Actually there are three JPL-funded early prototype drills, intended to go down 2m several times on the 2007 "smart lander" mission. Plus Johnson Space Center and an oil exploration company are working on another design. And a Canadian consortium in Ontario has another prototype. My project isn't competing with these, we're looking at how to do the automated monitoring, troubleshooting and control of whichever drill gets selected...
