The Minnesota Space Grant is hosting both a Rocketry Competition and a Rocketry Challenge on the weekend of May 16-17, 2026.
Saturday, May 16:
The first day runs from 5 p.m. to 9 p.m. in Akerman Hall at the University of Minnesota (110 SE Union St, Minneapolis), with safety checks and competition team oral presentations to judges
Sunday, May 17:
The event’s second day runs from 9 a.m. to 4 p.m. with a rocket fly-off at the Tripoli Minnesota high-power rocketry club launch site just outside of North Branch.
Spectators are welcome.
The Rocketry Competition teams are from the University of Minnesota Twin Cities, Macalester College, Bethel University, Augsburg University, and Normandale Community College, as well as teams from Iowa, Wisconsin, Michigan, Maryland, North Dakota, Ohio, Louisiana, Tennessee, and one team from overseas.
The Rocketry Challenge teams are from Century (Community) College, Anoka-Ramsey Community College, Fond du Lac Tribal and Community College, St. Johns University and the College of St. Benedict, Minnesota State Moorhead, Gustavus Adolphus College, and University of Minnesota Morris. (The Rocketry Challenge is for newer, less-experienced student teams.)
Competition Task:
The “Secret-Message Challenge”
Summary Description
Student teams will design and construct a single-motor, single-stage, high-power rocket and fly twice during the competition on an AeroTech H195NT-14A DMS motor and on a Cesaroni 382I170-14A motor. Note: These motors have different diameters.
This year the challenges are:
(A) Have the rocket carry a down-facing camera system to collect in-flight video watching a set of up-facing bright lights spread out near the launch pads that are flashing a repeating coded message (about 10 seconds long, with new patterns displayed approximately every half-second) and keep the set of lights in view and be able to distinguish the patterns for as long as possible, during both ascent and descent.
(B) Implement a roll-control mechanism, with indicator lights in view of the down-facing camera system, showing what the mechanism is trying to do. Demonstrate the ability to control the roll of the rocket on ascent (at least roll CW 90°, then roll CCW 90°). Note: Teams can try to use the roll control capability to keep the set of lights in view.
(C) Have the rocket carry a “non-commercial” (i.e., not sold for rocketry) data-logging sensor suite and use it to log at least once a second (even faster would be better) GPS (latitude, longitude, and altitude), ambient pressure, 3-axis acceleration, 3-axis roll, and status of the roll control mechanism during the entire flight.
Bonus points will be given to:
(1) Teams whose member(s) increase their certification level(s) using individually-built rockets (in parallel with the (team-built) competition rocket).
(2) Teams that implement a telemetry system with which they can transmit information about the pattern of lights (i.e., evidence that they “got the message,” even if they cannot decode it (yet)) to a ground station located near the LCO table within 10 minutes of landing and before going out to recover the rocket.
(3) Teams that are able to decode the message (more bonus points given to teams that decode the message more quickly).
All fabrication work on the rocket(s), except for possibly machining of plastic and/or metal parts, must be performed by students.
