PV has traditionally been used for electric power in space. Solar panels on spacecraft are usually the sole source of power to run the sensors, active heating and cooling, and communications. Photovoltaics for Space: Key Issues, Missions and Alternative Technologies provides an overview of the challenges to efficiently produce solar power in near-Earth space and beyond: the materials and device architectures that have been developed to surmount these environmental and mission-specific barriers. The book is organized in four sections consisting of detailed introductory and background content as well as a collection of in-depth space environment, materials processing, technology, and mission overviews by international experts. This book will detail how to design and optimize a space power system's performance for power-to-weight ratio, effectiveness at end of operational life (EOL) compared to beginning of operational life (BOL), and specific mission objectives and goals. This book outlines the knowledge required for practitioners and advanced students interested in learning about the background, materials, devices, environmental challenges, missions, and future for photovoltaics for space exploration.

This charming story presents a new way for young children to understand how to creatively embrace who they are, no matter what others think. Carla's lunch box is filled with odd delights like the Olive, Pickle and Green Bean Sandwich, the Banana-Cottage-Cheese Delight, and the unforgettable Chopped Liver, Potato Chips, and Cucumber Combo. To Carla, they are delicious and creative lunches, but her teasing classmates are unconvinced and abandon her at the lunch table to eat her bizarre sandwiches alone. One day, however, tables turn when Buster--the worst tease of all--forgets his lunch on the day of the picnic and Carla thoughtfully offers him her extra sandwich. Her own spirited nature helps Carla teach her classmates that "unusual" can actually be good. Lively illustrations help showcase the book's messages of acceptance, tolerance, individuality, and creativity, and the funny plot and authentic dialogue are sure to make this tale a favorite among elementary school children. Carla's creative sandwich solutions provide young chefs-to-be with the inspiration to create sandwich masterpieces of their own.

When her teacher announces an upcoming in-school Vision Screening, Carla hopes she WILL need glasses and Buster hopes he WON'T. In eager anticipation, Carla - who loves to be unique - wears a different pair of handmade frames each day, crafted from tin foil, pipe cleaners, cardboard, and glitter. To both Carla's and Buster's dismay, the screening reveals that the only one who needs glasses is Buster. Carla hopes to cheer up her friend, accompanying him to the eye doctor to help him choose frames. They find a pair that suits him well, but Buster is still looking down. They have a meaningful chat in the car where Carla learns that, unlike her, Buster does NOT like to be different; he likes to fit in. But now he'll be the only one in class with glasses. When Carla cooks up a plan, it's clear to see that the power of friendship - and Carla's creativity - save the day. Carla's Glasses is a companion to the award-winning Carla's Sandwich.
