HAWTHORNE -- Hawthorne-based SpaceX will make a fourth attempt today to launch a Falcon 9 rocket that will carry a communications satellite into orbit, with crews then expected to try again to recover the rocket on a floating barge.
The mission was scrubbed twice last week, then again earlier this week, because of a number of issues, including trouble with the liquid oxygen aboard the rocket, high winds, and a boat that floated into restricted waters off the coast of Cape Canaveral, Florida.
