Martian mesas made entirely of dry ice!

Dry ice mesas on Mars
Click for full image.

Time for an especially cool image! The photo to the right, taken on February 13, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and cropped and reduced to post here, shows some mesas on the south polar ice cap of Mars.

What makes those mesas cool (literally and figuratively) is that they are thought to be made up entirely of dry ice, part of the thin but permanent frozen carbon dioxide cap in the south. As explained to me by Shane Byrne of the Lunar and Planetary Lab University of Arizona, who requested this image from MRO,

[These mesas are] unusually thick compared to other dry ice mesas (a common landform in the residual ice cap). I only have the lower resolution laser altimeter data to go off for heights here (we may get a stereo pair next year), but from that it looks like 13 meters thick.

That’s about forty feet high, from base to top. In length, the largest mesa on the left is about a mile long and about 1,500 feet wide, on average. And it is made entirely of dry ice!

The red cross on the map below shows the location of these mesas on the south pole ice cap.

Today’s blacklisted American: New Apple hire fired immediately because other Apple employees considered his writings “unsafe.”

12:28 pm

The Bill of Rights cancelled at Facebook and Instagram
Doesn’t exist at Apple.

They’re coming for you next: Though Apple had actively recruited Antonio García Martínez and had reviewed his past work thoroughly before hiring him, the company fired him almost as soon as he started working for them because some of its other workers had put together a letter calling for his blacklisting because his published writings made them feel “unsafe.”

“Given Mr. García Martínez’s history of publishing overtly racist and sexist remarks,” the letter read, “we are concerned that his presence at Apple will contribute to an unsafe working environment for our colleagues who are at risk of public harassment and private bullying.”

All of this without even a hint that there’s ever been anything like such a problem at any of his workplaces.

The letter above, like the campaign against Martinez by hack press outlets like The Verge, includes a number of slanders and purposely false interpretations of what Martinez had written in his one published book, Chaos Monkeys, available on line from all ebook vendors and described on its Amazon page as

Screen capture from ULA’s live stream.

Capitalism in space: ULA successfully launched a Space Force military reconnaissance satellite using its Atlas 5 rocket. It also deployed two cubesats.

This was the first Atlas 5 launch in 2021. The satellite has now been deployed into its transfer orbit taking it to its final geosynchronous orbit.

The leaders in the 2021 launch race:

15 SpaceX
12 China
7 Russia
2 Rocket Lab
2 ULA

The U.S. now leads China 21 to 12 in the national rankings. Note also that though we are still six weeks short of the year’s halfway point, the U.S. is already more than halfway to its total from all of 2020, 40 launches. If this pace continues the U.S. has a good chance of reaching launch totals that were only routine during the mid-1960s, at the height of the beginnings of the space race.

NASA gives an American the seat on Dragon flight that it had been holding for Russian

10:15 am

NASA yesterday announced that it has added an American astronaut to the next manned mission to ISS, set for October.

NASA said that Kayla Barron will join the Crew-3 mission, launching on a SpaceX Crew Dragon spacecraft scheduled for launch no earlier than Oct. 23. Barron joins NASA astronauts Raja Chari and Tom Marshburn, and European Space Agency astronaut Matthias Maurer, who had been assigned to Crew-3 last December.

The Crew-3 mission will relieve the Crew-2 astronauts who arrived at the station on another Crew Dragon spacecraft April 24. The four Crew-3 astronauts will remain on the station for a six-month stay.

The space agency had been holding that seat open for a Russian, as part of its long term barter arrangement whereby in exchange for flying Americans on Soyuz capsules, Russia flies Russians on American spacecraft. That arrangement had been used repeatedly when the shuttle was flying, but since its retirement the U.S. has been forced to buy its seats on Soyuz as it had nothing to offer in exchange.

With the arrival of SpaceX’s Dragon capsule however NASA has been trying to get the Russians to renew that arrangement. And though an American, Mark Vande Hei, flew for free on a Soyuz last month, the Russians have as yet refused to assign their own astronaut to this upcoming October flight, despite months of negotiations. It appears NASA decided it could wait no longer, and filled the seat with its own astronaut.

In fact, the announcement by Roscosmos on May 13th that the next two Soyuz launches to ISS will carry two commercial passengers each means that Vande Hei cannot return on a Soyuz until next year. The seat he would have used to come home now must be used by these tourists, meaning his mission will now be extended to last for as much as a full year or more.

