This post from GW Johnson reports on a study of Starship and it's broadside deceleration from Low Earth Orbit.

The pdf of the study is available here:
https://www.dropbox.com/scl/fi/t2qyn954 … otymr&dl=0

Email from GW:

In the process of looking at the 1-stage/2-way Mars surface-orbit transport
thing,  I was considering a tubular-shaped thing that would enter and
descend sort of like Starship,  but land on its side,  not its rear end.
To do that,  I had to create a spreadsheet that helped me estimate
hypersonic drag area (CD x A) as a function of angle of attack.  To check
it out and verify it,  I used it on my best-guess data for SpaceX's
Starship v.3 prototypes in flight test.  A pdf file of these results is
attached.  It is postable on the forums,  if you like.

These results indicate that SpaceX is really pushing the bare stainless on
the leeside in terms of recommended service temperature for most
300-series stainlesses.  Higher speed entries are inevitably going to need
heat shielding,  even on the lee side. The stagnation heating leads to
temperatures beyond what alumino-silicate ceramics can endure.  That means
their ceramic tiles are probably similar to the outer layer of the
Tufroc tiles used on the nose and leading edges of X-37B.

HULL, England (AP) — Karl Bushby embraced his weeping mother in his arms Monday as he returned to his northern England home to complete a 28-year odyssey to walk around the world.

“Where have you been?” his mother, Angela, asked as he arrived outside the home he left in 1998 that was now decked with a banner saying “Welcome Home Son.”

He didn’t need to tell her.

Bushby set out from Punta Arenas, Chile, on Nov. 1, 1998, and walked 31,000 miles (50,000 kilometers) across four continents and 30 countries to get home. He navigated shifting ice over the Bering Strait and swam across the Caspian Sea and English Channel to avoid taking a boat or plane — or any transport — to propel him forward.

He vowed not to return until he could complete the journey on foot. It was an eye-opening adventure full of danger and drudgery that was interrupted for years at a time by the unexpected: the 2008 financial crash that sapped funding from sponsors, the 2020 COVID-19 pandemic and mountains of bureaucratic red tape to get across international borders.

A trek made possible by kind strangers

On the final day of the journey, Bushby pushed his cart toward a hero’s welcome at City Hall before setting off for the last stretch to see his mother.

“Sorry to keep you waiting,” he joked to the crowd of hundreds who cheered his arrival. “Is that it, is it done?”

The ex-paratrooper said he looked like he was 10 years old when he left his mother’s row house at the age of 29. He returned at 57 — softer, grayer and weathered, but far more worldly.

“They say it takes a village but literally it took a world to get me here,” Bushby said. “The kindness of strangers, so many, from individuals to nation states to get me back here today. I didn’t do this alone. There was a big team. The biggest team. Earth.”

In 28 years of walking, Karl Bushby has overcome jungle, desert and red tape. Now he’s nearly home
2 MIN READ

Karl Bushby’s 28-year walk across the world is ending. A look at the trek, by the numbers

The idea started with a birthday card from his dad

Bushby had a thirst for adventure, but his mission only came into focus when his father, Keith, sent him a birthday card in the mid-90s. His dad, an army veteran himself, mentioned an argument two special forces troops had about the possibility of walking from London to New York over the Bering land bridge, believed by some scientists to have been used by early humans to migrate from Asia to the Americas at a time of lower sea levels.

AP correspondent Julie Walker reports on a man who spent 28 years walking around the world and now he’s finally coming home.

Perilous jungles, scorching deserts and frozen tundra slowed him down, but bureaucratic holdups brought his adventure to a halt for long periods.

Bushby originally calculated the distance could be covered in about five years, but he knew that was unrealistic.

“You just dump a whole bucket full of reality on that,” he said. “We suspected that it was 12 years plus. And the plus was a big plus. But never in our wildest dreams would we ever have imagined 28 years.”

Danger on land and sea followed by border problems

He dodged Colombia’s armed conflict in the dangerous Darién Gap, the roadless and rugged jungle, rainforest and mountains between South and Central America in 2001, and was then jailed for 18 days after crossing a restricted border zone in Panama.

After being airlifted to safety during the 56-mile (90-kilometer) Bering Strait crossing in 2006 with American adventurer Dimitry Kieffer, they started again and faced a standoff with a polar bear, survived near-death plunges into freezing waters and almost lost all their supplies when their sleds plunged in the sea. After managing the rare crossing, the pair were jailed and faced deportation for entering Russia illegally.

