Two astronauts who survived a dramatic launch mishap in October said on Wednesday they were confident this time about reaching the International Space Station, though they said a small fault had been discovered on their rocket during final checks.

Russian cosmonaut Alexei Ovchinin and U.S. astronauts Nick Hague and Christina Koch are due to blast off from the Baikonur Cosmodrome, Kazakhstan, at 12:14 a.m. local time on March 15.

For Ovchinin and Hague, it will be the first flight since a sensor failure two minutes after they blasted off in a similar launch on Oct. 11 forced them to perform an emergency landing.
