Space Station crew can stay put despite debris
A piece of debris hurling through space no longer presents enough of a threat to force the International Space Station crew to move, NASA said late Tuesday.
"NASA flight controllers downgraded conjunction threat," the agency announced on its official Twitter feed. "No need to shelter in place required on space station."
Earlier, NASA had said the crew would shelter in place, meaning the three crew members would move into the Soyuz vehicle attached to the space station.
'Check out the world's lightest material'
It was a simple e-mail. But with just a few words, it capsulized the exact moment of an exciting scientific discovery.
"Check out the world's lightest material: 0.85 mg/cc!!" scientist Toby Schaedler wrote to his teammates at HRL Laboratories in Malibu, California. "It is holding up fine even after I squeezed it a little."
Six months later, HRL is announcing its discovery for the first time in a study published in November's Science magazine. When Light Years talked to physicist Bill Carter and project manager Leslie Momoda, the giddiness of inventing the lightest solid substance hadn't yet worn off. They were, well, practically floating on air.
