**EMI testing of the electrical system**

A couple of weeks ago we had the oppertunity to test run our electronics inside an EMI chamber to see if we are EMC compliant. The pictures below are from inside the EMI chamber.

The EMC test gave us alot of insight into which frequency bands we are disturbing and how to proceed with implementing shielding to our module.

**Integration progress**

We are now in the middle of integrating the electrical system with the rest of our hardware and software. The results have been very exciting! We are now at the stage where we are verifying new requirements every day and progress has been very smooth. We did have some issues with the electrical system, but thanks to Aislers quick production and delivery, we were able to fix up those issues very efficiently! Below are some pictures of the current state of the module.

**Drill testing**

Earlier this week we also had our first successful drilling test. We started up the module and let it run until it had extracted a small core from a prepared asteroid simulant sample. This was a huge milestone achieved for the team as we now have it confirmed that our designs will work to acomplish the most important functional requirements. The pictures below show the drill as it had moved partly into the sample (we know its hard to see but there was a lack of pictures to show).
