We at the Santa barbara Hackerspace have been involved in over a dozen weather balloon launches. We have had a lot of fun with these launches and learned a lot, but found some issues with existing means of tracking. Most of the commercially available APRS trackers are closed source, large,...
Balloon-borne experimentWe experimentally determined the suitable conditions of temperature and air pressure for measuring charge and mass compositions of heavy cosmic rays using CR-39 track detectors during long-duration, high-altitude balloon flights. The experiments were carried out utilizing Fe ion ...
and high altitude aerial imaging. In the last two decades, cameras have gotten a lot cheaper, they've gotten smaller, they've gotten lighter A lot of the NYPD camera systems have 4K resolution, night vision capabilities, 360 monitoring, ...
I've tracked planets with my dob...but I don't recommend it. I've tracked them with my 81mm too, it's much easier. Was watching a weather balloon with the dob at outreach setup one time and saw it burst apart and release a lot of sparkly stuff...was kinda cool. JIMZ7, faac...
This temperature effect may cause errors in cosmic ray composition experiments employing detector arrays exposed by means of high altitude balloon flights or earth orbiting spacecraft with passive temperature control. Outline results are presented for a series of exposures to high energy Fe beams at ...
This technique was applied to CR-39 detectors exposed to fast neutrons and those flown on a high altitude balloon in order to evaluate the proton response. An improvement by using multi-step etching was also carried out. It was found that not only a single set of the etch rate ratio and...