It took Bushby almost 10 years to make his way through Russia in fits and starts because of visa struggles and weather that only allowed travel a few months a year. When Russia denied him a visa in 2012, Bushby walked in protest from Los Angeles to the Russian Embassy in Washington, D.C., which eventually led to him getting the proper paperwork.

Family firsts and a long-awaited reunion

Bushby has met several times over the decades with family members who have met up with him on his journey. He was greeted on the beach in Dover by his father and brothers after crossing the channel last month.

He reunited with Adam, his 36-year-old son from an early marriage whom he had rarely seen, and he met his 12-year-old granddaughter for the first time, which he said was amazing.

Bushby hadn’t seen his mother in a decade, setting the stage for an emotional and somewhat awkward reunion captured amid a throng of cameras and a documentary film crew.

“Behave yourself, mother,” he joked, as his mother wrapped her arms around him and wept. “Get yourself together.”

He said he had long tried to imagine that moment he would return to find his mother at the gate where he left her so long ago. He said it was an emotional reunion that was “one great, big, blurry mess” he was trying to process.

“It was kind of almost shocking to see my mother after so long,” he said at a news conference later. “She’s changed a lot. We’ve all changed a lot in that time.”
Next steps for a man who walked millions

In the final days of his trip, Bushby spoke of his anxiety over the trip ending, not knowing what he would do next and coming to terms with having to live in his mom’s basement.

“It’s like stepping across the event horizon into a black hole,” he told The Associated Press. “I have no idea what’s about to happen in my life.”

There will be plenty to keep him busy. Six speaking engagements are scheduled in the next two months, a sequel to his memoir “Giant Steps” is due and German filmmaker Werner Herzog is making a documentary on his trek.

He expects to struggle with the ups and downs other adventurers have experienced after long journeys.

“The only way I think, you know, you get over that is just get another mission, another passion and get busy,” he said. “That’s what I intend on doing.”

I suspect that the problem that has shown up recently may have to do with our parser's attempts to create the search table that is an important part of our service.

#6 Re: Science, Technology, and Astronomy » Cartesian Coordinate Systems Conventions for SpaceCraft » Yesterday 08:06:28

This post is intended to contain a short summary of coordinate systems used for space craft in development and in service, in 2026.

Spacecraft Z-Axis Conventions Summary

In standard spacecraft and aerospace engineering, the assignment of the Z-axis depends on whether you are using a body-fixed coordinate system (relative to the vehicle itself) or an orbital reference frame (relative to its position in space).

1. Spacecraft Body-Fixed Coordinate Systems

For attitude control, structural analysis, and moments of inertia, spacecraft generally adhere to right-handed Cartesian coordinate systems (X, Y, Z):

NASA / AIAA Standard Body Frame:

    X-axis: Typically aligned with the longitudinal axis pointing forward (toward the nose or primary direction of thrust).

    Y-axis: Points to the starboard (right) side of the vehicle.

    Z-axis: Points downward (ventral side) perpendicular to the X-Y plane, completing the right-handed triad.

Alternative Launcher / Structural Convention:

    In some launch vehicle architectures, the longitudinal axis along the height of the rocket is designated as the Z-axis, with X and Y forming the transverse cross-section plane.

[h][color=#0055AA]2. Orbital Reference Frames (L V L H / Nadir-Pointing)[/color][/h]

When a spacecraft is operating in orbit and maintaining a local vertical orientation, orbital reference frames dictate sensor and antenna pointing:

Local-Vertical Local-Horizontal (LVLH):

    Z-axis: Points directly toward the center of the primary body (the nadir vector, downward toward Earth).

    X-axis: Points in the direction of orbital velocity along the orbital plane.

    Y-axis: Points along the orbit normal to complete the right-handed system.

3. Principal Axes of Inertia
For dynamics and control (I_xx, I_yy, I_zz), the Z-axis frequently represents the axis of symmetry for cylindrical or axisymmetric spacecraft, where spin is established around the principal Z-axis to maximize gyroscopic stability.

This topic is offered for NewMars members to collect knowledge about coordinate systems in use for spacecraft.

The subject has become necessary because GW Johnson is moving steadily from theoretical spacecraft design to the real thing.

Post #3 will contain a brief Gemini summary of the coordinate systems that are in play on Earth and in space in 2026.

