New spot-the-space-station programs, software to use 3D printing in space and apps to help astronauts take pictures of their home planet were among the technologies to come out of the 2013 contest.

The two-day space apps challenge was an international hackathon of sorts, soliciting mobile apps and technologies to aid space exploration and enrich life on Earth. More than 9,000 people from 83 cities around the world contributed to the 770 entries submitted between April 20 and 21, according to NASA.
