Today sees ESAs first ever microsatellite complete three years of successful operations. The size of a large television set, Proba was launched to demonstrate new technologies for future European spacecraft, but continues to provide fantastic images of Earth.
"It is amazing what we have got out of Proba, our first micro-satellite," says Frederic Teston, ESAs Proba Project Manager. "The mission has successfully demonstrated a number of sophisticated technologies in addition to new approaches in spacecraft construction and operations. "It has 100% lived-up to its full name of Project for On-Board Autonomy – for every day of the last three years the spacecraft performed onboard such functions as steering, navigation, target fly-by estimation and image capture. These are all functions that have to be handled from the ground for larger spacecraft. "We just provide the latitude, longitude and altitude of a target site, and Proba will handle the rest. The onboard computer steers the spacecraft to the correct position, tilts it correctly, shoots and delivers the image."
The thinking underpinning Proba is that tightly focused missions can be delivered in a short time frame useful to scientists - if the time taken from the original concept to launch and operation can be greatly reduced.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
