1.1 Project Scope

Project Description

The purpose of this project is to design a storage unit to be utilized on the NASA/JPL

mission to Psyche. Psyche is a metallic asteroid, believed to be the remnants of a planet torn

apart by asteroids, leaving behind nothing but the exposed core. This storage unit will be a key

piece of exploration equipment used to collect samples from Psyche. Due to the nature of the

mission and the small amount of information known about Psyche, the unit will be designed with

all possible environments in mind. This unknown world forces our team to think outside the box

and create a unit with a high level of versatility. Additionally, coordination with a separate end-

effector team is crucial to achieving our end goal of a modular system which works together to

perform the task at hand.

Key Goals

The primary goal of this project is to design a storage unit for the NASA/JPL mission to

Psyche. The storage unit should be capable of accepting samples from the asteroid and protecting

them as they are transported from the asteroid back to Earth aboard a return vehicle. The unit

should be designed such that it works in conjunction with an end effector, as specified by Team

501. Due to the unknown environment present on Psyche, this storage unit will need to be

designed as a universal solution, capable of performing its stated function in any number of

environments and climates.

Team 502 11

Market

The primary market for this project is the NASA/JPL Psyche Mission. Secondary

markets include other NASA or JPL missions that benefit from a well-designed storage unit, as

well as missions performed by other organizations. This unit could also be used for small scale

mining, sampling, or transportation operations on Earth. In areas where manned operation is

infeasible, such as radiation zones or hazardous mines, this storage unit could be used in

conjunction with a transport vehicle and sampling device to move samples towards a safe

location for inspection.

Assumptions

The following assumptions were made based on discussions with our sponsor, our project

manager, and Team 501:

The Storage unit will be removed from and returned to the return vehicle. This will be

accomplished by the rover team, and will involve lifting the storage unit, mounting it to the

rover, transporting it to various locations on the asteroid, returning it to the return vehicle,

removing it from the rover, and placing it in the return vehicle. Methods of manipulation and

mounting may be fleshed out with the rover team.

It’s also assumed that the Psyche surface will be excavated by a separate end-effector

unit. This end-effector will be different from the end-effector being designed by Team 501 and

will specialize in core sampling.

The gravity on Psyche will be present but very weak. This is a small asteroid and has a

gravitational pull of 0.06m/s, which is 1/27th that of the moon.

Team 502 12

2021

Psyche is considered a Type M (Metallic) asteroid. As such, no life is expected to be

found on it, so no measures are needed to preserve life.

Psyche could experience temperatures as low as -114°C, based on its maximum orbital

distance from the sun. Although temperature considerations are not needed for the samples, the

storage unit itself will need to be designed to operate in extreme temperatures. (2)

Psyche is assumed to have no atmosphere. It is assumed to be a non-gaseous, metallic

asteroid. As such, it is assumed that the pressure on Psyche will be vacuum.

A rover will be capable of accommodating the power requirements of the storage unit

during sampling. However, the storage unit will not always be on the rover and may need to be

opened without a supplied power source. As such, the storage unit will need to have an onboard

battery capable of being recharged by the rover and the return vehicle.

The samples are not temperature sensitive. The samples are not expected to harbor life

and will not need to be kept in a temperature-controlled environment. They will, however, need

to be sealed to the elements so that they are not contaminated until they are ready to be studied.

Stakeholders

The parties involved for this project are the National Aeronautics and Space

Administration (NASA), Arizona State University (ASU), Dr. Cassie Bowman (Sponsor/Psyche

Co-Investigator), Dr. Shayne McConomy (FSU Senior Design Professor), Dr. Patrick Hollis

(Engineering Advisor), Kimberly Rillon (Project Manager/ASU Student), Dr. Lindy Elkins-

Tanton (Principal Investigator of Psyche), and the FAMU-FSU College of Engineering’s Senior

Design Team 501.

1.2 Customer Needs

The objective with meeting with our sponsor was to receive a list of needs that will help

us shape our storage unit to safely store Psyche specimens to be returned to earth. These

questions were asked over Zoom, a video conferencing software program. For identifying the

customer needs, the following questions were interpreted through discussions with our sponsor

Dr. Cassie Bowman and the project manager Kimberly Rillon which are shown below in Table

1.

Question Number Question Customer Answer Interpreted Need 1 Should we expect the

storage unit to encounter any corrosive materials?

Yes, corrosive materials should be planned for.

Materials incorporated into the final design can exhibit a resistance towards harmful substances.