It appears that the coordinate systems are literally all over the place.

However, a team building a space craft needs an agreed-upon coordinate system.

At present, GW's design follows the spin stabilized mode described in Post #3, but the location of Positive or Negative Z is not yet established.

The difference matters.

On Earth, in the assembly room, the heat shield is down (negative Z) and the docking collar is up (positive Z)

In flight, the heat shield is in front (positive Z) and the docking collar is in back (negative Z)

The (small) project team is waiting for GW Johnson to decided which is which for this particular spacecraft.

#13 Re: Meta New Mars » offtherock postings » 2026-11-03 11:00:46

For offtherock re responses ....

You've asked a really ** good ** question in https://newmars.com/forums/viewtopic.ph … 93#p242593

The Admins are supposed to read everything, but in practice few of us have the time to actually do that.

I try to at least look at ever post to get a sense of what is going on in the forum, but I certainly don't have time to read everything by every member. On he other hand, I read every word that RobertDyck posts and the same for GW Johnson and Calliban and lately GW Muller.

The reason is straight forward... these authors seem (to me at least) to be advancing the mission of the forum as part of the Mars Society. We have members who use this forum as a private blog.  Under the very tolerant leadership of SpaceNut (Senior Administrator) it is very rare for anyone to receive guidance to post differently.  Thus we have a lot of content that is of interest only to the writer.

This forum has the potential to record and report readership.  That feature has been on the to-do list since at least 2024, when we did a major update to the software.  kbd512 and I simply ran out of steam, and then the Mars Society server crashed, and then ** we **crashed due to a hacker, and we never got bsck to the readership feature.

I think that if you want to build a following, you can invite persons who you think would be interested in your writing to join.

There is another possibility ... it is possible that current members are reading your posts, but finding they agree with it, and in the absence of a "Like" feature (which we started ti implement in 2024) they simply go on to the next post.

Finally, if any of our authors would like to build up an interactive subgroup, it would appear to me to make sense to pay attention to the other members who are posting.

The general theme of this forum seems to be we have talented folks who like to write about subjects that are of interest to them, and they are selective about how much time the spend on subjects that are not of interest.

However, this forum is open to the Internet so a reader not named "Calliban" will not know what you are talking about.

Here is a follow up:

Vertical Wind Torus: Integrated Visual Systems for the Flight Experience

The Shared Experience: Duct-Integrated Displays vs. Personal VR
A critical design choice for maximizing the entertainment value is how the environmental imagery is displayed.

Personal VR Goggles (The Isolated Flight):

  • Advantage: High resolution per eye, capable of perfect immersive perspective.

  • Disadvantage: Isolates the pilot; observers see nothing; adds weight and complexity to the flight gear; risks spatial disorientation during complex maneuvers.

Surface-Integrated Visualization (The Collective Flight):
By lining the curved upper section of the torus (the flight regime) with modern display technologies (e.g., curved LED panels or multiple projection mapping sources), the entire environment is transformed.

  • Shared Perception: The pilot, launch crew, and observers all see the same simulated environment, enhancing the reality of the experience.

  • Safety: Pilots have unimpeded vision and situational awareness within the physical duct.

  • Versatility: Displays can change rapidly between any environment: Earth's Grand Canyon, ancient Mars, or purely abstract lighting landscapes.

  • Durability: While requiring more surface area than VR headsets, the visual system is physically integrated and not prone to falling or pilot-induced damage.

Technical Implementation Challenge
The main challenge lies in the sheer surface area of the upper toroidal arc. This requires significant data bandwidth and precise calibration to minimize seams between displays and provide a smooth, coherent image at operational glidespeeds. However, on a settled Mars with access to advanced composite materials and microelectronics fabrication, these are surmountable engineering hurdles.

For RobertDyck .... following up on the idea of an entertainment facility on Mars, here is output from a conversation with Gemini:

A key discovery for me is the benefit of using Argon instead of Nitrogen!

file.php?id=183

The source for the above image is a publication. I will try to show the references.

Vertical Wind Torus for Martian Human Glider Flight

Overview and Facility Concept
To provide a psychological and recreational outlet for Martian residents, a vertical toroidal cavern habitat can be configured as a continuous closed-loop flight tunnel. Rather than body-only skydiving, this facility is scaled for full hang glider human flight.

