-Parity ​: None + 
-Stop bits: 2 +==== Mission Profile ==== 
-8bits+ 
 +High altitude (meteorological) balloon flight with 3 payloads. One Raspberry Pi, one custom pico PCB and tardigrades. Antenna has been reverted back to the stubby with dish due to poor performance from the co-linear dipole
 + 
 +==== Mission Objectives ==== 
 + 
 +Primary 
 + 
 +  * Successful launch and recovery of the pico using a high altitude balloon 
 +  * Test new antenna of RPi with stabilising disk 
 +  * Test new payload shape 
 +  * Receive telemetry from Pico at over 10km 
 + 
 +Secondary 
 + 
 +  * To advance our ability to design, manufacture and fly hardware 
 +  * To provide useful data and experience for future balloon flights and other missions; e.g. telemetry, tracking 
 +  * To provide reference and publicity material for outreach activity 
 +  * To record biological payloads before and after flight 
 +  * Test wide angle camera with standalone battery 
 +  * Revieve LoRa transmission from Pico 
 + 
 +==== Flight Plan ====

 +^  Performance Sensors ​ |Unknown ​ | 
 +^  Additional Equipment |Camera [standalone] drawing power from separate cells  | 
 +^  ​:::  |Tardigrade container with [[https://​www.sciento.co.uk/​catalog/​tardigrades/​Z160--Dactylobiotus%20dispar|Tardigrades]] | 
 + 
 +Pico Package [[pico:​electronics|Pico-EP-M1]] 
 +^  Core  |Pico PCB| 
 +^  :::  |Battery| 
 + 
 +388g hab payload 
 +35g pico 
 + 
 +0g parachute 
 + 
 +==== Tracking & Communication ==== 
 + 
 +Direct tracking will be achieved using Tracking Kit [[tracking:​TK-M2]]. This will be used for tracking on launch and landing. 
 + 
 +Indirect flight tracking will be achieved using HAB community online resources. 
 + 
 +We also be using LoRa to communicate with the Pico, this currently is being tracked by our own equipment, which is another PicoPCB.

 +==== Mission Outcome ==== 
 +**Summary** 
 +The mission was regarded as a failure. We did not achieve our objectives and we lost the pico payload. 
 +The balloon was released during windy conditions. There was consensus that it was safe enough to launch despite protests. The balloon traced a large sideways path and it eventually got caught in a telephone line. The line was cut and the balloon was let go with the pico. The main hab payload was left on the telephone line and was collected later by a BT engineer. 
 + 
 +**Discussion** 
 +We agreed to make sure that we do not launch if the conditions are windy, even with some light wind.
