Who was Cornelius Vanderbilt?

The First Tycoon

I ask the question in my headline because I am quite sure it is a question most Americans can no longer answer, with any firm knowledge. I myself didn’t know who Vanderbilt really was until I read a wonderful biography of him, The First Tycoon: The epic life of Cornelius Vanderbilt by T.J. Stiles, about two months ago.

Beforehand, all I really knew about Vanderbilt was that he had been a big deal somehow in the 1800s, and as a result there was a statue of him on the south side of Grand Central Station in New York, visible only by drivers going past on the overpass that circles the station.

What I learned from Stiles book however was astonishing. Not only did Vanderbilt build Grand Central Station, it was part of a transportation empire he created that by the end of his life covered most of the eastern United States. For Americans in the 1800s, if you needed to get from one place to another, you almost certainly rode on a Vanderbilt steamship or railroad.

Even more interesting to me however were the remarkable similarities in style, approach, and success between the Cornelius Vanderbilt of the 1800s and the Elon Musk of the 2000s. Both focused on taking new technology and making it profitable. Both built their empires on transportation.

And most of all, both focused on the product they were building to make money, not on speculating its value to make a quick buck.

Two Middle Eastern startups sign deal to build a mini-shuttle dubbed Oryx

A rocket startup in the UAE, Aspire, has signed a partnership deal with a rocket engine startup in Dubai, Leap71, to build a fully reusable mini-shuttle dubbed Oryx, not unlike the Dream Chaser mini-shuttle that Sierra Space has been trying to launch now for more than a decade.

As part of the plan, Leap71 will develop two types of engines for Oryx, including one using an aerospike nozzle.

Building on their ongoing cooperation, Aspire Space is now contracting LEAP 71 to develop the rocket engines powering the Oryx’s second stage. Each engine will produce 20 tons (200 kN) of thrust, and the partners are pursuing two parallel propulsion paths: a conventional engine and a novel aerospike configuration.

The aerospike concept, long studied but never flown, offers superior efficiency across both atmospheric and vacuum flight regimes — making it particularly well suited for reusable launch systems. LEAP 71 gained international recognition in December 2024 for successfully testing a 5 kN aerospike engine, validating key aspects of its design.

The picture to the right shows the LEAP aerospike engine during those 2024 tests. As I noted then, “The spike in the center acts as one wall of the nozzle, and the changing pressure of the atmosphere acting as the other side of the nozzle, allowing the nozzle size to change as the rocket rises, thus making its thrust as efficient as possible.”

Those tests were done in the United Kingdom, suggesting the company relied on British engineers using financing from Dubai. Even so, to go from that smallscale test to a full engine launching both a rocket and a reusable mini-shuttle will be a major challenge. Or to put it another way, to say their plans are aspirational is an understatement.

A magnificent barred spiral

A barred spiral
Click for original image.

Cool image time! The picture to the right, reduced to post here, was released two weeks ago as the European Space Agency’s (ESA) Hubble picture of the week, showing a classic barred spiral galaxy that is estimated to be about 50 million light years away. From the caption:

This galaxy has been nicknamed the ‘Lost Galaxy’ because it’s extremely faint when viewed through a small telescope.

…On full display in this Hubble image are NGC 4535’s young star clusters, which dot the galaxy’s spiral arms. Many of the groupings of bright blue stars are enclosed by glowing pink clouds. These clouds, called H II (‘H-two’) regions, are a sign that the galaxy is home to especially young, hot, and massive stars that are blazing with high-energy radiation. By heating the clouds in which they were born, shooting out powerful stellar winds, and eventually exploding as supernovae, massive stars certainly shake up their surroundings.

The photo was taken as part of a survey of similar nearby galaxies in order to study these H-II regions.

I look at that bar and wonder at the wondrous mystery of the universe, to form such shapes.

It is so far a very slow news day.

A company that wants to shoot payloads into orbit with a cannon

Link here. The company is called Longshot. It isn’t the only company attempting to do this. I reported on another company, Green Launch, in 2022, but have heard little from it since then.

I leave it to the engineers in my readership to tell me if this company has any chance of success. It seems to me that any payloads it launches would likely have to be dead weight, like water or oxygen or fuel, as the speeds involve would damage delicate instrumentation.

SpaceX launches 28 Starlink satellites; 1st stage flies for first time

UPDATE: When I wrote this post, several sources stated that the first stage was flying for its thirtieth time. I relied on those sources. As it turns out, they were wrong. The first stage on this launch was flying for its first time. The post below has been rewritten to correct this error.

———————–
SpaceX early this morning successfully placed another 28 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California.

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

The leaders in the 2025 launch race:

154 SpaceX (a new record)
72 China
15 Rocket Lab
13 Russia

SpaceX now leads the rest of the world in successful launches, 154 to 120.

Startup B2Space launches rocket from balloon

The startup B2Space has completed a test flight using a balloon to lift a solid-fueled rocket to high altitude, where the rocket was then launched.

In a 17 November update, the company announced that it had completed a test of its integrated rockoon launch system using a “rocket of lower power than that planned for the commercial version of the system.” The test was conducted from the Port of Vueltas in Valle Gran Rey in the Canary Islands. Its aim was to validate key elements of the company’s rockoon launch system, including the rocket rail alignment and ignition subsystems.

