Barren Mars

Panorama by Perseverance on sol 1400, January 27, 2025
Click for full resolution panorama. For original images, go here, here, and here.

Overview map
Click for interactive map.

Cool image time! The panorama above was created by me using three pictures taken today (here, here, and here) by the right navigation camera on the Mars rover Perseverance. The top of the rover can be seen to the right, as well as its tracks.

The overview map to the right provides the context. The blue dot marks Perseverance’s present position. The white dotted line its past travel route, with the red dotted line indicating the planned route. The yellow lines indicate the approximate area covered by the panorama.

Though the planned route had the rover head west and then south, the rover team instead had the rover retreat eastward about 450 feet the past few days, where it sits now. At the previous western location the team had attempted to find a location to drill a sample core, but apparently the ground was not satisfactory. By retreating to this previous location it could be they think they will have better luck.

What strikes me about this hilly terrain just outside Jezero Crater is its barrenness. You would have great difficulty anywhere on Earth finding terrain so empty of life. On Mars however there is nothing but dirt and rocks, for as far as the eye can see.

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, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, 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

Strap-on booster of Long March 3B launched yesterday crashed next to home

9:53 am

Long March 3B
Long March 3B

One of the four strap-on boosters used by a Long March 3B rocket that was launched yesterday from the Xichang spaceport in southwest China ended up crashing right next to a home.

The TJS-14 satellite launched on a Long March 3B rocket from Xichang Satellite Launch Center on Thursday at 10:32 a.m. EST (1532 GMT; 11:32 p.m. local time). The satellite is safely on its way to geostationary orbit, but one of the rocket’s four strap-on side boosters fell to Earth in a populated area of Zhenyuan County in Guizhou province.

Security camera footage posted on the social media platform Sina Weibo captured the scene of two family members reacting to an explosion near their home that lit up the night sky. Fortunately, the booster, which exploded on impact, fell in what appeared to be hills above the house.

The video can be viewed here. While the booster apparently missed the house, any remaining hypergolic fuel in the booster posed a very serious health threat, especially if it was released as a gas. That fuel is extremely toxic, and can dissolve skin if it makes contact. I would expect that until a major clean-up occurred at the crash site, the people that lived in that home will have to evacuate.

China has said that it intends to replace all of its hypergolic-fueled rockets with liquid-fueled, and is expanding operations at its Wenchang coastal spaceport as well. When however these rockets stop launching from its interior spaceports remains unknown. It is likely in fact that toxic stages will continue to fall on the heads of Chinese citizens for years to come.

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.

Today’s blacklisted American: Queer protesters force cancellation of a speech against men playing women’s sports

2:45 pm

Olivia Krolczyk being silenced at Washington University
Olivia Krolczyk being silenced at Washington University

They’re coming for you next: Just because the majority of the country has chosen a different path opposing the queer agenda in schools and public facilities doesn’t mean the war is over. Far from it. A mob of protesters supporting the queer agenda in all things forced the cancellation of a speech at a Turning Point USA chapter event at the University of Washington earlier this week.

Olivia Krolczyk was unable to give her talk, “Protect Women from Men: The Threat of the Trans Agenda,” after protesters pulled the fire alarm and later smashed a window in the building. The university’s TPUSA chapter and the Leadership Institute hosted the event.

“The responsibility for interrupting last night’s event falls on those whose actions were disruptive and damaging, including breaking a window, graffiti in the building and wasting firefighters’ time with a false fire alarm,” university spokesperson Victor Balta told The College Fix in an email Wednesday. “Anyone who is identified to have been responsible for vandalism or property damage will be pursued through legal channels,” he said.

European rocket startups team up to send letter to ESA outlining their priorities

11:18 am

In a surprising joint action, six European rocket startups have sent a detailed letter to the European Space Agency (ESA) outlining several recommendations about policy required by these rocket startups in order for their industry to prosper.

The companies involved were HyImpulse, Latitude, MaiaSpace, Orbex, Rocket Factory Augsburg and The Exploration Company. The letter’s recommendations were wide-ranging and appeared focused on getting ESA to free up the industry from traditional European red tape.

