On day 11 of the Artemis I mission, Orion continues its journey beyond the Moon after entering a distant retrograde orbit Friday, Nov. 25, at 3:52 p.m. CST. Orion will remain in this orbit for six days before exiting lunar orbit to put the spacecraft on a trajectory back to Earth and f a Sunday, Dec. 11, splashdown in the Pacific Ocean.

Orion surpassed the distance record for a mission with a spacecraft designed to carry humans to deep space and back to Earth, at 7:42 a.m. Saturday, Nov. 26. The record was set during the Apollo 13 mission at 248,655 miles from our home planet. At its maximum distance from the Moon, Orion will be more than 270,000 miles from Earth Monday, Nov. 28.

Engineers also completed the first orbital maintenance burn by firing auxiliary thrusters on Orion’s service module at 3:52 p.m. for less than a second to propel the spacecraft at .47 feet per second. The planned orbital maintenance burns will fine-tune Orion’s trajectory as it continues its orbit around the Moon.

Flying aboard Orion on the Artemis I mission is a suited manikin named after a key player in bringing Apollo 13 safely back to Earth. Arturo Campos was an electrical engineer who developed a plan to provide the command module with enough electrical power to navigate home safely after an oxygen tank aboard the service module of the Apollo spacecraft ruptured. Commander Moonikin Campos is outfitted with sensors to provide data on what crew members may experience in flight, continuing Campos’ legacy of enabling human exploration in deep space.

Artemis builds on the experience of Apollo. With Artemis, humans will return to the lunar surface, and this time to stay. NASA will use innovate technologies to explore the Moon’s South Pole and more of the lunar surface than ever before using the Gateway space station in lunar orbit along with advanced spacesuits and rovers. NASA will lead the way in collaboration with international and commercial partners to establish the first long-term presence on the Moon. Then, we will use what we learn on and around the Moon to take the next giant leap: sending the first astronauts to Mars.

As of 1:16 p.m., Orion was 252,133 miles from Earth and 52,707 miles from the Moon, cruising at 2,013 miles per hour. You can track Orion via the Artemis Real-Time Orbit Website, or AROW.

NASA’s Mission Control Center at the agency’s Johnson Space Center in Houston unexpectedly lost data to and from the spacecraft at 12:09 a.m. CST for 47 minutes while reconfiguring the communication link between Orion and Deep Space Network overnight. The reconfiguration has been conducted successfully several times in the last few days, and the team is investigating the cause of the loss of signal. The team resolved the issue with a reconfiguration on the ground side. Engineers are examining data from the event to help determine what happened, and the command and data handling officer will be downlinking data recorded onboard Orion during the outage to include in that assessment. There was no impact to Orion, and the spacecraft remains in a healthy configuration.

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.

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.

NASA is working with U.S. Space Force and the National Hurricane Center to monitor Subtropical Storm Nicole. NASA’s Kennedy Space Center in Florida is currently in a HURCON (Hurricane Condition) IV status, which includes implementing checklists and preparations for the storm as the agency continues to prioritize its employees in the Kennedy area. Based on current forecast data, managers have determined the Space Launch System rocket and Orion will remain at Launch Pad 39B. Teams at Kennedy will continue to monitor the weather, make sure all personnel are safe, and will evaluate the status of the Monday, Nov. 14, launch attempt for the Artemis I mission as we proceed and receive updated predictions about the weather.

NASA is targeting the next launch attempt of the Artemis I mission for Monday, Nov. 14 with liftoff of the Space Launch System (SLS) rocket carrying the Orion spacecraft planned during a 69-minute launch window that opens at 12:07 a.m. EST. Artemis I is an uncrewed flight test to launch SLS and send Orion around the Moon and back to Earth to thoroughly test its system before flights with astronauts. 

Inspections and analyses over the previous week have confirmed minimal work is required to prepare the rocket and spacecraft to roll out to Launch Pad 39B at Kennedy Space Center in Florida following the roll-back due to Hurricane Ian.  Teams will perform standard maintenance to repair minor damage to the foam and cork on the thermal protection system and recharge or replace batteries on the rocket, several secondary payloads, and the flight termination system. The agency plans to roll the rocket back to the launch pad as early as Friday, Nov. 4. 

