Europe at last launches Ariane-6

12:47 pm

Ariane-6 seconds after liftoff
Ariane-6 seconds after liftoff

Arianespace, the commercial rocket arm of the European Space Agency (ESA) today successfully completed the first launch of its new Ariane-6 rocket, lifting off from French Guiana in South America carrying nine cubesats plus two re-entry test capsules.

As of posting, the nine cubesats have been deployed. Of the remaining payloads, one is a smallscale version of the return cargo capsule being built by the French company The Exploration Company. It will test the re-entry technology for that capsule.

UPDATE: There was an issue restarting the upper stage later in the flight that prevented the last payloads from being released. The bigwigs at the press conference at this link repeatedly insisted the flight was a complete success, but this failure of the upper stage is not a good thing, but hardly a disaster. It is similar to problems Firefly had on some of its early flights, which the company was able to overcome.

If all goes as planned, Arianespace and Arianegroup (the private company that builds and owns the rocket) hope to ramp up launches over the next three years, doing one more in 2024, six in 2025, eight in 2026, and ten in 2027. It says the rocket has contracts for thirty launches, eighteen of which are for launching Amazon’s Kuiper internet constellation.

I expect Ariane-6 to face heavy competitive pressure over that time period, not only from SpaceX but from the new European rocket startups that should begin launching at far less cost. The pressure should make the future of Ariane-6 somewhat dim, unless the European Union steps in and mandates its use by European satellite companies. If the latter happens, expect Europe’s entire space industry to suffer badly.

This was Europe’s first launch in 2024, so the leader board in the 2024 launch race has not changed:

71 SpaceX
30 China
8 Russia
8 Rocket Lab

American private enterprise still leads the world combined in successful launches, 83 to 46, while SpaceX by itself still leads the entire world, including other American companies, 71 to 58.

A jumble of blocks in the middle of a Martian flood lava plain

11:25 am

A jumble of blocks on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on March 18, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

This is one of what I like to call “What the heck?” images. The broken up blocks resemble ice floes on the edge of the Arctic ice cap that have broken off and have begun floating away.

The problem with this theory is many fold. First, this is on Mars and not on Earth. Second the “sea” these blocks are supposedly “floating” in is actual solid lava. There is no water or ice here, on the surface or even underground. This is in the dry tropics of Mars, where little or no near-surface ice has so far been detected.

The overview map below provides some context, and possibly an explanation.

Japan dithers about capitalism in space

9:38 am

Despite its government creating in November 2023 a new “Space Strategic Fund” worth more than $6 billion designed to encourage capitalism in space and handing it to Japan’s space agency JAXA to administer, JAXA officials continue to dither on how to use that money to encourage private enterprise in space.

Japan’s space agency is seeking industry proposals for technologies that could contribute to future commercial space stations as the government studies what role it would play in supporting efforts to replace the International Space Station.

…That work will inform plans by Japan on how it can participate in commercial space stations being developed by American companies in partnership with NASA. “We are discussing how we will join NASA’s Commercial LEO Destination program,” said [Yasuo Ishii, senior vice president of JAXA]. “Our responsibility is not clear yet, but, of course, commitment at the government level is essential to commercial operations.” [emphasis mine]

The highlighted phrases above reveal the underlying motives of JAXA, which is not to encourage private independent space companies and reduce its involvement. Just the opposite. And it appears Japan’s government is a partner in this. While Japan gave that money to its space agency, which seems to be searching for ways to hold onto its power, both Europe and India instead quickly took power and funding away from their government agencies (Arianespace and ISRO respectively) to encourage independent private space companies to flourish.

This dithering will only put Japan further behind these countries as well as China, a reality that has become increasingly embarassing for the island nation.

Webb: Hot Jupiter exoplanet has atmosphere with the smell of rotten eggs

9:20 am

Using spectroscopy from the infrared Webb Space Telescope, astronomers have measured some of the molecules in exoplanet HD 189733 b, one of the first hot Jupiter exoplanets ever discovered, and found it has an atmosphere rich in hydrogen sulfide, which emits a smell like rotten eggs.

