  2. DORN, the French instrument on the Chang’e 6 mission

    Publishing date:

    December 18, 2019

    The lander on China’s Chang’e 6 mission will be carrying the DORN radon detection instrument with the goal of studying its outgassing from the lunar regolith and how this radioactive gas and other species like water are transported in the Moon’s exosphere. Launch is planned in 2023.

  5. 2011: Developing more accurate accelerometers

    Publishing date:

    September 20, 2011

    For the first time, a team of French physicists, supported by CNES and ESA, has succeeded in developing a vibration-resistant accelerometer. Tested in parabolic flight, the prototype was able to measure infinitesimal accelerations, which until now was only possible in the laboratory. This could pave the way for the development of portable cold atom accelerometers and thus improved positioning and geoligical prospecting systems. It could also make it possible to directly test aspects of Einstein's general theory of relativity. The results are published in the journal Nature Communications.

  6. XMM-Newton discover a new source of low energy cosmic rays

    Publishing date:

    June 29, 2012

    Thanks to XMM-Newton, a X-ray astronomy European satellite, scientists from CNRS and CEA discovered a new source of cosmic rays which are different from cosmic rays known until now. In the neighbourhood of the Arches cluster, near the Milky Way center, these particles are accelerated in the shockwave generated by the movement of thousands of young stars at the speed of about 700,000 km/h. These cosmic rays then produce a characteristic X emission while interacting with the atoms of the ambient gas.

  15. Nanoparticles detected by STEREO

    Publishing date:

    May 14, 2009

    A new type of dusts just got discovered in the interstellar medium: nanoparticles which had been accelerated up to several hundreds of kilometers per second by the solar wind-carried magnetic field. This discovery was an unexpected spin-off of the S/WAVES experiment on board the Sun orbiting STEREO probes. This experiment used a radio receptor built by the Laboratory of Space Studies and Instrumentation in Astrophysics (Observatory of Paris/LESIA).

  19. Mars: a water vapour-saturated atmosphere

    Publishing date:

    September 30, 2011

    After analysing again the data sent by the SPICAM spectrometer on board ESA's Mars Express, the Martian atmosphere turned to be water vapour-over-saturated. This surprising discovery, with major implications for the understanding of the Martian water cycle as well as for the evolution of its atmosphere, was announced in an article of the September 29th 2011 issue of Science.
