Engineering researcher seeks answers to asteroid deflection
An Asteroid Deflection Research Center (ADRC) has been established on the Iowa State campus to bring researchers from around the world to develop asteroid deflection technologies. The center was signed into effect in April by the Office of the Executive Vice President and Provost. (2008-05-28)

Foot-dragging Mars rover finds Yellowstone-like hot spring deposits
Deposits of nearly pure silica discovered by the Mars Exploration Rover Spirit in Gusev Crater formed when volcanic steam or hot water (or maybe both) percolated through the ground. (2008-05-23)

Artificial intelligence boosts science from Mars
Artificial intelligence (AI) being used at the European Space Operations Centre is giving a powerful boost to ESA's Mars Express as it searches for signs of past or present life on the Red Planet. (2008-04-30)

Missions to Mars
The European Space Agency (ESA) has chosen the GSI accelerator facility to assess radiation risks that astronauts will be exposed to on a Mars mission. (2008-04-15)

International team of scientists discover clue to delay of life on Earth
Scientists from around the world have reconstructed changes in Earth's ancient ocean chemistry during a broad sweep of geological time, from about 2.5 to 0.5 billion years ago. (2008-03-27)

Brain stem cells sensitive to space radiation
Cold Spring Harbor Laboratory (CSHL) scientists recently led a team of researchers to study potential effects of space radiation on astronauts. (2007-12-12)

Solving solar system quandaries is simple: Just flip-flop the position of Uranus and Neptune
Quick: What's the order of the planets in the solar system? Need a little help? Maybe the following mnemonic rings a bell: "My Very Educated Mother Just Served Up Nine Pizzas." It's useful for remembering the order of the planets today, but it wouldn't have been as useful in the past, and not just because the International Astronomical Union demoted Pluto to "dwarf planet" last year. The reason this mnemonic wouldn't have worked is because the planets weren't always in the order they are today. Four billion years ago, early in the solar system's evolution, Uranus and Neptune switched places. (2007-12-12)

Helium isotopes point to the best sources of geothermal energy
With fossil fuel sources depleting and global warming on the rise, exploring alternative means of power for humans is a necessary reality. (2007-12-03)

NIST posts online database of cryogenic materials properties
In response to numerous inquiries from academia, industry, and other government labs, the National Institute of Standards and Technology (NIST) recently published a new database on the properties of solid materials at temperatures ranging from cryogenic (as low as 4 K, which is -269 degrees C or -452 degrees F) to room temperature.

Space Exploration 3.0 about to begin
Space exploration is about to enter a third age where nations will cooperate to explore the solar system. (2007-11-05)
