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.
All payloads were recovered north of Matheson, CO. Video of the EOSS-255 and 256 Launch videos can be viewed on Youtube here: EOSS-255 Launch ; EOSS-256 Launch

EOSS thanks local landowners for permission to recover the Colorado Space Grant and Ball Intern payloads.
Update Friday 1430: 253 lite and 254 lite payload plans changed to Rev C - swapped COSGC payloads to make exempt weight. Cloud cover forecast is > 5/10ths, so be prepared to split onto lite balloons, and pay attention to which balloon you are on to get you to the right recovery (noted on plans).Launch site has changed to LIMON. There has been heavy rain in the area, and forecasted storms in the afternoon. So be prepared for possible rainy and muddy conditions. Take extra care while driving on the back roads. Hopefully we will recover before the afternoon weather. Note below that our repeater frequency will be 448.450 Mhz. This will be two flights to support the Colorado Space Grant Consortium summer program and the Ball Aerospace BIRST intern program. The nominal configuration will be 2 3000g balloons. However, if cloud coverage precludes non-exempt flights, we will split the payloads and fly 4 1500g balloons to meet exempt requirements. Predictions are located here. In the case of greater than 5/10ths cloud cover, we will split the strings into exempt strings. See below for contingent 'Lite' payload plans.
EOSS-253 will be a 3000g balloon in support of the COSCG Summer DemoSat Program
