Exploring the Universe: Ice Orbs

“Exploring the Solar System: Ice Orbs” is a hands-on activity in which visitors investigate a frozen orb, trying to learn about objects hidden inside. Participants learn that planetary scientists at NASA are investigating “icy worlds” in the outer solar system, looking for evidence of liquid water and possible signs of life beneath the icy surface.
