SLIM landed on the Moon softly, but upside down!

9:41 am

SLIM upside down

We now know why SLIM’s solar panel was not facing the Sun after the Japanese lunar lander touched down. When it was only 10 to 15 feet above the ground, preparing to land, one of its two descent engines failed, causing the spacecraft to tumble as it softly touched down. As a result, it landed softly, but upside down, thus putting the panel on its west side instead of its east side as planned.

The image to the right, cropped to post here, was taken by one of the two tiny rovers released by SLIM just prior to landing. It shows SLIM upside down, but essentially undamaged.

The lander however still apparently achieved its primary goal, landing within a small zone only 300 feet across, or 100 meters.

Analysis of the data acquired before shutting down the power confirmed that SLIM had reached the Moon’s surface approximately 55m east (180 feet) of the original target landing site. The positional accuracy before the commencement of the obstacle avoidance maneuver (at around a 50m altitude) which indicates the pinpoint landing performance, was evaluated to be at approximately 10m or less, possibly about 3 – 4m.

…Under these circumstances, the SLIM onboard software autonomously identifies the anomaly, and while controlling the horizontal position as much as possible, SLIM continued the descent with the other engine and moved gradually towards the east. The descent velocity at the time of contact with the ground was approximately 1.4 m/s or less, which was below the design range., but conditions such as the lateral velocity and attitude were outside the design range, and this is thought to have resulted in a different attitude than planned.

In other words, when that engine failed, SLIM was only about 10 to 30 feet from its pinpoint landing target, but then drifted eastward as its dropped those last few feet because of the unbalanced engine burn caused by only one engine.

That the spacecraft is still operating and can communicate with Earth, even though it is upside down, is remarkable. Moreover, SLIM did achieve its main goals quite successfully. It landed within its tight target zone, it released two mini-rovers which operated successfully, and has been able to send its own pictures back to Earth. It was not able however to test its crushable landing legs, as they remain in the air.

Six questions too many Democrats refuse to answer

1:26 pm

The Democratic Party: What does it really believe in?
The Democratic Party: What does it really believe in?

Today at the Washington Examiner journalist Elizabeth Stauffer has written a fine essay describing in general terms the inability of Democrats to discuss the issues today with any rationality.

The Democrats have settled upon their 2024 campaign message: “Former President Donald Trump poses a threat to democracy and must be stopped. He has openly admitted he will become a dictator on day one.”

Liberals make these statements about Trump and so-called MAGA Republican “extremists” because they know if they are repeated enough, they will stick. And they’re right. No evidence is required because the Democrats know they will never be called upon to support their claims by their comrades.

When questioned by conservatives, however, they simply hold fast to their lies.

Democrat Congressman Dean Phillips (D-Minnesota) — who is also running for the Democratic Party nonimation for President and got 21% of the vote in New Hampshire yesterday — put it more bluntly on January 22, 2024 on CNN:

“My party is completely delusional right now.”

Stauffer then lists six questions that every Democrat should be repeatedly challenged to answer, as follows:

Cool image time! The picture above, cropped and enhanced to post here, was taken on January 22, 2024 by the high resolution camera on the Mars rover Curiosity.

The photo gives us a fine example of the many very strange and delicate formations seen on Martian rocks and boulders as it slowly weaves its way up Mount Sharp, inside the slot canyon Gediz Vallis. On Earth such thin flakes like these are generally only seen inside caves, where there is almost no life to disturb their development and the natural conditions are as benign as well. On Mars, the only thing that can disturb this rock is the wind, and though over time it can erode things the thin atmosphere allows such flakes to form, aided by the gravity about 39% that of Earth’s.

The photo to the right, cropped, reduced, and sharpened to post here, was taken the same day by the rover’s left navigation camera, and illustrates the overall rocky nature of all of the terrain surrounding Curiosity. It looks to the southeast, at the base of nearby 400-foot-high Kukenan.

For a map showing Curiosity’s location (as well as another weird Martian rock, see my prevous post on January 17, 2024, A rock tadpole on Mars.

Europe signs up four rocket startups to provide it launch services

10:09 am

Capitalism in space: The European Space Agency (ESA) and the European Commission have jointly signed four rocket startups to contracts for eventually providing these government agencies a competitive commercial rocket industry capable of launching its payloads into space.

Each of the companies will receive a “frame” contract as part of the initiative, allowing them to compete for task orders for launching specific missions. Officials did not disclose the anticipated value of those contracts, or how many launch companies competed to participate in the program.

Four of the companies selected for the Flight Ticket Initiative are startups working on small launch vehicles: Isar Aerospace, Orbex, PLD Space and Rocket Factory Augsburg. None of them have yet conducted an orbital launch but expect to do so within the next two years.

Arianespace, ESA’s launch company that previously had a monopoly on launches, also received a frame contract, but it apparently must now compete for future contracts with these startups.

Europe had attempted to compete with SpaceX by once again using Arianespace and its big space contractors to build the Ariane-6 rocket. That project however is years behind schedule, and has resulted in an expendable rocket that is too expensive. Europe has thus been forced to buy launches from SpaceX.

This new arrangement essentialy means that Europe has adopted the recommendations I made in my 2017 policy paper, Capitalism in Space, available here [pdf]. Rather than design, build, and own its rockets, Europe will instead become a customer like anyone else, buying products developed and owned by private and competing European rocket companies.

Of the startup companies listed above, two (Isar and Rocket Factory) are German, one (Orbex) is British, and one is Spanish (PLD). Thus, this arrangement also spreads the wealth throughout Europe.

Unless outside events change things (such as war or economic collapse), this decision is likely to result in a renaissance in Europe’s launch industry comparable to what is happening now in the U.S. and India. If so, the future for the exploration and settlement of the solar system looks bright indeed.

