Archeology on ISS?

Archeologists have now published a paper outlining what they call the first archeology project in space, documenting the changes that have occurred at six different locations on the International Space Station during a 60 day period.

[The archeologists] had the astronauts use adhesive tape to define one-meter areas of the International Space Station and document them with daily photographs to study how the spaces were used over 60 days in 2022. The squares were placed in a handful of work and leisure locations on the space station, including the U.S. galley table, workstations, experimental EXPRESS racks and on the wall across from the latrine where astronauts kept their toiletries.

The team’s findings provide the first glimpse into how astronauts adapt to life and conduct research without gravity, how international cooperation plays out in the tight quarters, how they use their space for work and leisure while in orbit, and more. By cross-referencing the photos with astronaut activity reports, the researchers found that the area near the exercise equipment and latrine, while not designated for any particular purpose, had been used as storage for toiletries, resealable bags, and a rarely used computer. The equipment maintenance area was actually used for storage, with little maintenance carried out there. [emphasis mine]

This research has some value, but on the whole its substance I think is overrated. When you build a home, the rooms have generally accepted purposes (kitchen, bathroom, bedroom, office, living room) but with some of those rooms it is expected that the homeowners will bring their own needs and desires to the place and use them as they please. The study above demonstrates this perfectly with the highlighted sentence. Though one area was designed to be a repair workbench, the astronauts found it more convenient or necessary to all such work elsewhere, and repurposed the maintenance area more practically.

At the same time, neither a space station nor an interplanetary spaceship are like homes. Both are actually entire worlds packed into a small space, so a lot of thinking has to go into designing them. It is in this area this research has some value. We are still learning what “rooms” will generally be needed in such long term space vessels, and this study can provide some data for this purpose.

Even so, I remain skeptical. It will likely be much cheaper and faster to simply talk to the astronauts who have lived on ISS to get their imput on how the interior space of a future interplanetary spaceship or station should be designed. In fact, the best thing to do would be to hire astronauts to help with the design process. That’s what the Soviets did in designing Soyuz. Asking archeologists for this information is nice, but seems very distant from the real issue. And it creates work on the station that might be better used doing something else.

Scientists propose much more efficient method for warming Mars to habitable temperatures

Global map of ice scarps on Mars
Global map of known exposed scarps of ice on Mars. North and south of the
white hatched lines, near surface ice and glaciers are common.

Scientists have now proposed much more efficient method for warming the climate of the planet Mars by as much 50 degrees Fahrenheit, enough to melt much of the near-surface ice in the middle latitudes and thus make the planet habitable.

This new method, using engineered dust particles released to the atmosphere, could potentially warm the Red Planet by more than 50 degrees Fahrenheit, to temperatures suitable for microbial life—a crucial first step towards making Mars habitable.

The proposed method is over 5,000 times more efficient than previous schemes to globally warm Mars, representing a significant leap forward in our ability to modify the Martian environment. What sets this approach apart is its use of resources readily available on Mars, making it far more feasible than earlier proposals that relied on importing materials from Earth or mining rare Martian resources.

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

PLD targets October to begin construction of launch facilities in French Guiana

The Spanish rocket startup PLD is now targeting October to begin construction of its launch facilities in French Guiana, using the long abandoned launch site of France’s first rocket.

PLD Space plans to start building launch facilities for its Miura 5 rocket in October from the Diamant site at Guiana Space Centre, cofounder and chief business development officer Raúl Verdú told SpaceNews. Diamant has been dormant for decades after once being used for the French rocket of the same name, and “in the area where we are there is nothing,” Verdú said, “we have to do everything from scratch.”

The company hopes to do its first orbital launch in 2025.

Control of the French Guiana spaceport reverted back from Arianespace to the French space agency CNES (which has always owned it) in 2022, and since then CNES has signed deals with seven European rocket startups. PLD appears to be moving the fastest towards the first private commerical launch there.

Brooklyn startup wins NASA contract to develop wireless communication technology for use on the Moon

The Brooklyn startup Yank Technologies has won a $150K NASA contract to develop wireless communication technology for use on the Moon.

Yank Technologies plans to develop two systems for the lunar surface: Wireless Power Receiver Converters for lunar rovers and Resonant Inductive Connectors for high voltage power transmission on the Moon and Mars.

The Wireless Power Receiver Converters are designed to improve rover efficiency and reduce mass by integrating multiple converters into a single-stage converter that supports various voltages. These converters also enhance charging reliability by accommodating misalignment and varying distances.

Resonant Inductive Connectors are designed to maintain reliable connections with high-voltage lines despite the presence of lunar regolith or Martian dust. Unlike traditional connectors, which are prone to wear and unreliable connections, these connectors are built to withstand harsh environments.

The award was likely made in late June as part of an small business award of similar development contracts to about 250 companies. Though wireless techology is well established, in this case the goal is to lower the weight of this equipment while making it space-hardened. While such work is routinely required, this contract highlights the detail work necessary for making operations on an alien planet practical.

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.

