  "We are still coordinating and gathering information about the incident," 
Slamet Riyadi, head of Corporate Communications and Affairs (HCCS) at Telkom, 
said. 
Jakarta (ANTARA News) - The Telkom-3 satellite owned by Indonesian 
telecommunication services company Telekomunikasi Indonesia (Telkom) has been 
reported lost, hours after it was launched from the Baikonur Cosmodrome in 
Kazakhstan at 2:31 AM Jakarta time on Tuesday.

The company will not be giving detailed information about the incident, Slamet 
Riyadi, head of Corporate Communications and Affairs (HCCS) at Telkom said.

"We are still coordinating and gathering information about the incident," 
Slamet told ANTARA News.

The Telkom-3 satellite was carried by a Russian-made Proton-M rocket, along 
with a Russian Ekspress-MD2 satellite. The Telkom-3 was scheduled to reach the 
Briz-M upper stage on Tuesday at 11.44 am, and the Express MD2 stage at 12.14 
pm Jakarta time.

The Briz-M upper stage involves releasing the rocket's fuel tank along with the 
relocation of command instruments towards the center. This phase is aimed at 
mitigating shock loads when an additional propellant tank is being discarded.

Russian Federal Space Agency Roscosmos refused to confirm the incident in a 
statement, but said that the satellite was still undetected and that it had run 
into some trouble at the Briz-M stage during its orbiting journey.

"The Briz-M booster and the two satellites have not been detected in the 
transition orbit. We have however received a signal from the booster from an 
interim emergency orbit instead," Roscosmos said in a statement on its website.

The Briz-M fired the satellite's engines at the scheduled time, but they 
operated for seven seconds, rather than the 18 minutes and five seconds they 
have been programmed for.

The loss of the Telkom-3 satellite has added to the list of failures 
encountered during a satellite launch's Britz-M phase. A malfunctioning Briz-M 
booster had earlier led to the loss of the Express-AM4 telecommunication 
satellite in August 2011.

The launch of the Indonesian Telkom-3 satellite has been delayed several times. 
It was earlier scheduled for the middle of 2011, but was postponed until the 
end of 2012. Before it finally blasted off on Tuesday, the launch had been 
scheduled for early June.

This is the first time Indonesia has bought a satellite from the Russian 
company Retshesnev. Its previous Telkom-2 satellite used a France Ariane-5 
rocket and was purchased from the ArianeSpace Company in 2005.

It was originally planned to launch the Telkom-3 with a Yamal-300K satellite, 
while the Ekspress-MD2 was to be launched with an Ekspress-AM8.

In December 2008, Telkom chose ISI Retchesnev, a Russia-based firm, to build 
and launch the Telkom-3 satellite, at a cost of US $200 million. Telkom and 
Retchesnev signed the contract in February 2009.(*)
