Starship gets contract to deliver Lunar Outpost’s rover to Moon

11:10 am

Capitalism in space: The lunar lander version of SpaceX’s Starship has won a contract from the startup Lunar Outpost to deliver its manned rover to the Moon.

The Colorado company announced Nov. 21 that it signed an agreement for SpaceX to use Starship to transport the company’s Lunar Outpost Eagle rover to the moon. The companies did not disclose a schedule for the launch or other terms of the deal.

This announcement is less a new deal for SpaceX and more an effort to convince NASA to award Lunar Outpost the full contract to build the rover. In April 2024 Lunar Outpost was one of three companies chosen by NASA to receive initial development grants to design their proposed manned lunar rovers. NASA expects to award the full contract, worth potentially up to $4.6 billion, to one of these three companies later this year, after seeing their preliminary designs. It wants to choose two, but at present says budget limitations make that impossible.

ESA and JAXA sign agreement to increase cooperation and accelerate development of Ramses mission to Apophis

10:18 am

The new colonial movement: The European Space Agency (ESA) and Japan’s own space agency JAXA on November 20, 2024 signed a new cooperative agreement to increase their joint work on several missions, the most important of which is the proposed Ramses mission to the potentially dangerous asteroid Apophis during its 2029 close fly-by of Earth.

Two agencies agreed to accelerate to study potential cooperation for ESA’s Rapid Apophis Mission for Space Safety (RAMSES) which aims to explore the asteroid Apophis that will pass close to our planet on 13 April 2029, including but not limited to provision of thermal infrared imager and solar array wings as well as possible launch opportunities.

The two countries are already working together on two different planetary missions, the BepiColombo mission to Mercury and the Hera mission to the asteroid Dymorphos. Both are on their way to their targets. This new agreement solidifies the commitment of both to make sure Ramses is funded, built, and launched in the relatively short time left before that 2029 Earth fly-by. At the moment the ESA has still not officially funded it fully.

China’s plan to land astronauts on the Moon

9:31 am

Mengzhou as of 2023
Click for source.

The new colonial movement: China’s state-run press yesterday revealed the basic flight plan its space program will use to land astronauts on the Moon in 2030.

China’s first manned lunar mission will begin with the launch of the Lanyue lunar lander aboard the country’s new heavy carrier rocket [the Long March 10], and Lanyue will then await the subsequent arrival of the Mengzhou manned spacecraft in space. Mengzhou will be poised for its rendezvous with Lanyue in lunar orbit, at which time the astronauts will transfer into the lander.

The lander will then separate and descend to the moon’s surface. Upon the completion of their lunar exploration, the astronauts will return to lunar orbit in the lander’s ascent stage. This stage will involve re-docking with the spacecraft, and will mark the beginning of the astronauts’ journey back to Earth.

This plan is a variation of the Apollo approach, but rather than sending the ascent/descent capsule and lunar lander on the same rocket, China will launch them separately and have them rendezvous in lunar orbit.

Mengzhou is intended to be a larger and reusable replacement for the Shenzhou capsules China is presently using to transport its astronauts to and from its Tiangong-3 space station. Unlike Shenzhou, which appears to be an upgrade of Russia’s Soyuz capsules, Mengzhou instead appears more conelike, as shown by the mockup image to the right, first revealed in 2023.

The next two Vulcan launches for the Pentagon slip to 2025

9:14 am

Both the Space Force and ULA have now admitted that the next two Vulcan launches, which both had hoped to launch before the end of this year, have now been delayed until 2025, and that Vulcan remains uncertified as yet by the military for its launches.

The United Launch Alliance’s Vulcan will not be able to conduct two planned national security missions on its launch manifest for this year after delays with certifying the heavy-lift rocket. The comments came hours after a Space Force official cast doubt that the missions could be completed before the end of 2024.

ULA launched its second certification flight in October, roughly a month behind schedule, following a first flight in January that was nearly four years behind schedule. The Space Force is still assessing data from the October launch in partnership with ULA.