  • Provide funding in the range of €150 million to a limited number of rocket companies, not all. The companies say that funding will make it possible for the winning companies to raise another €1 billion in private investment capital. Limiting the number of companies getting awards will also force competition and achievement. The awards should also be granted only after specific milestones are achieved, not based on promises of eventual achievement.
  • Ease access to launchpads both at French Guiana and in Norway and the United Kingdom. Right now French rule-making at French Guiana is hindering that access, and ESA rules about launches make it harder to use the new commercial spaceports in Norway and the UK.
  • Red tape must be reduced. For example, ESA should not set rules on the size of payloads, but give companies “the freedom to determine their payload capabilities, allowing market dynamics to drive innovation rather than imposing artificial requirements.”

That the German rocket startup Isar Aerospace did not sign this letter is interesting, especially since it is now only a few months from completing its first orbital test launch of its Spectrum rocket from the new spaceport in Andoya, Norway. It also has a twenty-year lease for that launchpad.

It is also interesting that the letter did not include the newly proposed orbital spaceport Esrange in Sweden. That launch site has been used for decades for suborbital tests. It is now attempting to make itself available for orbital tests as well. Its interior location however is likely the reason these rocket companies left it out. Too many issues for them to consider launching from there.

Engineers confirm OSIRIS-APEX successfully completed its second of six close fly-bys of the Sun

10:19 am

Engineers have now confirmed that the asteroid probe OSIRIS-APEX successfully completed its second of six close fly-bys of the Sun in September, using its solar panels to shield its instruments from the Sun’s heat and light.

On Jan. 23 the mission team completed its review of all the data recorded by the spacecraft and its instruments during the solar pass [about 46 million miles from the Sun]. “There were no surprises, and the spacecraft is operating well,” said Mike Moreau, OSIRIS-APEX deputy project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

As planned, on Sept. 2, 2024, OSIRIS-APEX passed through perihelion — the phase of its orbit closest to the Sun. The trajectory to Apophis takes the spacecraft much closer to the Sun than it was originally designed for. Between Aug. 1 and Oct. 13, the spacecraft was configured in a special orientation that uses one of the solar arrays to shade the most heat-sensitive components, keeping them within safe operating temperatures.

Because of the improvised orientation during the close approach, full data communications was not possible until months afterward. Only now have engineers completed their analysis.

OSIRIS-APEX original mission was to visit the asteroid Bennu and return samples from it to Earth. Once that mission was successfully completed, the probe was repurposed to go to the potentially dangerous asteroid Apophis when it makes its next close approach to the Earth in April 2029.

I have embedded below a short video showing the spacecraft’s journey to get to Apophis.

China and SpaceX complete launches

10:02 am

Both China and SpaceX successfully completed launches since last night.

First, China placed a classified technology communications test satellite in orbit, its Long March 3B rocket lifting off from its Xichang spaceport in southwest China. No further details about the satellite were released. Nor did China’s state-run press provide any information about where the rocket’s lower stages and four strap-on boosters, all using very toxic hypergolic fuels, crashed inside China. UPDATE: One of the four strap-on boosters crashed next to a home.

Then SpaceX this morning launched 23 more Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg in California. The first stage completed its 23rd flight, landing on a drone ship in the Pacific.

The 2025 launch race:

11 SpaceX
6 China

Space Perspective needs new investors

9:50 am

According to this news article today, the high altitude balloon company Space Perspective is in need of new investment capital, and its apparent lease default in the Cape Canaveral area is because the company has apparently shifted operations about ninety miles south because costs there are lower.

Space Perspective co-founder Jane Poynter told OBJ in a Zoom interview in December that although Port Canaveral “is our home port” and “we’re very committed to the community we work in” the company had been operating out of Fort Pierce, nearly 90 miles south, for several months. “They are having to struggle with how they balance what’s happening with the cruise industry and space industry growing like gangbusters,” she said of the Space Coast. “It’s so congested that we can’t actually stay there.”

While the company claims it is still moving forward, it has had to lay off most of its staff as it tries to find more investment capital. While it also claims it will return to full staffing when that investment arrives, the question is whether it will arrive. At this moment the default of $90,295 in rent to Titusville-Cocoa Airport Authority is not a good look at all.

