The Planet Venus (Luis Ricardo Falero,1882)

There is thrilling news for fans of our nearest planetary neighbor, the mysterious and beautiful hell-world, Venus. NASA has just announced two exploratory missions to Earth’s hot-mess of a twin. Long-time readers know that, in addition to dreaming of floating cities and artificial ecosystems on Venus in the future, Ferrebeekeeper is fascinated by the planet’s past.

In the early twentieth century, astronomers thought that beneath the clouds of Venus, there might be a lush jungle or tropical swamp teeming with strange sensuous lifeforms. Alas, the first probe to descend below the clouds melted on a surface hot enough to, uh, melt solidly constructed Soviet space probes. Enthusiasts of space colonization (and enthusiasts of exploring planets that a human visitor might possibly survive) quickly turned their attention elsewhere. But those sweaty palmed early twentieth century space buffs were not necessarily wrong. A billion years ago, Venus may well have had liquid oceans and temperate skies (if not necessarily lizard men and sultry Amazons), but then something went appallingly wrong and the world melted. The seas boiled away (assuming they ever existed). The sky turned into a mad scientist’s pressure cooker, and the surface turned inside out through a strange planet-wide volcanic process.

If this happened to your next-door neighbors’ place, you would probably be curious about what happened! Even if you didn’t care much about your neighbors, there would be prudent reasons of self-interest to figure out why their once comfy home was now 470 degrees Celsius with an atmospheric pressure akin to what is found a kilometer below the waves of Earth’s oceans! However what happens in a speck of light in the night sky is an abstract concern to a lot of people and Venus exploration has languished for decades…until now!

NASA has finally decided to see if Venus ever had liquid oceans or a surface akin to that of Earth. In coming years, the space agency will launch the DAVINCI and the VERITAS missions. Davinci will feature a spherical falling probe which will comprehensively assay Venus’ atmosphere as it drops through the clouds. Not only will Davinci sniff for traces of a lost ocean, it will seek other gases and volatile compounds which can tell us about the past of the planet (and whether we could build a flying cloud city there in the present). It will also photograph the perplexing “tesserae” features of Venus’ surface in high definition.

Veritas is even more concerned with the surface of Venus and will scan and observe the planet by means of next generation imaging technology. This should tell us about the surface (and deeper features) of the planet and finally answer whether the planet is still geologically active and document what it is actually made of. Answers to profound questions about our sister world are finally forthcoming! If you would like to know technical specifications about these missions, you should head over to NASA’s webpage.

We will be talking more about Venus as the missions get closer, but isn’t it thrilling to finally have some good news!
