Two NASA astronauts and an Italian flight engineer are sheltering in the space station’s Russian segment as mission control analyzes a possible leak of toxic ammonia coolant aboard the complex.

NASA astronaut Jessica Meir took control of the International Space Station’s Canadian-built robot arm Monday to capture a Northrop Grumman Cygnus supply ship carrying crew provisions, spacewalking gear to repair an aging particle physics experiment, tech demo satellites for the U.S. military, and an oven to bake the first cookies in space.

Eight more satellites for Europe’s Galileo navigation fleet will be built by Germany’s OHB System AG and Britain’s Surrey Satellite Technology Ltd. under a contract worth more than $350 million.
