Cameron and Love discuss the progressive understanding of scientific concepts. They compare Newton's Laws to Einstein's Theory of Relativity, and express concerns for Earth's climate and population.

Replicating Earth's Life Support Systems (05:36)

Love describes air and water recycling technologies on a spacecraft, and explains that colonization of other planets is not yet feasible. Cameron and Love discuss the rise of oxygen in our atmosphere and maintaining its balance.

Becoming an Astronaut (03:38)

Love was a planetary scientist before becoming an astronaut. He grew up exploring Oregon's landscape, and was passionate about discovery. Cameron and Love discuss human curiosity and the reliability of science.

Inhabiting Mars (07:44)

Love describes the vast energy required for colonization; terraforming Mars is not currently possible. He recounts his time in space, and discusses the human connection to Earth's natural systems.

Submersible Research (06:36)

Love describes a mishap while piloting NEEMO16 for an underwater research project. The submarine was trapped in a current; his training and methodical thinking provided means for recovery.

Preparation As Courage (05:39)

Cameron and Love discuss avoiding panic in unnatural situations through training. Love describes his space walk.

Value of Space Administration (06:50)

NASA receives 0.4% of the Federal Discretionary Budget; it runs global positioning and earth science satellites, and American spacecraft. Love compares the benefits of space programs with attending college, and the benefits of robotics to human understanding.
