Thirty-Meter
Telescope Focuses on Two Candidate Sites
PASADENA, Calif.--After completing a worldwide survey unprecedented
in rigor and detail of astronomical sites for the Thirty-Meter
Telescope (TMT), the TMT Observatory Corporation board of directors
has selected two outstanding sites, one in each hemisphere, for
further consideration. Cerro Armazones lies in Chile's Atacama
Desert, and Mauna Kea is on Hawai'i Island.
The TMT observatory, which will be capable of peering back in
space and time to the era when the first stars and galaxies were
forming and will be able to directly image planets orbiting other
stars, will herald a new generation of telescopes.

Project
Manager's Corner: A New Leader for the National Optical Astronomy Observatory
Gary
H. Sanders, TMT Project Manager
TMT's
own David Silva, our Observatory Scientist, has been named as
the next Director of the US National Optical Astronomy Observatory.
(The AURA announcement is attached).
This is great recognition of what we already know; that David
is a star and a leader in astronomy. Now he will lead the US's
national observatory and take on an important role in assuring
the success of the US astronomy enterprise.

Science with Giant Telescopes: Public Participation in TMT and GMT
At the request of the NSF in 2002, NOAO created a Giant Segmented
Mirror
Telescope Science Working Group (GSMT
SWG). The main task of this community-based body is to develop the science
case and justification for any investment by NSF or other federal agencies in
the next generation of extremely large telescopes (ELTs).
To that end, the GSMT SWG has announced a workshop on public
participation in the future ELT projects. The workshop will take place
in Chicago on 15 - 18 June 2008. For more information, see the workshop
web page.
Construction
Review
Paul
Gillett
Imagine
buying a complex model kit and finding that there are no instructions
included. This is the case that every construction manager
faces when planning the construction of a project.
Construction
managers do have the advantage of experience of prior projects,
and even with the unique aspects of each project, much of that
experience provides the basic understanding required to build
the project. When construction managers step outside their experience
range, however, considerably more thought must go into the sequence
of construction.

Technology
Nugget—Progress towards Prototyping the Tip/Tilt Correcting
Stage for the TMT Adaptive Optics
Brent
Ellerbroek
Last
month, the TMT Adaptive Optics group met (virtually) with our
supplier CILAS to review their progress towards performing
a prototype demonstration of the tip/tilt stage for the TMT
adaptive optics system NFIRAOS. This stage will play the critical
roll of providing real-time image motion compensation to correct
for the effects of telescope vibration and the image wander introduced
by the atmosphere itself. In order to obtain the sharpest
possible images that are possible with a thirty-meter aperture,
NFIRAOS must correct this random image motion to a residual level
approximately one-two-hundredth the diameter of an uncorrected,
blurry image of a star. This is about one-ten-thousandth
of the distance that the star appears to move across the sky
during an interval of just one second!

Q & A
with Bill McVeigh
Bill McVeigh recently joined the TMT project to lead the implementation
of the
Project Management Controls System (PMCS) with a focus on the
development of the Integrated Project Schedule (IPS) and Earned
Value
Management System (EVMS).
Bill
has over 20 years experience designing and implementing project
management systems on NSF, DOE and DOD projects, such as ALMA,
ATST,
NSLSII, the Superconducting Super Collider and the Joint Striker
Fighter
(JSF) program.
Bill was interviewed at the TMT office by Jeff Oram.
