President Barack Obama and a group of brainiac young students played stump-the-astronaut with the current occupants of the orbiting space station.
This was an event beamed live between the White House Roosevelt Room (the bookcase has been converted into a whizbang video screen) and the space station.
Obama, phone cradled on his shoulder, talked to the group of astronauts sitting erect and being careful not to float away in their gravity-free environment.
The 12 middle school students from Michigan, Florida, North Carolina and Nebraska had lots of questions once Obama turned the microphone over to them, such as the age-old query: what can you really see on Earth from space?
“Yes, we can see a lot of great landmarks. We can see the Golden Gate Bridge (in San Francisco), the great skyscrapers in New York and the Grand Canyon is just breathtaking,” said one astronaut.
