The payloads -- ultraviolet telescopes known as spectrographs -- are being built at CU-Boulder's Center for Astrophysics and Space Astronomy and will be launched from White Sands Missile Range in New Mexico beginning in 2010. ❋ Unknown (2009)
And all the while he was inventing and building cameras and spectrographs. ❋ Ann Finkbeiner (2010)
BACK AT PRINCETON, having designed the spectrographs and telescope, Jim went down to the Peyton Hall basement, closed the door, and started work on his camera. ❋ Ann Finkbeiner (2010)
Like the camera, the spectrographs worked beautifully pretty much from the start. ❋ Ann Finkbeiner (2010)
And finally, it funneled its data into the target selection pipeline, which decided which stars and galaxies should be reobserved with spectrographs to get their spectra. ❋ Ann Finkbeiner (2010)
It could take the spectra of hundreds of thousands of galaxies—the same survey with current spectrographs would take several thousand years—and the images of tens of millions of galaxies. ❋ Ann Finkbeiner (2010)
They figured the spectrographs would cost a little over $1 million, the camera would cost $2.7 million, and no one knew how expensive the big CCDs would be. ❋ Ann Finkbeiner (2010)
So while astronomers could make marvelous photographs and spectrographs (which break down light for analysis) of individual objects, they had trouble seeing the forest for the trees. ❋ Timothy Ferris (2010)
Alan Uomoto and Steve Smee at Hopkins had finished the spectrographs and in the spring of 1999 had installed them on the telescope. ❋ Ann Finkbeiner (2010)
A newly hired UW engineer named French Leger ran into a problem with a large rotating disk, attached to the telescope, to which the camera and spectrographs are attached. ❋ Ann Finkbeiner (2010)
But the spectrographs themselves were only one step in getting spectra into an archive, and the whole spectroscopic system was a complicated little factory. ❋ Ann Finkbeiner (2010)
But then Hopkins had joined, and along with responsibility for the spectrographs came hints and murmurs that it was also interested in putting together the archive. ❋ Ann Finkbeiner (2010)
He noticed that on top of Bloomberg was a telescope dome and wondered what kind of telescope was in it, so he asked Alan Uomoto, who was building the spectrographs, about it. ❋ Ann Finkbeiner (2010)
It was operating in fits and starts—parts of the telescope kept breaking, observers ran into problems, the weather was awful—but the data from the camera and spectrographs ran through the photometric and spectroscopic pipelines and out the other end. ❋ Ann Finkbeiner (2010)
They worked two per night and made all the nightly decisions about whether to observe, when to open up, whether to use the camera or spectrographs, what parts of the sky to point to, when to close. ❋ Ann Finkbeiner (2010)
The Sloan had two spectrographs mounted behind the primary mirror on either side of the camera; the camera can come and go, but the spectrographs stay put. ❋ Ann Finkbeiner (2010)
And then the cartridge, plugged plate, and blocks holding 640 fibers altogether—the whole affair now looking like a framed pizza pan with its hair sticking straight up—is carted out to the telescope and plugged into the spectrographs. ❋ Ann Finkbeiner (2010)
But on October 19, 1999, an Apache Point engineer named Jon Brinkmann was showing another engineer, John Briggs, where on the telescope the spectrographs were mounted. ❋ Ann Finkbeiner (2010)
Once the spectrographs were installed, Uomoto moved on to other projects, and Smee—being a barely trained, soft-money engineer no longer getting paid—went off to graduate school to get a PhD in mechanical engineering. ❋ Ann Finkbeiner (2010)
Light from each one of 640 targeted objects hits its exact hole in the plugged plate and runs down its own fiber to the spectrographs, which turn out 640 tiny rainbows, captured on CCDs and recorded on tape. ❋ Ann Finkbeiner (2010)
