Cool image time! The picture to the right, reduced and sharpened to post here, was taken by the Hubble Space Telescope and released today. It shows a galaxy only 30 million light years away, making almost our neighbor. From the caption:

NGC 3489 has an active galactic nucleus, or AGN. The AGN sits at the center of the galaxy, is extremely bright, and emits radiation across the entire electromagnetic spectrum as the black hole devours material that gets too close to it.

This lenticular galaxy is a Seyfert galaxy, which is a class of AGN that is dimmer than other types of AGNs. They generally don’t outshine the rest of the galaxy, so the galaxy surrounding the black hole is clearly visible. Other types of AGNs emit so much radiation that it is almost impossible to observe the host galaxy.

That active nucleus is the bright dominate sphere at the galaxy’s center, large enough to overwhelm a large percentage of the rest of the galaxy. Its existence and dominance suggests that this galaxy is aging, and is beginning the transition from a spiral to an elliptical. In fact, its arms have already mostly vanished, and there is at present little star-formation on-going.

Irish startup lobbies for Irish spaceport

9:26 am

According to an official from the startup SUAS Aerospace, Ireland is an ideal location for the creation of a new spaceport.

Mr O’Halloran, who is now vice chairman of Irish space company SUAS Aerospace, said space vehicles could be launched from Ireland for telecommunications, environmental monitoring, or medical experiments.

…He later told the Irish Examiner: “There are loads of companies in Europe that need to have a facility of a launch pad, or a spaceport, and by and large they are all heading towards the Azores. The UK is now starting to set up spaceports, but they are now outside the EU. Ireland is ideal as a launching site.”

This Irish company’s focus, according to its website, is “…to build a leading European Space Port providing flexible commercial satellite launch facilities with provision for engine and rocket testing.” And it wants to do it in Ireland. O’Halloran’s speech was an effort to gin up both private and government support for the project, including a commitment of the Irish government to provide it the land it needs for such a site.

There are already three spaceports under development within the EU, in Spain, Norway, and Sweden, all of which at the moment are for suborbital rockets exclusively. Ireland’s location could make it a better choice for orbital launches, as it has many more options for flight paths over the Atlantic without crossing land.

Suborbital rocket explodes four seconds after launch in New Mexico

9:15 am

An UP Aerospace suborbital rocket exploded yesterday only four seconds after launch in New Mexico, destroying a number of private and NASA science and commercial payloads.

An UP Aerospace rocket, 20 feet tall and carrying a NASA payload, exploded moments after liftoff today. The unfortunate event not only affected the NASA TechRise Student Challenge payloads but also delayed a poignant tribute to the late NASA astronaut, Phillip K. Chapman, and chemist Louise Ann O’Deen.

The rocket was set to launch the cremated remains of Chapman, NASA’s first Australian-born American astronaut, finally granting him his long-awaited journey to space.

Chapman and O’Deen’s remains were payloads from the commercial company Celestis. The thirteen NASA payloads were part of its TechRise Student Challenge program for 6th to 12th grade students.

Exploring just one small corner of Valles Marineris, Mars’ Grand Canyon

2:11 pm

One corner of Valles Marineris
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on February 19, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the many many many layers that are found in the cliffs of Valles Marineris, the largest known canyon in the solar system and far far larger that Earth’s Grand Canyon.

The elevation difference between the red dots is just under 4,000 feet. Yet that high point is still more than 7,000 feet below the rim of the canyon, more than thirty miles to the south. And the lower dot is still about 18,000 feet above the low point in this side canyon of Valles Marineris, about thirty miles away to the northeast.

In other words, in sixty miles from rim to floor the canyon at this location drops about 25,000 feet, only 4,000 feet less than the height of Mount Everest. Compare that with the Grand Canyon’s slopes, which drops in eleven miles about 5,000 feet, beginning at the main south rim lookout at the start of Bright Angel trail.

Environmentalists sue FAA, demanding it shut down Boca Chica and Starship

12:10 pm

Starship/Superheavy at T+4:02, just after the self-destruct command was issued
Starship/Superheavy at T+4:02, just after the self-destruct command
was issued on April 20, 2023. It also appears to be the fate of SpaceX’s
entire Boca Chica operation, if the environmental radicals get their way.

