NASA’s TRACERS mission begins early science measurements in Earth’s southern polar cusp, tracking magnetic reconnection and particle inflow with two spacecrafts, Space Vehicle 1 and Space Vehicle 2.

Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their results match “local” measurements but clash with early-universe estimates, ...

Sulfur in soils near the moon's poles might help astronauts live off the land one day, making these measurements an example of science that enables exploration. When you purchase through links on our ...

(a) By keeping the temperature ratio between the hot and cold baths constant, varying the energy level spacing of the working substance allows the quantum engine to operate in different thermodynamic ...

Improvements to the SI are helping to evolve the science of accuracy and measurement. Democratization of the SI creates a traceability calibration chain accessible to anyone, anywhere. Digitization of ...

I was watching Ben Krasnow making iron nitride permanent magnets and was struck by the fact that about half of the video was about making a magnetometer – a device for measuring and characterizing the ...

In no field of science is the gulf between appreciation and importance as wide as it is for metrology. It’s not about the weather. Metrology is the science of measuring. It has a longer history than ...

Metrology is the science of precise measurement. It ensures accuracy and consistency across scientific, industrial, and engineering fields. Calibration is the process of aligning measurement ...

Edward Vicenzi is a guest researcher at the National Institute of Standards and Technology in the Material Measurement Laboratory. Christine France and Thomas Lam do not work for, consult, own shares ...
