In an unprecedented space collision, a commercial Iridium communications satellite and a defunct Russian satellite ran into each other Tuesday above northern Siberia, creating a cloud of wreckage, officials said today. The international space station does not appear to be threatened by the debris, they said, but it’s not yet clear whether it poses a risk to any other military or civilian satellites.

“They collided at an altitude of 790 kilometers (491 miles) over northern Siberia Tuesday about noon Washington time,” said Nicholas Johnson, NASA’s chief scientist for orbital debris at the Johnson Space Center in Houston. “The U.S. space surveillance network detected a large number of debris from both objects.”

Found two interesting posts about how Twitter becomes a real-time news media and how it contributes to spread news all over the World despite telecommunication networks breakdown and/or government censorship.

Smart Mobs author Mark A.M Kramer asks if Information and Communication Technologies (ICT) could make humanity morally accountable ? Today, even with a very limited presence of the International community (politics, journalists as well as Aid workers) we continue to receive near real-time information from Myanmar through various multi-plateforms communication media such Twitter, SMS, RSS etc.

Ten days later, in China, an powerful earthquake shook the Sichuan province, information that Technology blogger Robert Scoble claimed that Twitter had the breaking news even before the United States Geological Survey, which provides early warnings of seismic events.

Is Twitter's slogan "What are you doing" should be now replaced by "What's going on" ?

TGV tests Wi-Fi + satellite link in three TGV trains on its Eastern network. If the experiment proves successful the new service should be generalized, from 2009, to all 52 oars network East.

With combines effort of satellite link and wireless network, in locations, such tunnels and train stations, where the satellite link cannot be established, the wi-fi network takes over to maintain the access to the Web without interruption.

French railways company SNCF previously conducted unsuccessful test using GPRS data network before launching a 2 years research and preparation program to implement this dual solution. Among technical difficulties to overcome are these related to 320 km/h TGV trains speed which causes instability and vibrations. 

The project is done in a partnership with Orange(France Telecom mobile operator), Capgemini, Alstom Transport and Eutelsat.

SNCF will put on board of its TGV a dedicated Web portal providing information about destinations, weather forecast, News, traffic information as well as a real time tracking service. From a technical point of view, TGV trains are fitted with a server where all portal content is loaded prior the journey in order to minimize bandwidth consumption due to its high cost. The tested system has been designed to provide simultaneous web connection for 14 per cent (50 users) of the total capacity of each TGV train (350).

The business plan is not defined yet, but the widespread of the system on TGV Eastern Europe network would represent an investment of 120 millions USD over 4 years. First price estimation given by SNCF Passenger service would be a flat 4-5 USD to access the Web portal during the whole journey and a 4-5 USD per hour to access the Internet.

A very interesting project and definitively a real challenge to maintain permanent web connectivity during a train journey at more than 300 km/h where the 16'000 volt power line running over the train may also create some electro-magnetic interferences and without mentioning all micro interruptions of the satellite link each time the train pass under a bridge or when dense foliage is found within the satellite's line of sight.

Any reader who already had the chance to test the reliability of the service ?

People affected by California wildfires get and send firsthand information using micro-blogging service Twitter. Usually during emergencies, all telecommunications networks get overloaded due to huge communication flow increase in all affected areas.

2004 Tsunami taught us that when telephone landlines do not work anymore, mobile network is overloaded, short-messages (SMS) were still going through, but often with up to a hour delivery delay (better than no communication).

One of the most critical problem to solve during emergencies is how to spread information on both directions (from affected people to emergency services and from helpers to victims). In addition, affected people and their relatives are in need to get in touch.

In California, the American Red Cross, among others, have open 2 Twitters threads. One is made to push information out (e.g evacuation routes) and the 2nd one is "Safe and Well" which provides a way for affected people to register as “safe and well.” using a list of standard messages.

Concerned relatives can search the list of those who have registered themselves as “safe and well.” directly on American Red Cross website.

Free and universal Wi-Fi community builder "FON Movimiento" is spreading fast across Europe. In September an agreement was signed with Cegetel, France 2nd largest ISP to introduce the free "Neuf Wifi FON" service. This service offers Neuf Cegetel's subscribers to share some of their Internet bandwidth through their "Wifi Neuf Box" and to become part of the FON community. Cegetel estimates that by end of 2007, 1 million of "Neuf Box 4" will be ready to support this new service. 

Members of the FON community get free and secured Internet access through any "FON Spots" Wifi Access Point around the globe. 

Earlier this month in United Kingdom, BT also joined forces with FON and offer to 3 million BT's broadband customers to share their Internet access and join the FON community.

Now it is the Geneva city council to sign a convention with FON to consolidate the small existing wireless network available in some key locations of the city. The city council envisages to distribute up to 500 FON routers to its citizens who may wish to share their Internet Access via the FON community (complete story, in French, on TSR telecom blog).

Non-member of the FON community will be able to get access to the Internet through FON Wifi networks using a 3 USD/day fee "FON Access Pass".

Let's hope this solution will be more successful than previous attempts as most of them were sunk by politicians and endless administrative discussions.

" Post Tenebras Lux" ? 

Fifty years ago, the soviet union launched into space a 58.5 centimeters and 83 kilos shiny aluminum sphere equipped with 4 long antennas and 2 radio transceivers.

Sputnik-1 (Спутник-1 / Satellite-1), the first artificial satellite, had triggered what would be called later, "the US vs. USSR Space Race". It orbited 1440 times at 250 kms above Earth surface during 3 months transmitting radio signals on 20 & 40 MHz.

This single event launched new political, military, technological, and scientific developments. The Space Era was born.

Myanmar is now nearly cute off from the Internet (at least for public access), as it seems clear that authorities want to crack down the outgoing flow of information regarding ongoing events.

How ever, Myanmar's Telecom officials blame a damaged submarine cable for the Internet breakdown.  

Any idea which culprit they will point out regarding numerous smashed  cellphone and cameras ?
