Data collected during MESSENGER's third through sixth month in orbit around Mercury were released to the public today by the Planetary Data System (PDS), an organization that archives and distributes all of NASA's planetary mission data. With this release, data are now available to the public for the first full Mercury solar day of MESSENGER orbital operations. Calibrated data from all seven of MESSENGER's science instruments, plus radio science data from the spacecraft telecommunications...
[ Watch the Video ] Venus, often referred to as Earth’s sister planet due to its similar size, gravity, and composition, has been discovered by astronomers to also have a type of space weather event that is commonly found on Earth: a hot flow anomaly or HFA. HFAs are generally associated with the magnetosphere of a planet, such as Earth. But where Venus has no magnetosphere, the phenomenon surprised astronomers. The astronomers, reporting their findings from a recent study in the...
MESSENGER successfully completed an orbit-correction maneuver on March 2 to lower its periapsis altitude - the lowest point of MESSENGER's orbit about Mercury relative to the planet's surface - from 405 to 200 kilometers (251 to 124 miles). This is the first of three planned maneuvers designed to modify the spacecraft's orbit around Mercury as science operations transition from MESSENGER's primary orbital mission to its extended mission. MESSENGER's orbit around Mercury is highly...
Lee Rannals for RedOrbit.com On February 20, 1962, John Glenn became the first American astronaut to orbit the Earth aboard Friendship 7. Now, 50 years later, we look back at that moment with admiration at what roads that mission was able to pave for our nation. Glenn boldly stepped-up and joined the Mercury-Atlas 6 mission, which was the sixth mission in the Mercury-Atlas set of missions. He knew what was at stake, and although the previous mission saw Enos the Chimp land...
Higher blood levels of cadmium in females, and higher blood levels of lead in males, delayed pregnancy in couples trying to become pregnant, according to a study by researchers at the National Institutes of Health and other academic research institutions. Cigarette smoke is the most common source of exposure to cadmium,, a toxic metal found in the earth's crust, which is used in batteries, pigments, metal coatings and plastics. Smokers are estimated to have twice the levels of cadmium as...
Though generally thought to be quite dry, roughly half of the giant asteroid Vesta is expected to be so cold and to receive so little sunlight that water ice could have survived there for billions of years, according to the first published models of Vesta's average global temperatures and illumination by the sun. "Near the north and south poles, the conditions appear to be favorable for water ice to exist beneath the surface," says Timothy Stubbs of NASA's Goddard Space Flight Center in...
MINNEAPOLIS, Jan. 23, 2012 /PRNewswire/ -- FLW, the world's leading tournament-fishing organization, announced today it has signed a multiyear contract extension with Brunswick Corporation. The agreement will ensure Brunswick brands MotorGuide, Brunswick Zone and Mercury Marine, the world leader in recreational marine propulsion and technology, and FLW anglers will enjoy the mutually beneficial relationship for at least the next two years. Mercury will showcase its marine...
MILLERSVILLE, Pa., Jan. 23, 2012 /PRNewswire-USNewswire/ -- It may come as a surprise that each raindrop can carry a variety of chemicals that cumulatively can be detrimental to human health, as well as the health of ecosystems. These chemicals, including heavy metals such as mercury, can be transported long distances from their sources before raining out. Since 2002, Millersville University of Pennsylvania's Department of Earth Sciences has been involved in a program that...
Southern Research Prepared to Help the Coal-Fired Utilities Industry Address New Mercury and Air Toxics Standards Cost-Effectively Southern Research to give technical presentations at EUEC in Phoenix BIRMINGHAM, Ala., Jan. 17, 2012 /PRNewswire-USNewswire/ -- Late in 2011, when the U.S. Environmental Protection Agency (EPA) on Dec. 21 announced new Mercury and Air Toxics Standards (MATS)--limiting mercury, acid gases and other toxic pollution from power plants--engineers and...

A mercury arc valve converts high-voltage or high-current alternating current into direct current. It is an electrical rectifier often used to provide power for industrial motors, electric railways, streetcars, and electric locomotives. Peter Cooper Hewitt, in 1902, invented the mercury arc rectifier. It was further developed by researchers throughout the 1920s and 1930s. Prior to solid-state devices, mercury arc rectifiers were one of the more efficient rectifiers. Silicon diode and...
Mercury (element) Mercury, also called quicksilver, is a chemical element in the periodic table that has the symbol Hg (from the Greek hydrargyrum, for watery (or liquid) silver) and atomic number 80. A heavy, silvery, transition metal, mercury is one of only two elements that are liquid at room temperature (the other is bromine). Mercury is used in thermometers, barometers and other scientific apparatuses. Mercury is mostly obtained by reduction from the mineral cinnabar. Notable...
Positional Astronomy -- Positional astronomy is the study of the positions of celestial objects. This is the oldest branch of astronomy and dates back to antiquity. Observations of celestial objects are important for religious and astrological purposes, as well as for timekeeping. Ancient structures associated with positional astronomy include: -- Chichn Itz -- The Medicine Wheel -- The Pyramids -- Stonehenge -- The Temple of the Sun The unaided human eye can...
Terrestrial Planet -- A terrestrial planet is a planet that is mostly composed of silicate rocks and may or may not have a relatively thin atmosphere. The term is derived from the Greek word for Earth, so an alternate definition would be those planets that are more Earth-like than not. Terrestrial planets are very different from gas giants, which may or may not have solid surfaces and are composed mostly of hydrogen and helium in various physical states. Only one terrestrial planet,...
The Solar System refers to the area in space that is dominated by our own Sun. It is comprised of the Sun and its associated astronomical objects that are held in its gravitational orbit. The Solar System was formed as a result of the collapse of a giant molecular cloud approximately 4.6 billion years ago. The mass of this system is located almost entirely in the Sun. Apart from the Sun, a high percentage of the remainder of the system’s mass is located in the eight solitary planets that...
