ARCA is one of the teams competing for the Google Lunar X Prize. ARCA is a Romanian team that is set to launch a satellite for Bulgaria sometime in 2013 using their HAAS 2 single stage rocket, the same rocket they will use to launch their lunar explorer. There are currently 25 teams competing for the Lunar X Prize, six of whom are American. Most of the teams have made enough progress to still be in the running, but the clock is ticking and although no team has set a solid launch date (that I am aware of) several are touting launches within the next few years. My current favorite lander design, although admittedly mostly for its unique look, is the Chilean team's named: Dandelion.