Florida legislature considering bills to expand territory of its commerical Florida spaceport

9:51 am

Four bills under consideration in Florida’s legislature are proposing to expand the territory controlled by Space Florida, the state agency that runs the state’s commerical spaceport.

HB 577 and SB 968 seek to expand Florida’s spaceport system territory to include Tyndall Air Force Base and Homestead Air Reserve Base. Space Florida says the land owners still have authority over what projects or improvements can be made.

CS/HM 143 and SB 370 seeks to add seaports as a qualified tax-exempt category of private activity bonds. Space Florida is urging Congress to take action, as receiving the tax exemption is not something the state alone can change.

The bills specifically refer to property that the state owns within these federal bases or recently given back to the state. Overall however these bases remain federal facilities. It thus appears the bills are mostly designed to pressure Congress to act to give Space Florida more control.

The supporters of the bills cite the need for this expansion due to the spectacular increase in commercial launches in Florida, which set a record last year and is expected to do the same each year for the foreseeable future. The irony is that when the space shuttle’s retirement was announced in 2004, Florida officials thought this would be an end to the state’s space operations. Instead, private enterprise since then has resulted in a growth far greater than anything NASA ever provided.

First two stages of New Glenn assembled for the first time

9:35 am

After years of delays, Blue Origin announced yesterday that it has finally joined the first and second stages of its orbital New Glenn rocket, in preparation for its planned first launch later this year.

The stages remain horizontal inside Blue Origin’s assembly facility at Cape Canaveral, where engineers continue to check them out.

New Glenn’s launch was originally supposed to be in 2020. Problems with its first stage BE-4 engine put it (as well as ULA’s Vulcan rocket) four years behind schedule. The evidence now suggests that those problems were badly acerbated by the poor leadership of Bob Smith, Blue Origin’s CEO from 2017 to 2023, who apparently refused to spend money on test engines and the additional hardware necessary to test the engine to figure out what was wrong. Smith also appeared to slow all other work down in numerous ways as well as antagonize many at the company, causing a lot of high level engineers over time to flee.

Almost to the day Smith left last year Blue Origin has appeared to come to life. If so, this bodes well for both its future as well as that of the entire American rocket industry. New Glenn is a very powerful rocket, capable of lifting 50 tons to low Earth orbit, making it comparable to SpaceX’s Falcon Heavy. Its first stage is also designed to be reuseable, landing on a drone ship like the Falcon 9. If successful it will thus be a very capable competitor to SpaceX.

The company is aiming for an August launch. Keep your fingers crossed.

Belgium signs the Artemis Accords

9:19 am

Belgium yesterday became the 34th nation to sign the American-led Artemis Accords, bi-laterial agreements initially conceived by the Trump administration as a way to get around the legal limitations on private property created by the Outer Space Treaty.

Based on the wording of Belgium’s press release, it appear however that this goal is slowly being watered down by the many nations who have signed:

Belgium’s signature of the Artemis Accords is part of its proactive participation in the work of the United Nations Committee on the Peaceful Uses of Outer Space (UNCOPUOS). As a party to the five United Nations treaties on outer space, Belgium, in close collaboration with other Member States, has launched several actions within the Committee over the past decade to promote the establishment of an international multilateral legal framework for equitable access to and benefits from space resources, as well as for the safe and sustainable use of these resources. [emphasis mine]

The highlighted word, “equitable”, is one of the key words in Critical Race Theory, and when translated into plain English means providing guaranteed benefits for those who feel oppressed, whether or not they deserve it. Note too Belgium’s effort here to get the United Nations involved. By outlawing any nation from claiming territory and establishing its legal framework, the Outer Space Treaty essentially gave that power to the UN. The accords were conceived as a political way of breaking that restriction, shifting power back to the nations who signed. By inserting the UN into the Artemis alliance Belgium is trying to shift power to the UN again. And it appears it is attempting to form its own alliance of the smaller nations within the accords for this purpose.

The full list of signatories to the Accords is as follows: Angola, Argentina, Australia, Bahrain, Belgium, Brazil, Bulgaria, Canada, Columbia, Czech Republic, Ecuador, France, Germany, Iceland, India, Israel, Italy, Japan, Luxembourg, Mexico, the Netherlands, New Zealand, Nigeria, Poland, Romania, Rwanda, Saudi Arabia, Singapore, South Korea, Spain, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.

The competing alliance of communist nations, led by China, includes only Russia, Venezuala, Pakistan, Belarus, Azerbaijan, and South Africa. That former deep Soviet bloc nations like Bulgaria and Romania, as well as previously very Marxist Angola, went with the west rather than China illustrates the international distrust of China and its authoritarian methods.

An ancient Martian river system now meandering ridges

Context camera mosaic of river system.

An ancient Martian river system
Click for original image.

Cool image time! The picture to the right, cropped and reduced to post here, was taken on August 27, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It was featured by MRO’s science team yesterday, in which Shane Byrne of the Lunar and Planetary Lab University of Arizona wrote the following:

River beds often get filled with gravel and the surrounding terrain is often built up of fine-grained mud from river overflows. The gravely river bottom and the fine-grained surroundings can lead to a strange phenomenon that geologists call inverted channels. After the river disappears, the fine-grained surroundings can be easily eroded away leaving the gravely river bed as a high-standing ridge.

These ridges show the location of the old river beds in Mars’ distant past. The angle at which the ridges join together indicate that these rivers flowed from top-right to bottom-left (i.e. southwest).

The picture above is a mosaic produced from the global survey taken by MRO’s lower resolution context camera. It gives us a fuller picture of this river system, with the rectangle showing the small area covered by the photo on the right. Overall this ancient and extinct river of ridges travels more than thirty miles downhill from the northeast to the southwest.
