2020.6.17 observe https://www.history.nasa.gov/hubble/ 2008 . a large orbital telescope would make a contribution to our knowledge of cosmology," by helping scientists study stars, measure distances to galaxies, and investigate the physics behind our universe. 2.4 meter mirror Among the many technological advances used in the telescope's construction was the computer-based laser grinding system used by Perkin-Elmer to craft the observatory's primary mirror. Hubble was finally launched aboard Discovery on April 24, 1990. The telescope's original equipment package included the Wide Field/Planetary Camera (WF/PC), Goddard High Resolution Spectograph (GHRS), Faint Object Camera (FOC), Faint Object Spectograph (FOS), and High Speed Photometer (HSP). a spherical aberration in the primary mirror, due to a miscalibrated measuring instrument that caused the edges of the mirror to be ground slightly too flat. Engineers rushed to come up with a fix to the problem in time for Hubble's first scheduled servicing mission in 1993. The system designed to correct the error was designated COSTAR, for Corrective Optics Space Telescope Axial Replacement. COSTAR was a set of optics that compensated for the aberration and would allow all of Hubble's instruments to function normally. -- components, technologies gyroscopes -- maintenance upgrades improved technology solar panels
2020.6.17 observe - The story of x-rays is compelling. Gaining access to the inner working of the human body involves so much interest and fascination. Just feeling the outside gave hints of what was inside. Physicians today still use touch along with modern observation techniques and technologies to assess conditions. But imagine the surprise and delight to "see" inside, as -- must have felt when he produced the x-ray photograph of his wife's hand. No wonder that this photograph generated enormous interest. It has tremendous appeal to everyone who has been curious about the hidden inner structures of the body. The field of imaging has expanded and opened avenues of exploration and discovery that were simply not possible without it. While we usually associate X-rays with medical imaging for diagnostic and research, x-rays are utilized for discovery in many other areas. -- space construction -- other imagining discovery stories stories

X-Rays were first discovered in 1895 by German scientist, Wilhelm Roentgen. Roentgen won the first Nobel Prize in physics in 1901 for his discovery. He was -- experimenting with electric currents *
Michael Faraday (1821) – conducted his first experiments on electrical discharge in a partially evacuated glass vessel. He discovered that the ‘voltaic arc’ was accompanied by the florescence of gas– he called ‘radiant matter’.
Julius Plucker (1850) – First to observe Green Glass Flouresence in partially evacuated discharge tubes.
Wilhelm Hittorf (1870) – discovered florescent discharge, he termed ‘cathode rays’.
2020.6.16 ultrasound - 1940-1950s Ultrasound is energy generated by sound waves of 20,000 or more vibrations per second. Ultrasound is used in an array of imaging tools. Used for medical diagnostics, ultrasound uses sound waves far above the frequency heard by the human ear. A transducer gives off the sound waves and reflected back from organs and tissues, making a picture of what’s inside the body to be drawn on a screen. Examining the health of an unborn baby, analyze bone structure or looking for tumors -- transducer
