Indian rocket startup Skyroot hires Exolaunch to handle satellite integration and deployment

8:03 am

The Indian rocket startup Skyroot yesterday signed a partnership agreement with the company Exolaunch to handle the integration and deployment of satellites once its Vikram smallsat rocket begins launching.

Through this agreement, Exolaunch will integrate and deploy customer satellites on Skyroot’s Vikram series of launch vehicles, beginning with the Vikram-1 orbital missions. Exolaunch will provide its flight-proven deployment technologies for Skyroot customers across dedicated and rideshare launches. The partnership also includes the use of Exolaunch’s EXOtube payload stacks, designed to optimize multi-payload rideshare configurations, streamline constellation launches, increase mission flexibility, and enhance vehicle utilization.

While Skyroot has not yet launched, Exolaunch is very well established, having “a decade of flight heritage and 582 satellites launched across 39 missions to date.” Since Skyroot has no experience yet in these matters, having Exolaunch do it makes satellite companies more likely to buy space on its rocket.

Until recently Skyroot had been targeting a first launch before the end of this year. That schedule has now changed. According to the company’s webpage, that first launch is now scheduled sometime in 2026.

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.

Peeling brain terrain in Martian crater

12:16 pm

Overview map

Peeling brain terrain on Mars
Click for original image.

Today’s cool image takes us once again back to Mars’ glacier country, the 2,000 mile-long mid-latitude strip in the northern hemisphere where almost every image shows glacier features. The picture to the right, cropped, reduced, and sharpened to post here, was taken on September 4, 2025 by the high resolution camera on Mars Reconnaissance Orbiter. It shows a small section of the floor of an unnamed 13-mile-wide crater, highlighting what the science team labels vaguely as “features.”

Those features appear to be glacial debris whose surface alternates between peeling gaps and the unique Martian geology dubbed “brain terrain”, whose formation is not yet understood but is believed to be associated with near surface ice.

The location is indicated by the white rectangle on the overview map above. At 36 degrees north latitude, this crater is deep within that mid-latitude strip where a lot of glacial features are routinely found. If you look at the inset, you can see that all the nearby craters appear to have formed in what appears to be slushy ground, their rims not very pronounced or distorted and their floors shallow, as if the ground melted like ice upon impact but very quickly solidified.

Mars is not a dry place. Future colonists will likely build their first cities around 30 degrees latitude, close enough to the equator to get warmer temperatures, but close enough to the near-surface ice found just a few degrees poleward, in a place such as this.

New Morgan Stanley report reflects Wall Street’s generally optimistic view of Rocket Lab

8:56 am

Rocket Lab's stock in 2025
Click for source.

Though Rocket Lab is still not in the black, a new positive analysis of the company this week from Morgan Stanley reflects Wall Street’s generally optimistic view of Rocket Lab during the past year.

Rocket Lab (NASDAQ:RKLB) had its price target raised by equities researchers at Morgan Stanley from $20.00 to $68.00 in a research report issued on Monday, Benzinga reports. The brokerage presently has an “equal weight” rating on the rocket manufacturer’s stock. Morgan Stanley’s price target would suggest a potential upside of 1.63% from the company’s current price.

The article at the link also notes that Morgan Stanley is not alone in giving Rocket Lab a positive report, and in fact in the past year it shows that the recommendations from many analysts to buy its stock have risen considerably. These positive reviews have been reflected in a steady rise in the company’s stock price in 2025, as shown by the graph on the right.

Nor are these reports written in a vacuum. In recent weeks Rocket Lab has signed a bunch of new launch contracts, some extending deals with old customers, some with new customers of some note.

Buying the stock of a startup like Rocket Lab always carries risk, but it appears Wall Street is beginning to see the future of this particular startup as very promising.

Orbital tug startup Impulse Space to develop its own unmanned lunar lander

8:25 am

Impulse's tug and proposed lunar lander
Click for original image.

The orbital tug startup Impulse Space, founded by Tom Mueller (one of SpaceX’s first engineers), is now proposing to build its own unmanned lunar lander, with a target for delivering six tons of cargo on two missions, starting in 2028.

