Joo - is aber kein Stress, weil ich genau dann 20min. lang auf`s Klo muss , wobei ich jedoch im Medienraum bin (schlau, nech ! )

Nee, kommt drauf an, was (welches Fach) wir da haben - vielleicht kann ich`s sogar bewegen, dass sich das die ganze Klasse reinziehen darf.

Viele Grüße,
Marxi

am 26. (also der eigentlich vorgesehene Tag) habe ich meinen mathelehrer mal gefragt ob wir nicht in den Filmraum gehen könnten-> "hätteste das mal eher gesagt" der ist anscheinend nach dem Start in der Schule ganz interessiert in sachen Rakete!

also ich teste mal am montag ob sich da was machen lässt den heute ist ja wieder nichts gewesen!

Troubled Rosetta launch scheduled for early next Tuesday or Wednesday

KOUROU, French Guiana (AFP) Feb 27, 2004
The next attempt to launch Europe's comet-chasing spacecraft Rosetta will take place early next week, the launch operator Arianespace said Friday after liftoff was postponed for the second time in 24 hours.
The Ariane 5 rocket was being brought back into final assembly building at the European Space Agency's launch pad here, where technicians would replace an insulation tile that broke off from its main fuel tank, Arianespace Director General Jean-Yves Le Gall told the press.

They would also carry out an inspection of the other insulation tiles that cover the tank to see if any were loose, he said.

The rocket will be brought back on to the launch pad and a second launch attempt will take place "overnight Monday or overnight Tuesday" depending on how the repair work and inspection proceed, he said.

"As of today, a launch for early Tuesday seems feasible to me," Le Gall said.

The countdown clock was stopped on Friday three hours, 34 minutes and 29 seconds before blast off.

Rosetta's flight timetable over the next 10 years is so precise that the rocket has to be launched at an exact second in the pre-dawn hours on any day during its three-week launch window, which closes on March 17.

The craft will meet up in deep space with Comet Churyumov-Gerasimenko in 2014 and follow it on its path around the Sun.

The orbiter, equipped with remote sensors to map and probe the comet's surface, will also send down a miniature laboratory to conduct a chemical analysis of its ice and soil, believed to hold complex molecules that could help explain how life began on Earth.

Le Gall said the tile was found in a final inspection of the launch pad.

The tile broke away apparently because of the expansion and contraction of the tank after it was filled with extremely cold liquid hydrogen, and then emptied, following a failed launch attempt on Thursday.

Thursday's launch bid was scrapped because of high altitude winds, which could have scattered debris onto inhabited areas if the rocket blew up or had to be destroyed for some reason.

If the launch window closes, "we can launch in one year's time to the same comet if we have a larger launch vehicle," said John Ellwood, in charge of the Rosetta mission at ESA.

The alternative rockets for this would be the Ariane 5 ECA, a rocket with a 10-tonne launch capacity that this year will undergo a test flight following a disastrous maiden flight in December 2002, and the Russian rocket, the Proton.

Rosetta and its lander, Philae, should have headed off into space more than a year ago towards another target, Comet Wirtanen.

But that mission was scrapped, and another comet chosen, to give engineers time to carry out reliability checks on the standard Ariane 5 launcher which is taking Rosetta into orbit.

Jau, morgen früh soll`s losgehen....wenn nix dazwischen kommt....seufz

... oder auch in einem Jahr...

Ich drücke mal wieder die Daumen!

So, nun isse erstmal weg von Starttisch. Booster und EPC (erste Stufe) haben einwandfrei funktioniert. Die zweite Stufe mit Rosetta ist in der Freiflugphase. Jetzt heist es ca. 2 Stunden warten...

Jau, gestartet ist sie. Hab ich live im Radio mitgehöhrt.

war echt spannend

Leider war ich gerade im Auto, hätte es mir gerne im Fernsehn angeschaut.

Ich setz schon mal den Helm auf und nehm die Knipse in Anschlag

meine ariane 5 muss leider noch auf das OK von SF warten!

Die Oberstufe hat pünktlich gezündet und bringt nun Rosetta auf ihre Bahn.
Pegi, Du kannst den Helm absetzen und die Kamera wegpacken.
