The White House took note of the launch of Chandrayan 1, saying it was "very interesting" as well as "encouraging" and "exciting".

Dana Perino [Images], the White House Press Secretary, was asked to comment on whether the President George W Bush [Images] is aware of the launch of Chandrayan 1 whose payload, includes that of the NASA [Images].

"I haven't spoken to the president about it. I saw that story. It was very interesting. We noted it. It's very encouraging for India, I'm sure very exciting," Perino said.
