Resumen: INTHE last decades, studies on the dynamics of a spacecraft that is moving in the gravitational field of a celestial body and subjected to some low-thrust propulsion system have attracted the attention of many researchers in astrodynamics.
Here, we consider a particular case, the so-called Tsien problem [1], in which the spacecraft moves in a circular Keplerian orbit (often referred to as the parking orbit), and after a given time t0 0, it is subjected to a constant outward radial acceleration.
By using the integrals of energy and angular momentum, this problem can be reduced to a two-dimensional scenario. Denoting by r and ? the polar coordinates that give the position of the spacecraft in the plane of the orbit [1], the differential equations that define their motion are ...
