China Sends Up Another ‘Practice’ Satellite

On Sept 28, China, unsurprisingly, launched another satellite in their weird passive/aggressive way.  At least it seems passive/aggressive with China advertising it’s a practice satellite but then keeps its mission secret.  On the other hand, the US does the same thing with its military and intelligence satellites as well.

The newest Chinese satellite is called the Shijian-11.  According to Astrowatch, the Chinese word “Shijian” means practice.  The satellite was launched into an orbit that matches the typical orbit of imagery satellites.  Zarya. info, a website that monitors the activities of certain satellites closely, lists the Shijian-11’s orbit as having an inclination (the angle of the satellite’s orbital path relative to the Earth’s equator) of slightly over 98 degrees.  It also lists the time it takes the Shijian-11 to orbit the Earth as about 98 minutes.  The satellite’s altitude isn’t very high, 687 x 705 km (425 x 438 mi), so it’s definitely a low earth orbit satellite.

It seems to be too soon to tell exactly what the satellite is doing, but it may be to help China’s space corps practice more with taking pictures of places on the Earth.  China does have other practice satellites in orbit, so a new one shouldn’t be too shocking.  But older Shijian satellites have done some interesting things, especially in 2013, when Zarya  was observing the maneuvering capability of particular Shijian satellites and a possible robotic arm on one of them to grab other satellites.

This is just another in a series of steps in which China seems to be moving quickly forward in learning more about space operations.   This post from The Diplomat even somewhat hesitatingly states that China’s government is ordering the People’s Liberation Army to establish an actual space force.  Between the practice satellites and their establishment of a space force, China seems to seriously be working on their space operations skills.  Shijian makes perfect, I suppose.
