Interior of Tranquility The Tranquility node during initial manufacturing. Tranquility was built within the ESA-NASA ISS bartering system. ESA committed to build and fund both Harmony and Tranquility as well as the ATV in order to use NASA ISS facilities, fly astronauts on the Shuttle and for other ISS services.
The PDS Management Council serves as the technical policy board of the PDS, and provides findings for NASA with respect to planetary science data management, ensures coordination among the nodes, guarantees responsiveness to customer needs, and monitors the appropriate uses of evolving information technologies that may make PDS tasks both more ...
The nodes were connected with InfiniBand single and double data rate (SDR and DDR) cabling with transfer speeds of up to 10 gigabits per second. The SGI Altix platform was selected due to a positive experience with Kalpana , a single-node Altix 512-CPU system built and operated by NASA and SGI and named after Columbia astronaut Kalpana Chawla ...
The NASA Deep Space Network (DSN) is a worldwide network of spacecraft communication ground segment facilities, located in the United States (California), Spain , and Australia (Canberra), that supports NASA's interplanetary spacecraft missions.
Unity has two axial and four radial Common Berthing Mechanism (CBM) ports. In addition to connecting to the Zarya module, Unity connects to the U.S. Destiny Laboratory Module (added on STS-98), the Z1 truss (an early exterior framework for the station added on STS-92), the PMA-3 (also added on STS-92), and the Quest Joint Airlock (added on STS-104).
TDRS Program Logo Location of TDRS as of March 2019 An unflown TDRS on display at the Steven F. Udvar-Hazy Center in Chantilly, Virginia.. The U.S. Tracking and Data Relay Satellite System (TDRSS, pronounced "T-driss") is a network of American communications satellites (each called a tracking and data relay satellite, TDRS) and ground stations used by NASA for space communications.
The lunar nodes are the two points where the Moon's orbital path crosses the ecliptic, the Sun's apparent yearly path on the celestial sphere.. A lunar node is either of the two orbital nodes of the Moon; that is, the two points at which the orbit of the Moon intersects the ecliptic.
Harmony is managed by NASA's Marshall Space Flight Center in Huntsville, Alabama. Its deployment expanded the Space Station, allowing it to grow from the size of a three-bedroom house, to the space equivalent of a typical five-bedroom house, once the Japanese KibÅ and European Columbus laboratories are attached.
