(2016): JoSS, Vol. 5, No. 3, pp. 483–511 (Peer-reviewed article available at www.jossonline.com) www.DeepakPublishing.com www. JoSSonline.com A Methodology for CubeSat Mission Selection Luis Zea, Victor Ayerdi, Sergio Argueta, and Antonio Muñoz Universidad del Valle de Guatemala, Guatemala City, Guatemala Abstract Over 400 CubeSats have been launched during the first 13 years of existence of this 10 cm cube-per unit standard. The CubeSat’s flexibility to use commercial-off-the-shelf (COTS) parts and its standardization of in- terfaces have reduced the cost of developing and operating space systems. This is evident by satellite design projects where at least 95 universities and 18 developing countries have been involved. Although most of these initial projects had the sole mission of demonstrating that a space system could be developed and operated in- house, several others had scientific missions on their own. The selection of said mission is not a trivial process, however, as the cost and benefits of different options need to be carefully assessed. To conduct this analysis in a systematic and scholarly fashion, a methodology based on maximizing the benefits while considering program- matic risk and technical feasibility was developed for the current study. Several potential mission categories, which include remote sensing and space-based research, were analyzed for their technical requirements and fea- sibility to be implemented on CubeSats. The methodology helps compare potential missions based on their rele- vance, risk, required resources, and benefits.

  • And Cubesats) Has Come: Analyzing the Numbers
    SSC13-IX-01 The Long-Threatened Flood of University-Class Spacecraft (and CubeSats) Has Come: Analyzing the Numbers Michael Swartwout Saint Louis University 3450 Lindell Boulevard St. Louis, Missouri 63103; (314) 977-8240 [email protected] ABSTRACT We have covered the statistical history of university-class small satellites for nearly a decade, revisiting the numbers every two years. In every previous paper, we have promised/threatened that the number of university-class missions will increase, only to spend the next paper explaining why that flood has not happened – but is definitely going to happen next year. This year, at last, we can break the cycle: the flood of university-class spacecraft has come, in the form of CubeSats; more than 30 are known to be manifested for 2013, with equal (or greater) numbers for 2014. For this paper, we will revise previous studies in two ways: 1) Include the results of the past two years, which will show a continued upward trend in the number of university- class missions, a continued downward trend in the size of the spacecraft, and a not-so-continued dominance of the flagship universities. Have we hit a second turning point in the history of CubeSats, where they switch from novelties to actually-useful missions? (The preliminary answer: maybe.) 2) Expand the study to consider other small spacecraft mission types: specifically the professionally-built CubeSats. We will perform side-by-side comparison of the two. The results will be used in a brave but ultimately naive attempt to predict the next few years in university-class and CubeSat-class flights: numbers, capabilities, and mix of participants.
