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.

Space of high Earth orbits (HEO), between medium Earth orbits (MEO) and the orbit of the Moon. A high Earth orbit is a geocentric orbit with an apogee farther than that of the geosynchronous orbit, which is 35,786 km (22,236 mi) away from Earth. [1] In this article, the non-standard abbreviation of HEO is used for high Earth orbit. [2]

NASA Earth science satellite fleet as of September 2020, planned through 2023. Earth observation satellite missions developed by the ESA as of 2019. Earth observation satellites are Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the earth. These satellites are used to monitor short-term weather ...
The previous record of people in orbit was set in May 2023, when for a brief period of time there were 17 people aboard both the International Space Station and China’s Tiangong space station.
The timeline of first Earth observation satellites shows, in chronological order, those successful Earth observation satellites, that is, Earth satellites with a program of Earth science. Sputnik 1 , while the first satellite ever launched, did not conduct Earth science.
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 ...
