On the basis of previous ground-based and fly-by information, we knew that Titan's atmosphere was mainly nitrogen, with some methane, but its temperature and pressure profiles were poorly constrained because of uncertainties in the detailed composition. The extent of atmospheric electricity ('lightning') was also hitherto unknown. Here we report the(More)
The entry, descent and landing of ExoMars offer a rare (once-permission) opportunity to perform in situ investigation of the martian environment over a wide altitude range. We present an initial assessment of the atmospheric science that can be performed using sensors of the Entry, Descent and Landing System (EDLS), over and above the expected engineering(More)
The surface of Saturn's largest satellite--Titan--is largely obscured by an optically thick atmospheric haze, and so its nature has been the subject of considerable speculation and discussion. The Huygens probe entered Titan's atmosphere on 14 January 2005 and descended to the surface using a parachute system. Here we report measurements made just above and(More)
The Surface Science Package (SSP) consists of nine independent subsystems with the primary aim of characterising Titan's surface at the end of Huygens' descent through Titan's atmosphere in late 2004. In addition, many useful atmospheric measurements will be made during the descent phase. Seven of the subsystems are mounted inside or on the lower rim of a(More)
In May 2014, the Rosetta spacecraft is scheduled to rendezvous with the comet Churyumov-Gerasimenko ('67P'). One of the instruments on board the 'Lander' which will descend on to the surface of the comet is a miniaturised GC/MS system that incorporates an ion trap mass spectrometer, specially developed for isotope ratio analysis. This article describes the(More)

Several network monitoring frameworks have been successfully deployed in various network domains, but they typically expose proprietary interfaces and feature poor interoperability. In addition, frameworks either focus on end-to-end or on domain edge-to-edge measurements. Consequently, they can only address a partial spectrum of Grid performance(More)
The Jovian system is the subject of study for the Jupiter Icy Moon Explorer (JUICE), an ESA mission which is planned to launch in 2022. The scientific payload is designed for both characterisation of the magnetosphere and radiation environment local to the spacecraft, as well as remote characterisation of Jupiter and its satellites. A key instrument on(More)
