Moon Landing Hoax Evidence #1: Nasa Admits Can't Pass Through Van Allen Belt - Video
Recently, DARPA unveiled its ALASA system for launching satellites from fighter planes. Now NASA is upping the ante with its Towed Glider Air-Launch System (TGALS), which is designed to launch satellites from a twin-fuselage towed glider. Under development by NASA's Armstrong Flight Research Center at Edwards Air Force Base, California, it's designed as an economical method for putting spacecraft into low-Earth orbit with the first test flight of a scale prototype having already been conducted.
The aim of TGALS is the same as that of ALASA: to create a space launch system for small satellites that replaces the first stage booster rocket with a conventional aircraft. In its current form, ALASA uses a F-15 fighter jet, which provides a lot of speed, altitude, and vertical thrust. That's all well and good, but fighter jets are expensive to operate and there's a limit to what they can carry and where they can operate from.
TGALS' approach is to go for a more flexible and cheaper design by making an unmanned or pilot-optional glider that's cheaper to build than a custom aircraft, and uses an open structure for more flexibility in payload size. Because TGALS is towed into the air by a conventional aircraft and released at 40,000 ft (12,000 m), it can operate from even small municipal airports.
Once released by its tow plane, TGALS fires a solid or hybrid rocket booster that allows it to accelerate in a steep climb. If unmanned, it can potentially make steeper climbs with more g forces than even the F-15 because there's no pilot to consider. Once the craft reaches peak altitude, it drops the rocket stage, which fires and sends the satellite into orbit. Meanwhile, the glider returns to base.
According to NASA, TGALS' first test flight of a one-third-scale twin fuselage prototype was achieved on October 21 of last year. The 27-ft (8.2-m) wingspan craft was towed by the unmanned Dryden Remotely Operated Integrated Drone (DROID), and made two successful flights and landings on Rogers Dry Lake near Edwards Air Force Base.
The purpose of the flight was to test the double-hull design. This was doubly important because it was built with a combination of off-the-shelf parts and bespoke components, which presented a number of problems in matching the hulls with the bespoke center wing.
"One of the concerns was we didn't know what the outer wing sections were made of, how they were constructed, or what kind of loads they could take," says TGALS chief engineer Ryan Dibley. "We performed a loads test in NASA Armstrong's Flight Loads Lab where we cleared the structure up to 2 gs to ensure that the wings could handle the loads of the glider itself and then with a partial mass payload. In the near future, we will put a wing back in the loads lab and test it to the loads required to carry the full payload."
Now that the design has been found airworthy, NASA plans to equip it with a scale-model Mini Sprite rocket, built by Whittinghill Aerospace of Camarillo, California for launch scenario testing.

On April 30, 2013, NASA signed a contract with Russia's Federal Space Agency, Roscosmos, hiring the Russians to ferry U.S. astronauts to and from the International Space Station. The terms of this contract : six astronauts to be ferried, over four years, at a cost of $70.7 million a head.
That's more than SpaceX charges to send up to 4.85 metric tons of cargo into space. It's a lot to pay to send up one 180-pound astronaut.
$70.7 million?! NASAPilotTony Antonelli seems to think that a mite pricey.Photo: NASA .
But there's good news for NASA, and for taxpayers -- and for investors, too. NASA has had it up to here with paying exorbitant taxi fares to the Russians. And pretty soon, we'll be sending our astronauts back to space on our own rocket ships, for much cheaper.
To the Moon, Alice! (Or at least to the ISS.) Last month, NASA held a joint conference with its two contractors building a private commercial American "space taxi" service to the ISS -- Boeing and SpaceX . It's dubbed the Commercial Crew Transportation Capability project, or CCtCap , and NASA's plan is to pay Boeing $4.2 billion and SpaceX $2.6 billion to develop and operate a fleet of space taxis to shuttle astronauts to and from ISS.
Specifically, beginning in 2017:
If all goes well, NASA estimates that the cost of sending an astronaut to ISS in an American rocket ship will fall by 18% from what Roscosmos is charging -- to as low as $58 million. But one presumes that this is an average of the cost of the two companies' efforts. Given that Boeing is charging NASA 61% more to send astronauts to ISS in its CST-100 capsule than SpaceX bid for its Dragon V2 capsule, it's entirely possible that some "tickets" to ISS could be even cheaper than the $58 million average.
What it means to investors This is all great news for taxpayers. But what does it mean for investors? Well, I see three main takeaways:
So what's the real upshot here? As NASA administrator Charles Bolden explained it, getting a commercial space taxi service set up here in America means we won't "ever, ever [have] to write another check to Roscosmos."

