If all goes well, tomorrow morning at approximately 10:02 a.m. Eastern time (GMT-5), NASA will launch its newest rover named Curiosity from Florida's Cape Canaveral, headed on a nine-month trip to the planet Mars. The $2.3 billion mission will send a capsule into the Martian sky in August of 2012. After decelerating in the atmosphere, a series of entry events will quickly take place, ending with a rocket-powered sky crane lowering the rover gently to the surface. Curiosity is a beast of a rover, weighing one ton, measuring ten feet long by seven feet tall (at the top of the mast), and powered by a plutonium-238 fueled electrical generator. The rover carries ten instruments, including several high-resolution cameras, and a laser-induced breakdown spectroscopy instrument called ChemCam that can vaporize tiny amounts of minerals and analyze their components. If all goes according to plan, Curiosity is scheduled for a stay on Mars of about 668 Martian sols, or nearly two Earth years, starting in Gale crater. Researchers hope to use the tools on Curiosity to study whether the area in Gale crater has had environmental conditions favorable for supporting microbial life and for preserving clues about whether life existed. I will update this entry with more photos later, after the launch takes place. [34 photos]

THE Japanese maker of an exoskeleton robot suit to assist walking on Monday unveiled a model that could help nuclear workers weighed down by heavy anti-radiation vests in contaminated zones.
On July 13, 2010, this cargo container arrived in Genoa, Italy. It was emitting torrents of radiation. No one knew what was inside. And no one knew what to do next.
Only a tiny fraction of the brain is dedicated to conscious behavior. The rest works feverishly behind the scenes regulating everything from breathing to mate selection. In fact, neuroscientist David Eagleman of Baylor College of Medicine argues that the unconscious workings of the brain are so crucial to everyday functioning that their influence often trumps conscious thought. To prove it, he explores little-known historical episodes, the latest psychological research, and enduring medical mysteries, revealing the bizarre and often inexplicable mechanisms underlying daily life.
An article at the moviemaking technology website Creative Cow reports that the three major manufacturers of motion picture film cameras - Aaton, ARRI and Panavision - have all ceased production of new cameras within the last year, and will only make digital movie cameras from now on. As the article's author, Debra Kaufman, poignantly puts it, "Someone, somewhere in the world is now holding the last film camera ever to roll off the line.
The story of the brain begins in the ancient oceans, long before the first animals appeared. The single-celled organisms that swam or crawled in them may not have had brains, but they did have sophisticated ways of sensing and responding to their environment. "These mechanisms are maintained right through to the evolution of mammals," says Seth Grant at the Wellcome Trust Sanger Institute in Cambridge, UK. "That's a very deep ancestry.
The KH-9 HEXAGON, often referred to by its popular nickname "Big Bird," lived up to its legendary expectations. As large as a school bus, the KH-9 HEXAGON carried 60 miles of high resolution photographic film for space surveillance missions.
Screw powerpoint. Cool kids use html5 for presentations.
For Bezos, the founder of Amazon.com, the clock is not just the ultimate prestige timepiece. It's a symbol of the power of long-term thinking. His hope is that building it will change the way humanity thinks about time, encouraging our distant descendants to take a longer view than we have.
Recently, someone asked Reddit for a list of the best science fiction books of all time. Being a fan of sci-fi, and wanting to expand my own reading list, I thought it would be helpful to tally the results and preserve them here for future reference.