In addition to detecting hydrogen sulfide, the team analyzed the planet’s oxygen and carbon content, pinpointing water, carbon dioxide and carbon monoxide as major components of the planetary atmosphere. Measuring these heavy elements allows astronomers to compare the composition of exoplanets to that of gas giants in our solar system like Jupiter and Uranus.

The exoplanet, about 64 light years away, has an orbit lasting only about two Earth days, with atmospheric temperatures has hot as 1,700 degrees Fahrenheit.

Watch the first launch of Europe’s Ariane-6 rocket

9:14 am

Europe’s Ariane-6 rocket, first proposed in 2014 and about four years behind schedule, will finally make its first launch at 2 pm (Eastern) today.

I have embedded the live stream below.

The rocket was conceived by the European Space Agency (ESA) as an attempt to compete with SpaceX’s Falcon 9 rocket. It failed to do this from day one, since the rocket was from day one designed to be expendable. By the 2020s it became clear to European satellite companies and government agencies that its launch cost would be far higher that the Falcon 9, and these companies and agencies have therefore resisted signing launch contracts with ArianeGroup. In fact, if Amazon had not decided in ’22 to give the Ariane-6 a contract for 18 launches to put up its Kuiper satellites, the rocket would have almost no launches in its manifest.

This situation was made even more starkly evident at the end of June, when the European governent weather company Eumetsat cancelled its Ariane-6 contract and switched to the Falcon 9.

Though the unelected bureaucrats and apparatchiks in the European Union are trying to require the use of Ariane-6, ESA and Europe’s rocket future resides in the independent rocket startups (Rocket Factory Augsburg, Isar Aerospace, Hyimpulse, PLD). Because they are in competition with each other as well as SpaceX, and are not saddled with heavy government interference, they can focus on innovating to lower cost. Expect them to quickly begin launching in the next three years, with reusability soon to follow.

SpaceX launches Turkey’s first homebuilt geosynchronous communications satellite

4:39 pm

SpaceX today successfully launched Turkey’s first homebuilt geosynchronous communications satellite, its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage completed its fifteenth flight, landing on a drone ship in the Atlantic. The fairings on this flight completed their tenth and sixteenth time, respectively.

The leaders in the 2024 launch race:

71 SpaceX
30 China

SpaceX releases new video of the fourth Starship/Superheavy test flight in June

9:35 am

SpaceX on July 4, 2024 released a new compliation video of the fourth Starship/Superheavy test flight in June, showing some footage not previously released.

I have embedded it below. As is the policy now of many rocket companies as well as many space agencies worldwide, SpaceX added a pounding music score to the event. While sometimes this is fun, I must admit that I am finding it increasingly annoying. This is not a movie, it is real life. If anything, I think the music robs this particular event some of its magnificence by trivializing it.

But then, what do I know?

At the end, SpaceX teased a launch tower capture of Superheavy on the next flight, but I still think this is not going to happen because of the delays it would cause getting FAA approval.

A drainage gully on Mars?

11:25 am

A drainage gully on Mars?
Click for original image.

Overview map

Cool image time! The picture above, cropped, reduced, and sharpened to post here, was taken on April 18, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a gully that cuts down from the western rim of a 21-mile-wide unnamed crater in the southern cratered highlands of Mars.

The small rectangle on the overview map to the right marks the location, with the inset providing a close-up of this crater, with the white bar indicating the area covered by the photo above. The overall elevation loss from the rim on the left down to the crater floor on the right is about 3,800 feet.

The first high resolution picture of this gully was taken in 2016, with subsequent pictures taken in 2021 and 2022. In comparing the newest picture above with the 2016 photo I can detect no changes, but I am not looking a the highest resolution available. In addition, both of these pictures were taken during the Martian spring. The 2021 and 2022 pictures were taken during the Martian summer, and in both the north-facing wall where the gully is beginning to narrow seemed brighter.

