The UCL-made ‘structural-thermal model’ of the ExoMars PanCam instrument for the joint ESA-Roscosmos (Russian space agency) 2018 rover mission leaves UCL Mullard Space Science Laboratory (MSSL) today for Airbus UK in Stevenage. This is the first of several steps on the way to Mars - in 2016, UCL will deliver engineering- and flight models. The flight model will be the actual instrument which travels to Mars where it will identify promising targets for the mission.

Scientists have found the first direct evidence for explosive releases of energy in Saturn's magnetic bubble using data from the Cassini spacecraft, a joint mission between NASA, the European Space Agency, and the Italian Space Agency. The research is reported in the journal Nature Physics.

Ions from Comet 67P – early Rosetta results and increasing activity

Publication date:

Comet 67P and Lithium release comparison. From Coates et al. (2015)

As a comet nears the Sun, its icy nucleus heats, and neutral water and other gas molecules sublime, carrying ice and dust grains away also. The gas ionizes in sunlight, producing pickup ions. In a new paper, Andrew Coates and colleagues look at the early pickup process at 67P using data from the Rosetta Plasma Consortium (RPC) particle instruments. They compare the results to what was learned with the AMPTE and Giotto missions 30 years ago. The trajectory of Rosetta, the first spacecraft to fly with a comet at different distances to the Sun, is ideal for this. They discuss an elegant momentum balance seen between the new-born pickup ions and the solar wind.

Planetary group student organises Sample Space Science Week at MSSL for sixth formers

Publication date:


MSSL has just finished its second annual work experience week for sixth formers. Adi Ramani, one of the sixth formers taking part, explains enthusiastically: “It was an amazing week. I don’t think anything was lacking. It is the perfect experience for anyone wanting to pursue Physics or Engineering.”

Titan's atmosphere even more Earth-like than previously thought

Publication date:


Scientists at UCL have observed how a widespread polar wind is driving gas from the atmosphere of Saturn’s moon Titan. The team analysed data gathered over seven years by the NASA/ESA Cassini probe, and found that the interactions between Titan’s atmosphere, and the solar magnetic field and radiation, create a wind of hydrocarbons and nitriles being blown away from the top of its atmosphere into space. This is very similar to the wind observed coming from the Earth’s polar regions.

Venus is slowly losing its atmosphere

Two new papers on ionospheric photoelectrons in the tail of Venus are about to be published in Planetary and Space Science, led by UCL-MSSL scientists. They show that Venus is losing 300kg of its atmosphere per day.

Planetary Space Weather

Publication date:

In an article just published in Astronomy and Astrophysics Reviews, Jean Lilensten (IPAG, Grenoble), Andrew Coates (UCL-MSSL) and co-authors discuss the emergence of a new interdisciplinary topic - planetary space weather.

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

Publication date:


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.

Calculated charging state for the Cassini spacecraft

Dr. Gethyn Lewis will attend a consortium meeting of the Spacecraft Plasma Interaction Network of Europe (SPINE) at the European Space Agency's space research and technology centre (ESTEC) in the Netherlands, from 5 - 7 March 2012. The SPINE consortium aims to share resources and coordinate efforts to understand and model the interaction of spacecraft with their space plasma environments, including spacecraft charging. Dr. Lewis has been involved in modelling work using tools (Spacecraft Plasma Interaction System - SPIS) developed by the SPINE consortium to understand the charging of the Cassini spacecraft in orbit around Saturn.

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 work was featured on BBC News Online and is also the feature of a science nugget on the planetary science group website.