The military had said if ULA completed two Vulcan successful launches it would approve Vulcan for these launches. Though the second launch got its payload to its correct orbit, during launch the nozzle on one of its strap-on solid-fueled boosters fell off. Though officials keep saying they expect certification anyway, that certification has not happened. It appears right now that the military won’t do so until the investigation into the problem is completed and a fix is installed.

At the moment the only rocket company that can launch large payloads for the Pentagon is SpaceX. Though that company has not gouged the military in bidding (though it it could) this is not a good situation. The military wants options and redundancy, not simply to save money, but to give it flexibility. It needs ULA and Blue Origin to finally deliver their rockets.

If ordinary people don’t show up at those upcoming FAA Starship/Superheavy public meetings they WILL be screwed

Starship splashing down vertically
Starship splashing down vertically in the
Gulf of Mexico on November 19, 2024

Yesterday radio host Robert Pratt sent me a news story from a Texas newspaper, the Texas Tribune, which attempted quite surprisingly to capture fairly the local response to the most recent Starship/Superheavy test launch out of Boca Chica on November 19, 2024.

The reporter, Bernice Garcia, clearly made it a point to talk to a lot of people, especially those who came out to see the launch. As a result, she showed that in general, no matter what people felt about Donald Trump or Elon Musk, the local population was almost entirely in favor of SpaceX’s efforts there. For example:

Sanchez was slightly concerned about [the rocket’s sonic booms] but believed the benefits of jobs created by SpaceX was worth the risk. “They know what they’re doing,” Sanchez said.

But his favorable opinion of Musk’s company did not extend to Trump. A naturalized citizen who gained amnesty under the Reagan administration, Sanchez didn’t view Trump’s immigration policies as logistically sound. “If you throw those people out, who’s going to work?” Sanchez said. “You don’t see a white man laboring out in the sun. On the other hand, Mexicans, foreigners, people from other countries –– that’s why they come here, to work.”

While the story found locals with a whole range of opinions about Trump, both positive and negative, it only quoted one person who was hostile to SpaceX, and that quote and person tells us a great deal about the bankrupt nature of that opposition:

Gophers dropped near Mt St. Helens for one day cause a gigantic bloom of plant life 40 years later

12:02 pm

In 1982, two years after the Mt. St. Helens volcanic eruption, scientists decided to do an experiment: They dropped six gophers into one meter square enclosures near the eruption with the hope the animals’ digging for one day would bring good soil close enough to the surface to encourage the return of plant life.

The results forty-plus years later:

Six years after their trip, there were over 40,000 plants thriving where the gophers had gotten to work, while the surrounding land remained, for the most part, barren. Studying the area over 40 years later, the team found they had left one hell of a legacy. “Plots with historic gopher activity harbored more diverse bacterial and fungal communities than the surrounding old-growth forests,” the team explained. “We also found more diverse fungal communities in these long-term lupine gopher plots than in forests that were historically clearcut, prior to the 1980 eruption, nearby at Bear Meadow.”

“In the 1980s, we were just testing the short-term reaction,” Allen added. “Who would have predicted you could toss a gopher in for a day and see a residual effect 40 years later?”

You can read the published paper here. It appears the gophers’ action activated the microbiological life in the soil, which in turn made it easier for plant life to return.

The potential benefits of this research is gigantic, especially in areas that have been devastated by any number of natural and man made disasters.

ESA gives its big space rocket company, ArianeGroup, a big subsidy

10:29 am

On November 19, 2024 I noted that in awarding four new rocket startups development contracts worth a total of 44 million euros, the European Space Agency (ESA) had not given any of that grant money to its biggest and most established rocket company, ArianeGroup, which not only owns and builds the Ariane-6 rocket but also has a subsidiary called MaiaSpace that is developing its own smallsat partly reusable rocket, in direct competition with those four small startups.

The exclusion of ArianeGroup in that announcement suggested to me that ESA had decided ArianeGroup’s smalsat rocket subsidary could manage without any additional aid, since its owner is a well-financed big space contractor.

