NASA Spinoff

NASA Technology

When NASA researcher Stanford Hooker is in the field, he pays close attention to color. For Hooker, being in the field means being at sea. On one such research trip to the frigid waters of the Arctic, with a Coast Guard icebreaker looming nearby and the snow-crusted ice shelf a few feet away, Hooker leaned over the edge of his small boat and lowered a tethered device into the bright turquoise water—a new product devised by a NASA partner and enabled by a promising technology for oceanographers and atmospheric scientists alike.

Long-term human spaceflight means long-term menu planning. Since every pound of cargo comes with a steep price tag, NASA has long researched technologies and techniques to allow astronauts to grow their own food, both on the journey and in some cases at their destination. Sustainable food technologies designed for space have resulted in spinoffs that improve the nutrition, safety, and durability of food on Earth.

If you visit Glenn Research Center, you might encounter a photovoltaic (PV) array that looks unlike anything you’ve ever seen. In fact, what one would normally identify as the panel is actually a series of curved mirrors called solar concentrators, engineered to reflect sunlight rather than absorb it.

The next time you flip on a light switch, there’s a chance that you could be benefitting from data originally acquired during the Space Shuttle Program. An effort spearheaded by Jet Propulsion Laboratory (JPL) and the National Geospatial-Intelligence Agency (NGA) in 2000 put together the first near-global elevation map of the Earth ever assembled, which has found use in everything from 3D terrain maps to models that inform solar power production.

Hazy smog over cities and smoke pouring from the stacks of factories and power plants are visible reminders of the threat posed by air pollution to the environment and personal health. But air quality is often an unseen influence on our lives. Even on clear days, the air can be rife with particulate matter and other irritants that can trigger everything from minor allergies to life-threatening asthma attacks and other respiratory ailments. Indoors—where we spend as much as 90 percent of our time—pollutant levels can be 2–50 times higher than outdoors. The World Health Organization estimates that urban outdoor air pollution causes 1.3 million deaths worldwide per year, while in developing countries, indoor air pollution causes an estimated 2 million premature deaths.

“Right now, solar electric propulsion is being looked at very seriously,” says Michael Piszczor, chief of the photovoltaic and power technologies branch at Glen Research Center. The reason, he explains, originates with a unique NASA mission from the late 1990s.

NASA’s Stennis Space Center is located on 13,500 acres in Hancock County, Mississippi, surrounded by another 125,000 acres that act as a buffer for the deafening roar of rocket engines. It has witnessed the flame and smoke spout from the Saturn V rockets that would carry astronauts to the Moon for the first time, and the space shuttle main engines that would carry them into space more often than any other. More recently, it has hosted the testing of the J-2X engine belonging to the upper stage of NASA’s Space Launch System—technology that will power manned spaceflight during a new era of exploration beyond Earth’s orbit.

Originating Technology/NASA Contribution

In the course of time, circumstance, and coincidence, life sometimes completes some ironic and unlikely circles. During NASA’s early space exploration, a deceptively simple concept allowed scientists and engineers to manage thermal gain. They used highly reflective coated surfaces on ultra-light substrates to reflect infrared energy to effectively and reliably keep operating temperatures in the extremes of space at safe and manageable levels. That reflective insulation technology has kept thousands of satellites; all of NASA’s manned spacecraft, the Hubble Telescope, and most importantly, astronauts, safe and functional. NASA engineers used this technology to reflect infrared energy the way a child learns to redirect a sunbeam with a hand-held mirror.

altFast forward to 2009, when a young marine biologist working among the waterways of Florida’s East Coast, almost in the shadows of the iconic launch pad gantry sites at the Kennedy Space Center, employs that same NASA-developed principle that protects astronauts in space to manage the core temperature of one of nature’s most primitive and endangered creatures: the gentle manatee. The chain of events that brought marine biologist Artie Wong and his colleagues to the ideal solution started almost four decades ago, adjacent to these same waterways.

On May 14, 1973, Skylab launched into orbit and became a stunning example of what was possible for the Space Program. As the name implies, Skylab served as a space-based laboratory as well as an Earth-observing facility and a home base for three crews of astronauts. While Skylab proved that humans could live and work in outer space for extended periods of time, it also proved that great achievements often come with great challenges.

