ARISS contact planned for school in Toulouse, France

An International Space Station radio contact has been planned for astronaut Thomas Pesquet KG5FYG with Maristes High School, Toulouse, France.

The event is scheduled Monday December 12, 2016 at approximately 13:29 UTC, which is 14:29 CEWT.

This will be a direct radio contact, operated by  F8IDR.

The downlink signals will be audible in parts of Europe on 145.800 MHz.

School information:

The MARISTES TOULOUSE: Collegians living the dream with Thomas PESQUET.

Toulouse is a city which is situated in the south of France right at the heart of the department of Haute Garonne in the Occitania region.  Built around the Garonne River which flows through the heart of the city, Toulouse was the theatre for many notable historical events such as the crusades led by the French Kings against the heretic Cathares during the middle ages. The county of Toulouse was annexed to the French realm at the end of the 13th century.

Today this metropolis and French capital of Aeronautics and Aerospace is home to such prestigious establishments as the Centre National d'Etudes Spatiales (CNES) but also such industrial giants as TAS (Thales Alenia Space) and ADS (Airbus Defence and Space). The famous City de l’Espace, a scientifically oriented theme park, specifically geared towards the discovery, exploration and the development of space travel is one of the many tourist attractions appreciated by visitors to the city.

The College-Lycée Les Maristes Toulouse has been situated in the Montaudran neighbourhood since 2012. The school was built just next to the site of the Montaudran runway. The self-same runway from which the planes of the Aerospatiale, flown by the pioneers of civil aviation such as Jean Mermoz, Henri Guillaumet, Paul Vachet ou Antoine de Saint Exupéry, took off at the beginning of the 20th century.

Over the past three years, the college has been working in partnership with the CNES on the project « Mission eXplore : Je m'entraîne comme un astronaute » involving both the Physical Education and Biology programs. The goal of this project, created by the NASA in 2011, is to give youngsters an insight into life in outer space. The Maristes’ objective with this project, via the bias of the scientific and sporting challenges as well as the project "Liaison ARISS" with Thomas Pesquet, is to promote:the sciences and the professions linked to space studies the necessity of associating regular sports activities with a healthy and balanced diet.

Participants will ask as many of the following questions as time allows:

1. Olivia (9th Grade): Quelle a été votre réaction en entrant dans l'ISS?

2. Pierre-Jean (9th Grade): Pourquoi avez-vous choisi ce métier?

3. Ilona (9th Grade): Quelle a été votre réaction lors de l’annonce de votre mission?

4. Eugénie (9th Grade): Combien de temps a duré l’entrainement?

5. Maelys (9th Grade): Quelle est la chose le plus surprenante dans l’espace?

School information:

Private Salesian High School named of St. Dominic Savio

The Private Salesian High School is the secondary school providing general education that is led by the Salesian Community. The school was established in 1998. They stimulate students to apply knowledge to life, to embrace it wholeheartedly, to face reality with integrity, fortitude and optimism, and to serve society dedicatedly. The school focuses their attention on relationships between students and teachers, and parents and teachers.

The school offers opportunities for students’ involvement in activities which take place after school, at weekends and at holiday time. The school leads international exchange of students with Germany and Spain. Apart from achieving good academic results, the school provides a very wide range of cultural, sporting, physical, biological, geographical, social and extra-curricular activities for students from other schools and the local area. The school has the title of the Local Center for Environmental Activity, and it was awarded as an international Green Flag certificate in Poland - so, its role is to attract the attention of society to ecological problems, and to raise environmental awareness in the public. The "Perspektywy" magazine has placed this high school in the group of the best catholic schools in Lower Silesia. They took the 9th place in the ranking of high schools in Wroclaw in 2016, conducted by the Polish newspaper named "Wyborcza". The school has experience in conducting and coordinating environmental projects, and it has carried out so far four Comenius and Erasmus+ projects, and it was also a partner in a Youth Exchange project about global warming.

