Create AccountCANADIANS ARE masters of the universe. Just look at the numbers. Sure, the U.S. leads the world in spending on space research, laying out roughly US$7 per American each year, while Britain, France and Germany budget between US$4 and US$5 for every citizen.
This is ground zero, the holy of holies of the U.S. space program. The flight control room at Johnson Space Center in Houston is instantly familiar from a dozen movies and a thousand newscasts.
No one knows exactly what the surface of Mars is like, but Robert Zubrin has a pretty good idea. At least some of it, he says, is much like a frozen, god-forsaken corner of the Canadian Arctic called Haughton Crater. The terrain is similar - rough-strewn rock on the floor of a crater 16 km across.
Thomas Bopp is a big, broad-shouldered man with a deep voice, a quiet demeanor and a look on his face that suggests he would like to get this experience over quickly. The 47-year-old amateur astronomer from Phoenix, Ariz.
Driver required to operate robotic rover from 190 million kilometres away. Must be able to negotiate vehicle across rock-strewn martian terrain using commands that take 11 minutes to arrive. Experience with computer games an asset.
Most people would no doubt balk at having to stand on the roof of an elevator as it drops slowly into a dark mine shaft sunk more than a mile into the ground. Not physicist Duncan Hepburn, 53, who shrugs off the task as just another part of his job. Some job.
The Royal Astronomical Society of Canada began in 1868 when 8 amateur astronomers founded an astronomical club in Toronto. An expanded group obtained a charter in 1890, and the name "The Royal Astronomical Society of Canada" was adopted in 1903 with Edward VII's permission.
It was an evening in summer upon the placid and temperate planet Mars. Up and down green wine canals, boats as delicate as bronze flowers drifted ....
Gravity, the fundamental physical property of attraction between all bodies, is here considered mainly as it relates to the study of the Earth.
Physical meteorology links meteorology and physics in studies of 3 core topics: electromagnetic radiation, meteorological thermodynamics and cloud physics. Related topics include stratospheric physics, atmospheric electricity, optics and ACOUSTICS.
Astrophysicists use many branches of physics: nuclear physics to study power-generation in stars; atomic physics to understand the spectra of stars and gaseous nebulae; and gas laws and magnetic theory to probe starspots and flares on star surfaces.
As a thunderstorm grows, or a mature storm approaches, this electric field is reversed. In general, the lower part of a cloud is negatively charged; the upper portions, positively charged. A further positive charge is induced on the Earth's surface below a thunderstorm.
In 1963 the first detection of a molecule (the hydroxyl radical OH) at centimetre-wavelength radio frequencies was made by Weinreb, Barrett, Meeks and Henry of the Massachusetts Institute of Technology.
Noise denotes unwanted or unmusical sounds, especially those that are random or irregular. The attitude that noise is not conducive to the well-being of sentient creatures is as old as history.
The dark grey lunar surface reflects only 7% of the sunlight it receives (comparable to the reflectivity of black soil). The moon is dominated by thousands of craters, ranging from microscopic pits to gigantic Clavius, diameter 230 km.
Nuclear fusion is the combination of the nuclei of two light atoms to form a heavier one. The resulting atom has a smaller mass than the original ones; therefore, nuclear fusion is a method of transforming mass into energy.
Viscosity is the ability of a flowing liquid or gas to develop internal shear stresses that resist flow. In air, viscous forces are generally small in comparison with inertia forces, a condition which leads to flow instability and turbulence.
The north and south magnetic poles are the locations on Earth's surface where the planet's magnetic field points straight downwards (at the north magnetic pole) and upwards (at the south magnetic pole). Conventional compasses which move on a horizontal plane are useless near the magnetic poles.
