SpaceX launches 25 more Starlink satellites

SpaceX this morning successfully placed another 25 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California.

The first stage completed its 15th flight, landing on a drone ship in the Pacific.

Indian rocket startup Skyroot now shipping its Vikram rocket to launch site

The Indian rocket startup Skyroot has now finished assembling its Vikram-1 rocket, and is about to ship it to its launch site at the Sriharikota spaceport on the east coast of India.

At Sriharikota, the rocket moves into final assembly and a round of system checks before a launch window is locked in the coming months. This is the last stretch before liftoff. Countdown operations, testing and integration now shift fully to the launch site.

One of the company’s founders said the most critical testing has been completed, with launch campaign activities set to begin at the spaceport.

The company is presently targeting a launch in June. If Vikram-1 reaches orbit successfully, Skyroot would become the first Indian private company to design, build, and launch its own rocket, and would be well positioned to win launch contracts from smallsat companies, competing directly with Rocket Lab and its Electron rocket.

This success would also help accelerate the Modi government’s effort to transition from a space industry controlled entirely by its government space agency ISRO to a private industry run by competing indepedent companies.

Why is Sierra Space’s Dream Chaser spacecraft not ready for flight?

In a press release posted last week Sierra Space proudly announced that its Tenacity Dream Chaser mini-shuttle has completed its pre-launch ground vibration tests at the Kennedy Space Center in Florida, but instead of moving the mini-shuttle to a local facility where it could be integrated with its rocket for launch, the company announced it was shipping it back “to Colorado for final modifications and mission-specific upgrades.”

Normally when a spacecraft, satellite, or any payload passes these last ground tests, it is ready for launch, and it immediately begins integration onto the rocket that will carry it into space. That Sierra Space is not doing this strongly suggests Tenacity did not pass with flying colors, and that some issues were identified that need correction.

Note too that this spacecraft had been delivered for these tests in early 2024, and had been expected to pass them then and be launched that year. Instead, months passed with no word, then its launch was postponed indefinitely, and then NASA canceled Sierra’s contract to provide cargo to ISS.

Now, two years later Tenacity is still not ready for launch. Though the company says the ground tests are now complete, I suspect otherwise. I suspect there is some fundamental issue with the spacecraft that they are hiding because to reveal it would be devastating to Sierra’s public reputation.

Until we know more however this is pure speculation on my part. What we do know however is that this mini-shuttle has not done what was promised, and increasingly appears to be a lemon that will never do it.

Two launches today, by China and Russia

Both China and Russia completed launches today. First China put a Pakistani Earth observation satellite into orbit, its Long March 6 rocket lifting off from Taiyuan spaceport in north China. China’s state-run press made no mention of where the rocket’s lower stages, using very toxic hypergolic fuels, crashed inside China.

Next Russia launched a Progress cargo capsule to ISS, its Soyuz-2 rocket lifting off from Baikonur in Kazakhstan. The freighter will dock with ISS in two days.

Space Force issues twelve companies Golden Dome contracts worth $3.2 billion

As part of the first phase of development of the proposed Golden Dome defensive system, the Space Force revealed this week that it has awarded twelve companies contracts worth $3.2 billion to develop the first prototype designs.

The service awarded other transaction authority (OTA) agreements — worth up to a combined $3.2 billion — to the vendors in late 2025 and early 2026, according to a Space Systems Command press release. Under the contracts, the companies will develop prototypes of a space-based architecture that can shoot down enemy missiles after they’re launched.

The companies that received OTAs are Anduril, Booz Allen Hamilton, General Dynamics Mission Systems, GITAI USA, Lockheed Martin, Northrop Grumman, Quindar, Raytheon, Sci-Tec, SpaceX, True Anomaly and Turion Space Corp.

The twelve companies have very different capabilities, suggesting the Space Force is hoping to get a lot of different ideas and proposals that will not only give it options but could also provide it multiple methods for destroying in-coming missiles.

Soyuz launch site destroyed at French Guiana

As promised, the Soyuz-2 launch site at France’s French Guiana spaceport was destroyed in a controlled explosion yesterday.

I have embedded video of the explosion below.

The remaining infrastructure at the site—including the assembly and testing complex, railway lines, liquid oxygen storage facilities, and fueling systems—will be transferred to MaiaSpace, a French startup affiliated with Arianespace. The company plans to reuse up to 80% of the existing infrastructure for its own launch vehicle program.

