Internal analysis shows the students’ vehicle, called Traveler IV, crossed the Karman Line that represents the international boundary of space at an altitude of 62 miles (100 kilometers). The analysis confirmed the achievement with 90% certainty, USC officials added.
Students launched the rocket April 21 from New Mexico’s Spaceport America, where future space-tourism provider Virgin Galactic is the anchor tenant. The rocket successfully flew aloft at 7:30 a.m. local time, reaching a maximum recorded altitude of 339,800 feet (64.4 miles, or 103.6 km), and a top speed of 3,386 mph (5,449 km/hr).
“[The achievement] makes Traveler IV the first entirely student-designed-and-built rocket to fly to space, as well as the highest flying such craft — doubling the previous altitude record — and the first university rocket to be successfully recovered from space,” USC officials said in the statement.
More than 80 undergraduates participated in the rocket’s design, construction and launch effort, which included receiving clearance from the Federal Aviation Administration for the launch. This was the university’s fourth attempt to breach the boundary of space.
“After nearly 15 years and probably over a million hours of work, RPL has finally achieved its goal of being the first student group to launch the first student-designed and built rocket past the Karman line,” lead engineer Dennis Smalling, an astronautical engineer who graduated from USC this spring, said in the statement.
USC identified several other top contenders for first space shot, including Princeton University; the Massachusetts Institute of Technology; Boston University; the University of California, San Diego; the University of California, Berkeley; and Portland State University. International competitors included Delft University (Netherlands) and TU Vien (Austria).
