ESA Science & Technology - STE-QUEST
The Space-Time Explorer and QUantum Equivalence Principle Space Test (STE-QUEST) was a candidate mission for the M3 launch opportunity in ESA's Cosmic Vision programme. The mission was 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. In February 2014 the PLATO mission was selected for the M3 launch opportunity.
21 October 2013The five M3-candidate missions (EChO, LOFT, MarcoPolo-R, PLATO, STE-QUEST) were presented to the scientific community on 21 January 2014, in Paris, France. The presentations given at this event are available to download now.
1 February 2013The 2013 STE-QUEST workshop will be held at ESTEC, The Netherlands, from 22-23 May 2013. The scope of the workshop is to present and discuss with the scientific community the STE-QUEST science case and the progress achieved in the frame of the mission and instruments studies.
Announcement of Opportunity for the provision of scientific payload including SGS elements for the M3 mission candidates
24 September 2012Proposals are solicited for the scientific payload, including Science Ground Segment (SGS) elements, of the M3 candidate missions EChO, LOFT, MarcoPolo-R, and STE-QUEST. The deadline for submission of proposals is 30 November 2012, 12:00 CET.
18 December 2013Reference: 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...
