Russia completes 1st test, suborbital, of its new Soyuz-5 rocket

According to Russia’s state-run press, it successfully completed the first suborbital test flight of its new Soyuz-5 rocket, the rocket lifting off from Baikonur in Kazahkstan on April 28, 2026 carrying a dummy payload.

A special launch was conducted today as Soyuz-5, a new Russian carrier rocket with the world’s most powerful liquid-fuel engine, blasted off. <...> Operating the rocket will make it possible to substantially reduce the unit cost of the payload capacity. This will have a positive impact on the economics of space launches,” the Russian state-owned space corporation quoted its CEO Dmitry Bakanov as saying.

The rocket will eventually be able to place about 17 tons in low Earth orbit, making it more powerful than the Soyuz-2 — now used to launch capsules and satellites — but less powerful than Russia’s Proton rocket, used to launch station modules and other more demanding missions.

Soyuz-5 however is not reusable, so it will remain more expensive to use that the new rockets being developed everywhere else outside Russia. Like all of Russia’s rockets, stages will continue to fall inside Russia with each launch. In this case, the first stage and fairings crashed somewhere in Russia, while the second stage splashed down in the Pacific.

Ireland to sign Artemis Accords

According to a NASA press release late yesterday, Ireland will sign the Artemis Accords on May 4, 2026, becoming the 65th nation to join this American space alliance.

NASA Administrator Jared Isaacman will host Ambassador of Ireland to the United States of America Geraldine Byrne Nason; Minister for Enterprise, Tourism and Employment Peter Burke, T.D., of Ireland; and U.S. Department of State officials for the ceremony.

As I predicted yestesday when Morocco signed the accords, the success of the Artemis-2 mission around the Moon has prompted a number of smaller third world countries to finally sign the accords, and thus should expect more signings to follow. Ireland illustrates this. There will be more soon.

The full list of nations in this American space alliance is as follows:

Angola, Argentina, Armenia, Australia, Austria, Bahrain, Bangladesh, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Cyprus, Czech Republic, Denmark, Dominican Republic, Ecuador, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Ireland, Israel, Italy, Japan, Jordan, Latvia, Liechtenstein, Lithuania, Luxembourg, Malaysia, Mexico, Morocco, the Netherlands, New Zealand, Nigeria, Norway, Oman, Panama, Peru, Poland, Portugal, Romania, Rwanda, Saudi Arabia, Senegal, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Thailand, the Philippines, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

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.

The present state of India’s space program

India's Bharatiya Antariksh Station as outlined in 2024

India’s space agency ISRO yesterday released its annual report [pdf], outlining its accomplishments over during 2025.

Like all such reports, it is filled with glowing superlatives. It provides little concrete information about the agency’s more serious issues, such as what it is doing to fix the upper stage of its PSLV rocket, which has failed on the last two consecutive launches. All the annual report says on this subject is the following:

Based on the recommendations of the National Level Committee comprising of eminent experts from academia & industry, the third stage of PSLV i.e., HPS3 motor with modified design was realised and two static tests were successfully completed on October 06, 2025 and November 19, 2025 as in flight, from SDSC, SHAR. The overall performance of the motor and subsystems were as expected and closer to nominal performance.

The problem is that these fixes and tests did not work. The second failure of the upper stage occurred in January 2026, less than two months later. The annual report should have noted this fact, but did not.

As for India’s planetary program, digging out the present schedule from the report is difficult. Based on this review of the annual report, the dates are as follows:

  • Chandrayaan 4 lunar sample return mission: October 2027.
  • Venus Orbiter: March 2028.
  • Chandrayaan 5 /LUPEX lunar lander: September 2028.
  • Mars Lander: No target launch date as yet.

Expect these dates to be delayed.

The report also gives a detailed description on India’s Gaganyaan manned program, but little information about the planned unmanned tests that were planned for this year, leading to a manned orbital mission next year. At the moment the schedule appears to be experiencing delays, caused mostly by the PSLV launch failures. It appears ISRO wants this issue resolved before it launches that first unmanned Gaganyaan test flight.

