Tim Peake completes London Marathon from orbit

British astronaut Tim Peake has successfully completed the London Marathon whilst orbiting 400 km (248 miles) above the Earth aboard the International Space Station. Peake is only the second astronaut to complete a Marathon in space, alongside NASA Astronaut Sunita Williams, who took part in the Boston Marathon from the ISS back in 2007.Read More

Planes, ships and ground stations working together to study pollution

Next week, an international effort between NASA and the Republic of Korea's National Institute of Environmental Research (NIER) will see the two bodies working together on an ambitious, six-week set of observations designed to improve our understanding of air pollution. The project will include the use of three planes housing 37 different instruments, and more than 300 ground sites, working together to gather data that help in the development of new solution to combat poor air quality across the globe.Read More

Connected Conservation: Using drones, sensors and Wi-Fi to stop poachers

By their very nature, wildlife reserves are generally located in remote areas beyond the reach of typical communications technologies. This is good news if you're a poacher trying to infiltrate area, and bad news for patrol teams working to keep them out. But a new initiative is looking to tip things in the good guys' favor by fitting out an African nature reserve with high-tech gear, such as seismic sensors and infrared drones, all of which is networked to keep tabs on who exactly is going in and out of the park.Read More

NASA taps Aerojet Rocketdyne for new space propulsion system

In anticipation of future deep-space missions, NASA has awarded a US$67 million, 36-month contract to Redmond, Washington-based Aerojet Rocketdyne to design and develop an Advanced Electric Propulsion System (AEPS). Based on previous ion thrusters like prototype NEXT and the Dawn mission to the asteroid Ceres, the new propulsion system could used to supply a future manned Mars mission.Read More

Laser-fueled vortex creates nanotube forest

While small in size, carbon nanotubes can be mighty in their applications. But manipulating carbon nanotubes can be tricky, considering that their diameter is about 50,000 times smaller than a human hair. Researchers at Purdue University have just come up with a way to force carbon nanotubes to get in line – literally – by using electrical pulses and a vortex created by laser light.Read More
