Project Hail Mary hits the big screen
20:28

Sarah Al-AhmedHOST
How well do you think the film kind of captured that complex question when it came to astrophage?
A
20:34Alexandra WitzeGUEST
I think both the book and the movie did a great job at that in astrophage because when I was reading that, when I was seeing it in the movie, it made me think very much of all the times I've reported on, oh, look, there's a hint of phosphine in the atmosphere of Venus, and is that a biosignature gas or not? Or oh my gosh, is there dimethyl sulfide in K2-18b, you know, an exoplanet that might also be a biosignature.
A
20:58Alexandra WitzeGUEST
Now, astrophage is not, you know, a molecule in a gaseous atmosphere, but it's the kind of thing...
A
21:05Alexandra WitzeGUEST
I mean, a- you know, I covered Allen Hill's A4001 when people were arguing about is this squiggle in a rock, you know, a fossil of a life form.
A
21:13Alexandra WitzeGUEST
And you sort of look at the astrophage and, you know, until you see it, you know, reproduce and spread or whatever, then it's obviously living, but what is it, right? What does it say? What does it say about what life is and how, like, weird and unique it might be and how similar to just, like, you know, microbes on Earth it might be as well too.
A
21:35Alexandra WitzeGUEST
So one of the things I really love about Project Hail Mary, and I have a lot of critiques as well too, but things I love is these two different alien species, right? You've got astrophage, which is like slimy algae stuff, non-sentient, but doing its own thing to evolve and survive in the universe.
A
21:53Alexandra WitzeGUEST
And then you've got the sentient creature, Rocky, which I guess we're not doing too many spoilers, but, uh, there is an alien creature named Rocky, and he is sentient.
9 MINS LATER

Sarah Al-AhmedHOST
It, it turned out, you know, clearly it's not astrophage, and it wasn't an imminent supernova, so what ended up being the case with Betelgeuse?
Behind the scenes with Artemis II’s scientists during the historic Moon fly-by

Mm.

Alexandra WitzeGUEST
-color difference, shadows, dynamic changes as kind of the light moves across the lunar surface.

Alexandra WitzeGUEST
That's stuff that a orbiter really just can't get, just a, a spacecraft with a camera taking pictures robotically.

Alexandra WitzeGUEST
There was a lot of talk about, "Wow, the moon is a lot browner than I thought." It's not just black and white.
B

Which do you think has stood out to you the most from those that you've seen?
Artemis II is go: humans head to the Moon after half-century absence

8:36BenjaminHOST
So how is this different?

Alex WitzeGUEST
Well, it depends on who you ask, but I- I talked to a lunar scientist yesterday who made the argument that this is different because there is a longer-term plan.

Alex WitzeGUEST
So the point of Apollo was to land a human on the Moon from the US before the Soviets did, and there wasn't really clear what was gonna happen after that.

Alex WitzeGUEST
Eventually, NASA pivoted to s- reusable space planes in the form of the space shuttle and the space station and Earth orbit as a destination to get to.

Alex WitzeGUEST
The argument this scientist made to me yesterday is that NASA has a plan for a longer-term return to the lunar surface to build a Moon base.
B
12:38BenjaminHOST
Are we hoping for something similar from the Artemis II mission, this kind of wonderful encapsulation of what's going on?
Slow Release Of Federal Science Funds Holds Up Research
A
3:34Alexandra WitzeGUEST
And once Congress has approved funds, what normally happens is the OMB would start giving out 30-day blobs, apportionments they call it.