I was wrong. Today the ESA awarded ArianeGroup a much big pile of cash, totaling 230 million Euros, to further finance the development of a reusable demonstration rocket, dubbed Themis, that also uses ArianeGroup’s Prometheus rocket engine. The Themis hopper project has been under development since 2018 initially under the management of Arianespace, has seen many delays in that time, and is now three years behind schedule.

Because of these delays, ESA pulled it from Arianespace in 2022 and gave full control of the project to the builder, ArianeGroup. This new contract award appears to be cementing this new arrangement, and is in addition to previous awards for this project exceeding 224 million euros.

The award also apparently includes funds for ArianeGroup’s MaiaSpace smallsat rocket startup, though the exact amount has not been specified.

The bottom line is that ESA is still dumping lots of cash to its older big space companies. Despite its clear shift to promoting independent rocket startups instead of a single government-controlled commercial entity (Arianespace), it is still favoring the big space contractors like ArianeGroup it has used for decades under that old Soviet-style system.

It will be interesting to see how this unbalanced system plays out in the coming years. Europe might get a competitive rocket industry of many companies, but then it might not, considering its space agency is putting its thumb on the scale to favor the already-established players.

Musk: Starship will likely attempt a chopstick landing on the eighth test launch

9:57 am

UPDATE: The original post below is incorrect. I misread Musk’s tweet, not realizing he was refering exclusively to Starship when he wrote “ship.” He and his company now routinely use “ship” to refer to Starship and “booster” for Superheavy.

The real story behind this tweet is that SpaceX is working to attempt a chopstick catch of both Superheavy and Starship on the eighth test flight, after the as-yet unscheduled seventh flight. This means the eighth flight of Starship will be a full orbital flight, will use its Raptor engines to do a de-orbit burn to bring it back to Boca Chica, and that the company expects to have two launchpad towers ready to make the two catches.

Won’t that be an exciting event?

Original incorrect post:
———————————–
According to a tweet by Elon Musk on November 19, 2024, SpaceX will not attempt a chopstick landing of Superheavy on the seventh test orbital launch of Starship/Superheavy.

We will do one more ocean landing of the ship. If that goes well, then SpaceX will attempt to catch the ship with the tower.

According to an update on the SpaceX website, the decision to abort the chopstick landing during this week’s sixth test flight was made because of issues at the launch tower:

Following a nominal ascent and stage separation, the booster successfully transitioned to its boostback burn to begin the return to launch site. During this phase, automated health checks of critical hardware on the launch and catch tower triggered an abort of the catch attempt. The booster then executed a pre-planned divert maneuver, performing a landing burn and soft splashdown in the Gulf of Mexico.

At this moment SpaceX has not provided any additional information on what those issues at the tower were, and might never do so since this is proprietary information. Nonetheless, it could be that more work is necessary to make sure the tower is healthy after launch, which is why they won’t attempt a chopstick landing next time.

As for when that seventh test flight will occur, we as yet have no word. The timing is going to depend on many factors, including the need for upgrades, the final flight plan decision, any changes then required to SpaceX’s FAA launch license, and finally the impact the new Trump administration will have on that red tape.

Space Perspective wants to launch its balloon from the Middle East

9:49 am

Space Perspective's Neptune Capsule
Space Perspective’s Neptune balloon capsule

The high altitude balloon company Space Perspective is presently in discussions with a number of Middle Eastern nations to find a location from which tourists can take tourist flights on its Neptune balloon capsule.

The Florida-based company is spending time in the Gulf to evaluate opportunities and expects to select a location in the first quarter of 2025, Michael Savage, its chief executive, told The National on Wednesday on the sidelines of the Skift Global Forum East in Dubai.

“We have interest from the UAE and entities from Abu Dhabi have come to visit mission control more than once. And we have interest from Qatar and from Saudi Arabia,” he said. “Our customer base likes to vacation in and visit this region, this has become a global hub for high-net worth vacationing … and because this is a luxury experience, it’s ideal for us to be as close as possible to that demographic.”

This the same approach that another American balloon company, World View, proposed in 2022. Since then however that company has not announced any updates of the tourist version of its high altitude balloons, which it has mostly been using to provide reconnaissance data for the Pentagon.

