Rocket maker SpaceX is targeting Friday as the launch date for the next NASA cargo resupply flight to the International Space Station.
The Hawthorne company, owned by Tesla co-founder Elon Musk, performed a successful resupply mission to the space station in October and a demonstration mission in May.
SpaceX is the only commercial company to perform such a task.
Its Falcon 9 rocket is scheduled for blastoff Friday morning from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
During the mission, SpaceX's Dragon capsule is set to be packed with more than 1,200 pounds of scientific experiments and cargo for the astronauts aboard the space station. It will remain attached to the orbiting outpost for more than three weeks and return with more than 2,300 pounds of cargo.
The capsule is slated to splash down in the Pacific Ocean off Baja California on March 25.
SpaceX has secured a $1.6 billion contract to carry out 12 such cargo missions, and Friday's mission would be the second.
If the rocket launch is delayed, a backup date is available March 2.
