NASA is nervous about sending astronauts to Mars because exposure to the wind of high-energy particles streaming from the sun could indeed prove deadly. But a team of researchers at the Rutherford Appleton Laboratory (RAL) near Oxford, UK, have shown that a magnet no wider than your thumb can deflect a stream of charged particles like those in the solar wind. It gives new life to an old idea about shielding spacecraft, and might just usher in a new era of space travel.

There's gridlock in orbit. More than 400 telecommunications satellites, plus an indeterminate number of retired, failed, and secret spacecraft, occupy a narrow band of space some 35,000 kilometers above Earth's equator. Now, researchers have found a way to alleviate the congestion: attaching solar sails to satellites that would propel them 10 to 30 kilometers north or south of the standard orbit.

An in-depth analysis of ten climate indicators all point to a marked warming over the past three decades, with the most recent decade being the hottest on record, according to the latest of the U.S. National Atmospheric and Oceanic Administration's annual "State of the Climate" reports, which was released Wednesday. Reliable global climate record-keeping began in the 1880s.
