Nasa ’s Beyond Einstein Program: An Architecture for Implementation
Briefly describe the overall complexity level of instrument operations, and the data type (e.g., bits, images) and estimate of the total volume returned.
If you have identified any descope options that could provide significant cost savings, describe them, and at what level they put performance requirements and associated science objectives at risk.
In the area of science and instrumentation, what are the three primary technical issues or risks?
Fill in entries in the Instrument Table to the extent possible. If you have allocated contingency, please include as indicated; if not, provide just the current best estimate (CBE).
Optional details—If you have answers to the following detailed questions, please provide:
For the science instrumentation, describe any concept, feasibility, or definition studies already performed (to respond you may provide copies of concept study reports, technology implementation plans, etc.).
For instrument operations, provide a functional description of operational modes, and ground and on-orbit calibration schemes.
Describe the level of complexity associated with analyzing the data to achieve the scientific objectives of the investigation.
Provide an instrument development schedule if available.
Provide a schedule and plans for addressing any required technology developments, and the associated risks.
Describe the complexity of the instrument flight software, including an estimate of the number of lines of code.
Compare the scientific reach of your mission with that of other planned space- and ground-based missions.
Please answer the following as completely as possible:
Provide a brief descriptive overview of the mission design (launch, orbit, pointing strategy) and how it achieves the science requirements (e.g., if you need to cover the entire sky, how is it achieved?).
Provide entries in the mission design table to the extent possible. Those entries in italics are optional. For mass and power, provide contingency if it has been allocated; if not, provide just your current best estimate (CBE). To calculate margin, take the difference between the maximum possible value (e.g., launch vehicle capability) and the maximum expected value (CBE plus contingency).
Provide diagrams or drawings (if you have them) showing the observatory (payload and S/C) with the components labeled and a descriptive caption. If you have a diagram of the observatory in the launch vehicle fairing indicating clearance, please provide it.
Overall (including science, mission, instrument and S/C), what are the three primary risks?
