These are tense times for scientists and engineers at NASA's Jet Propulsion Lab in Pasadena. Late Sunday night Pacific Time, they'll learn if nearly a decade of hard work will result in a priceless scientific laboratory landing safely on Mars or if the rover known as Curiosity will turn into a useless pile of junk. Everything depends on what happens during the seven minutes of terror, the time it takes the probe to go from the top of the Martian atmosphere to the planet's surface.
Viola da gamba players are a special breed — a tiny subset in the already small world of early classical music. They rarely meet their own kind, but once a year they come together for a week in July at an annual jam session they call a conclave. Wendy Gillespie, who just finished her term as president of the Viola da Gamba Society of America, says attending the event is the highlight of her year.
Earlier this year, the Australian government added the koala to the country's list of endangered species. By some counts, only about 100,000 remain in the wild in a country that once boasted a population in the millions. But many conservationists say the listing doesn't go far enough.
Paul O'Donnell is one of the many volunteers at Friends of the Koala in the northern New South Wales town of Lismore.
"We go out every day for about an hour or so collecting leaf; usually we get about one bin per koala," O'Donnell says.
That New Hampshire Sen. Kelly Ayotte is even being considered as Mitt Romney's running mate is somewhat remarkable. After all, New Hampshire has just four electoral votes, and Ayotte has been a U.S. senator — her first elected office — for less than two years.
But if any senator could be said to possess a refreshing charm, it might be Ayotte, 44, a mother of two young children, who still lives in her hometown of Nashua and is married to a former combat pilot.
This week, the world's largest democracy experienced the world's largest power outage. Nearly 700 million — that's more than half a billion — Indians were said to have been without power Tuesday. No air conditioning. No traffic lights. No metro system.
Most of the power is back now, but the outage had resonance for me from the long-ago years when I lived in New Delhi and experienced power failures almost as regularly as I did steaming cups of dark, sweet Indian tea.
The Uptown Vocal Jazz Quartet has been serenading audiences in its native Washington, D.C., across the country and even as far as France for more than two decades. But its members are finding ways to bring something new to their performances. Bandleader and co-founder Ginny Carr says she wrote the words and music to all 10 songs on the quartet's new album, Hustlin' for a Gig — a relative rarity in a jazz world defined by time-tested standards.
Mitt Romney is set to depart from London Saturday, after three days of photo ops and closed meetings. But his assessment of London's handling of the games drew a rebuke from Prime Minister David Cameron. Host Scott Simon chats with Financial Times columnist Gideon Rachman about the visit and the perceptions formed by Romney's hosts.
