WATCH: SpaceX Rocket Launch Livestream

After a helium leak scrubbed the launch scheduled for April 14, SpaceX will attempt to launch their umanned Dragon cargo ship to the International Space Station on April 18.

This mission, set to lift off at 3:25 p.m. EDT, will re-supply the ISS and its crew. The player above will begin coverage of the event shortly before the scheduled launch time at 2:45.

SpaceX is owned by Elon Musk, formerly of PayPal. Musk is also the man who oversees Tesla Motors.

Items in this mission’s cargo include supplies for a space farm, microbes for experiments, and other supplies the astronauts need.

SpaceX has taken all the necessary precautions to ensure that today’s rescheduled flight goes off without a hitch:

“During Monday’s launch attempt, preflight checks detected that a helium valve in the stage separation pneumatic system was not holding the right pressure. This meant that the stage separation pistons would be reliant on a backup check valve. No issue was detected with the backup valve and a flight would likely have been successful, but SpaceX policy is not to launch with any known anomalies. We have brought the vehicle back to horizontal and are replacing the faulty valve, as well as inspecting the whole system for anything that may have contributed to the valve not working as designed.”
