China Succeeds in Orbital Docking

Chalk up another high profile success for the Chinese Space Program.  Earlier today, the unmanned Shenzhou-8 spacecraft successfully docked with China's first orbiting space lab, Tiangong-1.  This docking was performed automatically, which means there was no human control over either spacecraft during the last 50 kilometers of approach.  An impressive feat, by any standards.

Shenzhou-8 will spend the next 12 days docked to Tiangong-1.  The spacecraft will then undock, and then re-dock to prove all systems are functioning properly.  After spending two more days attached, the two craft will separate for the last time, and Shenzhou-8 will head back to Earth.  China plans on sending two more Shenzhou spacecraft to dock with the orbiting lab, one of which will carry a crew of three taikonauts (Chinese astronauts) for a short stay aboard Tiangong-1.

With this automated docking, China takes another step on its ambitious path of space exploration.  What makes this even more impressive is that only a handful of nations have accomplished this task.  The US, Russia, Japan, and the European Space Agency have all developed this technology on their own, and each has successfully sent craft to the International Space Station.  Now that China has demonstrated its ability to dock spacecraft automatically in orbit, it will be possible for the construction of a full-fledged Chinese space station to begin.  China plans to begin construction on a manned station, comparable to the Soviet space station Mir, by the beginning of the next decade.

I, as always, applaud China's progress in space exploration.  However, China's success in space flight always stirs up worries here at home about America's perceived decline as the preeminent space power.  Just last month, private space entrepreneur and founder of Bigelow Aerospace, Robert Bigelow, claimed that China has the ambition and ability to lay ownership to large swaths of the Moon.  Ambition, perhaps, but the ability to land people on the surface of the Moon is in China's distant future, if at all.  As it is, China simply doesn't give their various space agencies the funding they need to develop a truly heavy lift rocket capable of putting large payloads into Lunar orbit.  Add that to the fact that whatever China does in manned spaceflight, they'll being doing it alone.  Their manned program remains shrouded in military secrecy, sequestered from the openness of the international scientific community.  It is, ultimately, an unsustainable path that is doomed to fail.  Tourists will be spotting craters from lunar orbit in spacecraft built by Boeing and SpaceX long before China lands people on the Moon - so don't lose any sleep.

China On the Rise

China's space program is making waves once again.  It is expected that before the end of this month, China will launch their first space lab, Tiangong 1.  Weighing in at 8 tons, Tiangong 1 is small by space lab standards (The U.S.'s Skylab of the 1970's was over 80 tons, and the ISS weighs in at a whopping 450 tons!), however, it does represent a technical achievement.  While not a "space station", in the strict sense, the single module Tiangong 1 will orbit for several years, and be a platform for both robotic and manned missions to practice docking procedures.  The lab will also host at least two crews for several weeks at a time.  The knowledge gained from the Tiangong 1 missions will serve China well when they develop a full fledged space station sometime in the early 2020s.

Certainly, Tiangong 1 showcases China's ever increasing ability in the realm of manned space flight.  And coming on the heels of the retirement of the US Space Shuttle, it might be easy to think that China will soon overtake America in space.  We must remember though, China has only launched three manned space missions in the past 8 years.  And while Tiangong 1 is a significant achievement, it is a step that the US and Russia took and surpassed nearly half a century ago.  To be clear, Tiangong 1 does not represent a threat to Western supremacy in space.

Indeed, the very idea of a China-US space race is highly unlikely, even in the distant future.  First off, manned space flight is no longer the endeavor of just one or two nations.  It has been completely internationalized.  We have American, Russian, Spanish, Japanese, and every other nationality you can think of, riding Russian rockets to the International Space Station.  As far as most space faring nations are concerned, the way forward is through international cooperation.  If China is vying for a No.1 position, they will be taking on the rest of the world.  That isn't something that China can afford to do, at this point.  And, in fact, China would benefit immensely from distancing their military from their manned space missions, and opening up to a more international approach.

To show that China isn't a one trick pony, they successfully launched a new ocean observing satellite this week.  The Haiyang 2A satellite will replace older ocean observing satellites, and is equipped to monitor currents, surface winds, and other aspects of the maritime environment.  While the satellite's primary function will be to serve as an aid to shipping in China's crowded harbors, its suite of scientific instruments are a positive sign in China's move toward getting real science done in space.

While China has a long way yet to go, both technically and diplomatically, in space, I applaud their efforts.  I anxiously await the launch of Tiangong 1, as well as more Chinese scientific missions.
