GLAST Mission - LAT Project
DOE/NASA Review, March 31, 2004
Introduction
• The transition to the first flight units has had the expected
challenges and impacts
– The LAT team is effectively stepping up to solve problems
• Producing flight hardware
– First tower integrated with the grid this fiscal year
– Tight, success-oriented schedule
• We will see risk to the instrument delivery date until we have
established a production rate history
– Plan has 9 weeks float to delivery for observatory
integration
• Overall project contingency is OK
– Project is 65% complete
– Contingency is 29% of cost to go
• Funding in the current fiscal year is an issue
– All funding for FY04 is allocated
