  1. Why is there so little water left on Mars?

    Publishing date:

    June 24, 2021

    Mars is known for its thin atmosphere, where CO2 dominates and provides most of the atmospheric mass and pressure. In fact, the pressure is similar to that in the Earth’s stratosphere, which is a layer of the atmosphere, at more than 30km above the surface.

  3. Glacier melting: untangling local from global

    Publishing date:

    May 12, 2021

    An international team led by the LEGOS space geophysics and oceanography research laboratory has measured the evolution of all the world’s glaciers over 20 years. On average, they are losing 267 billion tonnes in ice mass a year, a cumulative loss of 4% in just 20 years. The authors confirm this phenomenon is accelerating globally as temperatures rise and explains certain slowdowns observed locally.

  10. SpaceBlower: a rocket to combat space debris

    Publishing date:

    October 8, 2020

    SpaceBlower is a light suborbital rocket designed to eject a cloud of particles into the path of large non-manoeuvrable space debris. Its goal is to avoid collisions likely to generate thousands more debris fragments and thus to keep satellites and their orbits safe. Space Blower is a preliminary project initiated and funded by CNES and its partner Bertin Technologies (now CT France). Christophe Bonnal, senior expert at CNES’s Launch Vehicles Directorate, outlines what this project is aiming to accomplish.
