Astronomycast Episode 640 Science Surveys newest projects and results. Welcome to Astronomycast

for Weekly Facts Based Journey Through the Cosmos. We help you understand not only what we know,

but how we know what we know. I'm Fraser Kane, publisher of University. I've been a space

in Astronomy Journalist for over 20 years. With me is Dr. Pamela Gay, a senior scientist for

the Planetary Science Institute and the Director of CosmicQuest. Hey Pamela, how you doing?

for 23 years. Yeah. Pretty funny. All right. So there are general purpose telescopes and missions

that astronomers can use to study specific objects and there are the survey missions that look

at the entire sky which astronomers can use to answer questions about the universe.

We've talked about surveys in the past but the lands keep is changing quickly so it's time for an

update. When we thought about a survey and I haven't like looked but it was several hundred

episodes ago when we talked about surveys. Yeah. And you know I've always been a gigantic fan

of survey missions in general because it like allows you to go after the fact, go back through the