Our proposed architecture combines our existing Helios kick stage and a new lunar lander, to be developed by our team in-house. Helios would launch on a standard medium- or heavy-lift rocket. Our lunar lander would ride as a payload on Helios. Once Helios and the lander are deployed in Low Earth Orbit (LEO), Helios serves as a cruise stage, transporting the lander to low lunar orbit within one week. The lunar lander then separates from Helios and descends to the surface of the Moon. By taking advantage of Helios’s high delta-v capabilities, this mission architecture doesn’t require in-space refueling.

This solution can bridge the existing cargo delivery gap by offering direct transportation of the necessary mass to kickstart infrastructure, resource utilization, and economic activities on the Moon. We’ve already begun engine development for our lunar lander solution, and we stand ready to execute as dictated by industry demand and interest.

With this Helios and Impulse-made lander combination, we estimate delivering up to 6 tons of payload mass to the Moon (across two missions) per year starting in 2028 at a cost-effective price point. Each Helios + lander combo would take approximately 3 tons of cargo to the Moon.

It appears the company has identified a need (transporting cargo to the Moon cheaply and quickly) that no one (including NASA) is presently considering. SpaceX will be able to do it with Starship. Blue Origin is also proposing to do it with various versions of its Blue Moon manned lander. Impulse has decided however that both of those spacecraft are too large and tied to SLS and Lunar Gateway, with Starship requiring refueling, that makes their cargo missions more costly than a direct mission. Impulse proposes a simpler option.

This decision is also another indication that the demand for low orbital tugs is not developing as expected. It appears satellite companies and the available rocket companies have worked out ways to get most of their satellites to the orbits they require without tugs.

It will be interesting to watch if this proposal gains traction. If it does, than it will likely encourage other orbital tug as well as the other lunar lander companies to propose their own alternatives.

Space Force approves Vandenberg environmental assessment, allowing SpaceX’s to launch as much as 100 times annually

8:02 am

Map of Vandenberg Space Force Base, showing SpaceX's two launchpads
Figure 2.1-1 of the final environmental assessment report

The Space Force on October 10, 2025 announced it has now finalized and approved the environmental assessment that will permit SpaceX’s to increase its launch rate at Vandenberg to as much as 100 times per year.

The DAF [Air Force] has decided to increase the annual Falcon launch cadence at VSFB [Vandenberg] through launch and landing operations at SLC-4 and SLC-6 [the two SpaceX launchpads], including modification of SLC-6 for Falcon 9 and Falcon Heavy launch vehicles to support future U.S. Government and commercial launch service needs. The overall launch cadence will increase from 50 Falcon 9 launches per year at SLC-4 to up to 100 launches per year for Falcon 9 and Falcon Heavy at both SLCs combined. Falcon Heavy, which has not previously launched from VSFB, would launch and land up to five times per year from and at SLC-6. The DAF will authorize SpaceX to construct a new hangar south of the HIF [SpaceX’s horizontal integration facility] and north of SLC-6 to support Falcon 9 and Falcon Heavy integration and processing.

You can read the full environmental assessment here [pdf]. The map to the right, from the assessment, shows the location at Vandenberg of the two SpaceX launch sites. SLC-4 (pronounced “slick-four”) is the pad SpaceX has been using for years to launch Falcon 9s. SLC-6 was originally built for the space shuttle but never used for that purpose. Subsequently ULA leased it to launch its Delta family of rockets. When that rocket was retired SpaceX won the lease to reconfigure the site for both Falcon 9 and Falcon Heavy launches.

The Space Force apparently decided to ignore the objections of the California Coastal Commission as well as a number of anti-Musk leftwing activist groups. And its decision is well grounded in facts. The report documents at length the lack of any consequential environmental impacts from the increase of launches, which is further supported by almost three quarters of a century of actual use.

The decision is also well founded in basic American culture and law. The Space Force as a government agency must act as a servant of the American people, in this case represented by the private company SpaceX. It must therefore do whatever it can to aid and support that company, not put up roadblocks because it doesn’t like what the company proposes.

At least under Trump, this is the approach the Space Force is taking. I fear what will happen if a Democrat regains the presidency, based on the radical and enthused communist make-up of that party today.

