How Close To The Sun Can Humanity Get?
Summary
This episode details the Parker Solar Probe mission, which will fly closer to the sun than any previous spacecraft to study the solar corona and wind using four specialized instruments. The discussion covers the probe’s unique heat shield, its use of Venus flybys to reduce orbital speed, and the potential civilizational threats posed by coronal mass ejections. The segment concludes with a brief tangent addressing misconceptions about Maxwell’s demon and the thermodynamic costs of information processing.
