Gilmour to attempt first launch again next year

According to a presentation by the CEO and founder of Australian rocket startup Gilmour Space, the company now sufficiently understands what caused the failure on its first launch attempt on July 30 to plan a second attempt in 2026.

The company is still investigating the root cause of the failure. “It looks like what went wrong on the launch is something we’ve never tested close enough to the launch conditions before,” he said, but didn’t elaborate.

One factor in the launch was the long delay between shipping the rocket to the launch site, known as the Bowen Orbital Spaceport, and the launch itself. “Rockets aren’t designed to be at the launch site for 18 months,” he said. The launch site, he noted, is just a kilometer from the ocean, creating salty conditions that can be corrosive.

That extended time at the launch site stemmed from delays securing regulatory approvals for the launch. That included not just a launch license from the Australian Space Agency but also airspace, maritime and environmental permits. “We had to get 24 different permits from the Queensland government,” Gilmour said. “All of these things take a long time to do.” He acknowledged that the company had not put enough resources into those regulatory processes. “The approval processes just took way too long.”

What is ironic is that as bad as Australia appears to be in terms of red tape, it is far better that it mother country, Great Britain. At least in Australia spaceports have been approved and at least one launch has taken place. And it only took eighteen months! In Great Britain the permitting process for its two proposed rocket spaceports has taken almost a decade, and still no vertical launches have occurred at either.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

  • Astronomers detect phosphine in nearby brown dwarf
    This is the same molecule that astronomers thought they might have maybe detected in the atmosphere of Venus. And just like then, this brown dwarf detection has been followed immediately with joyous cries “We’ve found evidence of life!” Hardly. They have found unexpected chemistry, but that is a far cry from a biosignature.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

SpaceX launches 28 Starlink satellites

SpaceX this morning successfully launched another 28 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California.

The first stage completed its second flight, landing on a drone ship in the Pacific.

The leaders in the 2025 launch race:

127 SpaceX
58 China
13 Russia
12 Rocket Lab

SpaceX still leads the rest of the world in successful launches, 127 to 98.

Distractions

Jazz
Jazz inspecting her new domain.

Posting has been relatively light this week for two reasons.

First, I am in the process of switching to a new computer, and getting it properly configured to my very complex requirements (which include a keyboard that matches the old RadioShack TRS-80 Model III) has been time consuming. Progress is being made, but with Linux there are always glitches than need fixing.

Second and more important, Diane and I adopted a new kitten this week, as shown in the picture to the right. We have named her Jazz, and getting her acclimated has required a bit of work, especially because our older cat Molly seems unhappy about the change (Nothing but hisses, which I think will fade with time). Things are improving but it does take me from work.

We hope this new family member will fill the hole when our tabby Misty disappeared in June, likely grabbed by a predator. So far it appears Jazz will do the job.

Sunspot update: For one month the Sun does what the scientists predicted!

It is the start of the month, which means it is time for my monthly sunspot update, using NOAA’s own monthly update of its graph of sunspot activity and annotating it with extra information to illustrate the larger scientific context.

This graph is below, with the green dot showing the sunspot number for activity on the Sun’s Earth-facing hemisphere in September. As you can see, the count closely matched the April 2025 prediction by NOAA’s panel of solar scientists, which posited that the Sun was finally beginning its ramp down from solar maximum (as indicated by the purple/magenta line).

Satellite propulsion startup Portal successfully tests new and radical thruster design

The satellite propulsion startup Portal has become the first commercial company to test successfully a thruster that uses concentrated sunlight to ionize a fuel.

The concept has been studied several times by NASA and other government entities, but never tested to a point where it could be used on a mission. According to this report:

For the vacuum chamber test at Portal’s Bothell lab, engineers used an electrical induction system to simulate the sun’s heating power. The apparatus reached temperatures in the range of 1,500 degrees Celsius (2,700 degrees Fahrenheit), and the performance of the thruster validated Portal’s propulsion architecture for integration with future flight hardware.

The concept is similar to an ion engine, but appears to produce more thrust, allowing it to move satellites more quickly to different orbits. Portal hopes to do an in orbitat test by next year. The company has raised $17.5 million in private funding, and $45 million from an Air Force grant.

Update on the plans to observe interstellar Comet 3I/Atlas using interplanetary spacecraft

Link here. The key take-away is that nothing is being repurposed to attempt to fly to Comet 3I/Atlas. Instead, as expected the science teams for all the Mars orbiters will turn their instruments to the comet when it is at its closest point to Mars, about 19 million miles away.

Don’t expect any Earth-shattering revelations:

The cameras on these spacecraft were designed to photograph the surface of Mars from Mars orbit, and won’t be able to pick out much detail on such a relatively small comet 30 million km away. But the cameras may be able to capture images of its long tail and also gather data that scientists can use to find out more about what 3I/ATLAS is made of.

Some spectroscopic data will be obtained, but it likely will not be much better than what Webb and other Earth-based telescopes have gotten already.

Similarly, the science team for Europe’s Juice mission, on its way to Jupiter, will take a look, but the distances and orbital positioning will likely limit what it can detect as well.