MaiaSpace is not “affliated with Arianespace.” It is a wholly owned subsidiary of ArianeGroup, the company that makes the much larger rocket Ariane-6. The company hopes MaiaSpace’s smaller Maia rocket can capture some of the smallsat business presently owned by Rocket Lab and SpaceX.

The Russians had almost a dozen launches scheduled from this launchpad, worth more than a billion dollars in revenue, when Putin decided to invade the Ukraine in 2022. Russia immediately became a pariah to the rest of the work. That revenue instantly vanished and the companies found other launch providers.

Europe meanwhile gave control of French Guiana back to France, which owns it. France in turn has now been leasing out the unused launchpads there to new rocket startups. Though some pie-in-the-sky academics lobbied to preserve the Soyuz launchpad for “historical reasons”, the French had no desire to do so. Better to make money.

New data says interstellar Comet 3I/Atlas IS different from comets in our solar system

Using spectroscopic data from the ALMA telescope in Chile, astronomers have determined that interstellar comet 3I/Atlas is enriched in deuterium (sometimes called “heavy water”), with quantities as much as 30 times that found in ordinary solar system comets and 40 times that found in Earth’s oceans.

You can read the peer-reviewed paper here. From its abstract:

3I/ATLAS shows a deuterium enrichment exceeding Earth’s ocean value by more than a factor of about 40 and typical Solar System cometary values by more than a factor of about 30. The elevated deuterium enrichment points to water that formed under colder, less irradiated conditions and from less thermally processed material, consistent with an origin in a planetary system that formed under different physical and chemical conditions than our own.

In other words, the conditions in which Comet 3I/Atlas’ solar system formed were very different from those when our own solar system formed.

This conclusion is wonderful, but it raises more questions than it answers. Since we do not know how old the comet is, nor do we really know where it came from, there is little else we can glean from this result, other than it proves the conditions when solar systems form can vary widely.

Blue Origin opens (secretly) its first foreign office, in Luxembourg

Blue Origin last week opened its first office in another country, in Luxembourg, though the company made no official announcement and the fact only became public when a Luxembourg official mentioned it at a conference in Colorado.

In an unexpected twist, the opening of the European HQ was eventually announced on 15 April 2026, not by the company but by Luxembourg Economy Minister Lex Delles – and not at the Grand Duchy office, but on his visit to the 41st annual Space Symposium, held in Colorado Springs in the US.

Blue Origin’s office on the capital’s Avenue de la Liberté had, in fact, opened right on schedule, Tim Collins, the company’s Vice- President of Global Operations and Supply Chain, told the Luxembourg Times in interview on Wednesday.

…Asked why Blue Origin declined to confirm its opening schedule until April, despite media follow-up requests, Collins said there was no cover-up: the company merely wanted to have something to show off before officially opening. The process has been roughly on schedule throughout, he stressed.

The office will work with Blue Origin’s European customers as well as manage its foreign supply chain, not just in European but globally.

China launches another “set of test satellites promoting internet technology”

China today successfully placed what its state-run press described merely as “a new set of test satellites promoting internet technology”, its Long March 2D rocket lifting off from its Xichang spaceport in southwest China.

No word on where the rocket’s lower stages, using very toxic hypergolic fuels, crashed inside China. The state-run press did add this about the payloads:

These satellites will be mainly used to carry out technology tests and verifications, including direct satellite-to-phone broadband connectivity and space-ground network integration.

Ted Nugent – Cat Scratch Fever

An evening pause: Performed live 1979. I had never heard of this real disease caused from an infected cat scratch, until my knee surgeon warned me about it prior to surgery. As our two cats are gentle and have never scratched me, and are also indoor cats, I wasn’t concerned.

Then Diane sent me this song. Heh. You learn something new every day.

Hat tip Diane Zimmerman.

Note: At present I have almost no suggestions for evening pauses, not even from my regular contributors. If you’ve suggested pauses in the past you know the drill and have the guidelines. If you haven’t done so before but want to, just mention this fact in the comments below. I will contact you with the guidelines. Don’t include your suggestion in your comment or then I can’t really use it.

Isaacman before Congress: Speaking the truth to power

Jared Isaacman at House hearing yesterday
Jared Isaacman at House hearing yesterday

There has been a lot of attention given by the propaganda press to the testimony yesterday by NASA administrator Jared Isaacman before the House Science Committee, with almost all of that coverage focused on two issues, Trump’s proposal to cut NASA’s budget significantly, and the public statement by Isaacman that two Lunar Gateway modules were delivered “corroded.”

