Repeat orbit: An orbit where the ground track of the satellite repeats after a period of time. Gangale orbit: a solar orbit near Mars whose period is one Martian year, but whose eccentricity and inclination both differ from that of Mars such that a relay satellite in a Gangale orbit is visible from Earth even during solar conjunction.

The list for the year 2025 and for its subsequent years may contain planned launches, but the statistics will only include past launches. For the purpose of these lists, a spaceflight is defined as any flight that crosses the Kármán line , the FAI -recognized edge of space, which is 100 kilometres (62 miles) above mean sea level (AMSL) .

This was the first time that a rocket entered orbit after launching from a privately owned and operated spaceport. China Chinese private company i-Space successfully launched its Hyperbola-1 rocket from Jiuquan Satellite Launch Center and sent several small payloads, including the CAS-7B amateur radio satellite into Earth orbit on July 25, 2019 ...
It may also refer to the time it takes a satellite orbiting a planet or moon to complete one orbit. For celestial objects in general, the orbital period is determined by a 360° revolution of one body around its primary, e.g. Earth around the Sun. Periods in astronomy are expressed in units of time, usually hours, days, or years.
The height was not only the highest humans have reached in 50 years, but also marked the highest that the SpaceX Dragon has flown to date, SpaceX said in a day one update.
Space launch market competition is the manifestation of market forces in the launch service provider business. [1] 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 ...
