When Earth and Venus are at their closest points, they are only 23.7 million miles apart. Nonetheless, our sister planet remains a mystery. Several spacecrafts have been sent to the surface, but the planet’s extreme temperatures and high pressure inevitably disable and crush the crafts soon after landing. A properly outfitted rover that could withstand the atmosphere of Venus would illuminate our understanding as never before. Until then, Venus will continue to illuminate our own skies.
