USC Students Shatter Amateur Rocket Records with Aftershock II
A remarkable achievement unfolded on October 20, 2023, when a team of undergraduate students from the University of Southern California’s Rocket Propulsion Lab (RPL) launched the Aftershock II rocket, propelling it further and faster into space than any amateur rocket before it. Surpassing the previous record set more than 20 years ago by a Chinese rocket, Aftershock II soared to an astounding 470,000 feet (143,300 meters), and reached speeds of approximately 3,600 mph (5,800 km/h) or Mach 5.5.
Record-Breaking Launch in Black Rock Desert
The launch, conducted at the Black Rock Desert in Nevada, marked a significant milestone in amateur rocketry. Standing 14 feet tall and weighing 330 pounds, Aftershock II broke the sound barrier just two seconds after liftoff. The rocket’s engine burned out after 19 seconds, yet it continued ascending due to decreased atmospheric resistance, exiting Earth’s atmosphere a mere 85 seconds after launch. A nose cone separation and parachute deployment followed 92 seconds later, allowing for a safe reentry and landing.
“This achievement represents several engineering firsts,” stated Ryan Kraemer, an undergraduate mechanical engineering student and executive engineer of the RPL team. Not only did the rocket achieve unprecedented height, but it also utilized the most powerful solid-propellant motor ever fired by students.
Engineering Innovations Behind Aftershock II
The creation of Aftershock II showcased the innovative capabilities of student engineers. To enhance thermal protection critical at hypersonic speeds, the team employed new heat-resistant paint and titanium-coated fins, replacing previous carbon-based materials.
Kraemer pointed out: “Thermal protection at hypersonic speeds is a major challenge at the industry level.” The upgrades performed flawlessly, allowing the rocket to return largely intact despite the intense heating, which resulted in the fins changing color due to anodization.
Moreover, the students designed a new control unit, the High Altitude Module for Sensing, Telemetry, and Electronic Recovery (HASMTER), which was essential for tracking flight data and parachute deployment.
A Legacy of Excellence at USC
The Aftershock II mission is a continuation of RPL’s heritage of accomplishments. In 2019, USC’s student-led team became the first to launch a rocket past the Kármán line—the boundary marking the beginning of space. With this latest success, Aftershock II is only the second student rocket in history to reach such impressive heights.
“This is an exceptionally ambitious project not only for a student team but for any non-professional group of rocket engineers,” said Dan Erwin, chair of the USC Department of Astronautical Engineering. “It’s a testament to the excellence we seek to develop in our emerging astronautical engineers.”
Impact on the Future of Space Exploration
The success of Aftershock II signifies more than just a record-breaking achievement; it highlights the increasing capabilities of student-led initiatives in rocketry. This engineering feat inspires future generations of engineers and scientists, illustrating that remarkable advancements can arise from dedicated teamwork and innovation at academic institutions.

## Interview: Aftershock II – Breaking Barriers in Amateur Rocketry
**Host:** Welcome to World Today News! Today we’re delving into the groundbreaking achievement of the University of Southern California’s Rocket Propulsion Lab (RPL) and their record-breaking Aftershock II rocket. We are joined by two esteemed guests: Ryan Kraemer, an undergraduate mechanical engineering student and Executive Engineer of the RPL team, and Dr. Dan Erwin, Chair of the USC Department of Astronautical Engineering.
Welcome, gentlemen.
**Ryan:** Thank you for having us.
**Dr. Erwin:** It’s a pleasure to be here.
**Host**: Let’s start with the basics. Ryan, for our audience just getting wind of this incredible feat, can you describe what Aftershock II achieved and why it’s such a big deal?
**Ryan:** Absolutely. On October 20th, we successfully launched Aftershock II, a rocket designed and built by our team, to a height of 470,000 feet – that’s nearly 90 miles! This shatters the previous amateur rocket record set over 20 years ago and makes Aftershock II only the second student rocket in history to reach such heights.
**Host:** That’s incredible! Dr. Erwin, as the department chair overseeing this remarkable project, what are your thoughts on this accomplishment in the context of USC’s astronautical engineering programme?
**Dr. Erwin:** We are immensely proud of Ryan and the entire RPL team. This project epitomizes the spirit of innovation and excellence we strive to cultivate in our students. Reaching the fringes of space is an exceptional achievement, not just for a student team, but for any non-professional group. It speaks volumes about their dedication, talent, and the quality of education they receive at USC.
**Host**: Let’s dive deeper into the technical aspects. Ryan, can you tell us about the unique challenges the team faced in designing and building Aftershock II and how those challenges were overcome?
**Ryan**: We faced numerous hurdles, especially in developing thermal protection for the rocket’s voyage through the atmosphere at hypersonic speeds. To overcome this, we incorporated new heat-resistant paint and titanium-coated fins, replacing the previously used carbon-based materials. This allowed the rocket to withstand immense heat and return largely intact.
**(Theme: Innovation and Engineering) (Theme: Collaboration and Teamwork)**
**Host**: These are truly innovative solutions. Dr. Erwin, what are the broader implications of these advancements in engineering made by student teams like the RPL?
**Dr. Erwin**: This success highlights the important role student-led initiatives play in furthering technological progress. By pushing the boundaries of what’s possible, these students are inspiring future generations and contributing valuable knowledge to the field.
**Host**:
It’s inspiring to see this firsthand. Ryan, can you share some insights into the collaborative effort within the RPL team throughout this journey?
**Ryan:** The RPL team is a close-knit group of dedicated individuals who share a passion for rocketry. From design and construction to testing and launch, we worked together tirelessly, sharing knowledge, supporting each other, and pushing beyond our perceived limitations. It’s truly a testament to the power of teamwork.
**(Theme: Future Impact and Inspiration)
**Host**: Driven by passion and teamwork. I love it! Dr. Erwin, looking towards the future, how might the success of Aftershock II influence the future of space exploration and the role of student-led projects?
**Dr. Erwin:** This achievement sends a powerful message – the future of space exploration is not limited to large-scale government agencies or corporations. Student teams, with their ingenuity and passion, are making significant contributions and paving the way for new possibilities in space exploration. We’re likely to see even more ambitious projects emerge from academic institutions in the years to come.
**Host**: This is truly an exciting time for space exploration. Ryan, what message do you have for aspiring engineers and future pioneers who might be watching right now?
**Ryan:** Don’t be afraid to dream big and chase your passions. Even seemingly impossible feats can be achieved with dedication, teamwork, and a willingness to push the boundaries.
