Scarborough UK (SPX) May 28, 2012After Shenzhou 8 departed in November 2011, controllers raised the orbit of Tiangong 1 to preserve it from potential re-entry brought about by the air drag that causes all low orbits to decay. In order to conserve propellant, they chose an altitude (about 375 kilometres) that would use the same air drag to bring the orbit down to the standard 335 kilometre Shenzhou operating height for the

The ambitious plan to land a rover on the Moon in a joint mission with Russia, followed in the future by a sample-return mission, won't make its original timeline. The problems largely stem from the ongoing problems with India's launch vehicle program, which has suffered from a string of performance failures in recent years.
