Page 207 - The purpose of Spacelab is to provide ready access to space for a broad spectrum of experiments in many fields and from many nations.
Page 98 - It will operate in the 1 mm to 30 micron wavelength region where the Earth's atmospheric opacity makes ground-based observations nearly impossible. The primary mirror will be 20 m in diameter, made up of 37 individual segments. The reflector will be actively controlled to provide an overall...
Page 24 - ISPM investigations were intended to study, as a function of solar latitude, the properties of the solar corona, the solar wind, the structure of the Sun-wind interface, the heliospheric magnetic field, solar and nonsolar cosmic rays, and the interstellar/interplanetary neutral gas and dust.
Page 130 - Origin of Plasmas in the Earth's Neighborhood — Final Report of the Science Working Group,
Page 89 - ... segment of the Civil Space Program, if not the required funding, seem well in hand through • the turn of the century and beyond. Of the eight concepts noted in Reference 5, only one, the Solar Coronal Diagnostic Mission (SCDM), cites any critical technology needs. A pioneering mission, the SCDM would, for the first time, Investigate the structure, dynamics and evolution of the corona. Besides knowledge gained about the sun itself, the SCDM would also aid greatly In developing the ability to...
Page 204 - Spacelab are operated by a team of up to four payload specialists who normally work in the laboratory, but spend their off-duty time in the orbiter cabin. The purpose of Spacelab is to provide a ready access to space for a broad spectrum of experimenters in many fields and from many nations. Low-cost techniques are envisaged for experiment development, integration and operation. The aim of this document is to provide a brief summary of Spacelab design characteristics and its use potential for experimenters...
Page 64 - A parabolic primary mirror, 1.25-m aperture f/36, will provide diffraction limited solar imaging in the spectral region 115 run to 1000 nm. The mirror will have a limiting angular resolution of 0.1 arc sec at 500 nm , equivalent to 72 km at the surface of the sun. An articulated primary mirror actuator assembly will provide active alignment, focus, sub-arc second pointing, rastering, and up to + 0.5 offsets. SOT as the baseline facility will accommodate various Science Instruments (Sis) at its focal...
Page 45 - Planetary Exploration Through Year 2000 - A Core Program, Solar System Exploration Committee of the NASA Advisory Council, 1983.
Page 154 - TDRS (a minimum of 85 percent of the orbital period). Based upon current mission model projections, no scheduling restrictions should be encountered for return link service. Forward link service is time-shared with a maximum bit rate of 10 kb/sec and supports one user at a time. The MA service will operate at S-band.
Page 54 - Telescope (ST) contains a 2.4-meter telescope designed for scientists to observe the universe with a clarity and to distances never before achieved. The Pointing Control System (PCS) controls the Space Telescope through maneuver and science modes of operation.
