Wet Venus?

Researchers at Washington University in St. Louis, studying hydrous mineral decomposition rates at extreme temperatures, have concluded that hot and dry Venus may have been a wet planet in the past, like Earth and ancient Mars. The new evidence suggesting a wetter Venusian history comes from a series of experiments documenting the chemical stability of tremolite, a mineral that forms in the presence of water.

Misleading article (4.40 / 5) (#5)

The article offers no proof that there was water on Venus. The statement that it makes is essentially "I've proved that something created in water, tremolite, can survive on Venus. Now we gotta check for the existence of such stuff on Venus."

In other words, they've offered a means to find definate proof of water on Venus. But nothing has been discovered yet. We gotta hit the surface and try to find some tremolite there. Anybody wanna volunteer for an expedition? :-)

Researchers are jumping on the "there's life on my favourite planet" bandwagon and the media are helping them do it because they get to publish an interesting headline. As one of the guys behind the Mars Viking (approximately) said "nobody's going to spend billions on something that's merely a geology project".

Okay, you first. When you come back and say the A/C works like a charm I'll follow. Agreed?

I'll stay on the Earth. In addition to 800+ degrees F suface temperatures, Venus has an extremely dense atmosphere. Standing on the surface, you would feel 91 times the pressure you would feel here on the Earth. This is like being 1 kilometer below the surface of the ocean. In other words, you'd be crushed like a plastic coffee cup. Mars seems much more inviting.

This reminds me of all those old SF stories, where they portrayed Venus as a wet tropical paradise rather than the hot hellhole it really is. It kinda funny to think that the SF writers may have been right, but we were just a bit too late to see it.

Ray Bradbury? (5.00 / 1) (#15)

Wasn't Ray Bradbury the author of several Venus stories? I seem to remember in particular one about children anxiously awaiting "Sun Day", the one day of the year when the rain stopped, and they could see the sun for the first time.
