The right front wheel rover fault may be completely out of order

By Haven Frbiz

NASA a few days ago, said, "Opportunity" Mars probe failure of the right front, the question may finally have the complete failure of the right front to limit the "opportunities" for its scope of activity.

"Opportunity" is now the distance to stop a road crater, NASA's exploration mission group would like to see "opportunities" for its short-term through the rest, the right front to help solve the fault. It is learned that the "opportunities" for its right front wheel of the gearbox has been out of action, to its fall into the current predicament. The end of last year, "opportunities" in struggling to climb out from the Victoria crater, after he encountered such a problem. At that time, the "opportunities" for its left front wheel problem similar to their choice to leave the Victoria crater. NASA had worried that if the left front wheel completely out of order, "Opportunity" will never get trapped in the pit.

However, in last year's failure, the right front wheel did not malfunction. "Opportunity" mission team also successfully repaired gear failure - by the motor and transmission components for the rotating wheel. First, they allow the "Opportunity" for a few days rest, and then make it back, it seems that the redeployment of the operation of the gearbox lubricant. Hope to detect a similar task force to operate the "opportunity" to restore its vitality, but this failure may be "opportunities" for its first functional signs of decline.

Since 5 years ago since the landing of the Red Planet, "Opportunity" has 15 kilometers of road. "Opportunities" for its exploration project person in charge, the U.S. space agency's Jet Propulsion Laboratory约翰卡拉斯(John Callas) said: "As the transmission device may well be more bad things, so, even if the adoption of these measures may also beyond repair 'opportunity' No. fault. 'opportunity' No. There is always the risk of functional decline is inevitable. "

However, even if the right front wheel finally stopped running, "Opportunity" can still continue to explore Mars. "Opportunities" for its twin probe "Spirit" in the right front wheel failure in 2006, but ground-based mission control center operators through "Spirit" back-driven, so that it continues to roam the red planet. Callas said, "Opportunity" and "courage" is not accessible when the back drive very far goal.

It is learned that the "opportunities" for its forward drive, you can shoot pictures of the road in front of the complicated to the surface, ground mission control center can be the basis of these observational data to develop road route in advance. Finish the road in the route book, the "Opportunity" can see the path according to their activity until they receive a ground-based mission control center to send up-to-date route information. Once the "opportunities" for its moving backward, low-gain antenna will hinder the road in front of the line of sight. This means that the "opportunity" can not use its "Vision" activity, once the route is scheduled to finish, only to stop the road.

NASA has been in the United States March 7 to the "Opportunity" is sent back an order-driven, but did not play a role in the directive. Detection of the mission team is currently investigating the cause of the malfunction. In their view, this failure may be due to pre-set command and good driver conflict caused by the new directive, the new directive designed to allow the "opportunity" to remember its location, the next day wake up automatically according to the original route of the road. NASA engineers in the United States conduct a study on the fault at the same time, "Opportunity" is a temporary suspension in place, the study of rock above the ground.

Callas said that even though the right front wheel failure, but he is still the first to see "opportunities" for its Endeavor crater back to the edge of the photo excited. Endeavor crater is "opportunity" is important to detect the next goal. Callas said: "This feeling is as if sailors on the first sight of land. See it from more and more near us, of course, thrilled."

Endeavor crater is now away from "Opportunity" is around 12 kilometers away, but in order to avoid obstacles, "Opportunity" at least 16 kilometers of the road necessary to reach the destination, the trip is estimated to spend about two years. "Opportunity" mission team members to detect admit, parts and components are aging, "Opportunity" may never be the new goal can not arrive. - 18780

Gartner analyst Richard - Gordon (Richard Gordon) pointed out that the decline will hit the highest record over the past decade.

Gordon said: "The use of IT around the world businesses are required to budget cuts, and consumers are reducing non-essential expenditure. Businesses and consumers to respond to the adverse economic environment, the speed and extent are similar, which would cause 09 decline in IT spending over 01 years of 2.1%, although at that time coincided with the Internet bubble burst. "

Gartner pointed out that almost no field of science and technology to avoid the impact of IT spending downturn. Gartner expects this year's computer hardware spending will be reduced 15 percent, to 324.3 billion U.S. dollars; telecom spending will decline 3% to 1.89 trillion U.S. dollars; IT services spending will decline nearly 2 percent, to 796 billion U.S. dollars.
