Science Friday
Looking for life in the clouds of Venus

And because we don't know how our DNA originated, we don't know which exact DNA-like molecule could be there.

Science Friday
Looking for life in the clouds of Venus

So the whole question of what to look for becomes really tricky.

Science Friday
Looking for life in the clouds of Venus

Well, we have a international consortium that I started and lead, and we call ourselves the Morning Star Missions to Venus.

Science Friday
Looking for life in the clouds of Venus

Missions, plural.

Science Friday

And we envision a series of small focus missions, each building on the one before it, to search for signs of life and eventually life itself.

Science Friday

So it won't be like initially we get there and yay, we found life.

Science Friday

It's kind of a very long journey because we aim to find evidence for organic molecules.

Science Friday

Then next we'd aim to find very specific, complex organic molecules we're looking for.

And if we get far enough along, the end goal in the future is a sample return so that we can bring some of the clouds back to Earth to look at them with our incredibly sophisticated techniques here on Earth.

Science Friday
Looking for life in the clouds of Venus

Well, right now we have a series of planned missions.

Science Friday
Looking for life in the clouds of Venus

And the first mission is called the Rocket Lab Mission to Venus.

Science Friday
Looking for life in the clouds of Venus

And we work in partnership with Rocket Lab.

Science Friday
Looking for life in the clouds of Venus

Right now, I have been responsible for the science team and the instrument, and our instrument is built.

Science Friday

In parallel to this, Rocket Lab has built our entry vehicle.

Science Friday
Looking for life in the clouds of Venus

It's like a little capsule that will be dropped off in the Venus atmosphere.

Science Friday

And this capsule, this is like a small, cheap mission.

Science Friday
Looking for life in the clouds of Venus

It's our first mission, largely privately funded, that will go to Venus.

Science Friday

And this capsule will be dropped off in the atmosphere and will slow down due to its own drag and last for about five minutes in the clouds.

Science Friday
Looking for life in the clouds of Venus

And this capsule has a very special heat shield on it

supplied to us by NASA Ames so that the capsule will not get destroyed as it races through the top part of the Venus atmosphere.
