Tail Probe is one of the satellites of the INTERBALL program. ... Collection of the orbital elements | ... Flight situation analysis during operations scheduling . ... Two stages of the orbital situation analysis are presented: . ... The satellites motion calculation during the flight situation analysis is based on the orbital elements, determined by the Ballistic center at KIAM RAN. The modified (by backward integration) orbital elements are usedduring the aposteriory situation analysis. ...

Different types of satellite orbits have different uses: while the synchronous orbit is best for communication satellites, Lagrangian point orbits help monitor the solar wind before it reaches Earth. A low altitude polar orbit is widely used for monitoring the Earth because each day, as the Earth rotates below it, the entire surface is covered. ... A different choice was made for MAGSAT, orbited 1979-80 to survey the Earth's own magnetic field near its surface. ...

Lunar Orbiter to the Moon (1966 - 1967) . ... Five Lunar Orbiter missions were launched in 1966 through 1967 with the purpose of mapping the lunar surface before the Apollo landings. ... The first three missions were dedicated to imaging 20 potential lunar landing sites, selected based on Earth-based observations. ... The Lunar Orbiters had an ingenious imaging system, which consisted of a dual-lens camera, a film processing unit, a readout scanner, and a film handling apparatus. ...

... xmmtrack . ... xmmtrack is an interactive IDL application that visualizes the orbit and attitude data in an ODF in the form of a 3-D animation sequence. The presented scenery includes an astronomically accurate simulation of the Earth-Sun system plus the actual and predicted trajectory of the XMM satellite on its path around the Earth. ... Please note: XMM's orbit is highly time variable and the predicted orbit will significantly deviate from the actual trajectory if the reference epochs differ. ...

... Space debris comprise the ever-increasing amount of inactive space hardware in orbit around the Earth as well as fragments of spacecraft that have broken up, exploded or otherwise become abandoned. About 50 percent of all trackable objects are due to in-orbit explosion events (about 200) or collision events (less than 10). International Year of Astronomy, Ireland National Node . ...
