-====== HelioSS 1 ======
+====== Project HelioSS ======
+HelioSS is a project to carry experiments from [[http://www.sponneschool.northants.sch.uk|Sponne School Technology College]] in Towcester to the edge of space.
-HelioSS 1 was a launch carrying experiments from Sponne School in Towcester. It was launched from the CUSF site at Churchill College but not recovered due to loss of position data during ascent.
+====== HelioSS 1 ======
-====== Flight computer ======
+[[launch:300610helioss|HelioSS 1]] was the first flight. It was launched from the CUSF site at Churchill College and found a week later by a farmer. More information can be found on the mission page.
-The flight computer is based on a LPC-H2214 ARM development board from [[http://www.olimex.com|Olimex]]. It also includes:
-  * FSA03 uBlox GPS receiver
-  * Radiometrix NTX-2 radio transmitter
-  * Several TC77 one-wire temperature sensors
-A 12 bit A/D converter is used to provide the signal to the NTX-2, allowing fine frequency adjustment. By adding a temperature sensor mounted directly to the NTX-2, we hope to minimise the usual frequency shift observed as the NTX-2 cools.
-====== Payload ======
+====== HelioSS 2 ======
-The payload includes:
+HelioSS 2 is currently under development.
-   * Two cameras (a Canon A480 and a Canon A560), both running CHDK
-   * A thermal experiment measuring the temperature of four targets, each painted a different colour
-   * An experiment to demonstrate Boyle's Law using party balloons
-   * A radiation experiment using a medical radiation dosimetry badge
-   * An experiment to observe the effects of high altitude exposure on Brine Shrimps
