What is the primary function of the GEDI instrument on the International Space Station?

• To measure atmospheric CO2 levels

• To identify minerals and rock types

• To study plant temperature

• To provide 3D views of forest height and structure

How does the ECOSTRESS instrument contribute to our understanding of plant life?

• By capturing images of natural disasters

What unique advantage do astronauts have when taking photographs from the International Space Station?

• They can only use black and white cameras

• They can only photograph during the day

• They can capture panoramic and oblique views

• They can take straight down images only

Why are panoramic views from astronauts' cameras particularly useful?

• They are only useful for studying plant species

• They offer immediate 3D pictures of natural disasters like wildfires

• They help in identifying minerals and rock types

• They provide a 2D view of the Earth's surface
