NASA Contest: 3D CAD Models/Animations of Three Different Radiation Shielding Concepts

  • Status: Open
  • Prize: $1000
  • Entries Received: 0

Contest Brief

This challenge is seeking high quality CAD models and animations of three different radiation shielding concepts for a Mars spacecraft.

In a previous challenge, we asked for novel folding/origami-based concepts for packaging and deploying a large radiation shield around a Mars vehicle in cis-Lunar space. From that challenge, we had three top selections. Each selection had positive benefits and areas for improvement and we are looking for ideas on how to enhance those benefits and make improvements where needed.

From this challenge, we are looking for high fidelity 3D CAD models of the stowed and deployed configurations of the shielding concepts, as well as high fidelity animations of how the shield is deployed. The CAD models will be implemented in our 3D radiation transport simulations to understand the total radiation reduction to astronauts from these configurations. The animations will support engineering design and feasibility studies.

All final CAD model submissions must follow these requirements:
- Format: .prt (SolidWorks or ProE) or .step/.stp (Step file)
- Correct material types must be associated with each object in the CAD file
- If there are any hollow objects, they must be modeled as a hollow object with the appropriate thickness. Do not just define the envelope of an object.
- Enhance benefits of the design and upgrade areas of the design that need improvement

All final animation submissions must follow these requirements:
- Format: .avi or .mov
- The animation shall at a minimum
1. start with the shield in the stowed configuration docked to the Mars transit vehicle
2. show how the shield is robotically deployed – include enough fidelity in the animation to understand any mechanisms that are used as part of the deployment
3. show how the shield is attached to the Mars transit vehicle, given the standoff constraints
4. end with the shield in the fully deployed configuration
- Enhance benefits of the design and upgrade areas of the design that need improvement

Submissions will be evaluated based on the improvements made to the concepts, and the quality and fidelity (detail) of the models and animations produced. Freelancer submissions will need to be image files of your model and animations. Entries should be in JPEG, GIF or PNG formats with an aspect ratio of 6:4 for easier viewing. Animated gifs are not supported. There is also a maximum file size limit of 250 MB. Please provide enough images to allow adequate evaluation.

This challenge will award at least one winner with an award of $1000. For the winning submission, the minimum has to include a CAD model and animation for one concept. Users can provide additional concepts, if they’d like, but at minimum it should be one concept/submission. Multiple submissions may be selected for prize amounts between $100-$500 depending on the submission evaluation.

IMPORTANT: See the attached files for the winning shield concepts with NASA feedback and a reference to the initial challenge details.

Please note that NASA employees/contractors are not eligible for competing in this contest.

    what are the largest available dimensions of the radiation shield sheet -to be able to enter the craft-?
    and how large can you manufacture it?
    what is the minimum number of these sheets to do its function? you say as thick as possible but you didn't give the minimum number.
    thank you :)

      Review the attachment that is labeled "For Reference Only" to answer your questions pertaining to requirements of the initial challenge. Assume you can manufacture the material to the size needed in the concepts. The minimum thickness is the thickness of one sheet of the material.

    Maybe I could ask a question If not being rude ? After checked the top 3 selection l , figured that were't in very nice shape or quality , don't really understand how they selected ? I assume maybe that wasn't your focal point ? Thank you .

      The previous challenge focused on identifying a concept that met the requirements. This challenge is focusing on further refining those concepts and developing high quality CAD models and animations. If you are interested in the details of the first challenge, please look at the attachment noted as reference.

    i have a question, since i cant find the answer in the brief anywhere. does it have to follow the concept of the prior winner?

    If so, do the original winner from the prior contest allowed to enter again? i ask this because i'm really eager to develop the original concept even further. And i already have the assets from the previous contest with me.

    but since the pdf is explaining the concept is quite clear, i suppose it's fair enough?
    let me know your view on this one. i'm really excited if allowed to work on this project further

    thanks in advance :)

      Yes, we would like to further develop the three concepts that were selected. You can make improvements to the current concepts.

      The original winner from the prior contest can enter again. The focus of this challenge is on developing a high fidelity CAD model and animation of the concepts.

    I can't lie, I'm a little bummed I missed out on the prior contest. I've been mentally toying with a concept for an origami-inspired radiation shielding concept for a couple years now. Would've loved to have an excuse to model it out in Rhino.
