Russia was once the world leader in space exploration, but its space program has suffered a string of costly and embarrassing mishaps over the past year.

NASA says Russia is still a trustworthy partner, but critics say the once-proud program is corrupt and mismanaged — good at producing excuses, but not results.

The Memorial Space Museum in Moscow showcases the achievements of the Soviet Union's space program.

It's unlikely that the killing of 16 Afghan civilians on Sunday, allegedly by a U.S. Army staff sergeant, will drastically alter the course of the war.

U.S. and NATO strategy calls for a sizable contingent of international troops to stay in Afghanistan until 2014, with residual support after that. That timetable is unlikely to change.

But the task U.S. forces face in trying to stabilize the country could well be made more difficult by the shootings.

With a fierce yell and a resounding thwack, 13-year-old Japanese student Nanami Usui brings her bamboo sword down on her opponent.

By practicing Kendo, or Japanese swordsmanship, Usui is one of several students in the town of Minamisanriku who are rebuilding their confidence after last year's tsunami washed away their homes and shattered their hometown in the country's northeast.

Usui says she dreams of being a police officer, but she doesn't know yet where she wants to live and work.

Many details remain unknown about Sunday's shooting in southern Afghanistan, where a U.S. Army sergeant is suspected of walking through villages near Kandahar and killing 16 Afghan civilians.

But the shooting has raised the specter of reprisals against American troops and also led to questions about how much damage it could cause to the larger American war effort in Afghanistan.

Here's a look at what is, and isn't, known so far.

The Suspect

We're all familiar with the gruff Richard Nixon of the Watergate tapes. But the presidential library of the 37th president of the United States has an exhibit that shows a different side of him — the softer, gushy side of him that emerged as he was courting Pat Ryan, the woman who would become his wife.
