Cosmic RAy Telescope for the Effects of Radiation

CRaTER Team

• CRaTER is a multi-Institutional Project lead by Harlan Spence of B.U.– Aerospace Corporation

– Massachusetts Institute of Technology

– National Oceanographic and Atmospheric Administration

– University of Tennessee

• Science Mission involves all of the Institutions

• Flight Hardware Design, Fabrication, Test & Calibration is being done by three of the Institutions

Cosmic RAy Telescope for the Effects of Radiation

What are we building?• Flight Model CRaTER Instrument (Deliverable to NASA)

– Fully Qualified and Calibrated

• Flight Spare Instrument– Fully Qualified and Calibrated– The incremental costs associated with putting spare components together is minimal– CRaTER Project has only budgeted for a few spare detectors. Yield may be a factor– The science team will utilize the spare for instrument characterization at different particle accelerators,

both pre and post launch to help develop SOC analysis tools. Using the spare reduces risk to the flight unit.

• Engineering Model Instrument– Fairly high fidelity model– Not Flyable

• Mass/CG Simulator• Command & Data Handling Simulator

– It may be possible that we will use the EM for this function, but still under review.

• M&E GSE for internal CRaTER project use– Will be used up thru post shipment testing at NASA-GSFC

• Various jigs and fixtures for instrument testing and calibration• Shipping containers for instrument transportation

CRaTER Project Schedule

• The CRaTER Project Schedule tracks the NASA LRO Top Level Schedule– LRO schedule being used by CRaTER currently at Rev 0.7– The CRaTER Project Schedule Holy Grail

• A fully qualified & calibrated flight unit to NASA-GSFC by Oct 2007

• Even with the some problems getting the project started, the schedule prognosis is plausible.• After I-PDR, the next technical milestone will be the submittal of the of the Engineering Model

detector technical specification to Micron Semiconductor for quotation and subsequent procurement.

– Oct 2005

• Near I-PDR, the next programmatic milestones will be the issuance of a no cost extension to the Phase ABCbridge contract and then completion of the Phase CDE contract (extension)

– Current estimation for the completion of the Phase CDE contract extension signoff is before the end of November 2005

• CRaTER Risk Management methodology detailed in CRaTER plan doc# 32-01202

• Classification of risk modeled on NASA methodology– Likelihood and impact assessment.

• At I-PDR, there is one green level identified risk.– The identified risk is the possibility of receiving the flight detectors and finding or

developing problems with them during flight instrument I&T• These detectors are “made to order” and typically have a 6 month lead time.

• 2 detectors have been beam tested already, two more on order

• 6 detectors will have been test in the EM model prior to I-CDR

• CRaTER Plans to build a flight and flight spare instrument