Unless of course NASA decides to bring him home on a Dragon capsule instead.

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.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

China rolls out rocket for next space station launch

10:00 am

The new colonial movement: On May 15th China rolled out the Long March 7 rocket that on May 20th will carry the first Tianzhou cargo freighter to the already launched core module of its space station.

Tianzhou-2 will carry 4.69 tons of cargo in a pressurized segment and 1.95 tons of propellant, according to the China Manned Space Agency (CMSA).

Meanwhile, the core stage, dubbed Tianhe, has successfully completed its on-orbit checkouts and has placed itself in the right orbit for the arrival of Tianzhou.

If all goes right with this cargo mission, China is targeting a June launch for the station’s first three-man crew, who will attempt to stay at the station for three months.

Do not expect much information to be released by China during these missions. Like the Soviet Union of old, and as they have been doing routinely since their space program began to gear up in the past decade, they will only make periodic terse announcements, all of which will contain only the most superficial of information. Only much later will more be learned, usually many years after the fact when its news value has vanished and it only concerns historians and space buffs.

Flash! SpaceX to use a NEW Falcon 9 1st stage!

9:48 am

Both side boosters landing during the 1st Falcon Heavy launch
Both side boosters landing during
the 1st Falcon Heavy launch

Capitalism in space: For the first time in since September 2020, SpaceX has delivered a new Falcon 9 1st stage to its Florida launch site in preparation for launch.

This new stage will be used on the June 3rd launch of a cargo Dragon freighter to ISS.

What is remarkable about this story is that it is news that SpaceX is using a new first stage. Not only have all of their fifteen launches in 2021 lifted off with used boosters, since November 2020 they have completed nineteen launches using only used boosters.

That’s 19 launches in only six months, all with previously flown boosters!

During that time the company’s Falcon rocket division has apparently dedicated its time in upgrading and building new Falcon Heavy 1st stage boosters, in preparation for the first Falcon Heavy launches since June 2019, set for July and October later this year. I suspect the focus has been an effort to upgrade the core booster so that it will be successfully recovered this time, something that did not occur on two of the first three Falcon Heavy launches in 2018 and 2019..

Texas: No masks, no restrictions, now no COVID deaths!

3:24 pm

Surprise! Surprise! Two months after lifting business restrictions and mask mandates, Texas reported yesterday no deaths linked to COVID.

Once again the fear-mongers were wrong. Biden called the officials in both Texas and Mississippi “neanderthals” for their decisions to end lockdowns and mask requirements. Others predicted a wave of deaths that would boggle the mind.

Instead, cases of COVID dropped quickly, to actually reach zero for the first time in fourteen months. Though I am sure there will be new coronavirus cases and deaths, that the numbers dropped after removing the stupid lockdowns and mask mandates is just another illustration of how failed a policy those lockdowns and mask mandates were.

Nor is any of this a surprise to anyone who has read this website for the past year. I have been saying from day one that the lockdowns were a terrible mistake, and that the mask mandates were not only useless but possibly very counter-productive. As another writer noted today, “The Neanderthals were right.”

Where is China’s Zhurong Mars rover?

2:13 pm

Where is Zhurong?

At this moment we do not have confirmation that China’s rover Zhurong landed safely on Mars. Assuming it did, the mosaic to the right, made from two images from Mars Reconnaissance Orbiter’s (MRO) context camera, shows that landing zone, with the white cross indicating the centerpoint of the suspected landing site, as leaked to the Chinese press back in October 2020.

The red boxes are the only two images released by China that were taken by its Tianwen-1 orbiter of this landing zone. The two white boxes show the areas covered by two of the seven or so photographs taken by MRO’s high resolution camera since that location was revealed. Below is a map showing all the images MRO has taken of this location.

Why no visual confirmation of the landing on Mars of China’s Zhurong rover?

12:03 pm

Despite more than 48 hours having passed since China announced the successful landing of its Zhurong rover on Mars in the northern lowland plain of Utopia Planitia, no images or data of any kind has been released by that nation or its space agency.

It is very possible that this is totally expected, since they have always said they will need about a week of checkouts before they rollled the rover off the lander and begin its operations.

