What was the specific apogee reached by USCRPL's Aftershock II during its record flight?
Answer
143 kilometers
The Aftershock II flight achieved a peak altitude, or apogee, of 143 kilometers, which is equivalent to 470,000 feet. This performance significantly surpassed the preceding record established by CSXT’s *GoFast* in 2004, which peaked at 116 kilometers. The margin of victory was substantial, exceeding the old record by 90,000 feet. This immense altitude demonstrates the high performance achievable with advanced solid-propellant motors in the amateur spaceflight community.
