MOSCOW, March 8 (UPI) — A new crew for the International Space Station will install equipment to monitor Earth’s atmosphere and forecast natural disasters, a Russian cosmonaut says.
The crew will lift off from the Baikonur space center March 28 abroad a Soyuz-TMA-08M carrier rocket, ISS-36 Crew Commander Pavel Vinogradov told RIA Novosti Thursday.
The new equipment — a complex system of sensors and antennas designed to study the plasma/wave processes in the upper layers of Earth’s atmosphere — will be installed on the outer surface of the station’s Russian segment during one of the four spacewalks, he said.
It is intended to “eventually benefit mankind by forecasting earthquakes and other natural disasters,” Vinogradov said.
A new Russian laboratory module will be docked with the ISS to expand the Russian segment this year, he said, and a research/power module will be added next year.
Aerospace is the broader term that includes activities related to manmade flight in the earth’s atmosphere and outer space. The U.S. Department of Defense (DoD) defines aerospace as of or pertaining to Earth’s envelope of atmosphere and the space above it; two separate entities considered as a single realm for activity in launching, guidance, and control of vehicles that will travel in both entities. Aviation is a subset of aerospace, referring to activities related to manmade flight within earth’s atmosphere.
Aruvian’s R’search analyzes the United States Aerospace & Defense Industry in Michael Porter’s Five Forces Analysis. It uses concepts developed in Industrial Organization (IO) economics to derive five forces that determine the competitive intensity and therefore attractiveness of a market. Porter referred to these forces as the microenvironment, to contrast it with the more general term macro-environment. They consist of those forces close to a company that affect its ability to serve its customers and make a profit. A change in any of the forces normally requires a company to re-assess the marketplace.
Jerry Lang explains how the MPG-Cap Works. Buy here lith.myffi.biz or join us, we can do business together! The MPG-CAP trade; is a revolutionary combustion chamber treatment that increases fuel economy and reduces harmful exhaust emissions. MPG-CAPS trade; consist of 100% active ingredients , with no dilutents or ?llers, and are safe to use and handle. They are manufactured as a convenient, easy to use, solid caplet which you simply drop in your fuel tank prior to ?ll-up. Emissions testing with the use of MPG-CAPS trade; has shown reductions of smog producing emissions such as hydrocarbons, carbon monoxide and nitrogen oxides. These emissions are harmful to the earth's atmosphere and contribute to global warming. The benefits of using MPG-CAPS Improved fuel economy and increased power Protection of valves and reduction of carbon buildup Reduction of greenhouse gases Elimination of ping and dieseling Increased octane in lower grade fuels Prolonged life of spark plugs, glow plugs and valves For use in all gasoline and diesel powered engines Cars Trucks Boats Motor homes Generators Motorcycles Heavy equipment, and more! MPG-BOOST trade; Combustion chamber catalyst Using the same revolutionary technology as the MPG-CAPS trade;, MPG-BOOST trade; is an engine combustion chamber treatment in liquid form that increases fuel economy and reduces the amount of harmful emissions released into the environment. MPG-BOOST trade; utilizes a unique combustion catalyst developed from aerospace technology that offers a maximum performance. This catalyst, which is found …From:pozitivZnegativPViews:1 0ratingsTime:01:25More inAutos Vehicles
28-06-2012 08:19 An international team of astronomers using data from NASA’s Hubble Space Telescope has detected significant changes in the atmosphere of a planet located beyond our solar system. The scientists conclude the atmospheric variations occurred in response to a powerful eruption on the planet’s host star, an event observed by NASA’s Swift satellite. The exoplanet is HD 189733b, a gas giant similar to Jupiter, but about 14 percent larger and more massive. The planet circles its star at a distance of only 3 million miles, or about 30 times closer than Earth’s distance from the sun, and completes an orbit every 2.2 days. Its star, named HD 189733A, is about 80 percent the size and mass of our sun. Astronomers classify the planet as a “hot Jupiter.” Previous Hubble observations show that the planet’s deep atmosphere reaches a temperature of about 1900 degrees Fahrenheit (1030 C). HD 189733b periodically passes across, or transits, its parent star, and these events give astronomers an opportunity to probe its atmosphere and environment. In a previous study, a group led by Lecavelier des Etangs used Hubble to show that hydrogen gas was escaping from the planet’s upper atmosphere. The finding made HD 189733b only the second-known “evaporating” exoplanet at the time. The system is just 63 light-years away, so close that its star can be seen with binoculars near the famous Dumbbell, or Apple Core, Nebula. This makes HD 189733b an ideal target for studying the processes that drive …
A meteorite that fell to Earth 41 years ago is helping scientists unlock clues regarding the makeup of Mars' atmosphere and its potential implications to help shape future missions to search for evidence of life on the Red Planet, a new study finds.
