Two US astronauts on Sunday stepped out on the third spacewalk to prepare the International Space Station for the arrival of more commercial spacecraft in the coming years. Barry Wilmore and Terry Virts began the spacewalk at 6:52 am (1152 GMT). During the six hour, 45 minute outing, they plan to set up antennas and communications equipment so that future crews launching from Florida on US commercial spacecraft will be able to park at the space station, NASA said. The spacewalk is the third in eight days for NASA, and is the 187th in the history of the space station.
Israeli Prime Minister Benjamin Netanyahu headed to Washington Sunday on what he said was a "historic" mission to try to stop a nuclear deal with Iran, an AFP correspondent reported. The controversial 48-hour visit will see the Israeli leader addressing a joint session of the US Congress in a bid to garner last-minute support to halt an emerging world deal with Iran over its nuclear programme, in a move which has infuriated the White House. "I'm going to Washington on a fateful, even historic, mission," he told reporters on the tarmac at Ben Gurion airport near Tel Aviv shortly before his plane took off.
