Rocket thrusters, giant airbags, and a sky crane, these are just a few ways we have landed on other planets. This episode of STEM in 30 will explore the engineering behind these different techniques and what is in store for future missions, and features NASA scientist Ian Clark, Goddard Historian Bill Siders, and Astronauts Paolo Nespoli and Timothy Kopra.
