The Discussion: This month Jeni has a PhD offer that's getting us all excited, Paul's been clocking up the miles to teach science and astronomy to schools and Ralph's just excited because he's got a new telescope.

Mat & Phil from Project Helium Tears join us again on the day they launched their 2nd Star Wars themed balloon to the edge of space.

The News: We start the news with last month's total solar eclipse seen from parts of Asia before explaining the research that suggests an ancient cataclysm caused Mars crust & mantle to shift. Then we discuss the launch of ESA's Exomars part 1. And we finish with a round-up of the news from NASA's Insight mission, the 1st analysis of the atmosphere of a super earth exoplanet atmosphere and the latest SpaceX attempt to bring down the cost of commercial spaceflight.

The Interview: For the interview this month we welcome Apollo 12 lunar module pilot and Skylab 2 commander Alan Bean. We discuss:

• Finding organic matter in lunar orbit
• Competing with smarter astronauts – and not being Clint Eastwood!

And the full hour long interview with Alan Bean will be released in May 2016.
