Year Of The Solar System
The Year of the Solar System is a NASA education/public outreach initiative. The year runs October 2010 until August 2012, a Martian year. For each month's topic there are resources for clubs, schools and the general public. The months/topics are: * October 2010: The Journey Begins * November 2010: Birth of Worlds * Dec 2010/Jan 2011: A Family Affair * February 2011: Small Bodies—Big Impacts * March 2011: Ancient Astronomers/Modern Tools: Celebrating Sun-Earth Day * April 2011: Water, Water, Everywhere! * May 2011: Volcanism! * June 2011: Impacts! * July 2011: Rocks in Space * August 2011: Windy Worlds * September 2011: Gravity: It's What Keeps Us Together * October 2011: Moons and Rings: Our Favorite Things * November 2011: Magnetospheres: Planetary Shields * Dec 2011/Jan 2012: Evolving Worlds * February 2012: Far-Ranging Robots * March 2012: Shadows of the Sun * April 2012: Ice! * May 2012: New Data, New Ideas * Jun/Jul 2012: Got Life? * August 2012: Discovering New Worlds The Yea ...

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agencies of the United States government, independent agency of the federal government of the United States, US federal government responsible for the United States's civil list of government space agencies, space program, aeronautics research and outer space, space research. National Aeronautics and Space Act, Established in 1958, it succeeded the National Advisory Committee for Aeronautics (NACA) to give the American space development effort a distinct civilian orientation, emphasizing peaceful applications in space science. It has since led most of America's space exploration programs, including Project Mercury, Project Gemini, the 1968–1972 Apollo program missions, the Skylab space station, and the Space Shuttle. Currently, NASA supports the International Space Station (ISS) along with the Commercial Crew Program and oversees the development of the Orion (spacecraft), Orion spacecraft and the Sp ...

Martian Year
Though no standard exists, numerous calendars and other timekeeping approaches have been proposed for the planet Mars. The most commonly seen in the scientific literature denotes the time of year as the Ecliptic coordinate system, number of degrees on its orbit from the March equinox, northward equinox, and increasingly there is use of numbering the Martian years Mars Year 1, beginning at the equinox that occurred April 1955#April 11, 1955 (Monday), April 11, 1955.). Mars has an axial tilt and a rotation period similar to those of Earth. Thus, it experiences seasons of spring (season), spring, summer, autumn and winter much like Earth. Mars's orbital eccentricity is considerably larger, which causes its seasons to vary significantly in length. A Mars sol, sol, or Martian day, is not that different from an Earth day: less than an hour longer. However, a Mars year is almost twice as long as an Earth year. Sols The average length of a Martian sidereal day is (88,642.663 second ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Science Mission Directorate
The Science Mission Directorate (SMD) of the National Aeronautics and Space Administration (NASA) is one of the six directorates that constitute NASA. Its responsibility is to define and direct research into scientific questions of interest, sharing data acquired by NASA missions with the broader scientific community, sponsoring scientific research, and developing satellites and spacecraft in conjunction with other directorates and with partner organizations for scientific missions. The Science Mission Directorate also sponsors research that both enables, and is enabled by, NASA's exploration activities. The SMD portfolio is contributing to NASA's achievement of the Vision for Space Exploration by striving to: *Understand the history of Mars and the formation of the Solar System. By understanding the formation of diverse terrestrial planets (with atmospheres) in the Solar System, researchers learn more about Earth's future and the most promising opportunities for habitation beyo ...

Astronomy Events
Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry in order to explain their origin and their overall evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, meteoroids, asteroids, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond atmosphere of Earth, Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Egyptian astronomy, Egyptians, Babylonian astronomy, Babylonians, Greek astronomy, Greeks, Indian astronomy, Indians, Chinese astronomy, Chinese, Maya civilization, Maya, and many ancient indigeno ...
