Molniya orbit: A semi-synchronous variation of a Tundra orbit. For Earth this means an orbital period of just under 12 hours. Such a satellite spends most of its time over two designated areas of the planet. An inclination of 63.4° is normally used to keep the perigee shift small. [15]
A highly elliptical orbit (HEO) is an elliptic orbit with high eccentricity, usually referring to one around Earth.Examples of inclined HEO orbits include Molniya orbits, named after the Molniya Soviet communication satellites which used them, and Tundra orbits.
The Molniya-M (Blok-ML) was scheduled to be the last variant to fly, with two launches of Molniya spacecraft scheduled to occur in 2008; however, they were cancelled in light of the launch failure in 2005, in favour of the Meridian spacecraft.
The article is organized into two tables: the first contains a list of currently active and under-development launcher families, while the second contains a list of retired launcher families. The related article " Comparison of orbital launch systems " lists each individual launcher system within any given launcher family, categorized by its ...
