Two Russian cosmonauts and one American astronaut aboard the International Space Station (ISS) are soon scheduled to fly back to Earth, but the Ukraine conflict and the tension between Russia and the U.S. will not have an affect.

The three ISS crewmembers will fly back to Earth aboard a Russian Soyuz spacecraft March 10. NASA told Space.com they are confident the political climate will not affect the mission at all. After NASA's Mike Hopkins, Russia's Oleg Kotov and Sergey Ryazanskiy land in Kazakhstan, three others will take their place and fly back to the ISS.

"We have an excellent relationship with our Russian colleagues in the space program and obviously the crew has an excellent relationship with one another," NASA spokesman Josh Byerly told Space.com. "All plans are on track for both the landing and the launch that we've got coming up in a few weeks."

NASA astronaut Steve Swanson and cosmonauts Alexander Skvortsov and Oleg Artemyev are scheduled to begin their ISS term on March 25.

The U.S. and Russia are arguably the world's leaders in space exploration and if they continue their conflict, their partnership could easily turn sour. According to NBC News, the Russia-Ukraine conflict and the U.S.'s involvement is feared to potentially become one of the worst diplomatic crises of this generation.

Since the U.S. retired its space shuttle fleet, the only way to leave and arrive at the ISS is through Russia. It currently costs the U.S. $70 million to send each astronaut to the ISS and those checks are written out to Russia.

However, if Russia suddenly refused to send American astronauts to space, the U.S. could stop providing electric and communication services to the Russians, rendering their orbital hardware useless.

Private companies in the U.S. have been able to successfully fly restocking missions to the ISS, a good sign in the event Russia stopped allowing American astronauts aboard their spacecraft. SpaceX and Orbital Sciences have run numerous successful cargo missions, but still need to be able to bring and return astronauts.

The U.S. and Russia seem forced to continue their reliance on each other for space exploration for now. Still, in regards to this current crisis and any more to come, NASA will do itself a favor and develop other options.
