On Wednesday, the Indian space agency ISRO celebrated as its Chandrayaan-3 craft successfully made a soft landing at the lunar south pole. This is the first mission to explore the region around the moon’s southern pole, and a major success for ISRO. The mission plans to use a robotic rover to conduct a series of experiments over the course of about 2 weeks, largely centered around the availability of water and oxygen-containing materials.
Less than a week earlier, a Russian craft, Luna-25, crashed onto the moon. It would have been Russia’s first moon landing in 47 years. The cause of the crash is not yet known. Maggie Koerth, science journalist and editorial lead for CarbonPlan, joins guest host Flora Lichtman to talk about the two lunar missions and whether the flurry of activity signals a new space race.
They’ll also discuss other stories from the week in science, including a new analysis of the Y chromosome, work on the camouflage skin of the hogfish, and a setback in a mission to clear up space junk.
What’s The Human Cost Of Alaska’s Mineral Boom?
A dusting of snow clings to the highway as Barbara Schuhmann drives around a hairpin curve near her home in Fairbanks, Alaska. She slows for a patch of ice, explaining that the steep turn is just one of many concerns she has about a looming project that could radically transform Alaskan mining as the state begins looking beyond oil.
Roughly 250 miles to the southeast, plans are developing to dig an open-pit gold mine called Manh Choh, or “big lake” in Upper Tanana Athabascan. Kinross Alaska, the majority owner and operator, will haul the rock on the Alaska Highway and other roads to a processing mill just north of Fairbanks. The route follows the Tanana River across Alaska’s interior, where spruce-covered foothills knuckle below the stark peaks of the Alaska Range. Snowmelt feeds the creeks that form a mosaic of muskeg in nearby Tetlin National Wildlife Refuge, a migration corridor for hundreds of bird species.

Salmon Flourish After Mine Damage Restored In Alaska
On Friday, July 28, there were hundreds of juvenile salmon clustered in a pool, in clear water surrounded by a bank of fresh woody debris. Not 100 yards away, a spinning drum processed sediment to extract gold.
This land is managed by a mining company, but it’s also the site of a major stream restoration project. Thousands of salmon are returning to this stream in Hope, more than 100 years after aggressive gold mining affected the path of the river. The project to restore Resurrection Creek has brought together a coalition of stakeholders, including the present-day mining company that occupies the site.
The restoration of Resurrection Creek began in the early 2000s. The goal was to correct habitat damage caused by historic mining.
More than 100 years ago, heavy mining activity in the gold rush town affected the stream pattern, turning it from a meandering creek to a straight ditch. Jim Roberts is vice president of Hope Mining Company, and he said hydraulic mining in the early 1900s fundamentally changed the waterway.

All About Sea Otters
Last month, a rowdy sea otter was stealing surfboards off the coast of Santa Cruz California, biting chunks out of surfboards, and even catching a few waves.
It’s rare for a sea otter to get so close to humans in the wild. Authorities are trying to capture the otter, named 841, for her safety and that of the surfers. But, a month later, she remains at large.
Guest host Flora Lichtman talks with Jessica Fujii, sea otter program manager at the Monterey Bay Aquarium to get the 411 about Otter 841, and talk all things sea otter—including their sophisticated use of tools, carrying food in their armpits, and busting myths about hand holding.
