![]() On a previous spaceflight, he took a commemorative medallion that the group presented to the physicist Stephen Hawking. In microgravity odors quickly permeate the environment, and NASA found in a test that the smell of cream sherry triggered the gag reflex. Gravity can never be completely taken away, even if an astronaut is floating aimlessly in space, they will eventually come into the gravitational field of a large object. After returning to Earth, bone loss might not be completely corrected by rehabilitation however, their risk for fracture is not higher. Expedition 26 NASA Flight Engineer Cady Coleman discusses what daily life is like aboard an orbiting space laboratory on CBS' news program. ![]() Sellers, who was born in Crowborough but assumed dual UK-US nationality in 1991 to join Nasa, invited the society to send an item to go into space. NASA has learned that without Earth’s gravity affecting the human body, weight-bearing bones lose on average 1 to 1.5 of mineral density per month during spaceflight. Several sections stripped from the tree, which still stands at Woolsthorpe Manor, the physicist's former home in Lincolnshire, are stored in the society's vaults as part of a huge collection of Newton memorabilia donated by the antiquarian Sir Charles Turner in the 1700s. The society hopes to display the fragment at its 10-day festival of science and arts at the Southbank Centre, London, next month, and later at its HQ in Carlton House Terrace, London, where it will join exhibits including Newton's first telescope and his death mask. The stunt is part of the 350th anniversary celebrations of the Royal Society, of which Newton, who died in 1727, was a former president. The best way to avoid the effects of zero gravity is to create artificial gravity. Space is a vacuum and there is no gravity in a vacuum. The tree fragment, engraved with the scientist's name, is stowed aboard the shuttle Atlantis at Cape Canaveral, Florida, awaiting Friday's blast-off. There is no gravity in space and they do not weigh anything. "While it's up there, it will be experiencing no gravity, so if it had an apple on it, the apple wouldn't fall … Sir Isaac would have loved to see this, assuming he wasn't spacesick, as it would have proved his first law of motion to be correct." "I'll take it up and let it float around for a bit, which will confuse Isaac," said the 55-year-old Nasa astronaut, a veteran of two previous shuttle missions and a graduate of the University of Edinburgh.
