The Windows 7 driver store includes a small collection of drivers for legacy devices, mostly older printers, modems, scanners, infrared ports, PCMCIA controllers, and other oddball devices that don’t use Plug and Play connections. As you might suspect, Windows will not automatically set up such devices, and you’re rolling the dice if you find one of these old but still worthwhile devices and try to install an old driver.

But what if the device in question is valuable to you and can’t be easily replaced by a newer, supported one? Then by all means give it a try. Download the most recent hardware drivers you can find (ideally, for Windows XP or Windows Server 2003), and then use the Add Hardware wizard to complete the hardware setup process. Follow these steps:

1. If you’ve found a downloadable driver package or a CD that came with the device, look for a Setup program and run it. This option places the driver files on your hard disk and simplifies later installation steps.

2. Connect the new hardware to your computer. In the case of an internal device such as an add-in card, turn off the computer, add the device, and then restart.

3. Open Device Manager, select any item in the list of installed devices, and then click Add Legacy Hardware on the Action menu.

4. Click Next to skip past the Welcome screen. On the next wizard screen, choose how you want to select the device to be installed.

• For printers, network cards, modems, and other devices that can be detected mechanically, choose Search For And Install The Hardware Automatically (Recommended). After you click Next, the wizard quickly runs a detection module that searches for anything on its list of non–Plug and Play devices. If it finds the new device, it installs the driver automatically, and your work is finished. If the wizard doesn’t find any new hardware, you’ll be prompted to click Next and look manually.
• If you have a driver on a disc, skip the detection process. Choose Install The Hardware That I Manually Select From A List (Advanced) and click Next.

5. From the Common Hardware Types list, select a hardware category (or the inclusive Show All Devices category) and click Next.

6. From the master list of available drivers, select the device manufacturer and the correct model. Click Next to continue. Follow the prompts to complete the wizard.

Russia is considering sending a spacecraft to a large asteroid to knock it off its path and prevent a possible collision with Earth, the head of the country’s space agency said Wednesday.

Anatoly Perminov said the space agency will hold a meeting soon to assess a mission to Apophis, telling Golos Rossii radio that it would invite NASA, the European Space Agency, the Chinese space agency and others to join the project once it is finalized.

When the 270-meter (885-foot) asteroid was first discovered in 2004, astronomers estimated the chances of it smashing into Earth in its first flyby in 2029 were as high as 1-in-37, but have since lowered their estimate.

Further studies ruled out the possibility of an impact in 2029, when the asteroid is expected to come no closer than 18,300 miles (29,450 kilometers) above Earth’s surface, but they indicated a small possibility of a hit on subsequent encounters.

In October, NASA lowered the odds that Apophis could hit Earth in 2036 from a 1-in-45,000 as earlier thought to a 1-in-250,000 chance after researchers recalculated the asteroid’s path. It said another close encounter in 2068 will involve a 1-in-330,000 chance of impact.

Without mentioning NASA findings, Perminov said that he heard from a scientist that Apophis is getting closer and may hit the planet. “I don’t remember exactly, but it seems to me it could hit the Earth by 2032,” Perminov said.

“People’s lives are at stake. We should pay several hundred million dollars and build a system that would allow to prevent a collision, rather than sit and wait for it to happen and kill hundreds of thousands of people,” Perminov said.

Scientists have long theorized about asteroid deflection strategies. Some have proposed sending a probe to circle around a dangerous asteroid to gradually change its trajectory. Others suggested sending a spacecraft to collide with the asteroid and alter its momentum, or using nuclear weapons to hit it.

Perminov wouldn’t disclose any details of the project, saying they still need to be worked out. But he said the mission wouldn’t require any nuclear explosions.

Hollywood action films “Deep Impact” and “Armageddon,” have featured space missions scrambling to avoid catastrophic collisions. In both movies space crews use nuclear bombs in an attempt to prevent collisions.

“Calculations show that it’s possible to create a special purpose spacecraft within the time we have, which would help avoid the collision without destroying it (the asteroid) and without detonating any nuclear charges,” Perminov said. “The threat of collision can be averted.”

