LHO LEN 2005 meeting 2LIGO- G050565-00-W
LIGO is doing well
• LIGO construction and commissioning of the Initial LIGO detectors have been a success
• LIGO has built a large international collaboration of approximately 500 scientists on four continents and leads the world in gravitational wave research
• LIGO is embarking on a long search (more than one year) that may well make first detection of gravitational waves
• LIGO data analysis has provided the premier test drive for the national GRID-computing & Virtual Data infrastructure
• LIGO’s experimental technology development program has been a resounding success and continues to contribute to national technical capabilities
• NSF and NSB have recommended construction of Advanced LIGO, which will extend LIGO’s world-leading sensitivity by a huge factor and ensure that gravitational-wave astronomy takes off; scheduled by OMB for FY08 start

Funding Issues
• US funding for science has continued to erode» National Academy study chaired by Norman Augustine to investigate
consequences and remedies at request of US Senate
• LIGO has needed to tighten up & reduce operating staff
• OMB scheduled start for AdLIGO is a slip of one year from NSB recommendation
• UK funding of AdLIGO has already begun and progress toward funding by Germany continues
• LIGO Science Education Center funded ($5M) by NSF» Exploratorium has delivered first wave of exhibits» Active professional development program in place (Southern U. and LaSIP /
LaGEAR-UP)» Center construction begins next week
• LIGO Hanford Observatory funded ($50K) by NSF to develop GRID-based access to LIGO environmental data for “Interactions in Understanding the Universe”

LIGO Management
• LIGO Laboratory & LIGO Scientific Collaboration managements have been restructured» Now LIGO has a single directorate including LSC Spokeperson
» Caltech/MIT LIGO Oversight Committee expanded to include LSC “stakeholder-institution” representation and at-large, non-voting LSC technical advisors
• Barry Barish has retired from Caltech» Barish will remain as emeritus professor and will direct the
International Linear Collider (ILC) construction effort
» Stan Whitcomb (formerly Deputy Director) is Acting Director
» LIGO Director Search Committee has made recommendations to Oversight Committee
» Hope to begin new year with new director
