Statement of Work for LIBS Pit Volume Sensor (LPVS)

PR: 4200766756

1. Background

Goddard Space Flight Center has been tasked on a NASA award with Dr. Barbara

Cohen as the PI (Principal Investigator) to bring the Potassium Argon Laser Experiment (KArLE) measurement concept to TRL 6 in support of future Lunarand Planetary missions. The KArLE instrument concept requires for a particular collected sample that micropits are made on it for Laser Induced Breakdown Spectroscopy (LIBS). A LIBS Pit Volume Sensor (LPVS) is then needed to scan the sample before and after pits are made in order to identify the location and volume of the micropits. This work is a continuation of a earlier phase 1 concept study with GSFC, and in this procurement the below scope description would be required of the final phase of this effort. This is also a continuation of phase 2 proof of concept (PoC) development with design of linear stage implementation along with 2D image development that started with contract

80NSSC20P1103.

2. Scope

For this phase of the effort the vendor shall do the following with a TRL-6 LVPS:

1. Perform TRL6 build and data acquistion of the scanner to the following requirements:

1.1. The Vendor shall provide a detailed flight like build of the LVPS system.

1.2. The Vendor shall deliver a proper test configuration for pre and post environmental performance testing. This includes the necssary hardware and Ground Support Equipement (GSE) for this configuration. This includes, but not limited to software to drive the microimager, full camera control including exposure seetings, shutter speed, image capture, and trigger of 2D image, scan/drive and record laser spot during scanning. Environmental testing to be completed at GSFC.

1.3. The Vendor shall provide a detailed report and user manual for review and approval by NASA no later than 1 month before the planned delivery date to NASA. NASA will provide approval within 10 days of receipt. Absence of formal approval within the specified time frame may be construed as acceptance of the plan and authorization to proceed.

The user’s manual shall include a demonstration of performance prior to delivery to GSFC.

2. TRL-6 LPVS Calibration Activities:

2.1. The vendor shall verify the accuracy and precision of individual point locations and of pit volume over the range of natural sample attributes.

2.2. Develop a calibration procedure for the TRL-6 LPVS that references the data from the Proof-of-Concept scans of the NASA mineral sample.

3. Conduct an ambient verification test on NASA mineral sample for which there are available NASA-generated results obtained using a confocal scanning laser microscope.

4. Create a summary report of the results from items 1 through 4 by delivery of TRL-6 unit for Integration and Test (I& T).

3. Performance Requirements

The LVPS shall meet the following design requirements as developed on contract

80NSSC20P1103

1. Measure a pit with:

1.1. Area: 0.5 mm x 0.5 mm

1.2. Pit depth: 1 mm

1.3. Accuracy volume: <10% precision, <5% desired

2. Standoff distance: 15 cm from rock surface, with 1-2 cm of uncertainty

3. Total coarse scanning area: 6mmx6mm, containing 4x4 matrix of pits, separated by 1.5 mm center to center

4. Depth variation of coarse scan: 5mm

5. Coarse scan resolution: 100 μm in both lateral and depth

6. Measure a rock surface that has rough profile and wide range reflectivity

7. Acquisition speed: in < 5 minutes as goal (To be confirmed)

4. Deliverables and Delivery Schedule

The deliverables for the Phase 3 activities shall consist of:

1. TRL-6 design review within one month of award showing build and test plan of the LVPS

2. Due within 8 months after TRL-6 final design review –

a. Delivery of one LVPS unit that meets the performance requirements in section 3

b. Provide reporting of TRL6 build and represented test data sets prior to delivery to GSFC.

3. Due monthly – Technical status report, which can be delivered electronically or with a meeting.

4. Vendor to support KArLE weekly meetings.

5. Due at the end of the project

a. The optical and mechanical models for the LPVS that also identify preliminary interfaces (electrical, GSE, mechanical, and optical) for a more mature instrument.

b. A test report and technical summary that describes the LPVS concept, functionality, and test performance specifically when testing a sample for overall topography, identification of pits, and characterzations of the pit depth. The report will address all the items in the above scope.

c. Ground support equipment (including software) that can run the LVPS including a detailed user’s guide to support integration of the LVPS in the KArLE instrument and for pre and post enviormental testing that will be occurring at GSFC. All software must be compliant with NASA I&T security and accessibility regulations.

d. Provide post delivery support when needed by GSFC, and within the constraints of the remaining project budget. This can be determined at a later date as defined by both parties whether it be at GSFC or virtually.

5. Government-Furnished Equipment & Information

1. Test samples (various ~1cm sized materials with laser pits in them) to be measured by the LVPS. The materials will be safe for shipment and in no way space flight critical. Exact materials were provided and received by the vendor team to perform this task. Samples are expected to be returned back to GSFC once testing is completed.

2. GSFC will provide the necessary ICD of the KArLE GSE rack that will cover mechanical , electrical , and software with which the LVPS will connect to.

6. Provided Testing Facility

• vendor facility

• GSFC Building 22 and Building 33
