Back In The Soyuz Again?

The good news is that we probably won’t have to abandon the International Space Station after all. The bad news is that we’re still dependent on the Russians to get our astronauts there.

NASA Confirms Russian Soyuz Failure Findings

An independent NASA panel reviewing data related to the Aug. 24 failure of the Russian Soyuz rocket transporting cargo to the International Space Station has confirmed that the Russian space agency correctly identified the cause of the problem and is taking appropriate steps to resolve it before the rocket’s next launch scheduled for Oct. 30, said William H. Gerstenmaier, associate administrator for NASA’s Human Exploration and Operations Mission Directorate.

The Russian space agency, Roscosmos, determined that the most likely cause of the failure was contamination in the rocket’s fuel lines or stabilizer valve, which caused low fuel supply to the gas generator, Gerstenmaier told lawmakers Oct. 12 during a hearing of the House Science, Space and Technology Committee’s space and aeronautics panel.

Hopefully, the Russians have come to the correct conclusion as to what the glitch was on last August’s failed resupply flight and have taken the proper actions to fix the problem.

/although I’d feel a whole lot better if the next Soyuz flight, the first since the August crash, wasn’t manned, just in case the Russians still have it wrong

Progress Fails To Make Progress

It’s been a really bad week for the Russians with two rocket failures in the last seven days and four failures total in less than a year.

Russian Progress space freighter lost

An unmanned freighter launched to the International Space Station (ISS) has been lost.

The Russian space agency said the Progress M-12M cargo ship was not placed in the correct orbit by its rocket and fell back to Earth.

The vessel was carrying three tonnes of supplies for the ISS astronauts.

. . .

It appears the Soyuz rocket’s third and final propulsion stage shut down early. As a result, the Russian federal space agency (Roskosmos) said, the Progress vessel “was not placed in the correct orbit”.

. . .

Officials reported the ship coming down in Russia’s Altai province, some 1,500km northeast of the launch site. A loud explosion was heard in the region and there were reports of windows being blown out, but it is not thought there were any injuries on the ground as a result of wreckage coming out of the sky.

Will cargo crash leave ISS crew high and dry?

It’s not that I was a big fan of the space shuttle, but if the Russians can’t get these recurrent rocket failure problems under control, there’s a possibility that the International Space Station might eventually have to be abandoned, because there’s currently no available alternative to supply the ISS. The ISS managers are putting on a brave face that they can manage the cargo loss, but losing three tons of scheduled resupply has just got to hurt.
