Linear Energy Transfer Spectrometer Overview

Nic Stoffle, science and operations lead for the Linear Energy Transfer Spectrometer (LETS), provides an overview of the instrument. LETS launched aboard Astrobotic’s Peregrine Mission One flight on Jan. 8 as part of a Commercial Lunar Payload Services (CLPS) delivery to the Moon. The LETS radiation sensor will collect information about the lunar radiation environment and relies on flight-proven hardware that flew in space on the Orion spacecraft’s inaugural uncrewed flight in 2014. It is being developed at NASA’s Johnson Space Center in Houston.
