- Why does NASA use the International Space Station to fire lasers at trees?
"The sensor compares when it detects treetops to when it senses the ground. We can determine the height of the vegetation by converting that time to distance.
right now, the International Space Station is sending a rain of laser pulses toward Earth.
And it seeks to expose the deepest mysteries of the world's woods.
The GEDI project, jointly created by the University of Maryland and NASA's Goddard Space Flight Center, offers unique 3D mapping of forest areas in even the most remote locations.
According to Spanish scientist Adrian Pascual, a member of the GEDI scientific team and a professor at the University of Maryland, "It's a satellite the size of a refrigerator, weighs roughly 500 kilos, and which is docked or attached to one of the modules of the international space station."

Understanding the amount of carbon stored by trees and how deforestation affects the fight against climate change requires an understanding of the mission's data.However, GEDI's future remains questionable, and a campaign is currently under progress to guarantee the mission's continuation.
How the IEDG functions
The term "Global Ecosystem Dynamics Investigation" is an acronym.
The program's main component is a laser-firing equipment that has been connected to the International Space Station (ISS) since 2019.The ISS continuously circles the planet. Additionally, our GEDI satellite continuously generates laser pulses, "Pascual says.
It is possible to determine the structure of forests as well as the height of trees thanks to these energy pulses.
The tree canopy is the first thing this energetic pulse touches when it arrives on Earth, and it keeps moving until it reaches the ground

GEDI researchers look at variations in energy wave patterns to learn more about the forest's composition
"As a result, we can calculate the various vegetation levels, which helps us acquire a better understanding.LIDAR is a type,
planet's "lungs" is crucial for this reason.
