# Payload

- [Payload Subsystem Report](https://rocketry.gitbook.io/public/previous-projects/bear-force-one-irec-2020-2021/recovery/payload/payload-subsystem-report.md): Attached is an external link to a payload subsystem report written for the 2020 Sounding Rocket Design Challenge, last updated in June 2020.
- [IRIS](https://rocketry.gitbook.io/public/previous-projects/bear-force-one-irec-2020-2021/recovery/payload/iris.md): The IRIS project combines two previous payload concepts, IRIS Legacy and Muons. The collective project can be referred to as IRIS for short.
