Innovative electronic design & development for space

Innovative electronic design & development for space
The efficient interaction of electronic components and their environment plays an important role in development of products for space. Art of Technology supports companies and universities optimising electronic designs to save both size and weight. Written by Paul Sphikas, Sales & Marketing Manager, Art of Technology AG

Defunct satellites are taking up space in space

Defunct satellites are taking up space in space
  Space is becoming ever more cluttered with defunct satellites, spent rocket boosters and sundry stray pieces after the first satellite was launched almost 60 years ago.

Researchers develop first image of a black hole

Researchers develop first image of a black hole
A team of researchers from around the world is getting ready to create what might be the first image of a black hole. The project is the result of collaboration between teams manning radio receivers around the world and a team at MIT that will assemble the data from the other teams and hopefully create an image. The project has been ongoing for approximately 20 years as project members have sought to piece together what has now become known as the Event Horizon Telescope (EHT).

First planet-induced stellar pulsations observed

First planet-induced stellar pulsations observed
For the first time, astronomers from MIT and elsewhere have observed a star pulsing in response to its orbiting planet. The star, which goes by the name HAT-P-2, is about 400 light years from Earth and is circled by a gas giant measuring eight times the mass of Jupiter — one of the most massive exoplanets known today. The planet, named HAT-P-2b, tracks its star in a highly eccentric orbit, flying extremely close to and around the star, then hurtling far out before eventually circling back around.

Lasers could give space research its 'broadband' moment

Lasers could give space research its 'broadband' moment
Thought your Internet speeds were slow? Try being a space scientist for a day. The vast distances involved will throttle data rates to a trickle. You're lucky if a spacecraft can send more than a few Mbps—a pittance even by dial-up standards. But we might be on the cusp of a change. Just as going from dial-up to broadband revolutionised the Internet and made high-resolution photos and streaming video a given, NASA may be ready to undergo a similar "broadband" moment in coming years.

NASA and MIT develop quantum-dot spectrometer

NASA and MIT develop quantum-dot spectrometer
A NASA technologist has teamed with the inventor of a nanotechnology that could transform the way space scientists build spectrometers, the all-important device used by virtually all scientific disciplines to measure the properties of light emanating from astronomical objects, including Earth itself.

Database could help find signs of new exoplanets

Database could help find signs of new exoplanets
The search for planets beyond our solar system is about to gain some new recruits. Today, a team that includes MIT and is led by the Carnegie Institution for Science has released the largest collection of observations made with a technique called radial velocity, to be used for hunting exoplanets. The huge dataset, taken over two decades by the W.M. Keck Observatory in Hawaii, is now available to the public, along with an open-source software package to process the data and an online tutorial.

Increasing the sensitivity of gravitational wave detectors

Increasing the sensitivity of gravitational wave detectors
Nearly one year ago today, the LIGO Collaboration announced the detection of gravitational waves, once again confirming Einstein's theory of General Relativity. This important discovery by the Advanced Laser Interferometer Gravitational-Wave Observatory (aLIGO) has spurred great interest in improving these advanced optical detectors. The mission of gravitational wave scientists worldwide is to make gravitational wave detection a routine occurrence.

EU activates its Galileo satellite navigation system

EU activates its Galileo satellite navigation system
The European Union activated its Galileo satellite navigation system in December 2016. The EU is dedicated to setting this system apart from other navigation systems such as GPS – the US counterpart of Galileo. Researchers from the Department of Electrical Engineering at KU Leuven have now risen to this challenge as well: they designed authentication features that will make it even more difficult to send out false Galileo signals.