A group of environmental groups as well as a non-profit corporation calling itself the Carrizo/Comecrudo Nation of Texas, Inc, today filed a lawsuit against the Federal Aviation Administration FAA), demanding it shut down SpaceX’s Boca Chica facility and block all further Superheavy/Starship launches.

You can read the lawsuit here [pdf]. Its essence is contained in these two paragraphs:

The area surrounding the SpaceX facility at Boca Chica is a biologically diverse and essential habitat area for many species, including federally protected wildlife and animals that are considered sacred to the Carrizo/Comecrudo People, such as the critically endangered ocelot. The SpaceX facility is smack in the middle of publicly owned conservation, park, and recreation lands, including a National Wildlife Refuge, two State Parks, a State Wildlife Management Area, and a State Coastal Preserve. These lands are of extraordinary conservation value for a range of federally and state lists wildlife and other protected species such as migratory birds. Bird species from both the Central and Mississippi flyways converge there, making it an essential wintering and stopover area for migratory birds as they move north and south each year.

SpaceX activities authorized in the FONSI/ROD [the environmental reassessment issued last year] have and will adversely affect the surrounding wildlife habitat and communities. In addition to harm from construction activities and increased vehicle traffic, rocket launches result in intense heat, noise, and light pollution. Furthermore, the rocket launches and testing result in explosions which spread debris across surrounding habitat and cause brush/forest fires — including one that recently burned 68 acres of adjacent National Wildlife Refuge. The FAA calls these explosions “anomalies,” but in fact they occur frequently, with at least 8 over the past 5 years. FAA acknowledged that many more such “anomalies” are expected over the next 5 years. The U.S. Fish and Wildlife Service has found that prior SpaceX rocket explosions harmed protected wildlife and designated habitat in violation of the Endangered Species Act (ESA).

In other words, rockets and launch sites should never be placed inside wildlife refuges, because such activity is detrimental to wildlife.

A more false statement cannot be made. Under this conclusion the launch facilities at Cape Canaveral, which have been operating in the middle of a wildlife refuge now for more than six decades, should be shut down immediately. All the wildlife there must certainly be dead!

Galaxies without end

9:44 am

Galaxies without end
Click for full image.

Cool image time! The picture to the right has been significantly reduced but also significantly sharpened to post here. It was taken by the Hubble Space Telescope as part of a recent survey of “jellyfish” galaxies, galaxies located in galaxy clusters where there is a large concentration of galaxies whose combined gravity and intergalactic environment acts to pull material or “tendrils” out from the galaxy.

Rather than crop the image to focus on that single large central jellyfish galaxy, I have instead sharpened the much-reduced full photo to bring out clearly the number of surrounding galaxies. There is only one Milky Way star in this picture, the object with the four diffraction spikes in the lower-right. Every other dot is a galaxy, many of which can be seen to be very strangely shaped in the original full resolution image. In fact, I strongly recommend you click on the picture to explore that original image, just to see the variety of galaxy shapes.

The point of this picture today however is not to illustrate the wide variety of galaxies that can exist, but to underline the vast and largely incomprehensible scale of the universe. The large galaxy is thought to be 650 million light years away, which means it took light traveling at 186,000 miles per second that many years to get here. The surrounding galaxies are also all tens to hundreds of millions of light years from each other. Yet, their combined gravity, almost infinitesimal in strength, is enough to warp the shape of each.

We understand these numbers and facts intellectually, but do we understand them in reality? I think it is difficult, even if you work hard to come up with a scaled comparison. For example, it took nine years for the New Horizons spacecraft to get from Earth to Pluto, a distance of about 4.5 light hours. And New Horizons was the fastest traveling probe ever launched, moving at 36,400 miles per hour when it left Earth. Yet, this distance is nothing compared to the distance between these galaxies.

The vastness of existence really is beyond our comprehension. That we try to comprehend it speaks well of the human desire to achieve the impossible.

