A Powerful ISS Instrument Will Hunt For Minerals In Dusty Lands.

The vast African desert regularly burps up clouds of dust that fly into Europe, turning snow-capped mountains orange.

They travel clear across the Atlantic Ocean, fertilizing the Amazon rain forest with phosphorus.

satellites can track the plumes as they move around the atmosphere.

scientists don’t have enough data to show how dust could cool or warm the planet.

“Our data sets are based on 5,000 samples of soil says Natalie Mahowald.

Their instrument will use a powerful technique known as spectroscopy.

Any material’s molecules absorb and emit electromagnetic radiation

Astronomers can use a spectrometer to analyze the light coming off a distant planet.
