MAGNETOSPHERES

Our Space Plasma work covers a wide range of of approaches. The interests of the group include instrumentation, data analysis and theory. Each complements the others.

We want to understand the processes controlling the origins, entry, acceleration and loss of plasma in the Earth's neighborhood, and in the
magnetospheres of other Solar System planets. Some of our recent publications are available. For those who want to know more of the
context there is an online Space Plasmas textbook.




A central objective of the group is to exploit the unique opportunities offered by upcoming missions in which we have access to important data sets thanks to our active instrument building collaborations.

The ISTP Program, an international constellation of spacecraft including Cluster II, Polar, IMAGE and Geotail , together with associated
missions such as Wind, SOHO and groundbased observations, are producing a wealth of data which will transform the scope of space
physics.


These new missions will put us in an excellent position to answer major questions in Space Plasma Physics, and build on the work of our previous missions.

Studies of storms, and substorm onset and dynamics, build on our work with CRRES, while cusp and boundary layer studies are based on our experience with AMPTE. Our work includes Theory and Simulations, and interacts strongly with the Ionospheric Group at RAL, who work on EISCAT and run the World Data Centre.


We are involved in producing instruments for a number of past, present and future space missions. We aim to continually improve our range of new instrumental techniques.

Our areas of special expertise include VLSI chips, Software, Microchannel Plates, and High Voltage sets. We are involved in a number of missions for Imaging Energetic Neutral Atoms including the NASA IMAGE MIDEX mission, TWINS, a Stereo Neutral Imaging mission using Molniya orbits, and the RAPID instrument on Cluster II . We will supply the detectors on ASPERA, the Swedish led Neutral Imager on Mars Express.

 

We are extending our programs to the plasma environments of other planets, such as such as the Moon, Saturn and Mercury, and in interplanetary space.

The launch of the Cassini mission to Saturn is be an important step. We have an active planetary program. We are also currently involved in other missions to the Moon and Mars.

PLANETS - Our Program

Our planetary science program is based on a strong program of space mission instrument development, and the unique opportunities offered by the important data sets for current and upcoming missions which this gives access to. This is reinforced by data analysis, ground-based observing and theoretical studies. Each complements the others. We have a wide range of interests, in a number of the planets, in the interplanetary dust, and in extrasolar planets.

  • We want to understand the processes controlling the origins, entry, acceleration and loss of plasma in the neighbourhood of the Earth's and other Solar System planets, such as such as Mars, Mercury , and Saturn , Jupiter and their moons.
  • The Cassini mission at Saturn is an important step. At Saturn, we are also actively interested in dust distribution, dusty plasmas, and the surface of Titan itself.
  • A recent highlight is our leadership of the D-CIXS experiment on the ESA SMART-1 mission to the Moon. This X-ray fluorescent spectrometer will investigate the fundamental geophysical history of the Moon, and hence the origin of the Earth-Moon system.
  • We are also involved in the ASPERA3 experiment on Mars Express, which probes the interaction of (and erosion by) the Solar Wind and atmosphere, and hence address the question of water loss on Mars.
  • Following on from this, we will repeat the task of detector provision for ASPERA4 experiment on ESA's Venus Express, where it will investigate the interaction of the Solar Wind with the Venus ionosphere.
  • Our laboratory facilities have been used to give empirical calibration data for atmospheric and structure studies of Jupiter.
  • We have a profound interest in the emerging ares of exobiology, planetary formation and the discovery of earthlike Extrasolar Planets. The ASPERA investigations of Water loss on Mars, the SMART-1 study of Earth-Moon system formation, preparations for Beagle, and our vigorous involvement in Darwin and the exobiology forum are all part of this objective.
