Japanese auto giant Toyota Motor engineer Fuminori Kataoka chats with humanoid robot Kirobo in Tokyo on June 26, 2013. A small humanoid robot Kirobo which can talk will be sent into space to provide conversational company for a Japanese astronaut in the international space station on a six-month mission from this August. - 

This final note: You can look forward to the first conversation between a human and a robot in space.

That's right. It's happening. This fall, a "humanoid communication robot" called Kirobo will travel to the International Space Station.

He, or she, or it, is about a foot tall. Kirobo "speaks" Japanese. Its mission is to keep astronauts company.

It can get lonely out there.
