Firefly signs deal to launch its Alpha rocket from Esrange spaceport in Sweden

Proposed spaceports surrounding Norwegian Sea

Firefly has now signed a deal to launch its Alpha rocket in 2026 from the Esrange spaceport in Sweden, becoming that spaceport’s second orbital customer.

Esrange is not really a new spaceport. It was originally built in the 1960s and was used for decades for suborbital test launches, much like Wallops Island in the U.S. In January 2023 it upgraded one launchpad to allow commercial orbital launches, and in May 2024, signed a launch deal with a new rocket startup from South Korea named Perigee.

This new contract with Firefly is a bigger deal, because Firefly has already launched several times, and is more established.

These developments indicate as well the cost of red tape in the United Kingdom. The map to the right shows the spaceports competing for business in Europe. The two UK spaceports (Saxaford and Sutherland) began construction years before Esrange decided to upgrade, but both are now losing business to Sweden because regulatory delays at the Civil Aviation Authority in the UK has delayed all launches there for years.

ULA replaces Sierra’s mini-shuttle with dummy payload to launch Vulcan in September

9:28 am

Because of continuing delays in preparing Sierra Space’s Tenacity Dream Chaser mini-shuttle for launch, ULA has been forced to remove it from the second launch of Vulcan in order to proceed with the launch in September as planned.

ULA needs to launch Vulcan for the second time and as soon as possible in order to get approval from the Pentagon to do military launches. The delays in getting Tenacity ready for launch has already impacted that schedule, as ULA had originally hoped to launch Vulcan on its second flight — with Tenacity as the payload — several months ago. Further delays beyond September would seriously damage not only ULA’s bottom line, but the military’s own needs. It is all for these reasons that ULA has now set up a new review team to force this schedule forward, likely under pressure from the Pentagon.

Sierra Space meanwhile says that Tenacity is still on track to be ready to launch before the end of the year, but it is unclear what rocket will carry it. ULA will likely offer another Vulcan rocket for the purpose, but to do so it will probably have to delay some other payload, and it is certain it will not do that to any upcoming military launches. Based on the announced launch schedule, it does not look like this launch can occur on a ULA rocket in 2024. ULA says it hopes to launch at least 20 times in 2025, so one of those launches will likely carry Tenacity.

SpaceX launches 23 Starlink satellites, using a first stage for the 22nd time

9:08 am

SpaceX early this morning launched another 23 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral and using a first stage on its record-setting 22nd flight.

That stage successfully landed on a drone ship in the Atlantic. The flight was so routinely boring for the launch crew that the flight director felt no need to even bother having anyone do a T-10 second countdown at launch.

The leaders in the 2024 launch race:

68 SpaceX
28 China
8 Russia
8 Rocket Lab

American private enterprise now leads the world combined in successful launches, 79 to 42, while SpaceX by itself still leads the entire world, including other American companies, 68 to 53.

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 founder of the Mars Society.

An island of hundreds of scour pits in Mars’ largest volcanic ash field

An island of scour pits
Click for original image.

Cool image time! The picture to the left, cropped, reduced, and sharpened to post here, was taken on April 25, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

It shows what the science team labels a “scour pit island,” an area about 13 miles long and 3.5 miles wide where the ground is covered by these pits.

Your eye may play tricks on you, reversing the elevations. These are all pits, with most having a central peak or ridgeline. To help, note that the sunlight is coming from the west. The arrow on the center left of the picture sits on a plateau above these pits.

According to this paper [pdf], the pits are slowly dug out by the wind coming from the southeast blowing to the northwest, as indicated by the arrows. The central peaks or ridges are thought to be a hint of the original topography, with the wind only able to pull ash from the terrain around these peaks.

Arianespace calls for Europe to require all European space payloads use European rockets

9:57 am

Arianespace, whose many-decade-long European launch monopoly is presently threatened by a wave of new rocket startups and an effort by European governments to created a competitive launch industry of many companies, has now urged Europe to require that all European space payloads use European rockets.

Arianespace head of public affairs Charlotte Lang has advocated for legislation that would require European missions to be launched aboard European rockets. Lang made the comments during the “Ensuring Long Term Autonomous Access to Space for Europe” panel on the first day of The European Space Forum conference. “The EU should enforce the principle of European launcher preference,” said Lang.

In a follow-up statement, Arianespace reiterated “the need for the EU to legislate that European missions are launched from European territory using launchers and technology manufactured in Europe by European providers.” The company identified the European Union’s planned IRIS² constellation as the “perfect opportunity to advance this initiative.”

