Is something alive up there?

alive up there? Methane on Mars this week on planetary Radio. Radio. Hi everyone, welcome to Public Radio's Travel Show that takes you to the Final

Frontier.

I'm at Kaplan of the Planetary Society. Something is creating

natural gas on Mars. Is that something alive or is this a geological process?

No one would like to answer more than Michael Muma,

leader of the team that discovered

and localized methane plumes on the red planet.

He's our guest on today's show.

Bill Nye is back with thoughts about Hayabusa, the little Japanese asteroid probe.

Emily Lachto-Wala also returns to answer a question of yours about Venus and way down the line

Bruce Betts and I will give antimatter. It's due as we find out which of you is the

winner of another space trivia contest and explore the night sky.

Were you looking forward to the next space shuttle lift off?

Well, keep looking.

NASA has announced that Discovery's mission to the International Space Station must be delayed

again as they continue to work on a problem with some critical fuel valves.

No new launch date had been named as we finished this week's show.

Speaking of NASA, the agency has just signed a deal with the European Space Agency

for joint exploration of Jupiter and its moon Europa. The mission won't happen until about

20. It'll be followed by a similar shot at Saturn and Titan. Details are at

planetary.org.
