EOSS-317 at 98,218 feet. Photographs before and at burst by Tiffany Jewell
EOSS-317 was lauched as a 3000g balloon from Windsor, Colorado at 0730 MDT on October 30, 2021, carrying eight payloads from Metro State University's Intro to Space program. The balloon reached an altitude of 98,304 Ft and landed at 9:37 MDT North of Masters, Colorado.
Payloads developed by student teams from Metro State University's Introduction to Space classes
One 3000g balloon or two 1500g balloons. Flight predictions can be found here. Live flight tracking the day of the flight is here.
If cloudcover exceeds 5/10ths, the balloon will be split into two exempt 1500g balloons:

EOSS Preflight Net @ 7 PM Mountain Time preceding night:
• 449.225 MHz (-5 MHz Offset, 141.3 Hz CTCSS) Rocky Mountain Ham Radio (RMHAM) Repeater and EchoLink *CANONCTY* conference and the Fun Machine linked system
• 146.940 MHz (-600 KHz Offset, 103.5 Hz CTCSS) Rocky Mountain Radio League (RMRL) Repeater if the RMHAM machine is down
• 146.640 MHz (-600 KHz Offset, 100.0 Hz CTCSS) Denver Radio League (DRL) Repeater will serve as a backup to the backup repeater
Launch Site:
• 446.050 MHz Simplex
(Note that some radios assume these are repeater frequencies and attempt to put a 5 MHz offset in the transmit frequency automatically)
Track & Recovery Operations:
Repeaters:
• 449.450 MHz (-5 MHz Offset, 103.5 Hz Tone) RMRL repeater (Assuming we are flying out of Windsor).
• 448.450 MHz (-5 MHz Offset, 100.0 Hz Tone) PPFMA repeater (Assuming we are flying out of Deer Trail).
Simplex Frequencies:
• 446.100 MHz Balloon #1 Field Simplex
• 446.150 MHz Balloon #2 Field Simplex
• 446.200 MHz Balloon #3 Field Simplex
• 446.275 MHz Car to Car drive out Simplex
(Note that some radios assume these are repeater frequencies and attempt to put a 5 MHz offset in the transmit frequency automatically)
Legacy 2M Simplex Frequency (not generally used due to desense/interference issues with the 2M APRS packets)
• 146.550 MHz Simplex