Viasat drops launch contract with Ariane-6

9:03 am

With SpaceX’s Falcon Heavy having just completed the first of three launches for Viasat’s new geosynchronous constellation of communication satellites, the satellite company has announced that it is cancelling its launch contract with Ariane-6 for the third launch.

The decision means the launch contract is up for grabs for the third ViaSat 3 internet satellite, the last of a three-satellite constellation Viasat is deploying to provide global broadband connectivity from space.

Viasat announced in 2018 it selected SpaceX, United Launch Alliance, and Arianespace to each launch one ViaSat 3 satellite, awarding launch contracts to three industry leaders.

The ULA launch, on its Atlas-5 rocket, is still scheduled for either late this year or early next.

The development of Ariane-6 however is years behind schedule. Furthermore, Arianespace has given priority on Ariane-6 to all of the ESA launches that formerly were going to be launched on Russian Soyuz rockets, further delaying Viasat’s launch.

For Viasat, the delays have become unacceptable, and it has now opened that third launch to bidding. Though both ULA’s Vulcan and Blue Origin’s New Glenn rockets could do the job, neither is operational either. It appears SpaceX’s Falcon Heavy is the only rocket available and is therefore almost certain to get the contract, a conclusion further confirmed by the timing of this announcement, just prior to that successful Falcon Heavy launch.

SpaceX’s Falcon Heavy completes second launch in 2023

9:08 pm

SpaceX today successfully placed a Viasat communications satellite into geosynchronous orbit using its Falcon Heavy rocket, completing its second launch in 2023. Also on board were two smallsats.

The company did not recover either side booster or the core stage in order to give the rocket the maximum lift to put Viasat’s satellite into its proper orbit. With this flight, the two side boosters had successfully completed eight and three missions during their lifespan.

The leaders in the 2023 launch race:

28 SpaceX
16 China
6 Russia
3 Rocket Lab
3 India

American private enterprise now leads China 31 to 16 in the national rankings, and the entire world combined 31 to 28. SpaceX by itself trails the entire world, including American companies, 28 to 31.

Musk press conference on Starship/Superheavy launch

8:51 am

Yesterday Elon Musk held an hour-long audio press conference with a number of space reporters, broadcast over youtube. I have embedded that conference below, for those of my readers who wish to hear what Musk had to say, in his own words.

The key take-aways from Musk:

  • The launch was about what he expected
  • They will be ready to launch again in about two months
  • The debris “was really just basically sand and rock so it’s not toxic at all … it’s just like a sandstorm, essentially”
  • The biggest issue is making sure the flight termination system functions better.
  • The next flight will be a repeat, with the main goal getting to stage separation
  • He gives them an 80% chance of making orbit this year

When asked about obtaining the permit for that next flight, Musk side-stepped the question. It remains to my mind the largest obstacle for meeting his schedule.

Radar antenna on Europe’s JUICE probe to Jupiter stuck

8:27 am

European Space Agency officials revealed yesterday that the 52-foot radar antenna on its JUICE probe to Jupiter has failed to deploy as planned, and that they are attempting to shake what they think is a small pin free that is in the way.

Engineers suspect a tiny pin may be protruding. Flight controllers in Germany plan to fire the spacecraft’s engine in hopes of shaking the pin loose. If that doesn’t work, they said they have plenty of time to solve the problem.

Juice, short for Jupiter Icy Moons Explorer, won’t reach the giant planet until 2031. It’s taking a roundabout path to get there, including gravity-assist flybys of Earth and our moon, and Venus.

The radar antenna is needed to peer beneath the icy crust of three Jupiter moons suspected of harboring underground oceans and possibly life, a major goal of the nearly $1.8 billion mission. Its targets include Callisto, Europa and Ganymede, the largest moon in the solar system.

If this antenna cannot be freed, it will prevent JUICE from doing one of its prime missions.

SpaceX successfully launches Falcon 9 from Cape Canaveral

5:39 pm

SpaceX today successfully used its Falcon 9 rocket to put a SES communications satellite into orbit.

