Cubesat Deployable Solar Panel System, Thomas Mcguire, Skye Leake, Michael Parsons, Michael Hirsch, Benjamin Kading, Jeremy Straub, David Whalen

Jeremy Straub

CubeSats are small spacecraft with a nominal size of 10 cm x 10 cm x 10 cm and a mass of 1.33 kg [1] (though some launch providers are now supporting expanded mass levels). While the CubeSat form factor has re-duced the time and cost of spacecraft development, the required resources are still beyond the grasp of many colleges and universities. The Open Prototype for Educational Nanosats (OPEN) aims to solve this problem. OPEN is an inexpen-sive modular CubeSat that can be produced with a parts budget of less than $5,000 [2]. The OpenOrbiter pro-gram is working to develop this …

The Development Of A Nanosatellite-Class Sunsat At The University Of North Dakota, Corey Bergsrud, Jeremy Straub, Robert Bernaciak, Subin Shahukhal, Benjamin Kading, Karl Williams, Hossein Salehfar, Johnathan Mcclure, James Casler, David Whalen, Elizabeth Becker, Sima Noghanian

This poster presents the details of work on the SunSat spacecraft design initiative at the University of North Dakota. This project seeks to advance technologies1 and to increase public awareness of Space Solar Power based via visualization, science and engineering work. It will also focus on the development and demonstration of a workable solution and consider the economic benefits2 that the proposed (and alternate) solutions may generate. This poster details the design project which will construct a transmitting Nano Space Solar Power Satellite (NSSPS) and a power reception satellite for a space-to-space Microwave Wireless Power (MWP) demonstration. The SmallSatstyle spacecraft4, …

Open Beyond Orbit: Using The Designs From The Open Prototype For Educational Nanosats Outside Of Earth Orbit, Jeremy Straub

Jeremy Straub

This paper presents an overview of the Open Prototype for Educational NanoSats (OPEN) and its prospective use in interplanetary missions. OPEN is framework to facilitate the low-cost creation of CubeSat-class spacecraft via using publically available (provided by the OPEN project) de- signs, software, fabrication instructions and test plans. The base open configuration is designed to be able to be produced with a parts budget of under $5,000. Despite this low cost, it is a very ro- bust spacecraft (with capabilities meeting or exceeding many of the vendor-kit solutions which cost eight-or-more times this amount).

Two approaches for using the OPEN …

A 6-U Commercial Constellation For Space Solar Power Supply To Other Spacecraft, Corey Bergsrud, Jeremy Straub

Jeremy Straub

This poster presents early stage planning for a constellation

of 6-U CubeSats which will collect power from

the sun and supply it to other spacecraft in Earth orbit. Unlike

solar panels (which have a known decay rate), antenna

systems (such as would be required to receive microwavetransmitted

power) do not substantially decay over the

typical (or prospectively extended, under this model)

spacecraft lifetime. This allows a spacecraft to be built for

long-term operations (utilizing an electric propulsion technology

and/or a greater supply of conventional propellant)

and receive power from a lower-cost utility provider

spacecraft, which can be replaced on a …

Small Satellites With Micro-Propulsion For Communications With The Lunar South Pole Aitkens Basin, Samudra E. Haque, Jeremy Straub, David Whalen

Jeremy Straub

A lunar sample return mission to the Lunar South-Pole Aitkens Basin (LSPAB) has been highlighted as a high priority objective of the most recent (2011) Decadal Survey for Planetary Science, by the National Research Council. This class of mission, however, faces a dramatic communications limitation, due to the lack of a frequent, or continuous, line-of-sight communications path to Earthbased ground stations. Brunner and others have proposed a communications system utilizing Low Lunar Polar Orbits (LLPO) and Lunar Halo orbits for this purpose. Ely and others have outlined proposals for using several communication satellites to form a relay network using LLPO, …
