An unexpected meteorite shower yesterday across three regions of Russia has reportedly caused more than 400 people to seek medical help.
An unexpected meteorite shower yesterday across three regions of Russia has reportedly caused more than 400 people to seek medical help.
Hundreds suffered cuts from broken glass as the meteorites smashed windows in numerous buildings across the Chelyabinsk Region, officials said. “The condition of at least three [people] is considered grave,” an Interior Ministry spokesman said. At least six cities have been hit in three central regions of Russia. Some areas of neighboring Kazakhstan were also affected, Russian state officials confirmed on Friday.
There is something about this story, reported in many Russian news sources, that smells fishy to me. Something happened, and it likely is related to a shower of meteorites, but the images at the link above as well as here and here just don’t look right.
A group of California scientists have proposed a system to vaporize asteroids that threaten Earth.
A group of California scientists have proposed a system to vaporize asteroids that threaten Earth.
In developing the proposal, Lubin and Hughes calculated the requirements and possibilities for DE-STAR systems of several sizes, ranging from a desktop device to one measuring 10 kilometers, or six miles, in diameter. Larger systems were also considered. The larger the system, the greater its capabilities.
For instance, DE-STAR 2 –– at 100 meters in diameter, about the size of the International Space Station –– “could start nudging comets or asteroids out of their orbits,” Hughes said. But DE-STAR 4 –– at 10 kilometers in diameter, about 100 times the size of the ISS –– could deliver 1.4 megatons of energy per day to its target, said Lubin, obliterating an asteroid 500 meters across in one year.
They also propose an even larger system which could “enable interstellar travel.”
Asteroid 2012 DA14 might experience seismic activity when it zips pass the Earth tomorrow.
Asteroid 2012 DA14 might experience seismic activity, an asteroid quake, when it zips pass the Earth tomorrow.
[MIT scientist Richard] Binzel imagines what an astronaut floating alongside such an asteroid might see: “The surface could slowly sway or rock by a few centimeters. Other things to look for would be puffs of asteroid-dust rising from the surface and gentle avalanches on the steepest slopes of craters.” In rare cases, “rubble pile” asteroids might break apart during the encounter and then re-form as Earth recedes into the distance.
A 150 foot wide asteroid will buzz the Earth tomorrow at a distance of only 17,000 miles.
Chicken Little report: A 150 foot wide asteroid will buzz the Earth tomorrow at a distance of only 17,000 miles.
There have been numerous news articles about this fly-by for the last two weeks, all hyping the dangers of an impact that in this case simply won’t happen. A threat of an impact from an asteroid is real and should be dealt with, but the reporting here has at times been somewhat silly. Asteroid 2012 DA14 is not going to hit us as it goes by. All that will happen is that scientists will have take advantage of this opportunity to look at it.

Planetary Resources has released a video showing off the prototype of their Arkyd-100 space telescope.
The competition heats up: Planetary Resources has released a video showing off the prototype of their Arkyd-100 space telescope.
As I noted when this company first appeared, for the foreseeable future they are going to be a manufacturer of space telescopes, not an asteroid mining company. At the same time, they, like Deep Space Industries, are going to drive satellite development towards lower cost and smarter design, which in the long run will make asteroid mining practical and profitable.
The plans and proposed launch schedule of the new asteroid mining company, Deep Space Industries.
The plans and proposed launch schedule of the new asteroid mining company, Deep Space Industries.
They aim to do their work using cubesats, which will keep everything cheap and simple, with the first launches by 2015, and the first sample return missions by 2016. Their new manufacturing technology appears to be a variation of 3D printing, though the descriptions so far released remain vague on details.
We should have even more information later today, after their press conference, aired live on youtube here at 1 pm (eastern).
Another asteroid mining company will announce its plans tomorrow, Tuesday.

As I mentioned earlier today, it is important to maintain a skeptical attitude to each of these new commercial space companies, even as we cheer them on enthusiastically. For example, I am very curious how this company has come through with a “breakthrough process for manufacturing in space.” What could this be, and why has no one thought of it before?
New and better quality images of the asteroid Toutatis from the Chang’e 2 fly-by have been released.

New radar data of Apophis now indicates that its chances of the asteroid hitting the Earth in 2036 is zero.
The sky is not failing: New radar data of Apophis now indicates that its chances of the asteroid hitting the Earth in 2036 is zero.
This data doesn’t eliminate the chance of a collision, only postpones it much farther into the future.
New data from the Herschel Space Telescope suggests that the asteroid Apophis is bigger and less reflective than previous believed.
More Apophis news: New data from the Herschel Space Telescope suggests that the asteroid is bigger and less reflective than previous believed.
Instead of 900 feet across, they now estimate it has a diameter of about 1070 feet. And knowing that the asteroid has a lower albedo means that astronomers will be better able to gauge the effect of solar radiation on Apophis’s orbit.
How to watch the asteroid Apophis as it makes its not-so-close approach to Earth today.
On Wednesday Apophis will pass the Earth at a distance of 9 million miles, allowing astronomers to gather more data about this asteroid’s orbit and composition.
On Wednesday Apophis will pass the Earth at a distance of 9 million miles, allowing astronomers to gather more data about this asteroid’s orbit and composition.
Having crossed outside Earth’s orbit, Apophis will appear briefly in the night-time sky. Wednesday 9 January will afford astronomers the rare opportunity to bring a battery of telescopes to bear: from optical telescopes to radio telescopes to the European Space Agency’s Infrared Space Observatory Herschel. Two of the biggest unknowns that remain to be established are the asteroid’s mass and the way it is spinning. Both of these affect the asteroid’s orbit and without them, precise calculations cannot be made.

An ion test engine has set a new record for continuous operation.
An ion test engine has set a new record for continuous operation.
The NEXT ion thruster is one of NASA’s latest generation of engines. With a power output of seven kilowatts, it’s over twice as powerful as the ones used aboard the unmanned Dawn space probe. Yet it is simpler in design, lighter and more efficient, and is also designed for very high endurance. Its current record of 43,000 hours is the equivalent of nearly five years of continuous operation while consuming only 770 kg (1697.5 lbs) of xenon propellant.
This engine will make the unmanned exploration of the asteroid belt extremely easy and practical.