Atmospheric Physics & Argon-Rich Habitat Mix
* Habitat Total Pressure: 0.50 Bar (50,000 Pa)
* Oxygen Partial Pressure: 0.21 Bar (~42% molar share)
* Inert Argon Partial Pressure: 0.29 Bar (~58% molar share)
* Temperature: 20 degrees C (293.15 K)

Gas Density Calculation
Using the ideal gas law:
Density = (Pressure * Molar Mass) / (Gas Constant * Temperature)

* Molar Mass of O2 = 32.00 g/mol
* Molar Mass of Ar = 39.95 g/mol
* Average Molar Mass of Mix = 36.60 g/mol (0.0366 kg/mol)

Calculated Habitat Air Density = 0.75 kg/m^3

Flight Aerodynamics Comparison

  • Earth Sea Level Air Density: 1.225 kg/m^3

  • Mars Habitat Air Density: 0.750 kg/m^3 (61% of Earth sea level)

  • Raw Mars Outside Density: 0.020 kg/m^3 (35x thinner than habitat)

  • Glider Trim Cruise Speed (Earth): 35 km/h (10.0 m/s)

  • Glider Trim Cruise Speed (Mars Torus): 45 km/h (12.5 m/s)

Structural Layout

  • Top Section (Flight Zone): Wide clear-span upper arc of the vertical torus designed for smooth laminar airflow, launch ramps, and glider turns.

  • Bottom Section (Machinery & Circulation): Houses industrial axial blowers, flow straighteners, and heavy safety protective grates to prevent any debris from entering the fan stages.

#17 Re: Meta New Mars » RobertDyck Postings » 2026-11-03 08:22:34

For RobertDyck re flight on Mars (or the Moon for that matter)

There is a time honored way to provide humans with flight opportunities on the Moon and Mars.

It has been done on Earth for many years.

On Earth the movement of the atmosphere has provided flight opportunities where land obstructs the flow of air.

On Earth, humans have flown to high altitudes so they can jump out and experience "flight" while passing through the standing air on the way down.

What I am thinking about in your vision is the use of powerful electric motors to create wind flow that is strong enough to hold up a human in the mouth of the air tube.  The experience of the subject would be identical to flight falling from an aircraft, and a ** lot ** safer.  The air in that scenario is breathable, so no extended pressure adjustment is needed.

I'd be interested in your analysis of what it would take to provide the same experience for a Mars resident in a 1/2 Bar chamber.  The gravity is less, and the air density is less, so it's not clear (to me at least) how the experience on Mars would compare to what is done already on Earth.

Beyond the simple simulated aircraft drop flight experience, it would be a lot more satisfying to be able to pilot a small glider in a flow of 1/2 Bar air.  You can use Gemini, ChatGPT or CoPilot to create images showing what a flight experience might be like if you designed a suitable system.

Come to think of it, that idea might even work on the Earth.  I presume no one has invested in such a system because the Earth provides so many opportunities on the surface.  However, in a location on Earth with limited wind, or temperatures that are too low for comfort, an indoor glider experience might be fun and good exercise as well.

Folks in the Middle East could have afforded to build such a system before the present era.

At the Seventh Manned Spaceflight Conference in Beijing, officials, including Wang Xiang, chief designer for the lunar exploration program, laid out the country’s most publicly detailed plans yet for a series of missions leading up to a crewed lunar landing “before 2030.”

China’s lunar landings will involve a lunar-orbit rendezvous similar to what NASA did in the 1960s and early 1970s with the Apollo program. However, lacking a rocket as powerful as the Saturn V vehicle, the crew and lunar lander will launch separately to the Moon.

According to slides shared on social media, the current plan involves:

    An uncrewed test of the Long March 10A rocket (a single-stick variant, with no boosters) and the Mengzhou spacecraft to low-Earth orbit. Target: early 2027

    An uncrewed test of the larger Long March 10 rocket (a core stage with two boosters) and the Lanyue lunar lander, including descent/ascent from Moon’s surface. Target: 2028

    A concurrent launch of two Long March 10 rockets, one carrying uncrewed Mengzhou and the other the Lanyue vehicle; they will dock in lunar orbit. Target: 2029

    Dual launch of Long March 10 rockets, this time with crew on the Mengzhou spacecraft, leading to crewed landing mission. Target: “Before 2030”

The public release of this new information provides a timeline for gauging China’s technical progress in its efforts to land humans on the Moon before 2030 and beat NASA and the United States back to the lunar surface.

