The Int-Ball, also known as the JEM Internal Ball Camera, is a series of experimental, autonomous, self-propelled, and maneuverable ball cameras, deployed in the Japanese KibÅ module of the International Space Station. The devices are intended to perform some of the photo-video documentation tasks aboard the ISS, reducing the workload of the ...
The International Space Station's main source of energy is from the four large U.S.-made photovoltaic arrays currently on the station, sometimes referred to as the Solar Array Wings (SAW). The first pair of arrays are attached to the P6 truss segment, which was launched and installed on top of Z1 in late 2000 during STS-97 .
When the Space Shuttle was in service on missions to the International Space Station, the beta angle of the space station's orbit was a crucial consideration; periods referred to as "beta cutout", [2] during which the shuttle could not safely be launched to the ISS, were a direct result of the beta angle of the space station at those times ...
A spacecraft's attitude must typically be stabilized and controlled for a variety of reasons. It is often needed so that the spacecraft high-gain antenna may be accurately pointed to Earth for communications, so that onboard experiments may accomplish precise pointing for accurate collection and subsequent interpretation of data, so that the heating and cooling effects of sunlight and shadow ...
NASA personnel handle a single Control Moment Gyroscope for the International Space Station. The ISS employs a total of four CMGs, mounted on Z1 truss [16] as primary actuating devices during normal flight mode operation. The objective of the CMG flight control system is to hold the space station at a fixed attitude relative to the surface of ...
The Harmony node was added in 2007 as part of an expansion of the International Space Station. The maneuver will begin at 6:35 a.m. EDT with undocking the spacecraft from the Harmony module's ...
Second, NASA considers the present space station, the International Space Station (ISS), to be valuable as a zero gravity laboratory, and its current microgravity environment was a conscious choice. [8] In the 2010s, NASA explored plans for a Nautilus X centrifuge demonstration project. If flown, this would add a centrifuge sleep quarters ...
