A GTO is an intermediary orbit used to make this process more efficient. Satellite operators often use a high-thrust, low-efficiency launch vehicle to put their satellite into GTO, and then, after detaching the launch vehicle, use low-thrust, high-efficiency thrusters onboard the satellite itself to circularize its orbit (to GEO) over a longer ...
A large spacecraft such as the International Space Station can be constructed by assembling modules in orbit, or in-space propellant transfer conducted to greatly increase the delta-V capabilities of a cislunar or deep space vehicle. Distributed launch enables space missions that are not possible with single launch architectures. [13]
In 2018, the launch services sector accounted for $5.5 billion out of a total $344.5 billion "global space economy". [ 4 ] : 9 It is responsible for the ordering, conversion or construction of the carrier rocket , assembly and stacking, payload integration, and ultimately conducting the launch itself.
Space debris at geostationary orbits typically has a lower collision speed than at low Earth orbit (LEO) since all GEO satellites orbit in the same plane, altitude and speed; however, the presence of satellites in eccentric orbits allows for collisions at up to 4 km/s (14,400 km/h; 8,900 mph). Although a collision is comparatively unlikely, GEO ...
Space industry refers to economic activities related to manufacturing components that go into outer space (Earth's orbit or beyond), delivering them to those regions, and related services. [ 1 ] [ 2 ] [ 3 ] Owing to the prominence of satellite-related activities, some sources use the term satellite industry interchangeably with the term space ...

The European Ariane 5 first flew in 1996 and launched many commercial payloads to GTO. It benefited in this role by launching from Guiana Space Center, a spaceport near the equator in French territory. Ariane 5 often carried multiple payloads per launch and set records for mass to GTO delivered for commercial payloads.
In 2019, ISRO chief K. Sivan presented the features of the proposed space station for the first time, saying that the space station may weigh up to 20 tons. Three years later, in his New Year's speech delivered before retiring as chairman, Sivan stated that India's first crewed spaceflight project Gaganyaan had completed the design phase and entered into the testing phase, hinting that the ...
