International Space Station set to get urgent grocery delivery
The International Space Station is about to get some fresh groceries and material for an urgent repair job.
An unmanned SpaceX rocket is expected to blast off from Cape Canaveral at 4.58pm local time with more than two tons of supplies.
Nasa spent much of the weekend debating whether to proceed with the launch.
A critical back-up computer failed outside the space station on Friday. Mission managers decided yesterday to stick with the plan after making sure everything would be safe.
The Dragon supply ship holds a gasket-like material for next week's computer replacement. Space-walking astronauts will perform the job on April 22. This new material was rushed to the launch site following the computer failure.
SpaceX is one of two American shippers hired by Nasa.
