Some of the biggest discoveries we make in planetary science rely on the seemingly simple act of picking up and analyzing pieces of other worlds. When things go awry, scientists and engineers can sometimes squeeze amazing science out of a tough situation.
Three launches to the Moon and one each to Mercury and Mars; two arrivals at near-Earth asteroids; and an approach to an encounter with a distant Kuiper belt object are highlights we anticipate in 2018.
Looking back on 2017, we here at The Planetary Society are proud of what we have accomplished during this orbit of the Sun. Emily Lakdawalla, Jason Davis, Casey Dreier, and Mat Kaplan reflect on the year that was.