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

The company also attempted to complete a second launch just a little more than three hours later from Cape Canaveral, but the countdown of the Falcon Heavy rocket aborted just 59 seconds prior to liftoff. No word on what happened, though the company has another launch window beginning around 7:30 pm Eastern time tomorrow. If successful it would be the second Falcon Heavy launch in 2023, using two side boosters flying their eighth and third flights respectively. Because of the fuel needs of the payload, neither the side boosters or the core stage will be recovered.

The leaders in the 2023 launch race:

27 SpaceX
16 China
6 Russia
3 Rocket Lab
3 India

American private enterprise now leads China 30 to 16 in the national rankings, and the entire world combined 30 to 28. SpaceX by itself trails the rest of the world, including other American companies, 27 to 31.

Pushback: FIRE sues school for banning students from wearing “Let’s Go Brandon” shirts

2:35 pm

The evil shirt Tri-County Area School officials banned
The evil shirt Tri-County school officials banned

Bring a gun to a knife fight: Because school officials at Tri-County Middle School in Michigan forbid two students from wearing sweatshirts that said “Let’s Go Brandon” on their fronts, even as they permitted other students to wear shirt promoting the queer agenda, the Foundation for Individual Rights and Expression (FIRE) has filed a lawsuit against the schools.

In Feb. 2022, two Tri County Middle School students wore sweatshirts to school with the phrase “Let’s Go Brandon,” a political slogan critical of President Biden with origins in a more profane chant. Even though the political slogan is widely used — multiple members of Congress used it during floor speeches — an assistant principal and a teacher ordered the boys to remove the sweatshirts. However, administrators allowed students to wear apparel with other political messages, including gay-pride-themed hoodies.

The incident is part of a pattern of political favoritism by the school district. When the school district relaxed the dress code for field day, a school administrator ordered a student to stop wearing a Trump flag as a cape, but permitted other students to wear gay pride flags in the same manner.

Glacier layers on the border of Hellas Basin

Dipping glacial layers
Click for original image.

Cool image time! The picture to the right, cropped and reduced to post here, was taken on February 21, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as “dipping layers”, referring specifically to the mesas with the terraces on their western flanks.

The layers obviously signify past cycles of geological events on Mars. That the terraces are only on one side of the mesas suggests that they are tilted, with the downhill grade to the east.

These layers however pose several mysteries. First, why are they located so specifically in only certain places of this region? It appears that the layered terrain is only found in the lower hollows and valleys. Why?

Second, why are they tilted at all?

Maxar’s Worldview-3 satellite snaps in-orbit pictures of Landsat-8 satellite

10:13 am

Landsat-8 as seen by Maxar's Worldview-3
Click for original short movie.

Using its high resolution imaging capability, mostly designed to do Earth observations, Maxar engineers took a series of pictures of NASA’s Landsat-8 satellites when the two satellites happened to pass reasonably close to each other. One of those pictures, a screen capture from the short movie that Maxar created, is to the right.

Maxar Technologies’ Worldview-3 satellite has delivered images of NASA’s Landsat 8 spacecraft from ranges of between 56 miles (91.4 kilometers) and 80 miles (129.9 km), showing clear details of the powerful Earth-observation satellite. A still image reveals the 29.5-by-1.3 foot (9 by 0.4 meters) solar array powering Landsat 8, as well as distinct science payloads on the satellite’s 9.8-foot-long (3 m) bus, or main body.

Both satellites are in similar, near-polar orbits, with Worldview-3 circling around 381 miles (613 km) above Earth, while Landsat has a higher altitude of 437 miles (703 km).

Though very cool, this image was taken by Maxar to sell the company’s capabilities to future customers. The military wants the ability to do surveillance of foreign satellites, while satellite companies often need to get such imagery of their satellites to assess their condition. Maxar has now proven it can provide this service to both.

Big space Raytheon shifts gears to compete in the new space market

9:55 am

Capitalism in space: Raytheon, a traditional big space contractor focused mostly on winning military contracts, has decided to shifts gears from what has in recent years been a failed effort to compete for major contracts direct from the military and instead offer its capabilities to other commercial space companies.

This decision was fueled largely by the approach of the military’s Space Development Agency (SDA) to commercial contracts.

SDA’s approach to buying satellites from multiple prime contractors under fixed-price contracts is “revolutionizing space acquisitions,” [Raytheon official David Broadbent] said. The agency has been a “huge disrupter,” he said.

