Moon Launch Delayed Until March

The Artemis-II rocket was powered up and run through a complete countdown down to the 5-minute mark. 

The goal of the 'wet dress rehearsal' was to test every system on the rocket up to the point of igniting the engines. Fueling the rocket. Powering up and operating all the electronic systems on the rocket and Orion crew spacecraft. Communications between the ground and the spacecraft. This is routine for launches.

During the test countdown, excessive amounts of hydrogen escaped from the connection between the launch platform and the rocket. This was similar to the leaks that delayed the 2022 Artemis-1 launch.

Due to the time required to troubleshoot and fix the leak, meeting the February launch dates was not possible. 

These are the 'launch window' dates available for in March: 6, 7, 8, 9 and 11. The April launch dates would be 1, 3, 4, 5, 6, and 30.

The astronauts will spend the additional month conducting further practice in the simulators, while ground crews will perform practices as well. 

The goal of such practice is so that the crew and ground teams know instinctively all possible actions they will take during the mission to the Moon, and how to handle any emergencies.

Stay tuned.

The Moon Rocket 'Wet Dress Rehearsal"

 Geek out on this!

The Artemis II 'wet dress rehearsal' is now underway at NASA’s Kennedy Space Center in Florida.

The countdown clock began at 8:13 p.m. EST, or L-48 hours, 40 minutes before the opening of a simulated launch window at 9 pm. Mon, Feb. 2. The test is expected to go until approximately 1 a.m. Feb. 3.

The term 'wet' means they are filling the hydrogen and oxygen tanks.

This test will run the launch team, as well as supporting teams in the Mission Control Center at NASA’s Johnson Space Center in Houston and other supporting NASA centers, through a full range of operations, including loading cryogenic liquid propellant into the SLS (Space Launch System) rocket’s tanks, conducting a launch countdown, demonstrating the ability to recycle the countdown clock, and draining the tanks to practice scrub procedures. These steps ensure the team is fully prepared for launch day.

A 24/7 live stream of the rocket at the pad continues online. NASA will provide a separate feed during tanking activities, as well as real-time blog post updates regarding the test during the fueling day.

Countdown Milestones
The countdown contains “L minus” and “T minus” times. “L minus” indicates how far away we are from liftoff in hours and minutes. “T minus” time is a sequence of events that are built into the countdown. Pauses in the countdown, or “holds,” are built into the countdown to allow the launch team to target a precise launch window, and to provide a cushion of time for certain tasks and procedures without impacting the overall schedule. During planned holds in the countdown process, the countdown clock is intentionally stopped and the T- time also stops. The L- time, however, continues to advance.

During the rehearsal, the team will execute a detailed countdown sequence. They will pause at T-1 minute and 30 seconds for up to three minutes, then resume until T-33 seconds before launch and pause again. After that, they will recycle the clock back to T-10 minutes and conduct a second terminal countdown to approximately T-33 seconds before ending the sequence. This process simulates real-world conditions, including scenarios where a launch might be scrubbed due to technical or weather issues. At the end of the test, the team will drain the propellant and review all data before setting an official target launch date.

While the Artemis II crew members are not participating in the wet dress rehearsal, crew milestones occurring during launch day will be incorporated into the test timeline and the Artemis closeout crew will practice their closeout operations, which include closing the Orion crew module and launch abort system hatches.

Below are some of the key events that take place at each milestone after the countdown

Inside the terminal countdown, teams have a few options to hold the count if needed.

• The launch team can hold at 6 minutes for the duration of the launch window,
  less the 6 minutes needed to launch, without having to recycle back to 10
  minutes.
• If teams need to stop the clock between T-6 minutes and T-1 minute, 30
  seconds, they can hold for up to 3 minutes and resume the clock to launch. If
  they require more than 3 minutes of hold time, the countdown recycles back to T-
  10.
• If the clock stops after T-1 minute and 30 seconds, but before the automated
  launch sequencer takes over, then teams can recycle back to T-10 to try again,
  provided there is adequate launch window remaining.
• On launch day, after handover to the automated launch sequencer, any issue
  that would stop the countdown would lead to concluding the launch attempt for
  that day.

