Problem Statements

Human Health and Environmental Control & Life Support System (ECLSS):

• The health effects of long-duration exposure to deep-space radiation and reduced gravity are poorly understood, as are effects on microbes and microbiomes relevant to food production and life support. Beyond-LEO experimentation is needed to understand, manage, and mitigate effects on health, performance, and critical support systems.

Fundamental Space Biology:

• SMD/Biological & Physical Sciences and PSD/Astrobiology need access to combined deep-space radiation and relevant gravity ranges to study space processes and measure effects on organisms and biomes.

Deep Space Technology Development

• ESDMD and STMD need frequent access to platforms providing relevant environments for efficient testing and development of deep-space technologies.

Goals and Objectives

Goals: Develop beyond-LEO (BLEO) multi-payload platform to provide transit-to-Mars and Mars-surface gravity-plus-radiation environments for science experiments, model validation, technology development, & risk reduction.

Objectives:

O1	Simultaneous long duration exposure to deep space radiation environment over a range of (0 -> 1G) gravities simultaneously
O2	Low cost per experiment as many experiments can be hosted on the platform which will provide enhanced statistical significance
O3	Allow for frequent access to space as SpinSat can be launched on most launch vehicles into almost any orbit
O4	Interfaces consist of the highly familiar “Cubesat” interfaces based on the “U” format which allows the PI to focus on the experiment, not the S/C
O5	Easy integration / payload access
O6	Addition of regolith simulant allows for simulation of lunar and possibly Martian radiation environments

SpinSat Addresses PI Needs

• A  highly cost-effective “standardized” secondary-compatible Class D “Plug-n-Play” platform
• Utilizes standard “open source” U-form factors for experiments
• Allows PI to focus on the experiments and not the spacecraft
• Offers increased flight opportunities for experiments needing the combined microgravity effects from near-0 to 1-g simultaneously, deep space or lunar radiation environments

SpinSat Configurations

SpinSat provides alternate “gravity fields” and payload configurations.

There are two mechanical configurations for SpinSat, Side Mount and In-Line.

Side Mount – Designed to be accommodated on an ESPA Grande stretch ring port.

• 1.5m, 330kg spacecraft, 36 rpm

• 32-48U, configuration dependent

In-Line – Designed to be part of the ESPA ring stack.

• 4.3m, 1225kg spacecraft, 21 rpm
• 96U+ of payload

• Requires separator bands between other rings in the stack

Launch Vehicle Accommodation is Easy

SpinSat can be:

• Launched on a variety of launch vehicles
• Into almost any orbit
• Mounted as an ESPA-port secondary payload
• Provide at least 48 ‘U’ worth of experiments
• Multiple SpinSats on multiple ports
• Cost effective
