EOSS-269, 270, 271, 272 launched on 4/7/18 carrying CU Gateway to Space and COSGC colleges payloads.  Balloons were launched from Eaton, Colorado and all payloads were recovered 130-140 miles downrange near Vona, Colorado.

EOSS-269 reached an altitude of 97,067 ft and landed at 39.97019, -103.13995

EOSS-270 reached an altitude of 94,542 ft and landed at 39.40891, -102.8575

EOSS-271 reached an altitude of 95,828 ft and landed at 39.37105, -102.7435

EOSS-272 reached an altitude of 90,535 ft and landed at 39.27356, -102.65756

EOSS-268 with seven Colorado Space Grant Consortium payloads weighting 13.9 pounds, two GPS-equipped radio beacons, a fast release mechanism under test, and a 9 ft. Rocketman parachute were launched on a 3000 gram balloon from the Deer Trail, CO launch site (N39° 36.72', W104° 2.52') at an elevation of 5,538 feet at 7:16 AM MDT on Mar. 17, 2018.  The last packet received before balloon burst was at 8:59 AM at an altitude of 100,211 ft. after an ascent averaging 919 ft./min.  The maximum recorded speed was 77 mph at 9:09 AM at an altitude of 43,564 ft.

Thanks to everyone that supported the EOSS-267 flight yesterday. It was a resounding success in several ways.  We shook the cobwebs off of our knowhow and  tracking stations, we successfully qualified several new payloads, and we had some new members join us in the chase!  We had several University of Colorado CBASE students join us for the launch and recovery to help hone their skills for assisting in planning, launch, and recovery later this year.

EOSS-265 with ten CU Gateway to Space Class payloads weighing 18.39 pounds, two GPS-equipped beacons, an Iridium tracker and a ten-foot parachute were launched on a 3000g balloon from the Windsor, CO launch site (N40° 30.29', W103° 48.58') at an elevation of 4969 feet at 

EOSS-264 was flown sucessfully as a single 3000g balloon under FAA 14 CFR Part 101 rules.The balloon launched at 7:34am and reached an altitude of 107,162 feet. It landed at 40.56792, -102.73136, a distance of 127 miles near Haxtun, Colorado.The mileage link for EOSS members is https://goo.gl/forms/7WzkhIvvhhNIucmB3Drone video of the recovery is posted on youtube: https://www.youtube.com/watch?v=85AUGQyZH14jim was here

EOSS-262 with the NSSTI payloads was launched on a 1500g balloon from the Deer Trail, CO high school football field (N 39 ° 36.81', W103° 28.28') at an elevation of 5224 feet.

EOSS-260 was launched the Camp Guersey North Training area (N 42 ° 22.629', W104° 44.834') at an elevation of 5014 ft. at 10:33 AM MDT. The balloon burst at 12:14:45 MDT at an altitude of 96,459 ft. after an ascent averaging 901 ft./min. The parachute and flight string touched down at N 42° 24.683', W 103° 54.316' at 12:50 PM at an elevation of 4699 ft. after a flight of 2 hours 17 minutes. Horizontal touchdown speed was 21 mph. The straight line distance between launch and touchdown was 43.0 miles along the ground. After touchdown the wind pushed parachute and flight string about 59 ft.

EOSS-261 was launched the Camp Guersey North Training area (N 42 ° 22.575', W104° 44.835') at an elevation of 5178 ft. at 10:50 AM MDT. The balloon burst at 12:59:30 MDT at an altitude of 95,688 ft. after an ascent averaging 702 ft./min. The parachute and flight string touched down at N 42° 28.775', W 103° 33.448' at 13:39 PM at an elevation of 4823 ft. after a flight of 2 hours 49 minutes. The touchdown horizontal speed was 18 mph. The straight line distance between launch and touchdown was 61.2 miles along the ground. After touchdown the wind pushed the parachute and flight string another 597 feet along the ground. The parachute and flight string were recovered at N 42° 28.686', W 103° 33.504' at an elevation of 4525 ft.

All three flights were very successful.

EOSS-253, 254, 255, and 256 were launched in rapid succession starting at 0700 from the Limon Softball fields launch site on July 15, 2017. All were 1500g exempt balloons.