Story highlights The current drought is bad, but it's no megadrought NASA: If greenhouse gas emissions don't drastically drop, the nation's West faces droughts that could last decades
No precedent even in the past 1,000 years.
The feared droughts would cover most of the western half of the United States -- the Central Plains and the Southwest.
Those regions have suffered severe drought in recent years. But it doesn't compare in the slightest to the 'megadroughts' likely to hit them before the century is over due to global warming.
These will be epochal, worthy of a chapter in Earth's natural history.
Even if emissions drop moderately, droughts in those regions will get much worse than they are now, NASA said.
The space agency's study conjures visions of the sun scorching cracked earth that is baked dry of moisture for feet below the surface, across vast landscapes, for decades. Great lake reservoirs could dwindle to ponds, leaving cities to ration water to residents who haven't fled east.
"Our projections for what we are seeing is that, with climate change, many of these types of droughts will likely last for 20, 30, even 40 years," said NASA climate scientist Ben Cook.
That's worse and longer than the historic Dust Bowl of the 1930s, when "black blizzards" -- towering, blustery dust walls -- buried Southern Plains homes, buggies and barns in dirt dunes.

Nano particles can be exploited for drug, DNA, and vaccine delivery in cells, diagnosis, and tissue engineering, Subbu S. Venkatraman of the Nanyang Technological University, Singapore, said at the international conference on Nanotoxicology.
He pointed out that being smaller, the nanoparticles could distribute and reach the specific target easily besides enhancing the effect of drugs. The Department of Chemistry and Biosciences of the Srinivasa Ramanujan Centre of the SASTRA University hosted the two-day conference that concluded on Saturday.
Mr. Venkatraman said that worldwide, so far 36 nanoproducts and 23 drug delivery products had been approved.
Dr. Kha Chen Yang James from the National University of Singapore spoke on exploiting non-specific adsorption of nanoparticles for biomedical applications wherein he explained the strategy of gold nano particle modification for their stability and effective delivery of nano drug. Gold nanoparticle could be coupled with other nanoparticles along with drug and that complex could be used effectively to treat cancer, he said.
During another session Dr. P. Gopinath of Indian Institute of Technology, Roorkee, spoke on the significant role of nanoparticles in managing various types of cancer. He described the least toxicity of nanoparticles that compared favourably with the existing drugs.
Dean Prof. K.G. Raghunathan, Head, Department of Chemistry and Biosciences, Dr. T. Jeyadoss, and convener of the conference Dr. S. Sudheer Khan spoke.
Over 100 research students and professors from various institutions presented research findings in the diverse field of nanotoxicology.

Kasetophono, friendly playlists for all kinds of music
By Emilios Harbis
As soon as you log on to kasetophono.com, the banner that comes up The soundtrack of your future memories is telling of the site's content and digital character.
Since going online in 2012, Kasetophono (Greek for cassette player) has been gaining new fans or listeners who bookmark the site's address with the kind of reverence usually attached to certain radio stations.
This is not a radio station, though, but a music platform developed and managed by a single individual, Andreas. The platform includes dozens of playlists, or what he refers to as tapes, all compiled according to a variety of themes. The website features a selection of playlists ranging from 20 to 30 songs, each exploring a theme such as a particular mood (joy, sadness), the weather (rain, sunshine) or a specific situation (from the ideal music to accompany a cooking session to lovemaking).
How did the idea for the website come about? Before I started Kasetophono what I had in mind was creating a blog and upload my playlists. The reason was simple, I wanted my friends to be able to listen to them. This is more or less how I started working on the first tapes about two-and-a-half years ago. Only 20 people listened in the first six months, but I didn't mind, because the actual process of developing online tapes was and still is fascinating, said Andreas. The website's variety of musical choices points to someone knowledgeable and with a broad interest in music.
"My relationship with music is somewhat peculiar. I remember one thing growing up: falling asleep with my earphones on. I always wanted to work on something related to music. I tried to become a DJ, a guitarist, a radio producer. I wanted to get into a sound engineering school. In the end I didn't manage to do any of the above and so I came up with the blog.
Meanwhile, the mood on Kasetophono is rather romantic. According to Andreas, the name itself evokes a certain element of nostalgia. Minimalist aesthetics coupled with tapes titled Vintage Wintertime or Whiskey in the Jar, among others, invite visitors to discover more and more playlists and music in general.
Each tape is a new challenge and compiled in a distinct way. Some take 10 minutes to make while others might take up to six months to put together. Some are based on their title while others have to do with the kind of emotion I want to bring evoke. In any case I'm after one thing: for even the most unseasoned of listeners to be able to enjoy each song without fast-forwarding to the next.
The website's creator does not keep the tape-recording process all to himself. Anyone wishing to compile and upload his or her own playlist along with a title and an image illustrating its theme are welcome to do so. So far, about 300 people have taken up the challenge and, according to Andreas, the nicest ones are the secret ones, those compiled and signed by young men as gifts to their girlfriends. What are his future plans for the website?

Dramatic dash-camera footage shows a school bus in Minnesota out of control after its driver had a medical emergency.
The video from Wednesday afternoon shows the bus with 11 school children on board swerve into a ditch and almost tip over.
Authorities in Aitkin County say the bus careened and weaved at speeds of 35 to 40 mph - at one point narrowly avoiding a head-on collision with another car.
At least one student on board called 911 to alert authorities to the driver's medical emergency.
To stop the bus, Minnesota state troopers blew out its tires.
"That's not something that any of us would expect when we hop on in any vehicle, let alone a school bus," said Aitkin County Sheriff Scott Turner.
No children inside the bus were injured.
Police say the driver may have suffered a possible diabetic reaction. He was treated at a local hospital and has since been released.
