SpaceX Vision - In this video Elon Musk talks about his plans for SpaceX and how his plans for the company integrate with his over arching vision for his other ventures (Tesla, SolarCity). SpaceX continues to make rapid progress towards the company’s goal of fully reusable launch and space vehicles, and has inspired several other companies build upon SpaceX’ promise of low cost space access (e.g. MarsOne).

Hear how Musk plans to send millions of people to colonize Mars, as Michelle Fields talks to the tech innovator about the future of space exploration, scientific innovation and doing business in California during a recession.

Hills and other topology can have interesting and complex effects on a flowfield. With the FAITH experiment, NASA has been investigating an axisymmetric model hill using a combination of experimental methods. The video above shows flow visualization over the hill in a water channel using dye injection both upstream and downstream of the model. They’ve also done wind tunnel tests with oil-flow visualization, particle-image velocimetry, pressure sensitive paint and other measurement techniques. There are nice photos of some of these by Rob Bulmahn. By combining qualitative and quantitative flow measurement techniques, the researchers are able to capture many different aspects of the flow, which can then be shared and compared with other groups’ works.
