  1. Three satellites shortlisted for Earth Explorer 10

    Date de publication:

    19 Octobre 2018

    Three new satellite concepts have been selected by ESA to compete for its 10th Earth Explorer mission. The winner will join the agency’s environment and climate research programme in 2027-2028. We talk with Juliette Lambin, who heads CNES’s Earth, Environment and Climate programme, about the technical innovations the candidates are proposing and the scientific discoveries they promise.

  2. France-United States space cooperation- InSight Mars exploration mission,first tests of French SEIS seismometer successful

    Date de publication:

    5 Décembre 2018

    After the excitement and tension of its successful landing on Mars on Monday 26 November, InSight has started powering up and checking out its subsystems. The SEIS1 seismometer, supplied by CNES as lead contractor with the IPGP global physics institute in Paris as principal investigator working with teams at the French national scientific research centre CNRS, was tested out on Friday 30 November. Everything is nominal and the instrument is in great shape.

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

    Date de publication:

    24 Juin 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.

  5. SuperCam and its super sensors

    Date de publication:

    31 Mars 2021

    The French Space Agency (CNES) has reported the first images obtained on Mars using the Remote Micro-Imager (RMI) of the SuperCam instrument (the French contribution to NASA JPL PERSEVERANCE Rover) during the CNES Press Conference. The instrument provides high resolution (<70 µrad per pixel) color images for planetologists.

  6. Artemis programme: back to the Moon

    Date de publication:

    16 Octobre 2020

    NASA’s Artemis programme plans to land the first woman and the next man on the Moon in 2024, followed by an exploration/prospection phase using the Gateway as a staging outpost and ultimately the construction of a lunar base starting in 2030.

  7. SpaceBlower: a rocket to combat space debris

    Date de publication:

    8 Octobre 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.

  8. Solar storms impact Earth’s neighbourhood

    Date de publication:

    16 Décembre 2019

    Fifteen years after they were first acquired, data from the Cluster mission continue to reveal new insights into the disturbances generated by solar storms when they hit Earth’s magnetosphere. For the first time, scientists have succeeded in measuring the complexity and amplitude of these magnetic wave disturbances using data from the CIS instrument on the four Cluster satellites.

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

    Date de publication:

    18 Décembre 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.

  11. What do we know about Mars’ interior?

    Date de publication:

    26 Novembre 2018

    The first missions to reach the surface of Mars date back 40 years, but many mysteries still lie beneath its top layer of iron oxide. To delve deeper into the red planet, the InSight lander is carrying a system able to drill down to five metres and sound Mars’ surface over a radius of thousands of kilometres. Following its arrival on Mars, we talk about what we already know and what we hope to discover there with CNES’s Francis Rocard, head of Solar System Exploration programmes, and Philippe Laudet, SEIS project leader for InSight and head of the agency’s Astronomy and Astrophysics programme.

  14. Source of Saturn’s kilometric radiation revealed

    Date de publication:

    13 Novembre 2018

    Using data from the Cassini mission, scientists are unravelling the mechanisms that drive auroral radio emissions at Saturn’s poles, which are key to understanding certain characteristics of the giant ringed planet. Laurent Lamy, an astrophysicist at the LESIA space and astrophysics instrumentation research laboratory (Paris Observatory) and lead author of an article on the subject in the journal Science, gives us the details.

  15. Cassini reveals giant dust storms on Titan

    Date de publication:

    5 Octobre 2018

    These giant dust storms seen at the equator on Titan rise as far as 10 kilometres above the surface. Mars and Earth are no longer the only worlds in the solar system where such phenomena are known to occur. We put three questions to Sébastien Rodriguez, a planetologist at the IPGP global physics institute in Paris and lead author of this discovery published in the journal Nature Geoscience on 24 September.

  16. Saturn’s north polar hexagon

    Date de publication:

    19 Septembre 2018

    Analysis of data from the Cassini probe has revealed that a vortex towering more than 300 kilometres above Saturn’s north pole mirrors the famous hexagon cloud pattern observed lower in the planet’s atmosphere since 1980. Sandrine Guerlet from the LMD dynamic meteorology laboratory in Paris, who has co-authored a paper on this discovery, explains.

  20. Intense sequence for CNES, DLR and JAXA- Hayabusa2 and MASCOT arrive at asteroid Ryugu

    Date de publication:

    27 Juin 2018

    The Japanese Hayabusa2 space probe has reached the end of its 3.2-billion-kilometre journey with its passenger, the French-German MASCOT (Mobile Asteroid Surface Scout) lander. Launched in 2014, Hayabusa2 has completed three orbits of the Sun in four years, after which it began a few weeks ago its very slow approach to its final destination. Since today, Hayabusa2 is now escorting Ryugu at a close distance of some 20 kilometres, collecting images and data from this celestial object that spins on itself in a little more than seven and a half hours. MASCOT is scheduled to land on the asteroid in early October.
