SpaceX was scheduled to attempt to land its Falcon 9 rocket on a floating barge in the Atlantic for the second time tonight, but the launch has been scrubbed because of issues with a first stage transmitter and a range radar. The launch has been postponed until tomorrow evening.

A successful landing would mean SpaceX would be able to reuse the rocket in future missions, which could save millions of dollars over time.

Update, February 9th, 10:32 AM: Due to inclement weather, the Falcon 9 launch has been postponed again, from Monday evening until Tuesday evening.
