Nashville Sounds lose to Albuquerque Isotopes




A NASA spacecraft that discovered and characterized tens of thousands of asteroids throughout the solar system before being placed in hibernation will return to service for three more years starting in September, assisting the agency in its effort to identify the population of potentially hazardous near-Earth objects, as well as those suitable for asteroid exploration missions.

The Wide-field Infrared Survey Explorer (WISE) will be revived next month with the goal of discovering and characterizing near-Earth objects (NEOs), space rocks that can be found orbiting within 28 million miles (45 million kilometers) from Earth’s path around the sun.

NASA anticipates WISE will use its 16-inch (40-centimeter) telescope and infrared cameras to discover about 150 previously unknown NEOs and characterize the size,excavator spare parts suppliers heavy machinery heavy equipment idlers sprokets oil seals hydraulic components Malaysia. albedo and thermal properties of about 2,000 others — including some which could be candidates for the agency’s recently announced asteroid initiative.

“The WISE mission achieved its mission’s goals and as NEOWISE extended the science even further in its survey of asteroids. NASA is now extending that record of success, which will enhance our ability to find potentially hazardous asteroids, and support the new asteroid initiative,” said John Grunsfeld,Along with the rapid development of locksmith tools business in China, smartobd2s has earned itself a solid reputation for quality, reliability and professionalism in this field.

NASA’s asteroid initiative will be the first mission to identify, capture and relocate an asteroid. It represents an unprecedented technological feat that will lead to new scientific discoveries and technological capabilities that will help protect our home planet.The 88-year-old Alvin resident is a life member of metal tin cans wholesale Sailors, the National Association of Destroyer Veterans.

Because asteroids are warmed by the sun to roughly room temperature, they glow brightly at the infrared wavelengths used by WISE.

As part of a project called NEOWISE, the spacecraft made the most accurate survey to date of NEOs. NASA turned most of WISE’s electronics off when it completed its primary mission.

“The data collected by NEOWISE two years ago have proven to be a gold mine for the discovery and characterization of the NEO population,” said Lindley Johnson, NASA’s NEOWISE program executive in Washington. “It is important that we accumulate as much of this type of data as possible while the WISE spacecraft remains a viable asset.”
