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.

The animation below shows the TGALS concept in action.

NASA tests TGALS glider-based satellite launch system

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.

NASA warns of 'megadroughts'

When it's finished, NASA's new rocket will be a beast. Taller than the Statue of Liberty, with the same amount of thrust as 13,400 locomotive engines and able to carry 154,000 pounds of payload, the same, as the space agency points out, as 12 elephants.

In an effort to show the progress of the new rocket, called the Space Launch System, NASA released a video showing crews building the rocket. And it also added a scene from a 2011 test of one of the three boosters giving an impressive display of its fire power at a Utah test range. Laying on its side, the rocket ignited with a concussive blast, then blasted a gush of fire out its tail at Mach 3, or three times the speed of sound. The great plume of smoke could be seen for miles.

Take a look:

NASA tests what it says are the most powerful solid rocket boosters ever built, which will be necessary for future missions to asteroids and to Mars on NASA's new rocket, the Space Launch System (SLS). (NASA's Marshall Center via YouTube)

Officials intend to use SLS to launch the new Orion space capsule on deep space missions, including to Mars. Orion recently went through an important test--flying on an unmanned 41/2-hour mission that sent a spacecraft designed for humans farther than any has gone in more than 40 years.

But while NASA heralds the SLS as the "world's most powerful rocket," it also has some powerful critics. Members of Congress have taken aim at the program, which is still in development and isnt expected to have its first test flight for another several years. (The recent Orion mission was aboard a Delta IV Heavy rocket built by the United Launch Alliance.)

After its first test flight in 2018 originally planned for 2017 but delayed because of funding issues SLS is then expected to perform its first manned flight in 2021.

But after that flight, future mission destinations remain uncertain, the GAO has said.

And at a recent Congressional hearing, Rep. Dana Rohrabacher (R-Calif.) said it could cost at least $10billion to develop this monstrous rocket project and called it a mistake.

Marco Caceres, a senior space analyst with the Teal Group, has also raised questions about the program.

There is no precedent in contemporary weather records for the kinds of droughts facing the country's West, if greenhouse gas emissions stay on course, a NASA study said.