“Let’s call it what it is,” Broadbent added. “Raytheon and many of our traditional defense primes were constructed around sole source classified cost-plus businesses, and five to seven-year acquisition cycles.” Those markets no longer exist, he said. “So we’ve had to take a very hard look at ourselves … and drive to a far more efficient model of producing capabilities.”

In other words, Raytheon has recognized that the government golden goose of unlimited cost-plus contracts is gone, and that the company’s over-priced habits under those contracts made it difficult for it to compete against new startups designed to be efficient, low-cost, and quick on their feet.

By marketing its available products directly to other satellite and rocket companies, Raytheon can avoid the long contract competitions of the government, and make sales more effectively. As it does this it will also have time to restructure the company itself, trimming it down and making it more efficient so that it can better compete for government contracts at a later time.

Raytheon’s change is the result of the SDA essentially accepting many of the recommendations put forth in my 2017 policy paper, Capitalism in Space (a free pdf download). Rather than have the military the designer and builder of a few big and expensive satellites (also very vulnerable to attack), it is now the customer buying constellations of many small and cheap satellites from many private companies. Such smallsat constellations are much more difficult to disable by hostile powers.

With the federal bureaucracy gleefully sharpening its knives to shut down Boca Chica, SpaceX should quickly shift Starship/Superheavy operations to Florida

1:12 pm

Superheavy still going strong, shortly after Max-Q
Superheavy still going strong, shortly after Max-Q

The results of the spectacular test launch last week of SpaceX’s Superheavy/Starship heavy lift rocket was predictable in almost all ways.

First, everyone knew that it was highly unlikely that the launch would do everything intended. This was the first time ever that SpaceX had fired all 33 Raptor-2 engines at the base of Superheavy, at full power. It was the first time ever that this firing took place with Starship stacked on top. It was the first time ever that the entire stack was fueled. It was the first time ever that this rocket — the world’s most powerful (twice as powerful as the Saturn-5 and about three times more powerful than SLS) — had every launched.

The number of unknowns were gigantic, which was exactly why SpaceX needed to do the launch. The company’s engineers needed to find out what they didn’t know about Superheavy in order to refine their engineering so that Superheavy will be more likely for success in its next launch. They also needed to find out what such a launch would do to their preliminary launchpad, in order to refine its engineering as well so that future launches could take place with little or no damage.

Thus, it is not surprising that there were surprises. The most significant was the actual amount of success. Superheavy functioned far better than anyone could have dreamed, retaining flight control through max-q and then flying for almost three minutes before Starship failed to separate and the entire stack lost control and had to be destroyed. Most of its engines worked, though discovering the reasons for the handful that failed will be a prime question in the subsequent investigation.

The second unsurprising thing about this launch is the reaction of the federal bureaucracy, run by Democrats and the Biden administration. It has quickly moved in to squelch any further launches at Boca Chica, likely for a considerable time. The FAA immediately initiated its own investigation while grounding all further launches from Boca Chica. The Fish & Wildlife Service has now begun detailing, almost gleefully, the amount of ground damage the launch caused, including ripping out the concrete base below the rocket and flinging chunks of debris hundreds of feet away as well as depositing a cloud of sand dust on everything up to 6.5 miles from the launchpad.

This quote however is significant, and tells us the real truth:

If global warming doesn’t kill us the fog will!

Shipping routes
Illustration showing the distance and time saved by going north
through the Arctic Ocean

A new report published by the American Geophysical Union, and touted by it though a press release today, says that while the melting Arctic Ocean icecap — caused by human-caused global warming — will make shipping more convenient, that shipping will be hindered by increased fog — caused by human-caused warming.

Arctic sea ice has been shrinking for decades. That loss has opened shipping channels in the Northwest Passage and the Northern Sea Route, allowing even non-icebreaker vessels to skip the time-consuming Panama and Suez Canals farther south. But as the ice recedes, cold air is exposed to more warm water, and warm vapor condenses into fog in those new passages. Hidden chunks of ice already pose risks to vessels making their way through foggy, low-visibility routes.

