EOSS 222/223/224 were launched from the Limon launch site at approximately 0830 on May 21st. EOSS-224 was found after 59 days hidden in a wheat field. See the galleries below for additional information.
EOSS-222 landing site was at 39.65567 N, 103.03233 W
EOSS-223 landing site was at 39.56435 N, 103.136 W
EOSS-224 was found by a local farmer on July 19th while harvesting wheat at 39.58151 N, 103.06175 W
After four weeks of flight delays because of cloud cover, EOSS reconfigured the payloads into three balloons that can be launched through clouds. The balloons were launched from Limon Colorado. All three balloons were launched within seconds of each other. All balloons climbed at various ascent rates and burst at realtively high altitudes. EOSS-222 and EOSS-223 were tracked during descent and retrieved to the northeast. The tracking beacons on EOSS-224 suffered a series of failures and the final beacon failed soon after balloon burst, last reporting an altitude of 102,136 ft. A variety of descent predictions were used to identify serach locations. A week of air and ground searces were not successful in locating the payload string. Landowners were contacted and asked to watch for the payload. The payloads are labeled with "If found" telephone numbers. At this point, EOSS will have to wait for information.
Flight predictions and weather (WX) observations can be linked from this website. When we can, the launch will be at 0700. The intent is to launch the balloons 30 seconds apart. The daily flight path predictions are posted at this website. By clicking on the "GIF" link for the launch site, a map of the predicted flight path is available. This will change daily as the NWS models refine the wind pattern predictions. From Wednesday onward, the predictions are quite accurate. All sorts of flight and weather related links are posted here. Cloud cover at all levels must be less than 50% to fly. If not, we will scale the payload strings in order to fly within the weight restrictions to fly exempt. Sunday May 22nd has been identified as the alternate launch day.
