To figure out where asteroids were hitting our planet, B612 used data from a worldwide network of instruments that detect infrasound, low-frequency sound waves traveling through the atmosphere. Such measurements have been used since the 1950s to detect nuclear bomb explosions and can…

Ya gotta be ready…"“Either by the year 2050 we’ve succeeded in developing a sustainable economy, in which case we can then ask your question about 100 years from now, because there will be 100 years from now; or by 2050 we’ve failed to develop a sustainable economy, which means that there will no longer be first world living conditions, and there either won’t be humans 100 years from now, or those humans 100 years from now will have lifestyles similar of those of Cro-Magnons 40,000 years ago, because we’ve already stripped away the surface copper and the surface iron. If we knock ourselves out of the first world, we’re not going to be able to rebuild a first world.”
Say it with me: I WILL NOT GO BACK INTO THE CAVE.
Sustainability is zero sum bullshit. Hair shirt greens can eat my shorts. Either we build up and out, or we fall back and let the next species takeover in a million years.
May an asteroid wipe out any closed mind, human purist, Puritan Earth, false progress civilization. They won’t see it coming anyway. Ahem.
These objects are not catalogued as Mars-crossers in databases such as the Jet Propulsion Laboratory’s online Small-body Database Browser. Instead, they are categorized as Near Earth Objects (NEOs).

Japanese craft to fire “space cannon” into asteroid in search for origins of the universe
Japan’s space agency has successfully test-fired a “space cannon” designed to launch a projectile into an asteroid as part of the search for the origins of the universe.
The device will be aboard the Hayabusa-2 space probe that is scheduled to take off in 2014 and rendezvous with an asteroid identified as 1999JU3 that orbits between Earth and Mars in 2018.
Once in position close to the asteroid, the space cannon will detach itself and remotely fire a 4lb metal projectile into the surface of the miniature planet.
“An artificial crater that can be created by the device is expected to be a small one, a few meters in diameter, but … by acquiring samples from the surface that is exposed by the collision, we can get fresh samples that are less weathered by the space environment or heat,” the Japan Aerospace Exploration Agency said in a statement.
The mother craft will then land close to the crater and use a small rover to collect samples that would have otherwise been below the surface of the asteroid and return to Earth in late 2020. In all, JAXA scientists say the craft will shadow the 2,950-foot-diameter asteroid for around 18 months.
The project has “the potential to revolutionise our understanding of pristine materials essential to understanding the conditions for planet formation and the emergence of life,” JAXA said.
“It can provide important information needed to develop strategies to protect the Earth from potential hazards,” the agency added.
“Moreover, robotic sampling missions to primitive bodies will be pathfinders for … human missions that might use asteroid resources to facilitate human exploration and the development of space.”
Hayabusa-2 is the second project to recover particles from deep space and will build on the success of Hayabusa, which in 2010 gathered surface dust from an asteroid and returned to Earth.
