SpaceX is set to launch a rocket before dawn on Thursday, March 19, from Launch Complex 40 at Cape Canaveral Space Force Station. The liftoff window opens at 6:35 a.m. and closes at 10:35 a.m., following delays caused by a storm earlier in the week. The mission, part of SpaceX's Starlink satellite program, marks the company's third launch this month from Florida. NASA's Space Launch System (SLS) rocket, standing 322 feet tall, is scheduled to roll out to the launch pad at Kennedy Space Center in Cape Canaveral later this month. This move is a key step for Artemis II, the first crewed lunar mission since 1972. The SLS, built specifically for NASA's lunar program, will carry astronauts around the moon before returning to Earth. The rollout is expected to occur in late March, with the mission targeting a 2027 launch. A previous SpaceX launch on March 19 was delayed by weather but successfully lifted off at 10:20 a.m. from the same launch site. The rocket carried 53 Starlink satellites to orbit, though visibility was limited by cloud cover in parts of Florida. Meanwhile, Titusville's American Space Museum is preparing for its third annual 321 Day festival on Saturday, March 21. The event will feature a countdown to 3:21 p.m. at Space View Park, near the museum, celebrating Brevard County's space heritage and its 321 area code. The festival runs from 11 a.m. to 5 p.m. and includes food trucks, exhibits, and space-themed activities. The event draws visitors from across the Space Coast, highlighting the region's role in space exploration. Both the SpaceX launch and NASA's Artemis II preparations underscore Florida's ongoing significance in the U.S. space program, with multiple launches and milestones expected in the coming months.
