Zitat NASA's Kennedy Space Center @NASAKennedy Kennedy is in a HURICON III status and continues to prep for the upcoming storm taking prudent precautions across all of our programs, activities, and workforce in advance of the storm.
HURCON IV: 72 hours prior to 50-knot sustained winds. This initial notification and preparation phase includes implementing organization-specific checklists, ensuring all government-owned vehicles and General Services Administration vehicles are fully fueled, and confirming Rideout Team (ROT) personnel. HURCON III: 48 hours prior to 50-knot sustained winds. Primary actions include securing facilities, property and equipment, as well as briefing and deploying the ROT. HURCON II: 24 hours prior to 50-knot sustained winds. All securing actions are completed or terminated; non-ROT personnel are released, and ROT personnel are sheltered. HURCON I: 12 hours prior to 50-knot sustained winds. Kennedy remains closed, all perimeter gates closed, ROT is sheltered at designated locations.

Confidence is pretty high in the track now, although some subtle chances are definitely possible. Bigger question is intensity, although no serious modeling is suggesting this gets stronger than a Category 1 storm. 6:20 PM · Nov 8, 2022·TweetDeck
Stephen C. Smith / Нет войне 🇺🇦 @WordsmithFL·20m Replying to @SciGuySpace Sustained winds for north Merritt Island, Cocoa Beach, Titusville all showing a peak of 42-45 MPH around sunrise on Thursday. No doubt we'll have stronger gusts, but I haven't seen anything on http://Weather.com's hourly forecast suggesting 75 MPH+ sustained winds.
Eric Berger@SciGuySpace·19m Replying to @WordsmithFL That's because http://weather.com's forecast does not reflect the considerable uncertainty in wind forecasts of this nature. 45 mph is probably the best bet, but it's just in the middle of a fat curve.

Zitat Tropical storm delays next Artemis 1 launch attempt
NASA is postponing the next Artemis 1 launch attempt by at least two days as a tropical storm, forecast to become a hurricane, approaches the Florida coast.
NASA announced late Nov. 8 that it would no longer pursue a launch of the Space Launch System rocket and Orion spacecraft from the Kennedy Space Center on Nov. 14. Before the announcement, NASA had been working towards a launch of the Artemis 1 mission at 12:07 a.m. Eastern that day, at the opening of a 69-minute window.
The agency said the slip will give personnel time to prepare for the approaching Tropical Storm Nicole, currently in the Atlantic Ocean heading west towards the east coast of Florida. Forecasts from the National Hurricane Center predict the storm will strengthen into a hurricane before reaching the coast south of KSC early Nov. 10.
Despite the approaching storm, NASA will keep SLS on the pad at Launch Complex 39B, where it rolled out early Nov. 4. Agency officials said in a briefing the day before the rollout that they were tracking the potential for the formation of a tropical storm but concluded that even if the storm developed, it would not be strong enough to damage the vehicle.
NASA said that assessment is still valid even though the storm is forecast to be stronger that previously predicted. “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,” NASA said in a statement announcing the delay. ... With the Nov. 14 launch opportunity ruled out, the next possible launch date is Nov. 16, with a two-hour window opening at 1:04 a.m. Eastern. Another launch window, also two hour long, opens at 1:45 a.m. Eastern Nov. 19. Those dates, NASA said, will depend on the status of SLS and Orion, and KSC overall, after the storm passes.
The current launch period runs through Nov. 27, although there are no launch opportunities Nov. 20 or 21, as well as Nov. 26, because of Orion performance constraints. Agency officials earlier said that launches on the remaining days would be difficult because of the high air traffic during the Thanksgiving holiday, but had tentatively identified Nov. 25 as a potential launch date if Artemis 1 does not launch by Nov. 19.
If Artemis 1 does not launch in November, the next launch period opens Dec. 9 and runs through Dec. 22.
Ich führe schon gar keinen Countdown mehr, sondern nur noch eine Strichliste nach dem Motto: "mal sehen, wie lange es dauert, bis das in die nächste Verlängerung geht." Und die nächste. Und die nächste.

