A drainage gully on Mars?

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.

European Parliament member demands cancellation of launch deal with SpaceX

9:26 am

Christophe Grudler, a member of the European Parliament (MEP) has written a letter to the government-run weather satellite company Eumetsat, demanding that it cancel its decision on June 26, 2024 to use a Falcon 9 rocket rather than the Ariane-6 on its next launch.

In a letter headlined “Request to reconsider launch decision in favour of European strategic interests”, Grudler disputes the decision of EUMETSAT, the intergovernmental European Organisation for the Exploitation of Meteorological Satellites, to choose America rather than Europe for launching its new satellite. He argues it goes against the principle of giving preference to Europe, something the organisation denies.

“I am writing to urgently request that you reconsider the recent decision to allocate the MTG-S1 satellite launch to a non-EU launch provider, and instead await the results of the inaugural launch of Ariane-6, which was your first choice for this satellite,” the Liberal member of Parliament wrote in a letter to the board.

…Grudler’s requests are threefold: “Cancel the last Council decision regarding a specific launcher solution, Await the inaugural launch of Ariane-6 before making any final decisions for MTG-S1; Reaffirm your dedication to European strategic autonomy by supporting European launch solutions”.

Eumetsat’s decision was clearly a financial one. SpaceX charges much less than Ariane-6, and its Falcon 9 rocket is proven and launching routinely. Ariane-6 won’t have its first launch until next week, on July 9th.

Grudler’s demands are purely political, but since the EU has generally been run top-down, letting politics and power determine its policy, he could force a cancellation of the contract. In the short term this will help ArianeGroup, a partnership of the aerospace companies Airbus and Safran that own Ariane-6, while hurting Europe’s weather satellite capabilities. In the long run it however might aid the growth of Europe’s new competing rocket startups, as it will provide them a guaranteed market. At the same time, having a guaranteed market by government fiat tends to limit competition and thus raise costs.

It appears that some politicians in Europe are still not sold on capitalism and freedom.

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.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

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.

July 4 mid-day pause: 1776

Let’s celebrate Independence Day with the brilliant film version of the 1972 Broadway musical, 1776. It is not only great because of the wonderful music and witty dialogue, it is great because it actually captures quite accurately the real personalities of these Founding Fathers.

Repost: Why we really celebrate the Fourth of July

10:30 am

I posted this essay in 2022 on July 4th and reposted it last year as well. It needs to be reposted again today. As I noted last year, my hopes for the November 2022 election were not realized, and we have suffered by that failure the past two years. We now face an even more critical election in November 2024. I wonder if Americans might finally decide to vote to clean house. I am hopeful, but also recognize that my optimism has been proven wrong consistently for decades.

—————-
Why we really celebrate the Fourth of July

The Declaration of Independence

If you really want to know why the Fourth of July has been the quintessential American holiday since the founding our this country, you need only return to the words of the document that became public to the world on that day.

Below the fold is the full text of the Declaration. Read it. It isn’t hard to understand, even if the style comes from the late 1700s. Its point however is clear. Governments that abuse the rights of the citizenry don’t deserve to be in power. The most important quote of course is right near the beginning:

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.

That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed — that whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.

Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security. [emphasis mine]

What a radical concept — a nation founded on the principle of allowing its citizens to pursue happiness.

Right now, however, we have a federal government in America that more fits the description of King George III’s Great Britain in 1776 in the Declaration. The corrupt elitist uni-Party of federal elected officials and the federal bureaucracy in Washington has for too long run roughshod over the general population. If you take the time to read the full text of the Declaration, you will be astonished at the remarkable conceptual similarity between the abuses that Jefferson describes coming from Great Britain and the many abuses of power that are now legion and common by the uni-Party in Washington.

When November comes the American public will likely have its last chance to overthrow the political wing of the uni-Party, led by the Democratic Party. The Republicans are no saints, but at least that party contains within it many decent politicians who honor the Constitution, the rule of law, and the Bill of Rights. Many are right now campaigning on those ideals. Based on the past six years, we now know that no one in the Democratic Party honors those values. What they honor is blacklisting, racism, segregation, anti-American hate, and above all power. If they are not removed from office, they will ramp up that power, in league with quislings like Romney and Cornyn in the Republican Party, to further corrupt our Constitutional government.

