Life on Mars? Why Not?
Guillaume Filion writes "IEEE spectrum has an interesting article about a new probe sent to Mars searching for life: 'Recent missions to Mars have focused on the search for water, past or present, as a surrogate for life itself. But now a British-led team is working to renew the search for life directly, fueled by doubts about the equipment that prompted NASA to declare Mars a dead world some 26 years ago.'"
What difference does it make if there's some bacteria or whatever on Mars? How does this affect life on Earth? I'm all for space exploration and pure science.. but I'd spend my dollars on getting humans to Mars rather than finding out whether there are bacteria there.
