Experiment of participating vehicles (IRVE)
Successfully protected its payload as it fell from a height of over 200 km to Earth. The inflatable heat shield was successfully tested on Monday, the first proof of the light, and during the spacecraft\'s passage through the planet\'s atmosphere, flexible devices can be used to protect the spacecraft.
Other spacecraft use solid thermal shields that either fall off as the spacecraft approaches the surface like the Mars rover, or gradually erode in the atmosphere.
But these sturdy shields are heavy and their weight limits the quality of the craft they are designed to protect because both have to be launched on the same rocket.
Their physical dimensions are also limited as their shields must be small enough to fit inside the launch rocket. Balloon-
Just as shields can theoretically avoid these problems, because they are light in weight and can expand to a relatively large size after folding up during launch.
These savings in weight and size make the payload of the spacecraft heavier.
The new shield is called inflatable.
Experiment of participating vehicles (IRVE)
On Monday morning, NASA launched a small rocket at the volops Flight Facility on the island of volops, Virginia.
This is the first successful test of the inflatable heat shield.

Beth Wusk, NASA\'s Langley Research Center in Hampton, Virginia.
The launch rocket fired 218 kilometers in about 4 minutes and then from 40-Kg shield
The shield is packed into 40-centimetre-
A wide body cloth when it takes off, but it expands on mushrooms.
Shape pillows that span 3 m when filled with pressurized nitrogen.
After separation from the rocket, IRVE and its payload, including navigation and data
Collect electronic equipment and return to the Earth\'s atmosphere at an extremely high speed.
Engineers expect it to reach Mach 5, about Mach 1.
7 kilometers per second, although they are unable to determine their actual speed until they complete the data analysis.
While Wusk estimates its temperature to exceed 140 degrees Celsius, it is also uncertain how hot it is when it splashes in the Atlantic Ocean.
The shield is hot by several layers-
Wear-resistant fabric woven from fine ceramic.
This includes the inner bag of silicon-
Coated kaifula fiber with balloonslike shape.
This design is similar to a device called \"ballute\", the intersection between the balloon and the parachute.
Like IRVE, the Ballutes sport inflatable bag, but not its flexible outer layer.
For years, some companies and government agencies have been working on ballute and other inflatable shield designs, including Andrews Space, based in Seattle, Washington.
\"NASA\'s test is very important because it is the most advanced inflatable heat shield test so far.
Jason Andrews, president of Andrews Space, said: \"application for entry.
Robert dirman, Lanley\'s chief engineer, said the temperature the shield can withstand depends on how wide it is.
A wider shield will slow the spacecraft down more and spread heat on a larger surface area.
\"It\'s like if you\'re swinging-
Ping pong racket through the edge of the air-
\"Then you turn it aside,\" he told the New Scientist . \".
\"This is spreading your energy to more areas.
The whole project, ping-
Table tennis or inflatable, are exposed to the air.
\"Since inflatable shields can be wider than rockets used to launch them, they can support more weight than conventional thermal shields.
The spacecraft itself is of low mass and therefore can carry more or heavier payload.
\"Now, the rigid ones have reached the limit of weight we are trying to send to Mars,\" dirman said . \".
\"If you want to bring a larger payload to Mars, they either do something very creative or switch to the inflatable device.
Dillman says IRVE can be used for missions on Mars or Titan, and can also bring things back to Earth from the International Space Station.
\"It can work in any place with an atmosphere,\" he said . \".
But to achieve that, IRVE will have to face more heat.
\"It\'s just a demo flight-it doesn\'t have all the heat that hits the atmosphere at interstellar speed,\" dirman said . \".
\"We need to do more development to test the larger version and expand to the payload that you can actually use on Mars.
Neil schetwood, Lanley\'s lead researcher, said: \"The team hopes to put the shield at a higher temperature in the next flight test in early 2012-which will take place from a higher height
