Aftershock II has officially become the highest and fastest amateur rocket of all time! Following its successful launch to space on Oct. 20, 2024, an internal data review concluded a world-record altitude of 470,400 ft and a top speed of 5,283 ft/s (Mach 5.5).
The University of Southern California Rocket Propulsion Lab is proud to announce our upcoming static fire test, Baja Blast, on Saturday, April 19th at the Reaction Research Society’s Mojave Test Site! This test will also be live-streamed on our youtube channel!
Baja Blast is a liner-bonded, monolithic, finocyl-geometry solid propellant rocket motor being tested in a new type of carbon composite case, representing a large iteration on the lab's motor and case designs.
We are excited to announce the USCRPL 2025 Hi-AL Kiwi and first-ever Emu Characterization Campaigns! This test campaign comprises over fifteen solid propellant motor firings to characterize the new propellant Hi-AL. (1/4)
Hi-AL is a proprietary high aluminum content propellant that USCRPL’s students manufacture at Exquadrum's facilities. With @exquadrum’s infrastructural support, Hi-AL has been in development for the better part of a decade. (3/4)

One year after Shockwave and 6 months after Aftershock I, we have successfully flown Aftershock II to space.
More details to come soon as we process the data!

Targeting to launch Aftershock II in T-7 days from Blackrock Desert, NV.
Built in only 3 months, we’ve made several key improvements from ASI and we’re hopeful it will succeed!
Space or Nothing! ✌️
Officially announcing RPL next spaceshot, Aftershock II. Using the learnings from the failure of Aftershock I, we are coming back stronger than ever and are once again striving to launch the highest and fastest traveling student-built rocket of all time!
Excited to showcase our members who had internships this summer, totaling 24 internships at 13 different companies!
