MARS stories

If there's life on Mars right now, it's either really good at hiding from our robots, or it's too small to be able to wave at us. In either case, an effective way of finding it might be through gene sequencing, which is why scientists want to send a DNA sequencer on Mars. It's called "the search for extraterrestrial genomes," which I have abbreviated to "SEx GNomes."
In all the fuss about Curiosity, the new kid on the Martian block, it's been easy to forget about the Opportunity rover, and the work it has been doing for eight long years. Well, it seems Opportunity has made an interesting discovery worth looking at — small, round spherules which scientists are calling "blueberries."
