Culminating years of construction and testing, a $1.2 billion satellite designed to spot and track enemy missiles threatening the United States homeland, its deployed military forces abroad or allied nations will ascend to a surveillance post in space Thursday.

Engineers at NASA’s Kennedy Space Center tasked with overseeing launches of scientific satellites and interplanetary probes will be responsible later this year for ensuring six major missions safely get into space over a span of a little more than six months, beginning with the launch of NOAA’s new GOES-S weather observatory on an Atlas 5 rocket March 1.

A Russian cosmonaut, his Canadian co-pilot and a NASA flight engineer packed their Soyuz spacecraft for departure from the International Space Station Monday night, targeting a landing on the steppe of Kazakhstan to close out an action-packed 204-day mission.
