(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. -
A Statistical and Personal History of University-Class Satellites
SSC18-WKVIII-03 Reliving 24 Years in the Next 12 Minutes: A Statistical and Personal History of University-Class Satellites Michael Swartwout Saint Louis University 3450 Lindell Blvd, St. Louis, MO 63103; 314-977-8214 [email protected] ABSTRACT In 2018, university-class satellites -- spacecraft built by university students for the express purpose of student training -- are widely accepted as a means to recruit undergraduate students into the space workforce, train them effectively before graduation and retain them in the field after graduation. Hundreds of undergraduates at dozens of schools around the world have directly contributed to missions that operated on-orbit. The spacecraft themselves are capable of performance research-grade science or demonstrate new enabling technologies. This was not always the case. For the first forty years of spaceflight, there were exceedingly few university-class missions; those that flew were expensive, marginally-performing and had modest success rates. What changed? Why are university-class missions now commonplace? And, with respect to on-orbit success, are they as good (or as bad) as rumor and hearsay make them out to be? In this paper and all-too-brief talk, the history of university-class spacecraft will be discussed, with an emphasis on the types of missions and their success rates. Beginning in 1994 (the author's first time attending this conference, as a wide-eyed student) and reaching through to 2018 (the author's 21st, now as a world-weary professor) a statistical and anecdotal review of -
The First One Hundred Cubesats: a Statistical Look
Swartwout, M. (2013): JoSS, Vol. 2, No. 2, pp. 213-233 (Peer-reviewed Article available at www.jossonline.com) www.DeepakPublishing.com www.JoSSonline.com The First One Hundred CubeSats: A Statistical Look Michael Swartwout Parks College of Engineering, Aviation and Technology, Saint Louis University, St. Louis, Missouri, USA Abstract The concept of CubeSats was publicly proposed in 2000, with the first CubeSats launched in 2003. By the end of 2012, more than one hundred CubeSats have been launched, and 80 more are manifested for launches in 2013, with at least that many expected in 2014. Ten years ago, CubeSats were routinely dismissed by industry profes- sionals as being too small to be worth flying; now, NASA is the majority launch broker, and a significant share of the manifests are filled by U.S. DoD-sponsored, industry-built CubeSat missions. How did initial perceptions of CubeSats evolve to this state? Are CubeSats toys, tools, or merely another source of orbital debris? With so many CubeSats now in orbit, it is now possible to make a data-based assessment of these missions. Us- ing data collected from a variety of sources, this study evaluates the on-orbit performance of CubeSats. The history of CubeSat missions is reviewed, with the missions classified according to size, origin, mission life, and on-orbit performance. It is shown that several correctable design/implementation errors plague the university side of Cube- Sat missions, and that the P-POD launch container, not the CubeSat specification, is the true enabling technology for this class of mission.

WORLD SPACECRAFT DIGEST by Jos Heyman 1998 Version: 10 July 2016 © Copyright Jos Heyman 1998 001A (25131) Name: Lunar Prospector Country: USA Launch date: 7 January 1998 Re-entry: 31 July 1999 Launch site: Cape Canaveral Launch vehicle: Athena 2 Orbit: 99 x 100 km, inclination: 90.1 ° The Lunar Prospector was the third mission in NASA's Discovery series of spacecraft and was built by Lockheed Martin. The mission objective was to place the spacecraft in a lunar orbit from which it spend a year mapping the surface of the Moon whilst at the same time looking for reservoirs of water which might be in the polar caps. The 126 kg spacecraft carried a series of instruments which evolved from Apollo instrumentation from the seventies: 1. the Gamma Ray Spectrometer (GSR) which provided global maps of the elemental composition of the surface layer of the Moon; 2. the Alpha Particle Spectrometer (APS) to detect radon outgassing on the lunar surface; 3. the Neutron Spectrometer (NS) to detect water ice; 4. the Electron Reflectometer (ER) to map the lunar magnetic fields; 5. the Magnetometer (MAG), another instrument to map the lunar magnetic fields; 6. the Doppler Gravity Experiment (DGE) to determine the lunar gravity field. Also carried was a small container with the ashes of Eugene Shoemaker, a famous discoverer of comets who had passed away in 1997. This container was designated as Celestis-2 and the payload was also known as Luna 1 flight. The spacecraft did not carry a control computer, instead it was fully controlled by a team on Earth. -
