Camp David, in the Maryland hills outside Washington, D.C., is usually a place for the president and his family to get away from work, a wooded refuge with a swimming pool, tennis courts and a putting green.

This weekend, though, President Obama is bringing work with him to the camp — along with the leaders from most of the countries with the world's largest economies.

The Group of Eight is meeting in the rustic setting, but the agenda will be all business.

Fresh Air Weekend highlights some of the best interviews and reviews from past weeks, and new program elements specially paced for weekends. Our weekend show emphasizes interviews with writers, filmmakers, actors, and musicians, and often includes excerpts from live in-studio concerts. This week:

Moments after ignition, a privately funded spacecraft aborted its liftoff, delaying its mission to the International Space Station.

SpaceX's unmanned rocket had a one-second window to take off from Cape Canaveral in Florida on Saturday morning, and the failed launch means the next opportunity won't be until early Tuesday morning.

The founder of SpaceX, Elon Musk, had been tweeting from the company's California headquarters leading up to the scheduled launch time of 4:55 a.m. ET.

Joint Base Lewis-McChord is at the center of yet another high-profile murder case. The Army announced Friday that Sgt. John Russell will face trial at Lewis-McChord in connection with a 2009 killing spree in Iraq.

And we briefly note the passing of one of the world's great opera singers: German baritone Dietrich Fischer-Dieskau died today. He was 86. From his first recital in Berlin in 1947 until his retirement in 1992, Fischer-Dieskau is in demand at opera houses and concert halls the world over. He was especially known for his interpretations of Schubert songs, like this one from the song cycle "Winterreise" or "Winter Journey."

Yes, hepatitis C is big among baby boomers. And the feds are moving toward a recommendation that all of them get tested at least once for the infection.

But new hepatitis C cases are cropping up in young people, too, and some of them live in out-of-the-way places that haven't been hotbeds for the illness.

Back in 1969, when Neil Armstrong and Buzz Aldrin landed on the moon, there were no guarantees. There were no guarantees that they'd make it there and there were no guarantees that they could make it back home.

President Richard Nixon and his speech writer William Safire knew that. So, imagining a situation in which the American astronauts were doomed in an alien land, Safire drew up a plan to mark their inevitable demise in a dignified way.

It was almost one year ago that the space shuttle Atlantis rose into the sky on a pillar of flame for the last time. The shuttle program ended forever with that mission. American astronauts were left to hitch rides on Russian space capsules, and American kids were left with no tangible direction forward for their dreams of a high-tech, space-happy future.

Tomorrow morning, the unmanned Falcon 9 rocket is scheduled to lift off from Cape Canaveral so that supplies can reach the space station.
