Not exact matches

Prior to launch, Aurora Station travelers would have three months of training, beginning with online courses to understand «basic spaceflight, orbital mechanics, and pressurized environments in space.»

Sometime in the last thousand years or so, orbital mechanics and gravity delivered the wandering rock to Earth.

My research is in celestial mechanics, including the architecture of extra-solar planetary systems, debris disks around stars, the Kuiper belt and asteroid belt, orbital resonances, and meteoritic bombardment on planets in the solar system.

Prior to launch, Aurora Station travelers would have three months of training, beginning with online courses to understand «basic spaceflight, orbital mechanics, and pressurized environments in space.»

CO2 induced warming goes down, BUT the Milankovitch orbital mechanics still dictate that in 10,000 years we will be closer to the sun, & probably warmer.

Appraising the new work in this context, Thomas Crowley, a climate specialist at the University of Edinburgh, said there are ample signs that Earth's climate, including the great cycles of warm periods and big chills driven by orbital mechanics, is within our sway.

Take a look at Hansen 1993, scaling from radiation changes in last glacial epoch (plain orbital mechanics affecting irradiation), 3 ± 1 °C, Chylek 2007, differences between the Holocene and the last glacial maximum, 1.3 °C to 2.3 °C, and Bender et al 2010, looking at the response from Mount Pinatubo and the volcanic aerosols, with current temperature ranges, 1.7 to 4.1 °C.

Climate models do not in general, simply look up Berger's table of values, but independently calculate insolation based on orbital mechanics.

So, even allowing my error in criticizing you on the orbital mechanics, your theory stands refuted by empirical evidence.

In the distant future it is a certainty that the Earth will warm beyond what we have today and that the next ice age is waiting in the wings, but not for another 30,000 years or so, according to our present knowledge of solar variability and orbital mechanics (IPCC 2007In the distant future it is a certainty that the Earth will warm beyond what we have today and that the next ice age is waiting in the wings, but not for another 30,000 years or so, according to our present knowledge of solar variability and orbital mechanics (IPCC 2007in the wings, but not for another 30,000 years or so, according to our present knowledge of solar variability and orbital mechanics (IPCC 2007).

The drag acts to slow a satellite in its orbital path, and then simple orbital mechanics means the satellite descends into the atmosphere where the denser air heats it to the point it burns up.»

This drag is due to the rare molecules of gas that hover around above the fringe of the atmosphere, and it's the same drag that resulted in the premature deorbiting of the famous Skylab satellite in the 1970s, when the mechanics of orbital drag weren't as well understood.
