If there wasn't life on Mars before, there might be now. Before NASA sent Curiosity to Mars, it was thoroughly cleaned of all traces of contaminants. But swabs of rover's surfaces taken before it was sent to Mars have revealed 377 different strains of bacteria that potentially could have made the trip. Some of them may have even survived.
A study that identified 377 strains found that a surprising number resist extreme temperatures and damage caused by ultraviolet-C radiation, the most potentially harmful type. The results, presented today at the annual meeting of the American Society for Microbiology, are a first step towards elucidating how certain bacteria might survive decontamination and space flight.
From Our City, Our Story, the story of a Rockford, Illinois gear factory that made all of the gears for the Mars Curiosity rover.
What might be more remarkable than creating crucial equipment destined for Mars? For a second time? Well, creating a thriving motivated company culture with a team of career employees -- the kind who lie in bed at night thinking, "what can I do in the morning when I get there?" The kind who take on responsibility, impose their own high standards and like Amy Sovina, have the "mindset something I touched is now on the surface of Mars."
I would love to have seen a live feed of these gear shop employees watching the landing.
'There's a popular belief that projects like this are going to be very advanced but there are things that mitigate against that. These designs were proposed in 2004, and you don't get to propose one specification and then go off and develop something else. 2MP with 8GB of flash [memory] didn't sound too bad in 2004. But it doesn't compare well to what you get in an iPhone today.'
The cameras were also supposed to be outfitted with zoom lenses but that part of the project was scrapped.
The rest of you can have your Olympics, but the early August event I'm most looking forward to is the arrival on Mars of the Curiosity rover. But NASA has had someproblems in the past delivering payloads to Mars, so this is going to be somewhat of a nail-biter. If you haven't seen it, Curiosity's Seven Minutes of Terror is well worth watching to see the logistical challenge of getting the rover down to the surface.
Curiosity will hopefully land on the surface on Aug 6 at about 1:30 am ET.
