This paper is devoted to the navigation tasks for space robots operating in the neighborhood of unstable libration points of the Earth-Sun system in the near-Earth space. The motion of robot in space is examined under a circular restricted three-body problem. The possibility of a space robot maneuvering in the near-Earth space with return to the neighborhood of a collinear libration point and s...

In this paper, we extend the first-order post-Newtonian scheme in multiple systems presented by Damour-Soffel-Xu to the second-order contribution to light propagation without changing the virtue of the scheme on the linear partial differential equations of the potential and vector potential. The spatial components of the metric are extended to second order level both in a global coordinates (q ...

Combined heliosphere-astronomical data and models enrich our understanding both of effects the solar galactic environment might have on the inner heliosphere, and of interstellar clouds. Present data suggest that N(Fe+)/N(Do) increases toward the upwind direction of the cluster of interstellar clouds (CLIC) flowing past the Sun. Cloud kinematics and abundances suggest an origin related to a sup...

Accumulation and annihilation of weakly interacting massive particles (WIMPs) in the earth and the sun may be observed by the resulting neutrino signal. We demonstrate that, for certain parts of the SUSY parameter space, present and future neutrino telescopes can expect a higher rate of events due to tau-neutrinos than due to muon-neutrinos. We show how neutrino-oscillation, and in the case of ...

Recently, consumers have become more concerned with foods contain natural ingredients in terms of health and economic. Hence, in this study, the effects of concentrate of smoked and sun dried raisin were investigated at 3 levels (1, 3 and 5%) as a natural humectant to improve the quality and shelf life of flat bread. Results showed that addition of smoked and sun dried raisin improved quality a...

From the last few decades, the space science community has shown considerable interest in missions which take place in the vicinity of the Lagrangian points in the restricted three-body problem (RTBP) of the Sun-Earth and the Earth-Moon systems [1]. Designing trajectories for these missions is a challenging task due to inadequacy of the conic approximations. The RTBP deals the situation where o...

The L1 and L2 libration points have been proposed as gateways granting inexpensive access to interplanetary space. The lunar libration points, in conjunction with the collinear libration points in the Sun-Earth system, may also become primary hubs for future human activities in the Earth’s neighborhood. The associated manifold tubes have been introduced by a number of researchers as the basis f...