AST SpaceMobile raises $400 million in capital

9:33 am

The direct-to-cell satellite company AST SpaceMobile has raised another $400 million in investment capital, giving it a total of $900 million in cash on hand for building its full constellation of its much larger second generation Bluebird satellites.

The operator now has more than $900 million of cash on its balance sheet to shift production of its Block 2 BlueBird satellites into a higher gear this year, after deploying five smaller Block 1 spacecraft to low Earth orbit (LEO) in September.

At about 223 square meters when fully deployed, a Block 2 satellite is significantly larger than Block 1, which spans 64 square meters, enabling 10 times the capacity to support up to 120 megabits per second (Mbps) peak data rates.

It has plans to launch 45 of these larger satellites in the next two years.

At the moment AST SpaceMobile and SpaceX are the only two companies offering direct-to-cell service. One component of SpaceX’s Starlink constellation has this capability, and the company has a deal with T-Mobile to use it to fill in gaps in its cell tower ground network. AST in turn has a deal with AT&T.

Report predicts both Boeing and Airbus will sell off their space divisions this year

9:23 am

According to an analysis of industry trends by the company Space Capital, it predicts that both Boeing and Airbus will sell off their space divisions this year.

According to Space Capital’s latest investment trends report released Jan. 23, these aerospace giants are struggling to maintain pace with the rapidly evolving space sector. “These divestitures by entrenched government contractors marks a pivotal moment in the space economy, as it changes the competitive landscape, establishes a new power broker system, and creates new opportunities and risks in the government’s extended capabilities in space,” the report states.

This prediction for Boeing is not a surprise, especially as the company has also recently announced it expects to take a $1.7 billion loss in the fourth quarter of 2024 from five different program in its Defense, Space and Security business unit.

Most of those charges will go towards two programs: $800 million for the KC-46A tanker and $500 million for the T-7A trainer aircraft. That leaves $400 million in charges for Starliner as well as the VC-25B presidential aircraft and MQ-25 drone.

Airbus’s space division is likely in trouble because of the failure of its Ariane-6 to compete successfully in the modern launch market. It has obtained some launch contracts, but not as many as expected because, as an expendable rocket, it costs too much to launch.

Peeling flood lava on Mars

12:09 pm

Peeling flood lava on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on October 2, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists label this “enigmatic terrain” because its origins are a bit difficult to decipher. The location is just north of the equator, so this is in the dry tropics of Mars, where no near-surface ice is found at all. The location is also in the middle of Elysium Planitia, one of the largest flood lava plains on Mars. Elysium is a largely featureless flat plain, where flood lava from the large giant Martian volcanoes covered a vast region.

Here however that top layer of flood lava appears almost like peeling paint that failed to stick to the underlying rougher terrain. In many places it is gone, exposing a stippled surface that is also likely flood lava but laid down either in a rougher manner or eroded over time to leave a rougher surface.

Congresswoman calls for moving NASA headquarters to Florida

9:29 am

Congresswoman Anna Paulina Luna (R-Florida) has now publicly repeated Governor Ron DeSantis’ call to move NASA’s main headquarters from Washington to Florida, doing so by sending Trump a letter noting the reasons why such a move make sense.

“I write to you in support of relocating NASA’s Headquarters from Washington, D.C. to Florida’s Space Coast,” Luna wrote. “While Washington, D.C., has historically been the home of NASA’s headquarters, the rapidly evolving space landscape demands a more integrated and efficient approach to space policy. Florida’s Space Coast, home to key facilities like the Kennedy Space Center and Cape Canaveral Space Force Station, is uniquely positioned to support this transformation and strengthen America’s leadership in space exploration.”

The lease for NASA’s headquarters building expires in 2028. The agency has already put out a request for proposals for building a new building from scratch, at great cost. I suspect that expensive project is about to die, and the lease expiration will provide the Trump administration and Congress the motive for reducing staffing at headquarters most significantly, as well as moving it elsewhere.

NASA quickly shutters its DEI offices

9:10 am

NASA has quickly complied with the executive order issued by Donald Trump right after taking office that demanded all Diversity, Equity, and Inclusion (DEI) offices within the federal government be shut down by January 22, 2025 at the latest.

