The Utah Rocket Club is an organization supporting safe activities through the sport and science of hobby rocketry. UROC has been active in Utah since the early 1980s.

We welcome anyone with an interest in rocketry to join us. Our membership spans all ages and families are welcome.

Over sees the checking in of rockets and assigns the rocket to a particular pad. Takes a look at the rocket to see if it is fit to fly. Make sure that the motor has been mounted correctly, fins secure, and launch lugs are attached correctly. Then assigns the rocket to a pad. Should be certified level 2 or higher through either the National Association of Rocketry or the Tripoli Rocketry Association. The RSO is responsible for the overall safety of the range, not just rockets but all activities taking place at the launch site. The RSO has ultimate say in decisions concerning safety.

  1. Confirm that the flyer is certified to fly the rocket/motor combination presented. This can be verified via the flyer's membership card from either association. 
  2. Weigh the rocket and determine if the motor is appropriate for the rocket's weight using the motor charts available at the RSO table.
  3. Verify that the motor being used is an approved rocket motor and provides a thrust to weight ratio (TWR) of greater than 4 and have a delay that will ensure safe recovery.
  4. Verify the stability of the rocket. The rocket should exhibit at least 2 caliber's of static stability, or be of a proven design. If the rocket looks marginal the RSO can ask the Flyer if the rocket has flown safely on the same motor or require proof of stability (simulation output).
  5. Verify that the rocket will not exceed the site altitude waiver.
  6. Verify that the ignitor is not in the motor.
  7. Determine if the recovery system will operate properly. Check with the individual to verify if they have the proper delay, fresh batteries, ejection charges, all connections made, etc.
  8. Determine if the flight will be "HEADS-UP". A heads up flight includes but not limited to the following: the first flight of a rocket, a rocket that is determined marginal in any way, a multiple-staged rocket and a clustered rocket.
  9. Ensure that the flight data card is completely filled out. Sign the card to certify that you have examined the rocket.
