Ciao, c'e' qualche sito in cui seguire in diretta gli eventi?
www.spaceflightnow.com
 a volte fa le dirette ma non stavolta.. chissa' 
perche'? A me sembra un lancio veramente interessante!
saluti!



il lancio avviene da un sottomarino della marina russa. quindi non penso 
che ci sara' alcuna diretta

Dal blog sembra che ci siano dei problemi.. Non hanno ricevuto segnali o 
quasi..
Ora me ne devo andare a letto,speriamo bene per domani mattina!



Ancora nessun segnale
http://planetary.org/solarsailblog/index_04.html
e fonti russe (non e' chiaro quanto attendibili) parlano di un serio 
problema al lancio

Ho letto stamani su Televideo Rai che era stato ristabilito un contatto, ma 
nulla dip iù.

Il bollettino ufficiale:
In the past twenty-four hours, the Russian space agency (RKA) has made a 
tentative conclusion that the Volna rocket carrying Cosmos 1 failed 
during the firing of the first stage.This would mean that Cosmos 1 is lost.
While it is likely that this conclusion is correct, there are some 
inconsistent indications from information received from other sources. 
The Cosmos 1 team observed what appear to be signals, that looks like 
they are from the spacecraft when it was over the first three ground 
stations and some Doppler data over one of these stations. This might 
indicate that Cosmos 1 made it into orbit, but probably a lower one than 
intended. The project team now considers this to be a very small 
probability. But because there is a slim chance that it might be so, 
efforts to contact and track the spacecraft continue. We are working 
with US Strategic Command to provide additional information in a day or so.
If the spacecraft made it to orbit, its autonomous program might be 
working, and after 4 days the sails could automatically deploy. While 
the chances of this are very, very small, we still encourage optical 
observers to see if the sail can be seen after that time.
strano, io oggi mi sarei aspettato una serie di sparate contro "le 
trombette" e invece niente! :)

 maporcapuzzola....
Ma lanciare la vela solare da un sottomarino č stata una buona idea?
O le percentuali di rischio di fallimento sono le stesse di un lancio da
terra?
Comunque che tristezza questi Von Braun del ventunesimo secolo...

Si sa niente?
Eravamo rimasti col piccolo dubbio che potesse essere in orbita in posizione 
sbagliata, l'hanno mica ritrovato?


 sbagliata, l'hanno mica ritrovato?
No, è finita con l'annuncio dell'agenzia spaziale russa che il razzo Volna
non ce l'ha fatta.

Ci sarebbe questo, ma solo per chi vuole davvero sperare:
10:30 am PDT, June 22 (17:30 UTC)
The Planetary Society as issued the following statement on the fate of
Cosmos 1, the first Solar Sail Spacecraft:
In the past twenty-four hours, the Russian space agency (RKA) has made a
tentative conclusion that the Volna rocket carrying Cosmos 1 failed during
the firing of the first stage. This would mean that Cosmos 1 is lost.
While it is likely that this conclusion is correct, there are some
inconsistent indications from information received from other sources. The
Cosmos 1 team observed what appear to be signals, that looks like they are
from the spacecraft when it was over the first three ground stations and
some Doppler data over one of these stations. This might indicate that
Cosmos 1 made it into orbit, but probably a lower one than intended. The
project team now considers this to be a very small probability. But because
there is a slim chance that it might be so, efforts to contact and track the
spacecraft continue. We are working with US Strategic Command to provide
additional information in a day or so.
If the spacecraft made it to orbit, its autonomous program might be working,
and after 4 days the sails could automatically deploy. While the chances of
this are very, very small, we still encourage optical observers to see if
the sail can be seen after that time.
We await further developments and information coming out of Russia,
STRATCOM, and the tracking stations.
