  1. Jason-1 clocks up 10 years of climate observations

    Date de publication:

    6 Décembre 2011

    The Jason-1 ocean-observing satellite has been in orbit for 10 years. In that time, it has helped to build up a 20-year time series of continuous sea-surface measurements to enhance our understanding of climate change.

  2. Jason-2 takes to the air

    Date de publication:

    6 Mai 2008

    Since 1992, altimetry satellites have significantly enhanced our knowledge of the world’s oceans. The Jason-2 satellite is all set to take over the ocean-observing mission of its predecessors Jason-1 and Topex/Poseidon. It recently arrived at Vandenberg Air Force Base, California, in preparation for launch on 15 June.

  3. Fukushima- Forecasting radiation dispersal at sea

    Date de publication:

    28 Avril 2011

    In the wake of the nuclear accident at Fukushima in Japan, the SIROCCO research group in Toulouse, overseen by CNES, has been simulating the dispersal of contamination at sea using imagery from the Jason and Envisat satellites.

  4. COP21 space agenda Jason-3 satellite successfully launched

    Date de publication:

    17 Janvier 2016

    The Jason-3 oceanography satellite was launched Sunday 17 January at 19:42 CET from Vandenberg Air Force Base (VAFB), California, by a Falcon 9 launcher supplied by NASA. The satellite then came under control of teams at the Toulouse Space Centre to switch on the bus and payload. Jason-3 will now begin its mission to extend the long record of high-precision ocean current and sea-surface height data built up by its predecessors TOPEX/Poseidon, Jason-1 and Jason-2.

  6. Sea elephant oceanographers: a 10-year success story

    Date de publication:

    6 Mai 2013

    For the last 10 years, more than 200 elephant seals have been patrolling the southern seas wearing some strange headgear: an Argos transmitter instrumented with temperature, salinity and pressure sensors. The data these sensors acquire are fed in near-real time into the Mercator operational oceanography model and also tell us more about the animals' ecology.

  7. Jason-2 all set for the off

    Date de publication:

    17 Juin 2008

    The Jason-2 oceanography satellite is now in the home straight and set for launch Friday 20 June. Before reaching final orbit, the satellite will go through a sequence of steps just after launch and during the beginning-of-life phase of its mission. Jason-2 teams are watching launch preparations advance in California with much relief after a series of setbacks over the last 2 weeks. First, successive delays in the launch of the GLAST satellite pushed back the departure of Jason-2, since the same ground teams were preparing both satellites; and then poor weather prevented the satellite from being mated with the launcher as planned.