During the preparation to the ARISS school contact, students attended an amateur radio course prepared by SP6PWR – a local Polish Amateur Radio Union club (DOT-01 PZK), in cooperation with members from other amateur radio local clubs: SP6ZWR, SP6PSR and SP6PWS. Wlodek SQ6NLN, Piotr SQ6VY and Waldemar 3Z6AEF prepared lectures and workshops on amateur radio classes at school. Teachers of different subjects gave many lessons based on materials the NASA and ESA, associated with the subject matter of the project. School invited a few astronomers, who gave very interesting lectures. Students created models of spaceships, capsules of mankind and science fiction literature. They took part in the 6th Polish-wide Conference of Contributors and Sympathizers of the ARISS programme in Ostrów Wielkopolski. Students and teachers were invited to the Wroclaw Opera to the "Chopin: The Space Concert". During this event, within the World Space Week 2016, a special guest – an astronaut George D. Zamka gave them an award for promoting astronautics and astronomy amongst young inhabitants of Wroclaw. In cooperation with the Wroclaw University, they organised workshops in the astronomical observatory in Bialków, and various activities were undertaken there: observation of the sky, astronomical lectures and exercised astrophysical experience such as building a rocket and a spectroscope. Eventually, a few new amateur radio licensed operators (so-called HAMs) should become active on amateur radio bands in the near future.

Participants will ask as many of the following questions as time allows:

1. Julia (18): What personality features do you need to have to manage and stay in space for so long?

2. Krzysztof K. (17): What were your first activities or experiments in microgravity that you did for your curiosity or pleasure?

3. Krzysztof M. (16): Is it possible to catch flu or cold and if so, can you take the same medicines that we take here on Earth?

8. Jan (16): Is it hard to fall asleep in space?

9. Joasia (16): What are your duties on the ISS?

10. Konrad (17): How well is cosmic rubbish visible from the ISS and how can you protect the ISS against them?

11. Rafal (18) Is it true that the Great Wall of China is only object built by humans that is visible from the ISS?

12. Marysia (18): How do you feel the changes of time during a day on the ISS?

13. Teresa (18): Is it good idea to have pets like a cat or a dog aboard the ISS?

14. Asia (18): Have you got some unusually felling or health problems after a few days in microgravity environment on the ISS?

15. Grzegorz (18): What's your way to deal with boredom in space?

16. Kacper (18): How were you selected to work as an astronaut and how were you selected for this mission to the ISS?

17. Milosz (17): Will you have a Christmas tree on the ISS this year?

ANNONCE BALLON UK le 30 octobre 2016

                                                             Exemple de vue de l'espace


I've got permission for some launches this weekend, and I'm hoping to fly a lightweight 868 LoRa tracker with Pi camera, possibly first thing tomorrow morning, possibly Sunday evening for the sunset, or possibly both.

Compared to previous 868 LoRa flights the data rate will be doubled, so there should be plenty of large images.  Settings for my LoRa gateway are (for channel 0 - change _0 to _1 for channel 1):

frequency_0=869.850
mode_0=4

No need for AFC with this bandwidth, so leave that turned off.

For other receiving software, use these settings:

Implicit Mode
Error Coding 4:5
Bandwidth 250k
Spreading Factor 6
Low Data Rate Opt Off

Launch site is near Ross On Wye, and general heading is SSE throughout the weekend.

Dave

Launch(es) will be on Sunday.  Probably it'll be one flight, in the evening
to capture the sunset.

Dave

J'ai la permission pour quelques lancements ce week-end, et j'espère faire voler un Tracker LoRa léger 868 avec une caméra Pi, peut-être la première chose demain matin, ou peut-être le dimanche soir pour le coucher du soleil, ou peut-être les deux.
Par rapport aux précédents vols 868 Lora le débit de données sera doublé, donc il devrait y avoir beaucoup de grandes images.
Les réglages pour ma passerelle LoRa sont (pour le canal 0 - changement _0 à _1 pour le canal 1):frequency_0 = 869,850mode_0 = 4.
Pas besoin d'AFC avec cette bande passante, donc laisser cela éteint.
Pour les autres logiciels de réception, utilisez les paramètres suivants:
mode implicite
Erreur de codage 4: 5Bande passante 250k
Spreading Factor 6
Low Data Rate Opt Off
Le site de lancement est proche de Ross On Wye, et le cap général est SSE tout au long du week-end.