Arianespace is like Blue Origin. It can’t get its rockets built and flying at a competitive price, so instead it advocates lawfare to limit competition in order to give it a favored position when it bids on future launch contracts.

In the case of Europe, I think this Arianespace effort will generally fall on deaf ears. The trend among numerous European governments (Germany, France, Italy) is to encourage new rocket companies to compete with Arianespace, in order to create options. These governments will of course wish to favor these new European rocket companies with any contract awards, but they will also not want to tie their hands with the kind of legislation Arianespace proposes. They all discovered in the past two years what could happen if they do that, when Arianespace failed to get Ariane-6 launched on time, and Europe ended up with no launch capabilities. During that time period they still had the option to use other non-European options (such as SpaceX). Having that flexibility in the future makes great sense.

Blue Origin to FAA: Limit future SpaceX Starship launches at Cape Canaveral

9:38 am

Blue Origin has once again decided to use lawfare against SpaceX rather than actually build rockets that are competitive. As part of the process by the FAA to do a new Environmental Impact Statement on SpaceX’s plans for Starship/Superheavy launches at Cape Canaveral, Blue Origin last week submitted its own comment asking the FAA to cap the launches of its competitor, citing environment concerns.

The company recommends the following mitigation method for SpaceX’s Starship launches, prior to the company being issued a Vehicle Operator License:

“Capping the rate of Ss-SH launch, landing, and other operations, including but not limited to test firings, transport operations, and fueling, to a number that has a minimal impact on the local environment, locally operating personnel, and the local community, in consideration of all risks and impacts, including but not limited to anomaly risks, air toxin and hazardous materials dispersion, road closures, and heat and noise generation.”

Along with requesting a max number of Starship launches at the site, Blue Origin argues that the government increase launch infrastructure that opens other launchpads to nearby lessees when roads are forced to be closed for SpaceX launches. The filing also notes that SpaceX has already received environmental testing at its Starbase site in Boca Chica, Texas.

You can read Blue Origin’s full comment here [pdf]. Essentially, Blue Origin is attempting to use this new impact statement to have the federal government damage or destroy its competition.

Musk’s response was a two word tweet: “Sue Origin.”

It is very clear that Jeff Bezos’s company is poorly focused. In the last decade it has built almost nothing, while spending a lot of time filing lawsuits against its competition. This action is simply another example.

Worse, Blue Origin’s comment will provide ammunition for the continuing Biden administration lawfare against Musk and SpaceX, making it difficult for the FAA to approve the impact statement as requested by SpaceX. If so, the development and operational use of Starship/Superheavy will be seriously threatened.

Collins reportedly in the process of canceling its NASA spacesuit contract

9:19 am

As if NASA didn’t have enough spacesuit problems, with a ISS spacewalk this week canceled because one of the NASA-built suits on the station began leaking water again, Collins Aerospace, one of the two companies that won contracts to build new spacesuits, is now in negotiations to end that contract.

But Collins’ role in the program has been bumpy and development has fallen behind schedule, and the company has been in talks with NASA officials on how to wind down its role in the program, the two people said. “After a thorough evaluation, Collins Aerospace and NASA mutually agreed to descope Exploration Extravehicular Activity Services (xEVAS) task orders,” a Collins spokeswoman said in a statement, referring to the spacesuit contract.

If this story is confirmed, it means at present only Axiom is building new spacesuits that can either be used on ISS or on future Artemis missions to the Moon and Gateway. Whether NASA will put out the Collins contract for bid again is unknown. In its original cargo capsule contracts early in the 2010s, one company failed to raise sufficient funds to build its capsule, so NASA cancelled it and awarded Orbital Sciences and its Antares rocket and Cygnus capsule the deal.

If the contract is put out for new bidding, SpaceX would be in a very strong position to win, as its own internally financed spacewalk spacesuits are about to get their first flight test on Jared Isaacman’s Polaris Dawn mission on the Resilience Dragon capsule later this summer.

The failure of Collins here is disturbing, and might be an indicator of an overall loss in American engineering capabilities. Once a challenge like this would have posed no problem for any American aerospace company. Now such tasks are increasingly difficult and unachievable.

French rocket startup wins $16 million grant from French government

9:01 am

The French rocket startup Latitude has been awarded a $16 million grant from French government for development work on its proposed two-stage Zephyr orbital rocket, which is targeting 2025 for its first test launch.

Nor is this grant the only money the company has raised.

