    Some Phoenix questions and answers
    I did a short interview about Phoenix for a new Web outlet called "TalkingHeadTV" yesterday, and there are three clips up on YouTube here, here, and here. Check them out! I'll probably get back to weekly Ustream webcasts next week -- stay tuned... More»

    I've spent a chunk of today working on figuring out what Phoenix has been up to during my absence. Mark Lemmon's pages have been really helpful, especially now that he has added pithy little sol-by-sol summaries to his directory page. Here's the... More»

    I'm back from vacation and slowly getting back up to speed, so it's a good time to check in on what's going on with our trusty robots around the solar system. Before I do that I want to give a big thanks to Jim and James for their contributions. ... More»