Zitat Everyday Astronaut @Erdayastronaut I don’t expect to get a solid confirmation on the state of SLS/Orion until the teams can get back out to the pad & do a handful of inspections. Due to the days that crews have been unable to prep for launch, the 16th is highly unlikely. Now we wait on the status & plan! 8:03 PM · Nov 10, 2022·Twitter for iPhone

Zitat NASA assesses moon rocket after a brush with Hurricane Nicole
NASA’s $4.1 billion Artemis moon rocket, exposed to the elements atop its Kennedy Space Center launch pad, was rocked by high winds and driving rain early Thursday as Hurricane Nicole roared ashore just south of the spaceport.
With blastoff on a long-delayed maiden flight on tap next week, sensors at pad 39B recorded gusts as high as 100 miles per hour atop a 467-foot-tall lightning tower near the rocket. But winds at the 60-foot-level of the launch gantry, which are part of the booster’s structural certification, peaked at 82 mph, just below the 85 mph limit.
The observed winds were “within the rocket’s capability,” said Jim Free, manager of exploration systems at NASA Headquarters. “We anticipate clearing the vehicle for those conditions shortly.”
“Our team is conducting initial visual check outs of the rocket, spacecraft and ground system equipment with the cameras at the launch pad,” he said in a Twitter post. “Camera inspections show very minor damage such as loose caulk and tears in weather coverings. The team will conduct additional on-site walk down inspections of the vehicle soon.”
In any case, the 322-foot-tall Space Launch System rocket appeared to weather the storm with no obvious signs of trouble, held solidly in place by a sturdy stabilizer extending from its mobile launch gantry, along with eight massive bolts, four at the base of each of its two solid-fuel boosters, that hold the rocket down before liftoff. ... In the meantime, engineers reviewed telemetry from a variety of sensors, including strain gauges on the hold-down bolts and stabilizer to determine the forces acting on the huge rocket.
“The SLS rocket is designed to withstand 85-mph winds at the 60-foot level with structural margin,” NASA said in a November 8 blog post.
Data on a NASA web page showing wind speeds at various points on and around pad 39B showed gusts exceeding 85 mph, including the 100-mph reading, but it wasn’t immediately clear how those readings fit into NASA’s safety guidelines. A wind gauge on the roof of the CBS News bureau 4.2 miles from the pad registered gusts as high as 87 mph ... If no major problems are found in the wake of Nicole, and if senior managers decide to press ahead, countdown clocks will start ticking at 1:54 a.m. EST Monday, setting up a launch attempt at 1:04 a.m. Wednesday.
The SLS rocket was first rolled to the pad for an initial fueling test last March, some 238 days ago, and has now made seven trips to and from the Vehicle Assembly Building while engineers dealt with multiple fuel leaks and unrelated glitches.
Zitat DNail @DerrolNail Finally, some good launch weather for #Artemis: 80% GO for launch on Wednesday 11/16 at 1:04am ET. Only concern for low probability of violation is cumulus cloud rule 4:15 PM · Nov 12, 2022 ·Twitter for iPhone
Zitat NASA managers cleared the agency’s leak-bedeviled Artemis moon rocket for the start of another countdown early Monday, but engineers must resolve questions about hurricane-damaged insulation before the huge booster can be cleared for blastoff on an unpiloted moonshot.
After multiple delays due to hydrogen fuel leaks and other glitches, along with the rocket’s nail-biting brush with Hurricane Nicole last week, NASA managers met Sunday to review launch preparations and agreed to start a 47-hour 10-minute countdown at 1:54 a.m. EST Monday. Launch is planned for 1:04 a.m. Wednesday. ... If all goes well, the launch team will begin pumping 750,000 gallons of supercold liquid oxygen and hydrogen fuel back into the huge rocket’s tanks starting just before 4 p.m. Tuesday, using revised “kindler, gentler” techniques to control temperatures and minimize sharp pressure jumps to prevent leaks in critical seals.
If any problems do show up, engineers will have two hours to resolve them before the launch window closes.
Zitat Eric Berger @SciGuySpace They're going. Or at least will try to.
Zitat Jim Free@JimFree·10h Coming up at 8:30PM ET on http://nasa.gov/live, hear from members of our #Artemis I team about progress toward the launch of our flight test. Lift-off is targeted for November 16 at 1:04AM ET.
Free also said the CAPSTONE spacecraft hjs successfully been inserted into near-rectilinear halo orbit! Great progress by the public-private mission. Will fly in this orbit for the next six months.
NASA's Jim Free says preparation for the Artemis I launch attempt on Wednesday, at 1:04am ET (06:04 UTC) is proceeding as normal.
According to Sarafin this RTV material is there to essentially fill in a small gap in the Orion spacecraft where there otherwise would be some aero heating. Not an insulation concern. Does not sound like an issue that some of it has come off.
"We do not have access to repair this at the pad," Sarafin said. But not concerned about "liberated debris" hitting critical components during launch.
NASA's Mike Sarafin says the area of insulation that peeled away from Orion during Hurricane Nicole is about 10 feet in length, and it is a "very very thin layer" about 0.2 to inches thick.
Zitat von November 13, 2022 10:01 pmThe 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.
Zitat Advanced Space@AdvancedSpace #CAPSTONE is at the #Moon! Initial data indicates that insertion into Near Rectilinear Halo Orbit (NRHO) was executed as planned.

