By 2007 it had become the most successful American direct-broadcast television service.
The Discovery program was begun by NASA in the early 1990s as the planetary counterpart to the Explorer program.
Long-Duration Lunar Base (Russian abbreviation). Soon after the beginning of the L3 project studies work also began on a lunar base to follow the initial single cosmonaut lunar landing. These studies were undertaken by Korolev's OKB-1 with Chief Designer Vladimir Pavlovich Barmin's GSKB SpetsMash (State Union Design Bureau of Special Machine-Building) as principal subcontractor. The project was known to SpetsMash as the 'Long-term Lunar Base' (DLB) and to OKB-1 as 'Zvezda'. Consideration was given to using the same elements in expeditions to other planets. Under the DLB studies SpetsMash defined purposes of the base, the principles of its construction, phases of its deployment and composition of its scientific and support equipment.
The first CORONA photos in August 1960 convinced authorities that knowledge of cloud cover over Russia was necessary and could be obtained only via satellite. Since the civilian TIROS program could not yet meet the requirement, the Director, National Reconnaissance Office authorized an 'interim' effort - the Defense Meteorological Satellite Program. The satellite series continued to be updated and served into the 21st Century.
DS ('Dnepropetrovsk Sputnik') were small satellites built by Yangel's OKB-586 / KB Yuzhnoye in the Ukraine for launch by the same KB's Kosmos launch vehicles. They were used for a wide range of military and scientific research and component proving tests.

After the N1-launched Zvezda project was cancelled, the new head of NPO Energia, Glushko, still considered the establishment of a moon base to be a primary goal for his country. While the Americans had achieved the first moon landing, it was known that all moon flights after Apollo 17 had been cancelled. There existed an opportunity, through establishment of a permanent moon base, to steal the lead in the space race once again. Furthermore, analysis of the results of the previous unmanned and manned indicated that the moon was suited for a variety of 'special investigations', and that a permanent lunar expeditionary complex (LEK) would be required to accomplish this.
The amazing story of rocket development in China is given in the milestones below.
Soviet lunar probe series. Lunas were the first manmade objects to attain of escape velocity; to impact on the moon; to photograph the far side of the moon; to soft land on the moon; to retrieve and return lunar surface samples to the earth; and to deploy a lunar rover on the moon's surface.

Malaysian communications satellite project.
Mercury was America's first man-in-space project. Setting the precedent for the later Gemini, Apollo, and Shuttle programs, any capsule configuration proposed by the contractors was acceptable as long as it was the one NASA's Langley facility, and in particular, Max Faget, had developed. McDonnell, at that time a renegade contractor of innovative Navy fighters that had a history of problems in service, received the contract. The capsule had to be as small as possible to match the payload capability of America's first ICBM, the Atlas, which would be used for orbital missions. The resulting design was less than a third of the weight of the Russian Vostok spacecraft, and more limited as a result.
The Mir space station was the last remnant of the once mighty Soviet space programme. It was built to last only five years, and was to have been composed of modules launched by Proton and Buran/Energia launch vehicles. These modules were derived from those originally designed by Chelomei in the 1960's for the Almaz military station programme. As the Soviet Union collapsed Mir stayed in orbit, but the final modules were years late and could only be completed with American financial assistance. Kept flying over a decade beyond its rated life, Mir proved a source of pride to the Russian people and proved the ability of their cosmonauts and engineers to improvise and keep operations going despite all manner of challenges and mishaps.

Military communications satellite network.
The Navaho intercontinental cruise missile project was begun just after World War II, at a time when the US Army Air Force considered ballistic missiles to be technically impractical. The Navaho required a large liquid propellant rocket engine to get its Mach 3 ramjet up to ignition speed. This engine, derived with German assistance from that of the V-2, provided the basis for the rockets that would later take Americans into space.
The Navstar GPS (Global Positioning System) program was a joint service effort directed by the United States Department of Defence. Navstar GPS is a space-based radio-positioning system nominally consisting of a 24-satellite constellation that provides navigation and timing information to military and civilian users worldwide. In addition to the satellites, the system consists of a worldwide satellite control network and GPS receiver units that acquire the satellite's signals and translate them into position information. Originally envisioned as primarily a military system, GPS was found to have a wide variety of civilian applications, many of them never conceived by the original system's designers.

