When can you approach a rocket that has misfired?

The correct approach after a rocket misfire is to wait for one minute and obtain permission from a range official before approaching the rocket. This protocol is designed to ensure safety because rockets that misfire may still have an igniter that could potentially ignite the rocket after an initial failure. Waiting for a specific duration allows residual propellants to stabilize and decreases the risk of an unexpected ignition.

Additionally, involving a range official emphasizes that safety protocols are adhered to by trained personnel, ensuring that an assessment of the situation is conducted professionally. This helps to keep all individuals present at the launch site informed and safe.

The other time frames do not include the necessary range official's authorization or could be interpreted as too soon to safely approach the rocket. Hence, timing and protocol both play crucial roles in ensuring safety in rocketry operations.
