A reprieve of our visit with 97-year-old John Dobson this week on planetary radio. I'm at Kaplan of the Planetary Society.

It has been a good long while since we repeated an interview, but the holidays and a

short vacation have brought that rare event around again.

You'll hear brand new visits with Emily Lochuwala, Bill Nye, and Bruce Betts.

But we've also brought back one of our most popular guests from all of 2012.

If you missed John Dobson last September, you're in for a very special treat.

Of course, you lovers of the night sky know who John is.

He invented the elegantly simple Dobson telescope that put the universe within almost everyone's reach.

But there's much more to his delightful story.

First though we'll hear from the equally delightful Planetary Society senior editor Emily Loch Lachto-Wala.

Emily, it's my first chance to wish you a happy new year.

Thanks, you too, Matt.

We did do that little review last time we spoke of things coming up that you're looking forward to in 2013 but it

turns out that now you have much more information about this mission to Mars the

first ever from India that's right and the information was presented at a large science

conference actually the hundredth annual at these Indian science conferences in

Calcutta this week. They've selected five instruments for their payload.

It's kind of a broad payload, really.

There's a color camera, there's a thermal imaging

spectrometer, much like Themis on Mars Odyssey.

There's a methane sensor,

there's a kind of energetic particle sort of thing.
