The Caltech Space Challenge is a 5-Day International Student Space Mission Design Competition 

The Caltech Space Challenge brings 32 talented and highly-motivated students to the Caltech campus to participate in a week-long space mission design competition. The participants are split into two teams and both teams work under the mentorship of experts from industry, NASA and academia to design their mission concept from scratch to final proposal. The Challenge is a unique opportunity for young and enthusiastic students to build technical and teamwork skills, interact with world-renowed experts in space exploration and connect to like-minded peers from all around the world.

The next edition of the Caltech Space Challenge will take place from March 24 to March 29, 2019.
