Welcome to Firewall's Flashpoints: this episode explores what it really takes for humans to live in space — from everyday challenges on the ISS like pre-prepared food and precision toilets to the engineering feats that let rockets escape Earth's gravity.

We examine reusable rockets such as SpaceX's Falcon 9, the legacy of Apollo 11, and the prospects for future homes on the Moon and Mars, including recycled air, water, and indoor gardens. Space is shifting from exploration to destination — the episode asks not if, but when, humanity will live off-world.
