What specific task does the Canadian Launch Safety Office perform?

The correct choice accurately reflects the role of the Canadian Launch Safety Office in managing the airspace during rocket launches. This office is responsible for defining the necessary airspace requirements to ensure safe rocket operations. This involves coordinating with aviation authorities to establish safe zones and minimize risks for other air traffic in the vicinity of a launch site. By setting these airspace parameters, the office helps to prevent potential conflicts and ensures that launches can occur safely and efficiently.

The other functions, such as issuing approvals for all rocket-related activities, overseeing launch site safety, or managing the importation of rockets, are typically handled by different organizations or regulatory bodies, which do not fall under the specific domain of the Launch Safety Office. Thus, emphasizing the importance of the office's primary responsibility helps clarify its role in maintaining safety during rocketry events in Canada.
