Design for nanosatellite PICASSO positively assessed
12 May 2015 - To measure the ozone distribution in the stratosphere, the temperature in the mesosphere and the electron density in the ionosphere, the Belgian Institute for Space Aeronomy (BIRA-IASB) is developping the PICASSO satellite, in collaboration with VTT (Finland), Clyde-Space Ltd (UK) and the Centre Spatial de Liège (Belgium), for the European Space Agency ESA.
Just 32x10x10 cm in size, this CubeSat will use:
On 23-24 April 2015, the PICASSO mission was reviewed by ESA during a Preliminary Design Review (PDR) collocation at the European Space Research and Technology Centre (ESTEC). Both instruments (VISION and SLP) and the platform were positively assessed during a very intense questions/answers session with ESA experts from different fields.

Comet probe detects the «most wanted molecule»
March 20, 2015 - ESA’s comet probe Rosetta has for the first time ever measured nitrogen gas at a comet, providing clues to the early stages of the formation of our solar system.
The measurement was made possible thanks to the high mass resolution of the ROSINA/DFMS mass spectrometer, for which the Belgian Institute for Space Aeronomy together with imec and OIP built most of the detector assembly.
The study was led by researchers at the University of Bern and has now been published in the journal «Science».

Catching A Comet in Science Magazine
23 January 2015 - In August 2014, the European Space Agency’s Rosetta spacecraft arrived at comet 67P/Churyumov-Gerasimenko. Once in orbit, it swooped as low as 10 kilometers to get unprecedented data from the comet (and to drop off its short-lived Philae lander). Today, Science Magazine is publishing a suite of new papers detailing some of the mission’s first findings.
BIRA-IASB scientists are involved with their analyses of data coming from the ROSINA instrument that measured the coma composition of comet 67P.
These measurements show large fluctuations in composition in a heterogeneous coma that has diurnal and possibly seasonal variations in the major outgassing species:
Other new findings suggest a wide range of deuterium-to-hydrogen (D/H) ratios in the water within Jupiter family objects (based on measurements around the Jupiter family comet 67P) and preclude the idea that this reservoir is solely composed of Earth ocean–like water.
