On June 26, 1959, then-Langley-research Francis Rogallo examined the Rogallo wing in the 7x10 FT Tunnel. Originally conceived as a means of bringing manned spacecraft to controlled, soft landings, Rogallo's concept was avidly embraced by later generations of hang-gliding enthusiasts. -- Photograph published in Winds of Change, 75th Anniversary NASA publication (page 18), by James Schultz.

Team kite  This kite was part of the scientific tool kit. It carried a camera that can be used to make high-resolution mosaics of the study site. Credit: NASA/GSFC/Jacob Bleacher   In June, five student journalists from Stony Brook University  packed their hiking boots and hydration packs and joined a NASA-funded science team for 10 days on the lava fields of Kilauea, an active Hawaiian volcano. Kilauea’s lava fields are an ideal place to test equipment designed for use on Earth’s moon or Mars, because volcanic activity shaped so much of those terrains. The trip was part of an interdisciplinary program called RIS4E – short for Remote, In Situ, and Synchrotron Studies for Science and Exploration – which is designed to prepare for future exploration of the moon, near-Earth asteroids and the moons of Mars.

University Students Join NASA on Trip to Hawaiian Volcano
NASA's James Webb Space Telescope has a giant custom-built, kite-shaped sunshield driven by mechanics that will fold and unfold with a harmonious synchronicity 1 million miles from Earth.  Like a car, many mechanical pieces in the Webb telescope's sunshield will work together to open it from its stored folded position in the rocket that will carry it into space.  According to car manufacturers, a single car can have about 30,000 parts, counting every part down to the smallest screws. Like getting all of the parts in a car to operate together, the mechanical parts of the sunshield have to work in the same way.  The sunshield support structure contains well over 7,000 flight parts, including springs, bearings, pulleys, magnets, etc. In addition, the sunshield has hundreds of custom fabricated pieces. Most mechanical pieces were developed exclusively for the sunshield, with a few from existing designs.   Read more: <a href="http://go.nasa.gov/2cXcQMT" rel="nofollow">go.nasa.gov/2cXcQMT</a>
A Mechanical Harmony to NASA's Webb Telescope Sunshield
The Sunshield on NASA's James Webb Space Telescope is the largest part of the observatory—five layers of thin membrane that must unfurl reliably in space to precise tolerances. Last week, for the first time, engineers stacked and unfurled a full-sized test unit of the Sunshield and it worked perfectly.  The Sunshield is about the length of a tennis court, and will be folded up like an umbrella around the Webb telescope’s mirrors and instruments during launch. Once it reaches its orbit, the Webb telescope will receive a command from Earth to unfold, and separate the Sunshield's five layers into their precisely stacked arrangement with its kite-like shape.  The Sunshield test unit was stacked and expanded at a cleanroom in the Northrop Grumman facility in Redondo Beach, California.  The Sunshield separates the observatory into a warm sun-facing side and a cold side where the sunshine is blocked from interfering with the sensitive infrared instruments. The infrared instruments need to be kept very cold (under 50 K or -370 degrees F) to operate.   The Sunshield protects these sensitive instruments with an effective sun protection factor or SPF of 1,000,000 (suntan lotion generally has an SPF of 8-50).  In addition to providing a cold environment, the Sunshield provides a thermally stable environment. This stability is essential to maintaining proper alignment of the primary mirror segments as the telescope changes its orientation to the sun.  The James Webb Space Telescope is the successor to NASA's Hubble Space Telescope. It will be the most powerful space telescope ever built. Webb is an international project led by NASA with its partners, the European Space Agency and the Canadian Space Agency.
