🚀 Welcome to the Starship Use Cases Hackathon!

Starship, a super heavy-lift launch vehicle under development by SpaceX, with its transformative potential, paves the way for humanity to reach new frontiers—whether it's the Moon, Mars, or beyond. We are steadfast in our belief of pushing the boundaries of what's possible, propelling ourselves to the stars.

At the Starship Use Cases Hackathon, our mission is simple yet profound: to inspire and empower space enthusiasts, engineers, and innovators to envision groundbreaking solutions for the future of space exploration.

🌟 We're excited to share several key highlights of this hackathon:

  • Curated Use Cases: We've carefully selected a range of engaging use cases that provide hackers with a solid foundation to build their innovative solutions on.
  • Prize Pool: We've put together a prize pool of $100,000 to reward and motivate hackers as they embark on their building journey.
  • Hacker Resources: Explore a curated selection of valuable tools to enhance your solution design, featuring a range of purpose-specific calculators.
  • Inspiring Workshops: Join us for inspiring workshops led by experienced professionals from the space industry. Gain valuable insights and knowledge to supercharge your hackathon experience.
  • Expert Feedback: Our panel of judges will offer constructive feedback to help hackers refine and enhance their solutions. It's a great opportunity for growth and improvement.
  • Collaboration Hub: Connect with fellow hackers on our platform! Build teams, exchange ideas, and inspire each other throughout the hackathon journey.

Join forces with fellow space buffs and embrace the challenges and opportunities that lie ahead. Get ready to showcase your technical skills. Together, we will transform dreams of interstellar adventures into tangible reality.

Ad Astra! 🌠

Use Cases

Overview: From the Wikipedia page for SpaceX Starship, the lift capability of a fully reusable Starship is at least 100 tones to LEO. From there, lift capability drops significantly (only about 20 tonnes to GTO, for example), but the possibility of on-orbit refueling can provide the capability to lift 100 tonnes into essentially arbitrary trajectories, limited only by fuel availability. The payload bay is 8m in diameter and 17m long (although heavily tapered toward the nose). Considering this impressive lifting capacity, we've thoughtfully curated the unique use cases and open challenges below. These scenarios provide an excellent opportunity for you to showcase your engineering expertise and explore your imaginative potential as you create your design blueprints.

Note: For in-depth background and task description for each use case, head to the Use Cases tab.

Use Cases:

  • Delivery of Water to the Lunar Surface
  • Space-based Farming
  • Orbital Hotel
  • Artifact Collection
  • Orbital Fireworks
  • Planetary Defense System
  • Space Debris Cleanup
  • Collision Avoidance for Immobile Objects
  • Satellite Secure Digital ID
  • Add-on Passive Deorbit Hardware
  • LIDAR Constellation
  • Routers for Global Internet of Things
  • Buried Among The Stars
  • Climate Engineering the Easy Way
  • Metals from the Moon
  • Orbital Lab Bench
  • Storage of Sensitive Data in Space
  • Preserve the ISS
  • And more use cases to come!

Open Challenges:

  • Novel Satellite Constellations
  • Recreation Facilities for Space Hotel

Prize Details:

A total prize pool of $100,000 USD, comprising 2 award categories:

🏆 Top Honors: $10,000

🌟 Project Awards: $500 - $2,000 (Varies based on project quality)

There is no restriction on the number of winners in each category until the entire prize pool has been distributed. In case we don't have enough eligible projects to claim these rewards, the remaining prize pool will be rolled over to the next round of this hackathon or allocated to future Space hackathons.

Submission Requirements

  • Each submission should address a single use case or the open challenge.

  • Please submit a well-crafted design report that incorporates the provided technical constraints for each use case. Ensure it offers a comprehensive explanation of how your design aligns with the use case objectives and performance criteria. Your submission should reflect thoughtful consideration and attention to detail, demonstrating your engineering skills and capability.

  • Please feel free to include links to detailed reports (e.g., GitHub repo, Google Doc, or Google Drive folder) alongside the BUIDL page's description.
