C’est l’une des phases capitales d’une aventure scientifique extraordinaire. La sonde Rosetta lancée en 2004 a réussi ce mercredi matin à se mettre en orbite de la comète Tchourioumov-Guérassimenko.

This is one of the most extraordinary scientific adventures. The probe Rosetta launched in 2004 has united on Wednesday morning with the orbit of the comet (Tchourioumov-Guérassimenko).

“Après dix ans, cinq mois et quatre jours de voyage, cinq passages à proximité du Soleil et 6,4 milliards de kilomètres parcourus, nous avons le plaisir d’annoncer que notre but est enfin atteint” s’est réjouit Jean-Jacques Dordain, directeur général de l’Agence spatiale européenne.

“After ten years, five months and four days voyage, five close orbits of the Sun and 6.4 billion kms travelled, we are pleased to announce that our goal has been attained” rejoiced Jean-Jacques Dordain, directeur général of the European Space Agency.

11h31 : confirmation de la réussite de la mission : “Nous sommes en orbite” (“We are in orbit”)
11h13 : une vidéo pédagogique pour patienter. Il était une fois Rosetta… (An educational/information is awaited. It was a first time for Rosetta…)
11h06 : les propulseurs de Rosetta doivent avoir été allumés. Encore un quart d’heure de suspense… (Rosetta’s Propulsion rockets have been fired)

10h59 : Les manœuvres de mise en orbite commencent dans une minute.

C’est le dernier message de la sonde à quelques minutes des premières manoeuvres.

A partir de 11h ce mercredi matin, les propulseurs de la sonde doivent s’allumer pendant six minutes et 26 secondes. A l’issue de ce processus, Rosetta va se trouver placer en orbite de la comète dont elle n’a cessé de se rapprocher.

Un évènement attendu depuis dix ans par les scientifiques européens. Des scientifiques qui ont été surpris par l’allure de la comète.

About bill

Worked in the technical / engineering area as a Science Laboratory Technician and as an Aeronautics Engineer. The artistic side involves writing under the nom de plume of Billy Olsenn, his recently written play 'A Case of Wine' was staged by the players group Straight Make-Up at the 2012 Birr one act drama festival. It's next staging was in the one act circuit is in Cavan, at Maudebawn on Sat 10 Nov 2012. Then it was performed in the Bray, Co.Wicklow at the very popular one act festival in January 2013. Next play is FEAR. A dark tale about revenge on the cruel death of two pensioners by young thugs. Neighbours hatch a devious and dangerous plan to exact old-style revenge. Bill is a member of the Drama League of Ireland and his plays have been critically vetted and certified as original pieces of work by the DLI. Another literary project is that of commemoration of an aircraft crash on Djouce mountain in Wicklow in 1946. Bill wrote articles for the 50th, 60th and most recently the 70th anniversary, (12 Aug 2016) all were published in the Wicklow Times and ensured the survivors of the crash, all French Girl Guides, were not forgotten. Articles reproduced on this website. But mostly this site gives a more general European and specific French slant on popular and not so popular articles of French news, translated to English by the author. Each article is translated on a paragraph by paragraph basis so easy to read in either language and even possible to improve either language by comparison of the short English and French paragraphs. Amusez vous bien. The author is currently writing an easy to read technical aviation book centered around the Fokker 50. Another interest is that dealt with in another of Bill's websites www.realnamara.net, a Statue of the mother of God, Mary. It was erected in 1972 in Dublin, at the end of the Bull Wall near Clontarf, and my grandfather William Nelson, was the main instigator of that project. I give talks on the history of the statue and my grandfather's adventurous and dangerous life at sea. Technical assistance with each website is by J O'N.
