Space missions:

I am associated with a number of space missions and projects; some are operational, whereas others are in development or proposed.




Cluster (Co-I)

Sunjammer (PI)



Solar Orbiter (Co-I)





THEMIS (Science Team)

MMS (IDS team member)


STEREO (Science Team)



SWARM (Guest PI)    


In Flight:

CLUSTER (European Space Agency), Co-Investigator: Cluster is an ESA four spacecraft mission (launch 2000, http://sci.esa.int/cluster), designed to study the plasma physics of the Earth's magnetosphere and its interaction with the solar wind. I have worked on Cluster since its launch and I am a Co-investigator on the Magnetometer experiment (since March 2007). At the 2010 Cluster 10th anniversary meeting I was recognized as one of the 'top 10' contributing scientists.

CINEMA (National Science Foundation/ STFC), Co-investigator: CINEMA (CubeSat for Ion, Neutral, Electron and MAgnetic fields) is a CubeSat, a small satellite designed by UC Berkeley (in collaboration with Imperial College) to remotely detect and monitor the dynamics of the Earth's inner magnetosphere with application to space weather. I was part of the original proposal team, selected by NSF in October 2009. CINEMA launched on 13 September 2012, and the MAGIC magnetometer, built at Imperial College returned its first in-flight data. TRIO (Triplet Ionospheric Observatory) is an extension to CINEMA, where two further CINEMA CubeSats will be built by Kyung-Hee University (South Korea), in order to form a multi-point observatory. A fourth CINEMA CubeSat is also planned.

ARTEMIS (NASA), Co-investigator: ARTEMIS (Acceleration, Reconnection, Turbulence and Electrodynamics of Moon's Interaction with the Sun) is a mission which extracted two spacecraft from the THEMIS constellation and sent them to lunar orbit to perform cutting edge space plasma and planetary science (http://www.nasa.gov/mission_pages/artemis/). I participated in writing the ARTEMIS proposal, which was accepted in June 2008, and following extensive review, implemented in October 2009. ARTEMIS arrived in lunar orbit October 2010, and is now conducting science observations.

THEMIS (NASA), Science team member: THEMIS (Time History of Events and Macroscale Interactions during Substorms) is a Medium Class NASA Explorer mission (launch 2007, http://themis.ssl.berkeley.edu). Its goal is to understand the physics of geomagnetic substorms, a space weather effect, using a constellation of 5 spacecraft. I have worked on THEMIS since its launch, served as the THEMIS tohban, and gained extensive experience of space mission operations.

STEREO (NASA), Science team member: STEREO is a NASA two spacecraft mission (budget $460m, launch 2006, http://stereo.gsfc.nasa.gov) designed to study the Sun and solar wind. I am a member of the STEREO/WAVES radio science experiment team.

SWARM (ESA), Guest Principal Investigator: SWARM ) is a three-satellite constellation designed to study the Earth’s magnetic field which launched in late 2013. My proposal ‘A coordinated multi-point investigation of electric currents flowing in the magnetosphere and ionosphere’ was selected in February 2012 and I am a official principal investigator of the SWARM mission. The project goal is to use SWARM in conjunction with CINEMA, Cluster and THEMIS/ARTEMIS to understand the impact of magnetospheric current systems (both transient and storm-time) on the SWARM science measurements.


In Development:

Sunjammer, Principal Investigator: Sunjammer is a solar sail technology demonstrator mission. Sunjammer’s trajectory would ultimately take it into interplanetary space, beyond the first Sun-Earth Lagrange point (L1) where it would station-keep near the Sun-Earth line. Sunjammer’s prime contractor is L’Garde Inc. Sunjammer offers the prospect of providing advanced warning of interplanetary phenomena such as shocks and coronal mass ejections (CMEs). Sunjammer will carry a space weather payload, including a magnetometer (MAGIC) for which I am principal investigator. The objectives of the Sunjammer MAGIC instrument include: to perform scientific studies of the properties of the interplanetary magnetic field (and in particular the structure of events that cause significant geomagnetic activity) as well as a scientific investigation into the general usefulness of solar sail platforms for measuring magnetic fields in the near earth space environment.


SOLAR ORBITER (ESA), Co-investigator: Solar Orbiter is the first ESA M-Class mission (http://sci.esa.int/solarorbiter) and is designed to study the Sun and solar wind. Following my work on STEREO, I am a co-investigator on the Radio and Plasma Waves (RPW) experiment (PI Milan Maksimovic). I am also a co-investigator on the Magnetometer experiment (PI Tim Horbury), for which Imperial College is the PI institute.

JUICE (ESA), Co-investigator: JUICE is the first ESA L-Class mission (http://sci.esa.int/juice) and will explore Jupiter and its moons. In particular, it will eventually enter orbit around Ganymede, where the sub-surface ocean will be characterised. I am a co-investigator on the Magnetometer (J-MAG) experiment (PI Michele Dougherty), for which Imperial College is the PI institute.

MAGNETOSPHERIC MULTI-SCALE (MMS) (NASA), Interdisciplinary Science Team member: MMS is a flagship NASA four spacecraft mission (launch 2014, http://science.nasa.gov/missions/mms) whose goal is to study the fundamental nature of magnetic reconnection. I am a member of one of the three Interdisciplinary Science Teams (PI Tai Phan) whose role is to provide cutting edge science input to optimise the development, implementation, data acquisition strategy and science return of MMS.


CENTINEL (UKSA CubeSat constellation mission study), Principal Investigator: In conjunction with Satellite Services SSBV, I conducted a 3 month mission study (March – June 2012) examining how to implement a 100+ CubeSat constellation capable of studying space weather, and particularly the onset of geomagnetic storms in the magnetotail. A report was submitted to UKSA in June 2012.

AXIOM/ AXIOM-C (ESA M-Class and S-Class mission proposal), Co-investigator: AXIOM (Advanced X-ray Imaging of the Magnetosphere) is a mission proposal (PI G. Branduardi-Raymont, UCL/MSSL http://www.mssl.ucl.ac.uk/~gbr/AXIOM/index.html) submitted to ESA's Dec. 2010 M-Class announcement of opportunity. AXIOM would use solar wind charge exchange (between heavy solar wind ions and the Earth's exosphere) to image the dayside magnetosphere. I led and coordinated Imperial College's input to this proposal. Whilst this proposal was ultimately declined, a revised proposal will be submitted to the ESA S-Class opportunity in June 2012.

Alfven+, MAG Principal Investigator: Alfven+ is a mission proposal that is being developed in response to the ESA M4 announcement of opportunity (Co-PI A. Fazakerly and M. Bertomier). At Imperial College we are designing the magnetometer experiment. More information about Alfven+ can be found here http://alfvenm4.org/.

Carrington, Co-Investigator: Carrington is a design for an operational space weather mission at the L5 Sun-Earth Lagrange point. Carrington is currently in development.