On the corrosion issue, much of the press focused on whether Isaacman’s statement is true (contractors are denying it). I instead was struck by how little pushback there was overall from Congress about Isaacman’s proposal to cancel Gateway entirely. In two hours of testimony, only one congressman brought it up, and even he did not challenge Isaacman’s decision very strongly.

Put simply, it really didn’t matter whether these modules were corroded or not. Congress is not going to challenge Isaacman on this decision. Some politicians might use it in fund-raising letters or at press events as a hammer to win votes or donations, but when it comes time to approve NASA’s budget, they are willing to accept Isaacman’s overall judgment. Gateway will be gone.

As for the budget cuts, I was also struck by the lack of hard opposition from Congress, despite reporting from the propaganda press (like this story) suggesting the cuts were rejected outright. Though repeatedly Isaacman was questioned about those cuts — especially from Democrats — repeatedly he fought back hard, to good effect. He supports Trump’s cuts and does not want more money, because in reviewing NASA’s budget and recent actions, he has found there is ample cash available in Trump’s reduced budget by simply shutting down bad or duplicative projects and focusing his resources more effectively.

The only threatened program that seemed to generate any passion from Congress was Trump’s effort to eliminate NASA’s education STEM program. “We need this program to inspire kids!” they would say. Isaacman would bluntly respond “No we don’t,” noting that NASA issues millions in education grants outside that program (making that program duplicative and unnecessary), and that the best way NASA can inspire kids is to actually fly missions, not send money to some bureaucratic program. Isaacman wants to use that money to make building the lunar base more likely.

Over and over again Isaacman pulled the rug out from under this big-spending congress critters by simply pointing out the truth to them, with one exchange with Zoe Lofgren (D-California) quite typical. She clearly was opposed to Trump’s cuts and wanted to challenge any cancellations being put forth. To do so, however, she wanted Isaacman to provide more detailed information about those cuts. Issacman said sure, I’m glad to provide you everything you want, but then added this:

ESA: Full-sized model of its Space Rider reusable capsule is ready for landing drop tests

Artist rendering of Space Rider in orbit
Artist rendering of Space Rider in orbit. Click for original.

My heart be still! The European Space Agency (ESA) yesterday announced that a full-sized model of its Space Rider reusable capsule is now ready for landing drop tests from a helicopter.

The avionics – Space Rider’s ‘brain’ – were installed in the second week of March. This computer hosts the Guidance, Navigation and Control algorithms that will steer the parafoil, adapting to the wind – including any gusts– to guide Space Rider to a soft landing.

Roughly the size of a mini-van, the drop-test model is a full-size stand-in for the 4.6-m long reentry module, Space Rider lands on skis with the landing gear permanently open on this model as the mechanism is not part of the drop test.

To get an idea how unserious ESA is, we need to review this project’s overall schedule. This reusable capsule concept — which appears to be a variation of either Varda’s returnable capsule or Boeing’s X-37B — was first tested by ESA in 2015. By 2017 the agency was promising it would be flying commercially by 2025. A decade later and they have not yet begun testing a full scale spacecraft.

And the development pace now is glacial. Last summer ESA did helicopter drop tests of just the “brain” and parafoil. It is now going to do those drop tests again, a year later, with this full scale model. Expect another year to pass — at a minimum — before it tries another set of helicopter drop tests, this time with the first actual Space Rider capsule.

At this pace, Space Rider might fly by 2030, maybe. In the meantime, expect at least a half dozen private capsules to fly commercially, for profit. Following Varda’s success investment capital has poured into this industry. All will go from a blank sheet of paper to a flight model in less than five years.

And even if ESA finally gets Space Rider operational, it has established some very complex rules about who can use it commercially, rules so complex I predict few will be interested.

Russia launches the smallest version of its Angara rocket

Russia today successfully launched the smallest version of its Angara rocket, dubbed Angara-1.2, from its Plesetsk spaceport in northeast Russia, placing a number of classified payloads into orbit.

Russia’s state-run press released almost no information about this launch, partly because of its military nature but also because it has discovered recently that the Plesetsk spaceport is within range of Ukrainian drones, with one attack causing a launch to be scrubbed.

