Astronauts ignore worldly tensions

DO OR DIE:Political discord on Earth are of little concern to Russian and American astronauts on the ISS, who depend on cooperation to do their jobs and stay alive


While the US and Russia traded sanctions last week in a burgeoning crisis over Crimea, astronauts from the two nations rose above the discord in their sanctuary hundreds of kilometers above Earth.

Experts say mounting political and economic tensions between the old Cold War foes are unlikely to upset cooperation in space at the moment — something which would be damaging to both sides. Not that talking politics is taboo aboard the International Space Station (ISS), where Americans and Russians share close quarters, orbiting at an altitude of 400km.

“We could talk about anything. We’d talk about politics,” said retired US astronaut Leroy Chiao, who commanded the ISS for six months in 2004 and 2005.

“With something like this going on, I am sure the crew is talking about it, you know, in a friendly way,” Chiao added.

US astronaut Mike Hopkins, upon returning from the ISS earlier this month after a half-year stay, said he considered his Russian counterparts “close friends” and described cooperation as “very strong.”

Beyond the personal bonds forged in space, experts say the two lead nations in the 15-country collaboration have to get along because of the way the US$100 billion space station was designed.

The Russian and US sections at the ISS have their own toilets and they have separate air-conditioning systems.

However, many complex operations at the football-field-sized orbiting outpost require Russian and US cooperation in space and from control centers on the ground.

NASA mission control in Houston, Texas, leads the effort, and the US pays for the bulk of the yearly operating costs.

Howard McCurdy, an expert on space policy at American University, said it was not all marital bliss at the ISS.

“It is like a divorced couple trying to live in the same house,” he said. “You can do it, it is just not very easy. They both own the house. They both operate the house.”

The US needs Russia to transport astronauts to the space station, and currently pays an average of US$70.7 million per seat, according to a NASA spokesman.

The retirement of the US space shuttle program in 2011 left Americans without a vehicle for ferrying crew to low-Earth orbit and a commercial replacement is not expected to be up and running before 2017.

Reliance on Russia’s Soyuz spacecraft is a key reason the US cannot break off space ties.

However, the immediate future depends on how Russian President Vladimir Putin responds to US sanctions over Crimea, said John Logsdon, a member of the NASA Advisory Council.

“It is always in Russia’s capability to cut off their service,” Logsdon said. “It would be a catastrophe. There is mutual dependence and that provides a good motivation to isolate this from the broader issues.”

Concerns have been raised about US reliance on Russian engines to power Atlas V rockets, which propel military satellites into space, in case Russia were to cut off supplies.

The Pentagon last week told the US Air Force to conduct a review of its use of the Russian-made RD-180 rocket motor in the Atlas V.

However, the US Air Force already has a two-year stockpile on hand, so no drastic measures are imminent, a US defense official said.

NASA also said it foresees no change to relations with Russia in space.

Representatives from Russia, the US, Canada, Japan and Europe have lived continuously aboard the space station in rotating crews for more than 13 years, and the life of the station was recently extended to 2024.
