An image from the NASA website depicts Briton Piers J Sellars working on the ISS (International Space Station) during an EVA (Extra Vehicular Activity, more commonly known as a space-walk). Sellars had some difficulty during his second EVA yesterday, when his emergency jet thruster back-pack came loose from its tether. Fortunately his colleague Mike Fossum was on hand to secure it in place.
A close examination of Sellars suit reveals a graphic of an astronaut, drawn in the style of Da Vinci’s Vitruvian Man. I love this kind of witty design thinking. Its also an appropriate symbol – The multipurpose logistics module being delivered to the ISS is called Leonardo.
