2013 STE-QUEST Workshop


2013 STE-QUEST Workshop
22-23 May 2013
Keplerlaan 1, Noordwijk - The Netherlands

Update - 6 June 2013: The workshop presentations are now available in pdf format, through the "Scientific Programme" link from the right-hand menu.

Update - 10 May 2013: A new pdf file is available from the right-hand menu, with details of the Programme, List of Posters, Participants and the Abstracts.

Update - 1 May 2013: The deadline for submission of abstracts has been extended to 6 May.

Einstein's Theory of General Relativity is a cornerstone of modern physics. It is used to describe the flow of time in the presence of gravity; the motion of bodies, from satellites to galaxy clusters; the propagation of electromagnetic waves in the presence of massive bodies; and the dynamics of the universe as a whole.

Although very successful so far, general relativity, as well as numerous other alternative or more general theories of gravitation, are classical theories. As such, they are fundamentally incomplete as they do not include quantum effects. A theory solving this problem would represent a crucial step towards the unification of all fundamental forces of Nature. Several approaches have been proposed and are currently under investigation (e.g. string theory, quantum gravity, extra spatial dimensions) and all of them tend to lead to tiny violations of basic principles. Therefore, a full understanding of gravity will require observations or experiments able to determine the relationship between gravity and the quantum world. This topic is a prominent field of activity and includes the current studies of dark energy.

Space-Time Explorer and QUantum Equivalence Space Test (STE-QUEST) is a mission conceived to test the different aspects of the Einstein Equivalence Principle by using high-stability and high-accuracy atomic sensors. Submitted in reply to the 2010 Call for Medium-size Missions for the Cosmic Vision plan, STE-QUEST was recommended by the ESA Advisory Structure and selected for an assessment study.

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.

These web pages will be updated with more details of the workshop, such as the programme and transport information, as they become available.

The two day workshop will be held at the European Space Research and Technology Centre (ESTEC), the ESA establishment in the Netherlands, in the conference room Newton. See the "Venue" link in the right-hand menu for full details and travel information.

How to get to ESA/ESTEC

(Note: for transport between the hotels and the workshop venue please see the bus schedule in the Hotel accommodation section below.)

ESTEC is located at the southern tip of the coastal town of Noordwijk.

By car
From Amsterdam: take the A4 (direction Den Haag-Rotterdam) then at the junction follow the A44. Take the exit "Noordwijk-Voorhout", continue to Noordwijk and from there, follow the signs to "ESTEC".
From Den Haag (The Hague): take the A44 (direction Amsterdam) and exit at "Leiden" (exit 8). Follow the N206 towards Katwijk and Haarlem. Take the exit "Katwijk Noord". From there follow the signs to "ESTEC" (small white squares).

By bus
From Leiden Central station: take bus 30 or 31 to Katwijk. The journey takes about 30 minutes and the bus stops in front of the ESTEC entrance gate. Please note that these buses leave more frequently during rush-hour periods but with frequency reducing during normal hours. For the most recent schedule, please check  or

From other directions: the nearest bus stop to ESTEC is 'Katwijk, Schorpioen' (300 metres from the ESTEC entrance gate). Lines that pass here are bus 90 (from Noordwijk, Nieuw Vennep or Den Haag) and bus 385 (from Noordwijk or Den Haag - this line also passes the Leiden Transferium). For more details see the bus information links above.

By plane
From Schiphol airport, either take a taxi to ESTEC (30 min), or a train to Leiden Centraal (15 min) and then the number 30 or 31 bus (see bus directions above) (30 min). By rental car, follow the "By car" instructions as above from Amsterdam.
