Day 7, Camera integration and Rexus test countdown

Today we integrated the camera into the rocket. This means it is attached to the rocket and all connectors are plugged in. Next step is to implement the camera software into the flight computer software so that the MCU can turn the camera on. This is almost finished. The camera can look to the outside via a very small window (6 mm) in the nosecone. Furthermore the ETAG (Esrange Tracking And GPS) is prepared to be integrated into our rocket. This device has been developed by Esrange and will transmit the GPS location of the rocket after landing. Hopefully it can also get a lock during the flight so that it can provide data about the flight trajectory as well.

This evening the test countdown was held for the Rexus 6. This means that it will probably be launched tomorrow. After Rexus 6, the Rexus 5 rocket can be brought to the launch pad, leaving the assembly area empty. As soon as this happens we can start assembling the Stratos rocket. So the best case scenario is as follows: Tuesday Rexus 6 launch, Wednesday Rexus 5 goes to launch pad, Thursday start assembling Stratos Rocket, Friday launch Stratos rocket. This is the best case scenario and can be delayed because of the weather, delays in the Rexus campaign and interference with the ongoing balloon campaign.

Last but not least: if you have a question about something in this blog feel free to leave a comment.

To keep the ETAG in one piece during the flights (with shocks of 45G) it is necessary to reinforce some parts with epoxy glue.

To connect the ETAG to our flightcomputer it is necessary to solder some wires, diodes and a resistor on it. Eric is checking his solder works here.

Because of safety it is prohibited to have powered on cellphone in the launching area. If you dont do this, this is the consequence

    Nice site and we follow your adventures almost minute by minute.
    We hope that you will be able to launch next Friday.
    How many days a margin do you have?

    Dear Stratos crew,
    It is great to be able to read and see daily what you are up to. We are keeping fingers crossed that you will be able to launch this Friday and beat the record, good luck!
