Houston, we have a podcast. Welcome to the official podcast of the NASA Johnson Space Center,

Episode 260, Mysteries of Dust. I'm Gary Jordan, and I'll be your host today.

On this podcast, we bring in the experts, scientists, engineers, and astronauts,

all to let you know what's going on in the world of human spaceflight.

Dust is really everywhere on Earth. In our own lives, we may think of

hazy skies that eventually just go away, but these tiny particles can have a big impact

on the planet's climate. One experiment that launched to the International Space Station on

SpaceX's 25th cargo resupply mission is taking a whole new look at Earthly Dust.

The Earth's surface mineral dust source investigation, or emit, is making history

by studying the composition of surface mineral dusts around the entire world.

Joining us from NASA's Jet Propulsion Laboratory to talk about emit, we have Dr. Robert Green

and Dr. David Thompson. Robert Green is the principal investigator of emit.

For more than 25 years, his research has used advanced imaging spectrometer instrumentation

to test hypotheses and pursue scientific investigations and applications research on Earth

and throughout the solar system. David Thompson is a senior research scientist at the Jet

Propulsion Laboratory and the California Institute of Technology. His research advances the algorithms

and practice of imaging spectroscopy for characterizing Earth and other planetary bodies.

He's an instrument scientist for NASA's EMIT and has a long history on the programming

end of spectroscopy. David's technologies have been fielded in four continents,

three oceans, three Earth orbiting spacecraft, and twice to the surface of Mars.

Robin David will clear the dust off the mysteries of emit and reveal how we'll soon be

able to better understand more about our home planet. Here we go, enjoy.
