Fittingly, the very first mission Smrekar worked on was NASA’s ambitious (and wildly successful) Venus orbiter Magellan. Launched in 1989, Magellan was equipp...

Venus currently has a surface temperature of 840 degrees F (450 degrees C) – the temperature of an oven’s self-cleaning cycle – and an atmosphere dominated by carbon dioxide (96%) with a density 90 times that of Earth’s. Venus is a very strange place, totally uninhabitable, except perhaps in the clouds some 40 miles (60 km) up where the recent discovery of phosphine may suggest floating microbial life. But the surface is totally inhospitable. However, Venus once likely had an Earth-like climate. According to recen...
