RocketSat 11

Partnered with a local Colorado company called ROCCOR to build a payload that imaged and analyzed the deployment of a composite boom. Our payload successfully deployed the boom and delivered a detailed characterization of the deployment to ROCCOR.

(Rapid EXpandable-Boom)

Payload consisted of a 1.5m composite boom manufacured by ROCCOR, two GoPro Hero 3+ Blacks (one for high resolution, one for high framerate), a low resolution camera to downlink images, and an environmental suite.

Launch

Launched from Wallops Flight Facility in Virginia on a Terrier Improved Malemute Rocket.

Payload post launch

Boom was ejected in space to ensure that the rocket could respin correctly and the boom wouldn't affect other payloads

3D position of boom during deployment

Left and right corners of boom were clicked on in GUI to characterize position over time. Built a 3D model of the tip positions as a function of depth to demonstrate lateral instability during deployment.

Depth of boom over time

Entire deployment occured in under 0.4 seconds and accelerated as the boom unraveled.

Deployment video
(in space!)

The kick-off springs, which ensured the deployment of the boom, can be seen floating in front of the boom.

Boom ejection

Rocket respin and reentry occured shortly after.
