Media invited to ua mirror lab for july 23 spincasting

15.07.2005


Astronomers and supporters from eight institutions around the country who are developing the Giant Magellan Telescope (GMT) will gather at The University of Arizona Steward Observatory Mirror Lab on Saturday, July 23, to celebrate the casting of the first of seven 8.4- meter (27-foot) mirrors for the facility.

With this casting, the GMT becomes the first extremely large ground-based telescope to start construction.

The GMT will feature six giant off-axis mirrors around a seventh on-axis mirror. This arrangement will give it a 22-meter (72-foot) aperture, or 4.5 times the collecting area of any current optical telescope. It will have the resolving power of a 25.6-meter (84-foot) diameter telescope, or 10 times the resolution of the Hubble Space Telescope. The GMT is slated for completion in 2016 at a site in northern Chile. More about the project is online at www.gmto.org



Mirror Lab workers began loading 40,000 pounds of glass into the 8.4-meter (27-foot) diameter mirror mold at 6 a.m. Tuesday, July 12, and lowered the furnace lid over the glass at midday July 13. The furnace will be turned on Sunday, June 17, so the glass will melt at peak temperature, 2,150 degrees Fahrenheit (1,178 Celsius) on Saturday, July 23. The furnace will rotate at 5 revolutions per minute as the glass melts around the 1,681 hexagonal cores in the mold. This will produce a ’honeycomb’ mirror blank with a faceplate of the desired curvature. The honeycomb mirror will weigh only a fifth as much as a solid mirror of the same size. More about this mirror casting is online at uanews.org/spots/11355.html Media are welcome to interview scientists from GMT partner institutions during the event. NOTE: MEDIA WILL NEED PRESS BADGES FOR LAB ACCESS. GMT partners are the Carnegie Observatories, Harvard University, Smithsonian Astrophysical Observatory, University of Arizona, University of Michigan, Massachusetts Institute of Technology, University of Texas at Austin, and Texas A & M University.

press badges:

To cover the Mirror Lab casting event, news media must apply through the UA Office of University Communications for press badges to be picked up at the Mirror Lab beginning noon, July 23. Media can pick up their credentials with valid identification. To apply for badges, contact the UA Office of University Communications, 520-621-1877.

schedule & interview opportunities:

The Mirror Lab, underneath the east football stadium addition at Sixth Street and Warren Avenue, Tucson, will open to credentialed media at noon Saturday, July 23. Media will be asked to vacate the catwalk and furnace-lid-shelf viewing areas from between 3 p.m. and 5 p.m. to allow GMT guests access. Viewing areas on the mezzanine and at the south end of the casting lab will also be crowded at this time. An accurate model of the Giant Magellan Telescope will be on display at the south area of the casting lab. Lori Stiles from UA’s Office of University Communications and Elizabeth Alvarez del Castillo from UA’s Steward Observatory will help arrange interviews and interview areas.

photos/video:

For b-roll footage that includes steps in the GMT mirror-making process, contact the UA Office of University Communications, 520-621-1877. High-resolution photos of mold core installation, glass inspection, glass loading, spincasting, etc. can be downloaded from the UA Office of University Communications Web site, http://uanews.org after tomorrow (July 15) afternoon. Click on "ImageBase" under the Services column at the left of this page, and use "mirror lab" as the search word.

mirror lab media contacts:

Lori Stiles, UA Office of University Communications, 520-626-4402, lstiles@u.arizona.edu Elizabeth Alvarez del Castillo, UA Steward Observatory, 520-626-9778, ealvarez@as.arizona.edu Tina McDowell of the Carnegie Institution of Washington, 202-939-1120, tmcdowell@pst.ciw.edu, and Dan Brocious of the Smithsonian Whipple Observatory, 520-670-5706, dbrocious@cfa.harvard.edu, are other Tucson contacts during spincasting.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