Vier Monate dauerte die Reise - jetzt hat der Satellit "Capstone" die Umlaufbahn des Mondes erreicht. Der NASA-Flugkörper von der Größe einer Mikrowelle testet die Bedingungen für die Raumstation "Gateway".
Der NASA-Satellit "Capstone" hat vier Monate nach dem Start von einem Weltraumbahnhof in Neuseeland sein Ziel am Mond erreicht. Der Mini-Satellit sei in die vorgesehene Umlaufbahn des Mondes eingeschwenkt, teilte die US-Raumfahrtbehörde NASA mit.
Der Flugkörper von der Größe einer Mikrowelle soll den Mond nun genau auf der Umlaufbahn umkreisen, die für die geplante Raumstation "Gateway" vorgesehen ist. Auf diese Weise sollen mögliche Risiken für die Station schon im Vorfeld ausgeschlossen werden.

Tonight, all flight batteries get charged and pressurizing the core stage COPVs and final walk downs and final comms checkouts with Orion. 4/x. All personnel clear of Blast Danger Area by 2:04 PM EST Tuesday ahead of tanking. 5/x. 17 minutes added to LH2 chilldown timeline, and about 35 minutes added time for LH2 fast fill. 6/x. The J8 electrical/data connector update. Retests are complete. The issue seen after Nicole: at powerup, readings were not as expected, but then came into line with expectations. After retests today, team unanimously decided they were in a good position to proceed to launch 7/x: RTV issue on Orion cleared for launch after the further review the team wanted yesterday. 8/x. Risks of liberation during flight still within the acceptable limits discussed and accepted at Flight Readiness Review. 9/x: There were no dissenting opinions on accepting the RTV issue as is. 10/x. They are still seeing "funny" noise in the LH2 umbilical electrical/data line after retests, but redundancies in place for tomorrow. 11/x. "Tomorrow" at this point just means "launch day" giving timings 12/x. Per RTV, there is a small chance more RTV could come off, but flight rationale supports this risk. In order for it to cause an issue in flight, it would have to liberate and hit a critical area. NASA feels if more liberates, it will tear apart in small pieces. 13/x. NASA will allow short-term breaches of the 4% ambient hydrogen during transition phases as they did during the Sept. 21st fueling test. 14/x. Per RTV, NASA says, based on atmospheric pressure decrease with altitude increase, that there is a "small aerodynamic window of concern" for RTV delamination and impact downstream on the vehicle. 12:31 AM · Nov 15, 2022·Twitter Web App
Zitat Jeff Foust @jeff_foust Mike Sarafin, Artemis 1 mission manager, said analysis on the Orion RTV delimitation showed risk was bounded by current hazards. No dissenting opinions at the mission management team meeting. Sarafin adds that they’re “comfortable flying as-is” with both the RTV issue and the electrical connector on the tail service mast umbilical where they’re still “seeing some funnies” but have redundancy. Sarafin says, regarding the 10 cubesat secondary payloads, that there’s only one that has a low state of change that is of concern; he doesn’t name it but describes it as one mapping lunar volatiles (LunaH-Map?) 1:16 AM · Nov 15, 2022·Tweetbot for Mac

T minus 7 Stunden 50 Minuten. Seit 2 Stunden ist der Countdown bei 6:40 angehalten; es handelt sich um einen planmäßigen Zählstop von 3 Stunden.
Amerika started eine Rakete, um in ein paar Jahren wieder Menschen auf dem Mond zu laden. Am selben Tag startet Russland fast 100 Raketen, um die Stromversorgung eines Landes, das es überfallen hat & gegen das es militärisch verliert, zu zerstören. Mehr muß man über beide Länder nicht wissen.
