    Kansas Legislator Proposes Bill to Outlaw Sustainability Education

    A bill has been introduced in the Kansas legislature this week that would prohibit the promotion of sustainability. Here is a link to the one-page bill: http://www.kslegislature.org/li/b2013_14/measures/documents/hb2366_00_0000.pdf. See report on Bloomberg News.

    Earth's Center Is 1,000 Degrees Hotter Than Previously Thought, Synchrotron X-Ray Experiment Shows

    Scientists have determined the temperature near the Earth’s center to be 6000 degrees Celsius, 1000 degrees hotter than in a previous experiment run 20 years ago. These measurements confirm geophysical models that the temperature difference between the solid core and the mantle above, must be at least 1500 degrees to explain why the Earth has a magnetic field. For more information about this study, see the press release from the European Synchrotron Radiation Facility.

    Ocean Volcanic Rocks Contain Samples of Recycled Crust

    Scientists have long believed that lava erupted from certain oceanic volcanoes contains materials from the early Earth’s crust. But decisive evidence for this phenomenon has proven elusive. New research from a team including Carnegie’s Erik Hauri demonstrates that oceanic volcanic rocks contain samples of recycled crust dating back to the Archean era 2.5 billion years ago. Their work is published in Nature. Oceanic crust sinks into the Earth’s mantle at so-called subduction zones, where two plates come together. Much of what happens to the crust during this journey is unknown. Model-dependent studies for how long subducted material can exist in the mantle are uncertain and evidence of very old crust returning to Earth’s surface via upwellings of magma has not been found until now. For more information about these results, see the press release from the Carnegie Institution.

To the Moon!
News story originally written on December 9, 1997

The first NASA lunar mission in 25 years will be launched soon after the New Year begins. The Lunar Prospector spacecraft will be launched on January 5, 1998. After only a month's travel time to the Moon, it will begin making the first complete maps of the lunar surface.

The Lunar Prospector's mission will be a profound one. Over 75% of the Moon's surface is not mapped out in detail. In addition, there are several mysteries about the Moon's composition and internal processes. The Lunar Prospector will provide information about all of these inconsistencies by mapping out the lunar surface composition, and gravity/magnetic fields. In addition, the craft will try to detect any kind of volatile activity on the Moon, and detect whether or not the Moon's poles contain water ice.

The Lunar Prospector's mission is expected to last one year, and will have a polar orbit about the Moon. The craft has a mass of 660 pounds, and is 4.5 feet high by 4 feet in diameter.

Data from this mission could help scientists plan a potential lunar base and develop theories of the formation of the solar system.
