Scientists are keeping a close eye on orbital debris created when two communications satellites — one American, the other Russian — smashed into each other hundreds of miles above the Earth.

NASA said it will take weeks to determine the full magnitude of the unprecedented crash and whether any other satellites or even the Hubble Space Telescope are threatened.

The collision, which occurred nearly 500 miles over Siberia on Tuesday, was the first high-speed impact between two intact spacecraft, NASA officials said.

“We knew this was going to happen eventually,” said Mark Matney, an orbital debris scientist at Johnson Space Center in Houston.

NASA believes any risk to the international space station and its three astronauts is low. It orbits about 270 miles below the collision course.

Cutting the Unemployment Line

Even in this economic chaos, some jobs remain recession resistant

There are three options government can pursue when the economy goes south. First, the Fed can cut interest rates, buy up assets, and extend credit, all of which the central bank has already done. Second, Congress can cut taxes on businesses and consumers in the hope they will spend more. The first effort—last year’s tax rebates—didn’t have the intended effect since consumers used much of the windfall to pay down debt or save. The substantial tax cuts that will be part of the Obama stimulus package would likely have a similarly muted effect. Businesses and consumers, facing a tough credit environment and needing to repair their balance sheets, will likely use proceeds from the tax cuts to tide themselves over. The third option is for the government to directly purchase goods and services, to substitute the demand that consumers and businesses aren’t providing.

The Washington remnant of the Republican Party—40 senators and 178 representatives—is all for Options 1 and 2, cheap money and tax cuts. But they’re having great difficulty with Option 3. They have forgotten Richard Nixon’s famous line that “we’re all Keynesians now.” To them, spending government funds to goose the economy is unacceptable, not just because of the possibility of poor execution —i.e., pork. No, many are rejecting it as a matter of principle. Even though several Republican governors are pleading for assistance in the form of federal spending, Washington Republicans are saying no.

Newly elected Republican National Committee Chairman Michael Steele laid down the party line on CNN: “Let’s get this notion out of our heads that the government create jobs. Not in the history of mankind has the government ever created a job.” Sen. Jim DeMint of South Carolina succinctly summed up his opposition: “We can’t keep spending and borrowing to get us out of a recession.” Sen. Kit Bond of Missouri concedes that some government spending—such as spending on highways—can create jobs but thinks that spending on mass transit or alternative-transit infrastructure isn’t stimulative.  Read More…

SAN FRANCISCO – With an upgrade to its mobile maps, Google Inc. hopes to prove it can track people on the go as effectively as it searches for information on the Internet.

The new software to be released Wednesday will enable people with mobile phones and other wireless devices to automatically share their whereabouts with family and friends.

The feature, dubbed “Latitude,” expands upon a tool introduced in 2007 to allow mobile phone users to check their own location on a Google map with the press of a button.

“This adds a social flavor to Google maps and makes it more fun,” said Steve Lee, a Google product manager.

It could also raise privacy concerns, but Google is doing its best to avoid a backlash by requiring each user to manually turn on the tracking software and making it easy to turn off or limit access to the service.

Google also is promising not to retain any information about its users’ movements. Only the last location picked up by the tracking service will be stored on Google’s computers, Lee said.

The software plots a user’s location — marked by a personal picture on Google’s map — by relying on cell phone towers, global positioning systems or a Wi-Fi connection to deduce their location. The system can follow people’s travels in the United States and 26 other countries.
