Where were you when the dinosaurs needed you?

Recent events have certainly highlighted the risk of asteroid strikes. There was the 15-meter (49-foot) meteor that blew up an approximated 12 miles over Chelyabinsk, Russia, on Feb. 15, harmful buildings and wounding even more than 1,000 people.

That same day, the 45-meter (148-foot) asteroid 2012 DA14 passed within 17,200 miles of Earth. If that effect had taken place, it would have been the equivalent of 160 Hiroshima nuclear bombs. You want to safeguard the Earth from asteroids? Where were you when the dinosaurs needed you?

A 50-foot large, 10,000-ton meteor that stuffs triple the force of the nuke dropped on Hiroshima is absolutely nothing to discount. In the grand scheme of things, the meteor that struck Chelyabinsk, Russia, is a cosmological runt. Area rocks as much as 100 feet across are estimated to strike every hundred years approximately and those like the 160-foot diameter Tunguska meteor of 1908 struck maybe when a century. Though rare, these "killer asteroids" can wipe out a city the size of Moscow and eliminate upwards of 30,000 in an instant.

While the primary business of Planetary Resources is to prospect and mine asteroids with high concentrations of water and precious metals, the company views that this economically driven activity will also aid in shielding Earth from possibly harmful asteroids. Space mining start-up Planetary Resources is promising its outer space technology will soon help detect and define potentially hazardous asteroids prior to they get any close to our world. Asteroid miner revealed that its Arkyd-100 Low Earth Orbit spacecraft will have the capacity and infrastructure for intercepting and deflecting possibly rogue items.

Experts estimate there are over 500,000 near-earth asteroids the size of DA14 or larger. A body of really comparable characteristic to the DA14 most likely strikes the Earth every 1000 years or so, and does so with sufficient kinetic energy to damage a city. That is why specialists are closely tracking 434 of those bodies, which are huge enough and come close enough our world to be of prospective future concern, said Planetary Resources. While none of these posture any significant danger today, the asteroid mining firm cautioned enhanced surveillance is required.

When the University of Hawaii's brand-new meteor tracking systems come online, we'll be able to forecast meteor strikes as properly as we do storms. It's called the ATLAS (Asteroid Terrestrial-impact Last Alert System) and includes a pair of observatories located about 60 miles apart, each geared up with four, 10-inch telescopes equipped with 100 MP cameras.

Together, these observatories would scan the visible sky two times an evening. That item is flagged for further examination if an item moves in relation to its formerly tape-recorded area on any given night. The telescopes, though reasonably small, will be sensitive adequate to find and approximate an incoming threat's precise effect place and time, to the second.

ATLAS is expected to find half of the 160-foot asteroids in the solar system and two-thirds of the 460-foot world killers that are believed to be floating around us. This would offer individuals in the effect area anywhere from a few days to a couple of weeks to evacuate, relying on the size of the rock.
And though the system's detection rate will likely never ever top 75 percent, it will coordinate with various other space-based comet catchers like the NEO and Pan-STARRS telescopes, which peer more however over a smaller sized swath of sky, to optimize their insurance coverage.
