Big Picture Science

Getting a Spacelift — I need my space… but oh, how to get there? Whether it’s a mission to Mars or an ascent to an asteroid, we explore the hows of human spaceflight. Also, the whys, as in, why send humans to the final frontier if robots are cheaper? Neil deGrasse Tyson weighs in. Plus, the astronaut who lived on the ocean floor training for a visit to an asteroid. Also, the 100YSS – the 100 Year Starship project – and interstellar travel. And, as private rockets nip at NASA’s heels, meet one of the first tourists to purchase a (pricey) ticket-to-ride into space.
