Welcome to the Sirius Rocketry Online Store!

We're Back!

Note that I have been progressing with a major upgrade and refresh of the online store. I am working on some new features and other enhancements and may have to go down from time to time for testing. Some parts of the store may look different. Shipping of orders may be delayed for a short while while I dedicate many long hours time to this refresh. Thanks for your patience and understanding!   - David

New! Dog Star Rockets now available!

2026 Shipping Days

Sirius Rocketry will be shipping orders Monday through Thursday through the seasons. Offices and shipping closed Friday - Sunday. You may continue to place orders as normal Friday through the weekend and we will process and ship those in the order received the following Monday. This leaves us with some additional free time for product production and a little rest time for ourselves after 26 years in business! 

NOTE: No High Power rocket motor orders will be shipped unless we have the proper NAR/TRIPOLI membership and/or certification documentation and if we do not receive it in a reasonable amount of time we will cancel your order and deduct our administrative costs.  We will no longer chase you down for this information and request it multiple times anymore as it is a requirement of your membership in NAR/TRIPOLI to provide this information to retailers in order to order high power. High Power motor order requirements and information are here:  https://www.siriusrocketry.biz/ishop/pages/high-power-motors-and-reload-kits-ordering-info-16.html 

Due to hazardous shipping regulations, ALL Engine/Motor Sales are final and cannot be returned! Make sure you order the exact motors you want!
