Julien F0CUQ, nous informe que vendredi prochain, le  30 janvier à 14H, les élèves de 6ème du collège Jean XXIII à Pamiers (Ariège) seront en liaison directe avec le commandant Mike Fincke,à bord de la station spatiale internationale (ISS).  Au cours du contact qui durera 10 minutes, l’astronaute répondra aux questions préparées par les élèves. Ce contact est la continuité du projet sur l’espace mené l’année dernière par les élèves des classes de CE2, CM1 et CM2 de l’école Jean XXIII. C’est la première fois qu’un tel évènement se déroule en Ariège. Bonne écoute sur 145.800Mhz.

ARISS CONTACT PLANNED WITH COLLEGE JEAN XXIII, PAMIERS, FRANCE

An International Space Station school contact has been planned with participants at Ecole & College Jean XXIII, Pamiers, France on 30 January 2009. The event is scheduled to begin at approximately 13.13 UTC, which is 14.13 CEWT.

The contact will be a direct between stations NA1SS and F0CUQ. The contact should be audible over most of Europe. Interested parties are invited to listen in on the 145.800 MHz downlink. The participants are expected to conduct the conversation in English.

Participating students are 10 - 12 years old. The High school is called Jean XXIII, which is the name of the famous Pope from 1960. The school is located in Pamiers, in the Ariege department, at the foot of the Pyrenees, in the south-west of France. Pamiers counts about 15,000 inhabitants: it's the home town of musician Gabriel FAURE. The school has  220 children in the primary school and 300 in the secondary school. The school has two extra-curricular options : one's a football team and the other provides training as a fireman.

Some students worked on space and planets last year and a radio contact had been planned with French astronaut Leopold EYHARTS, which unfortunately didn't happen. Students are very happy and pleased to have the opportunity to talk with an astronaut about his job and they thank him very much for answering their questions.

The control operator will ask as many of the following questions as time allows:
1. Is it the first time you have been in space?
2. How was your trip from the Earth to the space station? How long did it take?
3. How many astronauts are there in the shuttle?
4. How long have you been an astronaut?
5. When you were a child, did you want to be an astronaut?
6. How long do you have to stay in space?
7. How do you communicate with your family?
8. What clothes do you wear? Are your spacesuits comfortable?
9. Do you have pets?
10. Do you do any sport?
11. What happens if you are sick? Do you have medicine to treat yourself?
12. Is there a time difference in space?
13. What is the temperature outside? And in the space station?
14. How do you generate and store electricity?
15. How much time does it take you to go around the Earth?
16. What do you do with your rubbish?
17. How does your day at the station go?
18. What is life like in zero gravity?
19. Do you ever get out of the spaceship? How do you manage to do so?
20. Does the Earth look beautiful from space?

ARISS is an international educational outreach program partnering the participating space agencies, NASA, Russian Space Agency, ESA, CNES, JAXA, and CSA, with the AMSAT and IARU organizations from participating countries.

ARISS offers an opportunity for students to experience the excitement of Amateur Radio by talking directly with crewmembers onboard the International Space Station. Teachers, parents and communities see, first hand, how Amateur Radio and crewmembers on ISS can energize youngsters' interest in science, technology, and learning.

Dernière minute => Télébridge Réussi !  Félicitations à Shane VK4KHZ ainsi qu'à l'équipe du CERAM.

Ce matin mon baromètre est descendu en dessous des 975hPa(*), je ne me souviens pas l'avoir déjà vu aussi bas depuis décembre 1999. C'est un  Torricelli fabriqué en France par les ateliers Altitude, spécialistes en instruments de barométrie. Entre parenthèses, j'aimerai bien connaitre l'historique des mesures depuis 1870. Bref, il y a eu de fortes rafales à Clermont L'Hérault dans l'après-midi mais c'est sur l'ouest du département à la limite de l'Aude qu'il y a eu des dégats. Espérons qu'il n'y aura pas trop de victimes en Aquitaine et Midi-Pyrénées.

(*) Voir le commentaire de Laurent F1JKJ à ce sujet.

Ce que nous savons du  réchauffement global, c'est d'abord la belle unanimité qui règne dans la communauté scientifique depuis la déclaration commune des académies des sciences à l'été 2005. Ceci dans l'histoire des sciences est assez rare, il faut le souligner. Leurs conclusions sont sans équivoque, ils appellent les dirigeants du monde à, je cite :

• établir des standards et développer des instruments économiques pour l’efficacité ainsi qu’à s’engager à promouvoir l’efficacité énergétique pour les habitations, les appareils, les moteurs, les systèmes de transport et dans le secteur de l’énergie lui-même ;

• promouvoir la compréhension des problèmes du climat et de l’énergie et encourager des changements nécessaires de comportement dans nos sociétés;

• définir et mettre en oeuvre des mesures visant à réduire la déforestation globale ;

• renforcer les échanges économiques et technologiques avec les pays en développement, afin de mettre en place directement des technologies modernes plus propres et plus efficaces.

• investir fortement dans la science et la technologie dans le domaine de l’efficacité de l’énergie, les ressources énergétiques dépourvues de carbone et les technologies de capture et élimination du carbone.

Pourquoi dans ces conditions pousser nos chercheurs à aller voire ailleurs ? Pourquoi faut-il fermer plus de la moitié des centres météo en France ? Pourquoi certains élèves n'ont pas eu de livre de sciences entre les mains pendant leurs années de collège ? Sommes-nous au XXIème siècle ;-D ? Mon optimiste me pousse à croire qu'en fait nous vivons toujours une époque moderne.

Mais revenons au réchauffement climatique. La puissance de calcul actuelle et nos meilleurs modèles mathématiques donnent des scénarios à 2 degrés de plus en moyenne en hiver pour la période considérée. C'est à dire que si l'on prend pour référence la période 1960-1989, le réchauffement pourrait atteindre jusqu'à +6°C sur le sud-ouest pendant les étés de la période 2070-2099.

Un télébridge est prévu entre les stations NA1SS et ON4ISS pour 
l'hopital des enfants malades à Ottawa(Canada). Donc si tout se 
déroule bien, vous pourrez entendre la voie descendante comme 
à l'habitude sur 145.800Mhz +- doppler. L'échange se déroulera en 
anglais, vous avez la liste des questions un peu plus bas. 

Pour savoir qui répondra (je parie sur Sandy ;-) soyez à l'écoute à 
partir de 19h00 locale.

En ce début d'année ce ne sont pas les bonnes résolutions qui manquent mais surtout une réelle volonté pour les appliquer. Je veux croire que dans quelques jours la raison l'emportera car au fond l'immense majorité des bipèdes qui peuplent notre petite planète bleue aspire à vivre paisiblement. Bref, pour en revenir aux bonnes résolutions, j'ai décidé de me mettre sérieusement aux hyperfréquences. J'ai la chance pour cela d'être guidé par Christian F6CQK, il partage la couverture du Radio-REF de décembre dernier avec sa parabole pour l'EME (communications Terre-Lune-Terre) et le touriste de l'espace Richard Garriott W5KWQ.

Une discussion récente avec mes voisins m'a permis de constater que les hyperfréquences aussi appelées micro-ondes sont non seulement un sujet d'inquiétude mais qu'elles permettent aussi de faire prendre les couleurs de l'arc-en-ciel à un banal CD...
