Emily Lakdawalla coined the phrase, and it is exquisitely appropriate. We’ll visit the Jet Propulsion Lab on its Icy Worlds Day to learn more about spacecraft exploring Ceres, Enceladus and Europa from leaders of these missions. Emily Lakdawalla has assembled a family album for the two moons of Mars. Casey Dreier stands in for Bill Nye with a special review of the new NASA budget. And a healthy, hearty Bruce Betts is back with lots of What’s Up in the night sky.
