The geologist Sanjeev Gupta tells Michael Berkeley about his search for evidence of ancient life in rocks on Mars with the help of NASA’s Mars Rovers, and he plays unique recordings of sounds from the surface of Mars.
Professor Sanjeev Gupta is a scientist who takes the long view, the very long view, into Deep Time. As the Royal Society Leverhulme Trust Senior Research Fellow at Imperial College London, he investigates how landscapes have evolved over vast spans of time. His work as a geologist has meant camping out alone for months at a time in some of the world’s most remote places.
And Sanjeev Gupta is part of a team of hundreds of scientists working on one of humanity’s most ambitious expeditions ever - NASA’s three billion dollar Perseverance Mars Rover which is helping us to understand what that planet was like an astonishing three-and-a-half billion years ago. The team is searching for evidence of ancient life in rocks on the Red Planet, rocks that will hopefully be returned to earth for analysis in 2031.
Music is vital to Sanjeev Gupta’s life. He brings Michael Berkeley music by Bach, Messiaen and Handel and by contemporary composers Peteris Vasks, John Luther Adams and Anna Meredith, music which conjures ‘visions of the beyond’ – starlight, canyons, oceans and heaven.
Sanjeev describes the surreal experience of helping to operate the Perseverance Rover as it landed on Mars in February 2021 from a flat above a hairdresser in Lewisham when restrictions prevented him from travelling to NASA Mission Control in California.
And he recalls the transcendent experience of listening to music alone on long field trips in the vast deserts of Utah.
