Water supplies in California are tight with the state's severe drought and that's putting a spotlight on hydraulic fracturing or fracking. The controversial oil and gas extraction technique uses freshwater, which can mean millions of gallons for each fracking site.
Lauren Sommer of member station KQED reports from California's Central Valley, where tensions between oil and agriculture are on the rise.
Keith Cowing discusses his campaign to save an old 1970s NASA spacecraft from becoming space junk. ISEE-3/ICE is a satellite that was once used to monitor space weather, but it's been unused for decades. NASA doesn't want to spend the money to bring it back to life, but Cowing and his colleagues are determined to do it. If they can raise $125,000 on a crowdfunding site called RocketHub, Cowing says they'll contact ISEE-3/ICE, wake it up and put it back to good use.
For the past month, in part of eastern Kansas, the prairie has been burning, as it does almost every spring. On some days, you could look toward the horizon in any direction and see pillars of smoke. The plumes of pollution have traveled so far that they've violated limits for particulates or ozone in cities as far away as Lincoln, Neb.
But here's the twist: Environmentalists have come to celebrate those fires.
This month, NASA revealed new details of the plan to send humans to Mars by 2030. It's an elaborate and expensive mission, involving a giant deep-space rocket, and roping an asteroid into the moon's orbit to use as a stepping stone to Mars.
But there are still some serious questions about a manned expedition to Mars. Namely, is it safe? That's where astronauts Scott and Mark Kelly come in. The Kelly brothers are identical twins, and the only siblings ever to both fly in space.

In the Atlantic forest of Brazil, a female marmoset monkey — a small, arboreal primate — fell from a tree to the ground, striking her head. This female, known to observing scientists as F1B and as dominant to other females in her group, was severely injured and died two-and-a-half hours later.
Is physics in crisis? An article in the May issue of Scientific American by physicists Joseph Lykken, from Fermi National Accelerator Laboratory, and Maria Spiropulu, from the California Institute of Technology, lay bare an issue that is keeping a growing number of physicists up at night.
New York City is 20 times more likely to flood during a storm than it was in the mid-1800s, partly owing to sea-level rise linked to global climate change, according to a new study.
The maximum water height at New York Harbor during storms such as Hurricane Sandy has risen nearly 2.5 feet since 1844, says the study, which was published in a recent issue of Geophysical Research Letters.