China picks two Pakistanis to train for a future Tiangong-3 mission

As part of its Soviet-style propaganda effort to promote its space program, China yesterday announced the names of the two Pakistanis who will train for a future short mission to its Tiangong-3 space station.

The agency said in a statement that Muhammad Zeeshan Ali and Khurram Daud will come to China soon as reserve astronauts for training. After completing all training and evaluations, one of them will participate in a space mission as a payload specialist, becoming the first foreign astronaut onboard the Tiangong space station.

This flight is part of Pakistan’s partnership with China in its International Lunar Research Station (ILRS) project to build a lunar base, created by China to counter the U.S.’s Artemis Accords alliance. Pakistan will also fly a small demo rover on China’s Chang’e-8 unmanned lunar mission, scheduled presently for a 2029 launch.

While the American alliance has now signed 63 nations covering most of the world’s major nations, only thirteen nations and about eleven eleven academic or governmental bureaucracies — mostly third world — have joined China.

This Chinese international manned mission mirrors largely what the Soviets would do during the Cold War, flying someone from one of its captured countries to garner international propaganda points. Do not expect these astronauts to do much concrete work. During the Soviet era, the Russians would joke that these foreign astronauts would all get “red hands” disease, caused whenever they tried to touch anything and a Russian astronaut would then slap their hands, saying firmly “Don’t touch that!”

Rocket Lab launches satellites for Japan’s space agency JAXA

Rocket Lab today successfully placed eight smallsats for Japan’s space agency JAXA, its Electron rocket lifting off from one of its two launchpads in New Zealand.

Because all of JAXA’s rockets are presently grounded due to technical failures, Japan’s space agency has had to turn to Rocket Lab. In fact, these eight satellites were originally supposed to launch on JAXA’s Epsilon-S rocket, which remains grounded after an explosion during a static fire test. There have been no updates on the status of Epsilon-S since December 2024.

Rocket Lab was also supposed to do a suborbital hypersonic test flight yesterday out of Wallops Island in Virginia, using the first stage of Election in its HASTE suborbital configuration. As this is a test for the War Department, little information is generally released. This video from a distance confirms the launch apparently took place, but whether it was a success or not remains unknown. That Rocket Lab’s announcers did not tout its success either before or after today’s JAXA launch — as they have routinely done in the past — suggests something might have gone wrong, though this too is pure speculation.

Curiosity looks at a small crater as it climbs Mount Sharp

Antofagasta crater
Click for full resolution. Click here, here, and here for original images.

Cool image time! The panorama above, created from three pictures taken by the right navigation camera on the Mars rover Curiosity (see here, here, and here), takes a look at a small relatively fresh crater on the slopes of Mount Sharp. From an update from the rover’s science team yesterday:

At the beginning of the week, Curiosity arrived right on target on the rim of the 10-meter (33 feet) “Antofagasta” crater. The crater looked fresh and deep as we had hoped with a nice well-defined rim that didn’t look too eroded, but the bottom of it turned out to be filled with dark rippled sandy material that covered up the most interesting rock layers. There were a few rock exposures just above the sand cover that seemed like they might have been deep enough to have been sheltered from space radiation between the time their sediments were deposited and the crater-forming impact, but reaching them from the rim would have put the rover at such an awkward angle that we wouldn’t have been able to deliver the sample to the instruments.

Overview map
Click for interactive map.

It’s possible that we might have been able to get into a better position by instead placing the rover on the rippled crater fill, but the chance that the rover could get stuck in all that sand made it much too high a risk. We also looked at the nearby blocks in case they could have been ejecta from the crater, but since all the rocks visible in the crater wall looked very similar to each other, there wasn’t a good way to tell which ejecta blocks might have come from the deeper layers of the crater. Because of this, the team decided against attempting to drill in or around the crater.

The overview map to the right provides the context. The blue dot marks Curiosity’s location when the pictures above were taken. The yellow lines roughly indicate the area covered by the panorama. The red dotted line marks the future planned route, the white dotted line the rover’s actual travels.

Note the flat rocks in the foreground of the panorama, all part of the crater’s rim. Each looks like a large flat paving stone that was very precisely shattered into numerous tiny pieces, all about the same size. Very strange. On Earth you’d assume some craftsman had laid these small pieces down like tiles, but of course, that couldn’t have happened on Mars.

