Danish astronaut to control earthbound rover from ISS

By - August 30, 2015 4 Pictures

Working outside in space is a tall order. The environment is hostile, even the smallest job takes hours instead of minutes, and everything has to be done in either bulky suits or through robotic arms. It's a challenge that will become even more difficult when future astronauts are controlling robotic rovers from orbit, so ESA is getting in a bit of practice. Next month Danish astronaut Andreas Mogensen will take control of a rover in the Netherlands while orbiting the Earth aboard the International Space Station.

Gremlins in the works: DARPA's vision for future air operations

By - August 30, 2015

The United States boasts some of the most advanced multi-mission combat aircraft in the world, but this can be a liability as well as an asset. True, each aircraft can outperform an entire squadron of a few decades ago, but they're also very expensive, incredibly complex, and not exactly expendable. For these reasons DARPA has launched the Gremlins program, which aims to develop swarms of cheaper, smarter aircraft that can be deployed and collected in midair.

Despite the abundance of portable audio products, the choices for enjoying music while riding a bicycle are more limited. Headphones and earphones aren't ideal for those needing situational awareness, and most speakers aren't created with bicycle-mounting in mind. Scosche's recently-announced Bluetooth wireless speaker, the BoomBottle+, is designed to be rugged, loud, and conveniently-shaped to fit in most bicycle bottle cages.

NASA tests 3D-printed turbopump

By - August 30, 2015 3 Pictures

NASA has previously tested simple 3D-printed rocket components, such as combustion chambers and fuel injectors, but if the technique is to be practical, it has to cope with more complex items. Case in point is this 3D-printed rocket engine turbopump. Successfully built and tested at NASA's Marshall Space Flight Center in Huntsville, Alabama, the turbopump is described as "one of the most complex, 3D-printed rocket engine parts ever made."

Planetoid a billion miles beyond Pluto selected as New Horizons' next destination

By - August 30, 2015 3 Pictures

New Horizons isn't going to get much of a rest. Following on from its historic flyby of Pluto on July 14, NASA has selected the next potential destination for the unmanned spacecraft – a planetoid called 2014 MU69 that lies a billion miles beyond Pluto's orbit. The space probe will take over three years to reach this frozen remnant of the Solar System's earliest years.
