Academics found a eureka
moment as the University of California. Book Club points to their only problem lies inside the 'Higgs Model' as it explain bright lights only part of the process as swarm satellites by
Chinese seems more of a tackle. Problems lies within the planetary magnetic phasing.

How asteroid 2012 DA14 looked in a long-exposure image taken from Earth: If it had struck it would have exploded with one thousand times the force of the atom bomb dropped on Hiroshima in 1945. It could propel a 10-ton spacecraft at near the speed of light, allowing interstellar exploration to become a reality without waiting for science fiction technology such as 'warp drive' to come along, said Professor Lubin acting with minor defense might be of ‘some comfort as studies of their fields’ and their magnetic structures making these celestial objects attraction to planet fazes. Scalabile this plot shows DE-STAR laser power and spot diameter versus DE-STAR array size. The DE-STAR system is modular and can be built up in sections each of which is immediately operational The researchers say recent and rapid developments in highly efficient conversion of light to electrical power have made such advances a possibility today when just 20 years ago they would have appeared impossible.
An asteroid big enough to destroy London skimmed past the Earth at just after 7pm on Friday night. The flyby by the 150ft, 130,000 ton chunk of space rock was the closest shave for an object of this size since records began. Although scientists said there was little chance of asteroid 2012 DA14 hitting our planet, if it did, it would have inflicted 1,000 times more damage than the atomic bomb dropped on Hiroshima. Its closest approach - passing within 17,000 miles, which is closer than some satellites - was at 7.25pm GMT. The flyby occurred just hours after a much smaller meteor exploded above Russia's Ural Mountains. Astronomers said the two events were merely a coincidence and that the objects were travelling in opposite directions.
DE-STAR is designed
to harness the power of the Sun and convert it into a massive phased array of
laser beams. After Earth's close shave with asteroid 2012 DA14 on 15-2-2013 the unexpected meteorite explosion which injured 1,000 Russians that
morning.
With attention has turned to technology which could be used to defend our
planet. The 130,000 ton, 150ft-wide lump of space rock hurtled past at
17,400mph - eight times as fast as a bullet from a high-powered sniper rifle -
making its closest approach at 7.25pm on Friday evening. If it had struck our
planet it would have exploded with one thousand times the force of the atom
bomb dropped on Hiroshima in 1945. Extinction-level event size.
Radar images of
the three-mile-long asteroid Toutatis captured by NASA's Goldstone Solar System
Radar on December 12 and 13 as it passed the Earth at a distance of some
4.3million miles Gary Hughes, a professor at Cal Poly, who contributed to the
research, said: 'This system is not some far-out idea from Star Trek.'All the
components of this system pretty much exist today. Maybe not quite at the scale
that we'd need – scaling up would be the challenge – but the basic elements are
all there and ready to go.
'We just need to put them into a larger system to be effective, and once the system is there, it can do so many things.' Indeed, the researchers say that aside from vaporising extinction-level event size asteroids, the DE-STAR system has a number of other potential uses - even as a spaceship propulsion system. Professor Hughes and UC Santa Barbara physicist Philip Lubin calculated the requirements and possibilities for DE-STAR systems of several sizes, ranging from a desktop device to one measuring six miles in diameter. The larger the system, the greater its capabilities, they said. For example, DE-STAR 2 – at 100m in diameter, about the size of the International Space Station ‘could start nudging comets or asteroids out of their orbits,' Professor Hughes said.

Sun-powered lasers
could protect Earth from any more asteroids judged to be flying too close, a
new study claims. U.S. researchers have outlined a plan for solar powered space defenses which could vaporize an asteroid as big as the one which flew past
Earth on 15-2-2013 in about 60 minutes.
The same system could destroy
asteroids 10 times larger in about a year, with evaporation starting at a
distance as far away as the Sun, the researchers claim. In the run up to the
close shave - an event which occurs roughly once every 40 years - astronomers
were keen to point out that their calculations showed little chance of asteroid
2012 DA14 actually hitting our planet.
But in the event a similar or bigger
interloper is spotted on a collision - an event thought to happen every 1,200
years or so with their powerful crash.This plot shows time to evaporate an Appolipse-like
asteroid versus its diameter, versus several laser power levels. The baseline
DE-STAR 4 system has approximately 100 Giga-watts of laser power.
But DE-STAR 4
– at 10km in diameter, about 100 times the size of the ISS – could deliver 1.4
megatons of energy per day to its target, said Professor Lubin, obliterating an
asteroid 500m across in one year.Such a sized system
could also accelerate interplanetary travel far beyond what is possible with
the chemical propellant rockets used today, Professor Lubin claims. It could
also power advanced ion drive systems for deep space travel, he said. Able to
engage multiple targets and missions at once, he claimed, DE-STAR 4 'could
simultaneously evaporate an asteroid, determine the composition of another, and
propel a spacecraft.
'Larger still, DE-STAR 6 could enable interstellar travel
by functioning as a massive, orbiting power source and propulsion system for
spacecraft. 'Our proposal assumes a combination of baseline technology – where
we are today – and where we almost certainly will be in the future, without
asking for any miracles,' said Professor Lubin. 'We've really tried to temper
this with a realistic view of what we can do, and we approached it from that
point of view.
'It does require very careful attention to a number of details,
and it does require a will to do so, but it does not require a miracle.' Professor
Hughes added: 'These are not just back-of-the-envelope numbers. They are
actually based on detailed analysis, through solid calculations, justifying what
is possible. It's all available under current theory and current
technology. 'There are large asteroids and comets that cross the Earth's orbit,
and some very dangerous ones going to hit the Earth eventually. 'Many have hit
in the past and many will hit in the future. We should feel compelled to do
something about the risk. Realistic solutions need to be considered, and this
is definitely one of those.
Professor Lubin, who began work on DE-STAR a year
ago, said: 'We have to come to grips with discussing these issues in a logical
and rational way. 'We need to be proactive rather than reactive in dealing with
threats. Sun-powered asteroid-busting lasers. This Is described as a directed energy
orbital defense system.
There are more than 8000 satellites in Earth orbit approximately a scan track their orbit by Google and be viewed by telescope as where they have been built, anybody can do this as their a tag on the side of most objects this will show their details. In space approximately 560 of those in orbit are actually operational satellites in position. Another option from book club is remaking these with either International Space Station or other space stations could be used as valuable new way of re booting a new ‘Earth Defense as Space Shuttle has proven this with Hubble telescope'.
