Mars Lander Headed for “7 Minutes of Terror” Sunday

Mars Lander Headed for “7 Minutes of Terror” Sunday

After years of planning followed by a ten-month journey, the Mars Phoenix Lander is slated to touch down Sunday near the red planet’s north pole. If successful, the probe will be the first lander to reach a Martian pole and the first to actually touch the planet’s water ice.

What’s more, it could settle the debate over whether Mars was once suitable for life.

As Phoenix closed in on the last miles of its journey, NASA scientists were gearing up for the “seven minutes of terror” that could make or break the U.S. $420-million mission.

Italy to reverse policy and build nuclear power stations: minister

The Italian government said Thursday it would begin building nuclear power stations, reversing a 20-year ban in an initiative likely to spark strong resistance and take a long time to come to fruition.

“During the term of this parliament, we will lay the first stone for the construction in our country of a group of new-generation nuclear power stations,” Economic Development Minister Claudio Scajola told the Italian employers’ federation Confindustria.

“We can no longer avoid an action plan for a return to nuclear power,” he said, recalling a campaign pledge by Italy’s newly named right-wing prime minister, Silvio Berlusconi, to take such a step.

A Test of the Copernican Principle

The Copernican principle states that the Earth is not the center of the universe, and that, as observers, we don’t occupy a special place. First stated by Copernicus in the 16th century, today the idea is wholly accepted by scientists, and is an assumed concept in many astronomical theories.

However, as physicists Robert Caldwell of Dartmouth College in Hanover, New Hampshire, and Albert Stebbins of Fermilab in Batavia, Illinois, point out, the Copernican principle has never been confirmed as a whole. In a recent paper published in Physical Review Letters called “A Test of the Copernican Principle,” the two researchers set out to prove the 500-year-old principle using observations of the cosmic microwave background (CMB).
