WFIRST - IFS SPICA FTS Core CASTOR Optical Chain EPPE Payload

—SPICA Scan Mechanism


Technology Spin-off from Darwin Delay Line

—SPICA


Magnetic Guiding in Zero Gravity

—Magnetic Guiding at 4 Kelvin


Pros Cons

• Numerous harness to 4K zone

• How to cool floating mass

• 1G offload system for test

• Vibrations = strong correction current

• Elaborate control electronic (6 servos + redundancy)

• Frictionless allows nm control

• No stroke limitation (6 cm target)

• 0 hold force at any position

Canadian 2012 phase 0 study revealed several technical challenges

Proposal to Consortium: Reactionless Stiffness Compensated Mechanism


—New Concept Solves:


Pros Cons

• Numerous harness to 4K zone

• How to cool floating mass

• 1G offload system for test

• Vibrations = strong correction current

• Elaborate control electronic (6 servos + redundancy)

• Frictionless allows nm control

• No stroke limitation (6 cm target) Ok for 6 cm

• 0 hold force at any positionPassive magnetic arrangement minimizes hold force(~10 x)

2018: Consortium changed SAFARI design to ABB concept

—Stiffness Compensation


—Nanometer-Level Light Tight Metrology


Retro-reflector

FiberInjector

FiberCirculator

Lasersource

Detector

—TRL Improvement Work to Mission Selection (2021)


SPICA SAFARI Improvement still required on:

• Mass

• Power dissipation @ 4K

• Magnetic & laser disturbance to science detector

• Survivability to launch vibration (launch lock?)

• Flight electronic design

• Redundancy vs reliability

• Life testing @ 4K

• …

From demonstration prototype to being ready for FFP costing of flight deliverables

—

• Inspire/attract/retain highly qualified staff (cool projects are not only in US or Europe!)

• Infuse new technologies, knowledge & test equipment through the whole supply chain

• Multi-year project brings much needed stability

• Asset for makerting & sales (conveys industrial expertise)

Space Astronomy; the (optical) Industry PerspectiveThe benefits

—

• Highly Innovative each time = ++ R&D = prone to cost growth = financially risky if Firm Fixed Price

èSTDPs, Phase 0 and A are critically important to refine cost estimates

• Domestic government market by definition (e.g. Canada-Europe Trade Agreement)

è Export opportunities mainly through other application & diversification (e.g. Earth Obs.)

• Niche equipment often ~10-20 years ahead of civil applications (e.g. CCDs)

• Maintain workforce through mission gaps…