If all goes well, and if there's no problems with the weather or with the million elements of the rocket, then the launch may happen on February 8, 10 or 11.

Artemis to the Moon! Soon!

 America is Returning to the Moon

February may mark the moment when American astronauts return to the Moon, joined for the first time with a Canadian astronaut.

On January 17, the Artemis-II rocket was transported to the launchpad for testing and the launch. The journey from the Vehicle Assembly Building 4.2 miles to the pad took 12 hours.

If all checks out, and the weather cooperates, the giant rocket will carry Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialists Christina Koch and Jeremy Hansen. Hansen is the Canadian.

This will be a ten-day expedition to circle the Moon and return. The primary purpose is to test the spacecraft for the eventual landing on the Moon. 

It is very similar to the Christmas Eve 1968 lunar flyby of Apollo 8.

Because it will be a wider orbit than on Apollo, the crew will be the furthest from earth ever.

A 'wet dress rehearsal' has started, and will complete on February 2 with a complete countdown from filling the giant tanks with liquid hydrogen and oxygen, and then follow all countdown steps towards a launch. It will halt just before the engines fire. They will repeat that test a couple times.

This will be the most comprehensive test of all possible systems on the spacecraft, and analysis of the resulting data will determine if any issues must be fixed before launching. That will determine whether Artemis will fly this or next month. 

In February, the possible launch dates would be on Feb 8, 10 and 11. Delays from weather and problems with the million systems aboard could delay the launch to March or later, as happened with the un-crewed Artemis I in 2022. 

The March launch windows are 6,7,8,9 and 11. And should the launch be postponed into April, those dates would be the first, followed by April 2, 3, 4, 5, 6 and 30.

Stay tuned for updates on the launch date.

Congratulations to Jared Isaacman as NASA Administrator

Congratulations, Jared Isaacman for winning an overwhelming and bipartisan vote to become the new NASA Administrator.

Thank you for focusing on landing Americans back on the Moon before China can land and make a territorial claim. We must maintain a U.S. national presence in orbit, return to the Moon--this time to stay and pioneer a permanent NASA-international partner-commercial base that will be the seed for massive science, industrialization, commercialization--and tourism.

In parallel, we'll send Americans and our partners to Mars. A Mars base and eventually permanent colony will forever expand humanity's reach.

Here's a key point. Our national presence protects access for the free world and and for commercial space. We dare not let China control or deny access as they do in the South China Sea.

In your testimony to the Senate, you were absolutely correct: "This is not the time for delay but a time for action because if we fall behind — if we make a mistake — we may never catch up, and the consequences could shift the balance of power here on Earth."

As you'll know, Ye Peijian, the head of the Chinese Lunar Exploration Program declared: “The universe is like the ocean, the moon is like the Diaoyu Islands and Mars is like Huangyan Island.” Diaoyu is the CCP's name for Japan’s sovereign Senkaku Islands, and Huangyan is actually Scarborough Shoal which belongs to the Philippines. That is a poetic shot across the bow we must not ignore.

Time is short--shorter than China wishes us to believe. They have an unlimited budget, plundered technologies, and an imperative to beat us to the Moon. They could land on the Moon at early as 2017 or early 2018 if all goes well. Their propaganda timelines are spread out, yet their known progress indicates much a much sooner date.

Our pioneering exploration, continuing since Alan Shepard in 1961, enables and preserves the democratization of space, and extends to the Moon, Mars and beyond. In peace. For all mankind. Just as we promised on the plaque we left on the Moon.

Godspeed, Administrator Isaacman. Americans support a bold space program of exploration, and your efforts will inspire our youth and everyone to a greater future.

Call Senate: Confirm Jared Isaacman as NASA Administrator

Following the successful hearing in the Senate on December 3, the Senate Committee on Commerce, Science, and Transportation will hold a vote on Monday, December 8 to advance the nomination of Jared Isaacman for NASA Administrator to the Senate floor. Once approved in committee, the nomination will be sent to the full Senate for a final vote.