Notably, the plan (for now, at least) omits a mission similar to Apollo 8 or Artemis II, which involved a crew flying out to the Moon and either entering orbit or passing close by before returning to Earth. The Mengzhou vehicle should still get a workout closer to Earth with humans on board as part of missions carrying astronauts to Tiangong, China’s space station in low-Earth orbit.

China’s program has been largely opaque

NASA has set a target of landing humans on the Moon by 2028, a year or so ahead of China. The United States, which has been working on the Space Launch System rocket for 15 years and the Orion spacecraft even longer, has a more established rocket and crew vehicle.

But there are major questions surrounding the development of a lunar lander, for which both SpaceX and Blue Origin have multibillion-dollar development contracts. Depending on how these projects go, a US lunar landing could be delayed to 2030 or even later.

Although it is virtually impossible for outsiders to glean information about technical milestones achieved inside China’s space program, the country is clearly making credible progress toward reaching the Moon. For example, in August 2025, the China Manned Space Agency successfully tested a high-fidelity mock-up of its 26-ton Lanyue lunar lander. The test used giant tethers to simulate lunar gravity as the vehicle fired its main engines and fine-control thrusters to land on a cratered surface and take off from a location near Beijing.

Recently, the Mengzhou spacecraft for the 2027 test atop a Long March 10A rocket arrived at the Wenchang Space Launch Site in Hainan, China, where the mission will launch.

US government assessments of the Chinese space program are restricted, but lawmakers are clearly taking the threat seriously. In the last 12 months, the US Congress and White House have given broad latitude to NASA Administrator Jared Isaacman to streamline the Artemis Program to land humans on the Moon. He has moved swiftly to cancel the Lunar Gateway space station and planned upgrades to the Space Launch System rocket. And just last week, Isaacman announced plans to help Blue Origin develop a lunar lander by finding a way to boost the Orion spacecraft into low-lunar orbit.

“We have the mandate, we have the resources, and the support from our stakeholders to be able to execute, and that’s what we intend to do,” he said at the time.

For a couple of years, it has been clear that China has made a major commitment to landing astronauts on the Moon, preferably before the United States returns to the lunar surface, to score a major geopolitical win. Beyond this near-term competition, both NASA and China’s space program are building capabilities to establish a long-term presence at the Moon’s South Pole. As part of this second phase of the contest, Isaacman committed NASA to the development of a base on the surface of the Moon over the next decade.

For Void re Post #4.... https://newmars.com/forums/viewtopic.ph … 75#p242575

Please help me to understand how your latest post might be advertised in the index.

"apple peel" by itself does not seem adequate to cover your vision.

The use of your ideas that I see is not on Earth, but instead in open space, where rock can be heated into a molten ball by solar energy.

Once a worker/artisan has a ball of molten material floating in zero gravity, some of your ideas might seem practical.

Perhaps a molten ball could be rotated (somehow) to allow for the kind of peeling you showed.

You might be able to try some of your ideas at a pool of molten lava on Earth.

Perhaps humans have experimented with harvesting lava in past centuries?

Lava still flows freely on Earth today, in 2026, at multiple locations.

For AstroCello13 re QR code hypothesis...

A test of a multiple line QR code appears to have succeeded.

The QR code below was read by an android phone and the output appeared to be separate lines.
The question under study was whether line breaks are preserved by the Google default QR code generator.

Your tests of this QR code will be welcome.

For NewMars members:

Your tests of reading of the QR code in this post are both welcome and needed.

You ** should ** be able to see four separate lines of robot arm configuration.

The language in use was developed years ago by the inventor of the LynxMotion line of robots.

For RobertDyck re new topic on flight in air reservoir on Mars...

This is certainly an interesting new topic!

Please add a post with information about the density and pressure of the air in the reservoir.

There will certainly be reservoirs of air on Mars, and in every location humans travel away from Earth.

It is fun seeing Robert Heinlein's name back in print.  It's been many decades since I saw him at an L5 event in San Francisco.

Your athlete flyers will have to deal with the difference between pressure inside the reservoir and their normal living pressure on Mars.

One option might be to wear a breathing apparatus able to lower the reservoir pressure to 1/2 bar, and then (somehow) push the exhaust CO2 back out into the reservoir.

It would definitely be interesting to see Heinlein's text in presenting this idea.  Did he deal with pressure difference?  Was he even aware of the need for it?

Again! Interesting new topic!
