Drilling through many meters of ice to Europa’s ocean or to the pristine sub-surface layers of Mars will be hard. The Planetary Deep Drill prototype has shown that it may be a practical approach. Join Mat Kaplan and Planetary Society colleagues at the field test site deep in California’s desert. Emily Lakdawalla has good news from Venus and comet 67/P. Mat returns with Bruce Betts for What’s Up and a special, light-hearted feature celebrating relativity.
