Systems
Genesis II features a number of improvements over the first pathfinder that was launched. In addition to the standard guidance control systems used on Genesis I, it has reaction wheel assemblies and a precision measurement system, which are used to affect the spacecraft's rotation rate and angular momentum without expending fuel. It carries 22 cameras (nine more (69pc) than the 13 on Genesis I) for photographing and filming cargo and ship conditions both inside and out. Some of these are on articulated platforms, and one wireless camera will be capable of additional exterior shots. Instead of the single-tank inflation system used on the first craft, Genesis II employs multiple tanks for added reliability and to allow for more finely tuned gas control. Additional layers have been added to the outer shield for increased protection and thermal management. Finally, the on-board sensor suite has been enhanced with additional sensors for pressure, temperature, attitude control, and radiation detection, which will help determine the impact of the orbital environment on the integrity of shipboard systems.

Famous quotes containing the word systems:
“Before anything else, we need a new age of Enlightenment. Our present political systems must relinquish their claims on truth, justice and freedom and have to replace them with the search for truth, justice, freedom and reason.”
—Friedrich Dürrenmatt (1921–1990)
“What avails it that you are a Christian, if you are not purer than the heathen, if you deny yourself no more, if you are not more religious? I know of many systems of religion esteemed heathenish whose precepts fill the reader with shame, and provoke him to new endeavors, though it be to the performance of rites merely.”
—Henry David Thoreau (1817–1862)
“People stress the violence. That’s the smallest part of it. Football is brutal only from a distance. In the middle of it there’s a calm, a tranquility. The players accept pain. There’s a sense of order even at the end of a running play with bodies stewn everywhere. When the systems interlock, there’s a satisfaction to the game that can’t be duplicated. There’s a harmony.”
—Don Delillo (b. 1926)
