In 2011, SEI was named the 39th fastest-growing engineering firm in the United States according to the 2011 Inc. 500/5000 list. [4] SpaceWorks received the 2015 Georgia Small Business of the Year Award from the Georgia Chapter of the National Defense Industries Association on February 8, 2016. [5]
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.

13 May 1998 – HGS-1, a communications satellite operated at the time by Hughes Global Services Inc., becomes the first commercial spacecraft to visit the Moon, after flying to within 6,200 km of the lunar surface on a free return trajectory to salvage it from an unusable orbit. [13] [14]
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) .

First satellite in orbit. [5] USSR 4 October 1957 Earth: Sputnik 2: First animal in orbit, Laika, a dog. USSR 3 November 1957 Earth: Vanguard 1: Oldest satellite still in orbit, in addition to its upper launch stage. Expected to stay in orbit 240 years. Ceased transmission in May 1964.

Visiona on Friday revealed for the first time images obtained by a nanosatellite it launched last year, the VCUB1, Brazil's first locally designed Earth observation and data collection satellite.
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 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.
