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.

Traveler IV Flight Videos……(Waiting for Space Confirmation!)

While we wait for USC to confirm the altitude obtained by their Traveler IV rocket, they have posted some video of the launch to quench our thirst.
If you listen carefully you can hear a call out of 49 km which surpasses their Fathom II rocket flight to 43 km and hence their highest flying rocket to date. But did it reach 100 km? we will just have to wait a little longer!

Stratos IV Launch Delay

As per the below post, the team has decided to reschedule the launch to Summer 2020. Stratos IV is expected to reach the Karman line, they have some fierce competition launching this year so we will have to see how it pans out for that first place!

Video Caption: MASA is building a liquid rocket capable of reaching space, also known as the Karman Line. We need your help to make this rocket reach 100 km. Check out our crowdfunder at If you would like to connect with the MASA team, feel free to reach out to us at

We are extremely for all of those who have given to our campaign and our sponsors who are continually sponsoring the team.

Thank you to Kulite, Boeing, Rego, Raytheon, Northrop Grumman, Graphite Store (, and XWinder for their support.

Princeton Aiming for Space Again

The team had told me late last year they will be attempting their space shot again, now it is finally official!
The first launch of their two-stage rocket, unfortunately, suffered a failed ignition of the sustainer, the vehicle performed flawlessly and the sustainer was recovered. By the recent post, it looks like they will have the ignition issues sorted this time round!

Check out the team’s website here for more rocket information!