It is likely the researchers are looking to see if any frost — either ice or dry ice — appeared during the winter and then sublimated away in the summer. Such a change could cause some of the erosion that produced this gully.

ESA approves taking the Vega-C rocket away from Arianespace

9:12 am

The council that runs the European Space Agency (ESA) today approved a resolution that shifted ownership of the Vega-C rocket away from government-run Arianespace and giving it back to its builder, the Italian aerospace company Avio.

Arianespace and Avio have agreed that Arianespace will remain the launch service provider and operator for Vega and Vega-C launch services until Vega flight 29 (VV29), scheduled for the fourth quarter of 2025. For Vega-C launches following VV29, the customers who have already contracted with Arianespace will be offered the possibility to transfer their contracts to Avio as the new launch service provider and sole operator of Vega.

Arianespace will primarily focus with ArianeGroup on the Ariane 6 exploitation to best meet the customer needs.

The council also agreed with France’s plan to allow independent commercial rocket startups to launch from French Guiana. Control of that spaceport has also been taken from Arianespace and returned to its owner, the French space agency CNES.

Essentially, this decision ties Arianespace’s future to Ariane-6, which is likely to disappear once its present manifest of launches, mostly for Amazon’s Kuiper constellation, gets launched.

Kazakhstan joins China’s lunar base project

9:03 am

Kazakhstan today became the twelth nation to join China’s International Lunar Research Station (ILRS) project, and the first besides Russia with a real viable space industry.

The agreement appears to also include language allowing both nations to use each other’s spaceports. Since Kazakhstan’s main area of participation in space is its Baikonur spaceport, built during the Soviet days and up to now used exclusively by the Russians, this agreement could be a big deal. As the article notes,

China is currently working to boost pad access for emerging commercial launch service providers. The Baikonur cosmodrome was set up by the Soviet Union in Kazakhstan. It is leased to Russia until 2050. The country also hosts the Sary Shagan Test Site. Kazakhstan shares a border with Xinjiang, in China’s west.

“Kazakhstan will need to diversify away from Russia if it wants to have a big future in space,” Bleddyn Bowen, an associate professor specializing in space policy and military uses of outer space at the University of Leicester, told SpaceNews.

This deal indicates once again the foolishness of Russia’s invasion of the Ukraine. It highlighted to all of its neighbors that they need to form alliances with others to strengthen their hand should Russia turn its aggressive eye in their direction. Kazakhstan has now done so, to Russia’s long term detriment.

China’s twelve partner nations are Azerbaijan, Belarus, Egypt, Kazakhstan, Nicaragua, Pakistan, Russia, Serbia, South Africa, Thailand, Turkey, and Venezuela. In addition, about eleven academic or governmental bureaucracies have signed on along with several other countries (Bahrain and Peru) who have not signed on but are involved in other ways.

China launches “satellite group” of Earth observation satellites

8:50 am

According to China’s state-run press, a Long March 6A rocket today successfully launched a “group of satellites … for geographic mapping, land resource surveys, scientific experiments and other purposes,” lifting off from its Taiyuan spaceport in northeast China.

No further information was provided, including where the rocket’s oxygen-fueled lower stages and its four solid-fueled strap-on boosters crashed inside China.

The leaders in the 2024 launch race:

70 SpaceX
30 China
8 Russia
8 Rocket Lab

American private enterprise still leads the world combined in successful launches, 82 to 45, while SpaceX by itself still leads the entire world, including other American companies, 70 to 57.

Space Force adds Stoke Space and Blue Origin to its list of smallsat launch companies

9:59 am

The Space Force has now added rocket startups Stoke Space and Blue Origin to its list of launch companies who are now approved to bid on launches of the military’s small satellites.

The two firms join 10 other vendors in the OSP-4 pool: ABL Space Systems, Aevum, Astra, Firefly Aerospace, Northrop Grumman, Relativity Space, Rocket Lab, SpaceX, United Launch Alliance (ULA), and X-Bow.