If you want to get an overview of India’s government space program, this annual report is a good place to start. It will at least provide a baseline on which you can build a deeper knowledge.

Falcon 9 upper stage to hit the Moon in August

Falcon 9 impact on Moon in August
Click for original image.

According to astronomer Bill Gray, who also tracks orbital objects, the upper stage of the Falcon 9 that launched Firefly’s Blue Ghost and Ispace’s Hakuto-R2 lunar landers in January 2025 will hit the Moon on August 5, 2026.

For some time, I’ve provided some software tools astronomers can use to identify satellites in their data. I use the US military’s publicly available satellite data for many objects, and compute orbits for high-orbiting objects the military doesn’t track.

This object falls squarely in the latter category. In September 2025, my software for computing orbits analyzed the observations and projected an impact with the moon on 2026 August 5.

While this looked like a pretty solid prediction, I couldn’t be totally sure of it at the time. The motion of space junk is mostly quite predictable; it simply moves under the influence of the gravity of the earth, moon, sun, and planets. We know those with immense precision. If those were the only factors involved, I could probably tell you where and when this object would hit the moon to within a few meters and a fraction of a second.

The problem is that space junk in general, and 2025-010D in particular [the upper stage], is also pushed around by sunlight (“solar radiation pressure”). This is an extremely gentle force, but over months, it can really build up. And it’s not entirely predictable. As an object tumbles, it may catch more or less sunlight, and may reflect some of it sideways. So sunlight is mostly pushing the object away from the sun, but there’s a slight bit of pushing in other directions as well.

With enough data, we can actually figure out where the forces are pushing an object. But they do change a little over time in ways that aren’t perfectly predictable. So I can be sure it will impact near the time and place I’ve predicted, but those varying forces mean that the actual impact will be at least a little off from that time and place. That’s the largest source of uncertainty in all this, and there’s no way to correct for it; we just have to wait and see what actually happens. (But come August, we’ll have a quite precise idea of where it will hit.

At present, Gray predicts the impact will occur at 2:44 am (Eastern) on August 5, 2026. The image above is his present estimate of where it will hit, as seen from Earth. If this prediction holds, the impact itself will likely not be visible from Earth, as it will occur in daylight and at the very western limb of the Moon. This prediction however could change somewhat in the next few months.

When it hits Gray estimates the stage will be moving at about 5,400 miles per hour, or 1.51 miles per second. Expect the science team for Lunar Reconnaissance Orbiter (LRO) to try to image this impact after the fact.

Morocco signs the Artemis Accords

The State Department yesterday announced that Morocco has become the 64th nation to sign the Artemis Accords.

Moroccan Foreign Minister Nasser Bourita signed the Accords on behalf of the Kingdom of Morocco on April 29 at a ceremony in Rabat, Morocco. U.S. Deputy Secretary of State Christopher Landau and U.S. Ambassador to Morocco Duke Buchan III witnessed the signing.

It does appear that the success of the Artemis-2 mission around the Moon has prompted a number of smaller third world countries to finally sign the accords. Before the mission there had been a slow-down in new signatories. In only the past two weeks however Latvia, Jordan, and now Morocco have joined. We should expect more in the coming months, because they all want to get in on the game, while the getting is good.

The full list of nations in this American space alliance is as follows:

Angola, Argentina, Armenia, Australia, Austria, Bahrain, Bangladesh, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Cyprus, Czech Republic, Denmark, Dominican Republic, Ecuador, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Israel, Italy, Japan, Jordan, Latvia, Liechtenstein, Lithuania, Luxembourg, Malaysia, Mexico, Morocco, the Netherlands, New Zealand, Nigeria, Norway, Oman, Panama, Peru, Poland, Portugal, Romania, Rwanda, Saudi Arabia, Senegal, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Thailand, the Philippines, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

Two launches yesterday

Both SpaceX and Arianespace successfully completed orbital launches yesterday. First, SpaceX placed another 24 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California. The first stage completed its 13th flight, landing on a drone ship in the Pacific.

