A Bent-Pipe Microwave Wireless Power Transfer Spacecraft For Relay To Unserved Regions, Jeremy Straub
A Bent-Pipe Microwave Wireless Power Transfer Spacecraft For Relay To Unserved Regions, Jeremy Straub
Jeremy Straub
This paper seeks to begin a discussion about the efficacy of using a ‘bent pipe’ transmission concept (familiar to those in the communications satellite arena) for power transfer. It presents the ‘bent pipe’ concept and provides a brief qualitative consideration of the benefits of this approach. It also begins the process of quantitatively considering the efficacy of a ‘bent pipe’ mission by exploring the trade space related to frequency, antenna size and altitude.

The design of a manned Mars mission has been a point of ongoing interest . Numerous Mars missions have been proposed and designed but major roadblocks impair their completion. Primarily, these issues are related to cost and safety concerns. However, many technologies have been developed and are being developed to make a Mars mission more feasible. One such technology is Space So- lar Power. (SSP) SSP technology involves generating power in space from the sun and beaming it via microwave radia- tion to a ground site for use. This method has immediate usability on Mars due to the minimal atmosphere, …

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 …

Wireless power transfer (WPT) can be used to deliver space-generated power to ground stations through the use of microwave beams. WPT satellite power delivery systems have two major failure states: misdi-recting a beam and failing to send power to a station. This project has implemented an expert system to perform pattern recognition in an effort to prevent failures by analyzing the system state and predicting potential failures before they happen in support of space-based testing [1] and deployment [2].

Jeremy Straub
Once proposed work in low-Earth orbit [1] to demonstrate the efficacy of wireless power transmis- sion is a mission is completed, an additional step is needed before the technology is sufficiently tested for use on Earth. A Martian mission (such as [2]) is pro- posed to allow the demonstration of the use of the wireless power transmission technology in support of and proximity to human astronaut operations.
This poster presets a satellite concept intended for use on this Mars mission, to supply power that is need- ed for human habitation and other purposes. This satel- lite is designed to be …

Rocket Flight Path, Jamie L. Waters
Rocket Flight Path, Jamie L. Waters
Jamie L Waters
This project uses Newton’s Second Law of Motion, Euler’s method, basic physics, and basic calculus to model the flight path of a rocket. From this project, one can find the height and velocity at any point from launch to the maximum altitude, apogee. Once complete this can be compared to what the actual values were to see if the method is a plausible way of estimation. The rocket used in this project is modeled after Bullistic-1 which was launched by the Society of Aeronautics and Rocketry at the University of South Florida.
A Control System For Space Solar Power, Jeremy Straub
A Control System For Space Solar Power, Jeremy Straub
Jeremy Straub
This poster presents an algorithm for the implementation of a control system that accepts power requests and makes distribution assignments to maximize the performance of the overall space solar power (SSP) system and meet service level agreements (SLAs). This complex process involves projecting service-customer demand into the future, projecting power availability on each servicing spacecraft and implementing corrective measures should actual craft performance not meet with planning expectations. The control system is implemented as a planning problem with some deterministic elements (craft position and generation) and some probabilistically predicted elements (interference, drag and malfunctions). A heuristic solver is proposed that …
Open Beyond Orbit: Using The Designs From The Open Prototype For Educational Nanosats Outside Of Earth Orbit, Jeremy Straub
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
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, …
