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:
“Our little systems have their day;
They have their day and cease to be:
They are but broken lights of thee,
And thou, O Lord, art more than they.”
—Alfred Tennyson (1809–1892)
“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)
“The geometry of landscape and situation seems to create its own systems of time, the sense of a dynamic element which is cinematising the events of the canvas, translating a posture or ceremony into dynamic terms. The greatest movie of the 20th century is the Mona Lisa, just as the greatest novel is Gray’s Anatomy.”
—J.G. (James Graham)
