Abstract

This talk will cover the Quantum Accelerometer Climate Explorer
(Q-Ace), a mission concept studied in the UK for performing
Thermosphere Meteorology.

The Q-Ace mission will consist of twelve satellites that orbit through
the upper atmosphere, where they experience the drag caused by the
density of the atmosphere. This drag is measured through a quantum
accelerometer, a cold atom interferometer. The orbit is maintained
through electric thrusters, and the satellite is stabilised in part by
aerodynamics. The drag measurements will be downloaded through the
ground segment antennas. 

The Q-Ace mission has now successfully passed the first part of a
Phase A study (preliminary mission requirements), and is now further
specifying the science applications that such a mission can perform,
this is tied to modelling of the thermosphere to create a real time
model, and near real time predictions, of the weather in the
thermosphere.

The mission concept, is to expand weather modelling into the
thermosphere, and so be in a position to monitor long term variations
in that weather. By expanding the area where weather is understood
brings an enhanced understanding of climate. 

This talk will focus on the science that the mission can perform,
which will include the results from our on-going scientific study.
