Default Large Synoptic Survey Telescope

Cerro Pachón, a 2,682-metre mountain peak in northern Chile, has been selected as the site for the proposed Large Synoptic Survey Telescope (LSST), a Tucson-based project that will be able to scan the entire visible sky every three nights.
The world's most powerful survey telescope, the LSST will join the existing Cerro Tololo Inter-American Observatory, operated by the National Optical Astronomy Observatory, on Cerro Pachón.

The 8.4-meter telescope will be 50 times as powerful as any survey telescope, with the capability to image the entire visible sky in just days...

"The (LSST) will help us understand the development of dark matter over cosmic time and help us pin down the nature of dark energy" - Anthony Tyson.

The LSST ground-based telescope combines a wide field of view and an extremely sensitive digital camera—capable of producing 3,000 megapixel images—to provide scientists with a new way of looking at the universe. The LSST is expected to be ready for first light by 2012.

8.4 meters. Wow - for once a telescope has grown as the project matured. "Drinking from a fire hose" doesn't begin to describe the data challenges (or opportunities).

Nit: that webcam is for Gemini-N on Mauna Kea, a long way from Cerro Pachon. Here is the Gemini webcam for Cerro Pachon (and from the look of it, I wouldn't much want to be scheduled to observe tonight).

Hum,
tnx...
i just realised as i posted....
and the grid reference was just a guess...but it looks a good place to have telescopes...

Following some of the other Gemini site links, I see that the air can be really dry at other Chilean sites. For example, this page reports that the dew point at the Magellan site (Las Campanas, maybe 80 km north of Pachon and Tololo) is an impressive 1797.8 C.

Wow,
how do they stop the mirrors from melting?

BTW, i finally did manage to track down a correct location for Cerro Pachon

Latitude= 30 14 16.8, 30.238000 ; Longitude= 70 44 01.4, 70.733722

The Atacama plateau is the driest place on Earth.
These mountains are just perfect for the job.

It also features the Monturaqui meteor crater.

Hum,
according to Michael Caine, the driest place on Earth is the Lut Desert in eastern Iran.

Default Donors Bring Big Telescope a Step Closer

Published: January 5, 2008
A project to build a digital camera of cosmic dimensions on a mountaintop in Chile has received a $30 million boost from a pair of software moguls and philanthropists.

Charles Simonyi, formerly of Microsoft and now chief executive of Intentional Software, said Thursday that he would contribute $20 million to the project, known as the Large Synoptic Survey Telescope, or L.S.S.T. Bill Gates, founder of Microsoft, agreed to give $10 million.

When completed in 2014, the telescope — 330 inches in diameter and armed with a three-billion-pixel detector — will survey the entire night sky visible from its intended perch on Cerro Pachón in northern Chile once every three nights, allowing astronomers to monitor changes in stars and the motions of asteroids and everything else that moves in the sky. It will also allow researchers to map dark matter and the effects of the mysterious dark energy that is speeding the universe’s expansion.

Giant telescope project begins with a spin

Quote:
Imagine having to melt 24 tonnes of glass to make an 8.4-metre-wide telescope mirror. Now imagine if that were the easy part of the project.

The mirror-making for the ambitious Large Synoptic Survey Telescope (LSST) project is now underway, but the greatest challenges still lie ahead.

By 2015, the new $400 million observatory should begin recording the entire night sky every three days from its perch in the Chilean Andes. It will provide a vast treasure trove of data invaluable for tracking near-Earth asteroids, watching supernovae explosions and mulling the mysteries of dark matter and dark energy.

Before then, though, LSST project managers must perfect how to gather the faint starlight, capture it for posterity and share the images with the world.

Ummm... I think the hardest part will be securing all the funding...