During launch, one of the protective shields on the outside of the spacecraft loosened, causing one solar panel to fall off, and preventing another from deploying. To plan for the spacecraft’s repair, Marshall Space Flight Center led a collaborative effort to start working around the clock.

Partnership

Over the next 10 days, NASA engineers called upon National Metalizing, of Cranbury, New Jersey, to help create a reflective parasol-type sunshield to deploy on Skylab in place of the protective shield. National Metalizing was a manufacturer of reflective material utilizing a radiant barrier technology originally developed for NASA in the 1950s. In the public domain for the last 30 years, the radiant barrier technology consists of a thin plastic material coated with vaporized aluminum to either deflect or conserve infrared energy.

Eleven days after Skylab launched, astronauts launched from a second spacecraft, visited, and deployed a parasol sunshade made with the radiant barrier technology. As for the maker of the material that saved the spacecraft, National Metalizing’s manufacturing capacity was used for industrial coating and lamination applications after the company was sold in the mid-1980s.

In 1980, a former director of sales and marketing for the company, David Deigan, founded a new company recently renamed Advanced Flexible Materials (AFM) Inc. Headquartered in Petaluma, California, the company employs the same reflective insulation technology to produce ultra-light, compact travel and stadium blankets; colorfully printed wraps to keep hundreds of thousands of marathon finishers safe from hypothermia each year; a successful line of Heatsheets outdoor products sold in retail stores around the world under the Adventure Medical Kits label; as well as reflective insulating lining fabrics for mittens, vests, and more. In 1996, the radiant barrier technology was inducted into the Space Foundation’s prestigious Space Technology Hall of Fame.


Product Outcome

Deigan began providing thin plastic blankets made with the radiant barrier technology to keep thousands of runners warm at the 1980 New York City Marathon. Depending on when and where a marathon takes place, temperatures can be cool, and when participants stop running, hypothermia can become a problem. Today, the Heatsheets for running events and triathlons are produced exclusively in an environmentally friendly, recyclable polyethylene form, and reflect up to 97 percent of a person’s radiant heat, providing an envelope of warm air around the body to prevent hypothermia.

altFor nearly two decades, Alice and Bill Wong volunteered at the New York City Marathon, helping to distribute thousands of Heatsheets at the finish line. In 2009, Alice contacted Deigan to see if his company would be willing to donate some of its heat-reflective products for an unusual cause. Her son, Artie, a marine biologist with a non profit club called Save the Manatee Club was searching for a solution to a unique challenge. The club’s members work with the State of Florida Fish and Wildlife Research Institute to track and document the migration routes of manatees through Florida’s waterways, some of them not far from the Kennedy launch pad gantries on Florida’s East Coast.

altAs a part of the tag-and-release program, the docile sea cows are lifted from the water, checked to record their vital signs, tagged, and then returned to the water. Because these sea mammals are unable to withstand temperatures below 60 °F without slipping into hypothermia, Artie was searching for a more effective way to cover the manatees and conserve their vital body heat. The NASA-derived technology that gave his parents a way to help warm up runners for so many years seemed like the ideal solution. AFM recommended a more suitable solution, and donated a composite material incorporating a soft, non-woven fabric laminated with an encapsulated reflective insulation layer that could withstand the corrosive effects of salt water and could be safely reused for extended periods of time.

The finished version of the product has warmed more than 2 million Japanese consumers as an ultra-light, compact blanket; a futon cover; and a travel blanket. Over the past decade, AFM has exported to Japan through its trading partner, D. Nagata Co. Limited.

From helping to save Skylab to helping to save the manatees, the NASA-derived technology is sure to continue making a difference in the future, both on Earth and in space.

Given the size of our planet and its wealth of resources, it is easy to forget that those resources are finite. As Earth’s human population continues to grow, the questions of how to effectively limit and recycle waste, avoid environmental contamination, and make the most of water and fuel reserves become all the more pressing.

Kennedy Space Center’s launch complexes have seen a lot. They have been the starting point for every manned NASA mission, from Mercury to Gemini, through Apollo, and are now seeing the space shuttle through its final launches. Kennedy, part of the Merritt Island Wildlife Refuge, is also home to over 1,500 different plant and animal species.
To help protect these living things, NASA works to keep the area as pristine as possible and that sometimes involves inventing new and innovative ways to clean up around the launch pads.
