When Atlassian says their software is running on two planets, which software and is it Mars?

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/
