Planetary Science

The Planetary Science Group at MSSL is a leading research group studying planetary systems across the Solar System and beyond. Our science themes are planetary magnetospheres, moon interactions, surfaces and comets. We produce scientific instruments for international space exploration missions, such as the Cassini mission to Saturn, and then analyse the information which comes back from those instruments. We are analysing data from some of the Solar System's most interesting scientific targets, including Saturn and its moons Titan, Enceladus and Rhea, Mars, Venus and comets. The group is also heavily involved in future missions to Mars, Jupiter and other Solar System bodies. Previous missions include Beagle 2 and the Giotto mission to comets Halley and Grigg-Skjellerup. We work closely with the MSSL Space Plasma Physics and Imaging groups and the UCL Department of Physics and Astronomy, and are part of the Centre for Planetary Sciences at UCL/Birkbeck.

ExoMars landing sites narrowed down – and PanCam appears on BBC News

The first landing site selection workshop for the Esa-Roscosmos ExoMars rover was held on 26-28 March at ESAC near Madrid. Prof Andrew Coates of the Planetary Science Group attended the meeting, as Principal Investigator of the PanCam instrument on the rover. MSSL leads the international PanCam team which includes hardware from Germany and Switzerland, with important contributions from Austria, as well as the UK. PanCam includes a pair of wide angle cameras (WACs) for stereo imaging and a High Resolution Camera (HRC) for zoom capability. PanCam provides geological and atmospheric context for the mission.

Rover Trial

The week of 7-12 October saw an ambitious test of a prototype ExoMars Rover in the Atacama Desert in Chile, including an emulator of the MSSL-led PanCam instrument. The SAFER trial was controlled from the remote operations centre at the Space Catapult Centre, Harwell attended by Andrew Griffiths and Andrew Coates. Harwell. For more information: More...

Titan's leaking atmosphere

Saturn’s enigmatic moon Titan is of special interest to scientists due to many of its Earth-like features such as lakes, a methane cycle similar to the water (hydrological) cycle on Earth and large organic molecules in its atmosphere. Titan is the only moon in the solar system with a substantial atmosphere and it is larger than the planet Mercury. More...

Mapping Saturn's magnetosphere

When walking or driving somewhere new most people would take a map or a GPS device to find their way around. Planetary scientists usually make maps of the surfaces of planetary bodies to understand surface features. For the most part, the magnetospheres (space environments) of the planets are invisible. We have to use instruments that detect particles and magnetic fields to find our way around, like using senses of taste, smell and touch to understand where we are inside a magnetosphere. More...

Dione's thin oxygen exosphere

Dione is a moon of Saturn, discovered in 1684 by the Italian astronomer Giovanni Cassini. Over 300 years later, planetary scientists including Andrew Coates and Geraint Jones from MSSL-UCL, have discovered that Dione has a weak exosphere near its surface (at planets with denser atmospheres, the exosphere is the outermost layer of its atmosphere). This exosphere is very very thin, about a million billionth of the Earth's atmospheric density. The work shows that the exosphere contains molecular oxygen - the same form of oxygen as in Earth's atmosphere. This gives us important information about how the atmosphere is produced. More...

Counting electrons in space

Space isn't really a empty. In reality it's filled with particles that can be measured by instruments on spacecraft. But there aren't that many of them so special techniques need to be used to work out the density and temperature of the particles surrounding the planets, and our spacecraft.

Electrified ice from Saturn's moon Enceladus

During the Cassini spacecraft’s first encounter with Saturn’s 500km-wide moon Enceladus, clear indications were detected by the spacecraft’s magnetometer that the way that this body was interacting with Saturn’s magnetosphere was highly unusual. Further observations in 2005 showed that the moon was expelling gas and dust from its south polar region.
