Russia's Venera 9, the first spacecraft to land on another planet, took a crude, tantilizing image of the surface of Venus (http://www.russianspaceweb.com/venera9_mitchell.html) before burning up less than an hour after landing. I thought it would be fun to recall this image in light of the crystal clear, great views of Mars coming from the Rovers Spirit and Opportunity.

Here is a Venera 10 image (http://www.russianspaceweb.com/venera10_mitchell.html)

Images linked from the Russian Spaceweb (http://www.russianspaceweb.com/venera75.html)

I don't know Donald Mitchell, but he has an interesting website about The Soviet Exploration of Venus (http://www.mentallandscape.com/V_Venus.htm).

Wonder how long we could get something to survive on Venus. One of the Veneras lived almost two hours, didn't it?

I wonder how long its gonna take humans before they start colonizing Venus, like the way Arthur C. Clarke had them do it in 3001: The Final Odyssey.

BTW, is the height of the Maxwell Montes mountain range more or less fixed or does it vary considerably with time?

There was this discussion LINK (http://www.badastronomy.com/phpBB/viewtopic.php?t=10451&highlight=venera) about six months ago about a computer buff who is working on cleaning up the images using current software.

I've wondered that myself. Perhaps if we sent it to the poles somewhere on the darkside then it could survive longer? Of course, then it wouldn't be able to see much of anything. :-/

Venus is almost uniformely 485C because the dense CO2 atmosphere traps everything in. It does not radiate out on the nightside.

The site with the Venus images is really really interesting; be sure to read the whole thing: http://www.mentallandscape.com/V_Venus.htm

It is amazing how many times the phrase "stranded in orbit" or "crashed into [insert name of ocean]" occurs in the history of intrplanetary probes.

This is my favorite Venusian landscape image.

I love the mysterious history of Venus having had a completely molten surface a few million years ago. It would have been so cool if it had occurred in a time it could have been observed. We might have thought Venus was always molten and had never cooled rather than having sequences of cooling and melting.
