Exploiting Signals Broadcast by Multi-Constellation LEO Satellites
Researchers have developed an algorithm that can “eavesdrop” on any signal from a satellite and use it to locate any point on Earth, much like GPS. The study represents the first time an algorithm was able to exploit signals broadcast by multi-constellation low-Earth orbit satellites.
Briefs: Materials
To further shrink electronic devices and to lower energy consumption, the semiconductor industry is interested in using 2D materials but manufacturers need a quick and accurate method for detecting defects in these materials to determine if the material is suitable for device manufacture.

Innovators at NASA Johnson Space Center have developed a carbon fiber reinforced polymer (CFRP) sleeve, that, when fitted over a cylindrical Li-ion battery cell, can prevent cell-to-cell propagation by containing a thermal runaway (TR) event to the originating cell.
Briefs: Manufacturing & Prototyping
Engineers have made progress toward lithium-metal batteries that charge as fast as an hour. This fast charging is thanks to lithium metal crystals that can be seeded and grown — quickly and uniformly — on a surprising surface.
Briefs: Energy
Researchers continue to refine the process to improve electrochemical performance. The goal is to balance the benefits and drawbacks of the thicker electrode: It has the potential for higher energy loading and is easy to roll, but it may provide less power, since the ions have further to travel.
Briefs: Materials
Most space satellites are powered by photovoltaic cells that convert sunlight to electricity. Exposure to certain orbit radiation can damage the devices. Scientists have proposed a radiation-tolerant photovoltaic cell design that features an ultrathin layer of light-absorbing material.
