Imagine you're a crew member aboard a space craft. Beyond the safety of the hull lay a hostile wilderness, devoid of oxygen and home to a deadly mix of photons and cosmic rays.

In commentary for the latest episode of GZERO World, Ian Bremmer is taking a look at the challenges and opportunities of the COVID-19 pandemic.
