1. NASA-funded robotic sub makes final dive to reach bottom of Earth's deepest sinkhole
   05-15-2007 · EurekAlert!
   Scientists from the University of Texas at Austin's Jackson School of Geosciences and other institutions begin the final leg of a five-year, NASA-funded mission to reach the bottom of Cenote Zacatón in Mexico, the world's deepest known sinkhole, hoping to learn about Zacatón's geology, geothermal vents and forms of life. Previous expeditions tested the robotic probe that makes the dive, DEPTHX, designed to explore for life in extreme regions on Earth and in outer space.

3. Prototype space probe prepares to explore Earth's deepest sinkhole
   03-07-2007 · EurekAlert!
   Scientists return this week to the world’s deepest known sinkhole for tests of a NASA-funded robot called DEPTHX, designed to survey and explore for life in one of Earth’s most extreme regions and potentially in outer space. DEPTHX's technology could aid future space probes of Europa, where scientists believe deep holes in the ice could hold extraterrestrial life.

5. NASA's New Mars Camera Gives Dramatic View Of Planet
   09-30-2006 · ScienceDaily
   Mars is ready for its close-up. The highest-resolution camera ever to orbit Mars is returning low-altitude images to Earth from NASA's Mars Reconnaissance Orbiter. Rocks and surface features as small as armchairs are revealed in the first image from NASA's Mars Reconnaissance Orbiter since the spacecraft maneuvered into its final, low-altitude orbital path. The imaging of the red planet at this resolution heralds a new era in Mars exploration.

   The sharpest image ever taken of the large "grand design" spiral galaxy Messier 81 is being released today. The image, constructed from a series of images taken with NASA/ESA Hubble Space Telescope, is among the largest ever released. Messier 81 is one of the brightest galaxies that can be seen from the Earth.

7. New view of doomed star
   06-20-2007 · EurekAlert!
   A new composite image of the Eta Carinae from NASA's Chandra X-ray Observatory and Hubble Space Telescope shows the remnants of a massive eruption from the star during the 1840s. Eta Carinae is a mysterious, extremely bright and unstable star located a mere stone's throw -- astronomically speaking -- from Earth at a distance of only about 7500 light years. The star is thought to be consuming its nuclear fuel at an incredible rate, while quickly drawing closer to its ultimate explosive demise.

8. Discovery set for launch
   12-07-2006 · European Space Agency (ESA)
   Space Shuttle Discovery and her seven crewmembers are ready for launch tonight at 03:35 CET (02:35 UT). NASA is keeping a keen eye on the weather over the Cape as a cold front moves through the area. For now the countdown to launch continues.

   The seven astronauts, including ESA astronaut Christer Fuglesang, are undergoing final preparations, including a final pre-launch medical exam. The crew is scheduled to suit up at 23:15 CET (22:15 UT), after which they will depart the crew quarters for the drive to the launch pad.

   NASA TV will start live coverage from 23:30 CET (22:30 UT). For more about the Celsius Mission, visit http://www.esa.int/celsius

10. Aerosol pollution slows down winds and reduces rainfall
    01-22-2007 · EurekAlert!
    Near-surface winds provide a renewable source of clean energy and evaporate water, helping rain clouds to build up. But aerosolized particles created from vehicle exhaust and other contaminants can accumulate in the atmosphere and reduce the speed of winds closer to the Earth's surface, which results in less wind power available for wind-turbine electricity and also in reduced precipitation, according to a study by Stanford and NASA researchers.