Next, Arianespace placed 32 more Amazon Leo satellites in orbit, its Ariane-6 rocket lifting off from France’s French Guiana spaceport in South America. The expendable Ariane-6 launched for the second time in its most powerful configuration, with four side boosters. This was also Arianespace’s second launch this year, so it remains off the leader board below. It is also the second launch in Arianespace’s 18-launch contract with Amazon to launch Leo satellites. The satellites were placed at an orbit of 465 kilometers, which SpaceX has claimed violates its Starlink orbital territory. Amazon has agreed what it is doing is a violation, but says it will continue to do so for this and two more launches.

With this launch, Amazon now has 302 Leo satellites in orbit, out of the 1,616 it needs to launch by July to meet its FCC license requirement. The company’s request for a time extension is presently pending at the FCC.

The leaders in the 2026 launch race:

52 SpaceX
23 China
8 Russia
6 Rocket Lab

For the third straight year SpaceX continues to lead the entire world combined in total launches, 52 to 44.

Russia was also supposed to do a test suborbital launch of its new Soyuz-5 rocket. As of posting I have not been able to confirm whether the launch took place.

Who really was Jay Gould?

The life and legend of Jay Gould

To get to the point, right at the start, Jay Gould was not a “Robber Baron”, nor was he the worst “Robber Baron,” as many journalists of his time as well as many historians in the next century liked to slander him, implying he was unethical, cruel, and routinely used under-handed tactics to destroy others while making himself wealthy. In fact, he was no more a robber baron then the entire class of hard-nosed businessmen who in the 1800s became America’s first generation of today’s billionaires, using the free enterprise system to gather wealth to themselves while building vast industries that employed millions and made the lives of everyone better and more prosperous.

I have just finished reading Maury Klein’s 1997 fine biography of Jay Gould, the Life and Legend of Jay Gould, and was not surprised to learn that Gould was never the evil personification of worst sort of capitalist, as routinely portrayed by our leftist academia for the past century. Instead, I discovered he was no different then all the other leading businessmen of his time, hard-nosed and ruthless when it came to cutting deals, but strongly committed to making the businesses he ran profitable and successful, providing the public a useful product they would be eager to use.

You see, in a free capitalist society, you can’t succeed unless you are willing to be ruthless at times. This doesn’t necessarily mean you routinely use violence, or break the law, or go out of your way to hurt others, but it does mean you defend yourself from attack, and retaliate quickly using legal means when under attack. These rules apply today as they did in Gould’s time. Nothing has changed.

Gould was no different than Cornelius Vanderbilt (whose life I reviewed here). Nor does he differ from John D. Rockefeller, or Elon Musk, or Jeff Bezos, or any one of the thousands and thousands of American businessmen, who from the founding of this country used its free but legal framework to build a nation while enriching themselves.

Gould’s most famous area of success involved his ownership of many railroads, both in the American west as well as the first elevated subways in New York City. He also gained full control over Western Union, and for more than a decade ran a system that provided the entire country and even the world its first instantaneous method of communications. To gain control over these venues involved many battles, some of which required tactics that were harsh, even a bit under-handed, and clever. Sometimes it required payoffs to politicians, or tricky stock deals that once completed left many others sinking in the wake.

Gould’s tactics however were never much different than those of others of his ilk. And like those others, his overall good management of his companies he controlled, as well as the good treatment of the people who worked under him, garnered strong loyalty and support across these industries. Gould wanted control, but always when he had it he used it to make his product better and more useful.

When he died, it was the people who knew him who had good things to say about him, and it was the journalists who did not who continued to spread the slanders, because it made good copy and sold newspapers. And sadly, for the decades that followed, historians used those news reports — mostly wrong — as their primary sources of information, and thus the legend of an evil Gould was created.

Klein’s biography is a worthy effort to counter this bad history. More Americans should read it, if only to realize their past history was far more admirable than what they have been taught for the past few generations.

Gould’s tactics — and his success — were things he learned very earlier on in life, when he went out on his own.
