In-flight performance and calibration of SPICAV SOIR onboard Venus Express.

MERCURY In-flight calibration of the PHEBUS UV instrument & Monte Carlo modelling of the hydrogen exosphere MEA SIMON WEDLUND

A unique feature of Mercury’s space environment is its strongly coupled surfaceexosphere-magnetosphere-solar wind system, which can be remotely monitored by space missions such as Mariner 10, MESSENGER and soon BepiColombo and by ground-based observatories. Mercury’s exosphere is a very complex medium with only a few species detected so far, including atomic hydrogen. H has only been detected o...

Densities and temperatures in the Venus mesosphere and lower thermosphere retrieved from SOIR on board Venus Express: Retrieval technique

First observation of the Venus UV dayglow at limb from SPICAV/VEX

Performance assessment of onboard and scene-based methods for Airborne Prism Experiment spectral characterization.

Accurate spectral calibration of airborne and spaceborne imaging spectrometers is essential for proper preprocessing and scientific exploitation of high spectral resolution measurements of the land and atmosphere. A systematic performance assessment of onboard and scene-based methods for in-flight monitoring of instrument spectral calibration is presented for the first time in this paper. Onboa...

Coordinated Hubble Space Telescope and Venus Express Observations of Venusâ€TM upper cloud deck

Hubble Space Telescope Imaging Spectrograph (HST/STIS) UV observations of Venus’ upper cloud tops were obtained between 20N and 40S latitude on December 28, 2010; January 22, 2011 and January 27, 2011 in coordination with the Venus Express (VEx) mission. The high spectral (0.27 nm) and spatial (40–60 km/pixel) resolution HST/STIS data provide the first direct and simultaneous record of the lati...
