| Abstract: | We summarise the scientific and technological aspects of the Search for Anomalous Gravitation using Atomic Sensors (SAGAS)
project, submitted to ESA in June 2007 in response to the Cosmic Vision 2015–2025 call for proposals. The proposed mission
aims at flying highly sensitive atomic sensors (optical clock, cold atom accelerometer, optical link) on a Solar System escape
trajectory in the 2020 to 2030 time-frame. SAGAS has numerous science objectives in fundamental physics and Solar System science,
for example numerous tests of general relativity and the exploration of the Kuiper belt. The combination of highly sensitive
atomic sensors and of the laser link well adapted for large distances will allow measurements with unprecedented accuracy
and on scales never reached before. We present the proposed mission in some detail, with particular emphasis on the science
goals and associated measurements and technologies. |
