Space launch market competition is the manifestation of market forces in the launch service provider business. In particular it is the trend of competitive dynamics among payload transport capabilities at diverse prices having a greater influence on launch purchasing than the traditional political considerations of country of manufacture or the national entity using, regulating or licensing the launch service.
Following the advent of spaceflight technology in the late 1950s, space launch services came into being, exclusively by national programs. Later in the 20th century commercial operators became important customers of launch providers. International competition for the communications satellite payload subset of the launch market was increasingly influenced by commercial considerations. However, even during this period, for both commercial- and government-entity-launched commsats, the launch service providers for these payloads used launch vehicles built to government specifications, and with state-provided development funding exclusively.
In the early 2010s, five decades after humans first developed spaceflight technology, privately-developed launch vehicle systems and space launch service offerings emerged. Companies now faced economic incentives rather than the principally political incentives of the earlier decades. The space launch business experienced a dramatic lowering of per-unit prices along with the addition of entirely new capabilities, bringing about a new phase of competition in the space launch market.
In the early decades of the Space Age—1950s–2000s—the government space agencies of the Soviet Union and the United States pioneered space technology. This was augmented by collaboration with affiliated design bureaus in the USSR and contracts with commercial companies in the US. All rocket designs were built explicitly for government purposes. The European Space Agency (ESA) was formed in 1975, largely following the same model of space technology development.

Commercial use of space is the provision of goods or services of commercial value by using equipment sent into Earth orbit or outer space. This phenomenon – aka Space Economy (or New Space Economy) – is accelerating cross-sector innovation processes combining the most advanced space and digital technologies to develop a broad portfolio of space-based services.
Falcon 9 Full Thrust (also known as Falcon 9 v1.2, with variants Block 1 to Block 5) is a partially reusable medium-lift launch vehicle, designed and manufactured by SpaceX. Designed in 2014–2015, Falcon 9 Full Thrust began launch operations in December 2015. As of , Falcon 9 Full Thrust had performed launches without any failures. Based on the Lewis point estimate of reliability, this rocket is the most reliable orbital launch vehicle currently in operation.
vignette|Photo d'une mission Starlink (fournisseur d'accès à Internet par satellite appartenant à la société SpaceX) L'industrie spatiale est la composante de l'industrie spécialisée dans le secteur spatial. Elle se distingue du commerce spatial en ce qu'elle concerne la fabrication de tout ou partie d'un élément d'un système spatial : véhicule spatial, tel que satellite artificiel, lanceur, etc. Elle ne se confond pas non plus avec la fabrication dans l'espace, qui ne recouvre qu'une partie de l'industrie spatiale.

The hands, our silent performers in daily life, face overwhelming challenges when neurological impairments disrupt the simple tasks that compose our daily symphony. This thesis unveils a comprehensive framework for the objective monitoring of upper-limb re ...
This paper aims to discuss the past, evolution, and new perspectives in crowd simulation. Many work have been produced and published in this area that was launched approximately 30 years ago. In this paper, we re-visited the main aspects of the area, presenting the periods and evolution we had in the past. In addition, we also discuss the present and possible trends for the future.
CubeSats are a type of small satellites (< 500 kg) that weigh several kilograms and consist of multiple Units (U) measuring 100 × 100 × 113.5 mm3. CubeSats emerged as a low-cost alternative to conventional large satellites, and have since demonstrated capa ...