In a memo to employees Jan. 22 obtained by SpaceNews, NASA Acting Administrator Janet Petro said the agency was working to close offices related to diversity, equity, inclusion and accessibility (DEIA) at the agency and cancel relevant contracts. “These programs divided Americans by race, wasted taxpayer dollars, and resulted in shameful discrimination,” she wrote in the memo.

The steps, she wrote, are intended to implement an executive order issued by President Trump hours after his Jan. 20 inauguration. The order called on federal agencies to terminate DEIA programs and positions related to them, calling such efforts “discriminatory” and an “immense public waste.”

That was followed the next day by a memo to federal agencies by Charles Ezell, acting director of the Office of Personnel Management (OPM), directing them to remove “outward facing media” related to DEIA programs by 5 p.m. Eastern Jan. 22 and to place employees of DEIA offices on paid administrative leave. The memo also requires agencies to provide lists of their DEIA offices and employees, as well as related contracts, by Jan. 23, and submit plans for laying off DEIA employees by the end of the month.

As of today it appears the NASA DEI websites have all been removed. It also appears that NASA is complying completely, unlike some government agencies that have tried to save its DEI programs and employees by changing their job titles. We should also expect the racist quota hiring system NASA instituted during the Biden administration to favor some races over others will now be dismantled. Couldn’t happen sooner.

What I have found interesting is the relatively lack of leftist protests — so far — for these actions. It will happen, of course but it also appears the general public won’t buy into it. The leftist propaganda press will highlight those protests, but since very few people trusts or even pays attention to that propaganda press any longer these protests will carry little weight.

Rocket Lab wins launch contract with German satellite constellation

8:58 am

Rocket Lab has won a launch contract with the German satellite constellation Orora Technologies,with the launch to occur only four months hence and place eight satellites into orbit.

The constellation is focused on monitoring wildfires for fire-fighting teams, and will eventually have 100 satellites in orbit.

OroraTech is developing a constellation of satellites with thermal infrared cameras that can provide 24/7 monitoring of wildfires globally, supporting better and faster wildfire response to protect forests, people, and infrastructure worldwide. The mission will deploy its latest plane of satellites called OTC-P1 to their current constellation, further expanding OroraTech’s capabilities to first responders, governments, and industry partners. The company will expand their constellation with up to 100 satellites in total by 2028.

If this launch goes as planned, expect Rocket Lab to win launch contracts for the rest of the constellation, a minimum of 11 more launches.

China launches 6th group of 18 satellites for its Spacesail internet constellation

8:52 am

China late yesterday successfully launched the sixth group of 18 satellites for its Spacesail internet constellation, its Long March 6A rocket lifting off from the Taiyuan spaceport in northeast China.

No word on where the rocket’s lower stages crashed inside China. The state-run report however touted proudly how the rocket uses liquid oxygen and kerosene, both of which are “non-toxic and pollution-free”. Apparently it has recognized the bad press it has gotten from crashing stages inside China that use very toxic hypergolic fuels.

The article noted that China plans at least ten launches in 2025 of the Long March 6A, likely as part of building this constellation of more than 1,200 satellites.

Fake news teams up with European childishness to attack Elon Musk

11:00 am

In what might be the stupidest and most fake slanderous attack yet on a supporter of Donald Trump, leftist fake news outlets PBS, CNN, MSN, and MSNBC have teamed up to accuse Elon Musk of making a Nazi salute during his inauguration day speech, when all he was doing was thanking Americans, from his heart, for voting Trump back into office. As he did so he placed his hand on his heart and threw it out to the crowd, in gesture of love and gratitude.

Very quickly the somewhat leftist Anti-Defamation League defended Musk, noting it was absurd and inflammatory to make such an absurd accusation when it was most clearly false and slanderous.

This of course hasn’t stopped Democratic Party politicians from spreading this lie. And in Germany the Deutsches Museum in Munich, Germany immediately and very childishly removed a picture of Musk that had been part of a permanent exhibit on space travel.

“It can always be problematic to honor living people in such a prominent position in an exhibition, because such a display can be seen as an uncritical tribute. However, a person’s lifetime achievements can often only be properly assessed in retrospect,” said a spokesperson for the Deutsches Museum.

