  • The Daily Countdown

    I will do my best to give a rundown of the top 3 space/science news stories of the day, with some nugget at the end. This is the first of those posts.

    3… The morning saw the sad, sad news that attempts to revive Spirit – the first Mars Exploration Rover – were ending. But the cliche “led a long, full life” may never have been more appropriate. Spirit landed on January 4, 2004. It’s primary mission was scheduled to end 90 days later on April 3, 2004. However, the rover continued operating well past that deadline – even dragging one

  • Slipping the Surly Bonds of Earth

    Slipping the Surly Bonds of Earth. Scientists often debate the wisdom and value of sending humans into space. Images like this drive home the immensity and grandeur of the endeavor, irrespective of the arguments.

  • Brainstorm: Regular Content

    We want your input on types of regular content we could have on In conversations with Betül, Ariel, and others, we have a “starter” list of ideas:

    Brainstorm – Is this type of post a good idea for a regular feature? We could brainstorm on research, outreach, or science careers ideas

    Science Slam – A short video/podcast discussing some scientific topic

    Featured Scientist – A guest post or interview with a scientist

    Journal Club – We pick an article and discuss it, blog style

    Open Thread – Just a place to hang out and discuss…. whatever

    Mission Focus – Discuss a past/present/future/concept mission, once a

  • A Sample of One

    Shawn’s comment on yesterday’s word cloud posted by Betul inspired me to start thinking about a sample of one. It is remarkable that the only life in the universe we know about is here on Earth. You might expect there to be an abundance of life in the universe, or none at all, but not a sample of one. This is an interesting conversation in itself – but you may wonder why with a known sample of one, astrobiology is any different than biology for example, they both study the same sample of life. I think it breaks down

  • Astrobiology Primer

    Collaboration among scientists with expertise in various fields is a requirement for astrobiology’s breadth and interdisciplinarity. For example, it would not be unusual for experts in evolutionary biology, ecology, geochemistry and biochemistry to work together on an astrobiology research project. This blog is our attempt to bring this interdisciplinary and collaborative framework a step further, by proving a platform for scientists (and science enthusiasts) of any level to share their interest in astrobiology.

    To see how diverse astrobiology is, see the word cloud of Astrobiology Primer V1. Feel

  • How is this science blog different from most other science blogs?

    If we want to use this blog to create a community, what could be better than a community blog? Most science blogs – like most blogs in general – present the single voice of a single author. PaleBlueBlog will be different because it will be a group blog. We are assembling a team of diverse, science-savvy contributors who represent not only a range of expertise, but also a range of personal perspectives. As a consequence, we hope you will often see us disagree as we report and discuss the scientific discoveries of the day. What we share is a conviction
