Red Line Prediction (N0KKZ-3)
Black Line actual flight track (K0ANI)
EOSS-42
LAUNCH DATE: July 16, 2000 (No Rain Date)
LAUNCH TIME: 15:27:44 UTC - 09:27:44 MDT
LAUNCH SITE: The Launch site is at private site and will NOT be open to anyone but the launch site personnel. It is in the vicinity of Byers, Colorado. The prediction details are fudged a little to preserve the privacy of our host but should serve well in planning activities.
PREDICTED vs. ACTUAL TRACK:
Launch Site - Byers ----------------------- Launch Point: 39.7032� lat. -104.2622� long. Ascent Rate: 1112 feet per minute Descent Rate: 1230 feet per minute Altitude: 5400 feet
Predicted Landing Site ----------------------- Landing Point: 39.82� lat. -104.1673� long. Altitude: 5400 feet Flight Time: 111 Minutes Bearing: 32.0� True Range: 9.5 Mi.
Actual Landing Site ----------------------- Landing Point: 39.8355� lat. -104.0545� long. Bearing: 50.3� True Range: 14.3 Mi.
Difference from Predicted to Actual Landing Site -------------------------------------------------- Bearing: 79.8� True Range: 6.1 Mi.
FLIGHT EXPERIMENT:
PROJECT INTEGRATOR: EOSS and Pioneer Astronautics, Dean Spieth "Mars Micro Balloon Probe"
FREQUENCIES:
Attached (above) are first look results of EOSS42 temperatures, as recorded by a HOBO H08-007-02. Not sure of the cold end outside of the box, but temperatures inside the camcorder box appear to be within camcorder's limits. The HOBO worked from launch to touchdown! We could have acquired a HOBO T/C type T calibrated with NIST certs, but we decided to go the cheap route using the thermistor external on this flight as well as the HOBO's internal sensors.
Indeed, the camcorder worked thru burst at 80,000 feet, and about 6 seconds thereafter, when shock/vibration probably turned off the mechanisms. The battery still indicated 2 hours left after recovery, but the camcorder was very damp. It's a good picture, lots of banging about - we need to bolt our packages together and forget the big black balloon flag. The "flag" still shows lots of turbulence and crosswind even at 80,000 feet, so even though it would be good to qual the nichrome cutter on Chuck's flight (if he'll let us), I think we need over 100,000 feet to get a good Mars balloon experiment.
Sincerely, Dean Spieth
Jack Crabtree [AA0P] was at our launch and took several pictures. Here are a couple.
Inflation underway
Mike, W5VSI, ponders the telemetry
Notes:
Shuttle Generated Automatic Position Reporting System (APRS):
While intermittent, the Shuttle provided good GPS data through most of the flight.
