The next big thing in space is really, really small
Going into space is now within your grasp. A tiny spacecraft being developed at Arizona State University is breaking the barrier of launch cost, making the price of conducting a space mission radically cheaper.
Satellites provide missing information on climate change
An international team of scientists led by Prof. Daniel Rosenfeld from The Hebrew University of Jerusalem found a way to measure missing critical information needed to quantify manmade responsibility for climate change. In a paper published in the journal Proceedings of the National Academy of Sciences, the authors describe a new way to determine both cloud-base updraft speeds and quantify the aerosol particles' ability to create cloud droplets.
F1 technology could improve fuel efficiency
Formula 1 technology could soon make family cars lighter, improve fuel efficiency and help plug-in vehicles go further - after an innovative research project won a share of a £38.2m government prize. The project is one of more than 130 car manufacturers, technology companies and research centres across the country to have won a share of the money, announced in the Budget, which will create hi-tech jobs and help Britain become a global leade...
ICON to be launched in the summer 2017
NASA's latest space weather research satellite, the Ionospheric Connection Explorer, is on course for a summer 2017 launch after UC Berkeley scientists and their colleagues shipped its four instruments to Utah for testing, prior to being packed into the final satellite. The ICON mission, led by UC Berkeley's Space Sciences Laboratory with the help of scientists and engineers from around the world, will add one more satellite to NASA's fleet of 26...
First prototype of all-in-one 3D-printed space antenna
A prototype 3D-printed antenna being put to work in ESA's Compact Antenna Test Facility, a shielded chamber for antenna and radio-frequency testing. "This is the Agency's first 3D-printed dual-reflector antenna," explains engineer Maarten van der Vorst, who designed it. "Incorporating a corrugated feedhorn and two reflectors, it has been printed all-in-one in a polymer, then plated with copper to meet its radio-frequency (RF) performance requirem...
Aircraft tracking system could aid disaster relief efforts
A tracking system called HYPERION based on eye-safe lasers could enable aircraft, UAVs and even orbiting satellites to transmit vital data to ground stations more securely, quickly and efficiently. The development of HYPERION has been pioneered by a joint team through Innovate UK's HITEA programme: the University of Oxford with funding from the EPSRC, and Airbus Group Innovations with Innovate UK support.
Flexible high-speed data networking provided for space applications
Microsemi Corporation and STAR-Dundee have announced their collaboration to provide SpaceWire and SpaceFibre network technology using Microsemi's RTG4(TM) high-speed signal processing radiation-tolerant FPGAs. STAR-Dundee specialises in supporting users and developers of SpaceWire and SpaceFibre, which are data-handling networks for onboard satellites and spacecraft.
New satellite data centre hosted at Portsmouth
The University of Portsmouth is to host a centre of excellence for satellite data, which will promote economic growth in the UK’s space sector. The centre will allow the south coast business community to tap into satellite technology that could improve their products and services, for example, developing technology to help robot submarines use live satellite data to inform their route through the ocean – similar to drivers using live ...
Fuel cells powering inner-city vehicles
Inner-city deliveries in Austria may soon be powered by pollution-free fuel cell technology that is also being explored by ESA for satellites and robotic missions to Mars. Austrian transport specialist HET Engineering has designed a quiet, zero-emission vehicle for sensitive traffic areas. With technical assistance from the DLR German Aerospace Center, the company's Citylog EMF vehicles will be small enough to navigate narrow and congested street...
Increasing ESD protection and signal processing performance
The portfolio of radiation tolerant multiplexers from Intersil Corporation has been expanded with the release of two new, single supply 5V devices. The 16-channel ISL71830SEH and 32-channel ISL71831SEH multiplexers join Intersil’s 30V multiplexers, which have been onboard many satellite and space exploration missions, including NASA’s Orion spacecraft flight test.
