Background
ASCEND! (Aerospace STEM Challenges to Educate New Discoverers) is an Arizona Space Grant Consortium statewide workforce development program that gives students hands-on experience with the full design-build-fly-operate-analyze cycle of a space mission.
Student teams from colleges and universities across Arizona design and build scientific payloads that fly aboard high-altitude weather balloons, reaching altitudes of approximately 100,000 feet. Students collect atmospheric data, capture images of Earth, and analyze their results to study phenomena such as cloud structure, surface features, and the curvature of the Earth.
Participating institutions include The University of Arizona, Arizona State University, Embry-Riddle Aeronautical University, Arizona Western College, Glendale Community College, Pima Community College, Central Arizona College, Phoenix College, and Casa Grande Union High School. *We are unable to support additional teams at this time.
ASCEND! complements classroom learning with real-world, hands-on mission experience, giving students the opportunity to take a project from initial design through flight, operations, and data analysis.
Overview: ASCEND Payload Design
Our Flight Partners
AZSGC partners with Arizona Near Space Research (ANSR) for our flight operations. ANSR is a 501(c)(3) nonprofit organization engaging students in science, technology, engineering, and mathematics education through hands-on learning with amateur radio and high-altitude ballooning. Since 2001, ANSR has proudly supported over 150 balloon launch opportunities, helping bring real-world learning opportunities to students across the state.
Payload Design Specifications
The ANSR Payload Design Specification (PDS) outlines the standards and guidelines all payloads must meet to safely and successfully integrate into our launch systems. It covers topics such as payload size, weight limits, power systems, communication interfaces, and flight safety requirements.
By following these requirements, you help ensure your project is compatible with ANSR’s flight hardware, recovery operations, and FAA regulations.
PDS Waiver Submission Form
All teams are required to review and follow the payload design specifications. If your design includes any features that extend beyond these specifications, you’ll need to request a waiver for approval. Fall 2026 waiver submissions are due no later than October 16, 2026.

| Date | ASCEND! FLT# | ANSR Flt# | Launch site | Altitude (ft) | Notes |
|---|---|---|---|---|---|
| 03/28/2026 | 62 | 162 | Intersection of AZ-347 and HWY-84 | 82,398 | Very windy day and difficult recovery near the SE corner of the San Tan Park and Gila Reservation line. |
| 03/28/2026 | 61 | 161 | Intersection of AZ-347 and HWY-84 | 65,553 | Very windy day resulted in balloon bursting earlier than expected. |
| 12/06/2025 | 60 | 158 | UA Maricopa Ag Center | 101,260 | Rescheduled launch from Nov. 22nd due to weather. Easy launch and recovery! |
| 12/06/2025 | 59 | 157 | UA Maricopa Ag Center | 101,020 | Rescheduled launch from Nov. 22nd due to weather. Easy launch and recovery! |
| 03/28/2025 | 58 | 156 | Freeman Road exit, Gila Bend | 87,770 | Balloon 2 took 2 hours and 26 mins to achieve this altitude. |
| 03/28/2025 | 57 | 155 | Freeman Road exit, Gila Bend | 94,620 | |
| 11/23/2024 | 56 | 154 | Freeman Road exit, Gila Bend | 102,000 | |
| 11/23/2024 | 55 | 153 | Freeman Road exit, Gila Bend | 98,000 | |
| 5/11/2024 | 54 | 152 | Freeman Road exit, Gila Bend | 102,964 | Rescheduled launch from March 23, 2024. |
| 5/11/2024 | 53 | 151 | Freeman Road exit, Gila Bend | 99,000 | Rescheduled launch from March 23, 2024. |
| 11/18/2023 | 52 | 148 | Near AZ60 & I-10 Interchange | 96,906 | |
| 11/18/2023 | 51 | 147 | Near AZ60 & I-10 Interchange | 103,988 | |
| 04/01/2023 | 50 | 144 | Near AZ60 & I-10 Interchange | Upon filling balloon, ANSR noticed there was a hole in it so we had to fill a new balloon causing a slight delay. Balloon landed near Aguila, AZ in difficult area. ANSR had to retrieve the payloads and then distribute to the ASCEND teams. | |
| 04/01/2023 | 49 | 143 | Near AZ60 & I-10 Interchange | Balloon landed near Aguila, AZ in difficult area and had to be retrieved by ANSR to be handed off to the ASCEND student teams. | |
| 11/19/2022 | 48 | 141 | UA Maricopa Agricultural Center | 102,272 | Difficult retrieval; payloads landed quite a ways off road and required a hike to retrieve the payloads from a desert wash. |
| 11/19/2022 | 47 | 140 | UA Maricopa Agricultural Center | 100,420 | Upon burst, it appears that pieces of the balloon wrapped around the parachute and prevented it from fully opening. Quick descent and impact at ~55 mph. Payloads felt the impact! |
| 4/02/2022 | 46 | 138 | Freeman Road exit, Gila Bend | 97,000 | |
| 4/02/2022 | 45 | 137 | Freeman Road exit, Gila Bend | 91,000 | |
| 11/20/2021 | 44 | 135 | AZ-85, approx. 12mi S. of Gila Bend | 102,303 | ANSR flight-135 climbed at a faster rate than ANSR flight-134. ADSB-B for 135 worked throughout the flight. |
| 11/20/2021 | 43 | 134 | AZ-85, approx. 12mi S. of Gila Bend | 103,670 | The landing site was more than 20mi east of the predicted area. The ADS-B for ANSR-134 worked shortly after liftoff but then stopped working. Upon recovery, it was discovered that the battery in the case had shifted during flight and pulled the power pole connector apart. |
