Permanence & Wayfinding

This is something that we don't do that much anymore in our built environment, that is to make a permanent mark for something that may only have temporary value.  Here we have a north arrow set into the concrete sidewalk in downtown Boston.  Why would someone do this?  It is not a part of a larger mural or other work of art, it is simply an arrow and the letter "N".  But somehow the person funding the building project decided to spend some extra money to have this laid into the sidewalk and probably had no return on the investment.  That must've been a hell of a sell by the architect if it was in fact the architects idea.  I have clients that would never spend money on anything so seemingly frivolous.  But then, we all value things differently don't we?  I would spend the extra money to lay this in the sidewalk, yet the Freedom Trail Foundation has laid out their red line here in paint rather than the brick that they have done in other parts of it.  

Something to be excited about

SpaceX is one of the few things that I’m really excited about at the moment in relation to crewed spaceflight. I love the ISS and Shuttle, but due to the upcoming retirement of the STS that love is bittersweet. Ares/Orion/Altair is in development, but its unclear how soon that will become a reality since they are at the mercy of a political and budgetary system that are in transition at the moment.

SpaceX is a private company that is working to develop a family of low to medium lift rockets for commercial use. The Falcon 1 development had a few snags in the form of 3 consecutive launch failures, but is still riding the high of the fourth and successful launch. They’re pushing ahead on the larger Falcon 9 booster which can carry larger payloads and the Dragon capsule. Dragon has several uses, among them is rendezvousing with the ISS for resupply, cargo return, and potentially crew transfer/lifeboat capability.

The test shown above is for the orbital thruster design. It’s conducted in a vacuum chamber that SpaceX custom-built which is why you can’t actually see any exhaust from the combustion. The only way you can tell that anything is actually happening in there is because of the way the engine bell glows red hot. Awesome.
