MIL:RS Coring Device
The modular intuitive lightweight regolith sampler (MIL:RS) is equipped with an internalized sample storage compartment for each core and test bed sample. It is designed for the ergonomics of an EVA suit, and micro-gravity using our innovative approach to sample retention which is inspired from the practical function of a Chinese finger cuff. We feel that this is the optimal approach for taking core samples in micro-gravity, based on our experiments and experience with sand and aggregate material. The form of our design has a lot to do with ergonomics and mechanical features that are designed to be fail resistant. All mechanisms and structures within the MIL: RS are self-enclosed and easy to use based on the requirements of an EVA suit. The prototype is comprised of rubber grips, compression molded bodies and case, acrylic tubing, and aluminum fasteners. These will materials will not interfere with elements of the NBL environment. As well as providing a resilient, and effective platform for taking samples in outer space.

ZOIDBERG 2.0 Float Sample Grabber
The National Aeronautics and Space Administration (NASA) as part of the Asteroid Redirect Crewed Mission (ARCM) (2) will be conducting an Extra-Vehicular Activity (EVA) to explore the surface of an asteroid and collect geologic samples. NASA is extending a design challenge to undergraduate research teams to build a prototype float sample grabber which could be used in such a mission. The Boise State University Undergraduate Microgravity Research Team is proposing a tool called the Zero-g Operable Interplanetary Delivery Based ERgonomic Grabber 2.0, (ZOIDBERG 2.0). The tool is able to collect three samples with no cross-contamination, and is compatible with the new Modified Advanced Crew Escape Suit (MACES) (7). ZOIDBERG 2.0 follows a successful though improvable test of the ZOIDBERG 1.0 at the NBL. This year’s goal is to test the next evolution of the ZOIDBERG platform. The new Sample Collection Boxes (SCB), which have been modified to better capture geologic samples, are attached to a rack and pinion actuated carousel that is advanced using a new ambidextrous linear translating Charging Handle. Ergonomics are improved by a Handle that is more natural to hold and an Actuator with reduced spring force, reducing fatigue. Further improvements include a clear viewing window for sample capture verification and a new keyed attachment mechanism that allows for interchangeability of SCBs. Furthermore, the team is developing an extensive outreach plan by establishing a mentoring partnership and leading lesson plans with two local schools, and by maintaining a strong presence in the community through multiple events. This proposal outlines the new design of the tool, the outreach plan, and the proposed tests at the Neutral Buoyancy Laboratory (NBL) which will validate the performance of ZOIDBERG 2.0 as a viable Float Sample Grabber.

PALLAS: A Portable Asteroid Lift and Lock Aggregate System
NASA’s recently-released “Journey to Mars” roadmap outlines the intermediate steps necessary to advance the United States’ human spaceflight program beyond low earth orbit (LEO) in pursuit of the eventual goal of a human journey to Mars. While the commercial space industry works hard to maintain and resupply the International Space Station (ISS) via the Commercial Crew and Cargo programs, the agency turns its eye towards the Asteroid Redirect Mission (ARM) in the Journey’s “proving ground,” wherein astronauts will use the Space Launch System (SLS) and Orion capsule to explore an asteroid that has previously been moved into Lunar orbit by a robotic precursor mission. Maximization of productivity during a manned ARM depends on the existence of ergonomically designed, human-operated devices for asteroid sampling. With this goal in mind, Cornell’s Microgravity Research Team has designed a Portable Asteroid Lift and Lock Aggregate System (PALLAS) to allow astronauts to collect and store up to three different float samples without cross-contamination between sites. The device consists of three 3D-printed pods for sample grabbing and storing; these pods are held together securely by a compact aluminum rod assembly. PALLAS functions completely on manual power, and the sample capturing motion can be actuated using only one hand. With a weight of less than 8 pounds, PALLAS is also extremely portable. The team believes that the combination of machining and additive manufacturing techniques used to fabricate PALLAS represents the perfect balance between cost-effectiveness and adaptability. The use of machined aluminum for the rod assembly minimizes the total system cost, while 3D-printing the sample pods allows PALLAS to be rapidly repaired or modified both on earth and in space.

Anchoring Device for Regolith Design and Development
This project will involve the design and development of an anchoring device for use on an asteroid surface. The system’s purpose is to successfully anchor an astronaut to regolith in microgravity, allowing them to take samples and collect data from the environment. The overall design is centered around a drill, involving pneumatic technology and an auger-based design enclosed in a protective kevlar sheath. This device will be submerged within the neutral buoyancy pool at a temperature of +82° F (27.8° C) to +88° F (31.1° C). If the anchoring device is effective at keeping the diver secure while mining the asteroid simulants, the mission will be considered a success.

