Hadamard-transform spectrometry of the atmospheres of Earth and jupiter.
A Hadamard-transform spectrometer has been used to obtain a spectrum of Jupiter from 880 cm(-1) to 770cm(-1) Three ammonia absorption features stand out at 870 cm(-1), 851 cm(-1), and 833 cm(-1). The general shape of the spectrum implies an atmosphere with a monotonically decreasing temperature profile up to the 125 K level. In addition, transmission profiles of the earth's atmosphere were take...
متن کاملComparison of Spacecraft Charging Environments at the Earth, Jupiter, and Saturn
Studies of the Earth with the ATS-5, ATS-6, and SCATHA spacecraft led to the development of several simple tools for predicting the potentials to be expected on a spacecraft in the space environment. These tools have been used to estimate the expected levels of worst case charging at Jupiter and Saturn for the Galileo and the Cassini spacecraft missions. This paper reviews those results and put...
متن کاملMigration of Jupiter-family comets and resonant asteroids to near-Earth space.
The orbital evolution of about 26,000 Jupiter-crossing objects and 1,500 resonant asteroids under the gravitational influence of planets was investigated. The rate of their collisions with terrestrial planets was estimated by computing the probabilities of collisions based on random-phase approximations and the orbital elements sampled with a 500 yr step. The Bulirsh-Stoer and a symplectic orbi...
متن کاملThe magnetospheres of Jupiter and Saturn and their lessons for the Earth
The study of planetary magnetospheres allows us to understand processes occurring in the Earth’s magnetosphere by showing us how these processes respond under different conditions. We illustrate lessons learned about the control of the size of the magnetosphere by the dynamic pressure of the solar wind; how cold plasma is lost from magnetospheres; how free energy is generated to produce ion cyc...
متن کاملParticle swarm optimisation of interplanetary trajectories from Earth to Jupiter and Saturn
One of the most fascinating aerospace problems today is the optimisation of interplanetary trajectories in the Solar System, using gravitational fly-bys in order to reduce fuel consumption and/or mission duration. This is a complex optimisation problem due to the complexity of the models and the lack of analytical solutions, as well as to the presence of strong discontinuities. An exhaustive se...
