The Mobile Service Tower at Cape Canaveral's Complex 37B launch pad is in motion, revealing the 233-foot-tall Delta 4-Heavy rocket for liftoff at 3:33 a.m. EDT (0733 GMT) with NASA's Parker Solar Probe.

The mobile gantry -- which weighs in at around 9 million pounds -- is moving on rail tracks to a park position around 300 feet northeast of the launch mount at Complex 37B.

The structure provided weather protection for the Delta 4-Heavy, and access to the launch vehicle for engineers and technicians, since the rocket's rollout and erection at the launch pad in April.

The tower stands around 330 feet tall, and measures 90 feet wide and 40 feet deep. It was built before the first Delta 4 launch in 2002.

The next step in this evening's countdown will be final closeouts at the launch pad, before evacuation of workers to a safe fallback position ahead of the start of cryogenic tanking. Launch managers from United Launch Alliance and NASA will receive a weather briefing at around 10 p.m. EDT (0200 GMT), and fueling of the Delta 4-Heavy with liquid hydrogen and liquid oxygen should begin soon after 11 p.m. EDT (0300 GMT).

There remains a 70 percent probability of acceptable weather during Saturday's 65-minute launch window.

Launch weather officer Kathy Winters is now predicting an 80% chance of acceptable weather conditions for launch tonight. The only concerns are for anvil clouds. The countdown is currently in a planned hold at T-4 hours 15 minutes.
