Planetary Radio: Don't Step in That Puddle!

The Planetary Science Institute's Amanda Hendrix is the guest for our July 1 episode. She finds water in the least likely places, including Luna.

Comparing Clementine and Chandrayaan-1 spectra from the Moon

In a paper recently published in the Journal of Geophysical Research, Georgiana Kramer and several coauthors performed a careful comparison of two data sets that seem like they're measuring the same things, so you'd think that the measurements they took would match between the two instruments. But they don't quite match.

Explore the Moon in 3D through the Chandrayaan-1 TMC image data set

Data from two of the cameras aboard Chandrayaan-1 are now available through the ISRO Science Data Archive (ISDA), a new(?) site that is being established to host the data from ISRO's deep-space missions.

Likely candidate for an un-collapsed lava tube

In February, the Chandrayaan-1 science team had a meeting in Ahmedabad, India, to share their results with each other.

Water on the Moon: Direct evidence from Chandrayaan-1's Moon Impact Probe

I've reported before about the detection of water on the surface of the Moon by the Chandrayaan-1 orbiter and the Deep Impact and Cassini spacecraft, but what I'm about to tell you about is actually more exciting: the direct detection of water in the lunar atmosphere by the Chandrayaan-1 Moon Impact Probe.

LPSC: Lunar Reconnaissance Orbiter results

A week later and I am finally getting to the mountains of notes I took on Moon-related talks I saw at the Lunar and Planetary Science Conference (LPSC) held in Houston last week.

The "Water on the Moon" Hoopla, Part 1: There's water on the Moon!

For a couple of weeks now, I've been hearing rumors about an upcoming announcement concerning Chandrayaan-1 Moon Mineralogy Mapper (

The "Water on the Moon" Hoopla, Part 2: The murkier part of the story

How much water is there on the Moon, and is it in a form that human explorers could use? This part of the story has many more questions and many fewer definite conclusions.

Space is vast. There's a lot of exploring to do.
