[ Air Force/Staff Sgt. Andrew Satran]How do you start a CubeSat project?

7 As popular as cubesats have become, it s surprising how little information is out there to help someone just enter-ing the field. That s why this document was created to lay out everything you need to take a great CubeSat idea and make it into an actual spacecraft that is launched into orbit. If you ve been involved in the CubeSat world for a while, this guide will be a good reference for anything on which you might need a refresher. However, this guide is written for First-Time CubeSat developers, and especially for cubesats being developed at educational institutions. So, if this is your first foray into cubesats , you ll want to read through carefully to get an idea of the scope and the amount of work this project will we get to the nitty-gritty, let s start with a little background. cubesats began as a collaborative effort in 1999 between Jordi Puig-Suari, a professor at California Polytechnic State University (Cal Poly), and Bob Twiggs, a professor at Stanford University s Space Systems Development Laboratory (SSDL).

8 The original intent of the project was to provide affordable access to space for the university sci-ence community, and it has successfully done so. Thanks to cubesats , many major universities now have a space program. But it s not just big universities; smaller universi-ties, high schools, middle schools, and elementary schools have also been able to start CubeSat programs of their own. FIGURE 1 shows university students in their clean room taking measurements of a CubeSat they helped to develop. In addi-tion to educational institutions, Government agencies and FIGURE 1: University student taking measurements of a 2U CubeSat (CP9). [Cal Poly]2 CHAPTER 1 IntroductionCubeSat 101 CubeSat 101: Basic Concepts and Processes for First-Time CubeSat Developers NASA CubeSat Launch Initiativecommercial groups around the world have developed cubesats . They recognized that the small, standardized platform of the CubeSat can help reduce the costs of technical developments and scientific investigations.

9 This lowered barrier to entry has greatly increased access to space, leading to an exponential growth in the popularity of cubesats since their inception. In addition, this world of small, affordable spacecraft has gotten more diverse and complicated each year, as more and more researchers find utility in these small document was created mainly for CubeSat developers who are working with NASA s CubeSat Launch Initiative (CSLI), but most chapters also will be useful to CubeSat developers launching through other developer: You ll hear this term a lot in the CubeSat world. This is the standard term for any person or organization that is designing, building, and preparing a CubeSat for s CSLI, you ask? CSLI is a NASA initiative that provides opportunities for qualified cubesats to fly as auxiliary payloads on future launches that have excess capacity or as deployments from the International Space Station (ISS). In very simple terms that means that NASA will cover the cost of providing your CubeSat a ride to space in exchange for a report on the results of your CubeSat of ELaNa 23 RadSat-G CubeSat from Montana State University in orbit around Earth.

10 [Montana State University]CSLI enables NASA to develop public-private partnerships that provide a low-cost platform for NASA science missions, including planetary exploration, Earth 3 CHAPTER 1 IntroductionCubeSat 101 CubeSat 101: Basic Concepts and Processes for First-Time CubeSat Developers NASA CubeSat Launch Initiativeobservation, and fundamental Earth and space science. These efforts are a cornerstone in the development of cut-ting-edge NASA enabling technologies including laser communications, next generation avionics approaches, power generation, distributive sensor systems, sat-ellite-to-satellite communications, and autonomous movement. Leveraging these missions for collaboration optimizes NASA s technology investments, fosters open innovation, and facilitates technology infusion. CubeSat missions are enabling the acceleration of flight-qualified technology assistance in raising Technology Readiness Levels, which aligns to NASA s objective of advancing the Nation s capabilities by maturing cross-cutting inno-vative space (Attitude Related Maneuvers And Debris Instrument in Low (L) Orbit) is a 3U CubeSat under development at the University of Texas at Austin.