A U.S. startup building a returnable capsule raised $44 million in investment capital

9:37 am

The new American company Inversion Space — which is developing an orbiting cargo capsule called Arc — has now raised $44 million in private investment capital.

The Los Angeles-based company announced Nov. 20 that it raised a Series A round led by Spark Capital and Adjacent, with participation from Lockheed Martin Ventures, Kindred Ventures and Y Combinator. The company has raised $54 million to date, with a $10 million seed round in 2021. It also won in September a Strategic Funding Increase (STRATFI) agreement with the Space Force’s SpaceWERX valued at $71 million, a combination of government and private funding to support work on reentry vehicles tailored for military customers.

Inversion will use the funds to further development of Arc, a reentry vehicle designed to provide what it called “precision delivery on-demand” from space to the Earth. The company is currently working on the design of Arc with a first flight planned for 2026.

The number of companies developing orbiting cargo capsules, either to provide supplies to the new space stations or to do manufacturing in orbit for return and sale on Earth, appears to be growing by leaps and bounds. First there was SpaceX’s Dragon, though the company has not yet flown any in-space manufacturing missions. Varda followed next, and has already flown and returned one capsule successfully. Sierra Nevada will follow next year with the first launch of its reusable Tenacity Dream Chaser mini-shuttle. Inversion will be the fourth.

In Europe there is The Exploration Company in France with its Nyx capsule, the German startup Atmos with its Phoenix capsule, and the Spanish startup PLD with its Lince capsule. There may be more.

All of these orbiting and returnable capsules have multiple profit opportunities, which explains why there has been a willingness of investors to provide them funds. They can either supply cargo to the four private stations presently under construction, or fly independent orbital missions where the capsule carries equipment to produce products of value that can only be manufactured in weightlessness.

The space agencies of India and Australia agree to cooperate in recovering Gaganyaan

9:23 am

India’s space agency ISRO yesterday announced that it has signed an agreement with the Australian Space Agency (ASA) to work together in doing ocean recovery of India’s Gagayaan manned capsule.

The IA [Implementation Agreement] enables the Australian authorities to work with Indian authorities to ensure support for search and rescue of crew and recovery of crew module as part of contingency planning for ascent phase aborts near Australian waters.

Apparently ISRO anticipates the possible need for capsule ocean recovery near Australia should there be a launch abort shortly after liftoff.

Russia and SpaceX complete launches

9:16 am

Both Russia and the American company SpaceX successfully completed launches this morning. First, Russia sent a new Progress freighter on its way to ISS, its Soyuz-2 rocket lifting off from the Baikonur spaceport in Kazakhstan. The cargo ship is planned to dock with ISS in two days.

Next SpaceX put another 24 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida. The first stage completed its 20th flight, landing on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

119 SpaceX
53 China
14 Russia
12 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 137 to 80, while SpaceX by itself leads the entire world, including American companies, 119 to 98.

French rocket startup wins multi-launch contract

9:03 am

Capitalism in space: The French rocket startup Latitude yesterday announced that it has gotten a multi-launch contract from the German startup Atmos Space Cargo, which is developing its own returnable cargo capsule.

In a deal announced at Space Tech Expo Europe here Nov. 19, Atmos will buy a minimum of five launches a year of Latitude’s Zephyr rocket between 2028 and 2032. Terms of the deal were not disclosed.

Each launch will place a Phoenix spacecraft into very low Earth orbit, or VLEO. The spacecraft are designed to accommodate payloads for microgravity research in fields like pharmaceuticals and manufacturing, returning them to Earth.

Both companies have raised private investment capital, with Latitude raising $30 million and Atmos $1.4 million. Both are part of the sudden burst of new independent space companies that have emerged in Europe in only the last three years, even as many new American space startups have fallen by the wayside due to technical problems and government red tape.

Major court decision could invalidate many federal environmental regulations

1:54 pm

In what could be a major legal ruling [pdf], a two-judge decision this week in the DC Circuit Court ruled that the White House Council on Environmental Quality (CEQ), which has for years imposed environmental rules on other federal agencies based on the National Environmental Policy Act (NEPA), does not have the statutory authority to do so, thus invalidating every regulation so imposed.