2 How many separate compartments are required?

No specific number is defined but you may consider making a unit whose size can be changed with little other considerations.

The designers decide on a relevant number and create a system which can grow or shrink without substantially modifying the rest of the system.

3 Does the storage unit need to be able to withstand impact from flying debris?

There could be debris flying around but nothing too devastating.

The storage unit materials can withstand light impact from flying debris.

4 Does the storage unit need to protect samples from blunt impact?

Yes, it’s possible that the storage unit will encounter drops to Earth’s surface.

The storage unit can protect samples from surface impacts.

5 Will the rover return to the ship or just the storage unit?

This information is not yet decided on, you may want to

of transportation will lie outside of our project scope

6 Should we be concerned with temperature change?

Psyche will subject the unit to extreme temperatures which your team will need to deduce.

The unit can withstand extreme temperatures of Psyche.

7Is anything known about the atmospheric pressure on Psyche?

Psyche is assumed to have no atmosphere.

The unit may need a mechanism to compensate for pressure change such that it does not rupture.

8Should the storage unit be sealed?

The unit should prevent foreign particle contamination.

The storage unit can protect the core samples from the elements.

9Does the storage unit need to support weight from external addons?

Addons are possible. Components can be mounted on the unit.

10Are there maximum or minimum outside dimensions for the storage unit?

The storage unit size should be able to accommodate samples for all hypothesized surfaces on Psyche.

The storage unit has enough space for samples from all hypothesized surfaces of Psyche.

11What will the average specimen size be?

You would have to contact other Psyche project groups to see what their plans are.

The size of each storage compartment can be adjusted without major adjustments to the rest of the system

12Should the storage unit be capable of detaching from the rover?

Yes The storage unit can detach from the rover.

13How long is the storage system expected to remain on Psyche?

That hasn’t been decided yet, but you should plan for months to years.

The system can last for years.

Is the storage unit No, just worry about Primary focus can be

15Will the storage unit ride on the inside or outside of the return vehicle?

The unit will be inside the return vehicle.

The unit is small enough to fit in the return vehicle.

Synthesis

Our final prototype needs to be capable of storing and protecting core samples taken from

a vaguely understood metallic asteroid known as Psyche. Although the environmental

characteristics of the asteroid are relatively unknown, it can be hypothesized that the storage unit

will be subjected to extreme cold and high heat. Although the samples are not temperature or

pressure sensitive, the storage unit itself will need to function in this environment, so climate

control will need to be considered for the vital components, and pressure in the storage unit will

need to be controlled such that the unit does not rupture. The samples will also need to be

protected from Earth’s atmosphere, so they will need to be sealed to the elements. The unit will

also need to be tough enough to withstand possible damage from small meteorites, as the asteroid

has no hypothesized atmosphere. Overall, the unit needs to be tough, versatile, situationally

independent, and needs to protect the core samples from direct and incidental damage, and

elemental contamination.

Our team is committed to satisfying the needs of our sponsor and stakeholders while adhering to the culture and values of their institution as well as we would our own. We will accomplish this by pushing the limits of current technology, which in turn will pave the way to a more vibrant, technologically advanced tomorrow.

 2 Team Roles

 To designate roles for the project, each team member provided some information

about their interests and areas of higher proficiency in the various realms of mechanical engineering. Roles were then generated and designated as shown below:

  Mechanical Systems Engineer: Mechanical systems engineers are responsible for

designing and interpreting mechanical systems. This role is currently assigned to Marcus Hatchett.

Controls System Engineer: Controls Systems Engineers are responsible for linking any relevant systems together to work as one. They are responsible for designing and implementing controllers. This role is currently assigned to Marcus Hatchett, Michael Macedo, and Luke Remillard.

Design Engineer: Design engineers are responsible for the functional and aesthetic design of the system. They will use CAD software to aid them in their work. This role is currently assigned to Luke Remillard.

Thermal Systems Engineer: Thermal systems Engineers are responsible for designing and implementing a system that controls the temperature of the storage system. This Role is currency assigned to Robert Zube.

Fluids Engineer: Fluids engineers will be responsible for any fluid motion required by the project. This could include anything from aerodynamics to fluid transport throughout the system. This role is currently assigned to Robert Zube.

Materials Engineer: Materials engineers will be responsible for determining the appropriate material to be used in each aspect of the system. They will be required to select materials based on several requirements set forth by each specific application. This role is currently assigned to Robert Zube.

