EOSS-275 and 276 were launched from the Limon Softball fields launch site on July 21st, 2018 carrying payloads for the Ball Intern Remote Sensing Team.
EOSS-275 reached an altitude of 94,841 ft and the payloads were recovered at 39.262, -103.583
EOSS-276 reached an altitude of 96,714 ft and the payloads were recovered at 39.256, -103.608
The payloads were recovered approximately 3 miles southeast of Genoa, Colorado.
Update 7/20/18 1800: Rev B for 275H and 275L, Rev C for 276L uploaded. Only changes were to the weight charts to upload new lift factors.Update 7/20/18 0930. Since the launch site will be Limon, T&R repeater will be the PPFMA 448.450 machine. Also testing use of the Rocky Mountain Ham DMR system. See below for details.Update 7/18/18 2000. Rev B posted for EOSS-276 Lite, updated AE0SS-13 timeslotting to :10 and :40 One 3000g balloon or possibly 2 1500g carrying payloads from Ball Aerospace's BIRST internship program
This will be a single 3000g balloon for the BIRST Program