In January, Latitude announced that it had closed its Series B funding round, raising $30 million. In March, the company was one of four companies selected to receive a share of €400 million [$427 million] in subsidies from the French government. This funding is, however, only fully unlocked when the company completes its inaugural flight of Zephyr.

Though Latitude has obtained some private investment capital, it appears it is mostly relying on government funds. Under these conditions, it is unclear whether the rocket startup will be able to compete not only with the other new European rocket startups but with the rest of the world. Government funding is usually not well tied with profit or cost efficiency, and thus the company will have less incentive to develop a competitive rocket.

More garbage science about wildfires and global warming from Nature

12:31 pm

Nature: the science journal that no longer does real science
The science journal which no longer
understands how real science is done

The once highly respected science journal Nature continues its descent into propaganda and bad science, all because it bows unskeptically before the altar of global warming and leftist science fantasies.

Today’s example is an article this week entitled “You’re not imagining it: extreme wildfires are now more common,” describing a new Nature paper that attempted to use satellite data to prove that the intensity of wildfires has increased in the past two decades.

For the current study, published in Nature Ecology and Evolution on 24 June, Cunningham and his colleagues scoured global satellite data for fire activity. They used infrared records to measure the energy intensity of nearly 31 million daily fire events over two decades, focusing on the most extreme ones — roughly 2,900 events. The researchers calculated that there was a 2.2-fold increase in the frequency of extreme events globally in 2003–23, and a 2.3-fold boost in the average intensity of the top 20 most intense fires each year.

We’re all gonna die! As is usual for these crap climate-related studies, the entire goal is to drum up some manufactured new crisis that justifies the claim that the climate is warming. This study is no different, as the article eagerly notes:

Although the study doesn’t directly connect the fire trend to global warming, Cunningham [the study’s lead author] says “there’s almost certainly a significant signal of climate change”. Research has shown that rising temperatures are drying out ecosystems — such as coniferous forests — that are naturally prone to fire. This provides fuel that can boost the fires’ size and longevity. The latest study also found that the energy intensity of the fires increased faster during the night-time over the past two decades than during the daytime, which aligns with evidence4 that rising night-time temperatures are contributing to fire risk.

Not surprisingly, the New York Times immediately jumped on the bandwagon with its own article that accepts the conclusions of this research with utter naivety.

What junk. First, Cunningham fails to note this minor fact mentioned in the abstract of his own paper:

Airbus forced to write off almost a billion dollars

9:42 am

Even though the problems that Boeing has been driving its customers to Airbus, Airbus yesterday revealed that its own business outlook is presently suffering, forcing it to write off $965 million.

Yielding to growing scepticism among suppliers over its plans for jet output, Airbus lowered its widely watched forecast for deliveries this year to around 770 jets from around 800. It also tempered plans to raise output of its best-selling A320neo family, by delaying the date at which it expects to reach a record production speed of 75 jets a month to 2027 from 2026. That compares with an estimated 50 jets a month now.

As a result of the lower delivery forecasts, which imply annual growth of 5% instead of 9%, Airbus lowered its main financial targets for 2024. It now expects underlying operating income of around 5.5 billion euros, instead of a range of 6.5 billion to 7.0 billion, and free cashflow of 3.5 billion instead of 4.0 billion.

The article focuses on Airbus’s engine supply issues that are restricting its ability to build jets. It makes no mention of the company’s joint partnership with Safran to build the Ariane-6 rocket, which has failed to garner the business predicted, even as it is about to make its inaugural launch on July 9th. Though peripheral to the airplane issues described, it is certainly a factor in these financial issues.

Scientists surprised by new Webb data of the upper layers of Jupiter’s Great Red Spot

9:33 am

Jupiter's Great Red Spot, as seen in infrared
Click for original image.

The uncertainty of science: Using the Webb Space Telescope, scientists have obtained infrared data of the upper layers of Jupiter’s Great Red Spot, revealing that it is far more complicated that predicted by researchers.

The upper atmosphere of Jupiter is the interface between the planet’s magnetic field and the underlying atmosphere. Here, the bright and vibrant displays of northern and southern lights can be seen, which are fuelled by the volcanic material ejected from Jupiter’s moon Io. However, closer to the equator, the structure of the planet’s upper atmosphere is influenced by incoming sunlight. Because Jupiter receives only 4% of the sunlight that is received on Earth, astronomers predicted this region to be homogeneous in nature.

