A February 2021 news item covered work at the Polish Institute of Aviation on an alternative satellite propulsion system. The project was supported through the European Space Agency’s Polish Industry Incentive programme.
The GRACE project examined propellant options intended to improve handling and environmental characteristics compared with conventional hydrazine-based systems. The archive reported a 60-second engine test and research involving high-test hydrogen peroxide as an oxidiser.
An experimental firing is a development milestone, not proof that a propulsion system is ready for every mission. The original story highlighted Polish participation in spacecraft research. This edited version retains that context and avoids the original text’s ambiguous chemical explanation or a blanket claim that the fuel is harmless.
Ayming’s International Innovation Barometer 2022, covered on the old site in October 2021, described an uneven response to the pandemic. Some businesses accelerated new ways of working while others struggled to maintain research and development.
In March 2021, researchers at UC San Diego reported a device designed to perform a neural-network activation function directly in hardware. The work explored a way to reduce the circuitry and energy involved in that part of a network.
The February 2021 archive discussed geospatial intelligence, or GEOINT, through a policy viewpoint reported by C4ISRNET. The topic concerned information about locations and activity on Earth, including imagery and other geographically referenced data.