The hurricane season in 2024 confounded the predictions again

1:04 pm

The trail of bad global warming predictions

The uncertainty of science: Though the climate science community had predicted that last year’s hurricane season was going to be one of the most active ever, a new study published two weeks ago in Geophysical Research Letters of the American Geophysical Union (AGU) found that the 2024 season did not behave as predicted. It ended up producing about the predicted number of hurricanes, but did so only because of a sudden rise in activity near the end of the season, after a long lull with almost no activity. From the study’s conclusion:

As has been noted throughout this study, the lull was immediately followed by one of the busiest ends to an Atlantic hurricane season on record, including two major hurricane landfalls in Florida (Helene and Milton), resulting in more than 250 fatalities and $100 billion in damage (National Centers for Environmental Information, 2025). Though the final overall number of hurricanes and major hurricanes were aligned with the seasonal forecasts, the extremely busy beginning and end to the season and marked lull in the middle highlight just how unusual the season was.

Last year’s prediction was not the first to be incorrect, though this time the error was in how the season unfolded instead of the total numbers. In the past two decades — since Al Gore prophesied that global warming would cause a gigantic increase in violent storms — NOAA has repeatedly called for very active hurricane seasons, and repeatedly those predictions have turned out wrong. In fact, from 2006 until 2018 there were almost no major hurricanes at all, the exact opposite to what Gore had foretold. Since then the seasons have returned to more normal numbers, but the predictions of the scientists have continued to be no better than throwing a dart at a wall while wearing a blindfold.

The ongoing 2025 hurricane season is following this same pattern. In May 2025 NOAA predicted this year would be a very active hurricane season. Instead, this season has matched those from 2006 to 2016, in which no hurricanes made landfall in the U.S. and the number of strong hurricanes was almost nil.

The season of course is not yet over. We could see a burst of activity in the next few months, similar to what happened in 2024. Nonetheless, the important takeaway from this story is that the scientists who claim to know what is going to happen simply don’t know anything. They are guessing, because as the paper above admits, the Earth’s weather and climate are incredibly complex, and our understanding of it is still in its infancy.

Remember this when you read the next “We’re all gonna die!” prediction touted in the propaganda press.

Three launches in the past day

9:45 am

Even as all eyes focused on SpaceX’s 11th test launch of Starship/Superheavy yesterday, there were three other launches in the past fourteen hours taking place on three different continents by China and two different American companies.

First, China placed a technology test satellite into orbit, its Long March 2D rocket lifting off from its Jiuquan spaceport in northwest China. The only information about the satellite is that it will test “new optical imaging.” No information at all was released on where the rocket’s lower stages, using very toxic hypergolic fuels, crashed inside China.

Next, SpaceX placed 24 of Amazon’s Kuiper satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida. The first stage completed its second flight, landing on a drone ship in the Atlantic.

With this launch, Amazon now has 154 satellites in orbit, out of a planned constellation of about 3,200. Its FCC license requires it to have about 1,600 in orbit by July of ’26, but that goal seems increasingly unlikely to be met. With this launch SpaceX completed its three-launch contract for Amazon. It has contracts with ULA for 46 launches (having so far completed three in 2025), and that company appears ready to launch regularly in the coming months. Amazon’s other launch contracts with Blue Origin’s New Glenn (27 launches) and ArianeGroup’s Ariane-6 (18 launches) however are more uncertain. Neither company has achieved any launches on their contracts, and it is not clear when either company, especially Blue Origin, will ever begin regular launches.

Finally, this morning Rocket Lab placed the seventh radar satellite into orbit for the company Synspective, its Electron rocket lifting off from one of its two launchpads in New Zealand. Rocket Lab has a contract for another twenty Synspective launches over the next few years. The launch also featured a larger fairing that will give the company the ability to launch bigger-sized satellites with Electron.

The leaders in the 2025 launch race, now including yesterday’s Starship/Superheavy launch:

131 SpaceX
60 China
13 Russia
13 Rocket Lab

SpaceX now leads the rest of the world in successful launches, 131 to 101.
