Spaceflight is an application of astronautics to fly spacecraft into or through outer space, either with or without humans on board. Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit. Such spaceflight operates either by telerobotic or autonomous control. The more complex human spaceflight has been pursued soon after the first orbital satellites and has reached the Moon and permanent human presence in space around Earth, particularly with the use of space stations. Human spaceflight programs include the Soyuz, Shenzhou, the past Apollo Moon landing and the Space Shuttle programs, with currently the International Space Station as the main destination of human spaceflight missions while China's Tiangong Space Station is under construction.
Kosmos is a designation given to many satellites operated by the Soviet Union and subsequently Russia. Kosmos 1, the first spacecraft to be given a Kosmos designation, was launched on 16 March 1962.
The Italian Space Agency is a government agency established in 1988 to fund, regulate and coordinate space exploration activities in Italy. The agency cooperates with numerous national and international entities who are active in aerospace research and technology.
Orbital Sciences Corporation was an American company specializing in the design, manufacture and launch of small- and medium- class space and launch vehicle systems for commercial, military and other government customers. In 2014, Orbital merged with Alliant Techsystems to create a new company called Orbital ATK, Inc., which in turn was purchased by Northrop Grumman in 2018. The remnants of the former Orbital Sciences Corporation today are a subsidiary of Northrop Grumman known as Northrop Grumman Space Systems.
The Scout family of rockets were American launch vehicles designed to place small satellites into orbit around the Earth. The Scout multistage rocket was the first orbital launch vehicle to be entirely composed of solid fuel stages. It was also the only vehicle of that type until the successful launch of the Japanese Lambda 4S in 1970.
The Luigi Broglio Space Center (BSC) is an Italian-owned spaceport near Malindi, Kenya, named after its founder and Italian space pioneer Luigi Broglio. Developed in the 1960s through a partnership between the Sapienza University of Rome's Aerospace Research Centre and NASA, the BSC served as a spaceport for the launch of both Italian and international satellites (1967–1988). The center comprises a main offshore launch site, known as the San Marco platform, as well as two secondary control platforms and a communications ground station on the mainland.
Ariel was a British satellite research programme conducted between the early 1960s and 1980s. Six satellites were launched as part of the programme, starting with the first British satellite, Ariel 1, which was launched on 26 April 1962, and concluding with the launch of Ariel 6 on 2 June 1979. The launch of Ariel 1 made Britain the third country to have a satellite orbiting the Earth. The first four were devoted to studying the ionosphere, the remaining two to X-ray astronomy and cosmic-ray studies.
Ariel VI, known pre-launch as UK-6, was a British and American satellite launched in 1979 as part of the Ariel programme. It was operated by the Science Research Council, which became the Science and Engineering Research Council in 1981. Ariel VI was used for astronomical research and provided data until February 1982. It was the last Ariel satellite to be launched.
Ariel 2, also known as UK-C, was a British radio astronomy satellite, which was operated by the Science and Engineering Research Council as part of the Ariel programme. It was built in America by Westinghouse Electric, and had a mass at launch of 68 kilograms (150 lb). It was launched in 1964, and became the first satellite to be used for radio astronomy, although the Canadian satellite Alouette 1 was launched 1962 and also did similar radio astronomy observations.
Space research is scientific study carried out in outer space, and by studying outer space. From the use of space technology to the observable universe, space research is a wide research field. Earth science, materials science, biology, medicine, and physics all apply to the space research environment. The term includes scientific payloads at any altitude from deep space to low Earth orbit, extended to include sounding rocket research in the upper atmosphere, and high-altitude balloons.
Explorer 9, known as S-56A before launch, was a NASA satellite which was launched in February 1961 to study the density and composition of the upper thermosphere and lower exosphere. It was a reflight of the failed Explorer S-56 mission, and consisted of a 7 kg (15 lb), 3.66 m (12.0 ft) balloon which was deployed into a medium Earth orbit. The mission was conducted by NASA's Langley Research Center.
The San Marco programme was an Italian satellite launch programme conducted between the early 1960s and the late 1980s. The project resulted in the launch of the first Italian-built satellite, San Marco 1, on 15 December 1964. With the programme Italy became the third country in the world to operate a launch with its own crew, after the Soviet Union and the United States, and the fifth to operate its own satellites after also Canada, and the United Kingdom. San Marco was a collaboration between the Italian Space Research Commission (CRS), led by Luigi Broglio and Edoardo Amaldi, and NASA. In total 5 satellites were launched during the programme, all using American Scout rockets. The first flew from Wallops Flight Facility with the rest conducted from the San Marco Equatorial Range. The last satellite, San Marco-D/L, launched on 25 March 1988.
Notable spaceflight activities in 2017 included the maiden flight of India's Geosynchronous Satellite Launch Vehicle Mark III on 5 June and the first suborbital test of Rocket Lab's Electron rocket, inaugurating the Mahia spaceport in New Zealand. The rocket is named for its innovative Rutherford engine which feeds propellants via battery-powered electric motors instead of the usual gas generator and turbopumps.
This article documents notable spaceflight events during the year 2018. For the first time since 1990, more than 100 orbital launches were performed globally.
Orbital-1, also known as Orb-1, was the second flight of the Orbital Sciences Cygnus cargo spacecraft, its second flight to the International Space Station (ISS) and the third launch of the company's Antares launch vehicle. The mission launched on 9 January 2014 at 18:07:05 UTC.
Explorer S-56 was a NASA satellite launched on 4 December 1960, at 21:14 GMT as part of the Explorer program. The satellite was composed of a 3.66 m (12.0 ft) diameter inflatable sphere, and was intended to study the density of the upper atmosphere. The Scout X-1 rocket used to launch Explorer S-56 failed in flight, and the satellite never reached orbit.

FR-1 was the second French satellite. Planned as the first French satellite, it was launched on 6 December 1965—ten days after the actual first French satellite, Astérix—by an American Scout X-4 rocket from the Western Range at Vandenberg Air Force Base. The scientific satellite studied the composition and structure of the ionosphere, plasmasphere, and magnetosphere by measuring the propagation of very low frequency (VLF) waves and the electron density of plasma in those portions of the Earth's atmosphere. FR-1's VLF receiver operated until 26 August 1968. FR-1 remains in orbit as of November 2020.
