Unprecedented space walk this week: "For the first time, the crew of the International Space Station will conduct a spacewalk without anyone inside to help them, officials in Houston say.

"Unlike the previous 26 excursions from the station, Thursday's 5-hour 45-minute spacewalk will not have a crew member inside tending the station."
