Successfully docking the first ever commercial spaceship to the government-funded International Space Station is not only a question of competition. Transferring the part of space obligations to private bodies might help encourage agencies to go further. However, even if Dragon helps unloading Russian space, it is still question of funds allocation.

It seems that the Dragon launch and successful docking to the ISS means much more for space flights than previously thought. On one hand, NASA might eventually have received a replacement for retired shuttles.

On the other hand, Russia seems to be gradually losing its potential customers, since the USA, as well as Europe and Japan now possess cargo ships capable of carrying necessary supplies to the ISS. Moreover, the Dragon is capable of delivering cargo back to Earth - an option that neither Progress nor ATV and HTV can boast.

However, if the ISS is not the ultimate target it would make sense to have it replaced for both Roscosmos and NASA, as this would free both agencies from having to maintain the station until 2020.

At least that was an initial aim of NASA's Commercial Orbital Transportation Services (COTS) Program, which includes launches of Dragon (developed by Space Exploration Technologies Corp., or Space X) and ships built by Orbital Science Corporation.

The same might be true for Russia, as the ISS, as many critics have pointed out, requires effort and is extremely costly, thus hindering other branches of space science. With a fleet of retired shuttles, the only remaining ship to carry astronauts to the ISS is the Soyuz (with three seats), but it takes a crew of six to keep the station fully functional.

Prospectively, the Dragon will carry people to space as well, as soon more research is done. While Space X, the developer of the ship and its launcher Falcon 9, is sure that human spaceflight will happen in the next few years, the time lag might eventually be a great deal longer.

The second demonstration flight of the Dragon was delayed for a year (meanwhile, the Russian corporation Energia is building a new transportation system that should be ready for the first unmanned launch in 2015, with manned expeditions following in 2018). Nonetheless, it is most likely that first commercially-built spacecraft will berth the station before the end of the decade.

Recently, the Russian Federal Space Agency (Roscosmos) has offered its partners to prolong the ISS expeditions to nine months, instead of the current six-month period, which would presumably reduce the number of manned launches. According to Alexey Krasnov, the head of the human programs of the agency, this would futher promote human flights.

Earlier, the head of Roscomos, Vladimir Popovkin, speculated that it might be more effective to switch to visiting expeditions rather than keep the station constantly manned.