All three members of the three-judge panel agreed that the Agencies acted arbitrarily and capriciously in [in this particular case]. However, before reaching that conclusion, the majority analyzed whether the CEQ regulations the Agencies followed in adopting the plan were valid, an argument not raised by any of the parties. The majority held, sua sponte, that because there is no statute stating or suggesting that US Congress has empowered the CEQ to issue rules binding on other agencies, the CEQ has no lawful authority to promulgate such regulations.

…Although this decision does not explicitly vacate any action taken by the CEQ, it does establish a precedent that CEQ rules lack statutory authorization, and therefore that other agency actions taken under the CEQ framework are at risk of being vacated. If this decision is not overturned by the full appellate court sitting en banc or by the US Supreme Court, it has the potential to completely change the landscape of NEPA review.

The case is complicated, partly because the Byzantine nature of the federal bureaucracy and the many agencies involved. (It is almost as if these agencies created that complexity to confuse and protect themselves.)

The heart of the decision is that CEQ was apparently first created as an “advisory” body to help other federal agencies follow the intent of NEPA in their own rule-making, but instead soon became a “regulatory” body whose rulings other agencies were required to follow. As that authority was never given it by Congress, CEQ exceeded its authority by making its rulings mandatory.

This court decision will likely leave many agencies on their own in establishing environmental regulations, based on NEPA. However, even that regulatory ability faces limitations, based on the Supreme Court’s recent Chevron decision, which said that government agencies do not have right to promulgate new regulations that are not specifically described in congressional law.

In other words, Chevron says that the bureaucracy cannot make things up, based on its own vague opinions.

The trend of all these court rulings appears aimed at limiting the power of the federal bureaucracy. It will however take some time to determine how much that power is limited, as lawsuits begin to percolate through the courts. If there are lot of lawsuits (which does appear to be happening) we should therefore expect that power to be limited significanly.

Another cool hiking location on Mars

Overview map

Another cool hiking location on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on August 10, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

My reason to posting this I admit is selfish and tourist-oriented. This narrow ridge, about a mile long and about 300 to 600 feet high, appeals directly to my hiking passions. A trail along its length would provide any hiker some really spectactular views.

The scientists took the picture because of the geology. The white dot on the overview map above marks the location, a short channel dubbed Daga Vallis that connects two major canyons in the eastern part of Valles Marineris, the largest known canyon system in the solar system. This ridge and several nearby parallel ridges were apparently made of something, possibly lava, that was resistent to the theorized ancient catastrophic floods that scientists presently believe carved out these channels and canyons.

In the inset the dotted line indicates one possible hiking trail route that travels the full length of the ridge but then heads south to continue along the rim of a 1,200-foot-high cliff face. For future Martian colonists, I offer this site as a great place to set up a bed-and-breakfast, surrounded by many potential hikes of incredible stark beauty.

Rocket Lab announces first launch contract for its new Neutron rocket

9:55 am

Though the press release was lacking in many details, Rocket Lab yesterday announced the signing of its first launch contract for its new Neutron rocket, scheduled to make its first orbital test launch in 2025.

Under the contract, Rocket Lab will launch two dedicated missions on Neutron starting from mid-2026. The missions will launch from Rocket Lab Launch Complex 3 on Wallops Island, Virginia. The launch service agreement for these missions signifies the beginning of a productive collaboration that could see Neutron deploy the entire constellation.

The press release did not name the satellite constellation, or the company building it. Rocket Lab’s founder and CEO, Peter Beck, was quoted as follows: “Constellation companies and government satellite operators are desperate for a break in the launch monopoly.” [emphasis mine] That launch monopoly is clearly SpaceX, and Beck was positioning Rocket Lab with Neutron as the company to provide an alternative.

The announcement as well as the company’s third quarter report caused a 45% surge in its stock price.

