In Memoriam

Remembering Our Pioneers: PSI In Memoriam

The In Memoriam page at the Planetary Science Institute is a heartfelt tribute to those we have lost – extraordinary individuals whose contributions have left an indelible mark on planetary science and inspired many others in their journey.

These luminaries went beyond being just researchers and educators – they were trailblazers who dared to venture into the unknown, broadening our understanding of the cosmos, and opening doors to new discoveries.

In remembering them, we acknowledge their enduring influence on PSI and the global scientific community. Their spirit continues to fuel our pursuit of knowledge and inspires future generations of scientists.

The In Memoriam page stands not only as a tribute but also as a commitment. It’s our pledge to continue their legacy of exploration, learning, and discovery, to honor the invaluable contributions they have made to the field of planetary science.
