SpaceTT: Asteroid 2012 DA14 to make closest pass to Earth today at 2:24 PM US EST - hope it doesn't screw with us

Asteroid 2012 DA14, a chunk of space rock roughly the size of a football field, will make the closest pass to Earth ever recorded of a previously known object. At around 2:24 PM US EST the asteroid will pass Earth within 17,200 miles of our atmosphere.

This close pass comes hot on the heels of an unrelated massive meteorite exploding over Russia yesterday. The meteorite passed over a remote part of Russia and exploded over the town of Chelyabinsk, and injured 500 people when its shock wave shattered the glass in surrounding buildings. You can hear the massive explosion in the video below.

 

 

NASA scientists say that the two events are most likely unrelated, and there is zero chance of Asteroid 2012 DA14 hitting Earth. Those interested will be able to observe tonight's flyby by watching a series of webcasts being held by NASA and broadcast on Space.com (Source #2). Personally I will be outside with my 10" Schmidt Newtonian telescope trying to get a fleeting glimpse of the object.

University of Southern California shows off battery featuring silicon nanowires, holds 3x the energy, charges in 10 minutes

I really can't wait for the day when I can buy a new smartphone with a week-long battery, but it looks like the University of Southern California are working on it, almost like they're reading my thoughts.

This technology uses porous, flexible silicon nanowires for the anodes in a lithium-ion battery that would provide the high capacity, fast recharding and low costs that come with the silicon, but without the weaker previous attempts that relied on simpler silicon plates.

 

This would, in a best case scenario, provide us with triple the capacity of today's best batteries, a full recharge in 10 minutes and more than 2,000 charging cycles. This is where I say "shut up and take my money", but the money hitting my screen and falling onto my keyboard is doing nothing. To finish, researchers have estimated that there should be products hitting consumers' hands with silicon-sporting lithium-ion packs in two to three years, which isn't too long at all.

LHC will be down for next two years undergoing maintenance and upgrades

For those science junkies that were disappointed when the Large Hadron Collider didn't manage to end the world by creating black holes, you'll be getting another chance in two years. The LHC will be down for the next two years so that it can undergo maintenance and upgrades to bring it back to peak efficiency.

The device will eventually make its way back online sometime in 2014. At that time, it's expected that the particle accelerator will be operating at up to 14 trillion electron-volts, double the energy it was running at in 2011. Part of the reason the LHC hasn't achieved higher energies yet is due to the helium gas explosion which damaged and delayed the project.

 

This maintenance period will be used to fix that damage, perform maintenance and upgrade the detectors, electronic shielding, and ventilation system.

Your next house could be 3D-printed, would take just three weeks to build

3D printers are the new everything right now, where we've heard about moon bases being 3D-printed, buildings being 3D-printed and even stem cells - what next? Houses. Yes, houses.

 

TweakTown image news/2/8/28517_01_your_next_house_could_be_3d_printed_would_take_just_three_weeks_to_build.jpg

 

A London-based design firm, Softkill, has just talked about their entry into the rat race that is 3D-printed houses, with a structure they claim would take just three weeks to build. From the picture above, it looks like a million spiders have crawled in and just spun a house out of their webs, but this is all part of what Softkill call their ProtoHouse, and will reach the prototype stage by the middle of the year.

 

During an interview with Dezeen, Softkill's Gilles Retsin didn't like the idea of their rival project by Universe Architecture, where he said:

 

We actually don't even consider that a 3D-printed building, because he is 3D printing formwork and then pouring concrete into the form. So it's not that the actual building is 3D printed.

SpaceTT: Astronomers ask public to help name Pluto's two new moons

Recently two more moons were discovered around the former planet Pluto, bringing the total count up to five. Dubbed P4 and P5 for obvious reasons, these two new moons have brought new understanding on how the dwarf planet fits into our solar system.

 

TweakTown image news/2/8/28444_1_astronomers_ask_public_to_help_name_pluto_s_2_new_moons.jpg

 

SETI, the institute that is more so known for its research into discovering alien life, has decided to spice up the bland names given to the newly discovered moons. Beginning today SETI will hold a contest to name the moons. The institute is asking the public to either pick from a list or write in names associated with Hades of Greco-Roman mythology fame.

 

A list of the pre-selected names can be found on SETI's website, which I have listed below in the Source #2 link below. I decided to go with two common names myself - Heracles and Persephone.

NASA's Curiosity rover drills into Mars' surface, is feeling a bit thirsty

NASA's Curiosity rover, when not checking in on Foursquare, is discovering new things all the time - this time, it is digging into Mars' surface looking for water.

