Due to weather considerations the flight has shifted to SUNDAY Oct 10th. Payload plans have been updated. 10/8/21: Grid changes, added trackers.10/9/21 0900 Revision C payload plans posted to reflect appropriate weights in all places. Rev C is a WEIGHT ONLY update. One 1500g balloon carrying NDIA-sponsored STEM exteriments from multiple schools and one 3000g balloon carrying three intern-developed payloads from Northrup Grumman Space Systems. Flight predictions for these flights can be seen here. Flight tracking the day of the flight can be found here.
A single 1500 gram balloon with NDIA payloads.
