Despite their small sizes, a number of the satellites show unambiguous evidence for resurfacing. The goal was to develop a detailed model for heating of these small satellites, and then to explore the consequences of variations in the free parameters in the model. Specifically an attempt was made to determine for what range of conditions melting will occur in these satellites. Along with varying a number of model parameters, the important effects of inclusion of small amounts of ammonia and methane in the system were considered."> <base href="/"> <meta name="viewport"

name="citation_abstract" content="Voyager images of the satellites of Saturn and Uranus have shown that these bodies are characterized by remarkable diversity and surprisingly complex geologic histories. Despite their small sizes, a number of the satellites show unambiguous evidence for resurfacing. The goal was to develop a detailed model for heating of these small satellites, and then to explore the consequences of variations in the free parameters in the model. Specifically an attempt was made to determine for what range of conditions melting will occur in these satellites. Along with varying a number of model parameters, the important effects of inclusion of small amounts of ammonia and methane in the system were considered."><meta name="citation_author" content="Squyres, Steven W."><meta name="citation_author_institution" content="Cornell Univ.

of the satellites of Saturn and Uranus have shown that these bodies are characterized by remarkable diversity and surprisingly complex geologic histories. Despite their small sizes, a number of the satellites show unambiguous evidence for resurfacing. The goal was to develop a detailed model for heating of these small satellites, and then to explore the consequences of variations in the free parameters in the model. Specifically an attempt was made to determine for what range of conditions melting will occur in these satellites. Along with varying a number of model parameters, the important effects of inclusion of small amounts of ammonia and methane in the system were considered.</mat-card-subtitle><!----><!----><mat-card-content _ngcontent-sc170="" class="mat-card-content details-container"><div _ngcontent-sc170="" fxlayout="" fxlayoutgap="20px" class="detail-row ng-star-inserted flex-layout-33"><div _ngcontent-sc170="" fxflex="20" class="label flex-layout-34">Document ID</div><div _ngcontent-sc170="" fxflex="" class="data flex-layout-35"> 19870013922 </div></div><!----><div _ngcontent-sc170="" fxlayout="" fxlayoutgap="20px" class="detail-row ng-star-inserted flex-layout-36"><div _ngcontent-sc170="" fxflex="20" class="label flex-layout-37">Acquisition Source</div><div _ngcontent-sc170="" fxflex="" class="data flex-layout-38"> Legacy CDMS </div></div><!----><!----><div _ngcontent-sc170="" fxlayout="" fxlayoutgap="20px" class="detail-row flex-layout-25"><div _ngcontent-sc170="" fxflex="20" class="label flex-layout-26">Document Type</div><div _ngcontent-sc170="" fxflex="" class="data flex-layout-27"> Other </div></div><!----><div _ngcontent-sc170="" fxlayout="" fxlayoutgap="20px" class="detail-row ng-star-inserted flex-layout-39"><div _ngcontent-sc170="" fxflex="20" class="label flex-layout-40">Authors</div><div _ngcontent-sc170="" fxflex="" class="data flex-layout-41"><mat-chip-list _ngcontent-sc170="" class="mat-chip-list ng-star-inserted" id="mat-chip-list-1494748" tabindex="0" aria-required="false" aria-disabled="false" aria-invalid="false" aria-multiselectable="false" role="listbox" aria-orientation="horizontal"><div class="mat-chip-list-wrapper"><mat-chip _ngcontent-sc170="" fxlayout="" fxlayoutgap="20px" class="mat-chip mat-focus-indicator mat-primary mat-standard-chip _mat-animation-noopable flex-layout-42" tabindex="-1" role="option" aria-disabled="false"><div class="mat-chip-ripple flex-layout-43"></div> Squyres, Steven W. <!----></mat-chip><span _ngcontent-sc170="" class="flex-layout-44"><em _ngcontent-sc170="" fxflex="" class="ng-star-inserted flex-layout-45">(Cornell Univ.

Despite their small sizes, a number of the satellites show unambiguous evidence for resurfacing. The goal was to develop a detailed model for heating of these small satellites, and then to explore the consequences of variations in the free parameters in the model. Specifically an attempt was made to determine for what range of conditions melting will occur in these satellites.
