Telescopes - Focusing X-ray Telescope
... The Broad Band X-ray Telescope (BBXRT) was flown on the Space Shuttle Columbia (STS-35) as part of the ASTRO-1 payload ... BBXRT was the first focusing X-ray telescope operating over a broad energy range 0.3–12 keV with a moderate energy resolution (90 eV at 1 keV and 150 eV at 6 keV) ... The two Co-Aligned Telescopes with a segmented Si(Li) solid state spectrometer each (detector A and B) composite of five pixels ...
Solar Flare - Observations - Space Telescopes
... Two instruments of particular use for flare observations were the Soft X-ray Telescope (SXT), a glancing incidence low energy X-ray telescope for photon energies of order 1 keV, and the Hard X-ra ... satellites in geostationary orbits around the Earth that have measured the soft X-ray flux from the Sun since the mid-1970s, following the use of similar instruments on the Solrad ... GOES X-ray observations are commonly used to classify flares, with A, B, C, M, and X representing different powers of ten — an X-class flare has a peak 1-8 Å flux above 0.0001 W/m2 ...

The telescope had not been designed for repair or replacement so the EVA was a difficult one ... they sliced through the 20-layer thick thermal blanket to expose the telescope's faulty X-ray detector unit, the two men had to stop and rest several times, as they had nowhere to anchor ...

Famous quotes containing the words telescope and/or ray:

    The sight of a planet through a telescope is worth all the course on astronomy; the shock of the electric spark in the elbow, outvalues all the theories; the taste of the nitrous oxide, the firing of an artificial volcano, are better than volumes of chemistry.
    Ralph Waldo Emerson (1803–1882)

    It has never been my object to record my dreams, just the determination to realize them.
    —Man Ray (1890–1976)
