The paper has developed and proposed a syn- thesis analysis method based on the robust satellite data analysis technique （RST） to detect seismic anomalies within the bi-angular advanced along-track scanning ra- diometer （AATSR） gridded brightness temperature （BT） data based on spatial/temporal co.tinuity analysis. The proposed methods have been applied to analyze the Yushu （Qinghai, China） earthquake occurred on 14th April 2010, and a full AATSR data-set of 8 years data from March 2003 to May 2010 with longitude from 91~E to 101°E and latitude from 28°N to 38°N has been analyzed. co.bining with the tectonic explanation of spatial and temporal co.tinuity of the abnormal phenomena, the analyzed results indicate that the infrared radiation anomalies detected by the AATSR BT data with nadir view appear and enhance gradually along with the development and occurring of the earthquake, especially along the Ganzi-Yushu fault, Nu River fault and Jiali-Chayu fault; more infrared anomalies along the earthquake fault zone （Lancangjiang fault and Ning Karma Monastery-Deqin fault） are detected using the proposed synthesis analysis method, which can also characterize the activity of seismic faults more precisely.

This paper discusses the evolutions of invariant manifolds of Halo orbits by low-thrust and lunar gravity. The possibility of applying all these manifolds in designing low-thrust transfer, and the presence of single-impulse trajectories under lunar gravity are also explained. The relationship between invafiant manifolds and the altitude of the perigee is investigated using a Poincare map. Six types of single-impulse transfer trajectories are then attained from the geometry of the invariant manifolds. The evolutions of co.trolled manifolds are surveyed by the gradient law of Jaco.i energy, and the following co.clusions are drawn. First, the low thrust （acceleration or deceleration） near the libration point is very inefficient that the spacecraft free-flies along the invariant manifolds. The purpose is to increase its velocity and avoid stagnation near the libration point. Seco.d, all co.- trolled manifolds are captured because they lie inside the boundary of Eatlh＇s gravity trap in the co.figuration space. The evo- lutions of invariant manifolds under lunar gravity are indicated from the relationship between the lunar phasic angle and the altitude of the perigee. Third and last, most of the manifolds have preserved their topologies in the circular restricted three-body problem. However, the altitudes of the perigee of few manifolds are quite non-co.tinuous, which can be used to generate single-impulse flyby trajectories.