This program is designed for launches that are not critical and can be used to help new rocket companies, while also encourage all the companies to move more quickly, as the contracts are designed to be require a launch within 12 to 24 months after award, and sometimes much sooner. For example, several recent Firefly launches required the company to deliver the payload to the assembly building and get it mounted in less than a few days, and to do so only when told by the military.

This military smallsat launch program is also wholly different than the Space Force’s large payload launch program, which presently only allows SpaceX, ULA, and Blue Origin to bid on launches. With both programs however it appears the military is no longer limiting the companies that can bid to as small a number as possible — which had been its policy for the first two decades of this century — but instead is eagerly expanding the number over time to increase competition and its own options. With the large payload program the Pentagon intends to revisit its list yearly to widen it as new companies mature.

Payload for the last launch of Avio’s Vega rocket now heading to French Guiana

9:44 am

While it remains unclear when the launch will occur, the two-satellite payload for the last launch of Europe’s Vega rocket is now heading to French Guiana.

The payload is two satellites that will be placed in orbits 180 degrees apart in order to make it possible to make fast repeat coverage of the Earth.

This particular launch is long delayed, for several reasons, one of which has been extremely embarrassing for Avio, the Italian company that builds the Vega family of rockets.

In December 2023, European Spaceflight reported that Avio had lost two of four propellant tanks required for the upper stage of the rocket’s final flight. The tanks were later found crushed, forcing the company to find an alternative. At the time, it proposed either using test articles of the tanks that had been used during the vehicle’s qualification phase in 2012 or modifying Vega C upper stage propellant tanks. It’s not clear which of the two options Avio selected to pursue.

The lack of any announced launch date suggests Avio might still have not come up with a solution, or if it has, the solution is not yet fully implemented.

Isaacman’s Polaris Dawn mission to launch July 31, 2024

9:32 am

Jared Isaacman
Jared Isaacman

According to a short notice on the Polaris Dawn webpage, Jared Isaacman’s manned orbital mission where he will do the first spacewalk by a private citizen is now targeting a launch date of July 31, 2024.

The four-person mission is planned to spend five days in orbit in SpaceX’s Resilience Dragon capsule, during which it will fly to as high as 870 miles, the highest orbit flown since Gemini 11 in 1966, and the farthest any human has flown from Earth since the Apollo lunar missions. That orbit will make possible some new radiation research:

[T]his is high enough to penetrate the inner band of the radioactive Van Allen Belts that encircle the Earth. This isn’t good for the crew consisting of Mission Commander Jared Isaacman, Mission Pilot Scott Poteet, Mission Specialist Sarah Gillis, and Mission Specialist and Medical Officer Anna Menon, but their initial orbit will be highly elliptical with a lower altitude of 120 miles (190 km), so their exposure will be minimal.

The purpose of this radiological game of chicken is to conduct 38 science experiments to study the effects of spaceflight and space radiation on human health. When these are completed, the altitude for the remainder of the five days in orbit will be reduced to 430 miles (700 km).

Isaacman will then attempt his spacewalk, opening a hatch on Resilience that replaced its docking port. While Isaacman will be the only one to exit the capsule, all four crew members will be in comparable spacesuits, since the capsule has no airlock and thus its entire atmosphere will escape during these activities.

If this mission is successful, I expect Isaacman will renew his push at NASA for making the goal of his next Polaris mission to replace the gyros on the Hubble Space Telescope. At the moment agency officials have expressed skepticism and seem uninterested. That might change however.

Firefly’s Alpha rocket launches eight smallsats into orbit

9:13 pm

Firefly tonight successfully launched eight smallsats for NASA and others, its Alpha rocket lifting off from Vandenberg in California.

The payloads on this launch were not all built by NASA, but I think NASA paid the launch costs as part of a program to help startups. One payload, Catsat, is a test of a spherical inflatable antenna created by the startup Freefall. If successful, it will be make it possible for cubesats to transmit much more data than they can now. As of posting seven of the eight satellites had been deployed. Catsat’s deployment however had not been confirmed.

