NASA Just Launched A Mission To Calibrate Space-Based Instruments With Moonlight

Calibration is a necessary, if typically invisible, step in the successful operation of any scientific telescope. Without a known value to compare its readings against, data from telescopes could suffer from biases or transients that could completely misdirect scientists analyzing it. However, those same scientists also struggle to find good sources of data to calibrate against. Enter Arcstone - a technology demonstration mission that launched earlier this week that plans to use one particular source as a calibration dataset - moonlight.