The dim future of SLS indicated at space business symposium

9:37 am

At a symposium in DC yesterday, a panel of past managers — all of whom had been involved in previous government transitions at NASA — attempted to predict what the consequences will be for NASA with the new Trump administration.

Most of the opinions were pure guesses, some better than others. The real moment of truth came when the entire panel was asked to predict the future of SLS and Orion. The question was put forth by one of the panelists, Lori Garver, who had been NASA’s deputy administrator during the Obama administration, and seemed to have the best understanding of how much the arrival of Trump will likely shake things up significantly.

At one point in the discussion, she asked the panel if they thought the Space Launch System and Orion programs would continue in the next administration. None of the panelists raised their hands. [emphasis mine]

Several of these panelists were big supporters of SLS. Their lack of confidence in its future tells us that SLS and Orion no longer have strong political backing in Washington. Both stand on thin ice.

I predict both will be shut down within the next year, before the next Artemis flight, the first to be manned, to be replaced with a entirely different manned space exploratory program to the Moon and Mars. The decision will be a smart one, but tragically late in coming. SLS should have been dumped years ago. If it had, the U.S. effort to return to the Moon would have been better off, moving forward with a better plan years earlier. Instead, this late decision will once again delay any manned lunar missions for years more.

The change however will be good in the long run, because I expect the new program will be better designed, more efficient, cost less, and be able to do what SLS promised but could never deliver. And it will be based on what private enterprise can accomplish, not a government designed behemoth designed mostly as pork.

Firefly raises $175 million in new private investment capital

9:19 am

The rocket startup Firefly has now raised another $175 million of private investment capital, during a new round of funding, on top of another $300 million raised previously.

Firefly Aerospace has raised $175 million in a round led by a new investor to support production of launch vehicles and spacecraft with an increased focus on responsive space capabilities.

The company announced Nov. 12 it raised what it described as an oversubscribed Series D round led by RPM Ventures. Several other existing and new ventures also participated in the round, which values Firefly at more than $2 billion.

That valuation is an increase from the $1.5 billion the company reported in November 2023 when it closed the final tranche of a Series C round. The company did not disclose the size of that earlier round but said then it had raised about $300 million since February 2023.

It appears RPM likes how the company has focused on providing the military launch services, which can also be profitable for private satellite customers. This money will be used to help increase the production of Firefly’s Alpha rocket.

JPL to layoff 5% of its workforce, the third major layoff this year

9:10 am

JPL in California announced today a layoff of 325 workers, about 5% of its workforce, the third major layoff imposed this year.

The JPL press release indicates the layoffs are because of NASA budget cutbacks, but does not provide any specificity. The cause centers mostly around NASA’s decision to pause its Mars Sample Return project, which JPL was leading. From this report:

This is the third round of layoffs at JPL this year, a reduction spurred primarily by major budgetary cuts to the Mars Sample Return mission, which is managed by JPL. NASA directed $310 million this year to the effort to bring Mars rocks back to Earth, a steep drop from the $822.3 million it spent on the program the previous year.

In January, 100 on-site contractors at JPL were let go after NASA instructed the lab to reduce spending in anticipation of a much tighter budget. In February, the lab laid off 530 employees — approximately 8% of its workforce — and another 40 contractors.

It increasingly appears that JPL’s place in the redesigned mission could be significantly reduced.

The press release also makes it sound like these cutbacks are the end of the world. As JPL has mostly functioned for decades as a private institution attached to NASA almost like a government agency, no one there ever expects to get laid off. In the real world however layoffs such as this happen all the time, especially when a company fails to deliver. JPL in recent years has had budget and management problems, epitomized by the problems now seen with that sample return mission, so it should not be surprised by these cutbacks from NASA.

Cargo Dragon docked to ISS boosts station

8:59 am

For the first time a cargo Dragon capsule used its Draco attitude thrusters to test their ability to adjust or raise ISS’s orbit.

NASA and SpaceX monitored operations as the company’s Dragon spacecraft performed its first demonstration of reboost capabilities for the International Space Station at 12:50 p.m. EST on Friday. The spacecraft’s Draco thrusters adjusted the station’s orbit through a reboost of altitude by 7/100 of a mile at apogee and 7/10 of a mile at perigee, lasting approximately 12 minutes and 30 seconds.

