'Picture perfect' Atlas V launch sends four NASA satellites into orbit

The Atlas V rocket lifts off from Space Launch Complex 41 at Cape Canaveral Air Force Station carrying four Magnetospheric Multiscale, or MMS, spacecraft on a mission to study magnetic reconnection. Scientists believe MMS will provide insights into the fundamental process that occurs throughout the universe. Liftoff was at 10:44 p.m. EDT.

Cape Canaveral, Fla. An umanned rocket lit up the night sky over Florida like a larger-than-life roman candle Thursday night (March 12), carrying a four satellites on a mission to seek an explosive phenomenon in Earth's magnetic field.

The United Launch Alliance Atlas V rocket blasted off from a launch pad here at Cape Canaveral Air Force Station at 10:44 p.m. (0244 p.m. GMT March 13), sending NASA's fourMagnetospheric Multiscale satellites(MMS) on their way to hunt for magnetic reconnection events in Earth's magnetic field. NASA capturedspectacular video of the nighttime MMS satellite launch.

NASA launch manager Omar Baez said it was a "picture perfect" launch for the Atlas V and the four MMS satellites. "Everybody is cheering and it appears that all four are where they need to be," Baez said after the launch. [See more launch photos for NASA's Magnetospheric Multiscale Mission]

Roughly 3,850 people were expected to watch the launch from the Kennedy Space Center campus and the Banana Creek, NASA Causeway as the Atlas V streaked into the clear, windy night sky over Florida.

The Atlas V was carrying four satellites that comprise the Magnetospheric Multiscale mission, or MMS, which will orbit together through the Earth's magnetic field. The$1.1 billion MMS missionwill study a phenomenon known as magnetic reconnection, the key driver of what is known as space weather, which includes solar flares and coronal mass ejections, as well as geomagnetic storms and the auroras at the north and south poles. These events can damage human-made satellites and create electric surges in power grids on the ground.

John Durelli, an MMS scientist at the NASA Goddard Space Flight Center, said "the whole MMS team" came to Florida to watch the launch, many of them with their families. When asked how he was feeling about the launch, Durelli said he and his colleagues were using the phrase, "euphora-terror."

"Some people have been [working on MMS] for 10 years, so it's been a long time in development," Durelli said. "You have this combined feeling: you can't believe it's finally happening, but also, 'Oh my god! What if something goes wrong!'"

MMS is the only space experiment dedicated solely to studying magnetic reconnection. This process occurs when magnetic field lines break and reconnect in the presence of plasma. The magnetic fields release huge amounts of energy that canaccelerate the plasma to nearly the speed of light. The four MMS satellites were built and tested at NASA's Goddard Space Flight Center in Greenbelt, Maryland. Multiple institutions and universities contributed to the science and instrumentation on the MMS satellites.

It is not yet known how the energy from magnetic field lines is transformed into heat and kinetic energy during magnetic reconnection, the mission scientists say. The four MMS satellites willfly in a pyramid shape, which will allow them to take data on magnetic reconnection events in three dimensions. The satellites will observe these extreme events all the way down to the level of electrons a resolution 100 times higher than previous experiments that have observed this phenomenon, according to MMS scientists.

Sen. Ted Cruz pleads with NASA to stop focusing on Earth

WASHINGTON, March 14 (UPI) -- During a hearing where NASA's $18.5 billion budget request was considered, Sen. Ted Cruz, R-Texas, questioned NASA's objectives.

"I'd like to start by asking a general question," Cruz said to NASA Administrator Charles Bolden. "In your judgment, what is the core mission of NASA?"

"Our core mission from the very beginning has been to investigate, explore space and the Earth environment, and to help us make this place a better place," Bolden said, referencing the National Aeronautics and Space Act of 1958 that created NASA.

Cruz disagreed, saying Americans believe NASA is strictly for exploring space. "I am concerned that NASA in the current environment has lost its full focus on that core mission," Cruz said.

Cruz's concerns seemed to express his opinion that NASA's focus on climate change was unnecessary and wasteful. Bolden defended the agency's focus on the Earth, saying, "We can't go anywhere if the Kennedy Space Center goes underwater and we don't know it -- and that's understanding our environment." He also said he's very proud of NASA's Earth-science program.

Cruz was made chair of the Senate subcommittee on Space, Science, and Competitiveness, which oversees NASA, in January.

Darbha grass, a natural preservative

Traditional tropical grass, Darbha, has been identified as an eco-friendly food preservative.

This finding was evolved in a research study undertaken jointly by the Centre for Nanotechnology and Advanced Biomaterials (CeNTAB) and the Centre for Advanced Research in Indian System of Medicine (CARISM) of the SASTRA University, Thanjavur, under the supervision of Dr. P. Meera and Dr. P. Brindha respectively.

Darbha (Desmotachya bipinnata) is a tropical grass considered a sacred material in Vedic scriptures and is said to purify the offerings during such rituals.

At the time of eclipse, people place that grass in food items that could ferment and once the eclipse ends the grass is removed.

A systematic research was conducted by the SASTRA University researchers, in which cows curd was chosen as a food item that could ferment easily.

Five other tropical grass species, including lemon grass, Bermuda grass, and bamboo were chosen for comparison based on different levels of antibiotic properties and hydro phobicity.

Electron microscopy of different grasses revealed stunning nano-patterns and hierarchical nano or micro structures in darbha grass while they were absent in other grasses.

On studying the effect of various grasses on the microbial community of the curd, darbha grass alone was found to attract enormous number of bacteria into the hierarchical surface features.

These are the bacteria responsible for fermentation of cows curd.

