13 Nov 2007 | | Abstract: | The Solar System Odyssey mission uses modern-day high-precision experimental
techniques to answer some of the important questions on the laws of fundamental
physics which determine dynamics in the solar system. It could lead to a major
discovery by using readily available technologies and could be flown early
within the Cosmic Vision time frame. The mission proposes to perform a set of
precision gravitation experiments from the vicinity of Earth to the deep Solar
System far beyond the orbit of known planets: verification of gravity in the
deep Solar System, measurement of Eddington’s parameter, investigation on
fly-by anomaly, mapping of gravity field in the outer solar system.
The Odyssey mission focuses its efforts on the challenge of designing a deep
space mission within the cost of 300Meuros. This challenge restricts the main
mission design choices (launcher, energy and payload options) and trade-offs in
science goals. The payload definition emphasises demonstrated technology, with
non gravitational forces measured by an accelerometer upgraded from an existing
qualified design, and the probe followed by Doppler tracking and ranging built
up on existing radio science instruments.
In the baseline concept, the main spacecraft will fly beyond the Saturn orbit
(up to 13 AU), with several fly-by, allowing the achievement of the first three
scientific objectives. After the last fly-by, a radio-beacon is released and
continues the mission up to at least 50 AU, with the extension of the deep
space gravity experiment to larger distances and with achievement of the last
scientific objective of the outer Solar System gravity mapping. | | Source: | arXiv, 0711.2007 | | Services: | Forum | Review | PDF | Favorites | |
