Note: The launch site has been moved to the I-8 Freeman Road Exit (Exit 140) and the fill increased to 140%. NOTAM for these flights is GBN 05/069.
Good Morning,
The Saturday prediction for the ANSR-150 balloon flight with a 140% fill of hydrogen is for a flight of 93 km (58 miles) on a bearing of 079º, landing at 32° 59.741'N, 111° 20.421'W, or 5.6 km (3.5 miles) SE of Florence, Arizona. Burst should occur after 63 minutes with a total flight time of 96 minutes. The assumptions for this prediction are a 3000 gram Kaymont balloon, payload mass of 8.20 kg (17.04 lbs), neck lift of 11.5 kg (25.3 lbs), an ascent rate of 7.64 m/sec (1504 fpm), a burst altitude of 29,595 meters (97,100 feet), descent rate at landing of 6.60 m/sec (1270 fpm) and using the Sondehub Predictor. Google Earth KML, JPG files and a screenshot of the Sondehub.org predictor are attached.
The launch of ANSR-150 is scheduled for today, Saturday, May 11,2024 at 9:00 AM MST (1600 UT), from a launch site near the Freeman Road exit of I-8 (Exit 140) southwest of Maricopa (32° 50.818’N, 112° 19.190’W). The actual launch site will be determined as we get closer to launch day.
The Saturday prediction for the ANSR-151 balloon flight with a 140% fill of hydrogen is for a flight of 92 km (57 miles) on a bearing of 079º, landing at 32° 59.704'N, 111° 21.146'W, or 1.1 km (0.7 mi) west of ANSR-150. Burst should occur after 62 minutes with a total flight time of 95 minutes. The assumptions for this prediction are a 3000 gram Kaymont balloon, payload mass of 8.4 kg (18.4 lbs), neck lift of 11.7 kg (23.3 lbs), an ascent rate of 7.67 m/sec (1509 fpm), a burst altitude of 29473 meters (96,700 feet), descent rate at landing of 6.66 m/sec (1310 fpm) and using the Sondehub Predictor. Google Earth KML, JPG files and a screenshot of the Sondehub.org predictor are attached.
The launch of ANSR-151 is scheduled for today, Saturday, May 11,2024 at 9:30 AM MST (1630 UT), from a launch site near the Freeman Road exit of I-8 (Exit 140) southwest of Maricopa (32° 50.818’N, 112° 19.190’W). The actual launch site will be determined as we get closer to launch day.
