Journal Article Icarus · January 1, 2002 Differential scanning calorimetry indicates that adsorbed water and goethite, a product of hydrated ilmenite, are thermally stable over geologic time in the lunar polar regions. Adsorbed water can undergo burial as a result of several mechanisms, thereby a ... Full text Cite

A high-resolution solar telescope using dark-lens diffractive optics

Journal Article Solar Physics · December 1, 2001 A telescope based upon dark-lens diffractive optics would be a uniquely new instrument for solar astronomy. The image formation process in such a telescope gives an intrinsically higher resolving power and a greatly reduced image intensity compared to that ... Full text Cite

Forty years of development of active systems for radiation protection of spacecraft

Journal Article Journal of the Astronautical Sciences · July 1, 1999 A comprehensive survey of the literature relating to active spacecraft shielding is presented, including electrostatic and plasma as well as magnetic methods. A literature discussion is provided in order to give an overview of this field. The advent of hig ... Cite

X-ray and neutron diffraction of yttrium-barium-copper-oxide: Modeling diffraction intensity variations produced by surface leaching

Journal Article Journal of Materials Research · 1999 High normal current fluences have long been reported to produce major changes in the x-ray diffraction pattern of YBa2Cu3O7-x (YBCO). These x-ray diffraction effects have now been shown to result from the removal of barium from the YBCO near-surface lattic ... Cite

Application for deployed high temperature superconducting coils in spacecraft Engineering: a review and analysis

Journal Article JBIS Journal of the British Interplanetary Society · December 1, 1997 Superconductors have been proposed for many space applications. The development of high temperature superconducting materials makes feasible the use of field-generating coils deployed beyond the hull of interplanetary spacecraft and capable of producing ve ...

Extrasolar planetary detection via stellar occultation: a novel ″smaller, cheaper, faster″ concept employing the Hubble Space Telescope

Journal Article Proceedings of SPIE the International Society for Optical Engineering · December 1, 1996 The Hubble Space Telescope presents unique possibilities for the detection of extrasolar planets. The enormous difference in light intensity between such a planet and its associated star makes detection of any planetary signal intrinsically very difficult. ... Cite
