KENNEDY SPACE CENTER, Fla. – After completing a fueling test of its mega moon rocket earlier this week, NASA engineers now have to contend with Tropical Depression Nine that appears to be aimed at Florida.
NASA managers plan to provide an update on a possible launch attempt and the next steps for the SLS and Orion, which make up the Artemis-1 mission. The moon rocket is vertical at Kennedy Space Center launchpad 39B on Florida’s east coast, awaiting a third launch attempt.
After two previous scrubs due to unruly hydrogen leaks and an engine cooling issue, NASA fueled the SLS with more than 700,000 gallons of cryogenic propellant during a test Monday to determine if engineers had resolved the problems.
Overall, NASA management called the test a success.
Artemis-1 Launch Director Charlie Blackwell-Thompson said the tanking test, “went really well,” and NASA’s Associate Administrator for Exploration Systems Development Jim Free tweeted the team achieved, “all four test objectives,” and used new propellant loading procedures.
NASA is hoping to launch on Sept. 27 at 11:37 a.m. EDT. However, it’s not up to the space agency. NASA first needs approval from the Space Force, which oversees the Eastern Range, to extend the Flight Termination System certification due to safety requirements. The FTS is required on all rockets and would cause the vehicle to self-destruct if it veers off course and threatens the public.
The Sept. 27 launch date and a backup window on Oct. 2 are under review by the Space Force. NASA needs an answer soon if the agency is going to launch on Tuesday.
In the past week, the tropics have become full of activity after a slow start to the Atlantic hurricane season.
Launch weather officers with the Space Force 45th Weather Squadron will closely watch Tropical Depression Nine currently roaming the central Caribbean Sea about 600 miles east-southeast of Kingston, Jamaica.
On Friday, the 45th Weather Squadron released its first launch forecast for Sept. 27. Forecasters are predicting only a 20% chance of favorable weather for the 70-minute launch window.
According to the forecast, a front pushing into the Space Coast this weekend will bring rain and northeasterly winds and then Tropical Depression Nine, which could be a tropical storm soon, will gradually push more shower activity to the Space Coast.
“The weather begins to further deteriorate Monday into Tuesday, as a possible hurricane (TD 9) shifts into the northwest Caribbean Sea,” Launch officers wrote. “The official forecast from the National Hurricane Center tracks the possible hurricane over western Cuba early Tuesday, with the storm entering the eastern gulf near the Florida Keys mid-day Tuesday. Deep tropical moisture will spill across the Spaceport Tuesday, with widespread cloud cover and scattered showers likely during the launch window.”
This particular system will be a factor in any upcoming Artemis launch attempt because Tropical Depression Nine is forecast to become a tropical storm later Friday and strengthen into a hurricane and possibly make landfall on the Florida Peninsula early next week.
The latest cone of uncertainty covers the Florida Keys, South Florida and Central Florida, including NASA’s Kennedy Space Center.
If a tropical system does bring strong winds to Florida’s Space Coast, NASA would need to roll the 322-foot-tall rocket back into the Vehicle Assembly Building. That 2-mph move to the hangar cannot happen in winds over 46 mph.
