He must be serious about Mars: Elon Musk invests $2 billion in carbon fibers

(credit: SpaceX) SpaceX appears to be betting big on carbon fiber composites, which could increase the capacity of its future rockets to get people and supplies into space—and eventually to the surface of Mars. According to a report in Nikkei Asian Review , SpaceX has signed an agreement with Toray Carbon Fibers estimated to be worth $2 billion to $3 billion. The total price and delivery dates have yet to be finalized. It is not immediately clear exactly when, and in which launch vehicles, these lightweight composites will be employed by SpaceX. But the company is not alone in its interest—NASA and other aerospace companies have been experimenting with the materials because they have the potential to increase the amount of payload that can be carried by a rocket. They could also lower overall manufacturing cost. The scale of the deal seems telling, however. If the value of the deal as reported is correct, in the billions of dollars, it seems probable that the carbon fiber composites would be used in SpaceX’s proposed Mars Colonial Transporter rocket. This is the very large (but still under development) rocket the company plans to use to transport humans to Mars. SpaceX is already far along in the production of its Falcon Heavy rocket, which is based on the Falcon 9 core stage. The first stage of the Falcon 9 rocket, which SpaceX has successfully been landing this year, has tank walls and domes built from an aluminum lithium alloy.

Adobe almost does something amazing by accident

It seemed like an intriguing deal. An old version of Adobe Creative Suite—the 2005 vintage CS2, to be precise—became freely downloadable from Adobe, with nothing more than a free-to-create Adobe ID required from users. Although basically useless for Mac users, as CS2 is only available for PowerPC, for Windows users this is a powerful, if not quite cutting edge, suite of graphics apps. This looked like a clever move from Adobe. Photoshop is widely held to be one of the most routinely pirated applications there is. In making an old but still servicable version of the software it appeared that Adobe was offering a good alternative to piracy: instead of using a knock-off copy of CS6, just use CS2. A free CS2 would also go some way toward starving alternative applications of oxygen. Given the choice between a free copy of CS2 and downloading, say, the GIMP, one imagines that many users would plump for the commercial application. It’s more of a known quantity, with a more polished user interface. And Photoshop is, frankly, the gold standard of bitmap image editing. Even an older version has a prestige that GIMP doesn’t. This is not to say that CS2 is necessarily superior to the GIMP; it may or may not be. It doesn’t really matter; Photoshop has a reputation and respect that the GIMP doesn’t have, and even if some might argue that it was undeserved, it influences the decisions users make.
