, вот — программу Орион потихоньку “сворачивают”. Нет денег.
The launch abort system, mounted on top of the Orion crew module, centers around three solid propellant rocket motors: an abort motor, an attitude control motor; and a jettison motor. Successful tests of both the abort and jettison motors were completed in 2008. The attitude control motor consists of a solid propellant gas generator, with eight proportional valves equally spaced around the outside of the 32-inch diameter motor. Together, the valves can exert up to 7,000 pounds of steering force to the vehicle in any direction upon command from the crew module.
“Controllable solid rockets have only recently begun seeing application in spacecraft, and the ACM delivers an order of magnitude greater thrust than any of those systems,” said Rivers. “It represents a significant technical advancement in controllable solid propulsion.”
