Aerospace engineers from MIT have developed a laser sensing technique that can decipher not only where but what kind of space junk may be passing overhead. For example, the technique, called laser polarimetry, may be used to discern whether a piece of debris is bare metal or covered with paint. The difference, the engineers say, could help determine an object’s mass, momentum, and potential for destruction.

Researchers from Tohoku University have been trying to find out how the plasma flow is influenced by its environment via laboratory experiments. And in doing so, have made headway on research towards creating an electrodeless plasma thruster used to propel spacecraft.The universe is made up of plasma - a gas so hot that its particles are electrically charged. This makes it easily influenced by magnetic fields and forces, which can lead to complex...

A new and powerful Fading Simulation option has been added toIZT's C3040Satellite Link Emulator. The Multipath Fading Simulator allows for precise modelling reflections of the signals on terrain, fixed and moving objects, both in satellite and terrestrial communication networks.The IZT C3040 Satellite Link Emulator is a cost-effective, time-saving solution for satellite and aircraft RF link testing.

Our Cold War history is now offering scientists a chance to better understand the complex space system that surrounds us. Space weather-which can include changes in Earth's magnetic environment-are usually triggered by the sun's activity, but recently declassified data on high-altitude nuclear explosion tests have provided a look at the mechansisms that set off perturbations in that magnetic system.

Hi-rel connector and SMT board hardware manufacturer, Harwin, has announced that increased investment in its Salem, New Hampshire cable assembly facility is winning new business in the demanding and highly specialised space and avionics sector. At its US site, Harwin’s cabling capabilities include building to customer datasheet, prototyping, and electrical and mechanical testing of both cable and wire harnesses and coaxial cable assemblies.

Rohde & Schwarz is extending the functional range of its R&S SMW200A vector signal generator to include the DVB-S2 satellite standard and its extension DVB-S2X. With a new software option it provides a simple solution for testing components, devices and satellites that support these standards.

After some work and research into cycloidal gearing, CEO of Vert Rotors UK Olly Dmitriev decided that the principles of this technology could be applied to a compressor.The new type of oil-free screw compressor developed and patented by Vert Rotors has proved to be 35% more energy efficient than dry oil-free machines. The main reason for this energy saving is that there is no stator in the design, which is common in rotary twin shaft compressors ...

The winning design in the International Space Station (I.S.S.) Design Challenge has been 3D-printed in space. The winning design, a satellite-launching device, is now in orbit and may one day be used by astronauts for a variety of missions. The news was announced by Mouser Electronics and Grant Imahara.

The space sector and the enabling technologies produced represent a key driving force in innovation. In cooperation with new sectors from different industries (including non-space sectors), extraordinary business models and commercialisation concepts are emerging which hold great potential to revolutionise the entire value chain and open up new markets.

Provider of semiconductor solutions,Microsemi, has extended its congratulations to Iridium Communications, Thales Alenia Space, SpaceX and project subcontractors on the successful launch of the first ten Iridium NEXT satellites. Iridium NEXT is Iridium’s next-gen satellite constellation, replacing and enhancing its existing network of low-Earth orbit satellites spanning the globe. The project is leveraging more than 200,000 Microsemi device...
