Notice TW has seen fit to explain his previous tip on Avanti, acknowledges he could have been a bit conservative, quotes an un-named Avanti supporter's views in his post. Fair play to him.

Hey SS - Ur up at the crack of dawn, again.

Where would we be with your invaluable and timely research????

Probably closer to the poor house perhaps.

[share_shark] 07/11/2010 09:23

So where are we guys and gals ?.

Defcon1 or Defcon4 ?. ;-)

GLA and for the boys out there,delighted that the other surged last week. Hope this does the same for you all and us here too.

No wonder "AvantI" has been coming up everywhere in my research !. ;-).

Even came across the Italian " Avanti cookware". Now those pics of the kitchenware did look very nice indeed..........if you are that way inclined.LOL.

Eutelsat Will Not Attempt To Deorbit Failed W3B Satellite

--------------------------------------------------------------------------------

PARIS - The Eutelsat W3B satellite declared a total loss less than 24 hours after its Oct. 28 launch because of a leak in its propulsion system will spend the next 20 to 30 years in its parking orbit following ground teams' inability to guide it into a controlled atmospheric re-entry, satellite manufacturer Thales Alenia Space said Nov. 5.

The company said that it has rendered the satellite inert to the extent possible - emptying its helium pressurization tank and whatever fuel remains in liquid state and can be discharged, as well as draining its batteries - to minimize the likelihood that W3B explodes on contact with any orbital debris it may encounter in its elliptical orbit.

The satellite, which weighed 5,370 kilograms at launch, developed a large leak in a line delivering oxidizer to the propellant tank at some point between lifting off aboard an Ariane 5 ECA rocket from Europe's Guiana Space Center in French Guiana, and when it was released into orbit.

Japan's BSat-3b telecommunications satellite, which was a co-passenger on the launch, is healthy in orbit and showing no sign that anything was amiss either during the launch or during the satellites' separation, BSat-3b manufacturer Lockheed Martin Space Systems of Newtown, Pa., announced Nov. 4.

The Arianespace launch consortium of Evry, France, said its analysis of telemetry data from the launch likewise has turned up no evidence of out-of-boundary vibrations during the rocket's climb through the atmosphere, or any issues during the satellites' release into their parking orbits.

An Arianespace official said the company, conscious of the questions that its customers may have, has sent written assurances to the owners of satellites on upcoming Ariane 5 launches stating that Arianespace sees no reason to delay the next launch, scheduled for Nov. 25. That launch will carry the Intelsat 17 satellite for Washington- and Luxembourg-based Intelsat, and the Hylas-1 satellite for Avanti Communications of London.

The Thales Alenia Space statement said a board of inquiry has been established to investigate what happened with W3B. The board includes the satellite's owner, Paris-based Eutelsat, prime contractor Thales Alenia Space, and propulsion system provider Astrium Satellites. Arianespace also is taking part in the inquiry as an observer, mainly to provide telemetry from the launch.

The inquiry is expected to last one month, but may be extended. A preliminary report is expected in mid-November.

In the 24 hours following the launch, Thales Alenia Space and Eutelsat concluded that W3B did not have enough usable propellant to be guided into a graveyard orbit, generally defined as 200-300 kilometers higher than the satellite's intended operating position 36,000 kilometers above the equator.

The Ariane 5 ECA rocket had dropped off W3B in the specified transfer orbit, with a perigee of 249.2 kilometers and an apogee of 35,907 kilometers. With an orbit-raising maneuver excluded, the manufacturer began designing a series of steps to guide the satellite into the atmosphere, preferably over the southern Pacific Ocean.

But by Nov. 3 the ground controllers concluded that de-orbiting the satellite would not be possible in light of a propulsion situation even more desperate than previously thought. The fuel had begun to freeze, and while the usual partial deployment of the solar arrays provided battery power, the satellite could not be moved.

After performing the propellant purge and other passivation efforts to reduce debris risk, Thales Alenia Space and Eutelsat informed the North American Aerospace Defense Command that W3B should be considered an inert object.

Thales Alenia Space estimated that the satellite's elliptical orbit, which was not substantially changed in the abortive attempt to achieve ignition, will keep W3B in space for between 20 and 30 years before the natural forces of gravity and the Earth's residual atmosphere pull it down. While there are not many satellites that have been stranded in this position, there are numerous rocket upper stages that are left there after launch-____________________________________________________________________Off special note .

just reading bout this company atm also due to launch ka bank next spring.

is there actually a single ka band satellite operating yet? or are we going to be first

[sg31] 05/11/2010 22:58

Well as far as we are aware it's not been launched yet and it's November now......That pretty much rules out October. :-)

[hitch2] 05/11/2010 22:19

Been a holder of AVN for a while saw a copy of November rhps tonight where it says listed under comments "Saterllite launch expected in October" Would they not mean November.

[chrissey] 05/11/2010 20:31

well, I took another 1000 today, I'm not George Soros but maybe one day huh!

As EK would say, it would be rude not to buy at these prices!

[wendsworth] 05/11/2010 20:19

missagain : Having gone on 20% since your purchase..why are you nervous?

The success of the launch was always going to be the initial key critical factor so once a launch date had been announced I sold part of my holding well north of 600p in order to partly under-write my position.

Suggest you do likewise if you're as nervous as you sound about this high risk/high reward investment .

If everything goes according to plan ...you;ll be fine BUT if not ......expect to see your investment halve in value. That's how it is with this type of investment.

If I'm stating the obvious to you..I apologise in advance.

[tonsil] 05/11/2010 16:57

buy on the rumour sell just before the fulfilment

[bongo bwana] 05/11/2010 16:20

THAT might make you VERY popular or unpopular

[missagain] 05/11/2010 16:19

I've had this share since Feb at 494.5p - so why am I getting nervous seeing it going down so close to launch when we is all expecting so much from it and investors piling in pre-and post launch instead of cashing-in and grabbing profits ?

share_shark - do like your contibutions and info to this BB - ty.

[sco77harris] 05/11/2010 16:03

one of my friends just bought in, got at least 2 more people buying in next week, spreading that satellite love

[share_shark] 05/11/2010 14:37

PS. Its nice to see there are folk watching it all in Odessa eh?.

[colva] 05/11/2010 13:50

share_shark

I hope you don,t mind me asking but does your interest in AVN come from info that you picked up as part of your job, info that perhaps has not been made public.

[chrissey] 05/11/2010 12:08

well, plenty of rockets gonna get launched today, I miss that.

[someuwin] 05/11/2010 10:55

[sco77harris] 05/11/2010 10:25

they should send people here, and leave the work to us, we chat more sense than those muppets.

loving avantis new website btw

[sg31] 05/11/2010 09:53

You mean people actually give them any credibility?