Systems Engineer: The role of systems engineer will be used to effectively coordinate with the other team involved in this project. This will involve communication with the other team as well as being responsible for data and target management between the two. This role is currently assigned to Kimberly Rillon.

Project Manager: The project manager is responsible for delegating roles and keeping track of deadlines for future assignments. They will also schedule the

Team 502 20

2021

deadlines within the Basecamp app. This role is currently assigned to Kimberly Rillon.

 If other duties are required, the topic will be presented at a scheduled group

meeting where team members will collectively decide who is best suited for the role. This decision will be based on relevant factors including but not limited to each team members knowledge in the specific area of the role, and each team member’s current workload within the project. It is also expected that each team member remains fluid within their role and helps their colleagues whenever possible. These roles are subject to change based on individual performance within each role. Should a change be desired, the issues must be brought up at a scheduled meeting where team members will discuss necessary changes.

 3 Methods of Communication 

 Methods of communication with team members will be facilitated through

Microsoft Teams, email, Zoom, Basecamp, and group messaging applications. All communication with advisors, sponsors, and other collaborators outside of the team will be done so in a professional manner via email, Zoom, Basecamp, or other virtual meeting software.  

Communication that concerns the joint effort between teams 501 and 502 will be conducted via the same methods yet be separate from the inner-team communications. Through coordination with team 501, these meetings will be conducted at least once per week on Thursdays after being dismissed from Senior Design. In some cases, the need for more meeting time between our groups may be necessary. 

Important information and tasks given in both the regular and joint team meetings will be recorded during each meeting. This will be completed every meeting to the best of our ability. 

 4 Dress Code 

All members of team 502 are expected to dress appropriately to all team and collaborative functions. These scenarios include but are not limited to the following:

Presentations: Business Professional  Sponsor/Advisor Meetings: Business Casual  Team Meetings: Casual  Inter-team Meetings: Casual

 

Team 502 21

2021

5 Work Schedule

Team 502 will plan to meet weekdays starting at 6:30pm ET and work as needed to accomplish the task at hand. This start time is flexible. A minimum of nine meeting hours a week is desired. Team 502 will meet bi-weekly on Wednesdays with our project advisor, Dr. Cassie Bowman, from 6:00pm to 6:30 pm ET. Team 502 will also meet weekly, on Thursdays at 6:30 ET with Team 501 to discuss cross compatibility as well as other inter-team topics.

6 Attendance Policy  

Attendance will be mandatory for all scheduled meetings and collaborations. Should a team member be unable to attend a meeting, they should inform all other members at earliest possible convenience and state the reason for why they cannot attend. Attendance of all scheduled meetings will be recorded as part of the meeting minutes to ensure team members are active. Should a team member be unable to attend, the reason (if available) should be recorded with the attendance of each meeting.   

7 Ethics and Honesty Policy 

The members of this team will uphold a respectful attitude towards all colleagues and outside collaborators. The acts of lying and cheating will not be tolerated. Each team member is expected to avoid conflict with other team members as well as outside collaborators. Team members are expected to avoid legal issues such as plagiarism and copyright. If any legal or other conflict should arise, the team member(s) involved should alert the rest of the team immediately and contact the appropriate people as soon as possible.  

8 Amendment Policy 

This code of conduct is subject to change at the discretion of Team 502. Should a change be desired, the idea must be presented at a scheduled meeting where all four members of the team are present. The proposed amendment will then be reviewed by all team members and each team member will then vote to either amend or reject the change. A 3-member majority will be required to execute any changes.

  9 Decision Process 

All decision regarding this project will be made as a team. Decisions which only affect team 502 will be put to a vote during scheduled team meetings where a three fourths majority is required to pass a decision. Decisions that affect both teams 501 and 502 will be discussed and voted on during scheduled inter-team meetings. These

Team 502 22

2021

decisions will also require a three fourths majority to pass. All decisions which affect the sponsor and/or advisor will be discussed with the respective parties before being made. In a situation like this, input from a senior party will always weigh higher than our own opinions.

The text above the cation always introduces the reference material such as a figure or

table. You should never show reference material then present the discussion. You can split the

discussion around the reference material, but you should always introduce the reference material

in your text first then show the information. If you look at the Figure 1 below the caption has a

period after the figure number and is left justified whereas the figure itself is centered.

In addition, table captions are placed above the table and have a return after the table

number. The second line of the caption provided the description. Note, there is a difference

between a return and enter. A return is accomplished with the shortcut key shift + enter. Last,

unlike the caption for a figure, a table caption does not end with a period, nor is there a period

after the table number.
