In situ measurements of the physical characteristics of Titan's environment
The temperature and density profiles, as determined by the Huygens Atmospheric Structure Instrument (HASI), from an altitude of 1,400 km down to the surface were higher than expected and the extent of atmospheric electricity was also hitherto unknown. Expand
Dust measurements in the coma of comet 67P/Churyumov-Gerasimenko inbound to the Sun
The largest orbiting clumps are meter-sized, confirming the dust/gas ratio of 3 inferred at perihelion from models of dust comae and trails. Expand
Ultraviolet radiation on the surface of Mars and the Beagle 2 UV sensor
Abstract In this paper a simple radiative transfer model for the transmission of UV to the surface of Mars is presented for the wavelength range 190– 410 nm . The model accounts for the variableExpand
Density and Charge of Pristine Fluffy Particles from Comet 67P/Churyumov-Gerasimenko
The Grain Impact Analyzer and Dust Accumulator (GIADA) instrument on board ESA’s Rosetta mission is constraining the origin of the dust particles detected within the coma of comet 67Expand
Evolution of the Dust Size Distribution of Comet 67P/Churyumov-Gerasimenko from 2.2. AU to Perihelion
The Rosetta probe, orbiting Jupiter-family comet 67P/Churyumov–Gerasimenko, has been detecting individual dust particles of mass larger than 10−10 kg by means of the GIADA dust collector and theExpand
GIADA: shining a light on the monitoring of the comet dust production from the nucleus of 67P/Churyumov-Gerasimenko
During the period between 15 September 2014 and 4 February 2015, the Rosetta spacecraft accomplished the circular orbit phase around the nucleus of comet 67P/Churyumov-Gerasimenko (67P). The GrainExpand
Broadband infrared photometry of comet Hale-Bopp with ISOPHOT ?
Comet Hale-Bopp was observed ve times with ISOPHOT, the photometer on board ESA's Infrared Space Observatory (ISO) between 4.6 and 2.8 AU. Each time, broadband photometry was performed using 4Expand
Dust density and mass distribution near comet Halley from Giotto observations
The dust impact detection system (DIDSY) carried by the Giotto spacecraft has measured the density and mass spectrum (in the range 10−20–10−8 kg) of the dust near comet Halley. Profiles of the dustExpand
Hypervelocity impact studies using the 2 MV Van de Graaff accelerator and two-stage light gas gun of the University of Kent at Canterbury
The hypervelocity impact facilities of the University of Kent are described. They comprise a 2 MV Van de Graaff accelerator for the electrostatic acceleration of dust particles (mass and velocities )Expand
Convective vortices on Mars: a reanalysis of Viking Lander 2 meteorological data, sols 1–60
Dust devil data from Mars is limited by a lack of data relating to diurnal dust devil behaviour. Previous work looking at the Viking Lander meteorological data highlighted seasonal changes inExpand