 

TweakTown image news/2/8/28436_05_nasa_s_curiosity_rover_drills_into_mars_surface_is_feeling_a_bit_thirsty.jpg

 

Curiosity whipped its drill out and started chewing into the bedrock of Mars, digging a 0.63- by 2.5-inch hole. We won't find out the results to its discovery for a few days yet as the rover will analyze its findings, hoping to find water. The picture above shows the first ever hole drilled into the red planet, and while it may seem like it was easy, it really wasn't. Louise Jandura, Chief Engineer of the rover's sample system says:

 

Building a tool to interact forcefully with unpredictable rocks on Mars required an ambitious development and testing program. To get to the point of making this hole in a rock on Mars we made eight drills and bored more than 1,200 holes in 20 types of rock on Earth.

SpaceTT: NASA Astronauts to "hangout" in Google+ and answer your questions from space

Let's face it; most of our readers would love the chance to talk to an astronaut who is orbiting the earth inside the international space station. In fact, Americans have long been fascinated with communicating with astronauts while in space.

 

TweakTown image news/2/8/28414_1_spacett_nasa_astronauts_to_hang_out_in_google_and_answer_your_question.jpg

 

NASA has announced that U.S. astronauts Kevin Ford and Tom Marshburn along with Chris Hadfield of the Canadian Space Agency will be fielding questions live during a Google+ hangout that will take place on February 22nd at 11AM US Eastern time.

 

It is becoming pretty common for astronauts to communicate with the public during their extended trips on the International Space Station. Recently Hadfield hosted an AMA on Reddit, and has had a back and forth series of tweets with William Shatner of Star Trek fame. I hope to be one of the lucky people to get a question answered during the hangout. Maybe I will see you there!

Curiosity uses last tool, NASA testing the rover's drill

If you've been following the progress of the Curiosity rover on Mars, there's a bit of new information to add to your trivia knowledge. NASA has officially used the last tool on Curiosity in a test to make sure it is functioning. Curiosity is equipped with a drill capable of drilling into rocks to retrieve samples from inside.

 

TweakTown image news/2/8/28398_1_curiosity_uses_last_tool_nasa_testing_the_rover_s_drill.jpg

 

The ability to drill into rocks is an important one as these stones record the history of the planet millions and billions of years at a time. NASA is currently testing the drill to make sure everything is functioning properly. After positive results come back, NASA will order Curiosity to drill further into this rock to obtain samples.

 

The samples will then be analyzed in Curiosity's on-board chemistry lab to determine their chemical and mineral composition. The hope is that the results will show that life either existed previously or could have existed.

Forget to charge your phone? Just use your morning cup of coffee to give it a boost

We have all done it before; you get to work and realize that you forgot to charge your phone the night before. Now you can forget plugging in that USB cable for a battery boost, because the Epiphany One Puck will charge your phone by recycling the heat in your beverage into electricity.

 

 

The technology behind the Epiphany One Puck is quite simple actually. A Peltier is used to convert the heat into electric energy by thermo-electric-cooling. Basically as one side of the Peltier gets hot, the other side cools down and electrons are shed, generating electricity.

 

TweakTown image news/2/8/28387_1_forget_to_charge_your_phone_just_use_your_morning_cup_of_coffee_to_give_it_a_boost.jpg

 

We have seen this technology before and in fact it is used in custom PC cooling setups all the time. Cooler Master even built an entire CPU cooler based on a TEC. The company behind the Epiphany One Puck is about to wrap up their quite successful Kickstarter, so if you want one you better hurry quick to get in on the savings.

SpaceTT: Comet ISON comes into view in new NASA image, could prove to be largest comet ever seen

If you are anything closely related to a science geek, space nerd, casual star gazer or hard core astronomer, you have most likely heard of Comet ISON. NASA has just released awesome video of the comet streaking through space. ISON could prove to be the largest comet the Earth has seen in recorded history later this fall.

 

 

Later this year, Comet ISON will make a close pass to Earth and as it approaches the sun, its tail will glow as well as grow. Many leading authorities believe that ISON will be the largest comet ever witnessed from Earth's surface. At its peak it could be brighter than the full moon, and its tail could stretch the width of 96 full moons.

 

Chances are high that ISON might even be bright enough to be visible during the daytime, which is virtually unheard of. I for one have set aside several days in November and December to photograph and observe the great comet, which is believed to have originated in the Oort Cloud and has an orbit of several hundred thousand years.
