A lot of confusion. ILS says they got sources everything still goes well, Russian media says the third stage failed (again in a year time) and we all are confused who to believe because we got no direct proof yet what is going on, especially with no telemetry.

I believe ILS is seeing loss of telemetry as a loss but the vehicle could still be performing nominally, while other news sites claim that the loss of telemetry likely equates to a LOV. As tracking data comes in it should become obvious.

Per NK forum, it has already fallen in Russia's Chita region.

I'm not convinced yet either. Let's keep a close eye on this!

Source: Mexican satellite MexSat-1 is likely lost
MOSCOW, May 16 - RIA Novosti. The Mexican communications satellite Mexsat-1, which is output into orbit on a Russian rocket "Proton-M" is likely lost as a result of which occurred on Saturday morning emergency situation, he told RIA Novosti source in the space industry .
"Proton-M" with the Mexican MexSat-1 satellite was launched from Baikonur
"Telemetry rocket" Proton "lost about a minute before the offices of the Mexican satellite from the third stage of" Proton ": in 8.56 MSK. Mexican satellite is not separated from the third stage and is likely to be recognized as lost, as not able to carry out its functions due to the fact that the orbit of its removal was to be 36 thousand kilometers, and now he has not received and thousands of kilometers from Earth "- a spokesman said.

Today, May 16, 2015 in the process of launching rocket "Proton-M" satellite "MekSat 1" emergency situation occurred. The reasons are found out.
Also in the morning on May 16, at the appointed time, not including engines TGK "Progress M-26M" to correct the ISS orbit. The reasons are studied by experts Mission Control Center FSUE TsNIIMash.
ROSCOSMOS be informed as more information becomes available.

Now official!

This is terrible for ILS and the Russian space industry as they didn't need another failure!

.....no details offered eh? (in the case of 365 days ago Roscosmos declared an engine failure pretty early) Hmm.....

Anybody have a guess at the time of the lithobraking event? I pulled up some high resolution Himawari-8 shortwave IR data. If anything caused a sudden exothermic reaction, it should pick it up as a blip. I see lots of active forest fires in the region but I'm having a hard time spotting one "blip" pixel without a time.

The wordings of the release have no details about what happened (just "emergency situation") so I am not convinced that they can confirm an LOV.

I would suggest waiting for ILS (or report of debris on ground like last time) before making a verdict.

This launch no longer exists?

The launch still exists. See

Nothing from ILS, but I expect the next thing we'll hear from them is a statement.

(my translation)
Moscow. 16 May. Interfax.ru The launch of a Proton-M booster with a British communications satellite intended for early June has been delayed until the reason for the failure of a Proton-M on 16 May (MexSat).

Proton launches have been halted, beginning with the planned launch of the British satellite will be postponed, reported an agency representative, who noted that an investigation into the cause of today's crash may require from several weeks to several months.

Earlier today, a source in the aerospace industry reported to Interfax that an anomaly arose in the third stage of the Proton-M launched Saturday from the Baikonur Cosmodrome. "In the 498th second of flight the third stage engine had an emergency shut down," he specified.

The third stage of the booster with the Briz-M propulsion module and the MexSat satellite fell in Chita region, said the source.

The MexSat was built to the order of the Mexican ministry of communications and transportation by the American concern Boeing Satellite Systems. It was constructed on the base of the Boeing 702 NP platform and had a mass of about 4.5 tons, with relay antennas for three bands. The satellite was intended to provide communications to Mexico and the central part of South America for a minimum 15 year operational lifespan.

The Proton-M booster and the Briz-M propulsion module were built by the Moscow Khrunichev Center. The launch was carried out by the commercial launch provider International Launch Services, a Russian-American joint venture which has exclusive rights to commercial launches using the Russian Proton heavy lifter.

The Proton MexSat launch was originally scheduled on 29 April but was delayed because Boeing required additional time to test the onboard equipment. An addtional Proton-M launch has been delayed from April until at least August. Metallic dust was discovered in the plumbing of one of the stages of the booster that was intended to loft the Express-AM8 communications satellite. Correcting the technical issues of the booster required its return to Moscow.

Abnormal Situation in Space

This is the second anomaly in 24 hours that RosCosmos has had to deal with. On 16 May a correction burn planned to lift the orbit of the ISS did not take place because the engine of the Progress cargo vessel which was to be used for the burn sent anomalous readings to the on-board computer on the Russian ISS module which caused an abort burn command.
