A radome is a structural, weatherproof enclosure that protects a radar antenna. The radome is constructed of material transparent to radio waves. Radomes protect the antenna from weather and conceal antenna electronic equipment from view. They also protect nearby personnel from being accidentally struck by quickly rotating antennas.
The Satellite Control Network (SCN), operated by the United States Space Force's Space Delta 6, provides support for the operation, control, and maintenance of a variety of United States Department of Defense and some non-DoD satellites. This involves continual execution of Telemetry, Tracking, and Commanding (TT&C) operations. In addition, the SCN provides prelaunch checkout and simulation, launch support, and early orbit support while satellites are in initial or transfer orbits and require maneuvering to their final orbit. The SCN provides tracking data to help maintain the catalog of space objects and distributes various data such as satellite ephemeris, almanacs, and other information. It was previously known as the Air Force Satellite Control Network (AFSCN) while under Air Force Space Command's 50th Network Operations Group.
USNS Kingsport (T-AG-164) was built as SS Kingsport Victory, a United States Maritime Commission VC2-S-AP3 (Victory) type cargo ship. During the closing days of World War II the ship was operated by the American Hawaiian Steamship Company under an agreement with the War Shipping Administration. After a period of layup the ship was operated as USAT Kingsport Victory by the Army under bareboat charter effective 8 July 1948. When Army transports were transferred to the Navy's Military Sea Transportation Service the ship continued as USNS Kingsport Victory (T-AK-239), a cargo transport. On 14 November 1961, after conversion into the first satellite communication ship, the ship was renamed Kingsport, reclassified as a general auxiliary, and operated as USNS Kingsport (T-AG-164).
Andover Earth Station was one of the first satellite earth stations, located at Andover in the US state of Maine. It was built by AT&T in 1961 to communicate with the Telstar 1 satellite, the first direct relay communications satellite. It provided the first experimental satellite telephone and television service between North America and Europe. It was also used with the Relay satellite. The giant horn was dismantled in the mid 1980s along with the visitor center.
TOPEX/Poseidon was a joint satellite altimeter mission between NASA, the U.S. space agency; and CNES, the French space agency, to map ocean surface topography. Launched on August 10, 1992, it was the first major oceanographic research satellite. TOPEX/Poseidon helped revolutionize oceanography by providing data previously impossible to obtain. Oceanographer Walter Munk described TOPEX/Poseidon as "the most successful ocean experiment of all time." A malfunction ended normal satellite operations in January 2006.

Islam in the Indian Ocean was established by Muslim sea merchants well before the European discovery of Seychelles. However, unlike in other island countries such as the Comoros or the Maldives, there were no permanent inhabitants in Seychelles until the French settlement in 1770. Today, the Muslim population of the islands is reported to be approximately 1.1%, roughly 900 people. Many of its island neighbours in the southern Indian Ocean, including the Comoros, Maldives, and Zanzibar, have a much larger Muslim influence because of their settlement by Muslims before European colonization. Mauritius also has a much higher Muslim population due to the importation of labour from British India on a scale not seen in Seychelles. The government of Seychelles allows 15 minutes of religious broadcasting every Friday for the Muslim community.
Mount Hebo Air Force Station is a closed United States Air Force General Surveillance Radar station. It is located 5.2 miles (8.4 km) east-southeast of Hebo, Oregon, located at the top of 3,154-foot (961 m) Mount Hebo. It was closed in 1980.

Telstar is the name of various communications satellites. The first two Telstar satellites were experimental and nearly identical. Telstar 1 launched on top of a Thor-Delta rocket on July 10, 1962. It successfully relayed through space the first television pictures, telephone calls, and telegraph images, and provided the first live transatlantic television feed. Telstar 2 was launched May 7, 1963. Telstar 1 and 2—though no longer functional—still orbit the Earth.
Svalbard Satellite Station or SvalSat is a satellite ground station located on Platåberget near Longyearbyen in Svalbard, Norway. Opened in 1997, it is operated by Kongsberg Satellite Services (KSAT), a joint venture between Kongsberg Defence & Aerospace and the Norwegian Space Centre (NSC). SvalSat and KSAT's Troll Satellite Station (TrollSat) in Antarctica are the only ground stations that can see a low altitude polar orbiting satellite on every revolution as the Earth rotates. As of 2021, the facility consists of 100 multi-mission and customer-dedicated antennas which operate in the C, L, S, X and K bands. The station provides ground services to more satellites than any other facility in the world.
The Waihopai Station is a secure communication facility, located near Blenheim, run by New Zealand's Government Communications Security Bureau. The station started operating in 1989, and collects data that is then shared with New Zealand's allies.