This posting is late because of my Grand Canyon trip, but I’m posting this now to make sure it is on the webpage. The goal of the test was to prove another American method for adjusting ISS’s orbit, in order to replace the Russian Progress capsules which now do the job. This test proved Dragon’s thrusters can be used for small orbital adjustments, but whether it can do major orbital corrections remains unclear. A previous test using Cygnus had already showed it could do the job.

Polaris completes first inflight ignition of its aerospike engine

12:08 am

In what appears to be a first, Polaris Spaceplane on October 29, 2024 successfully completed the first ever inflight ignition of an aerospike engine, using its Mira-2 unmanned engineering prototype.

Later in the day on 29 October, MIRA II took off from Peenemünde Airport on the coast of the Baltic Sea with a takeoff mass of 229 kilograms, which represented a reduced propellant load. The vehicle flew to the ignition point over the Baltic Sea, approximately 3 kilometres away from the ground station, and once there, completed a short three-second burn of its AS-1 aerospike engine. During the short burn, MIRA II experienced an acceleration of 4 m/s².

According to the company, the engine operated at a reduced chamber pressure during the three-second burn, resulting in a fuel-rich combustion.

There have been several attempts in the past to develop the aerospike engine, none of which ever completed any test flights, as far as I am aware. The concept is that the thrust is released in a string of openings, with only one wall forming the nozzle shape and the atmosphere used to complete the nozzle on the other side. As the atmospheric density changes the nozzle shape thus changes its shape, producing the most efficient thrust throughout the engine’s entire flight.

More test flights will be required before the company will be able to begin work on its full scale Aurora spaceplane.

SpaceX launches twice today from different Florida launchpads

9:01 pm

SpaceX today successfully launched twice. First a Falcon 9 rocket lifted off from Kennedy Space Center in Florida, placing a South Korean communications satellite in geosynchronous orbit. The first stage completed its 23rd flight, landing back at Cape Canaveral.

Then, several hours later, a Falcon 9 lifted off from Cape Canaveral, placing 24 Starlink satellites in orbit. The first stage completed its 12th flight, landing on a drone ship in the Atlantic.

UPDATE: China also completed a launch earlier today, its Lijian-1 rocket lifting off from its “commercial” launchpad at its Jiuquan spaceport in northwest China. No word on where the lower stages crashed inside China. The payload was fifteen satellites, including a remote-sensing satellite for Oman.

The leaders in the 2024 launch race:

112 SpaceX
51 China
13 Russia
12 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 130 to 76, while SpaceX by itself leads the entire world, including American companies, 112 to 94.

A defunct satellite is now in an unexpected orbit, and no one knows how it got there

3:56 pm

Skynet-1A, a British satellite launched in 1969 and out of commission since the 1970s, has now been found in an unexpected location in geosynchronous orbit, and no one knows how it got there.

Launched in 1969, just a few months after humans first set foot on the Moon, Skynet-1A was put high above Africa’s east coast to relay communications for British forces. When the spacecraft ceased working a few years later, gravity might have been expected to pull it even further to the east, out over the Indian Ocean.

But today, curiously, Skynet-1A is actually half a planet away, in a position 22,369 miles (36,000km) above the Americas. Orbital mechanics mean it’s unlikely the half-tonne military spacecraft simply drifted to its current location. Almost certainly, it was commanded to fire its thrusters in the mid-1970s to take it westwards. The question is who that was and with what authority and purpose?

The article attempts to suggest the orbit change was done for some nefarious purpose, but the most likely explanation is that at some point the British engineers who operated it ordered the required engine burns, but the records of that work are now lost.

Though the present location poses some problems for other geosynchronous satellites, Skynet-1A also now offers a great opportunity for a mission demonstrating a way to clean up junk in these orbits.

China launches four remote-sensing satellites

China today successfully launched four new remote-sensing satellites, its Long March 2C rocket lifting off from its Jiuquan spaceport in northwest China.
