Questions & Answers

Q: What is Icesat-2 and what are its objectives?

Icesat-2 is a NASA satellite designed to measure changes in ice sheets, sea ice, and glaciers. Its objectives include improving measurement of elevation change, ice sheet dynamics, and sea ice thickness.

Q: How does Icesat-2 measure the thickness of sea ice?

Icesat-2 measures sea ice thickness by using a fast pulsing laser instrument that takes precise near-continuous measurements across its beams. It compares the height of ice sticking out of the ocean to the height of water between ice flows, known as leads.

Q: What new insights can Icesat-2 provide?

Icesat-2 will provide data that helps measure rapid changes in ice, improve understanding of sea level rise, and contribute to finding new things about ice that we didn't know to ask. It will shed light on climate patterns and the impacts of global warming.

Q: What are the potential applications of Icesat-2 data?

The data from Icesat-2 can help scientists better understand climate patterns, ice dynamics, and sea level rise. It can also aid in studying the impacts of melting ice on ecosystems and weather patterns.

Summary & Key Takeaways

• NASA's Icesat-2 satellite aims to gather data on the changing ice regions of our planet, particularly focusing on ice sheets and sea ice.

• The mission is a follow-up to Icesat-1 and aims to improve measurements of elevation change, thickness, and dynamics of ice.
