Adieu Jason-1! Comme journaliste spécialisé, ce fut une de mes grandes missions pour le CNES: la couverture Internet et le surtout le commentaire de lancement avec Marc Pircher depuis Vandenberg. C'était en décembre 2001. Son altimètre ayant mesuré avec précision la hauteur des océans pendant plus de 11 ans, ce satellite d'océanographie a fini de transmettre. Belle mission, un beau travail. Je pense à  beaucoup d'amis qui m'ont aidé à  remplir cette mission fascinante... François Parisot, Gérard Huttin, Philippe Collot, chère Eliane, et le regretté Yves Ménard.

She was a sweet ride! The Jason-1 engineers, software developers, scientists, and ground support teams should feel very proud.

Very sad. Immensely Successful mission. Provided valuable data sets to the research community. Appreciate the effort of Jason-1 team. We all feel sad that we won't be able to get the data from Jason-1. However, as an application scientist, we could learn so much from Jason-1 data in the field of ocean modeling and data assimilation. I sincerely thank the entire Jason-1 team for giving us so much of valuable data sets. I join you in wishing Jason-2 and SARAL a long life.

Thanks to the one year delay for the launch, Jason-1 offered me the opportunity to make one year of outreach and organize visits for children to see the satellite in integration at Cannes. The results was the "The Geonauts inquire into the oceans" cd-rom. This was the first launch for me and I always remember this exciting event. At this time nobody was thinking that Jason-1 will give us such a harvest of very good data during so many years. It has always accepted all the changes we need (tandem orbit, geodetic orbit) and finally conclude its 406-day geodetic cycle before passing away. Even at the very end of its life it lets us the opportunity to passivate it as planned by the operation teams. So many thanks to Jason-1 for its work as well as to the operation teams for making this success story.

It was a challenge in 1995 to propose to our US partners to use the first PROTEUS platform for the Jason-1 mission and thus take the responsibility of the system development. New instrument, new satellite, new ground segment. It has not been easy, there were a lot of heights and lows up until the launch on December 7th, 2001. GPS, Star tracker, BV1, BV2, Solar array drives mechanism, red team.....all elements that made our nights difficult !!!! but at the end and thanks to the dedication of all, engineers within agencies and industry, scientists, experts, we manage to built a system that has satisfied its users well beyond the initial expectation. All good stories have an end, this time has come for Jason-1. Happily, Jason-2 has taken over and a new generation of engineers and scientists, as much motivated and dedicated as their predecessors is preparing Jason-3 for launch in March 2015 and also paving the way towards Jason-CS. Congratulation to all of you for this impressive achievement and I'm very proud having being and still being part of this endeavour.Francois ParisotAltimetry managerEUMETSAT

let me pay tribute to Jason-1: amongst the many achievements, it has also served the interests of the coastal altimetry community and I am sure, as many others are, that we will continue to mine its data for years to come. The whole mission (like its predecessor and successor) has been a superb gift to oceanography and in this moment, without forgetting the many scientists and engineers that have made Jason-1 a reality, my thought goes to the memory of Yves Ménard who was instrumental in providing that gift.

What a faithful and dedicated friend! Good bye Jason. Thankyou for your tireless work, soaring so high above us, watching patiently over our heaving oceans, advising us, gently, to step back from the edge.

Jason-1 has been rather unique that it has been through three mission phases: the main mission on the TOPEX ground track, an interleaved orbit after commissioning of Jason-2, and finally the geodetic mission. ERS-1 is the only one with more mission phases: seven in total on 5 different orbits.I would also like to extend my thanks to the Jason-1 team for working hard for the mission for many years, maintaining as long as it could. By taking the important but the difficult decision to put it into the "graveyard orbit" about 15 months ago, Jason-1 was set up to become a geodetic mission; that it was never envisioned to become. It will be interesting to see a lot of legacy coming out of those last 15 months of data that will make Jason-1 stand out from TOPEX and Jason-2.

Morrow Rosemary


As Glenn has informed you, the joint steering team for Jason-1, led by CNES and NASA, had to make the difficult decision early this week to terminate the Jason-1 mission. The Jason-1 steering team had been concerned for many years that such a situation may one day occur, which is why we had many discussions with the OSTST to maintain the science value of the Jason-1 mission as long as possible, but to move it off the long term Jason orbit altitude. As you will recall, Jason-1 was moved to its "graveyard" orbit 15 months ago, but with a 406 day orbit which was chosen by the OSTST to be useful for geodetic measurements, but also with a sub-cycle adapted for ocean observations. As such, Jason-1 continued its key role for ocean observing until the launch and validation of SARAL data. Jason-1 had just completed its first full geodetic cycle, before the data transmission stopped functioning.We are all very proud of Jason-1, and all that this mission has contributed to for scientific and operational oceanography, coastal, hydrological and geodetic applications. And on a more personal note, we would also like to congratulate, and give our condolences to, the CNES-NASA operational teams, who have worked so hard, and so professionally, over the last decade so that Jason-1 could continue to provide excellent science data right up to the end.Rosemary, Pascal

Jason-1 was not only a tremendous success as a satellite to measure ocean dynamics but it also completed its 406 day geodetic phase just before its redundant telemetry failed. These new Jason-1 data are resulting in a factor of 2 improvement in the accuracy of the marine gravity field which will provide a whole new view of seafloor tectonic fabric. I would like to than the NASA and CNES teams for keeping the satellite healthy for these 406 days as well as the Jason-1 Extension of Life (EoL) team for recommending and designing this geodetic phase.

Walter HF. Smith


Please convey to all my thanks for a superb job done very well with sustained effort over a long time. The long life of the program demonstrates the superb engineering and manufacturing and the sustained committment of the sponsors and the engineering and ground team. The science results of the Geodetic Mission will continue to pour out for a long time to come, and we continue to see more papers written on the Jason-1 record of oceanography and sea level rise.

Saleh Abdalla


Jason-1 provided invaluable data set that contributed, and will keep contributing, in the progress of a wide range of disciplines. Although I agree with the quote given by Linda Stathoplos of NOAA in the announcement to OSTST "Don't be sad because it's over; be happy because it happened!", still I feel sad.Thanks for all those contributed to this very successful mission.

Stavros Melachroinos


Jason assembled a great group of heroes, known as the Argonauts after their ship, the Argo. A great thanks to the memorable Argonaut Dr. Yves Menard et al. for their legacy. It's up to us now, the new generation of Argonauts, to continue the quest for the Golden Fleece . S.M.