As this was Firefly’s first launch in 2024, the leader board of the launch race does not change:

70 SpaceX
29 China
8 Russia
8 Rocket Lab

American private enterprise however now leads the world combined in successful launches, 82 to 44, while SpaceX by itself still leads the entire world, including other American companies, 70 to 56.

Firefly postpones its next launch attempt to review data

9:31 am

Firefly yesterday scrubbed its second attempt to launch eight cubesats for NASA and others using its Alpha rocket, postponing the next launch attempt in order to the review the ground system issue that caused the two launch aborts on the first launch attempt on July 1, 2024.

In a social media post, the company stated that it’s standing down “to give the team more time to evaluate data and test systems from the first attempt. … We will work closely with the range and our NASA customer to determine the next launch window,” Firefly wrote on X.

This would have been Alpha’s fifth orbital launch. No new launch date has been announced, though it is expected to occur before the end of this month.

Though it has only flown a few times (with some of those launches failures or only partially successful), Firefly’s Alpha rocket has a robust launch manifest, with its biggest contract with Lockheed Martin for 25 launches. It has signed deals to launch from Wallops Island and Vandenberg, as well as the Esrange spaceport in Sweden. And it also has a contract to build the first stage for Northrop Grumman’s Antares rocket.

Two German-built spy satellites apparently failed immediately after launch

9:17 am

According to a report in the German press, two spy satellites launched in December 2023 apparently never became operational because the antennas on both failed to deploy.

According to the German publication Der Spiegel, the antennas on the satellites cannot be unfolded. Engineers with OHB have tried to resolve the issue by resetting the flight software, performing maneuvers to vibrate or shake the antennas loose, and more to no avail.

As a result, last week, German lawmakers were informed that the two new satellites will probably not go into operation as planned.

The report also notes that, because both satellites never became operational, they remain the responsibility of the building, a German company OHB. It will have to replace them out of its own pocket. It also appears that the company never tested the antenna deployment system prior to launch.

SpaceX gets NASA contract to launch gamma-ray space telescope

9:09 am

NASA yesterday announced that it has awarded SpaceX a contract to launch a new gamma-ray space telescope, dubbed the Compton Spectrometer and Imager (COSI), using its Falcon 9 rocket and targeting an August 2027 launch date.

The firm-fixed-price contract has a value of approximately $69 million, which includes launch services and other mission related costs. The COSI mission currently is targeted to launch August 2027 on a SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station.

This wide-field gamma-ray telescope will study energetic phenomena in the Milky Way and beyond, including the creation and destruction of matter and antimatter and the final stages of the lives of stars. NASA’s COSI mission will probe the origins of the Milky Way’s galactic positrons, uncover the sites of nucleosynthesis in our galaxy, perform studies of gamma-ray polarization, and find counterparts to multi-messenger sources. The compact Compton telescope combines improved sensitivity, spectral resolution, angular resolution, and sky coverage to facilitate groundbreaking science.

The stated launch price gives us a sense of what SpaceX is charging these days for launches. The contract award also illustrates once again why the delays in developing ULA’s Vulcan and Blue Origin’s New Glenn rockets — caused by Blue Origin’s difficulties in manufacturing its BE-4 rocket engine — has ended up costing both companies a lot of money in sales. SpaceX keeps getting these launch contracts because Vulcan and New Glenn are not yet flying operationally. Vulcan has flown once, but it is probably isn’t capable of adding additional launches to is manifest. More important, the rocket is not yet reusable, and probably could not match SpaceX’s price.

As for New Glenn, it supposedly will make its first launch this fall, but we shall see. It remains four-plus years behind schedule, and though it is described as reusable, its first stage landing vertically like a Falcon 9, it is doubtful it will become doing this on its first launches. It needs to prove out its systems first.

Las Vegas space-related resort (claiming it will be a spaceport) gets FAA airport license

8:56 am

A project to build a space-related resort near Las Vegas has now obtained an airport license from the FAA.

