 ====== ALIEN - ALtitude Imaging Entering Near-space ======
-This is a project run by GCSE students from Reading School, in Reading, UK. The objective of our first flight (ALIEN-1) is to reach an altitude of approximately 30km (~100,000ft) and take photographs of the Earth/space horizon. We will also include two environmental temperature sensors: one external, one internal. Communication will be by one-way radio downlink, GPS telemetry only.

-===== Launch =====
-We plan on launching the balloon sometime in <del>May</del> <del>June</del> <del>July</del> <del>August</del> this decade. Launch site will most probably be Cambridge University (with help from the spaceflight club there). However, all decisions are obviously dependent on the weather.