Astronomers discover 25 more repeating fast radio bursts, doubling the number known

10:18 am

Using a ground-based radio telescope in Canada that scans the northern sky each night, astronomers have discovered another 25 repeating fast radio bursts (FRBs), doubling the number that was previously known.

One surprising aspect of this new research is the discovery that many repeating FRBs are surprisingly inactive, producing under one burst per week during CHIME’s observing time. Pleunis believes that this could be because these FRBS haven’t yet been observed long enough for a second burst to be spotted.

The cause of FRBs still remains unsolved. The knowledge of specific repeating FRBs however will go a long way to figuring out this mystery, because other telescopes will be able to better observe later bursts, knowing when they are expected to occur.

SpaceX and Canadian phone company Rogers sign deal

10:04 am

SpaceX and the Canadian phone company Rogers Communications yesterday announced that they have signed an agreement to provide satellite-to-phone communications to customers throughout Canada.

Rogers and SpaceX will offer satellite-to-phone technology in Canada using SpaceX’s Starlink low earth orbit satellites and Rogers national wireless spectrum. The companies plan to start with satellite coverage for SMS text and will eventually provide voice and data across the country’s most remote wilderness, national parks and rural highways that are unconnected today.

This deal makes SpaceX now a direct competitor to OneWeb, as it is apparently structured comparable to how OneWeb operates. Up until now, SpaceX has been almost exclusively marketing to individuals, who connect up to Starlink directly. OneWeb meanwhile provides its service to large ground-based customers who then sell their network — enhanced by OneWeb capabilities — to individuals or small businesses. Because of this difference in approach, the two companies were selling their wares to different markets, making the competition less intense.

SpaceX with this deal is copying OneWeb’s approach almost exactly, which means the competition for satellite internet communications is now going to heat up considerably. For users of the internet, this is the best thing that could happen.

Engineers extend Voyager-2’s life by tapping into reserve power supply

9:54 am

Engineers have begun using a backup power supply on the Voyager-2 spacecraft — launched in 1977 and presently traveling in interstellar space — in order to extend the life of one of its five instruments one additional year.

To help keep those instruments operating despite a diminishing power supply, the aging spacecraft has begun using a small reservoir of backup power set aside as part of an onboard safety mechanism. The move will enable the mission to postpone shutting down a science instrument until 2026, rather than this year.

The solution is only temporary, as the end of the mission is inevitable as its radioisotope thermoelectric generator (RTG) was only designed to provide power for about a half century (!). As time passes its power supply slowly declines, forcing engineers in recent years to shut down other systems to allow the science instruments to operate. That all the other systems on both Voyager-1 and Voyager-2 remained operational until the end of their RTGs tells us how well these spacecraft were built by their 1970s creators.

Assuming this works, engineers will do the same thing on Voyager-1 sometime next year. In both cases, however, power from the RTGs will likely run out entire sometime in the next 5-10 years, ending the missions.

Czech Republic to sign Artemis Accords

9:39 am

In a press release today describing the planned signing ceremony, NASA today revealed that the Czech Republic is going to sign the Artemis Accords on May 3, 2023, becoming the 24th nation to join this American-led alliance in space.

The full list of signatories so far: Australia, Bahrain, Brazil, Canada, Columbia, Czech Republic, France, Israel, Italy, Japan, Luxembourg, Mexico, New Zealand, Nigeria, Poland, Romania, Rwanda, Saudi Arabia, Singapore, South Korea, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.

The accords, bi-lateral agreements between each nation and the U.S., were designed during the Trump administration to emphasize the rights of private investors in space and thus do an end-around of the Outer Space Treaty. Under the Biden administration it is no longer clear if that remains the goal. The existence of a signed alliance led by the U.S. and the capitalistic west however gives the U.S. the political force to protect those rights, assuming the American government is interested in the future in doing so.

It has also created a kind of bi-polar competition with the alliance of nations signing on to China’s projects in space. That alliance so far only includes China, Russia, and Venezuela, but we should expect several nations once part of the former Soviet Union, such as Kazakhstan, as well as other former communist block nations, such as North Korea, to sign up at some point. I would also expect Iran to join also.
