To Boldly Stick
NASA’s Martian rover Spirit will officially rove no more. After being stuck in a sand pit on Mars for the last 10 months, it has been announced that the aging shuttle will not be moved.
"The Martian rover Spirit will rove no more. Officials at the National Aeronautics and Space Administration announced Tuesday that the Spirit, mired in a sand pit for the last 10 months, would remain there forever. But the officials said they were hopeful that the Spirit would continue life as a stationary science station — if it survives the upcoming Martian winter. ‘This is not a day of mourning for Spirit,’ Douglas McCuistion, director of the Mars exploration program at NASA headquarters in Washington, said during a telephone news conference. In March, the Spirit’s six wheels broke through a hard crust into sandy material and became stuck. In November, as it was attempting to drive out, its right rear wheel failed. The right front wheel had stopped turning four years ago. Officials decided that even if the Spirit could extricate itself, with two bad wheels, its best driving days were past. The Spirit, designed to last three months, has survived for more than six years. ‘It’s kind of a poignant moment for us,’ said Steven W. Squyres, the mission’s principal investigator."
How a cataclysm worse than what killed the dinosaurs destroyed 90 percent of all life on Earth.
While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.
A new study discovers the “liking gap” — the difference between how we view others we’re meeting for the first time, and the way we think they’re seeing us.
We tend to be defensive socially. When we meet new people, we’re often concerned with how we’re coming off. Our anxiety causes us to be so concerned with the impression we’re creating that we fail to notice that the same is true of the other person as well. A new study led by Erica J. Boothby, published on September 5 in Psychological Science, reveals how people tend to like us more in first encounters than we’d ever suspect.
Using advanced laser technology, scientists at NASA will track global changes in ice with greater accuracy.
Leaving from Vandenberg Air Force base in California this coming Saturday, at 8:46 a.m. ET, the Ice, Cloud, and Land Elevation Satellite-2 — or, the "ICESat-2" — is perched atop a United Launch Alliance Delta II rocket, and when it assumes its orbit, it will study ice layers at Earth's poles, using its only payload, the Advance Topographic Laser Altimeter System (ATLAS).