The Great Red Spot of Jupiter was observed by Webb’s Near-InfraRed Spectrograph (NIRSpec) in July 2022, using the instrument’s Integral Field Unit capabilities. The team’s Early Release Science observations sought to investigate if this region was in fact dull, and the region above the iconic Great Red Spot was targeted for Webb’s observations. The team was surprised to discover that the upper atmosphere hosts a variety of intricate structures, including dark arcs and bright spots, across the entire field of view.

You can read the published research paper here. The image to the right is figure 4 from that paper, with each panel showing different infrared wavelengths indicated by the different colors, and thus the complex structures and physical properties.

Firefly to launch from Wallops instead of Cape Canaveral

9:18 am

The rocket startup Firefly announced yesterday that it has decided to change its east coast launch site for its Alpha rocket from Cape Canaveral in Florida to Wallops Island in Virginia, using the same pad there that Northrop Grumman’s Antares rocket uses.

The company said that it would use Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) on Wallops Island for Alpha launches, starting as soon as 2025. The launch pad, built for the Antares rocket, will continue to be used for the revised Antares 330 Northrop Grumman is developing in collaboration with Firefly as well as the larger Medium Launch Vehicle (MLV) the companies are building.

The company says launching from Wallops, in addition to its existing pad at Vandenberg Space Force Base in California, will allow it to serve more customers. Wallops can support launches to lower inclination orbits than feasible from Vandenberg, which is best suited for sun-synchronous and other high-inclination orbits.

Because the revised Antares rocket will use a first stage built by Firefly (replacing a Ukrainian first stage no longer available due to Russia’s invasion), this change appears to make a great deal of sense. The revised pad will likely use comparable systems between both Antares and Alpha.

Chang’e-6 brings back the first lunar samples from Moon’s far side

9:10 am

According to China’s state-run press, the sample return capsule of its Chang’e-6 lunar mission successfully landed today in the inner Mongolia region of China, bringing back the first lunar samples from Moon’s far side.

Under ground control, the returner separated from the orbiter approximately 5,000 km above the South Atlantic. The capsule entered the Earth’s atmosphere at about 1:41 p.m. at an altitude of about 120 km and a speed of nearly 11.2 km per second. After aerodynamic deceleration, it skipped out of the atmosphere and then began to glide downwards, before re-entering the atmosphere and decelerating for a second time.
At around 10 km above the ground, a parachute opened, and the returner later landed precisely and smoothly in the predetermined area, where it was recovered by a search team.

The returner is set to be airlifted to Beijing for opening, and the lunar samples will be transferred to a team of scientists for subsequent storage, analysis and study, said the CNSA. [emphasis mine]

The highlighted sentence is important. China has now successfully flown this atmospheric skip maneuver twice on returning from the Moon. Though both missions were unmanned, the technical knowledge gained from these flights is critical for their plans to send astronauts to the Moon in the next few years.

I have embedded China’s broadcast of the landing below. The sample capsule will now be carefully opened and the samples distributed first to Chinese scientists and later to China’s various partners in its lunar base project. The samples themselves came from a small mare region on the edge of Apollo Crater inside South Aitken Basin, one of the largest impact basins on the Moon. It is thus hoped that the samples were excavated from deep within the Moon during the impact, and will provide new data on the Moon’s make-up and history.

Reparations: Taking money from people who never owned slaves and giving it to people who never were slaves

12:48 pm

Harvard: where you get can get a shoddy education centered on hate and bigotry
Harvard: where you can spend a lot of money
getting a shoddy education teaching hate and bigotry

The effort to justify the new fad of forcing all Americans today to pay blacks reparations for the evil of slavery that was eliminated a century and a half ago at the cost of more than 600K lives continues. A recent published study by two “Didn’t Earn It” (DEI) academic elites at the Harvard Kennedy School attempts to justify the distribution of reparations now by claiming that the U.S. has a long history of paying out money to harmed individuals. From the paper’s abstract:

[T]he United States has a long-standing social norm that if an individual or community has suffered a harm, it is considered right for the federal government to provide some measure of what we term “reparatory compensation.” In discussing this norm and its implications for Black American reparations, we first describe the scale, categories, and interlocking and compounding effects of discriminatory harms by introducing a taxonomy of illustrative racial harms from slavery to the present. We then reveal how the social norm, precedent, and federal programs operate to provide victims with reparatory compensation, reviewing federal programs that offer compensation, such as environmental disasters, market failures, and vaccine injuries. We conclude that the government already has the norm, precedent, expertise, and resources to provide reparations to Black Americans. [emphasis mine]

The highlighted word is key to understanding the fundamental intellectual dishonesty of these incompetent Harvard academics. In their paper they use numerous examples of cases where the government has provided compensation to actual individuals — such as veterans, individuals harmed by radiation from nuclear tests, and those who lost their pensions due to bankruptcy or mismanagement of their pension funds — and then claim this proves paying reparations to the community of blacks, based merely on their race and the past existence of slavery, is within traditional American jurisprudence.

