For the second time in less than three weeks, a major disaster struck the Russian space program when the launch of a Proton-M rocket ended in catastrophic failure about eight minutes after today’s (May 16) liftoff from the Baikonur Cosmodrome in Kazakhstan, resulting in the complete destruction of the Mexican communications satellite payload.
The Proton-M rocket initially lifted off successfully at 11:47 a.m. local time (1:47 a.m. EDT, 547 GMT) from the Baikonur Cosmodrome in Kazakhstan, but soon experienced an “emergency situation at 497 seconds into the flight,” according to a brief official statement released by Roscosmos, the Russian Federal Space Agency today, after the mishap.
The launch catastrophe was caused by a failure in the rockets Breeze-M third stage, says Roscosmos. It took place during a live broadcast from the agency’s website. A video shows the rocket disappearing into cloudy skies shortly after liftoff.
The failure comes just one week after the spinning, out-of-control Russian Progress 59 cargo freighter bound for the ISS met its undesired early demise when it fell uncontrolled from orbit last Friday, May 8, following its botched April 28 launch on a Russian Soyuz-2.1A carrier rocket, also from Baikonur – as reported by Universe Today – here, here, and here.
The Proton-M carrier rocket was lofting the Mexsat 1 communications satellite, also known as Centenario, under a contract with the Mexican government.
“The failure happened on the 497th second of the flight, at an altitude of 161 kilometers [100 miles]. The third stage, the booster vehicle and the spacecraft almost completely burned up in the atmosphere. As of now there are no reports of debris reaching the ground,” the agency said in a statement.
The Breeze-M third stage was to loft Mexsat 1 to its destination in geostationary orbit over 22,000 miles above Earth at 113 degrees west longitude.
The 58.2 m (191 ft) tall Proton rocket is built and operated by Khrunichev State Research and Production Space Center and marketed by International Launch Services (ILS).
After reaching an altitude of about 161 km (100 mi) the rocket and Mexsat 1 payload fell back to Earth and burned up over the Chita region of Russia, which is located south west of the Siberian Baikal region, said the Russian News agency TASS.
“The rocket and its payload, a Mexican communication satellite, burned up in the atmosphere,” according to a report by Sputnik International, a Russian News agency.
At this time, local residents have not reported or claimed anything regarding possible debris and there is no information about casualties or destruction, TASS noted.
Mi8 helicopters from Russia’s Emergencies Ministry have been dispatched to the area to look for any debris.
The 5.4 ton Mexsat 1 communication satellite was built by Boeing Satellite Systems International for the Mexican government’s Ministry of Communications and Transportation, the Secretaria de Comunicaciones y Transportes (SCT).
The Breeze-M failure occurred about 1 minute prior to separation of the third stage from Mexsat 1.
“The emergency situation happened at 08:56 Moscow time, one minute to the scheduled separation of the Breeze-M booster and the Mexican MexSat-1 space apparatus,” TASS reported.
A malfunction with the third stage steering engine may be the cause of the doomed flight.
“A preliminary reason of the accident with Proton is a failure of the steering engines of the third stage,” sources told TASS.
“The analysis of the telemetry allows for supposing that there was a failure in one of the third stage’s steering engines. This is now considered as one of the main reasons.”
Exactly one year ago, another Proton rocket crashed at a similar point when the third stage engines failed during the Proton launch of Russia’s advanced Express-AM4R satellite.
“Khrunichev and International Launch Services (ILS) regret to announce an anomaly during today’s Proton mission,” ILS said in a statement issued after the launch failure.
ILS said an accident investigation board has been appointed to determine the cause of the failure and recommend corrective actions.
“A Russian State Commission has begun the process of determining the reasons for the anomaly. ILS will release details when data becomes available,” said ILS.
They hope to return the workhorse Proton to flight as soon as possible.
“ILS remains committed to providing reliable, timely launch services for all its customers. To this end, ILS will work diligently with its partner Khrunichev to return Proton to flight as soon as possible.”
This was the eleventh failure of the Proton-M rocket or Breeze-M upper stage in 116 launches since the inaugural liftoff in April 2001.
Mexsat 1 had a planned lifetime of 15 years. It was to provide mobile satellite services to support national security, civil and humanitarian efforts and will provide disaster relief, emergency services, telemedicine, rural education, and government agency operations.
Media reports indicate it was insured for about $390 million.
