WATCH ASTRONAUTS SLEEP
NASA has started beaming live video from just outside the International Space Station, but there’s a catch: The online feeds are available only when the station’s crew is asleep or off duty.
That’s because NASA has only four communications links for sending data to Earth and wants to have all of them free for day-to-day operations while the crew is awake and working, agency spokesman Kelly Humphries said.
NASA also opted not to show video from inside the cramped space station to give astronauts privacy. “It would be like Big Brother looking over your shoulder 24/7,” he said.
When the crew is asleep and the Web streaming is going on, remote cameras will show Earth or other parts of the sky as seen from the space station, or parts of the station’s exterior as it orbits 225 miles above Earth.
A&T’S FLEET GOING GREEN
AT&T Inc. said it will spend up to $350 million over five years to buy more than 8,000 Ford Motor Co. vans and trucks, then convert them to run on compressed natural gas.
It is the largest commitment by a U.S. corporation to vehicles using alternative fuels, the phone company said.
Natural gas is a fossil fuel, but burning it produces 25 percent less carbon emissions than using gasoline, AT&T said. Compared with oil, the U.S. produces a greater proportion of the natural gas it uses.
