"The threat at this moment in time has been considered high enough based on all these inputs that it's just the right thing to roll back," Dr. Z said, adding this sets up #Artemis1 for a mid-to-late November launch.
NASA will host a Flight Readiness Review (FRR) media teleconference on Monday, Sept. 26, in preparation for the fifth crew rotation mission with SpaceX as part of the agency’s Commercial Crew Program.
NASA and SpaceX continue to target no earlier than 12:46 p.m. EDT, Monday, Oct. 3, for launch of the agency’s Crew-5 mission to the International Space Station from NASA’s Kennedy Space Center in Florida.
The mission will carry NASA astronauts Nicole Aunapu Mann and Josh Cassada, who will serve as mission commander and pilot, respectively, along with JAXA (Japan Aerospace Exploration Agency) astronaut Koichi Wakata, and Roscosmos cosmonaut Anna Kikina, who will serve as mission specialists.
These crewmates will travel to the space station for a six-month science and technology research mission. Plans also continue to return NASA’s SpaceX Crew-4 astronauts following a short handover on the space station with Crew-5.
Today’s FRR starts at approximately 4:30 p.m. EDT and includes the following participants:
Kathryn Lueders, associate administrator, Space Operations Mission Directorate, NASA Headquarters Steve Stich, manager, Commercial Crew Program, NASA Kennedy Joel Montalbano, manager, International Space Station, NASA’s Johnson Space Center Emily Nelson, chief flight director, Flight Operations Directorate, NASA Johnson William Gerstenmaier, vice president, Build and Flight Reliability, SpaceX Junichi Sakai, manager, International Space Station Program, JAXA Sergei Krikalev, executive director, Human Space Flight Programs, Roscosmos
Foams and Emulsions: The final day of the Experiment 2 science sessions was performed, but despite multiple attempts, a suitable foam was not able to be generated. The ground team believes the chip in the system may be faulty. Foams (dispersions of bubbles in a liquid) and emulsions (dispersions of droplets in a liquid) appear in many food, consumer, and personal care products and are used in a variety of industries. Structure and Stability of Foams and Emulsions examines the properties and performance of foams and emulsions, including using particles of various shapes and surface roughness to stabilize these materials. Microgravity enables examination of the microstructures of foams and emulsions due to the elimination of the influence of gravity-related factors such as buoyancy of particles.
Food Physiology: A diet briefing was attended between the crew and Principal Investigator team in support of the Food Physiology investigation. The Food Physiology experiment is designed to characterize the key effects of an enhanced spaceflight diet on immune function, the gut microbiome, and nutritional status indicators. These factors are interlinked, but diet is the only one that can be easily and meaningfully altered on Earth or during flight. This investigation aims to document the effect of dietary improvements on human physiology and the ability of those improvements to enhance adaptation to spaceflight.
eXposed Root On-Orbit Test System (XROOTS): Following the initiation of the 4th planting for the XROOTS experiment on Tuesday, the crew performed fluid management and wick opening. The wick opening allows the seeds to be assessed for germination and gives them more room to grow during the growth cycle. Over the next 30+ days, the crew will observe and assist with the seed germination and growout of the plants. The fourth planting includes Mizuna, Cherry Belle, Hakurei, and Tokyo Bekana. The XROOTS investigation uses hydroponic and aeroponic techniques to grow plants without soil or other growth media. Video and still images enable evaluation of multiple independent growth chambers for the entire plant life cycle from seed germination through maturity. Results could identify suitable methods to produce crops on a larger scale for future space missions.
Mobile Servicing System (MSS) Remote Power Control Module (RPCM) Firmware Load: As part of robotic activity, the ground teams successfully completed the MSS RPCM S12B-A Firmware Load and Pre-Position. The Cargo Transport Container J (CTC-J) RPCM was removed from into the S12B_A slot and inserted into the CTC-J slot. The CTC-A RPCM was removed from into the CTC-A slot and inserted into the S12B_A slot.
Crew Quarters (CQ) Cleaning: As part of in-flight maintenance, the crew cleaned the intake and exhaust ducts, fans, and airflow sensors in the Overhead Crew Quarters. Due to the large amounts of dust seen during previous CQ cleanings, the crew removed all relevant panels and temporarily stowed them to clean all areas at once.
ISS Crew Handover and Adaptation: The experienced 67S and Freedom crewmembers continued handover with the newly arrived 68S crew to transfer knowledge of the intricacies of onboard equipment and working in microgravity. The newly arrived crew member executed activities and the experienced crew member provided oversight and assistance. Today, the 68S crew were trained on the emergency roles and responsibilities to achieve a safe configuration on station.
Food Consolidate: Today, the crew consolidated the NOD1 food pantry to ensure the crew has easy access to food while also helping to reduce the overall stowage footprint in the Permanent Multipurpose Module (PMM). Crew time is often allocated toward stowage management to maintain safety, organization, and habitability.
Intermodule Ventilation (IMV) Fan Cleaning: Today, the crew inspected and cleaned the LAB Forward Port IMV Screen, IMV Fan, and Lower Flex Duct Inlet to improve airflow. The IMV flow rates should be sufficient to ensure that the IMV fan is operating outside of the stall region which causes a reduction of airflow and an increase fan acoustic noise. Excessive dust buildup can cause this phenomenon.

Today’s Ground Activities: All activities are complete unless otherwise noted.

The entire argument that total elapsed mission time equates to linear unmitigated risk rests on the assumption of not sending sufficient medical equipment and personnel to treat problems in situ. This is reasonable for lunar missions, MAYBE, but utterly unacceptable for Mars missions.
