Hello, We are participating in a rocket project, which essentially will reach up to ~130km and fall back to the earth. During both ascent and descent the payload on the rocket will make various measurements. Our team plans to measure some gases, size atmospheric particulates, and observe a biological sample's behavior in the allowed payload area. Since I am a newbie in this type of works, would you please shed some light to the issue? What else we could be measured during the flight? Anyone has experience in this area? I would be happy to see some comments from Russel, because I know he has been posting some stuff from rocket-science related newsgroups. Thank you. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
