Three 1500g Lite balloons were launched from Deer Trail on Saturday, December 6, 2025. The upper level winds were higher than expected and the real-time landing predictions were putting the balloons across the state line in Kansas. Ultimately the balloons did land in Colorado and were easily retrieved once landowner permission was obtained. The balloons performed as follows:

Two 3,000g balloons were successfully launched on November 8, 2025, a breezy Saturday morning from Wiggins High School. The first balloon 386 launched at 6:47am reaching an altitude of over 100,000ft. The second balloon burst upon filling, and a backup balloon was successfully filled with 387 being launched after 7 am reaching an altitude of over 80,000'.
On Sunday, November 2, 2025, two 3000g balloons were launched from Wiggins High School, carrying fourteen Metro State University Intro2Space payloads. Because of an excessive long prediction for Saturday, the flight was delayed until Sunday. The weather was cool but managable. The balloons flew as follows:
Monitor all three EOSS pico balloons here. Unfortunately, as of 11/17, we have not heard from EOSSP-2 or EOSSP-4 for 5 days and 3 days, respectively. The fact that they were relatively close together and floating at 43kft suggests that they might have encountered the same weather system and were taken down. But, EOSSP-3 disappeared for seven days, then reappeared, so there's always hope.
EOSS-383 was launched at 7:25 a.m.on Saturday, October 17, 2025 from the Limon Softball Complex and achieved an altitude of 96,548 feet before cutdown and release of the parachute which brought the payload safely to rest at 09:48 AM in far eastern Cheyenne County near the intersection of CO State Hwy 385 and County Road Y (38.9233333,-102.3451667).
This isn't really a Recap, because the pico balloon is still flying, as of November 29, 2025 (day 72) it has made five circumnavigations of the world (see map in Charts & Data).
This will henceforth be known as the EOSS 381/382 Fog, Battery, Brakes, Fork Flights. Two 1500g balloons were launched from the Limon Soft Ball Fields on Saturday, August 2, 2025.

EOSS FLIGHT 380 a 3000g balloon was launched at 7:10am Saturdat July 26, 2025 from Genoa Campground. It carried two payloads designed and built by BAE Systems Interns. Picture perfect launch with a little dance done by the last two payload handlers. They followed instruction perfectly. Great Job. The balloon birst at 98,184ft, and landed at 39.59657, -103.46211, or County Rd 2 and County Road P. This might be the first time the land owners phone number was on the corner post of the field! It warned about hunting without written permission and gave two numbers.
One 1500g balloon was launched on Tuesday, June 17, 2025 from VFW Post 7945, Thornton, CO and reported a maximum altitude of 96,874 ft. A successful recovery was achieved in north Adams County at 40.03883, -104.3635. A detailed summary of the flight will follow soon.
GPSL launch scheduled for June 14, 2025 at 7:30am in Buhler KS was put on a weather hold. We sat in the hotel breakfast area watching the rain falling sidewise because of high winds and looking for tornadoes. We heard from Zack that the rain would stop and the skies would clear for an 1:00 pm launch. We headed to Buhler around 11:30am to set up.EOSS launched one 2000g balloon with our scheduled payloads and added two additional beacons with Horus binary. With help from other teams our balloon was up and away. We stayed at the launch site and helped other teams launch.
