Deployment Testing

The full scale booms were tested for deployment. The progression can be seen in the pictures below. The full deployment took one hour and eight minutes. The sail was extended successfully two times.

Full Deployment

A problem was encountered when the sails were extended without an aid to prop them up. A deployment test was started that ended up stalling out in which the booms were not level with the table and started to sag. The sagging was concluded to be the result of the failure. The purpose of this boom is to be deployed in space where there is no gravity to drag the booms down so it is not considered an issue.

Sensor Test

Sail Folding Test

We folded the sails and put them in a vacuum bag.

Code Update

Risk and Problem Tracking

The Risk Management document has been update through out this semester. This semester due to the issues with deployment, not getting the solar sail to deploy is our highest risk. From the last design review the risk is smaller since we got the deployment working but something could still go wrong. Our updated design should help reduce the risk. Other risks

Since we faced some problems with the deployment we updated the problem tracking document which can also be seen below.

Schedule

Plans for next phase

For the next phase, in three weeks, we plan to have all the parts machined. The electronics will be assembled as well. This will allow for full systems tests.
