The BalloonSat program at New Mexico State University (NMSU) aims to provide more students with mission opportunities in a predictable manner. Building on a successful test flight with NASA, the program envisions flying multiple university payloads on a common carrier, each under 50 kg. This initiative seeks to allow universities to engage with nanosatellite technology and near-space conditions without the complexities of traditional satellite launches. The program requires funding, infrastructure development, and collaboration with NASA and other entities for its success.

  1. Common BalloonSat Payload Program Stephen Horan New Mexico State University

  2. Topics • Background • Program Vision • Differences with HASP • Next Steps BalloonSats

  3. Background • NMSU participated in the test flight of a NASA 34 Mft3 balloon on May 31/June 1, 2008. • Total flight was over 24 hours and maximum altitude was 120,000 feet • NMSU flew the basic science experiment and many of the subsystems for the NMSUSat that was developed under the University Nanosatellite Program. • Also tested groundstation operations from Fort Sumner, NM, Holbrook, AZ, and the NMSU campus over the Internet. BalloonSats

  4. Background • How was this arranged? • NMSU is the M&O contractor for the CSBF, so we used connections to make the link-up • What were the restrictions? • Be ready to fly without major impacts to NASA’s mission • Could not dictate flight date, moon conditions (critical for us), flight altitude, or flight duration (NASA’s 24-hour minimum flight objective at 120,000 feet was fine for us so this was not a problem) • Must be ready for all pre-flight tests on demand BalloonSats

  5. Background • What infrastructure was required? • We requested our own C&T link so they were not allowed to interfere with NASA’s operational support; we used VHF amateur frequencies and a low-power transmitter • We requested space for payload prep and groundstation staging both at Fort Sumner and Holbrook. This was not a major issue for CSBF. • We requested batteries for the payload which is a normal part of CSBF accommodations for experiments • We requested CSBF power-on/power-off commanding which is normal experimenter support BalloonSats

  10. Program Vision • Ultimate goal is to give more students mission opportunities in a predictable manner • Can we fly 4 to 6 similar university missions on a common carrier? • Each payload would be < 50 kg in mass • Provide common mechanical, electrical, and communications interfaces • Batteries and/or user-supplied solar panels • IP-based packet communications on the carrier and from the groundstation to the university POC BalloonSats

  11. Program Vision • Each team would fly standalone missions • Who might be interested in these flights? • Nanosat teams wishing to try out satellite electronics and groundstations in near-space conditions • Universities wishing to prove they can be competitive with a cubesat/nanosat program • Universities wishing to have a near-space experience without the uncertainties of launch dates, ITAR problems, or just the hassles of a satellite launch program. BalloonSats

  12. Program Vision • Teams selected through competition for slots on annual or biannual basis (TBD) • There would need to develop the common infrastructure • Hopefully NASA and/or Air Force would fund this • Negotiate with NASA for the balloons and the CSBF support crew • There would need to be funding for infrastructure support crew to maintain the hardware and interface with the CSBF crew. User fees? BalloonSats

  14. Differences with HASP • The LA Space Grant runs the HASP program for small experiments and a few 20-kg class payloads. • So what is the difference? • No sensor experiments here, only full payloads • Each payload will need to have full normal operations support from their POC; flight support will do nothing other than power up/power down commands • POC may be located at home school and communicate with NASA facilities over Internet BalloonSats

  15. Next Steps • Determine if there is a need for this type of program and, if so, who wants to join in. • If we go forward, we will need to find sponsors to at least build and maintain the infrastructure. • Develop necessary interface control documents • Determine if there is a user fee or try to find sponsorship to underwrite launch costs • Determine methodology for payload selection and reporting results BalloonSats