Investigation of ultra-high-energy cosmic particles.
Ranger was originally to be a program of five unmanned lunar crasher spacecraft, intended to quickly obtain information on the lunar surface. The scientific objective would be to acquire and transmit a number of images of the lunar surface prior to impact, and to obtain data from a survivable package incorporating a lunar seismometer. The resulting spacecraft was much too ambitious for its period. After five consecutive failures, a simpler, picture-return-only spacecraft made three successful flights, returning the first closeup pictures of the lunar surface years behind schedule.

The world's first space station, developed in one year by the Soviet Union on the basis of Chelomei's Almaz station, in an attempt to upstage the American Skylab after the loss of the moon landing race to the Americans.
Mishin was authorised in December 1973 to build an improved design DOS-5 version of the Salyut station using Almaz facilities. Mishin's bureau borrowed the two docking port configuration of Chelomei's Almaz OPS-2 This station's second docking port would allow rotation of crews and resupply/refueling using unmanned Progress spacecraft.
Due to cancellation of the Almaz military station, and delays in the Mir project, the decision was taken in the late 1970's to fly the back-up to DOS-5 / Salyut 6. This was launched as Salyut 7 in 1982. The opportunity was still taken to fly 'guest cosmonauts' from friendly countries on short visits to the stations, although emphasis was placed on military experiments. Salyut 7 was able to conduct significant military experiments thanks to the greatly increased volume and payload of the TKS modules diverted from the Almaz programme that docked with the station.

Military store-dump communications satellite network. The commercial version of GRU Strela-3 military store-dump satellite are designated Gonets-D1. They were to be deployed in a constellation of 12 satellites (2 planes of 6) between 1996 and 1998. Each satellite has a single simultaneous earth-space and space-earth channel. On-board storage is 12 Mbits of data, with a transmission rate of 2.4 kbit/sec. Two preproduction test spacecraft of slightly different configuration called 'Gonets-D' were flown.
The Space Transportation System (Space Shuttle) was conceived originally as a completely reusable system that would provide cheap, routine access to space and replace all American and civilian military launch vehicles. Crippled by technological overreach, political compromise, and budget limitations, it instead ended up costing more than the expendable rockets it was to have replaced. STS sucked the money out of all other NASA projects for half a century. The military abandoned its use after the Challenger shuttle explosion in the 1980's.

The Voskhods were adaptations of the single place Vostok spacecraft meant to conduct flights with up to three crew and for space walks in advance of US Gemini program. Work on the 3KV and 3KD versions of the basic Vostok spacecraft began with the decree issued on 13 April 1964. In order to accommodate more than one crew, the seats were mounted perpendicular to the Vostok ejection seat position, so the crew had to crane their necks to read instruments, still mounted in their original orientation. The Elburs soft landing system replaced the ejection seat and allowed the crew to stay in the capsule. It consisted of probes that dangled from the parachute lines. Contact with the earth triggered a solid rocket engine in the parachute which resulted in a zero velocity landing.
World's first manned spacecraft, it was later developed into the Voskhod, and numerous versions of Zenit recoverable reconnaisance, materials, and biological research satellites which remained in service into the 21st Century.
The satellites, act as space repeaters capable of receiving transmissions from earth stations and retransmitting them to other earth stations in Canada. The antenna coverage of the satellite provides the capability of serving virtually all of Canada.
The WorldSpace project, led by Ethiopian-born Noah Samara, was intended to empower the developing world by providing improved access to information. Its three satellites, Afristar, Asiastar, and Ameristar, were to broadcast digital radio to less developed countries. Small hand-held radios could pick up the 24 to 96 radio channels available on the three L-band beams broadcast by each satellite. On-board processing allows variable bit rates to provide audio quality ranging from monophonic to CD digital. Broadcasters would send their programs to the satellite with a small X-band ground station.
X-15 rocket-powered manned aircraft project set records for altitude and speed, and reached the edge of space.
The X-Prize competition was an attempt to promote commercial civilian spaceflight in a manner similar to the prizes handed out in the early days of aviation. Ten million dollars was to go to the first team to fly a vehicle capable of launching three people into space (defined as an altitude of 100 km in a suborbital trajectory), twice in a two-week period. The vehicle had to be 90% reusable by dry mass. For purposes of the two flights, the competition accepted flight by one person and ballast equivalent to two others at 90 kg per passenger. The flights had to be completed before the end of 2005.