What idiots. Musk’s own response on X to this fake controversy ginned up by these slanderers said it best:

Frankly, they need better dirty tricks. The “everyone is Hitler” attack is sooo tired

I personally think these leftist fools should keep doing this stupidity. No one buys it anymore, and every time they do it they put another nail in their own coffin, proving once again that they are unreliable, dishonest propaganda outlets that should not be watched for any reason.

Blue Ghost completes first main mid-course correction engine burn

10:22 am

Firefly’s Blue Ghost lunar lander has not only successfully completed its first major engine burn, raising its Earth orbit as it slowly moves towards the Moon, but successfully used a joint NASA-Italian instrument to pinpoint its location using Earth-orbiting GPS-type satellites.

Jointly developed by NASA and the Italian Space Agency, the Lunar GNSS Receiver Experiment (LuGRE) technology demonstration acquired Global Navigation Satellite System (GNSS) signals, and calculated a navigation fix at nearly 52 Earth radii: more than 205,674 miles (331,000 kilometers) from Earth’s surface. This achievement suggests that Earth-based GNSS constellations can be used for navigation at nearly 90% of the distance to the Moon, an Earth-Moon signal distance record. It also demonstrates the power of using multiple GNSS constellations together, such as GPS and Galileo, to perform navigation.

These results suggest that if all lunar orbiters had this instrument on board, they could all pinpoint their positions precisely and thus eliminate the chance of collision. It also suggests that it might not be necessary, at least immediately, to build a separate GPS-type constellation around the Moon. Earth’s systems could do the job.

Blue Ghost will spend 25 days in Earth orbit, when it will transfer to lunar orbit for several more weeks before attempting a landing.

Fast radio burst unexpectedly traced to dead and old elliptical galaxy

10:12 am

Location of Fast Radio Burst
Figure 4 from this paper [pdf].

The uncertainty of science: Using several radio telescopes working in tandem, astronomers have been able to identify the source galaxy of a fast radio burst (FRB) that repeatedly erupted throughout 2024, and discovered it came from a dead and old elliptical galaxy, not a younger galaxy as predicted.

[W]hile most FRBs originate well within their galaxies, the team traced FRB 20240209A to the outskirts of its home — 130,000 lightyears from the galaxy’s center where few other stars exist. “Among the FRB population, this FRB is located the furthest from the center of its host galaxy,” said Vishwangi Shah, a graduate student at McGill, who led the effort to pinpoint the FRB’s origins. “This is both surprising and exciting, as FRBs are expected to originate inside galaxies, often in star-forming regions. The location of this FRB so far outside its host galaxy raises questions as to how such energetic events can occur in regions where no new stars are forming.”

The small ellipse to the upper left of the giant elliptical galaxy (in yellow) marks the location of the FRB relative to its galaxy. Why it is so far outside remains a puzzle. The scientists consider two options: First, that the magnetar was once inside the galaxy but was kicked out at some point, and second, it simply could be inside a globular cluster that is too small to detect at this distance, two billion light years away.

Both explanations have problems and really don’t work.

Finland signs Artemis Accords

9:50 am

Finland today became the 53rd nation to sign the Artemis Accords. Based on the official statement from Wille Rydman, Finland’s minister of economic affairs, it appears Finland sees the accords as a way to encourage its own private space sector:

“Finland has been part of the space exploration community for decades with innovations and technology produced by Finnish companies and research institutions,” said Rydman. “The signing of the Artemis Accords is in line with Finland’s newly updated space strategy that highlights the importance of international cooperation and of strengthening partnerships with the Unites States and other allies. We aim for this cooperation to open great opportunities for the Finnish space sector in the new era of space exploration and in the Artemis program.”

The NASA press release still appears to focus on strengthening the Outer Space treaty, but I suspect that this Biden-imposed goal will change now that Trump is president. The original purpose of the accords as created during Trump’s first term was to work around the Outer Space treaty’s limitations on private ownership in space. Expect a return to that goal.

The full list of nations now part of this American space alliance: Angola, Argentina, Armenia, Australia, Austria, Bahrain, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Cyprus, Czech Republic, Denmark, Dominican Republic, Ecuador, Estonia, Finland, France, Germany, Greece, Iceland, India, Israel, Italy, Japan, Liechtenstein, Lithuania, Luxembourg, Mexico, the Netherlands, New Zealand, Nigeria, Panama, Peru, Poland, Romania, Rwanda, Saudi Arabia, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Thailand, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

I feel obliged to explain, if vaguely, the reason my posting has been relatively light the past few weeks. I have been struggling with health issues that have sucked all the energy out of me. Things have been improving, but for the rest of this week and next Diane will be recovering from knee surgery, and this will require my time above that of the website.

