Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

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

1. What is the platform class?Nano-satellite (1-10 kg mass), enabling cost-effective space deployment
2. What is the sensing modality?Hyperspectral imaging with hundreds of narrow spectral bands for detailed spectral analysis
3. What is a nano-satellite?A nano-satellite is a very small spacecraft that weighs between 1 and 10 kilograms. It is much cheaper and faster to build than larger satellites, so more people can send them to space.
4. How does NACHOS use hyperspectral sensors to study the air?NACHOS carries a hyperspectral imager that takes pictures in hundreds of very narrow color bands. This lets scientists see the unique light fingerprints of gases like nitrogen oxides and sulfur dioxide.

Nano-satellite: A small artificial satellite, typically weighing between 1 and 10 kilograms, facilitating lower launch costs and faster development cycles.
Hyperspectral Imaging: An advanced remote sensing technique that captures spectral information across numerous contiguous, narrow bands to identify and quantify materials based on their unique spectral signatures.
Atmospheric Chemistry: The scientific discipline focused on the study of chemical processes and reactions occurring within Earth's atmosphere, including the behavior of trace gases and aerosols.
Spectral Signature: The unique pattern of absorption and reflection of electromagnetic radiation by a substance, used to identify its composition.