Isolate Regolith Inspection Sampler (I.R.I.S.): a Coring Device for Loose Regolith in Microgravity
The aim of this proposal is the design, manufacturing and testing of a coring device for loose Regolith in microgravity. In this document, this device will be referred to as “Isolate Regolith Inspection Sampler” (I.R.I.S.). The I.R.I.S. consists of three main components: an outer threaded casing with drilling capabilities; an inner core used for sample collection and retention and a handle for securing the regolith sample inside the core. The outer casing features: an auger-like drilling feature capable of coring the regolith; cutouts for the insertion of the handle and a 1 inch tether attachment point. The inner core features: a clear tube; cutouts to match the ones in the casing; a toggle-able iris capable of assuming an open and a close configuration while inside sediment, and a cam ring connected to the iris in order to assist in its opening and closing. The handle is inserted through both the outer casing and the inner collection tube and it is connected to the iris through the cam ring. Upon turning the handle 180 degrees, the iris can open and close. The lever is activated by hand and its rotating motion prompts the iris to close off the sample while still inside the sediment. This guarantees the integrity of the sample while preserving the layers of the regolith in their native orientation. This three-component design allows for multiple inner cores collection units to be used within the same outer casing.

FLOAT SAMPLE GRABBER FOR NEA MISSIONS
To obtain samples from a mission such as exploring an asteroid, the Oklahoma State Microgravity team has selected to design a float sample grabber. Since there is strong evidence that many asteroids consist of rubble piles, the team decided to focus on a device that can scoop up samples. Furthermore, this was a strong reason for choosing this option; the float sample grabber could be used in any other of the missions to collect the samples found/obtained by the other tools proposed. The device is comprised of multiple sample containers that are all operated individually by a unified single handle. This system would allow an astronaut to easily collect multiple samples and not have to worry about sample cross contamination. The device will be made of aluminum and acrylic plastic, both of which are durable materials that would allow the device to work under all conditions. This device is ultimately made to facilitate astronauts’ work on their mission by being easy to handle, light weight, and small.

Polymeric Attachment Device
Due to the microgravity produced on small bodies, such as asteroids, it is extremely difficult to remain in contact with the surface in these environments. Taking real-world methods and missions into consideration, problems have occurred when attempting to anchor even small devices to surfaces in microgravity when using conventional hook and tether methods. Our team, composed of Ian Haskin, Nathan Sivertson, Alec Ferley, Andrew Hibbs, Dana Lambert, and faculty advisor Dr. Robert Ash, is investigating a new design approach to enable astronauts and robotic machinery to remain in contact with the surface while performing various exploration activities. Combining the simplistic function of hook and tether devices, with inspiration from methods used in local shipyards, our intended solution is a mechanical apparatus that utilizes pneumatic concepts and an ejectable compound that will fully anchor and withstand an applied ten pound force. The focus of this design was determining how to best incorporate a quick-setting compound into a proven anchoring method, as this fusion of concepts is the defining characteristic of the team’s design and seems least understood and tested. The proposed prototype consists of a hollow aluminum pipe, two sets of hooks, a two-part cement compound housed in a 3D printed internal cell, and a pneumatically assisted applicator gun. Upon its insertion into the regolith, the device will be twisted, causing a set of flanged barbs to open and resist any further moment applied. After the hooks are extended, the compound will be forced through a mixing section via a pneumatic applicator gun and ejected through a nozzle, resulting in the extension of a second set of hooks. The compound will disburse throughout the local regolith and harden within a brief period of time, creating a mass of regolith to be permanently secured to the lower end of the anchoring device.

U.A. The CLaW
The CLaW has been created to serve the function of collecting and containing three separate float samples harvested from various sites. This tool’s primary design feature is its ability to capture and contain the samples with minimal exertion by the operating astronaut by utilizing three separate collection and storage spheres mounted on a rotating central track. By using containment cells that simultaneously act as the capture unit, the design goal is to ultimately reduce the actions required by the astronaut (at most three) and protect the samples from cross contamination. The three major components of the tool are its capture and containment spheres, rotating hub, and grabber claw. The spheres serve the function of capturing and containing the sample. The rotating hub controls the action of exchanging from one container to the next. The grabber claw controls the actuation of opening and closing the sphere as well as releasing the containment spheres to rotate.

STRAHL Boom
The STRAHL boom allows astronauts to traverse between Orion and the Asteroid Redirect Vehicle (ARV). The members of STRAHL have designed a safe, portable, and ergonomically friendly Gap Spanner Boom (GSB) and ARV Coupler. The coupler attaches to the ARV Mockup and receives the GSB which locks into place. The boom is made up of four telescoping tubes that allow the tool to reduce to a smaller, portable size. The cam tip of the boom, which locks the GSB into place in the coupler, resembles a tool used for rock climbing. The tip is able to collapse and easily slide from its locked position through the use of a simple pull cable. Encased by the boom itself, the cable cannot be pulled or disturbed unless an operator intentionally initiates the removal process of the tool. STRAHL will manufacture the design given so that the test is easily conducted and the use of the tool is intuitive. The operator of the GSB will have complete control from the Orion vehicle throughout the entire experiment. Additionally, the GSB will be easily stowed in a volume of the prescribed size and will remain under fifteen pounds. Though no preliminary testing has been completed, the team plans to implement quantitative and qualitative tests to achieve a safety factor of three and produce a highly functional tool. STRAHL’s main focus is to aid in the operator’s ability to execute a safe and successful mission.