Take action:

• Please call the Senators who serve on the committee at 202-224-3121. LIST Ask for their vote
• Then call your own Senators in favor of confirming Isaacman in the floor vote. LIST

It's essential that NASA has an official Administrator as we prepare to send astronauts to orbit the Moon on Artemis II in February, and then Artemis III must beat China to land on the Moon, ideally in late 2027 or early 2028.

You may hear "China will land in 2030, etc. That's deceptive tactics to make us believe there's no hurry. The truth is the Chinese have an unlimited budget, a militaristic drive to beat us and make territorial claims as in the South China Sea, and their progress in building and testing the hardware is advancing rapidly.

Mr. Isaacman understands the imperative. In his testimony, he stated:

I know it is not lost on anyone in this room that we are in a great competition with a rival [China] that has the will and means to challenge American exceptionalism across multiple domains, including in the high ground of space. This is not the time for delay, but for action, because if we fall behind--if we make a mistake--we may never catch up, and the consequences could shift the balance of power here on Earth.

Let's get Isaacman on the job and go full speed back to the Moon and on to Mars.

Apollo 11 56th Anniversary! Mission Day One

Imagine this: It is July 16, 1969, and hundreds of thousands of people camped out near the Kennedy Space Center overnight waiting for the launch of Apollo 11. 

Hundreds of millions more around the world are glued to their TVs and radios, awaiting the magical moment. It's a bright sunny morning and Apollo 11 is gleaming on the launch pad as technicians check the million-plus systems that all must work perfectly.

Neil Armstrong, Buzz Aldrin and Michael Collins wave to the cameras as they depart for the pad, and ascend 365 feet to the top of the Saturn V rocket. The hatch is closed, technicians continue their checks of the million or so components that all must work perfectly, and the world awaits...

All systems are GO!

The time is 9:32 AM. The world holds its breath!

10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0! Smoke and fire billow from the mighty engines and slowly the rocket rises, then faster and faster. Humanity cheers on the launch of Apollo 11 on its historic mission to land Americans on the moon.

Apollo 11 is now in orbit. Two hours and 44 minutes later, the engines fire to take the spacecraft out of earth orbit and towards the moon, still a quarter of a million miles distant.

The adventure begins.

Don’t Skip the Moon!

The National Imperative to Secure Free World and Commercial Access to the Moon

A presentation at the 2025 International Space Development Conference.

The Coalition to Save Manned Space Exploration
June 19, 2025

There’s increasing excitement at the prospects of returning to the Moon and going to Mars. No longer perpetually a decade away, but much sooner. Elon Musk wants to send a fleet of Starships to Mars in November of next year, and crew at the next window in 2029. The ‘Human Landing System’ version of Starship is being designed to land crew on the Moon as well as massive amounts of cargo.

Immediately, though, we need a NASA Administrator to be selected and confirmed by the Senate, followed by rapid decision-making. The future direction of NASA is unknown, and we’ll have to wait for answers once a nominee is announced. Acting Administrator Janet Petro remains in charge, but in that role, she can only preside over existing programs.

The NASA Administrator must be prepared to bust the bureaucracy and accelerate crewed Lunar and Martian exploration plans, and must have a deep understanding of our space program.

The status of proposed budget cuts, cancelled projects and science, and plans for Artemis beyond Artemis-III remains unknown until a new administrator offers such clarity and works with Congress to reach a defined path for the next several years.

We urge NASA to not abandon the Moon after Artemis III, but to build a permanent NASA and commercial presence on the Moon, along with our international partners.

Partnering with many of our ISS partners on the Moon will accelerate the timeline and result in greater soft power, cultural diplomacy and most immediately of concern, help restrain China.

Starship has many steps to being ready for both Lunar and Martian missions. These include:

·     Repeated successful launches and landings.

·     Orbital flights.

