If a launch site borders an interstate freeway, what minimum distance must the high power launch pad be from the interstate?

• A. 750 feet
• B. 1500 feet
• C. 3000 feet
• D. 5280 feet (1 mile)

Answer: (B)

A sufficient safety buffer between the launch area and where the public can be is essential for high-power launches. When the site adjoins an interstate, the guideline sets the minimum distance from the launch pad to the roadway at 1,500 feet. This distance provides a conservative zone to account for possible debris, stage separation fragments, or a failure path that could carry components toward the road, helping keep motorists safe. The other distances don’t meet this required clearance for a public highway scenario, so they’re not acceptable as the minimum.
