With the development of the technology, more and more new things are appeared in the market. For example space blankets. Also known as solar blankets, mylar blankets or emergency blankets, they help people stay warm. Everyone from mountaineers to astronauts to surgeons use them.
Even though space blankets are mass produced and cheaply available today, they had their start in the space program in the 1970s. In 1973, the Skylab space station began overheating while in orbit. Because of a broken heat shield, the temperature inside the station approached temperatures of 130 degrees Fahrenheit (54 degrees Celsius). As temperatures continued to rise, NASA personnel worried about the decay of equipment and food inside the station. The possibility of toxic gases was also a threat.
As they work to keep heat out, space blankets also work to keep heat in. Because they could reflect the wearer's body heat back toward the wearer, these blankets had potential for a multitude of uses. They/ve become invaluable to marathon runners to help stay warm at the end of a race. Hospitals find them useful to keep patients warm during surgery, as anesthesia tends to make people shiver. Campers, climbers and mountaineers -- anyone who may find themselves stranded in cold weather -- discover space blankets are an extremely lightweight and cheap addition to their first-aid kits. In 2005, after an earthquake devastated parts of Pakistan, charitable organizations delivered space blankets to the victims. People used them as both ground cover and warming blankets.
