Laurence A. Soderblom Biography and Timeline

Callisto Imaging

Voyager 1 images show Callisto's heavily cratered and ancient surface.

Role range: 1944-2021

Io Sulfur-Rich Surface

Voyager colour imagery reveals extensive sulfur-rich deposits and varied volcanic terrain across Io.

Valhalla Basin Imaging

Voyager imagery reveals the vast multi-ring Valhalla impact structure on Callisto.

Enceladus Surface Diversity

Voyager images show Enceladus has contrasting cratered and smoother terrains, implying differing geological ages.

Mimas Herschel Crater Imaging

Voyager 1 returns detailed images of Mimas dominated by the enormous Herschel impact crater.

Miranda Coronae

Voyager images reveal large coronae and disrupted terrain across Miranda's unusual surface.

Triton Cantaloupe Terrain

Voyager 2 images reveal Triton's distinctive dimpled terrain and complex icy geology.

Triton Nitrogen Geysers

Voyager 2 imagery reveals active dark plumes rising above Triton's nitrogen-ice surface.

Triton Imaging

Voyager 2 reveals Triton's icy surface, plumes and unusual terrain.

Role range: 1989-1989

Triton Cantaloupe Terrain

Voyager images reveal distinctive pitted terrain on Triton resembling the surface texture of a cantaloupe.

Triton Geysers

Voyager images reveal active geyser-like plumes erupting from Triton's surface.

Triton Plume Height

Soderblom's team finds Triton plumes rising roughly eight kilometres before material is carried downwind.

Triton Young Surface

Voyager imagery indicates that much of Triton's surface is geologically young and has been extensively resurfaced.

Triton Geyser Study Published

Soderblom and colleagues publish a detailed characterization of the active geyser-like plumes discovered on Triton.