During eclipse, the wavelength and intensity of light radiations available on the earths surface is altered. Especially, the blue and ultraviolet radiations, which are known for their natural disinfecting property, are not available in sufficient quantities during eclipse.

You don't like to think about it, but between the up-front cost and the monthly contract payments, yourphone costs you a fair bit of money. What you might not realize is that it can make you money, too.

You wont get rich, but you can pay for a few trips to Starbucks. Heres how to get started.

1. Sell your photos

I've talked in the past about making money with microstock photography, but it involves taking pictures, moving them to a computer, cleaning them up, finding a good site to upload them and then promoting them. It would be nice if you could trim down the process.

Foapis an app (Android, Apple; Free) that does just that. Simply take pictures with your smartphone's camera and your favorite photo app, and then add them to Foap.

Just about any kind of image can sell if a company thinks it will work for it. That means that cute pet picture, vacation photos, even photos of food if you have those.

There are no limits on how many photos you can upload, and for every sale you get $5.If you want to make more, Foap offers photo missions where big brands pay hundreds or thousands to get specific photos.

2. Do tiny tasks forbig payoffs

If you don't mind getting out and about, you can take small jobs around your city. These are things like verifying that a display stand has been put up in a store, or the arrangements of productson a shelf.If you don't like to travel, some tasks can even be done from your living room.

Awesome tech you cant buy yet: Waterproof drones, robotic pancake printers

At any given moment there are approximately a zillion different crowdfunding campaigns happening on the Web. Take a stroll through Kickstarter or Indiegogo and youll find theres no shortage of weird, useless, and downright stupid projects out there alongside some real gems. Weve cut through the Pebble clones and janky iPhone cases to round up the most unusual, ambitious, and exciting projects out there this week. Keep in mind that any crowdfunded project even the best intentioned can fail, so do your homework before cutting a check for the gadget of your dreams.

Remember that nifty Bluetooth-enabled padlock that popped up on Kickstarter a few months back the Noke? Well Fuz Labs, the startup that made the device, is now back on the crowdfunding scene in hopes of funding its latest creation: a Bluetooth U-lock for your bike. Aesthetically, the new lock looks almost exactly like the old-school U-lock you know and love just without any keyholes or combination dials. Instead, it uses its Bluetooth brains to communicate with your smartphone and detect when youre close by. To open it, just click the lock shaft once and itll automatically look for a phone with a compatible Bluetooth key, and then unlock when it finds one. You dont even need to take your phone out of your pocket.For the most part, it retains the originals features, but Fuz Labs has also introduced a few new features in the new lock. The U-Lock also sports an integrated alarm system designed to scare off would-be thieves, and GPS tracking to help you remember where you locked your wheels up.

Flying a drone over solid ground is one thing, but flying it over water is a whole nother ball game. With all manner of electronics on board, an unexpected aquatic landing is almost always a death sentence for your drone, which makes flying it much more stressful. Thats not the case for the Splash Drone, however. Recently launched on Kickstarter, this hardy little quadcopter is encased in a buoyant waterproof shell, so it can safely land and float on water without being damaged. But waterproof components arent the only trick Splash has up its sleeve. Even without the watertight hull, its still got an impressive list of features. On its underbelly, the Splash is outfitted with a gimbal, allowing you to mount a GoPro on it and shoot super-stable video. This gimbal is also completely waterproof, so you can shoot while either airborne or submerged, and its also got anauto-follow function, so it can shoot video autonomously while you play in the water.

Do you burn through notebooks and find yourself constantly having to buy new ones? Rocketbook might be just what you need.Freshly launched on Indiegogo, the notebook is designed to be completely reusable paper and all. Once you fill up all the pages, the Rocketbook is able to digitize all your notes and store them in the cloud, and then clear all the pages so you can write on them again. The pages of the notebook (which are just regular-ol paper, by the way) feature a set of seven different symbols, which can be mapped to different cloud storage services. Mark one of the symbols on the page, and when you scan it with Rocketbooks accompanying smartphone app, a digitized copy of the page will instantly be sent to the cloud storage platform of your choice.After youve scanned, digitized, and saved your notes, you can just pop Rocketbook in the microwave for 30 seconds and itll erase all your notes so long as you use a Pilot FriXion pen.

Its been nearly a year since we last heard anything about PancakeBot, but now the creator is back with a new-and-improved version thats ready for mass production. PancakeBot 2.0 boasts a number of big improvements over the original, the most notable of which is definitely the accompanying software application. To make your own pancake design, you can now either freehand it, or upload an image and trace over the lines. Either way, the program will track every line you make with your mouse and then recreate the design with pancake batter on the skillet. In other words, you dont need to have crazy CAD skills to design a cool pancake. The batter extruder has also been updated and now features onboard controls that allow you to adjust how quickly batter gets squirted onto the skillet. This is a pretty big deal, as it allows you to adjust PancakeBot so that it can handle batters of varying viscosity. Without these controls, youd basically have to make batter exactly the same way every time you make breakfast.

Additive manufacturing (aka 3D printing) gets all the attention these days, but despite the feverish pace at which the technology is advancing, traditional manufacturing processes still carry certain advantages namely, the ability to work with materials other than plastic. Theyre coming along, but 3D printers that print anything other than PLA or ABS are ridiculously expensive, so if you want to make something out of metal or wood, your best bet is to go with a traditional CNC mill. The only downside, however, is that mills generally cant make many of the exotic impossible shapes that 3D printers can. Wouldnt it be nice if there was a machine that could give you best of both worlds? Enter: the BoXZY Rapid Change FabLab. It can do it all printing in plastic, milling wood or metal, and even laser cutting/engraving. Each tool exists as a rapid-change attachment, so you can swap from mill, to 3D printer, to laser cutter in a matter of seconds.
