The Use Of Low-Cost ‘Balloonsats’ For Stem Education With 3d Printing, Jeremy Straub, Josh Berk, John Nordlie, Ronald Marsh
The Use Of Low-Cost ‘Balloonsats’ For Stem Education With 3d Printing, Jeremy Straub, Josh Berk, John Nordlie, Ronald Marsh

A new technology, known as 3D printing, allows the rap-id fabrication of plastic structures of virtually any config-uration. These structures are light-weight, dura-ble and inexpensive. This paper considers the utility of utilizing 3D printing to create enclosures for ‘BalloonSats’ – small, low-cost spacecraft analog which can be utilized by students to understand space engi-neering, conduct near-space science (e.g., physics, bio-logical and other experiments) and touch the edge of space.
Assessment Of Educational Expectations, Outcomes And Benefits From Small Satellite Program Participation, Jeremy Straub, Ronald Marsh
Assessment Of Educational Expectations, Outcomes And Benefits From Small Satellite Program Participation, Jeremy Straub, Ronald Marsh
Jeremy Straub
This paper begins to characterize the educational outcomes that can be produced from student participation in a small spacecraft development program. We asked students what benefits they expected to receive from program participation and we asked them, at the end of the semester, what benefits they had received. We also characterized student performance through the use of post-participation Likert-like scale questions and the use of a widely-used questionnaire for assessing student research participation outcomes. We compare benefit expectation and attainment, characterize the level of benefits received across multiple types of participation and assess the effect of program participation on subject-specific …
Solar Ballooning: A Low-Cost Alternative To Helium Balloons For Small Spacecraft Testing, John Nordlie, Jeremy Straub, Chris Theisen, Ronald Marsh
Solar Ballooning: A Low-Cost Alternative To Helium Balloons For Small Spacecraft Testing, John Nordlie, Jeremy Straub, Chris Theisen, Ronald Marsh

Helium-filled latex weather balloons have been utilized to carry small satellite prototypes and subsystems into the stratosphere to allow testing in a “near space” environment. This provides a variety of environmental factors similar to the space environment, such as a rarified atmosphere, increased thermal stress, increased solar radiation, the necessity of remote command and control, tracking, and telemetering of data. While this method of flight testing has been well-proven, a recent spike in the price of helium has driven the cost of such test programs to much higher levels. In this poster, an alternative technology to provide the flight mechanism, …

Small Spacecraft provide an excellent platform for the collection of geospatial data. In order to enable the low-cost creation of small remote sensing space-craft in a university environment, a training pathway for students is required. The Realistic Operational Ob-ject for Facilitating Software Assessment and Testing (RoofSat) serves to provide students with experience developing software for a small satellite platform typi-cal of those used for remote sensing missions. It al-lows software to be tested with hardware that re-sponds in a similar manner to that found on the satel-lite for a fraction of the cost of development. This poster details the goals …
Educational Outcomes From The Openorbiter Small Spacecraft Development Program, Jeremy Straub
Educational Outcomes From The Openorbiter Small Spacecraft Development Program, Jeremy Straub
Jeremy Straub
The OpenOrbiter program [1] is developing a low-cost framework for the creation of space-craft by researchers and educators worldwide [8]. In addition to the technical objectives, ed-ucational assessment [2, 3] has also been a key focus. Students working on development of the spacecraft [4] were asked what types of benefits they sought from their participation [5]. The assessment of the attainment of these benefits is ongoing, in conjunction with continued development in pursuit of the crea-tion of a set of designs that can be used to build a spacecraft with a cost of under $5,000 [13] .

Research and educational efforts related to space engineering or requiring access to space face significant startup costs. The cost of developing a 1-U (10 cm × 10 cm × 11 cm) CubeSat from scratch can be approximately $250,000. Those buying a kit must pay amortized vendor development costs on a per-mission basis, creating a lower per-mission barrier. Kit users are also constrained by being unable to make changes to vendor subsystems without incurring substantial redevelopment costs or vendor charges. The Open Prototype for Educational NanoSats (OPEN) is changing this by providing freely available design documents for a 1-U CubeSat class …

Students at the University of North Dakota, as part of faculty-mentored teams in a student-lead program, are working to broaden participation in humanity's exploration of space. The OpenOrbiter Small Spacecraft Development Initiative (OSSDI) is demonstrating two complementary paradigm-changers. First, the initiative facilitates student involvement in all aspects of a space program, without the preconceptions present in established space activities. Second, it is demonstrating a low-cost framework for small spacecraft development. These combined activities are poised to demonstrate a new way forward for space exploration: combined, they allow risk-taking exuberance and a cost of entry that makes risk-taking exuberance acceptable, even …

The OpenOrbiter program at the University of North Dakota is a student-initiated, student-run effort to design, develop, test, launch and operate a CubeSat-class spacecraft to validate the designs of the Open Prototype for Educational NanoSatellites (a framework that will be made publically-available to allow faster and lower-cost missions at other educational institutions worldwide). OpenOrbiter involves (at various participation levels) over 200 faculty and students spanning five colleges and ten departments. To coordinate this large group of participants who comprise over seventeen teams and work at disjoint hours in a plethora of locations, online project management, software source control and hardware …