The balloon was launched at 4:00 CET and carried the small rocket to an altitude of 21.5 kilometres, at which point the rocket was launched. Speaking to European Spaceflight, B2Space CTO Valentin confirmed that the ignition system had been successful but did not share any details about the state of the rocket itself. In a 17 November update, the company confirmed that all elements of the launch system had been successfully recovered following the test.

Calling this company a startup is not quite accurate, as it has been around for almost a decade, pushing the idea of a a balloon-launched rocket, dubbed a “rockoon”. The idea itself is not new. If my memory serves me right, it had been tested intermittently in some form as early as the 1950s.

The company hopes to test a larger suborbital version in 2026, followed by an orbital test.

SpaceX issues 1st statement regarding Superheavy test explosion

Damaged Superheavy
Click for original image.

SpaceX yesterday issued its first update regarding the explosion in the lower half of the Superheavy booster that it had planned to fly on the next orbital test flight.

Booster 18 suffered an anomaly during gas system pressure testing that we were conducting in advance of structural proof testing. No propellant was on the vehicle, and engines were not yet installed. The teams need time to investigate before we are confident of the cause. No one was injured as we maintain a safe distance for personnel during this type of testing. The site remains clear and we are working plans to safely reenter the site.

That no propellant was involved explains why the booster and test pad experienced relatively little damage. They were likely pumping nitrogen through the system to test it, and while something exploded, the gases were not volatile.

The picture to the right is a screen capture from aerial drone flights performed by RGV Aerial Photography and posted on nasaspaceflight.com. I have enhanced it to bring out the details. Note the lack of damage on all sides of the booster at its base. The explosion was clearly confined to the booster, and appears to have occurred from within.

November 21, 2025 Quick space links

Courtesy of BtB’s stringer Jay. This post is also an open thread. I welcome my readers to post any comments or additional links relating to any space issues, even if unrelated to the links below.

  • On this day in 1998, the first module of ISS was launched from Baikonur
    Dubbed Zarya, it was built by Russia but paid for by the U.S., which still owns it. Though it is the oldest module on ISS, it is the Russian Zvezda module, launched two years later, that presently has the stress fractures in its hull from which the station’s atmosphere is leaking, and which threaten the station’s survival in the next four years.

Bigoted academia upset that Trump won’t allow them to push the racist DEI agenda

Lysenko with Stalin
Trofim Lysenko (on the left), preaching to Stalin as he destroyed
Soviet plant research by persecuting anyone who disagreed with him,
thus causing famines that killed millions. He is now the role model for
today’s entire science community.

Cue the world’s smallest violin! An article today in the journal Science proves once again that science has nothing to do with what that journal now publishes. The headline:

‘This is censorship.’ Conference requires abstracts to comply with Trump anti-DEI order

It seems scientists submitting abstracts to the annual Lunar and Planetary Science Conference (LPSC) in Texas are upset because the Trump administration will not allow any papers to include any mention of diversity, equity, or inclusion (DEI) as a topic.

The Lunar and Planetary Science Conference (LPSC), hosted annually by the Lunar and Planetary Institute (LPI) in Texas, last week announced a new requirement for the upcoming 2026 conference: All submitted abstracts must comply with executive orders from the administration of U.S. President Donald Trump. His 20 January executive order called DEI “illegal and immoral discrimination programs” and terminated both federal DEI programs as well as grant funding for DEI initiatives. The conference policy follows moves earlier this year by LPI’s parent organization, the Universities Space Research Association (USRA), to scrub DEI-related content—including archived LPSC abstracts—from its websites.

Researchers are fuming, saying LPSC is doubling down on its previous decisions, and prioritizing avoiding trouble with the government over intellectual freedom. “This is censorship,” says planetary scientist Paul Byrne of Washington University in St. Louis. “Even if the percentage of people who would normally write a DEI abstract is small, a much larger percent are pissed off.”

In other words, the science community wants to support DEI racial discrimination, because it is designed to favor the racial and sexual groups they favor. To them it is more important to infuse these bigoted ideas into all science, rather than actually report real research about the solar system and planets.

What might be the weirdest crater on Mars

What might be Mars' weirdest crater
Click for original.

Cool image time! The picture to the right is taken from a global mosaic created from images taken by the wide-view context camera on Mars Reconnaissance Orbiter (MRO). The original source image was probably a photograph taken on February 15, 2020.

I normally begin with an image from MRO’s high resolution camera, but the only images that camera took of this crater did not show it entirely. This context camera shows it in all its glory, what to my eye appears to be one of the weirdest craters I’ve seen on Mars.

First, note its oblong shape — 5.5 miles long and 3.7 miles wide — which appears to narrow to the southeast. It certainly appears that if this crater was caused by an impact, the bolide came in at a very low angle from the northwest, plowing this 700-foot-deep divot as it drove itself into the ground. Research has shown that an impact has to come in almost sideways to do this. Even at slightly higher angles the resulting craters will still appear round.

But wait, there’s more!
