Cygnus is an expendable American cargo spacecraft used for International Space Station (ISS) logistics missions. Cygnus was developed by Orbital Sciences Corporation, partially funded by NASA under the agency's Commercial Orbital Transportation Services (COTS) program. To create Cygnus, Orbital paired the Multi-Purpose Logistics Module, built ...
Kenwood TS-820S. The Kenwood TS-820S is a model of amateur radio transceiver produced primarily by the Kenwood Corporation from the late 1970s into the 1980s; some were produced by Trio Electronics before Kenwood's 1986 name change). The transceiver's predecessor was the TS-520, which began production a year earlier.
Cygnus NG-20 is the ninth Cygnus mission under the Commercial Resupply Services-2 contract. Production and integration of Cygnus spacecraft were performed in Dulles, Virginia. The Cygnus service module is mated with the pressurized cargo module at the launch site, and mission operations are conducted from control centers in Dulles, Virginia and ...
Shuttle Amateur Radio Experiment. The Shuttle Amateur Radio Experiment (SAREX), later called the Space Amateur Radio Experiment, was a program that promoted and supported the use of amateur ("ham") radio by astronauts in low Earth orbit aboard the United States Space Shuttle to communicate with other amateur radio stations around the world.
The portion of the nebula resembling the north-east of North America is known as the Cygnus Wall. This region exhibits the most concentrated star formation. At optical wavelengths, the North America Nebula and the Pelican Nebula (IC 5070) appear distinct as they are separated by the silhouette of the dark band of interstellar dust L935. The ...
The Cygnus Loop (radio source W78, or Sharpless 103) is a large supernova remnant (SNR) in the constellation Cygnus, an emission nebula measuring nearly 3° across. [1] Some arcs of the loop, known collectively as the Veil Nebula or Cirrus Nebula, emit in the visible electromagnetic range. [1] Radio, infrared, and X-ray images reveal the ...
Cygnus A (3C 405) is a radio galaxy, one of the strongest radio sources in the sky. A concentrated radio source in Cygnus was discovered by Grote Reber in 1939. In 1946 Stanley Hey and his colleague James Phillips identified that the source scintillated rapidly, and must therefore be a compact object. [4]
The AN/PRC-148 Multiband Inter/Intra Team Radio ( MBITR) is the most widely fielded handheld multiband, tactical software-defined radio, used by NATO forces around the world. [1] [2] The radio is built by Thales Communications, a subsidiary of the France-based Thales Group. [3] The designation AN/PRC translates to Army/Navy Portable Radio used ...
