I am working on a presentation introducing JIRA. I went up on the Atlassian website to learn more about their company. As Atlassian isn't as well-known as, say, Microsoft, I wanted to share some cool facts about their company and user base. Found this page of stats: https://www.atlassian.com/company
It says "2 Planets". That's intriguing but I know if I put that in my presentation, someone is going to ask me which planets and why. I assume it's mars but I'd like to know what - is it a Mars Rover participating in HIpChats or a space probe reporting asteroids as JIRA issues?
NASA makes heavy use of Atlassian stuff, and your assumption that the reference is to Mars is spot on - specifically, it's related to Curiosity. See http://blogs.atlassian.com/2012/05/nasa-atlassian-development-tools/
