NASA | Glory: The Rough Road to Space

The video discusses the challenges faced by spacecraft, particularly the Glory mission, in low earth polar orbits. It highlights the extreme thermal cycling experienced by spacecraft and the rigorous testing procedures conducted on the ground to simulate space conditions. These tests include vibration and thermal testing at both component and instrument levels, as well as environmental tests in vacuum chambers. The importance of pre-launch testing is emphasized to prevent mission failure, as any issues during launch cannot be rectified once the spacecraft is in space.

Why is it important to check the spacecraft for failures before launch?

Explain the consequences of inducing failures during the launch of the spacecraft.