These people do not like losing power. The longer they hold it, the more they will work to undermine the election system to make sure they do not lose. The corruption and election fraud in 2020 election was merely a dress rehearsal of what these goons will do if they have the chance next year.

In fact, November 2022 might very well be the last election that has any chance of producing legitimate results. Americans had better not waste this last chance.

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.

Survey: Major shift rightward in Israel since October 7

10:43 pm

According to a series of surveys taken from August 2023 through June 2024, the Israeli population shifted significantly rightward in Israel after the Hamas massacre on October 7, 2023.

The shift was not so much ideological — leftists still professed support for socialist policies — but mostly related to security issues and attitudes towards the Arabs living in Gaza and the West Bank. For example,

According to the Agam Labs survey, 52 percent of Jewish Israelis oppose the government’s wartime facilitation of humanitarian aid to Gaza, and just 30 percent support the policy—roughly the reverse of the numbers prior to Oct. 7.

Support for direct Israeli aid to and cooperation with the Palestinians has fallen even faster and farther, down to roughly one-fifth of the public in both cases.

One former leftist is quoted in the article as follows, “They can have aid in Gaza when they give us back our hostages. That’s how I feel,” she said. “I guess that makes me a right-wing extremist.”

I would say this survey proves Israel is the perfect example of a liberal who becomes a conservative after getting mugged.

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.

Pushback: Jury awards former BlueCross researcher almost $700K for firing her vindicatively for not getting the jab

12:10 pm

BlueCross BlueShield of Tennesse, eager to blacklist
…and now paying for it.

Bring a gun to a knife fight: A jury has now awarded Tanja Benton, a former BlueCross research scientist, $687,000 in back pay and punitive damages against BlueCross BlueShield of Tennessee for firing her vindicatively in 2021 after she asked for an exemption from getting the COVID jab due to religious concerns.

I call the firing vindicative because by all measures, the fact tell us it was so.

Hamill [Benton’s attorney] said Benton’s job rarely involved direct interaction with clients, with only 1% of her total annual working hours involving client interaction. In the lawsuit, Hamill said Benton “never performed any work or attended any meetings in medical facilities where patients were being treated” and “physical in-person interaction with co-workers was never a job requirement.”

Moreover, for nineteen months prior to her firing, Benton had done all her work remotely, as ordered by BlueCross itself due to the COVID panic. As noted in her lawsuit:

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:

70 SpaceX
29 China
8 Russia
8 Rocket Lab

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.

Democrats: You got what you asked for when the Supreme Court ruled presidents have absolute immunity for official actions

3:18 pm

Cry havoc and let loose the dogs of war!

As always, the Democrats have once again demonstrated their utter inability to reflect even slightly on the consequences of their actions.

On July 1, 2024 the Supreme Court, faced with an appeal from Donald Trump that claimed he as president should have immunity from prosecution when his political opponents gain power, ruled that yes, Trump is right, that presidents do have absolute immunity for their “official” actions while in office.

The majority opinion finds that presidents have absolute immunity for core constitutional powers and presumptive immunity for other official acts. This immunity does “not extend to conduct in areas where his authority is shared with Congress,” and unofficial acts taken while in office receive no immunity at all.

The court ruled that President Trump’s conversations with the acting attorney general were core conduct subject to absolute immunity. It also ruled that his conversations with the vice president about the counting of the votes were part of his official duties, thus subject to presumptive, but not absolute, immunity—finding that Judge Chutkan should now assess whether prosecution of these actions intrudes on the authority and functions of the executive branch, and prosecutors will have to rebut the presumption of immunity if so.

Since then Democrat politicians and pundits have been gnashing their teeth in horror, claiming that this ruling now allows presidents to do almost anything once in office, from assassinating their opponents to using the military to arrest and eliminate judges he or she does not like.

The irony here of course escapes the Democrats. First, hasn’t Biden and his Department of Justice and the FBI been doing a milder form of the same abuse of power in their lawfare against Trump and those who worked for him?

Second, this case would never have gotten to the Supreme Court in the first place if the Democrats had not started that lawfare campaign. By prosecuting Trump on numerous weak and sometimes utterly bogus charges, it forced the issue to the courts, which was then forced to rule.

The biggest irony of this whole issue is that the Democrats are right. » Read more

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

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.
