Tara

Tare refers to hardware that is not used for the actual flight. This hardware is used specifically for measurements and testing of test objects without taking overruns into account. Tare is an important part of testing and validation to ensure that flight systems meet requirements and function correctly.

Use of Tara

Tara is used in various phases of the development and testing of space systems:

Measurements and tests: Tare is used to perform accurate measurements and tests on test objects. This includes checking masses, weights, structural properties and other critical parameters.
Validation and verification: Tara plays a crucial role in the validation and verification of systems. It helps to ensure that all components comply with the specifications and function correctly.
Calibration: Tare can also be used to calibrate measuring devices and systems to ensure that measurements are accurate and reliable.

Examples for Tara

Tare can take different forms depending on the specific requirements of the measurements and tests:

Test weights: Special weights used to measure and calibrate the mass and weight of test objects.
Measuring devices: Devices and equipment specifically designed to perform measurements, such as sensors, probes and other instruments.
Brackets and adapters: Mechanical components used to hold and position test objects so that accurate measurements can be made.

Meaning of Tara

Tare is of great importance for carrying out precise and reliable measurements and tests:

Accuracy: Tara makes it possible to carry out precise measurements, which are crucial for the validation and verification of systems.
Reliability: By using tare, tests and measurements can be carried out reliably and reproducibly.
Security: Tara contributes to the safety of tests and measurements by ensuring that all test objects are handled correctly and safely.

Difference between tare and flight hardware

It is important to distinguish tare from the actual flight hardware:

Tara: Is not used for flight and is used exclusively for carrying out measurements and tests.
Flight hardware: Used for actual flight and operation in space and must withstand the extreme conditions of launch and space.
