Understanding NASA's Cryosphere Missions

What is the primary focus of the GRACE-FO mission?

• Measuring ice sheet height

• Tracking variations in Earth's gravitational field

• Monitoring underground water storage

• Studying ecosystem structures

How do the GRACE-FO satellites detect changes in Earth's gravity?

• By using a single laser beam

• By measuring the distance between two satellites

• By analyzing temperature variations

• By observing changes in satellite color

What technological advancement does ICESat-2 have over its predecessor?

• It measures gravitational fields

• It is powered by solar energy

• It operates with a larger satellite

• It uses 6 laser beams instead of one

Why is it important to measure ice sheet elevation changes?

• To understand the drivers of climate change

• To track the migration of polar bears

• To determine the color of ice

• To measure the temperature of ice

What additional insights do the GRACE-FO and ICESat-2 missions provide beyond cryospheric objectives?

• They help in predicting weather patterns

• They offer insights into underground water and ecosystem structures

• They track ocean currents

• They measure atmospheric pressure
