This is WEEKEND EDITION from NPR News. I'm Scott Simon and we'll have to wait until June to learn what the U.S. Supreme Court has decided on the two gay marriage cases before it. But this week, the justices heard oral arguments and they gave perhaps some hints of their thinking. One case concerns the constitutionality of California's ban on gay marriage, the other case is a challenge to what's called DOMA, the Defense of Marriage Act.
We're joined now by NPR legal affairs correspondent, Nina Totenberg. Thanks for being with us.

You're listening to SCIENCE FRIDAY. I'm Ira Flatow. And for the rest of the hour we're going to talk about collisions, space collisions, space impacts, with Erik Asphaug, who's Ronald Greeley chair of planetary geology, School of Earth and Space Exploration at Arizona State University. Welcome to SCIENCE FRIDAY.
ERIK ASPHAUG: Thanks very much, Ira.
FLATOW: You must be very busy since this last collision in Russia of this asteroid.
When does a story about science become science fiction? Cosmologist Lawrence Krauss and theoretical physicist Brian Greene discuss how to spin a yarn about string theory or the Big Bang, without hyping the science. And novelist Ian McEwan, whose books touch on neurosurgery and quantum field theory, talks about what science offers to fiction.
The Sonoran Desert, which spans some 100,000 square miles in southwestern North America, is one of the most diverse desert ecosystems in the world. Host Ira Flatow and guests discuss some lesser known desert creatures, and explore the secret life of that American southwest icon, the saguaro cactus.
The year is 1915. A beautiful young woman bicycling through sun-dappled woods passes under an effigy of a German soldier and seems entirely unfazed. World War I is raging elsewhere in Europe, but here on the French Riviera life is serene.
The cyclist, Andree, is on her way to pose for an elderly Impressionist painter, Pierre-Auguste Renoir (Michel Bouquet), whom she somewhat startles by claiming to be an artist herself.

The Rev. Julio Gonzalez leads Easter Mass at El Santuario de Chimayo in 2007. Thousands of visitors make a pilgrimage to visit the small chapel annually every Easter weekend. Many people believe that the dirt inside the chapel has healing powers.
Driving in northern New Mexico requires special caution on Good Friday. Tens of thousands of people — some walking all night — are converging on the village of Chimayo to pray inside a 200-year-old chapel before a carved wooden image of Jesus.
As it does every year, the highway department has put out portable toilets, orange barriers, and signs warning motorists of "Santuario walkers."
