Photos: Atlas 5 rocket aims for International Space Station

Northrop Grumman is gearing up for up to four launches this year at Wallops Island, Virginia, including two launches with Cygnus cargo ships heading to the International Space Station, and a pair of Minotaur rocket flights carrying classified payloads into orbit for the U.S. government’s spy satellite agency.

The unpiloted Russian Soyuz MS-14 spacecraft docked with the International Space Station on its second try at 11:08 p.m. EDT Monday (0308 GMT Tuesday), three days after aborting an approach due to a problem with the Kurs automated rendezvous system.

Two astronauts floated outside the International Space Station early Tuesday and replaced one of the grapple fixtures on the end of the lab’s robot arm, the first of two excursions over the next week to complete a complex overhaul that began with a pair of spacewalks last October.
