EOSS #204: NOAA LASP Flight - RESCHEDULED FOR MARCH 7th

EOSS-204 HAS BEEN RESCHEDULED FOR SATURDAY 3/7/2015 WITH SUNDAY 3/8/2015 AS A WEATHER BACKUP DATE. HOPEFULLY THE WEATHER WILL BE COOPERATIVE.

NOAA LASP Temperature Profiler flight

 This is the second EOSS flight for the NOAA/LASP Tropopause Temperature Profiling experiment (EOSS199 was the first).  The goal here is a successful in-flight test of the Fiberoptic Temperature Profiler (FTP) that will reel out a length of optical fiber with an End of Fiber (EOF) dongle.  This 20 gram dongle will be initially housed in a blue foam “garage” on the bottom of the payload that will constrain EOF motion on pre-deployment and initial ascent.  This will simplify the launch of the instrument as the EOF unit will be contained within this “garage”.  Deployment of the EOF will not start until after the payload is above 1000 m AGL to avoid any turbulence associated with the atmospheric boundary layer.  The acceleration rate on the fiber reel will be reduced from what was used in EOSS199 to reduce dynamic load.  Other changes from the EOSS199 test are that there will be a 3-axis accelerometer to record payload motion and a small EOF parachute to slow descent if a fiber break occurs.