I will continue to report the news stories, including launches, that I think important, but essays might have to wait until things get back to normal at the Zimmerman household.

South Korea’s space bureaucracy attempts to encourage private sector development

9:38 am

South Korea’s space agency, the Korea Aerospace Administration, has announced a new effort to encourage that country’s private sector in developing rockets and satellites.

[A] plan will be established to link the National Space Council, the highest policy decision-making body overseeing government space policy, with the Aerospace Development Policy Review Committee. Systems will also be established for workforce training in aerospace and the designation of a space development mission center.

To establish an aerospace economic ecosystem, the participation of the private sector in the development and utilization of launch vehicles and satellites will be expanded. In the aviation sector, future aircraft technologies, including urban air mobility (UAM), will be secured, and localization of aircraft materials and components will be supported. To encourage smooth research and development (R&D) investments in aerospace corporations, the aerospace fund will be revitalized with improvements to regulations and support for overseas expansion.

Overall, a lot of this sounds like meaningless bureaucratic gobbledygook. The goal might be to expand the private sector, but the program still has the space agency running everything, from its new government-built Nuri rocket to its other satellite development programs.

Nonetheless, the desire to encourage the private sector is good. It could simply be that South Korea’s private sector is not mature enough yet to take the lead, and the agency by this announcement is working to push it forward.

General Atomics successfully tests fuels to be used in an in-space nuclear propulsion system

9:16 am

The company General Atomics announced yesterday that it has successfully tested the fuels it wants to use in an in-space nuclear propulsion system for transporting ships to the Moon and beyond much faster and more efficiently than is presently possible with chemical engines.

[General Atomics] executed several high-impact tests at NASA’s MSFC in Huntsville, AL. The nuclear fuel was tested with hot hydrogen flow through the samples and subjected to six thermal cycles that rapidly ramped-up to a peak temperature of 2600 K (Kelvin) or 4220° Fahrenheit. Each cycle included a 20-minute hold at peak performance to demonstrate the effectiveness of shielding the fuel material from erosion and degradation by the hot hydrogen. Additional tests were performed with varying protective features to provide further data on how different material enhancements improve performance under reactor-like conditions.

It has been known since the 1960s the nuclear propulsion is more efficient that chemical engines. It can burn for longer time periods at higher levels, thus making it possible to get to other planets more quickly, in some cases bypassing the need to depend on orbital mechanics.

The problem however has been political. Getting these nuclear engines into orbit has been too much of a political hot potato. The fear of such engines and radioactivity, largely irrational, has made it impossible to get them built. NASA is now trying again.

Japan’s government wants its private sector to do all its future space station work, not its space agency JAXA

9:05 am

In a major shift of power away from its government, the Japanese science and technology ministry is presently drafting a policy that would have that country’s private sector lead all work that Japan does on any of the future commercial private space stations being built, not its space agency JAXA as has been done now for decades.

The draft policy specifies how Japan will be involved with the next space station. According to the draft, “the private sector will have such responsibilities as managing [the new space station], and JAXA will support its use.”

JAXA is currently responsible to the management and maintenance of the ISS and serves as the point of contact for its commercial use. However, the government will select a Japanese private-sector company to be the point of contact for the next space station. When JAXA, research institutes or other companies plan to use the ISS, they will have to contact the next station’s point of contact.

While Japan wants to have one of its own modules on one of the commercial stations, as it presently has on ISS, it appears the government does not want JAXA to lead this project. Instead, it wants Japan’s private sector to run the show by working out its own deals with the private commercial stations. At present the Japanese company Mitsui is partnering with Axiom on its station, so this is likely the first station where a deal could be worked out.

It seems that Japan is trying to poke its private sector out of its doldrums. Right now that sector seems unable to take any action on its own. It sits and waits for guidance from the government before acting, and even then acts timidly, waiting to see if the government approves of each step. What the Japanese government now wants instead is some independent action, not linked to government policy.