This is all a lie. » Read more

Are Chang’e-6’s lunar samples on the way back to Earth?

9:30 am

In Friday’s June 21, 2024 quick links, changes to lunar orbit of China’s Chang’e-6 sample return spacecraft were detected by ham operators. As I noted, “It isn’t clear whether this was the previous orbit adjustment, a new one, or the burn that would send the sample return capsule back to Earth.”

According to Space News today, the spacecraft with the samples is on its way back to Earth, based on additional information detected by amateurs. China however has released no information on the status of the spacecraft.

Upon return to Earth, the reentry capsule is expected to touch down at Siziwang Banner, Inner Mongolia during an half-an-hour long window opening at 1:41 a.m. Eastern (0541 UTC) June 25. The information is according to airspace closure notices. CNSA has not openly published timings of mission events in advance.

Earlier reports (which I can’t find now) had said the return was tentatively scheduled for June 25, 2024, so this Space News report makes sense. The lack of information from China is par for the course.

France’s CNES space agency begins work adapting commercial launchpad at French Guiana for specific startup rocket companies

9:15 am

Capitalism in space: France’s CNES space agency, which has taken back ownership of its French Guiana spaceport from Arianespace, has now begun adapting its new commercial launchpad there for a number of specific startup rocket companies.

In early 2021, the French space agency CNES announced plans to open up the Guiana Space Centre to commercial micro and mini-launch operators. The agency explained that it would be developing a multi-user launch pad on the grounds of the old Diamant launch complex. In July 2022, CNES announced that it had pre-selected Avio, HyImpulse, Isar Aerospace, MaiaSpace, PLD Space, Rocket Factory Augsburg, and Latitude to utilize the new launch complex.

During a media briefing following ESA’s 327th council meeting, Tolker-Nielsen explained that “general work” on the complex had already started and that work on “specific adaptations” was about to begin. These specific adaptations will be completed by the companies that will utilize the launch complex to ensure it fulfills the specific needs of their launch systems.

Of the seven rocket startups listed above, Tolker-Nielson said PLD was the ahead of the others in adapting the pad for its use, though no launch date is set. Avio meanwhile will likely not have to use this pad, as it owns the Vega family of rockets, which have already launched from French Guiana using another launchpad.

China’s successfully completes full 10K hop of 3-engine launch test rocket

8:57 am

China’s yesterday successfully completed a 10K hop lasting six minutes of 3-engine launch test small-scale rocket, lifting off from its Jiuquan spaceport in northwest China.

Developed by the Shanghai Academy of Spaceflight Technology, the carrier rocket features a 3.8-meter diameter rocket body, powered by three 70-tonne LOX/Methane engines and equipped with a full-size landing buffer system.

The rocket achieved vertical soft landing at a fixed point through take-off, ascent and variable-thrust descent. The test fully verified the rocket’s VTOL configuration, heavy-load landing buffer technology, reusable propulsion technology with high and strong variable thrust, and high-precision landing navigation and control technology.

I have embedded below a video that shows the take-off, parts of the flight, and landing. China hopes to fly a full scale orbital version, with a 4-meter diameter, in 2025.

Spacewalk on ISS canceled due to spacesuit issue

8:48 am

Two astronauts on ISS were forced today to abort their spacewalk soon after opening the hatch to go outside because a water issue in one suit.

This is the second time this spacewalk has been aborted. The first time, on June 13, 2024, was canceled due to an unspecified “spacesuit discomfort issue.”

This cancellation might cause a problem with the presently unscheduled return of Starliner, as its June 26, 2024 return was postponed to allow this spacewalk to take place without any schedule conflicts. Or it might simplify Starliner’s return, as the spacewalk will not happen due to spacesuit issues.

Note also that the American suits are old, and prone to these kinds of water leak issues. NASA started a project to replace them fifteen years ago, spent more than a billion on designs, getting nothing built, before abandoning its effort and awarding the project to two private companies.

