We live in the age of life-hacking. The concept, which denotes a kind of upbeat, engineer-like approach to maximizing one’s personal productivity, first entered the mainstream lexicon in the mid-2000s, via tech journalists, the blogosphere, and trendspotting articles with headlines like “Meet the Life Hackers.” Since then the term has become ubiquitous in popular culture—just part of the atmosphere, humming with buzzwords, of the Internet age.
Variations on a blog post called “50 Life Hacks to Simplify Your World” have become endlessly, recursively viral, turning up on Facebook feeds again and again like ghost ships. Lifehacker.com, one of the many horses in Gawker Media’s stable of workplace procrastination sites, furnishes office workers with an endless array of ideas on how to live fitter, happier, and more productively: Track your sleep habits with motion-sensing apps and calculate your perfect personal bed-time; learn how to “supercharge your Gmail filters”; oh, and read novels, because it turns out that “reduces anxiety.” The tribune of life hackers, the author and sometime tech investor Timothy Ferriss, drums up recipes for a life of ease with an indefatigable frenzy, and enumerates the advantages in bestselling books and a reality TV show; outsource your bill payments to a man in India, he advises, and you can enjoy 15 more minutes of “orgasmic meditation.”

Earth is surrounded by a cloud of more than half a million pieces of space junk, from bus-size spent rocket stages to tiny flecks of paint. Orbiting at breakneck speeds, every last bit poses grave dangers — and means huge insurance premiums — for operational satellites, and it threatens the International Space Station, too. Every time two orbiting objects collide, they break up into thousands more pieces of debris.
To combat this growing headache, Swiss scientists and engineers have announced the launch of CleanSpace One, a project to build the first in a family of “janitor” satellites that will help clean up space.
To be launched as soon as three to five years from now, CleanSpace One will rendezvous with one of two defunct objects in orbit, either the Swisscube picosatellite, or its cousin TIsat, both 1,000 cubic centimeters (61 cubic inches) in size. When the janitor satellite reaches its target, it will extend a grappling arm, grab it and then plunge into Earth’s atmosphere, burning up itself and the space junk during re-entry.

Paul Scott Anderson at Universe Today: As “we” continue to explore farther out into our solar system and beyond, the question of habitation or colonization inevitably comes up. Manned bases on the Moon or Mars for example, have long been a dream of many. There is a natural desire to explore as far as we can go, and also to extend humanity’s presence on a permanent or at least semi-permanent basis. In order to do this, however, it is necessary to adapt to different extreme environments. On the Moon for example, a colony must be self-sustaining and protect its inhabitants from the airless, harsh environment outside.
Mars, though, is different. While future bases could adapt to the Martian environment as well, there is also the possibility of modifying the surrounding environment instead of just co-existing with it. This is the process of terraforming – essentially trying to tinker with Mars’ atmosphere and environment to make it more Earth-like. Although still a long ways off technologically, terraforming the Red Planet is seen as a future possibility. Perhaps the bigger question is, should we? Continue HERE
