PREVIEW: #OUMUMUA: From a conversation with NASA David Grinspoon, Senior Scientist for Astrobiology, re the theory of Panspermia and the interstellar object Oumuamua and its ilk. More later on Oumuamua, what we know and don't know, and what plans to study the next such?

At Honda, we've been engineering cars for over 70, 75 years actually.

0:06.5

We know that excellence takes time.

0:09.2

So you can rely on the Honda engineering in the all-new ENY1, with a range of up to 250 miles on a single charge

and up to 5 years warranty, servicing and roadside assistance.

Our first electric SUV, the ENY1.

0:24.0

Oh, a whole in one.

Yes!

This is John Batcheter speaking with David Groon, a long-time colleague now, senior scientists

0:35.3

for astrobiology at NASA, about a moo-mooa, the interstellar asteroid comet dashed through the solar system on its path for eternity.

0:46.7

However, a moo-mooa came from another solar system.

0:51.1

The first ever found, although the theory is there are many of them and we're

0:55.6

watching for more. The question is the theory of pan-spermia, that is that life, whatever we regard it as life as we understand it, carbon and water

1:08.8

based. Life spread in the solar system is a theory. So did it spread between solar systems and how

1:17.8

would it be carried? An asteroid comment similar to a moo-amoo, a question mark. I asked David about this general

1:25.8

logic without evidence that there is life on other planets in our solar

1:31.7

system. We haven't found it yet. It's logical but not yet and

1:36.6

therefore can we extend that to other solar systems. David Grinsboon, senior Scientist for Astrobiology at NASA.

1:45.0

Well, it's tantalizing, isn't it, to think that not only might life naturally spread between the planets in one solar system as has been

proposed by by meteorites through our own solar system when the planets were young but

could you somehow have organisms that could survive that
