San Francisco, CA (Mar. 28, 2012 – Citizens in Space PR) — Citizen scientists and hardware hackers are being challenged to develop payloads for commercial reusable suborbital spacecraft during the International Space Apps Challenge, a NASA-sponsored event that takes place worldwide and aboard the International Space Station on April 21-22.
The International Space Apps Challenge is a two-day “codeathon” which invites developers, hobbyists, and hackers around the world to work on a variety of hardware and software challenges. Citizens in Space, a project of the United States Rocket Academy, is challenging participants to develop suborbital science payloads as part of the event.
Successful payloads may fly into space aboard one of the commercial reusable spacecraft that are now under development by companies such as XCOR Aerospace. XCOR Aerospace is building the Lynx, a two-seat rocketship that is expected to make its first flight before the end of this year.
