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.

SpaceX’s Falcon Heavy launches NOAA weather satellite

2:37 pm

SpaceX’s Falcon Heavy rocket today successfully launched a NOAA weather satellite, completing its first flight in 2024 and its tenth flight overall.

The two side boosters completed their first flight, with both landing back at Cape Canaveral. The core stage was allowed to fall into the ocean.

The leaders in the 2024 launch race:

67 SpaceX
28 China

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.

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
28 China
8 Russia
8 Rocket Lab

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.

Spanish high altitude balloon company releases artwork of its proposed passenger capsule

9:59 am

EOS-X's balloon capsule
Artist rendering of EOS-X’s balloon capsule

The Spanish high altitude balloon company EOS-X has now released several artist renderings of the proposed capsule that will take passengers on a high altitude balloon flight.

According to the company, the first flights will occur sometime late next year, lifting off from either Seville in Spain or Abu Dabi in the Middle East. The proposed ticket prices range from $160K to $214K, with flights lasting about five hours.

All of this sounds highly speculative, especially because EOS-X in November 2023 was one of two balloon companies indicted by a Spanish court for stealing its balloon concepts from a third company. I have not seen the final decision in that court case, so it is unclear what the long term ramifications might be. It could be that the company which sued, Zero-2, has taken over EOS-X.

Italy approves new space law

9:40 am

Italy’s Council of Ministers yesterday approved language for a new space law and five year space economic plan, designed to regulate the commercial space operations inside Italy as well by Italian companies operating in foreign lands.

In addition to mandating authorization for national and foreign operators who intend to conduct space activities from Italian soil, the law will also regulate the activities of national operators intending to conduct business from foreign territories. One element of regulatory compliance outlined within the law addresses the management of space incidents. Operators will be required to secure insurance coverage of up to €100 million per incident. There are, however, provisions allowing for the potential for lower caps in cases of reduced risk.

More details about the law can be found here. It gives regulatory authority to Italy’s space agency ASI, while also establishing a five-year government program (funding not disclosed) to stimulate the space sector.

The released details are insufficient to find out the real consequences of this law. If written correctly, the regulations could actually make it easier for the private sector to prosper. If not, it could instead squelch new startups as well as existing companies.

SpaceX announces a mini-version of Starlink designed for backpackers

9:28 am

SpaceX today unveiled what it calls Starlink Mini, a smaller version of the Starlink antenna that can fit inside a backpack.

Early Starlink customers were invited to purchase the Starlink Mini kit for $599, according to an invitation sent to customers and viewed by TechCrunch. That’s $100 more than the standard Starlink kit. They were also given the option to bundle Mini Roam service with their existing service plan for an additional $30 per month, though the data is capped at 50 gigabytes per month.

That would mean a Starlink residential customer on the standard service plan would spent $150 month. SpaceX aims to reduce the price of the kit, it said in the invitation. As of now, there is no stand-alone Mini Roam plan.

The unit weighs only 2.5 pounds, with the first deliveries arriving in July. It is designed specifically for travelers who want a reliable internet connection wherever they go.

Nova Scotia spaceport approved for new government grants

9:23 am

The proposed Nova Scotia spaceport run by the company Maritime Services has now been approved to apply for new government grants for its proposed satellite processing facility.

The Nova Scotia CITC is an annualized reimbursement program designed by the Government of Nova Scotia to drive economic growth and incentivize development within Nova Scotia. The program provides significant financial advantages to eligible corporations that invest in infrastructure and capital equipment for approved projects located in Nova Scotia.

Maritime Launch has received approval for an initial qualification of up to $7.5M in reimbursements under the CITC for the satellite processing facility project. Reimbursement is eligible to begin at the start of the construction of the satellite processing facility, planned for late 2024 and follows approval of a separate application in September 2023 for a project at Spaceport Nova Scotia.

Maritime Launch has been around since 2016 but as of this moment it is unclear when the first orbital launch from the spaceport will occur. Initially the plan had been to provide both spaceport and a Ukrainian rocket for satellite makers, but the Ukraine war ended that plan. Now the spaceport offers its facility to any rocket company, but so far no launch company has yet signed a launch deal.

