Russian rocket carrying Mexican satellite crashes in Siberia

A Russian rocket carrying a Mexican satellite malfunctioned and crashed in Siberia soon after launch on Saturday, the latest in a series of mishaps for Russia's space industry.

The third stage of the rocket carrying the MexSat-1 communications satellite suffered a problem about 500 seconds after launch from the Baikonur cosmodrome in Kazakhstan, Russian media quoted Russian space officials as saying.

The final stage of the Proton could still have contained a few tonnes of heptyl, a highly toxic rocket propellant, when it came down in the Chita region of Siberia, reports quoted one space official as saying.

Proton-M carrier rocket malfunctioned, the Russian Federal Space Agency said in a statement, adding that it was looking into what had happened.

The cause of the accident, however, was not immediately established

Russian news agencies quoted authorities in eastern Siberia as saying they are searching for the third stage of the rocket, which is believed to have crashed there.
 
RIA news agency quoted one space official as saying that all launches of carrier rockets of this type would now be suspended. Russia's workhorse Proton rocket, known at the time under its UR-500 code, made its first test flights in the mid-1960s.

The Proton rocket was originally designed as an intercontinental ballistic missile to carry a nuclear warhead targeting the Soviet Union's Cold War foe the United States. But it was never deployed as a nuclear weapon.

Russia's space industry, which pioneered space exploration with the launch of the first satellite and put the first man into space, has been haunted by accidents which have tarnished its reputation.

In late April, Russia abandoned a 2.6 billion rouble ($51 million) mission to supply the International Space Station, (ISS), after an unmanned Progress M-27M cargo ship, carrying almost 3 tonnes (2,722 kg) of supplies, was unable to dock with the ISS because of problems.

In July 2013, a Proton carrier rocket carrying three navigation satellites worth around $200 million crashed shortly after lift-off from the Russian-leased Baikonur cosmodrome.

Just a few hours before Proton's crash on Saturday, the Progress M-26M spaceship docked at the ISS failed to ignite its engines and correct the orbit of the space outpost, Russian media reported.