European startup Atmos raises €25.7 million to develop its orbital research capsules

The European startup Atmos announced today that it has raised an additional €25.7 million [$30 million] as part of its ongoing commercial program to develop its Phoenix orbital research capsules that will fly in space for several months — where products can be produced in weightlessness — and then return those products safely to Earth.

The funding will support an initial three-vehicle PHOENIX 2 fleet, the launch of ATMOS WORKS for governmental and defence customers, and development of PHOENIX 3, the company’s next-generation orbital return vehicle.

The round is co-led by Balnord and Expansion, and joined by Keen Defence and Security. The European Innovation Council (EIC) participates through its Accelerator programme via blended financing, combining grant and equity components. Additional investors include OTB Ventures, High-Tech Gründerfonds (HTGF), APEX Ventures, Seraphim, Faber, E2MC, Kirch Ventures, Lennertz & Co., Mätch VC, MBG Baden-Württemberg, and Tech Horizons.

Since the American company Varda successfully demonstrated there was money to be made flying these small recoverable capsules, investment capital has poured into this industry. In the U.S. Varda, Inversion Space, and Sierra Space, have raised money for doing such orbital work. In Europe, The Exploration Company in France, Atmos in Germany, PLD in Spain, Genesis in Croatia, and Space Cargo in Luxembourg have also raised capital.

At this moment, however, only Varda has successfully launched and recovered a capsule.

Northrop Grumman lost $71 million from its bottom line because of its solid-fueled booster failures

In its most recent financial statement, Northrop Grumman admitted it took a $71 million charge due to nozzle failures on two of its solid-fueled boosters, dubbed GEM 63XL, during two different launches of ULA’s Vulcan rocket.

In a statement about its first-quarter financial results, the company said its Space Systems division recorded a $71 million “unfavorable adjustment” to earnings at completion on its GEM 63XL booster “associated with a launch anomaly that occurred during the first quarter.”

The GEM 63XL solid-fuel booster is used on United Launch Alliance’s Vulcan Centaur rocket. On a Feb. 12 launch, one of four boosters shed debris about 65 seconds after liftoff. The “observation,” as ULA termed it initially, did not affect the success of the USSF-87 mission, placing its payload into its planned geosynchronous orbit.

ULA later called the incident a “significant performance anomaly” with the booster that it would investigate before returning Vulcan to flight. The vehicle has not launched since then.

A similar incidence took place during an earlier Vulcan launch, with the rocket’s core stage and the remaining undamaged boosters getting the payload into the proper orbit. The continuing problem however has now grounded Vulcan, though the military is considering using it for some small payload launches, without the GEM strap-on boosters.

As a result, the Pentagon has already shifted several launches from ULA to SpaceX, costing ULA a significant amount of revenue. In addition, Vulcan’s grounding will impact the launch of Amazon’s Leo internet constellation, which had a major contract with ULA to get its Leo satellites into orbit.

Jordan to sign the Artemis Accords

According to a press announcement tonight from NASA, Jordan will sign the Artemis Accords on April 23, 2026 at NASA headquarters in Washington, DC.

NASA Administrator Jared Isaacman will host Ambassador Dina Kawar of the Hashemite Kingdom of Jordan and U.S. Department of State Principal Deputy Assistant Secretary for Oceans and International Environmental and Scientific Affairs Ruth Perry for the ceremony.

Jordan becomes the 63rd nation to sign the accords. It also joins Bahrain, Oman, Saudi Arabia, and the United Arab Emirates from the Arab Middle East. While it is certainly wise to not trust any nation controlled by Islam, having these nations allied with us in space will help mitigate the worst aspects of their religion. That they are also joining a space alliance that includes Israel is another indication that they are realizing that their future is better aligned with Israel than against it.

The full list of nations in this American space alliance is as follows:

Angola, Argentina, Armenia, Australia, Austria, Bahrain, Bangladesh, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Cyprus, Czech Republic, Denmark, Dominican Republic, Ecuador, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Israel, Italy, Japan, Jordan, Latvia, Liechtenstein, Lithuania, Luxembourg, Malaysia, Mexico, the Netherlands, New Zealand, Nigeria, Norway, Oman, Panama, Peru, Poland, Portugal, Romania, Rwanda, Saudi Arabia, Senegal, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Thailand, the Philippines, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

Japan to do test launch of its H3 rocket in June

Japan’s space agency JAXA is now planning a test launch on June 10, 2026 of its H3 rocket, carrying a dummy payload only in order to test the changes it has made in the rocket after a failed launch in December 2025.