Japan’s space agency reveals it was hacked in 2023

9:02 am

Japan’s space agency JAXA today revealed that beginning in 2023 and periodically into this year it has been attacked repeatedly by hackers, with data from more than 10,000 files stolen.

Attacks occurred in June 2023 and multiple times a year, although investigations are ongoing regarding whether more information was stolen in this year’s attacks.

In addition to internal data, potentially compromised entities include NASA, Toyota Motor Corp., Mitsubishi Heavy Industries Ltd. and the Defense Ministry, with which JAXA has nondisclosure agreements. Information from numerous aerospace and defense-related organizations and companies was also exposed.

JAXA stated that no sensitive information related to national security or rocket technologies was stolen in last year’s breach. Personal data of approximately 5,000 JAXA personnel and employees from partner companies was used to access the Microsoft 365 accounts of JAXA executives.

It appears JAXA officials only found out about the attack when police told them about it months after the June 2023 attack. Agency officials now say no sensitive rocket or satellite data was stolen. Instead, it appears the attack targeted personal communications as well as research facilities.

The report provided no indication about the source of these attacks, but noted that a 2016 attack is known to have come from China.

This was Rocket Lab’s 50th launch, putting this company among a very small club of private companies, which includes SpaceX and ULA. Governments and government-owned entities (such as Arianespace) have done more, but that is going to change in the coming years as private enterprise takes over.

Update on SpaceX activities leading to the next Superheavy/Starship orbital test flight

9:36 am

Link here. Lots happening, including fueling and static fire tests of Starship prototype #26 (which will not fly) and major changes on Starship prototype #30, which is slated to make that fifth test flight:

Ship 30 continues to receive upgrades, preparing it for Flight Five. Now, with most of the older tiles removed [18,000 total], new similar-sized tiles are being attached to Ship 30. These tiles could potentially have a different formula, which would make them more resistant to heat while holding a similar size.

Also, an ablative pyron layer is being added to the hot spots where Ship 30 is most likely infiltrated by plasma during entry. Pyron is used in the Falcon 9’s engine bay and is a material that SpaceX knows and trusts.

SpaceX has said it is targeting July for the flight, and the FAA has said the company’s launch license will allow it to launch whenever it is ready, with no FAA red tape to stand in the way.

Blue Origin signs deal to fly Nigerian on New Shepard suborbital flight

9:29 am

As part of what is now a general pattern of using New Shepard suborbital flights for feel-good public relations stunts, Blue Origin has now signed a deal to fly a Nigerian into space sometime this year or next.

A lot of government and charitable entities appear involved in this deal.

The Space Exploration & Research Agency (SERA) [private charity] and the National Space Research and Development Agency (NASRDA) [Nigeria’s space agency] have signed a partnership agreement to execute an exploration project that will send the first Nigerian citizen into space. This collaboration marks a significant milestone in Nigeria’s space exploration journey and opens new opportunities for scientific research and technological advancement.

Under this partnership, SERA, a global space agency dedicated to increasing access to space for all nations, will reserve a seat on an upcoming Blue Origin New Shepard suborbital spaceflight for a Nigerian citizen.

According to a statement shared with Technext, this is part of a broader SERA-led initiative, in partnership with Blue Origin, to send six individuals from nations historically underrepresented in space exploration.

In addition, a Nigerian non-profit, Learnspace, appears to have played a part in working out this deal. As for SERA, I suspect its funding mostly comes from Jeff Bezos or Blue Origin.

Either way, the deal appears to open the competition to any Nigerian citizen, with the final decision partly influenced by public voting.

German rocket startup Isar raises another €65 million in investment capital

9:09 am

The German rocket startup Isar Aerospace has now raised an additional €65 million in investment capital, bringing the total invested in the company to €400 million ($428 million).

Interestingly, a major backer appears to be a governmental entity.

The funding round extension received significant involvement from the NATO Innovation Fund (NIF), a venture capital fund backed by 24 NATO allies focused on addressing challenges in defence, security, and resilience.

