E/PO Rocket Test

Alex’s Rocket Launch (Video)

Our student employee here at the Education and Public Outreach group, Alex Berlanga, recently tested out a new, smaller version of our S4 rocket at the Sonoma State University campus. As you can see in the above video, the test went well with an E class motor. After a bit of a hike, the team managed to successfully recover the rocket and the new payload. Smaller rockets can be launched in a wider variety of places, built more cost effectively, and launched without special certification. We look forward to more successful tests of this platform to come! Alex is a summer intern from Santa Rosa Junior College, whose internship was funded through the California Space Grant Consortium.

Competition Results

Here are the final results of the 2015 S4 competition.

Congratulations to Newark Memorial High School Team 1 (Descent Rate) for winning first place, and the $750 prize. The judges were impressed by the team’s computer modeling and data analysis, as well as their outreach efforts and rocketry on the playa.

Congratulations to Northview High School (Bird Migration) for winning second place ($250). The judges appreciated the team’s spirit, outreach efforts, 3D print designs and rocketry on the playa.

Congratulations to Newark Memorial High School Team 3 (Wind Speed) for the “Best Flight” award for rocketry on the playa and the novel design that included a third party anemometer. This team will receive $100 and a trophy for best flight.


We hope that everyone learned a lot from their Black Rock experiences. It was great fun, and we came away with valuable lessons learned for future similar events.

S4 Launches at Black Rock Desert, June 19-21

On June 19th through June 21st, 2015, five high school teams (and their rockets) made their way to the Black Rock Desert in Nevada to launch their S4 based payloads in the climax to this year’s competition. The teams were as follows:

Team 1
School: Newark Memorial High School; Newark, CA
Experiment: Atmospheric effects on descent rates

Team 2
School: Newark Memorial High School; Newark, CA
Experiment: Precision of S4 Payload Sensors

Team 3
School: Newark Memorial High School; Newark, CA
Experiment: Establishing a Model for Wind Speed Variability

Team 4
School: Elena L. Christian Junior High School; St. Croix, U.S. Virgin Islands
Experiment: Comparing Relative Air Humidity in Arid and Equatorial Regions

Team 5
School: Sylvania Northview High School; Sylvania, OH
Experiment: Migration Patterns of North American Birds

Each group was given the opportunity to fly their custom made sensor payloads on high powered rockets under the guidance of rocketry experts from AeroPac and payload experts from Sonoma State University’s Education and Public Outreach team. The S4 payloads were provided to the schools, with necessary soldering, programming and securing required to be performed by the students. Each student team then had to decide which sensors were appropriate for the experiments, and obtain and fit those sensors on their own. Most teams further designed rocket boosters and payload sections customized for their particular needs.

After launching their rockets, retrieving data and processing that data, teams prepared presentations for the judges. In these presentations the teams explained their design concepts, the goal of their experiment, public outreach efforts and the results of their flights. Most teams presented in the desert soon after their final flights, with additional analysis in presentations sent after the event for a final judging on June 30, 2015.

Flight operations ended around noon on Sunday as the wind picked up considerably. This was a memorable event for all the participants, and provided valuable opportunity to learn real life applications of engineering and science skills. The SSU S4 team was on hand to provide telemetry service, troubleshooting assistance and to record video of the event, which will be shared in a post soon to follow.

The S4 program follows participation in the Team America Rocketry Challenge (TARC), with proposals solicited from the top twenty five teams to compete at TARC. S4 is sponsored and supported by the Education and Public Outreach group at Sonoma State University, Tripoli Rocketry Association’s AeroPac prefecture and the National Association of Rocketry, which sponsored the cash prizes to winning teams.
