"A pair of balloon probes that floated in the atmosphere of Venus nearly 30 years ago may have run into a drizzle. This being Earth's hellish sister planet – where surface pressure is akin to being 900 m underwater and average temperatures are hot enough to melt lead – the shower wasn't made of friendly water but rather corrosive sulfuric acid. The finding comes from a re-analysis of data taken by the Vega 1 and 2 missions and may represent the first onsite detection of rain ever made outside of Earth. In 1984, the Soviet Union joined with several European countries to launch the Vega probes, a complex mission that dropped a pair of landers and balloons on Venus and then sent two spacecraft to make close encounters with Halley's comet in 1986. No other mission has ever deployed balloons on another planet. The two 3.5-m-diameter balloons floated for nearly two days in the Venusian atmosphere around 55 km above the surface. Unlike the hostile terrain below, the cloud layers at this height are a veritable wonderland. Temperature and pressure are comparable to Earth's average and there is ample sunlight streaming in from above. If not for the sulfuric acid clouds and hurricane-force winds, the atmosphere of Venus would be a comfortable living space. Most previous analyses of the mission noted that the balloons slowly leaked helium and descended as they traveled, and that has been considered the end of the story…"

"If not for the sulfuric acid clouds and hurricane-force winds, the atmosphere of Venus would be a comfortable living space." Well, yes. If not for those. It's always the little things that mess up a potential neighborhood. Bad street layout, too close to the highway, sulfuric acid clouds…

I was always taught to not sweat the "little things", but I think Parzival is right on this one. By the way, how does the article author reconcile: ….Venus would be a comfortable living space. with: …..where surface pressure is akin to being 900 m underwater and average temperatures are hot enough to melt lead…… I guess we all have different definitions of what "comfortable" is. |
