TEXT 1: How brightly the moon glows is a mystery, but maybe not for long.
“The lunar dark side may be the moon’s more mysterious face, but there’s something pretty basic scientists still don’t know about the bright side — namely, just how bright it is.
Current estimates of the moon’s brightness at any given time and vantage point are saddled with at least 5 percent uncertainty. That’s because those estimates are based on measurements from ground-based telescopes that gaze at the moon through the haze of Earth’s atmosphere.
Now, scientists have sent a telescope beyond the clouds on a high-altitude airplane in hopes of gauging the moon’s glow within about 1 percent or less uncertainty, the National Institute of Standards and Technology reports in a Nov. 19 news release.
Knowing the exact brightness of Earth’s celestial night-light could increase the reliability of data from Earth-observing satellites that use the moon’s steady glow to check that their sensors are working properly. Those satellites keep tabs on things like weather, crop health and dangerous algal blooms.”