The Federal Aviation Administration said small aircrafts can take off from the site of the Las Vegas Executive Airport, which is proposed to be built on about 240 acres of rural land about 45 minute drive away from Las Vegas. The plan is to develop the site into a Las Vegas Spaceport, according to a news release.

The FAA approval said it doesn’t oppose an airport at the site, the proposed takeoffs won’t need clearance from air traffic control and won’t operate in FAA-controlled airspace. If the airport wants to change any of its operations, it would need FAA approval.

The project, dubbed the Las Vegas Spaceport, intends to build a hotel and space-related training facilities to attract space geeks, and claims it will eventually add a launchpad, but considering its location, that last claim is very unlikely. The airport license however will allow it to add flight-training to its portfolio.

SpaceX launches 20 Starlink satellites

8:27 am

SpaceX early this morning launched another 20 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage completed its sixteenth flight, landing on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

American private enterprise now leads the world combined in successful launches, 81 to 44, while SpaceX by itself still leads the entire world, including other American companies, 70 to 55.

To get a sense of how incredible SpaceX’s launch pace this year has been, those 70 launches, completed in only days more than first half of the 2024, matches the American record for launches in a entire year, that was set in 1966 and remained the record until 2022.

Centrifuge research on ISS suggests some artificial gravity can mitigate negative effects of weightlessness

1:30 pm

Two of the three centrifuges on ISS

When I appeared on the Space Show last month I stated something about centrifuge research that was wrong. I had been under the false impression that no such research had yet been done on ISS, and our only data came from one experiment performed by the Soviets on one of their early space stations decades ago.

Charles Lurio, who writes the very respected Lurio Report newsletter on space matters, called me afterward to correct me, and then followed up by sending me a link to a paper describing research on ISS in the past few years using rats inside three different small centrifuges (two of which are shown in the picture to the right). For this information I thank him.

You can download the paper here [pdf]. The research is significant because it suggests that the medical problems of weightlessness can be solved by creating an artificial gravity far less the Earth’s 1g environment. From the paper’s abstract:

Geology on Mars is not always what you think it is

12:49 pm

The Martian tropics versus the Martian south pole
For the original images go here and here.

Today’s cool image is actually a comparison of two different high resolution images from Mars Reconnaissance Orbiter (MRO), both of which illustrate why it is very dangerous to come to any conclusions about such images without knowing a lot more about them.

The top image to the right, cropped to post here, was a terrain sample image taken on March 30, 2024. Such images are usually taken not to complete any particular research project, but are taken to fill a gap in the schedule in order to maintain the camera’s proper temperature. When the camera team has to do this, they attempt to pick a spot that might have some geological interest. Sometimes they get something surprising. Often however the features in the picture are boring.

In this case they spotted a place where the ground appears appears to be eroding away in a random pattern.

The bottom image, cropped, reduced, and enhanced to post here, was taken on March 24, 2024 and was part of planned research. It shows a section of the Martian south ice cap, specifically the area where scientists believe there is a residual permanent small cap of dry ice on top of a thick underlying water ice cap.

Like the top image, the features here suggest some sort of erosion process eating away randomly at the ground’s upper layers.

The two images illustrate the difficulty of interpreting orbital images. At first glance the geological features of both appear very similar. Yet the top image is located in the very dry equatorial regions of Mars, and in fact is inside the Medusae Fossae Formation, the largest field of volcanic ash on the red planet. The layers here are likely ash, and the erosion that carved out the hollows likely came from wind. If there ever was near-surface ice at this location, it was many eons ago.

The bottom image however likely shows the sublimation process that is slowly eating away at the residual dry ice cap at the south pole. The Martian north pole does not have residual permanent cap of frozen carbon dioxide, and the reasons why the two caps are different in this way are complex and not completely understood.

Both images show erosion that produces features that look similar. But the materials involved and the causes are completely different.

Remember this when you look at any orbital picture taken of Mars, or any other planetary object. Without the larger context (location, make-up, known history), any guess about the nature of the features there is nothing more than a wild guess, no different than throwing darts at a wall while wearing a blindfold.

