    This guide provides an overview of 16 NASA missions studying the structure and evolution of the Universe. A description of the science and educational programs for each mission is provided, along with a list of other relevant resources and websites. The following missions are described in the guide: Advanced Composition Explorer (ACE), Astro-E2, Chandra, Cosmic Hot Interstellar Plasma Spectrometer (CHIPS), Constellation X-ray Mission (CON-X), Galaxy Evolution Explorer (GALEX) Gamma-Ray Large Area Space Telescope (GLAST) Gravity Probe-B (GP-B), High Energy Transient Explorer 2 (HETE-2), International Gamma-Ray Astrophysics Laboratory (INTEGRAL), Laser Interferometer Space Antenna (LISA), Microwave Anisotropy Probe (MAP), Rossi X-ray Timing Explorer (RXTE), Submillimeter Wave Astronomy Satellite (SWAS), Swift, and X-ray Multi-Mirror-Newton Mission (XMM-Newton).

    Air Masses

    Get PDF
    In this activity, students will examine the physical characteristics of several types of air masses (bodies of air that resemble the characteristics of the land surfaces beneath them). By analyzing maps of air temperature and of dewpoint temperature (prepared by the teacher), they will discover that air masses can be identified and defined by their temperature and moisture content. Student worksheets and links to the necessary maps are provided. Educational levels: Middle school, High school, Intermediate elementary

    Mechanical performance of glass-based geopolymer matrix composites reinforced with cellulose fibers

    Get PDF
    Glass-based geopolymers, incorporating fly ash and borosilicate glass, were processed in conditions of high alkalinity (NaOH 10-13 M). Different formulations (fly ash and borosilicate in mixtures of 70-30 wt% and 30-70 wt%, respectively) and physical conditions (soaking time and relative humidity) were adopted. Flexural strength and fracture toughness were assessed for samples processed in optimized conditions by three-point bending and chevron notch testing, respectively. SEM was used to evaluate the fracture micromechanisms. Results showed that the geopolymerization efficiency is strongly influenced by the SiO2/Al2O3 ratio and the curing conditions, especially the air humidity. The mechanical performances of the geopolymer samples were compared with those of cellulose fiber-geopolymer matrix composites with different fiber contents (1 wt%, 2 wt%, and 3 wt%). The composites exhibited higher strength and fracture resilience, with the maximum effect observed for the fiber content of 2 wt%. A chemical modification of the cellulose fiber surface was also observe
