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.
