About Crowd Capsule -

  • We are team SpaceFlakes from New York City and we built Crowd Capsule
  • In 1977 NASA sent into space gold-plated records containing sounds and image portraying life on earth

Today, Crowd Capsule is remixing the Golden Record with:

  • A globally crowd-sourced digital time capsule designed for interstellar communications
  • Crowd Capsule not only connects us to spacefaring beings it also connects us as earthlings
  • We’ve designed a system in which the citizens of earth from every culture can decide democratically how we will tell and show our story to the universe

Starting out -

  • The first page users see is the most important - the feed
  • This is a collection of user uploads from around the world
  • Anyone can vote up a piece of content based on its significance
  • The pieces with the most votes will be collected into the Time Capsule page

Uploading -

  • A visitor to the page can easily upload to our database a photograph, video, pdf document, or audio file that they believe to be important to the universe

Earth -

  • Users can view the heat map to see the areas of the globe most active on Crowd Capsule
  • They can also hover over the active points to view that area's submissions

The future of Crowd Capsule -

  • The winning digital files can be broadcast or encoded onto a device and sent out to space towards our galactic neighbors and also seen by our human users and viewed as our chronological story
  • We have a strong foundation for a scalable, immersive and captivating app
  • With more time and funding Crowd Capsule could be the resource that educates and informs visitors from outer space and engages our culture to collectively define our identity