Boris Shustov, the director of the Institute of Astronomy under the Russian Academy of Sciences, hailed Perminov’s statement as a signal that officials had come to recognize the danger posed by asteroids.

“Apophis is just a symbolic example, there are many other dangerous objects we know little about,” he said, according to RIA Novosti news agency.

NASA’s Mars rover Spirit will mark six years of unprecedented science exploration and inspiration for the American public on Sunday. However, the upcoming Martian winter could end the roving career of the beloved, scrappy robot.

Spirit successfully landed on the Red Planet at 8:35 p.m. PST on Jan. 3, 2004, and its twin Opportunity arrived at 9:05 p.m. Jan. 24, 2004. The rovers began missions intended to last for three months but which have lasted six Earth years, or 3.2 Mars years. During this time, Spirit has found evidence of a steamy and violent environment on ancient Mars that was quite different from the wet and acidic past documented by Opportunity, which has been operating successfully as it explores halfway around the planet.

A sand trap and balky wheels are challenges to Spirit’s mobility that could prevent NASA’s rover team from using a key survival strategy for the rover. The team may not be able to position the robot’s solar panels to tilt toward the sun to collect power for heat to survive the severe Martian winter.

Nine months ago, Spirit’s wheels broke through a crusty surface layer into loose sand hidden underneath. Efforts to escape this sand trap barely have budged the rover. The rover’s inability to use all six wheels for driving has worsened the predicament. Spirit’s right-front wheel quit working in 2006, and its right-rear wheel stalled a month ago. Surprisingly, the right-front wheel resumed working, though intermittently. Drives with four or five operating wheels have produced little progress toward escaping the sand trap. The latest attempts resulted in the rover sinking deeper in the soil.

“The highest priority for this mission right now is to stay mobile, if that’s possible,” said Steve Squyres of Cornell University in Ithaca, N.Y. He is principal investigator for the rovers.

If mobility is not possible, the next priority is to improve the rover’s tilt, while Spirit is able to generate enough electricity to turn its wheels. Spirit is in the southern hemisphere of Mars, where it is autumn, and the amount of daily sunshine available for the solar-powered rover is declining. This could result in ceasing extraction activities as early as January, depending on the amount of remaining power. Spirit’s tilt, nearly five degrees toward the south, is unfavorable because the winter sun crosses low in the northern sky.

Unless the tilt can be improved or luck with winds affects the gradual buildup of dust on the solar panels, the amount of sunshine available will continue to decline until May 2010. During May, or perhaps earlier, Spirit may not have enough power to remain in operation.

“At the current rate of dust accumulation, solar arrays at zero tilt would provide barely enough energy to run the survival heaters through the Mars winter solstice,” said Jennifer Herman, a rover power engineer at NASA’s Jet Propulsion Laboratory in Pasadena, Calif.

The team is evaluating strategies for improving the tilt even if Spirit cannot escape the sand trap, such as trying to dig in deeper with the wheels on the north side. In February, NASA will assess Mars missions, including Spirit, for their potential science versus costs to determine how to distribute limited resources. Meanwhile, the team is planning additional research about what a stationary Spirit could accomplish as power wanes.

“Spirit could continue significant research right where it is,” said Ray Arvidson of Washington University in St. Louis, deputy principal investigator for the rovers. “We can study the interior of Mars, monitor the weather and continue examining the interesting deposits uncovered by Spirit’s wheels.”

A study of the planet’s interior would use radio transmissions to measure wobble of the planet’s axis of rotation, which is not feasible with a mobile rover. That experiment and others might provide more and different findings from a mission that has already far exceeded expectations.

“Long-term change in the spin direction could tell us about the diameter and density of the planet’s core,” said William Folkner of JPL. He has been developing plans for conducting this experiment with a future, stationary Mars lander. “Short-period changes could tell us whether the core is liquid or solid,” he said.

In 2004, Opportunity discovered the first mineralogical evidence that Mars had liquid water. The rover recently finished a two-year investigation of a half-mile wide crater called Victoria and now is headed toward Endeavor crater, which is approximately seven miles from Victoria and nearly 14 miles across. Since landing, Opportunity has driven more than 11 miles and returned more than 132,000 images.
