Students' 'homemade' rocket soars faster and farther into space than any other amateur spacecraft — smashing 20-year records
Aftershock II, a new rocket built by students at the University of Southern California, recently broke a number of 20-year-old amateur spaceflight records for altitude, power and speed. It reached more than 470,000 feet above Earth's surface and went "hypersonic."
At this point, the nose cone separated from the rest of the rocket and deployed a parachute so it could safely reenter the atmosphere and touch down in the desert, where it was collected by the RPL team for analysis. In 2019, another group became the first student-led team to launch a rocket past the Kármán line — the imaginary boundary where space officially begins, Live Science's sister site Space.com previously reported.
