The aster mission: Exploring for the first time a triple system asteroid
(2011-12-01)
2001 SN263 is a triple system asteroid. Although it was discovery in 2001, in 2008 astronomical observation carried out by Arecibo observatory revealed that it is actually a system with three bodies orbiting each other. ...
Irazú: cubesat mission architecture and development
(Scopus, 2016)
The Central American Association of Aeronautics and Space (ACAE) and the Costa Rican Institute of Technology (TEC), in partnership with industry and government, have identified the promotion of aerospace as a very promising ...
Alternative paths for insertion of probes into high inclination lunar orbits
(Elsevier B.V., 2007-01-01)
The dynamics of the restricted three-body Earth-Moon-particle problem predicts the existence of direct periodic orbits around the Lagrangian equilibrium point L1. From these orbits, we derive a set of trajectories that ...

Optimal transfer trajectories to the haumea system
(2014-01-01)
This paper provides a preliminary study of a mission to the dwarf planet Haumea, focusing on the travel between the Earth and this Kuiper Belt Object (KBO). We generate a set of transfer trajectories from the Earth to ...
Robust joint target detection and tracking for space situational awareness
(2018)
An increased concern in space situational awareness has resulted from the rise in space debris and its threat to future space missions. For safety reasons, it is critically important to populate and maintain a catalog of ...
