to the dawn of the space age with Mercury, Gemini, Apollo and space shuttle missions.While technology drove much of the suit design to maintain an airtight barrier to the vacuum of space and to protect from solar radiation, fashion aesthetics of the time also played a role, Lewis said. The original Mercury seven astronaut suits were unique from all others with a silvery coating to introduce America's space explorers to the world."NASA had a demand to create the astronauts into a whole new corps, a non-military corps. So here was an opportunity to dress them in a new uniform ... that evokes sensibilities of that Buck Rogers imagination," she said. "All of these guys, the engineers, they grew up on science fiction. They fed it with their ideas, and they were consumers of it at the same time."Curators are working to find ways to preserve spacesuits because some materials are decomposing, discoloring or becoming rigid some 50 years after they were created.The spacesuit show is traveling to 10 cities, moving next to Tampa, Fla., Philadelphia and Seattle through 2015.VIDEO: Russian Rocket Explodes on Live TVTwo companion exhibits at the National Air and Space Museum also highlight 50 artworks of about 550 new items added to the Smithsonian's growing space art collection over the past decade. They include portraits of astronomer Carl Sagan and astrophysicist Neal deGrasse Tyson, and a photograph of first female shuttle commander Eileen Collins
useum, after announcing the discovery.Wooly mammoths are thought to have died out around 10,000 years ago, although scientists think small groups of them lived longer in Alaska and on Russia's Wrangel Island off the Siberian coast.A growing chorus of scientists have been targeting the mammoth for so called de-extinction in recent years, at the same time that others argue against tampering with Mother Natures plans. Bringing back a dead species raises a host of issues, wrote two ethicists recently.RELATED: Boy in Alaska Finds Mammoth Tooth"The critical ethical issue in re-creating extinct species, or in creating new kinds of animals, is to first determine through careful scientific study what is in their interests and to ensure that they live good lives in the world in which they are create," wrote Julian Savulescu, who studies ethics at Monash University, and Russell Powell, a philosophy professor at Boston University."If we are confident that a cognitively sophisticated organism, such as a mammoth, would lead a good life, this may provide moral reasons to create it whether or not that animal is a clone of a member of an extinct lineage." 17 animals scientists want to bring back from extinction Giant Ice-Age Mammals Brought to Life
