1. Space Propulsion: a Survey Study About Current and Future Technologies
ABSTRACT: Current Space Launch Vehicles use chemical reactions (solid and liquid propellants) to achieve sufficient thrust to launch artifacts and humans into space. Propulsion technologies can be framed in three different categories: "escape propulsion", "in-space propulsion", and "deep space propulsion". The launch vehicles currently used for "escape propu

2. Estudo dos efeitos perturbativos do terceiro corpo e do achatamento de um planeta na dinâmica de um veículo espacial: caso Netuno-Tritão / Study of the third body perturbation and the planet s oblatenesses in the dynamics of a spacecraft: neptune-triton case
Na atualidade, as pesquisas para o conhecimento do nosso sistema solar continuam em andamento. Desta forma, em 1 de julho de 2004, a espaço nave Cassini-Huygens entrou em órbita ao redor de Saturno. Em janeiro de 2005, a sonda Huygens enviou diversas informações da maior das luas de Saturno, denominada Titã. Em 19 de janeiro de 2006 acontece o lançamen

3. Estudo dos efeitos perturbativos do terceiro corpo e do achatamento de um planeta na dinâmica de um veículo espacial: caso Netuno-Tritão / Study of the third body perturbation and the planet s oblatenesses in the dynamics of a spacecraft: neptune-triton case
At the present time the search for the knowledge of our solar system continues effective. So, in July 1st, 2004, the international Cassini-Huygens Mission spacecraft entered into orbit around the planet Saturn. In January, 2005, it sends data from the Huygens probe, which is on Saturn s largest moon, Titan. On January 19, 2006, occurred the launch of the New

5. The elliptic-bi-parabolic planar transfer for artificial satellites
The "elliptic-bi-parabolic transfer" orbit for an artificial satellite is an extension of the bi-parabolic transfer that uses a Swing-By with a natural satellite of the main body to reduce the amount of fuel required by the maneuver. The objective is to find the minimum cost trajectory, in terms of fuel consumed, to transfer a spacecraft from a parking orbit

6. A study of geoeffective magnetic clouds in the interplanetary medium / Estudo de nuvens magneticas geoefetivas no meio interplanetario
Magnetic clouds are interplanetary structures whose origins are related to Coronal Mass Ejections (CME). Their features are: strong magnetic field intensity (typically > 10nT4), a large rotation in the magnetic field angle as the cloud crosses the spacecraft, low proton temperature and b5 values (~0.1). For a set of previously published magnetic cloud eve

7. Microbiological Burden on the Surfaces of Explorer XXXIII Spacecraft1
The Explorer XXXIII Spacecraft (Anchored Interplanetary Monitoring Platform, or AIMP) was decontaminated to prevent gross contamination of the moon with terrestrial microorganisms. Assay of the total spacecraft surface before and after decontamination showed that the decontamination procedure reduced the viable microbiological burden from 1.40 × 106 to 3.60
