With Air Force Office of Scientific Research funding, researchers led by Dr. Paulo Lozano at Massachusetts Institute of Technology are considering the advantages of electric propulsion over more traditional chemical rocketry. As a result, they have discovered "ionic liquid ion sources" which are the core elements of the mini-thruster.
In addition to the benefits anticipated for small satellites, the technology may have applicability in completely different areas.
"Fast-moving ions coming out from the mini-thrusters can be used to etch semiconductors to create patterns in the nanometer scale, to fabricate computer chips or small mechanical devices," said Lozano.
The team is interested in the properties that allow advances in travel between different orbits in space and the ability for spacecraft to self-destruct upon controlled re-entry, therefore preventing the creation of additional space debris.
Lozano predicts that he will have a mini-thruster prototype developed in about four or five months and he expects the technology to become a reality in the next two years. He plans to begin measuring the velocity of the ions and their energy as soon as the prototype is ready to determine the thrust and efficiency of the engine. Later this year, the team will begin looking at how to integrate mini-thrusters to flight hardware.
The Air Force Office of Scientific Research, located in Arlington, Virginia, continues to expand the horizon of scientific knowledge through its leadership and management of the Air Force's basic research program. As a vital component of the Air Force Research Laboratory, AFOSR's mission is to discover, shape and champion basic science that profoundly impacts the future Air Force.

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...

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...
