Mars is no longer a watery world, so how did all of those gollies form?

We're digging into the mystery this week on Planetary Radio.

I'm Sarah Allah mid of the Planetary Society with more of the human adventure across our

solar system and beyond.

The oceans of Mars dried up or froze a long time ago, but some of the more recent features

on the planet's surface, like Martian gullies, suggest that they could have been formed

by flowing liquid water.

How is that even possible?

Our guests this week Jay Dixon and his colleagues think that they might have an answer, and it

has everything to do with the tilt of the red planet over time.

Then the ever awesome Bruce Bats will join me to talk about what's up in the night sky

this week.

We have to start off by congratulating the Indian Space Research Organization, or ISRO.

Your newest moon mission, Chandran III, successfully launched on July 14th.

Chandran III consists of a land or an aerover that will attempt to land near the moon's

South polar region on August 23rd.

You may remember that the Chandran II V-Crom land or crashed in 2019, but ISRO learned

a lot of lessons from that mission.

They say that they've performed numerous tests to ensure that Chandran III goes according

to plan.

And in other space news, data from the European Space Agency's Chi-Ops mission have revealed

the shiniest exoplanet ever found.
