The cutting-edge research of Earth to Sky Calculus is 100% crowd-funded. Would you like to sponsor a research flight? The cost is $500. In return for your donation, we will fly a card or other item to the stratosphere and photograph it at the edge of space. After the flight, you will receive complete HD video of the flight, from launch to landing, as well as still-frame highlights that you can use to make greeting cards and prints for framing.
