新华网北京9月30日电(田兆运、谢波)北京时间9月30日16时09分,在北京航天飞行控制中心精确控制下,天宫一号成功实施第2次轨道控制,近地点高度由200公里抬升至约362公里,顺利进入在轨测试轨道。 这次轨道控制是在天宫一号飞行第13圈实施的。此前,在30日凌晨1时58分,天宫一号飞行至第4圈时,北京飞控中心对其成功实施了第一次轨道控制,使其远地点高度由346公里抬升至355公里。经过两次轨道控制,天宫一号已从入轨时的椭圆轨道进入近圆轨道,为后续进入交会对接轨道奠定了基础。

Which pad at JSLC was TianGong 1 (SLS-1 or SLS-2 or another pad)?
One half of the fairing fell near Yemugai village (N383631E1094443), Shaanxi province.About 100,000 people had been evacuated from this zone prior to launch.(source)

Fairly typical military/intelligence agency paranoia at work: Put it deep inland far from population centres so that it is harder to insert spies into the site for espionage and/or sabotage. It demonstrates the site's origins as a top secret military site.
