Progress Rocket Explodes – Could Cause Problems for ISS

A Russian Proton-M rocket exploded on launch from the Baikonur Cosmodrome in the central Asian nation of Kazakhstan on Monday, resulting in Russia grounding the rocket during the investigation of what happened.

Worse, the toxic fuel that the rocket carried is expected to contaminate the Cosmodrome for two to three months.  That would delay the next ISS resupply rocket, which is scheduled for launch July 27.  The next manned launch is scheduled for September 25, when three new replacement crew members are supposed to head up to the ISS via Soyuz 36.

The incident marked the fifth major Proton launch failure since December 2010.The Proton has been grounded while a Russian governmental commission investigates the causes of the crash and attempts to determine which officials bear responsibility for it, the Russian news agency Ria Novosti reported today (July 2).

The Proton-M crashed about 1.6 miles (2.5 kilometers) from its launch site, Baikonur Cosmodrome in the central Asian nation of Kazakhstan, gouging out a crater reported to be 660 feet (200 meters) wide.

The rocket was carrying 600 tons of toxic heptyl, amyl and kerosene fuel. Rain has helped keep the burning fuel’s poisonous smoke in check, but officials say this smoke could continue to drift, Ria Novosti reported.

The town closest to the crash site is Baikonur, which lies about 38 miles (60 km) away. No injuries have been reported there or anywhere else as a result of the mishap.

However, contamination will likely suspend activities at Baikonur Cosmodrome for two or three months, Ria Novosti reported, citing an unnamed source within the Russian space industry. The launch of a robotic Progress cargo ship to the International Space Station from Baikonur, currently scheduled for July 27, will probably be delayed as a result, according to this source.

The next manned launch from Baikonur is Soyuz 36, which is slated to blast off on Sept. 25 to take three new crewmembers to the International Space Station.

The next Proton-M launch on the docket is currently set to take place July 20 and deliver the Astra 2E communications satellite to orbit. That mission will likely be significantly delayed while the Proton investigation is underway.

The three satellites that crashed Monday were supposed to join theGlonass navigation system, Russia’s homegrown alternative to the United States’ Global Positioning System.

Monday’s mishap continues a string of recent problems for Glonass. Three other satellites bound for the constellation were lost after another Proton crash in December 2010, for example, and the Glonass network’s chief designer was let go last year amid accusations of corruption.

The Proton-M that went down yesterday was insured for 6 billion rubles ($182 million) with the Russian Insurance Center, Ria Novosti reported.

Editor’s note: A previous version of this story referred to the Glonass system as being in development. In actuality, Glonass has been operational since the 1990s.
