26.06.10- Pan-STARRS on Patrol.

You can rest a little easier tonight; astronomers now have a new and powerful tool in the hunt for killer space rocks. The Panoramic Survey Telescope & Rapid Response System or Pan-STARRS went online recently May 13th. Placed atop Haleakala, Pan-STARRS was constructed by engineers and astronomers at the University of Hawaii and is now owned and operated by a group of 10 institutions known collectively as the PS1 Science Consortium. The mission of Pan-STARRS is simple and straight forward; to survey the entire night sky and use sophisticated search algorithms to see if anything has moved from night to night. By rejecting known or identified objects, Pan-STARRS can go after objects of particular concern; Near Earth Objects (NEO’s) sometimes also termed Potentially Hazardous Asteroids or PHA’s. To do this, Pan-STARRS is equipped with a 60” inch diameter telescope and the largest digital camera ever built, containing a total of 1,400 megapixels. This allows it to capture a wide field area 40 times as large as the Full Moon, and it will take 500 such exposures each night. Gigantic survey projects such as Pan-STARRS pose a major challenge for data transmission and storage; Pan-STARRS will generate 4 terabytes of data per night: this will all be analyzed and archived at Maui’s High Performing Computing Center. Pan-STARRS 1 is also a forerunner to an even more ambitious project known as Pan-STARRS 4 which will be four times as powerful. Not only will Pan-STARRS discover an expected 100,000 asteroids, but it will also catalog an estimated 1 billion stars and half as many galaxies. Expect the usual complement of comets bearing the Pan-STARRS name as generally happens during any automated deep sky survey, as well as a flood of imagery just awaiting amateur perusal… I’m gonna need a faster Internet connection yet again!
