Hey, Curious Universe listeners.

I'm Jacob Penner, new producer here at the show.

I have a question for you.

If you could ask a NASA scientist or astronaut, anything, what would it be?

Well, here's your chance.

This season, we want to know what you're curious about.

Send us your question at NASA-curious Universe at mail.nassah.gov.

And we'll try to track down the answer.

Thanks.

And enjoy the show.

And great. L.E. Gofer launch.

And great news. All systems are go for launch of Falcon 9 and Issa's Euclid Space Telescope.

launched, I could see the intensely bright light, and I started counting seconds in my head.

Jason Rhodes is a scientist at NASA's jet propulsion laboratory.

He's an astrophysicist who studies what the universe is made of and how it's structured.

So Jason watched the rocket ignite silently.

Then he counted for about 20 seconds.
