ESA selects planet-hunting PLATO mission 19 February 2014 A space-based observatory to search for planets orbiting alien stars has been selected today as ESA's third medium-class science mission. It is planned for launch by 2024. Read more
The Space-Time Explorer and QUantum Equivalence Principle Space Test (STE-QUEST) is a candidate mission for the M3 launch opportunity in ESA's Cosmic Vision programme. The mission is designed to answer a range of questions in fundamental physics by performing precision measurements with high accuracy atomic sensors. In particular, STE-QUEST would test Einstein's Equivalence Principle, which underpins the theory of General Relativity; explore the boundaries with the quantum world; and search for new fundamental constituents and interactions in the Universe.
Cosmic Vision M3 candidate missions presentation event 21 October 2013 In February 2014, the ESA SPC will decide which of five M3-candidate missions (EChO, LOFT, MarcoPolo-R, PLATO, STE-QUEST) should be carried forward to the next stage. Prior to this decision, the missions will be presented to the scientific community, on 21 January 2014, in Paris, France. The Assessment Study Reports and Technical Review Reports are available now.

STE-QUEST Preliminary Requirements Review Technical Report 18 December 2013 Reference: ESA-STEQ-RP-0001, Issue 1, Revision 1. STE-QUEST, a Space-Time Explorer and Quantum Equivalence Principle Space Test, is one of five candidate missions for the M3 launch opportunity. A Preliminary Requirements Review (PRR) of all candidate missions has been performed to review their status in support of the M3 selection. This document reports the results of the technical and programmatic review for the STE-QUEST mission candidate. Read more
STE-QUEST Mission Requirements Document 18 September 2012 Reference: SRE-PA/2011.074/RQ/MG; Issue 2, Revision 3. This document aims at providing a complete and comprehensive list of all high level mission requirements (including spacecraft and payload, launcher, ground segment and operations) necessary to achieve the science goals detailed in STE-QUEST Science Requirements Document (FPM-SA-Dc-00001).

STE-QUEST Payload Definition Document 22 June 2012 Reference: SRE-PA/2011-075/TN/PW; Issue 1, Revision 1. This document describes the Payload of STE-QUEST, a mission in the Fundamental Physics domain conceived to test to high accuracy the different aspects of the Einstein Equivalence Principle. This document derives directly from the STE-QUEST Science Requirements Document and STE-QUEST Mission Requirements Document. It also integrates elements included in the STE-QUEST proposal (and associated reference documents), the STE-QUEST CDF Study and the STE-QUEST Instruments Mid-Term Review data packages. Read more
