Researchers from ETH Zurich (Department of Information Technology and Electrical Engineering) and the ETH spin-off Celeroton have developed an ultra-fast magnetically levitated electric motor for reaction wheels. The high speed of rotation allows intensive miniaturisation of the drive system, making it attractive for use in small satellites.

Since Sputnik 1 was launched by the Russians in 1957, more than 50 countries have joined the race to launch satellites into orbit from low-earth to geosynchronous orbit (260 to 22,240 miles from earth). Of the more than 3,500 satellites in earth’s orbit, about 1/3 are active while the rest are no longer operating. The business of launching satellites is evolving, however, and the numbers of operational satellites are set to increase by thou...

The cost of solar power is beginning to reach price parity with cheaper fossil fuel-based electricity in many parts of the world, yet the clean energy source still accounts for just slightly more than 1% of the world’s electricity mix.Solar, or photovoltaic (PV), cells, which convert sunlight into electrical energy, have a large role to play in boosting solar power generation globally.

A team of small, shoebox-sized satellites, flying in formation around the Earth, could estimate the planet’s reflected energy with twice the accuracy of traditional monolith satellites, according to an MIT-led study published online in Acta Astronautica. If done right, such satellite swarms could also be cheaper to build, launch and maintain.

The BARREL team is at Esrange Space Center near Kiruna, Sweden, launching a series of six scientific payloads on miniature scientific balloons. The BARREL team launched the first balloon of this campaign – the fourth for BARREL – on Aug. 13, 2016. The NASA-funded BARREL – which stands for Balloon Array for Radiation-belt Relativistic Electron Losses – primarily measures X-rays in Earth’s atmosphere near the North and...

A global provider of engineered electronics for performance critical applications,TT Electronics has announced the market introduction of its HCC100x series of radiation tolerant optocouplers. The devices are ideal for the isolation of electrical circuits within high-radiation deep spaceflight applications, including satellites, launch vehicles, space craft, and planetary rovers.

The TSR 6DXC Shock Recorder that incorporates built-in sensors in a small, rugged system that makes high shock and vibration data collection easier than ever, has been introduced by DTS. The self-powered system is ideal for unattended monitoring in blast and multi-event impacts. The TSR 6DXC can capture up to 2,000 transient shock events or run as a continuous data recorder for seconds to days.

Microsemi has announced the RTG4 development kit with its recently announced RTG4 PROTO FPGAs. Hailed as the industry’s first radiation-tolerant FPGA kit providing space designers a comprehensive evaluation and design platform, it is suited for the development of applications such as data transmission, serial connectivity, bus interface and high speed designs, using the company’s RTG4 radiation-tolerant high-speed FPGAs.

Metal 3D printing technology has been developed to help space systems reduce time and costs.

Intersil has announced what it claims to be the industry’s first radiation tolerant 36V in-amp (instrumentation amplifier) featuring an integrated differential ADC driver. The high performance ISL70617SEH differential input, rail-to-rail output in-amp delivers the industry’s highest signal processing performance for low-level sensor telemetry data critical to communication satellites.
