This annual contest is for all students at up to 12th grade from anywhere in the world. Individuals, small teams of two to five, and large teams of six to twelve are judged separately. The contest was originally run by NASA Ames Research Center from 1994-2018, jointly sponsored by NSS for several years, and is now run exclusively by NSS. Several thousand students take part each year.
International Space Settlement Design Competition
This annual contest puts high school students in the shoes of aerospace industry engineers designing a city in space that will house over 10,000 people. Student engineers demonstrate creativity, technical competence, management skills, environmental knowledge, space, teamwork, and presentation techniques to conquer the problems inherent in siting and designing a Space Settlement (Space Colony).
“Live in a Healthy Space” Design Competition 
The National Space Society’s “Live in a Healthy Space” Design Competition challenges middle and high school students (ages 12-18) to design one specific component of a space settlement – an Agricultural Module (or area). Deadline is November 30.
spUN Student Debates at ISDC 
The National Space Society’s SpacEdge Education will be hosting virtual student debate tournaments to be held in late May/early June 2021. These spUN (Space Policy and UNiversalization) Debates will be offered at the middle school/high school level. The spUN Debates offer people around the globe an opportunity to contemplate the policies that will make their mark in space settlement. The development of space policy, the players, the representation of an inclusion of people, the military aspect, and the implications of space policy and development on the governance of Earth are topics that are under consideration for the spUN Debates.

Jim Baen Memorial Writing Contest
The Jim Baen Memorial Writing Contest has been co-sponsored by NSS and Baen Books since 2007. Science fiction writers who create positive stories about man’s future in space are rewarded with professional publication, NSS membership, and an award presented each year at the ISDC. Winning entries aren’t pulp tales about galactic empires or alien abductions, but serious near future stories about the sacrifice, heroics, adventure and discovery with our expansion into the solar system. Note that the contest opens on October 1st of each year, and is closed for submissions on February 1st of the following year.
