Here's a bit of news that I find very exciting- NASA's Mars Curiosity Rover detected carbon-based molecules in sedimentary rocks on Mars and seasonal methane variations in the Martian atmosphere. While this doesn't mean that NASA discovered life on Mars, it does mean that, at least at one time, life was possible on Mars. With the discovery of these tantalizing hints that life may have existed on Mars, the Mars 2020 Rover mission takes on a renewed urgency.
I periodically blog about Mars- in fact, Mars came up as a subject of last month's Secret Science Club lecture. I feel that humanity eventually needs to get it's ass together and colonize other planets, or put succinctly:
Learning more about the red planet is crucial for humanity's long-term goals, especially in light of stupid geopolitical events, which are increasingly looking like an explanation for the Fermi Paradox.
