Now lets get that Venus balloon project going!

That would be a good thing.Â* The Soviet Union's landers didn't last long
on the surface

given a temperature of 450 Celsius (842 F) it is not really surprising
that they didn't "laast long". It was incredible that they managed to
survive at all.

and the pictures returned revealed nothing but rocks.

Obviously at that temperatures and crushing pressures it would highly
surprising to see anything but rocks.

It's time that the atmosphere is explored since temperatures and
pressures are much more reasonable at altitude on Venus.

But let's temper our hopes for actual life.Â* What's been detected is a
chemical signature that could indicate life.Â* Or it could be from a so
far unknown chemical process that's unique to the atmosphere of Venus.

There is no known chemical process that could generate phosphine.

There is also no known chemical process that could generate life. So why
do you assume that life was generated from non life but phosphine was
not generated by non life. Generating phosphine from an unknown process
seems much easier to do than to generate life from an unknown process.