The failure of the eighth H3 rocket was likely caused by an adhesion problem in the satellite mounting structure, which led it to break apart during flight, according to an investigation by JAXA. Similar issues were found in other units, prompting the space agency to fix them so the components can maintain their structural integrity.

In the June launch, a dummy satellite will be mounted on the test vehicle to collect data and verify the effectiveness of the measures. For future launches of actual satellites or space probes, JAXA plans to review the mounting structure design to reduce the risk of failure.

In other words, the method for attaching the payload to the rocket at some points failed, so that the satellite separated prematurely. The June launch will be to test a new mounting system.

Posting has been light the last few days as I deal with recovery from knee surgery.

Two launches by SpaceX

In the past two days SpaceX completed two more launches. The first, yesterday morning, placed 25 more Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California. The first stage completed its 8th flight, landing on a drone ship in the Pacific.

Then tonight SpaceX launched a GPS satellite for the Space Force, its Falcon 9 rocket lifting off from Cape Canaveral Space Force Station in Florida. The first stage completed its 7th flight, landing on a drone ship in the Atlantic. That drone ship, “Just read the instructions,” is now being shifted to support Starship operations, and will no longer be used for Falcon 9, after supporting 155 first stage landings. What it will do in connection with Starship has not been made clear. The two fairing halves completed their 2nd and 3rd flights respectively.

The Space Force had originally intended to launch this satellite on a ULA Vulcan rocket, but a month ago it shifted the contract to SpaceX because of the nozzle problem that has plagued two different ULA Vulcan launches. Because of this shift, the time from contract award to launch was the quickest by SpaceX for the Space Force.

NASA’s IG: With only Axiom building NASA’s future spacesuits, the agency’s lunar program faces great scheduling risk

Axiom's two spacesuits being tested underwater
Axiom’s two spacesuits being tested underwater in October 2025.
Click for original.

According to NASA’s inspector general’s report today [pdf] on the state of NASA’s effort to create new spacesuits for use by its astronauts on future space stations as well as in its Artemis lunar program, the planned schedules for the lunar landing and those stations are threatened because the agency presently has only one contractor, Axiom, building new suits, and has not established any spacesuit standardization rules should it want to issue contracts to others. From the report’s conclusion:

While NASA is taking steps to mitigate schedule risk, it must also contend with the unique risks inherent to a single-provider environment until future competition is introduced. … If Axiom cannot satisfy its contractual requirements in a timely or cost-effective manner, then NASA could be forced to continue using the problematic EMUs throughout the life of the ISS and significantly adjust its lunar plans. [EMUs are the complex suits presently used on ISS, and would not work well for any lunar landing mission.]

While xEVAS [the new suit concept] is flexible enough to allow for additional providers, doing so may not help the Agency meet its more immediate Artemis goals. Critically, NASA must address existing design and safety risks resulting from the lack of standard requirements for spacesuits to be compatible with various lunar spacecraft and assets.

As shown by the photo above, the development of Axiom’s spacesuit has been proceeding, and seems likely to be available for next year’s Artemis-3 Earth orbit test mission. At the same time, it is still behind schedule, a fact that has been mitigated because NASA’s entire Artemis program is equally behind schedule.

The report lists three commercial companies that might be able to provide alternative suits, and thus some redundancy, as shown by the image below.

Hubble looks at the Trifid Nebula again

Trifid Nebula as seen by Hubble
Click for original image.

Cool image time! The picture to the right, cropped to post here, was taken by the Hubble Space Telescope and released today. It shows a small section of the Trifid Nebula, located about 5,000 light years away.

This location has been imaged numerous times in the past by Hubble. The area shown illustrates some fundamental aspects of stellar and nebula formation. The dark area in the lower right is a thick dust cloud. Several energetic O and B supermassive stars are out of view at the top. The radiation from these stars (indicated by the blue), is hitting that dust cloud and literally destroying it. It appears that the foreground “horn” exists because a larger object is blocking the radiation, allowing dust to survive in the background.

I have no explanation for the background “horn”.

This new image was taken in parallel with an image of the entire Trifid Nebula, taken by the new Rubin Telescope in Chile. Though Rubin cannot see with the same resolution as Hubble, its image is quite worthwhile viewing.
