Hasta La Gadget!

After a series of successful tests on the Skylon spaceplane’s SABRE engine, the UK government has decided to invest another £60 million to continue developing it. The scramjet-based tech could pave the way for cheaper space travel, since it carries little oxygen on board and can maneuver like an airplane before rockets kick it into orbit. Earlier, a key component that chills air from 1,830 to minus 302 degrees Fahrenheit in 1/100th of a second passed its trials with flying colors. That means the project team can move to the next phase: building and ground testing a prototype SABRE engine. Though billions of pounds more would be needed to eventually develop a Skylon vehicle, a European Space Agency spokesman thinks it would be worth it, saying “we have something here that is really unique.” Let’s hope they can match recent scramjet success stateside and avoid the whole crashing part.

Levitating objects with sound waves isn’t anything new, but a team from Switzerland has taken it to the next level by rotating and moving objects as they float. In fact, the researchers were able to manipulate a number of objects mid-air, including water droplets, inserting DNA into cells and mixing up a little instant coffee. If you’re wondering how intense sound waves need to be to get things moving (at this level, at least) then 160 decibels is the starting point. If that sounds ear-splittingly loud, that’s because it is. But, by using frequencies typically out of the human audible range (24 kHz), no ears were at risk. The movement itself is controlled by a grid of sound-emitting squares. Once the object was in the air, it could be moved around by lowering the volume on one grid point, and increasing it on the next. For now, the science is only able to lift tiny objects, but the same team claims that it’ll will soon show similar work using steel balls. Could we use this to get our (sonic) hoverboard? We’re not calling that just yet.

ISS Flight Engineers Chris Cassidy and Luca Parmitano are set to commence a spacewalk on the ISS today starting at 8:10 ET. The pair will undertake the final installation of bypass jumpers, providing essential power redundancy to critical components. Other tasks to be completed on the walk include replacing a video camera, relocating wireless television kit and performing vital checks on component door covers. This will be the fifth spacewalk performed on the ISS this year, and the 171st in support of the station overall. You can watch the preliminaries right now, or head back at 8:10 to catch the action.

Update: As those watching will be aware, the spacewalk wound up being cut considerably short due to a water leak in astronaut Luca Parmitano’s helmet that required him to be assisted back inside the space station.

Opinions about Bose’s consumer audio products aside, there’s no discrediting the extensive contributions its founder added to the world of amplified sound. On that note, we’re saddened to report that its Founder, Chairman and Technical Director, Dr. Amar Gopal Bose, has died — this, just two years after donating a majority of Bose Corporation shares to MIT. According to MIT News, after earning degrees in Electric Engineering at the college, he taught there from 1956 until 2001. While teaching, he studied physical and psycho-acoustics, which resulted in his patents in “acoustics, electronics, nonlinear systems and communication theory.” In 1964 he founded the company, Bose Corporation, that would bring us the well-known noise-cancelling headphones and audio systems that many have come cherish. An official statement from Bose Corp. and more info about the man himself can be found at the source links.
