We'll soon know what kinds of crops we can grow on Mars! Bonus, the fruits will be already freeze-dried!

It's not really the media's fault. The Phoenix panel came out of the gate with a story from Hecht about how he called a friend working in Antarctica and told her that they now knew what they needed to know about how to grow stuff in Martian soil, because they knew what "nutrients" were there. And then they seemed confused when the reporters asked, okay, what kind of life are you talking about? Viruses? Bacteria? Multicellular stuff? Plants? And they weren't prepared to answer. Finally they said the pH was compatible with asparagus, turnips, and green beans, and there was nothing incompatible about the soil. But they'd started talking about life, so the reporters were asking, what about the trace elements? What about organics? And of course they couldn't answer those questions, because they couldn't do those tests.