Webb takes false-color infrared image of bi-polar protostar nebula

10:02 am

Hourglass nebula as seen in infrared by Webb
Click for original image.

Scientists using the Webb Space Telescope have now produced a new false-color infrared image of the bi-polar hour-glass-shaped protostar nebula dubbed L1527.

That image is to the left, created from data from Webb’s MIRI (Mid-Infrared Instrument) and cropped, reduced, and sharpened to post here. While it is not quite a pretty as a prevous Webb infrared image taken in 2022 by its NIRCam (Near-Infrared Camera), it provides new information about the make-up of materials within this nebula. From the caption:

The areas colored here in blue, which encompass most of the hourglass, show mostly carbonaceous molecules known as polycyclic aromatic hydrocarbons. The protostar itself and the dense blanket of dust and a mixture of gases that surround it are represented in red. (The sparkler-like red extensions are an artifact of the telescopes’s optics). In between, MIRI reveals a white region directly above and below the protostar, which doesn’t show as strongly in the NIRCam view. This region is a mixture of hydrocarbons, ionized neon, and thick dust, which shows that the protostar propels this matter quite far away from it as it messily consumes material from its disk.

Previous to Webb, this object had mostly been studied in 2012 using radio and submillimeter wavelengths (see the papers here and here), but those papers determined this is possibly the youngest known protostar, less than 100,000 years old.

Florida approves expansion of spaceport territories

9:32 am

Map of potential Florida spaceports

The Florida legislature has now approved two new locations in Florida where rocket launches can take place.

Governor Ron DeSantis signed off on a bill that, as of Monday, will add South Florida’s Homestead Air Reserve Base and the panhandle’s Tyndall Air Force Base to Florida’s growing spaceport territories.

The map to the right shows the spaceport locations within Florida. While the state government might now allow launches from these locations, it is unclear if either military facility is entertaining the idea.

Regardless, the Florida government is clearly intent on encouraging and attracting this new industry to its state.

Blue Origin expands deal to fly citizens free on New Shepard

9:16 am

Blue Origin, in partnership with a non-profit, has expanded its program to fly citizens free on suborbital flights of New Shepard, adding India and what it calls “the small island developing states (SIDS)” to the recently announced deal to fly a Nigerian.

The non-profit, dubbed Space Exploration and Research Agency (SERA), has purchased one seat on each of the next half dozen flights, and will only charge passengers $2.50 for the ticket.

In an unprecedented move, SERA will allow people around the world to vote on which citizens will take the approximately 11-minute journey. Anyone living in one of the program’s partner nations can apply to secure a seat. Applicants must be proficient in English, at least 18 years of age, and meet Blue Origin’s parameters for height, weight, physical fitness, and citizenship.

Five of the seats will be allocated to specific nations, and candidates will be voted on by citizens of those nations. The sixth will be open to anyone within a SERA-partnered country and chosen through a global vote. Remaining seat assignments will be announced later this year.

Overall, this continues the PR stunt nature of Blue Origin’s suborbital New Shepard, which apparently does not have enough business to fill its passenger manifest, and thus is arranging these give-aways. While the gesture is nice, it would be far better if the company got its orbital rocket off the ground and actually began flying real cargos and passengers into space.

PLD pushes for first orbital launch from French Guiana in 2025

The Spanish rocket startup PLD announced last week that it has invested more than $10 million in developing its own launchpad and assembly facility at France’s French Guiana spaceport, and is targeting 2025 for the first orbital launch of its Miura-5 rocket.

The launcher company PLD Space has announced today an investment of 10 million euros in MIURA 5 Launch Complex at Guiana Space Center (CSG), Europe’s spaceport in Kourou (French Guiana), owned by the French Space Agency (CNES) and the European Space Agency (ESA). With the first launch of its rocket at the end of 2025, PLD Space will become the first non-institutional launch operator that will go to orbit from this historical base.

