In March, we sprang forward across the factory floor, test stand, and launch pad.
🏗️ Build: Stage 1 downcomer fully welded and began acceptance testing, while stage 2 tank integration nears completion with the LOX lid, thrust cone, and headband installed
🔥 Test: Aeon V completed a 526.5-second endurance demonstration as Aeon R acceptance testing continues at NASA Stennis
🌴 Launch: At LC-16, rails between the HIF and pad have been installed, LNG tanks delivered, and the water tower rose
Booster Eclipse Port Canaveral Style

@ICommunityNote@ENNEPS@NASASpaceflight They're moving quickly, if you notice the massive technological jumps they're making. Give it time. They're doing what no one else has ever done before. 😉
A very busy day of testing at Starbase today ahead of Flight 12.
Over at the launch site, B19 underwent a potential spin prime test, before detanking. With closures in the coming days, hopefully we will see a 33 engine static fire test

No WDR? Yup - @NASA isn't planning to conduct another Wet Dress Rehearsal ahead of Artemis II, despite the TSMU LOx seals being replaced, the historical difficulties with LH2, and the work on the ICPS Helium seal.
"We've already tested the new QD in the VAB", said Shawn Quinn, Manager, Exploration Ground Systems Program.
Lori Glaze, Acting Associate Administrator, Exploration Systems Development Mission Directorate, wants the next time SLS is tanked to be a launch attempt.
I asked if this means they have definitively ruled out any Partial Tanking tests, or Integrity tests.
"At this point we have demonstrated that the seals that we have are the best seals we've ever had". "There's not more to be gained [from a Partial Tanking or Integrity Test]."

And any chance of posting vids now, from this? Asking as an old Engr Ag that'd love to see them, but now living out of state. :) Kurt, '92

@dpoddolphinpro@NASASpaceflight@NASA OMG. Can we just bring a Saturn 5 out of the museum and launch it to the Moon, please..?? I mean, how can we not know how to get to the moon after we did it six times 55 years ago...?? 🤷
They fixed the Hydrogen, just in time for Helium to start causing problems. Here's why @NASA (probably) won't launch Artemis II in March → youtu.be/dTxQMz4l5ZI
Of course, not even Starbase is immune to Valentine's Day, but at least we are edging towards the business end of prelaunch milestones for Flight 12, with engine installation on Booster 19 and rollout to Massey's for Ship 39 upcoming.

One step closer on the Stairway to Seven!
Following a successful 20 second static fire, the Alpha Flight 7 launch window will open no earlier than February 18. Stay tuned for more on the test flight. fireflyspace.com/missions/alpha…
With the conclusion of the wet dress rehearsal today, we are moving off the February launch window and targeting March for the earliest possible launch of Artemis II.
With more than three years between SLS launches, we fully anticipated encountering challenges. That is precisely why we conduct a wet dress rehearsal. These tests are designed to surface issues before flight and set up launch day with the highest probability of success.
During the test, teams worked through a liquid hydrogen leak at a core stage interface during tanking, which required pauses to warm hardware and adjust propellant flow. All core stage and interim cryogenic propulsion stage tanks were successfully filled, and teams conducted a terminal countdown to about T-5 minutes before the ground launch sequencer halted operations due to an increased leak rate. Additional factors included extended Orion closeout work, intermittent ground audio dropouts, and cold-weather impacts to some cameras, along with the successful demonstration of updated Orion closeout purge procedures to support safe crew operations.
As always, safety remains our top priority, for our astronauts, our workforce, our systems, and the public. As noted above, we will only launch when we believe we are as ready to undertake this historic mission.
This is just the beginning. It marks the start of an Artemis program that will evolve to support repeated and affordable missions to the Moon, in line with President Trump’s national space policy. Getting this mission right means returning to the Moon to stay and a future to Artemis 100 and beyond.
I want to thank the talented workforce at NASA, along with our industry and international partners, who are working tirelessly on this effort. The team will fully review the data, troubleshoot each issue encountered during WDR, make the necessary repairs, and return to testing. We expect to conduct an additional wet dress rehearsal and then target the March window.
We will continue to keep the public and the media informed as readiness progresses.
Curiosity has been working the night shift on Mars!
Using the LED lights on the end of its robotic arm, it created this rare nighttime view. It shows a small hole that the robotic geologist bored into the bedrock, revealing layers inside. Drill into the details: go.nasa.gov/49ZOmhM
As first launch from Starbase Pad 2 gets closer by the day, workers performed a test of the "FireX" system, one more in a series of tests to get the pad to be approved for operational use.

@LibertyforDacap@dpoddolphinpro@NASA Your 'hoax theories' have been busted So Many times. Out of Thousands of workers, over decades...where's 1 whistle-blower? Russia would Love to prove your hoax, but can't. Denial isn't just a river in Egypt, my friend...
We are aware of an issue impacting wireless voice and data services for some customers. Our engineers are engaged and are working to identify and solve the issue quickly. We understand how important reliable connectivity is and apologize for the inconvenience.
Final 2025 Mass-To-Orbit Numbers: @SpaceX once again dominated the game with 2,413 tonnes of known payload delivered - 1.6x their 2024 record, and 34.8x 2nd place, @ULAlaunch.
This is equivalent to ~400 male African bush elephants, or ~20 Blue whales.

*Note that payload mass is not always reported for each launch. This could be for a variety of reasons, such as national security or proprietary information concerns. For example, it is extremely likely CASC launched more mass than ULA, but they just haven't reported it.
@thepeej21@Gomo8@USCGSoutheast@USCG@USCGLANTAREA As an engineer, I hear you @Gomo8. But please take some Continuing Ed courses around Physics and Engineering before proposing that StarTrek-tech is around the corner, if only we think hard enough.
@Gomo8@USCGSoutheast@USCG@USCGLANTAREA Cost
if u want a tracking band that work at sea when you would need to spend $500+ per psssenger for the wrist band plus a registration fee with noaa or the equivalent for another country
It’s cheaper to make it harder to fall off
