... Future seminars . P a s t seminars . Seminar council . Ultra-High Energy Cosmic Rays: status of the problem " . ... There are several puzzles Ultra-High Energy Cosmic Ray (UHECR) experimental data. ... Situation with Grezen-Zatsepin-Kuzmin cutoff (break in UHECR proton spectrum due to interaction with CMBR) is experimentally unclear. In this talk I'll review existing UHECR experiments and present their results, future experiments and their possibilities. ...
... The Earth's magnetosphere is not unique. Space probes which have visited the giant planets--Jupiter, Saturn, Uranus and Neptune--found that all were magnetized, even more intensely than the Earth, and all were surrounded by radiation belts. ... The Sun, stars and the distant visible universe are mostly plasma, and it turns out that like the magnetosphere, they too can contain high-energy particles, some of them energized above and beyond the levels found in the Earth's magnetosphere. ...
NASA Mars Orbiter . ... The Mars Global Surveyor mission is designed as a rapid, low-cost recovery of the Mars Observer mission objectives. The science objectives involve high resolution imaging of the surface, studies of the topography and gravity, the role of water and dust on the surface and in the atmosphere of Mars, the weather and climate of Mars, the composition of the surface and atmosphere, and the existence and evolution of the Martian magnetic field. ...