The company is reconfiguring the launchpad used by France to launch its Diamant rocket back in the 1960s and 1970s. It will include “its own launch zone and a preparation area, comprising an integration hangar, a clean room, a control center, and both commercial and work offices.”

Right now it appears that PLD along with several other European rocket startups are going to bypass a number of American rocket startups that had had a significant headstart, but also appear to be stalled in the last year or so because of a new regulatory framework at the FAA.

A new Polish suborbital rocket, dubbed “ILR-33 Amber 2K,” and being developed by the Łukasiewicz Institute of Aviation, will do its next test flight from the Andoya spaceport in Norway.

After four consecutive test missions completed successfully in Poland, the next stage of preparations of the ILR-33 AMBER 2K to reach the edge of space will take place this year in July. Polish technology will be tested in Norway where one of the key European space centers for launching space vehicles is located.

According to this report, this rocket has a core stage with a hybrid-fueled engine plus two strap-on solid-fueled boosters, a configuration rare for suborbital rockets. After this test flight it will then begin operational suborbital flights, run by a Polish company Thorium from 2025 to 2027.

This deal is another competitive blow to the Saxaford and Sutherland spaceports in the United Kingdom. Both started commercial operations years ahead of either Andoya or Esrange, but because of red tape nothing has been yet allowed to launch from either. This Polish deal one of several for both the Andoya and Esrange spaceports that might have gone to the UK otherwise.

SpaceX studying changes to de-orbit procedures for Dragon service module

10:09 am

Because it appears the trunk section of the service module of SpaceX’s Dragon capsules actually survives re-entry, the company is now studying changes to its de-orbit procedures so that it can guarantee that trunk will not crash on land, as has happened now three times in the past two years.

The solution [a NASA official] said NASA and SpaceX are looking at involves changing deorbiting procedures. Currently, the trunk is released before the capsule performs its orbit burn. That means the trunk can remain in orbit for months before making an uncontrolled reentry.

Instead, [that NASA official] said engineers are examining doing the deorbit burn and then releasing the trunk. That would provide more control of where the trunk reenters, ensuring that any debris that survives reentry lands in unpopulated regions.

To make this new procedure work they need to recalculate the fuel requirements for doing the de-orbit burn. It also requires them to figure out when to detach the trunk after the burn. I expect SpaceX to successfully implement these changes before the next Dragon launch, whether manned or unmanned.

Ispace’s Resilience lunar lander completes thermal vacuum testing

10:01 am

The Japanese startup Ispace announced late last week that its second lunar lander, formerly names Hakuto-R2 and now dubbed Resilience, has successfully completed thermal vacuum testing and is on schedule for a launch before the end of this year.

The testing was completed at the Japan Aerospace Exploration Agency (JAXA) Tsukuba Space Center in Tsukuba, Japan, where the agency operates a large testing facility. The flight model was assembled at the facility and all payloads or testing models were integrated into the lunar lander before testing began. All test success criteria were met; ispace engineers are now reviewing the detailed data that RESILIENCE collected during the ten-day testing regime. The results will allow engineers to optimize the spacecraft thermally for spaceflight as well as improve flight operation procedures.

Thermal vacuum testing is conducted in a large chamber that allows the lunar lander to experience conditions similar to what it will face during its journey through outer space including extreme temperatures in a vacuum environment. Initial test results indicated successful operation of power systems, guidance, navigation and control (GNC) equipment, radio communications, and thermal control of the lander while simulating an actual spaceflight. During testing in the chamber, ispace operators utillized the lander’s onboard radio to assess connections, send commands to, and receive telemetry from the lander, further simulating actual flight operations.

This lander will also carry a mini-rover, and will be launched by a Falcon 9 rocket. The company’s press materials don’t name a location for the lunar landing spot, though one must have been chosen. I suspect, as this mission is a precursor to Ispace’s first NASA lunar landing mission set for 2026, it will be sent to the same location as Ispace’s first Hakuto-R1 test mission, which got to within three miles but then crashed because sensors thought it was just above the surface and shut off the engines prematurely.
