Which of the following is a mitigation strategy for rocket accidents?

The correct response focuses on pre-launch safety assessments as a crucial mitigation strategy for rocket accidents. This approach involves conducting thorough evaluations and checks before any launch takes place, ensuring that all systems are functioning correctly and any potential hazards are identified and addressed. These assessments can include reviewing design specifications, evaluating materials, and verifying that safety protocols are in place for both the rocket and the launch site.

By implementing rigorous safety assessments, potential issues can be caught early, which significantly reduces the risk of accidents during the launch process. This proactive measure is essential in the field of rocketry, where the complexities and potential dangers associated with high-speed launches and volatile materials require meticulous preparation and oversight.

In contrast, other options like encouraging public events or post-launch celebrations do not directly contribute to accident prevention or risk mitigation, and increasing the rocket's weight may introduce new issues rather than addressing safety concerns. Thus, pre-launch safety assessments are vital to ensuring a safer launch environment.
