A tweet from the heavens

Tracy: What's your dream as a little boy?

Jack: Being an astronaut and then live in the space.

Tracy: Don't you think that would be boring? And you'd miss your family and friends who live on the earth.

Jack: Maybe that was true. But astronauts in the International Space Station can now communicate with people on the earth through internet and they can also browse the Web.

Tracy: Are there any computers in the International Space Station?

Jack: Well, there's an on-board laptop.

Tracy: Oh, that must be fantastic to browse the Web in the space.

Jack: Yeah. And they sent a tweet directly from the heavens on Friday.

Tracy: Is NASA worried the astronauts might spend too much time online?

Jack: No. They must get their work done before they use the laptop.
