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.”

The difficult journey to Olympic success

For Jessica Morgan, a young athlete New Zealand, a typical day starts early. Most mornings, she gets up 4:30 a.m., while her family is still bed, and trains before school. As an elite rower, she is one the best in her country, and she aims to compete in the next Olympic Games.

Jessica’s weekly schedule is grueling. She trains twice a day, six days a week, and competes in rowing events on the weekends. However, she’s also a normal schoolgirl, and like every other sixteen-year-old at high school, she regularly does her homework, too. Jessica’s motivation is impressive. She never hangs out with friends or takes a vacation. She isn’t only an amazing athlete – she usually gets good grades in school, too. Of course, it isn’t easy to become successful. Being the best at your sport requires hard work, determination, and the help of family and coaches. Young athletes’ relationships with their family and coaches can influence their success in the future. Jessica’s parents usually spend hours every week taking her to training and competitions, and they help her to eat a healthy diet. Her coach plans her training and enters her for competitions. But both parents and coach must offer emotional support, too – for example, when Jessica loses a competition or she gets an injury. Luckily for Jessica, she has a good relationship with both her coach and family. But in other cases, these relationships can place too much pressure on young athletes. For this reason, some of them lose their motivation to do well. For Jessica, the most important factor in her future success is her own desire to win. “I know talented young athletes who give up because they feel lonely without their friends,” she says. “But I prefer not to think negatively.” Jessica believes she is responsible for securing her future success. “It’s my decision to train every morning and go back to it again every afternoon. It’s my decision not to have a social life, and never to take a vacation.” Not everyone can cope with this kind of lifestyle. But each day Jessica moves one step closer to achieving her Olympic dream.
