NASA Prepares Rocket, Spacecraft Ahead of Tropical Storm Nicole, Re-targets Launch



NASA is continuing to monitor Tropical Storm Nicole and has decided to re-target a launch for the Artemis I mission for Wednesday, Nov. 16, pending safe conditions for employees to return to work, as well as inspections after the storm has passed. Adjusting the target launch date will allow the workforce to tend to the needs of their families and homes, and provide sufficient logistical time to get back into launch status following the storm.


Kennedy currently is in a HURCON (Hurricane Condition) III status, which includes securing facilities, property and equipment at the center, as well as briefing and deploying the “ride-out” team. As part of NASA’s hurricane preparedness protocol, a “ride-out” team includes a set of personnel who will remain in a safe location at Kennedy throughout the storm to monitor centerwide conditions, including the flight hardware for the Artemis I mission. Kennedy will release non-essential personnel at the HURCON II status as the agency continues to prioritize its employees in the Kennedy area.


Based on expected weather conditions and options to roll back ahead of the storm, the agency determined Sunday evening the safest option for the launch hardware was to keep the Space Launch System (SLS) rocket and Orion spacecraft secured at the pad.


The SLS rocket is designed to withstand 85 mph (74.4 knot) winds at the 60-foot level with structural margin. Current forecasts predict the greatest risks at the pad are high winds that are not expected to exceed the SLS design. The rocket is designed to withstand heavy rains at the launch pad and the spacecraft hatches have been secured to prevent water intrusion.


In preparation for the storm, teams have powered down the Orion spacecraft, SLS core stage, interim cryogenic propulsion stage, and boosters. Engineers have also installed a hard cover over the launch abort system window, retracted and secured the crew access arm on the mobile launcher and configured the settings for the environmental control system on the spacecraft and rocket elements. Teams also are securing nearby hardware and performing walkdowns for potential debris in the area.


Teams are poised to resume work as soon as weather and Kennedy center status allows. Once back on-site, technicians will perform walkdowns and inspections at the pad to assess the status of the rocket and spacecraft as soon as practicable.


A launch during a two-hour window that opens at 1:04 a.m. EST on Nov. 16 would result in a splashdown on Sunday, Dec. 11. If needed, NASA has a back-up launch opportunity on Saturday, Nov. 19, and will coordinate with the U.S. Space Force for additional launch opportunities.


The agency continues to rely on the most up to date information from the National Oceanic and Atmospheric Administration, U.S. Space Force, and the National Hurricane Center throughout its evaluations and continues to closely monitor conditions for the Kennedy area.
 
Teams Conduct Check-outs, Preparations Ahead of Next Artemis I Launch Attempt

NASA continues to target launch of its Artemis I mission from the agency’s Kennedy Space Center in Florida at 1:04 a.m. EST, Wednesday, Nov. 16. There is a two-hour launch window for the agency’s first integrated flight test of its Space Launch System (SLS) rocket and Orion spacecraft.


Teams conducted thorough assessments at Launch Complex 39B beginning Thursday evening, closely inspecting SLS, Orion, mobile launcher, and other pad-related assets to confirm there were no significant impacts from Hurricane Nicole, which made landfall more than 70 miles south of the launch pad. The physical inspections augmented remote monitoring via sensors and high-resolution cameras performed during the storm by a team in a safe location at Kennedy.


Space Launch System engineers have performed detailed analysis to confirm the sustained and peak winds experienced during the storm have no adverse effect on the structural strength of the rocket. While varying peak winds were measured by sensors at different heights at the pad, all measurements remained below 75% of SLS design limits, which also are intentionally conservative. Data from testing with actual hardware during the structural test series and modal testing, as well as other evaluations and modeling, provide confidence there is margin beyond the design ratings.


Technicians also are working to fix several minor items from the storm. Most repairs involve loose caulk or weather coverings. An umbilical used to provide purge air, or proper environmental conditions to the Orion spacecraft, was out of position. The umbilical maintained purge throughout the storm and has been repositioned to allow proper retraction at liftoff. Engineers have also removed the hard cover over the launch abort system window installed before the storm and will inspect the window to confirm it is in good condition for launch.


Today, as part of normal launch preparation, engineers are in the process of powering up rocket and spacecraft elements to confirm all systems are healthy. Powered health checks will continue until Saturday. Engineers plan to conduct the standard final software and hardware-related tests required before launch, on Sunday. The Artemis I mission management team will convene Sunday afternoon to review the preparations for launch.
 
CAPSTONE Arrives to Orbit at the Moon


The CAPSTONE mission operations team confirmed that NASA’s CAPSTONE spacecraft arrived at its orbit at the Moon Sunday evening. The CubeSat completed an initial orbit insertion maneuver, firing its thrusters to put the spacecraft into orbit, at 7:39 p.m. EST.


CAPSTONE is now in a near-rectilinear halo orbit, or NRHO. This particular NRHO is the same orbit that will be used by Gateway, the Moon-orbiting space station that will support NASA’s Artemis missions. CAPSTONE is the first spacecraft to fly an NRHO, and the first CubeSat to operate at the Moon.


In the next five days, CAPSTONE will perform two additional clean-up maneuvers to refine its orbit. After these maneuvers, the team will review data to confirm that CAPSTONE remains on track in the NRHO.



Il Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) è un orbiter lunare che è stato lanciato il 28 giugno 2022, il suo scopo è di verificare la stabilità dell'orbita in cui verrà posizionato il Lunar gateway. Inoltre la sonda ha lo scopo di testare alcune tecnologie innovative per determinare la sua posizione senza l'ausilio di sistemi da terra, ma utilizzando il Lunar Reconnaissance orbiter (LRO) come punto di riferimento
 
Managers Proceed Toward Nov. 16 Launch, to Meet Monday


The Artemis I mission management team met Sunday evening to review the status of preparations for launch and gave a “go” to proceed toward a Nov. 16 launch attempt. The team will meet again Monday afternoon to review additional analysis associated with caulk on Orion’s launch abort system that came loose during Hurricane Nicole. The two-hour window for launch opens at 1:04 a.m. EST Wednesday. The countdown clock will begin at 1:54 a.m. Monday.


Within the next day, engineers will conduct detailed analysis of several feet of delaminated caulk where the ogive on Orion’s launch abort system meets the crew module adapter. The analysis will assess risk should it come loose during launch.


Overnight, in parallel with launch preparations, technicians also will remove and replace a component of an electrical connector on the hydrogen tail service mast umbilical ground-side plate. Engineers continue to see some inconsistent data provided through the connector, despite replacing the cable to the connector earlier in the week. Engineers have redundant sources for the information provided through the connector and it is not an impediment to launch.


NASA will provide a prelaunch status update Monday afternoon after the mission management team reconvenes.


Live coverage of tanking operations with commentary on NASA TV will begin on Tues., Nov. 15 at 3:30 p.m. EST. Full launch coverage in English will begin at 10:30 p.m. and NASA en espanol broadcast coverage will begin at 12 a.m. Wednesday.