·     Building and testing the entire refueling infrastructure.

·     Uncrewed Lunar landings and returns.

·     And when used beyond Artemis’ SLS/Orion-based crew launches, Starship will require human-ratings for both launch and reentry.

These are steep milestones for SpaceX, and we do not have much time to make it all work to prevent a Chinese declaration of sovereignty.

A “Plan B” may be necessary as well.

As an insurance policy against delays in SLS/Orion and Starship HLS, the next administrator could consider the use of dual Falcon and Falcon-Heavy launches using the Blue Moon lander—similar to China’s LM-10 mission profile. Note that the Crew Dragon heatshield is not designed for Lunar return velocities, and it is unknown if a heatshield could be designed and tested in time. Perhaps Orion could be launched on a Falcon Heavy or Blue Origin’s New Glenn.

As a national priority, Artemis must be accelerated. At least ready Artemis-II for launch late this year. And Artemis-III’s SLS and Orion should be readied for late next year or early 2027, in case Starship HLS or Blue Moon are ready by then.

We will return to the Moon and go to Mars. But we must not plant the flag and forget it for another half century. For the sake of the free world and commercial space, our absence would invite China to make their long-promised territorial claim.

That would mean that the incredible prospects for multi-billion dollar industries, helium-3 mining, scientific labs, far-side telescopes, and of course tourist centers would never happen. By the free world, that is.

The threat from China was best illustrated with the 2017 poetic threat by Ye Pei-Jian, the head of China’s military-led Lunar Exploration Program.

“The universe is the ocean: the moon is the Diaoyu Islands and Mars is Huangyan Island.”

Those are China’s names for the islands in the East and South China Seas that China seized and militarized in violation of the 400 years of freedom of the seas and the Law of the Sea Treaty, as well as preparing for wars of conquest. He gave a clear warning of their goal to similarly dominate outer space.

This is a declaration of intention, just as is China's ‘nine-dashed line,' which they use to illegally declare sovereignty in the South China Sea and over the territories of other countries.

We would be wise to deter China’s worst instincts by safely accelerating our lunar plans. Returning to the Moon to beat China must be the national imperative for our Artemis program.

We must construct and maintain, with commercial and international partners, a permanent lunar base. China’s military-led space program is designing theirs. We must do no less.  

When could China land crew on the Moon? Here are some clues to their timing.

·     Partial and full static fires of Long March-10. A partial static fire involving three engines has been performed with LM-10. The LM-10 is their “Falcon-Heavy” equivalent. Two would be used for a lunar mission. One launch with the crew capsule, and another with the lander to rendezvous with the crew capsule.

·     The first test launch of LM-10.

·     Photographs and public displays of stages or stacked LM-10 rockets, the lander and other hardware.

·     The first full-up test mission of LM-10. This may be only an orbital test or it could be an uncrewed flight to the Moon similar to Artemis I, where they could practice rendezvousing and docking with the lunar lander.

·     If successful, their second mission may copy Artemis-II using the two LM-10 systems on a crewed orbit of the Moon as well as performing an Apollo-10-like docking with their lander.

With successful test launches of LM-10, expect a rapid cadence of launches, with months, not a year or more between crewed lunar missions, and preparations to establish their permanent lunar base.

China has already flight-tested their new crew capsule. Those milestones are the first clues for their timeframe to land crew on the Moon.

The third launch of the LM-10 rockets may copy Artemis-3 with a crewed landing. Assuming successes, their cadence of launches will be much faster than for Artemis.

Note that China employs deception to keep us slumbering. China won’t go to the moon in 2030. Expect more like 2027. Or even sooner if their uncrewed and first crewed mission succeeds. China has an unlimited budget and an imperative to beat the US to the Moon.

Eventually, China’s LM-9, a reusable Starship knockoff, will be used for lunar and Martian missions.

Prioritizing a continuing U.S.-led free world presence on the Moon will forestall a Chinese territorial claim, and lessons learned on the Moon will make Martian missions and colonies safer and more successful.
