Lightbulb NASA postpones flying saucer parachute test

NASA postpones flying saucer parachute test
Now I Wonder Where They Developed This Technology From???

Miami (AFP) - High waves forced NASA to postpone until Thursday the first test of the largest parachute ever deployed, during a flying saucer launch that will try out new technologies for landing on Mars.

If conditions improve, the test flight of the flying saucer, known as the Low-Density Supersonic Decelerator, will be broadcast live on NASA's website beginning at 1:30 pm (1730 GMT) on Thursday.

"The ocean wave height continues to be an issue for the crew that would recover the vehicle and its data after splashdown," NASA said after the postponement of Wednesday's planned attempt. A bid on Tuesday was also canceled because of ocean conditions.

The launch window for the test extends until June 12.

Since the atmosphere on Mars is so thin, any parachute that helps a heavy, fast-moving spacecraft touch down needs to be extra strong.

The US space agency figured out how to do this decades ago, beginning with the Viking mission that put two landers on Mars in 1976.

But with the goal of sending humans to Mars in the 2030s, the agency is now testing a more advanced, new generation of parachute technology, known as the Supersonic Ringsail Parachute, that could allow even heavier spacecraft -- the kind that may have humans and months of food and supplies on board -- to land softly.

"We want to see if the chute can successfully deploy and decelerate the test vehicle while it is in supersonic flight," NASA's Jet Propulsion Laboratory said in a statement.

The test vehicle weighs 6,808 pounds (3,088 kilograms), or about twice the weight of the kind of robotic rover spacecraft NASA is currently capable of landing safely on Mars.

The parachute, described by NASA's JPL as "the largest parachute ever deployed," is 100 feet (30 meters) in diameter.

The goal is for the chute to "slow the entry vehicle from Mach 2 to subsonic speeds," NASA said.

The test will involve sending the saucer, an inner-tube shaped decelerator and parachute to an altitude of 120,000 feet (37 kilometers) over the Pacific Ocean with the help of a giant balloon.

The balloon will release the spacecraft and rockets will lift the vehicle even higher, to 180,000 feet, reaching supersonic speeds.

"Traveling at three times the speed of sound, the saucer's decelerator will inflate, slowing the vehicle, and then a parachute will deploy at 2.35 times the speed of sound to carry it to the ocean’s surface," NASA said.

The first test flight of the flying saucer was in June 2014, and another test flight is planned in 2016.

A different kind of parachute known as the Supersonic Disksail was tested in the 2014 flight but it did not inflate as hoped, and shredded to pieces at the high speed and altitude.

NASA said researchers have since "gained significant insight into the fundamental physics of parachute inflation," and the team "has been re-writing the book on high speed parachute operations" since last year, the agency said.

I graduated from Eastern New Mexico University and lived 95 Miles SE from Roswell. While living in Loing in Lovington, N.M. a large Disc several hundred yards wide flew right down mainstreet in the afternoon on day and at the outskirts of town turned northwest toward the direction of Roswell. I was 19 years old at the time and you could see great the metallic details of the exterior of the craft.

I have a question about Roswell. How did the military officers of the first Nuclear Bomber Wing first be so incompetant as to release that they had a UFO and then that these same officers were not removed from their commands for being so incompetant and breakng chain of command?

I did not believe any of this either until events no longer allowed me that option. Always question things and accept nothing at face value! All of this is full of deception so be warned in advance!
