Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is LASARsat known for?Revolutionized 3D forest structure mapping and biomass estimation from space
2. What is the mission operator?Canadian Space Agency (CSA)
3. What is the primary sensor technology?Spaceborne LIDAR (Light Detection and Ranging)
4. How does LASARsat help us learn about forests?By mapping how tall trees are, how many leaves they have, and how much wood is in the forest, LASARsat tells scientists how healthy the forest is and how much carbon it stores.
5. Why does LASARsat use lasers instead of normal cameras?Lasers can work even when the sky is cloudy or dark, so LASARsat can keep collecting data all the time, unlike regular cameras that need sunlight.

Remote Sensing: The acquisition of information about an object or phenomenon without making physical contact.
Forest Biomass: The total mass of living organic matter in a forest, a key indicator for carbon cycle studies.
Time-of-Flight: The duration it takes for a signal, like a laser pulse, to travel to a target and return.
