Muere una persona en montaƱa rusa de Six Flags en Georgia
April 1, 2011 NASA technicians spun the Global Precipitation Monitor (GPM) satellite up to just over 10 RPM in Goddard Space Flight CenterĀs High-Capacity Centrifuge facility March 31. At that speed, the spin exerted a lateral pressure of 2.4 GĀs, or 2.4 times the force of gravity on the satellite. Spin tests such as these are used to determine whether the forces of launch could adversely affect hardware we put into space, and to test spacecraft chassis design. In this case, a combination of flight hardware parts and the so-called mass model were spun. The mass model simulates the final size, shape and weight distribution of the satellite and itĀs component sensors, fuel, maneuvering thrusters, processing and control equipment. GPM will study global rain, snow and ice to better understand our climate, weather, and hydrometeorological processes. For more on the GPM mission, visit http://gpm.gsfc.nasa.gov/. GoddardĀs 120-foot-diameter centrifuge can accelerate a 2.5-ton payload up to 30 Gs, well beyond the force experienced in a launch. The most intense roller-coasters in the world top out at about 5 Gs, and then only for brief moments. The 2.4 Gs experienced by GPM would be sufficient to prevent blood from flowing up into a personĀs brain, inducing blackout if sustained. Karl B.

Un trĆ”gico incidente sacudiĆ³ el parque de diversiones Six Flags Over Georgia, ubicado a unos 24 kilĆ³metros (15 millas) de Atlanta, en el estado de Georgia, Estados Unidos. Autoridades confirmaron que una persona muriĆ³ y otras mĆ”s resultaron heridas tras lo ocurrido en la montaƱa rusa Goliath, aunque la policĆa del condado de Cobb aĆŗn no detalla las causas exactas ni la identidad de la vĆctima.
Goliath, inaugurada en 2006, alcanza una altura de 60 metros (200 pies), una caĆda de 170 pies y velocidades de hasta 112 km/h (70 mph), por lo que se ubica en el nivel cuatro de cinco en la escala de emociĆ³n del parque. Tras el accidente, Six Flags cerrĆ³ temporalmente atracciones similares en todas sus sedes como medida de precauciĆ³n.