Rocket Factory Augsburg completes 2nd static fire test of first stage

The German startup Rocket Factory Augsburg has apparently completed a second static fire test of the first stage of its RFA-1 rocket.

The test occurred on the launchpad the company will use to launch at the Saxaford spaceport in the Shetland Islands. Video of the test is available here.

The test itself lasted for approximately 15 seconds and included five of the company’s Helix rocket engines. While this is one more than the previous test, it’s still short of the full nine-engine complement that will be utilized aboard every RFA ONE first stage.

A full static fire test of all nine engines is still necessary before launch. The rocket’s upper stage has already completed its full test compaign and is on the way to Saxaford for stacking.

The hope is that the first orbital test launch will occur before the end of the year, but for that to happen Rocket Factory must get its launch license from the UK’s Civil Aviation Authority (CAA). Based on how slow it approved its only previous launch license for Virgin Orbit (bankrupting the company because it took so long), no one should be expect a launch this year.

Chinese Long March 6A upper stage breaks up into debris shortly after deploying satellites

Ground and satellite reconnaissance data now indicates that the upper stage of the Chinese Long March 6A rocket that on August 6 launched the 18 satellites in a proposed Chinese 14,000 satellite internet constellation broke up into numerous pieces shortly after deploying the satellites.

The detection was made by the company Slingshot Aerospace, which tracks orbital spacecraft looking for the appearance of this kind of space junk.

This is actually the second time recently that an upper stage of a Long March 6A has broken up shortly after launch. In December 2022 the same thing was detected following a November launch.

All told, this relatively new Chinese rocket has launched seven times, and has had its upper stage break up twice. Apparently, China not only doesn’t care if the lower stages of its many rockets crash on top of its own citizens, it is quite okay with littering near-earth orbital space with debris. It needs to fix the upper stage of this rocket now, so such break-ups no longer occur.

Gaia space telescope identifies more than 350 asteroids with candidate moons

Using the Gaia space telescope, astronomers have identified 352 asteroids that the data suggests have smaller satellite asteroids in orbit around them.

In its data release 3, Gaia precisely pinpointed the positions and motions of 150 000+ asteroids — so precisely that scientists could dig deeper and hunt for asteroids displaying the characteristic ‘wobble’ caused by the tug of an orbiting companion (the same mechanism as displayed here for a binary star). Gaia also gathered data on asteroid chemistry, compiling the largest ever collection of asteroid ‘reflectance spectra’ (light curves that reveal an object’s colour and composition).

These results need to be confirmed by direct observation, as this method does involve some assumptions and uncertainties. If these numbers are confirmed however it will give planetary scientists a better census on the percentage of asteroids with moons, which in turn can be used to create better models of the formation of the solar system as well as the evolution of asteroids over time. At the moment scientists predict about one out of every six asteroids will have a moon. This data suggests that number might be high.

SpaceX sets August 26, 2024 as new launch date for Polaris Dawn private manned mission

Jared Isaacman
Jared Isaacman

According to a post on X yesterday, SpaceX has rescheduled the launch of the private Polaris Dawn manned orbital flight to August 26, 2024. The flight is financed entirely by billionaire Jared Isaacman, who will also command the mission (his second in space).

The mission will launch on a Falcon 9, with the Dragon Resilience spacecraft carrying four private astronauts. During the orbital flight the capsule will attempt to fly as high as 870 miles, the highest any human will have flown since the Apollo missions. It will then attempt the first spacewalks by a private citizen ever. They will open a hatch, and Isaacman will push himself outside.

The schedule change from July 31st is almost certainly due to the uncertainties surrounding the return of Starliner from ISS, which have also caused uncertainties in the launch date of SpaceX’s next manned mission to ISS. With only two launchpads in Florida for both missions (plus other required launches), a lot of juggling has been required.

August 7, 2024 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.

 

 

  • Another relatively boring press release of an image from Europe’s Mars Expresss orbiter
  • I post so few images from Mars Express because Europe releases so few, and when they do, they don’t usually provide enough good information to understand what one is looking at. For example, this release never really tells us the global location of the picture, info that is crucial to understanding it. I could look it up, but the image itself is just not that interesting.

Students win settlement against college for censoring their speech illegally

One poster that Clovis Community College tried to censor
One of the posters that Clovis Community College officials agreed to
“gladly” remove because it made some students “very uncomfortable.”

Bring a gun to a knife fight: Back in November 2021 three students at Clovis Community College who were also members of the college club for Young Americans for Freedom (YAF) got permission to put up posters on campus showing in detail the historic and documented horrors of communist rule worldwide. The picture to the right shows one such poster.

Soon thereafter some people supposedly complained that the posters made them “uncomfortable.” Despite the fact that everything in the posters is factually true, the then college president Lori Bennett ordered the posters torn down, claiming she did it because they weren’t specifically a “club announcement.

In August 2022 the students sued [pdf] with the help of the Foundation for Individual Rights and Expression (FIRE), noting that Bennett’s policy was not only inconsistent and arbitrarily, it was mostly used to block conservative political statements college administrators did not like.

The students have now won a settlement in court.
