NASA | TIRS TVAC1 Opening the Vacuum Chamber

The video tutorial covers the testing and handling of a thermal instrument at Goddard. It details the setup in a thermal vacuum chamber, the inspection process, and the careful movement of the equipment on a sled. Safety measures are emphasized, including grounding to prevent static damage and covering the equipment to avoid contamination. The equipment is then transported on a cushion of air to a clean room for final testing, where it has been performing beyond expectations.

What is the primary purpose of using a thermal vacuum chamber in the testing process?

• To simulate space conditions by controlling temperature and pressure

• To enhance the visual inspection of the instrument

• To increase the speed of testing

• To reduce the cost of testing

Why is it important to document the layout of wires during the inspection?

• To improve the speed of testing

• To ensure the wires are aesthetically pleasing

• To make the instrument lighter

• To prevent accidental contact that could add heat load

What is the role of the grounding wire during the sled movement?

• To keep the sled stable

• To prevent static electricity from damaging the instrument

• To make the sled move faster

• To reduce the weight of the sled

What is the main reason for covering the equipment before opening the protective tent?

• To keep the equipment warm

• To prevent dust and particulates from contaminating the instrument

• To reduce noise during movement

• To make it look more professional

How does the platform move down the hall with the instrument on top?

• Manually carried by the team

• Using a conveyor belt

• On a cushion of air like a hovercraft

• On wheels

What is emphasized as the most important aspect when moving the equipment?

• Speed

• Safety

• Efficiency

• Cost

What has been the performance of the instrument according to the final section?

• It has met the basic requirements

• It has exceeded the requirements and performed beautifully

• It has underperformed

• It has not been tested yet
