SpaceX will try again Tuesday to land a booster rocket on a barge in the Atlantic Ocean.
The daring feat would have been part of a launch that was to deliver 4,000 pounds of cargo to the International Space Station.
But the launch was scrubbed due to weather.
If SpaceX can land its Falcon 9 rocket on the unmanned barge it would revolutionize space flight. That’s because it would dramatically cut costs. Previous attempts have failed.