NASA has requested back-up launch opportunities for Wednesday, Nov. 16, at 1:04 a.m. and Saturday, Nov. 19, at 1:45 a.m., which are both two-hour launch windows. A launch on Nov. 14 would result in a mission duration of about 25-and-a-half days with a splashdown in the Pacific Ocean Friday, Dec. 9. 

Engineers at NASA’s Kennedy Space Center in Florida are in the process of preparing the Space Launch System (SLS) rocket and Orion spacecraft for the next launch attempt in November for the Artemis I mission. Check-outs conducted this week will allow NASA to finalize the work schedule before rolling SLS and Orion back to Launch Pad 39B.

Since resuming work after Hurricane Ian, teams have extended work platforms around SLS and Orion to assess the exterior and access internal components. Exterior inspections will note any foam or cork from the thermal protection system on the rocket or spacecraft that might need to be repaired. Teams will replace the flight batteries for the interim cryogenic propulsion stage and the boosters, as well as the batteries for the flight termination system in the boosters and core stage.

Work will also include charging the CubeSats that are equipped to be re-charged and have elected to do so. Inside Orion, work will include replenishing the specimens and batteries for the biology investigations riding within the capsule, as well as recharging the batteries associated with the crew seat accelerometers and space radiation experiments.

While teams inside the Vehicle Assemble Building complete check-outs, managers are coordinating with the U.S. Space Force to reserve launch dates on the Eastern Range and working with other parts of the agency to evaluate any potential constraints before NASA sets a target date for the next launch attempt.

Although the Kennedy area received minimal impacts from Hurricane Ian, many team members who live farther west experienced larger effects from the storm and are still recovering. Managers are working with teams to ensure they have the time and support needed to address the needs of their families and homes.

Teams at NASA’s Kennedy Space Center in Florida conducted initial inspections Friday to assess potential impacts from Hurricane Ian. There was no damage to Artemis flight hardware, and facilities are in good shape with only minor water intrusion identified in a few locations. Next, engineers will extend access platforms around the Space Launch System rocket and Orion spacecraft inside the Vehicle Assembly Building (VAB) to prepare for additional inspections and start preparation for the next launch attempt, including retesting the flight termination system.

As teams complete post-storm recovery operations, NASA has determined it will focus Artemis I launch planning efforts on the launch period that opens Nov. 12 and closes Nov. 27. Over the coming days, managers will assess the scope of work to perform while in the VAB and identify a specific date for the next launch attempt. Focusing efforts on the November launch period allows time for employees at Kennedy to address the needs of their families and homes after the storm and for teams to identify additional checkouts needed before returning to the pad for launch.

With the Artemis I Space Launch System rocket and Orion spacecraft safety in the Vehicle Assembly Building after rolling back from Launch Pad 39B Monday night, NASA continues to prioritize its employees as Hurricane Ian approaches the Kennedy Space Center area. 

As part of NASA’s hurricane preparedness protocol, a “ride out” team will remain in a safe location at Kennedy throughout the storm to monitor centerwide conditions. After the storm passes, they will conduct an assessment of facilities, property, and equipment. Once it is safe for additional employees to return to Kennedy, engineers will extend platforms to establish access to the rocket and spacecraft.  

Managers will review options on the extent of work that will be conducted in the VAB before returning to the launch pad or identifying the next opportunity for launch. Technicians will swap out batteries on the rocket’s flight termination system and retest the system prior to the next launch attempt. 

NASA will roll the Artemis I Space Launch System rocket and Orion spacecraft back to the Vehicle Assembly Building on Monday, Sept. 26. First motion is targeted for 11 p.m. EDT.

Managers met Monday morning and made the decision based on the latest weather predictions associated with Hurricane Ian, after additional data gathered overnight did not show improving expected conditions for the Kennedy Space Center area. The decision allows time for employees to address the needs of their families and protect the integrated rocket and spacecraft system. The time of first motion also is based on the best predicted conditions for rollback to meet weather criteria for the move.

NASA has continued 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.

NASA continues to provide a live stream of the rocket and spacecraft on the launch pad.
