Traveler IV Reaches Space!

Congrats to the team at USCRPL, whose Traveler IV rocket reached 339,800 ft (103.6 km) on April 21st from Spaceport America, becoming the first ever student rocket to reach and exceed the recognised boundary of space, 328,084 ft (100 km).

For all you wondering how they determined the peak altitude, the team have published a white paper explaining their sensor package and ultimately how they were able to determine apogee with a 90% confidence, you can read the paper here.

A blog post of the flight can be found here.

Video Caption: On April 21, 2019, we, the USC Rocket Propulsion Lab, launched our latest space-shot rocket, Traveler IV, out of Spaceport America. Traveler IV reached an apogee of 339,800 ft with a confidence of 90% of having crossed the internationally-recognized border between Earth’s atmosphere and space known as the Kármán line. By flying higher than the Kármán line, Traveler IV has broken the world record for the highest altitude ever reached by a vehicle entirely designed and built by a collegiate rocketry team. USCRPL thanks the alumni, faculty, department staff, parents, the university, and all others who have supported the lab’s fourteen-year-long dream.
Even greater things lie ahead.

Keep an eye out for the full-length documentary coming soon! — About us: USCRPL is the world’s premier undergraduate research group for experimental rocket technologies. Founded in the 2004-2005 school year with the mission of putting a scratch-built rocket into space, USCRPL has spent the last 14 years becoming a world leader in the design, manufacturing, and testing of small, low-budget, high-performance rockets. RPL’s members are all undergraduates, but alumni work across the space industry at organizations such as SpaceX, Blue Origin, and NASA, as well as RPL alumnus-founded startups like Relativity Space, Ursa Major Technologies, and 121C.

Liquid Rocket Engines 1 : Design

Charlie Garcia, an MIT student is on a quest to build a liquid rocket engine and wants you to follow along! Starting a video series, you can learn and follow his progress and see what it actually takes to achieve fire!

Video Caption: I explain how I chose very high level parameters for my rocket engine I’ll be working on over the summer.

SS2S Two-Stage Launch

Video Caption: Uploaded on May 3, 2016

The first launch of the Sugar Shot to Space small scale 2-stage rocket. Rained in the morning and never cleared so launch was done without igniting the sustainer to stay below the cloud ceiling. 100mm ( 4 inch ) booster staging to a 75mm ( 3 inch ) sustainer, both having been launched successfully previously separately.
