What was the cause of failure for the Orbiting Carbon Observatory and Glory satellites?

The Orbiting Carbon Observatory and Glory satellites both experienced failure due to vehicle launch issues. For the Orbiting Carbon Observatory, it was the result of a launch vehicle malfunction during the ascent phase. Specifically, a fairing separation failure caused it to plunge back into the ocean shortly after liftoff. Similarly, the Glory satellite's mission was compromised when its launch vehicle did not perform as expected, leading to a failure in reaching the intended orbit. Launch vehicle failures are critical incidents that can directly result in the loss of satellites, underscoring the importance of rocket integrity and operational performance during the early stages of a mission. This highlights why understanding the reliability and performance of launch vehicles is essential in the field of remote sensing and space missions.