…In addition to NIF, the funding round included contributions from G3T, 10x Group, Besant Capital, Finadvice Med HOLDINGS, LP&E, and existing investors Lakestar, Earlybird, Airbus Ventures, Bayern Kapital, and UVC Partners.

Isar has deals to launch its proposed Spectrum orbital rocket from French Guiana and from the new commercial spaceport in Andoya, Norway. The company however initially promised in 2021 that its first launch from Andoya would take place in 2022, with no launch occurring. In fact, of the three German rocket startups, Isar is the only one to so far not do a test launch of any kind, and it is presently unclear when that first orbital test launch of Spectrum will occur.

Astronomers see a quiet galaxy become active for the first time

9:46 am

Using a number of space- and ground-based telescopes, astronomers have for the first time seen in real time what had previously been a very inactive and quiet galaxy become active and energetic, suggesting a major event at the galaxy’s center had taken place to change its behavior.

From the abstract of the paper [pdf]:

We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 10 6 M ⊙ AGN [a one million solar mass black hole] that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGN observed in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour.

As noted in the press release:

Some phenomena, like supernova explosions or tidal disruption events — when a star gets too close to a black hole and is torn apart — can make galaxies suddenly light up. But these brightness variations typically last only a few dozen or, at most, a few hundreds of days. SDSS1335+0728 is still growing brighter today, more than four years after it was first seen to ‘switch on’. Moreover, the variations detected in the galaxy, which is located 300 million light-years away in the constellation Virgo, are unlike any seen before.

If the central black hole is switching from being quiet to active, this galaxy is providing astronomers critical information for understanding such changes. This is particularly important to us here in the Milky Way, which has a very inactive central supermassive black hole weighing about 4 million solar masses. It would be very useful to understand what would cause it to become active, especially because such an event might even have an impact — possibly negative — throughout our entire galaxy.

Scientists release first image from Hubble in one-gyro mode

9:29 am

First Hubble image in one-gyro mode
Click for original image.

The Hubble science team today released the first image from the Hubble Space Telescope produced in its new one-gyro mode.

That image it so the right, cropped, reduced, and sharpened to post here, and shows NGC 1546, a nearby galaxy in the constellation Dorado about 52 million light years away. The inset shows at full resolution the small red galaxy near the top, to give some sense of the telescope’s capabilities in this one-gyro mode.

The details astonish me, and prove my pessimism about this new mode to have been wrong. I expected future images to be more fuzzy, with Hubble’s ability to take sharp images largely limited. The resolution here is excellent, and bodes well for future science observations.

Nonetheless, the telescope is still working under major limitations:

Although one-gyro mode is an excellent way to keep Hubble science operations going, it does have limitations, which include a small decrease in efficiency (roughly 12 percent) due to the added time required to slew and lock the telescope onto a science target.

As previously noted, prior to the use of the fine guidance sensors, fixed head star trackers position Hubble’s pointing closer to the target. If Earth or the moon block two of the fixed head star trackers’ fields of view, Hubble must move further along in its orbit until the star trackers can see the sky and its stars again. This process encroaches upon science observation time. Second, the additional time the fine guidance sensors take to further search for the guide stars adds to the total time the sensors use to complete the acquisition.

Third, in one-gyro mode Hubble has some restrictions on the science it can do. For example, Hubble cannot track moving objects that are closer to Earth than the orbit of Mars. Their motion is too fast to track without the full complement of gyros. Additionally, the reduced area of sky that Hubble can point to at any given time also reduces its flexibility to see transient events or targets of opportunity like an exploding star or an impact on Jupiter.

When combined, these factors may yield a decrease in productivity of roughly 20 to 25 percent from the typical observing program conducted in the past using all three gyros.

It really is time for the astronomical community to get its act together and begin work on developing and launching more large optical telescopes into space. Hubble has shown us the potential of in-space optical astronomy. That astronomers have not flocked in the last three decades to build more such telescopes is puzzling beyond belief.
