Payload Phase D Inspection Activities

Group 1) Sample Plate Inspections

Task Description: Inspect the sample plate dimensions and confirm that it has the intended flight samples and thermistor.

Completion Deadline: May 31, 2022

Team Member: Ali

Resources Required: Assembled Flight Sample Plate

Verification Activities: V-PLD-0011, V-PLD-0031, V-PLD-0042, V-PLD-0051, V-PLD-0061, V-PLD-0721, V-PLD-0291

Pass Criteria: Flight sample plate contains 24 flight samples, the gnomon, and one thermistor, contains no adhesives

Detailed Description:

Count the number of samples embedded within the sample plate assembly.

Confirm that the thermistor has been mounted to the sample plate.

Inspect the sample plate and confirm that it does not use adhesives near the samples.

Group 2) Camera Mounting Angle Inspection

Task Description: Verify that Payload measurements are taken at a 30 degrees +/- 3 angle to the samples

Completion Deadline: May 31, 2022

Team Member: Ali

Resources Required:

• Tools: Calipers, Protractor

• Hardware and Equipment: PLD upper shell (UMS-0027), Sample plate assembly (UMS-0019), Rear supports (UMS-0097)

• PPE: Cleanroom smock, face mask, gloves and goggles.

Verification Activities: V-PLD-0131

Pass Criteria: The sum of the camera mounting angle and sample plate mounting angle is 30 degrees +/- 3 degrees.

Test Procedures:

1. Assemble the rear support legs to the sample plate assembly (use Loctite on fasteners)

2. Measure the angle between the sample plate and rear legs using a protractor

3. Subtract that angle from 90 degrees, and then we have the angle between the sample plate and the upper shell.

4. Measure and record the heights of each of the PCB mounting posts on the Payload Upper Module.

2. Measure and record the heights of each corner of each payload camera as mounted on the Payload Control Board

3. Calculate the resulting angle between the normal vector at the centre of the camera board and the normal vector at the centre of the Payload Upper Module.

4. Measure the angle between the sample plate and structure.

5. Confirm that the sum of the camera mounting angle and sample plate mounting angle is 30 degrees +/- 3 degrees.

Group 3) Payload Weigh-ins

Task Description: Weigh the various Payload Flight Components

Completion Deadline: May 31, 2022

Team Member: Ali

Resources Required: digital scale, sample plate assembly, camera-Payload Control Board assembly, sample plate rear supports

Verification Activities: V-PLD-1790, V-PLD-0635

Pass Criteria: No single component has a mass greater than 250 grams and the sum of all masses is under 588 grams

Detailed Description:

Weigh and record the mass of each payload component (for this activity, the sample plate assembly and camera-Payload Control Board assembly without rear supports are considered single components).

Calculate the sum of all masses.

Group 4) Payload Control Board Inspection

Task Description: Inspect the Payload Control Board

Completion Deadline: May 31, 2022

Team Member: Ali

Resources Required: Payload Control Board

Verification Activities: V-PLD-0731

Pass Criteria: the payload control board has a thermistor mounted to it

Detailed Description:

Inspect the flight payload control board to verify that the payload control board has a thermistor mounted to it.

Group 5) Payload Surface Finishing

Task Description: confirm that all visible payload structural components are black anodized.

Completion Deadline: May 31, 2022

Team Member: Ali

Resources Required: sample plate assembly, sample plate rear supports

Verification Activities: V-PLD-0685, V-PLD-1051

Pass Criteria: Confirm that all parts that are to be black anodized, as indicated on the Payload ICD, are black anodized and that no parts have sharp edges.

Detailed Description:

Inspect all aluminum payload components and confirm that they are anodized as indicated on the Payload ICD.

With your thumb in a clean room-safe glove, carefully pass it over all outer part edges and confirm that none of these edges are sharp enough to cut through the glove.

Group 6) Gnomon Inspection

Task Description: Inspect the flight gnomon and confirm that it is less than 28 mm by 28 mm and has a matte finish.

Completion Deadline: May 31, 2022

Team Member: Ali

Resources Required: Flight gnomon, calipers

Verification Activities: R-PLD-0320, V-PLD-0231

Pass Criteria: The gnomon is less than 28 mm by 28 mm and has a matte finish.

Detailed Description:

Confirm that the gnomon is located on the geological sample plate and is less than 28mm by 28 mm.

Inspect the flight gnomon and verify that it has a matte surface finish.