India’s prototype X-37B, dubbed Pushpak, completes third successfully drop test runway landing

10:43 pm

India’s space agency ISRO today successfully completed the third drop test from a helicopter to a runway landing of an X-37B engineering test vehicle, dubbed Pushpak.

The winged vehicle, named ‘Pushpak’, was released from an Indian Air Force Chinook Helicopter at an altitude of 4.5 km. Pushpak autonomously executed cross-range correction manoeuvres, approached the runway, and performed a precise horizontal landing at the runway centerline.

The vehicle also used the same body and flight systems from the previous flight without modifications. Though this is hardly a return from space, the landing profile attempted to duplicate much of that flight path, and thus demonstrated ISRO engineers are on the right track for creating a reusable mini-shuttle.

SpaceX completes two launches today, from opposite coasts

10:37 pm

The bunny marches on! SpaceX successfully completed two launches today.

First, its Falcon 9 rocket launched 22 Starlink satellites from Cape Canaveral in Florida. This was the launch that had been delayed several times by weather, and then by a tecnical launch abort at T-0. After several days of review, it lifted in the morning today with no problems, the first stage completing its eleventh flight, landing on a drone ship in the Atlantic.

Then, about ten hours later a Falcon 9 rocket lifted off in the evening Vandenberg in California, putting 20 Starlink satellites into orbit, 13 of which are said to be designed for direct cell-to-satellite capabilities. This first stage also completed its eleventh flight, landing on a drone ship in the Pacific.

This post is a bit late because we had a five hour power outage in my neighborhood tonight, caused apparently when someone drove into a utility pole and knocked it over.

The leaders in the 2024 launch race:

66 SpaceX

American private enterprise now leads the world combined in successful launches, 77 to 42, while SpaceX by itself still leads the entire world, including other American companies, 66 to 53.

China launches gamma-ray space telescope

9:50 am

China today successfully launched the Space-based Multi-band Variable Object Monitor (SVOM) gamma-ray space telescope, a 20-year-long joint Chinese-French project to monitor astronomical gamma ray bursts.

SVOM was placed in orbit by a Long March 2C rocket lifting off from China’s Xichang spaceport in the southwest of China. No word on where the rocket’s lower stages — which use very toxic hypergolic fuels — crashed inside China. UPDATE: See this video from China. Apparently one stage landed close to homes, spewing that orange hypergolic fuel.

Starliner return delayed again, until July

10:08 pm

NASA tonight announced that it is once again delaying the undocking from ISS and the return to Earth of Boeing’s Starliner capsule, carrying two astronauts, with the return date a as-yet unspecified date in July.

The move off Wednesday, June 26, deconflicts Starliner’s undocking and landing from a series of planned International Space Station spacewalks while allowing mission teams time to review propulsion system data.

It seems to me that they have decided the more time Starliner spends in space right now, the more data they can gather about its flightworthiness in the future. Remember, the first manned Dragon demo mission stayed at ISS for more than two months.

Their approach however — announcing small delays over and over again — is extremely poor PR. It makes it seem as if the capsule’s various issues — thrusters, helium leaks, and valves — are a more serious than I think they are.

Family whose home was damaged by NASA battery ejected from ISS files claim

3:29 pm

The Florida family whose home was damaged when a battery that NASA had ejected from ISS smashed through the roof of its house has now filed an $80,000 claim with the space agency.

Alejandro Otero, owner of the Naples, Florida, home struck by the debris, was not home when part of a battery pack from the International Space Station crashed through his home on March 8. His son Daniel, 19, was home but escaped injury. NASA has confirmed the 1.6-pound object, made of the metal alloy Inconel, was part of a battery pack jettisoned from the space station in 2021.

An attorney for the Otero family, Mica Nguyen Worthy, told Ars that she has asked NASA for “in excess of $80,000” for non-insured property damage loss, business interruption damages, emotional and mental anguish damages, and the costs for assistance from third parties. “We intentionally kept it very reasonable because we did not want it to appear to NASA that my clients are seeking a windfall,” Worthy said.

No lawsuit has been filed so far, as the family is trying to work this out with NASA amicably, and also help set a precedent for future such incidents. NASA in turn gave the family a claim form and is now reviewing the form they submitted.

The article I think is incorrect when it states that this incident “falls outside the Space Liability Convention” (which was written under the Outer Space Treaty) because the debris didn’t come from a foreign country but was launched and de-orbited by an American government agency. The Outer Space Treaty makes whoever launches anything in space liable for any damages. If NASA attempts to fight this it will be violating not only the language but the spirit of the treaty.
