Russian engineers assessing leak from Soyuz crew spacecraft
A Russian Soyuz crew ferry ship docked to the International Space Station spewed particles of an unknown substance, presumably coolant fluid, into space Wednesday night, forcing two Russian cosmonauts to call off a planned spacewalk as engineers on the ground scrambled to determine the source and the effects of the leak.

After a launch attempt earlier in the week was scrubbed due to bad weather, SpaceX sent a Dragon cargo capsule toward the International Space Station Saturday with nearly four tons of supplies and experiments. Liftoff on a Falcon 9 rocket from Kennedy Space Center occurred at 2:20 p.m. EST (1920 GMT).