At the same time, China has been very very creative with providing early images for all its planetary missions. For example, within hours of landing they had released images from their Chang’e-5 lunar sample return lander. Similarly, only hours after Chang’e-4 landed on the far side of the Moon with its Yutu-2 rover China released images.

They did the exact same thing when Chang’e-3 landed in 2013 with its Yutu-1 rover.

I can’t imagine they don’t have some cameras on the Mars lander to snap pictures of the horizon or the ground directly below. They might not, but if so the lack would be truly astonishing.

It is also possible China is holding the data close for any number of political reasons, though this doesn’t make much sense since the whole political point of these planetary missions is to sell China to the world.

The more time that passes with no confirmation data, the more it will appear that something is wrong. If this conclusion is incorrect, China needs to act now to dispel these doubts.

Today’s blacklisted American: Space Force officer fired for criticizing Marxism and condemning bigotry

11:12 am

Twitter's idea of debate
Show trials: What America’s Space Force apparently wants.

Blacklists are back and the military’s got ’em: Lt. Col. Matthew Lohmeier, a fourteen year veteran of the Air Force who became one of the first officers in the Space Force, has been fired by his superiors because he wrote a book criticizing Marxism and compounded that sin by repeating the criticisms, along with criticisms of the undeniable bigotry of critical race theory, on a public podcast.

From a military pr officer:

“This decision was based on public comments made by Lt. Col. Lohmeier in a recent podcast,” a Space Force spokesperson said in an email. “Lt. Gen. Whiting has initiated a Command Directed Investigation on whether these comments constituted prohibited partisan political activity.”

Lohmeier’s temporary assignment in the wake of his removal was not immediately clear. [emphasis mine]

In addition, Amazon has decided to shadow ban Lohmeier’s book, Irresistible Revolution.

Irresistible Revolution has debuted in a strong position and as of this writing, it is #2 and #3 in military policy on Amazon, despite the fact that within hours of Lohmeier being relieved of his command, the book was no longer searchable on the publishing giant’s website. Only a direct link to the book’s page works at this time. It is available at Barnes & Nobles and other online booksellers such as Hudson and AbeBooks.

Lohmeier notes that he wrote the book entirely on his own time. He also informed the military of its existence and offered to have them review it before publication. The Pentagon said such a review was not required.

So what exactly did Lohmeier say that made his superior, Lt. Gen. Steven Whiting, believe he was participating in “partisan political activity”? From the Military.com come article:

SpaceX launches 52 Starlink + 2 customer satellites

4:09 pm

Capitalism in space: SpaceX today successfully launched another 52 Starlink satellites along with two smallsat satellites.

They have put just under 1,700 Starlink satellites into orbit. The first stage completed its 8th launch, and the fourth in 2021, according to the SpaceX announcer. Let me repeat that: That’s four launches of the first stage in less than five months. The fairing halves were also flying on their second flight.

The leaders in the 2021 launch race:

15 SpaceX
12 China
7 Russia
2 Rocket Lab

The U.S. now leads China 20 to 12 in the national rankings.

Rocket Lab launch fails

9:22 am

Rocket Lab’s launch yesterday of its Electron rocket failed when the upper stage began tumbling right after stage separation and engine start.

This was the second Electron failure in twenty launches. The last, in July 2020, was also caused by a problem in the upper stage, though far less dramatic. In that case an electric failure caused the upper stage engine to shut down prematurely before it had reached orbit.

Though the launch was a failure, the recovery of the first stage as part of Rocket Lab’s effort to make it reusable appears to be proceeding as planned. According to the company’s statement:

Electron’s first stage safely completed a successful splashdown under parachute and Rocket Lab’s recovery team is working to retrieve the stage from the ocean as planned.

I have embedded below the fold the Rocket Lab live feed, cued to just before the failure. You can see that as soon as the upper stage fires it begins to tumble.

China’s Zhurong rover successfully lands on Mars

10:45 pm

The rover landing site for Tianwen-1's rover

The new colonial movement: China’s today successfully landed its Zhurong rover on the northern lowland plains of Mars dubbed Utopia Planitia.

China’s lander and rover began their descent to the surface at about 4:00 p.m. EDT (2000 GMT) by separating from the Tianwen-1 orbiter, which since March has been used to capture imagery of the targeted landing site for study. An aeroshell protected the stacked probes as they plunged into the atmosphere at 3 miles per second (4.8 km per second), generating tremendous heat in the process.

Once inside the atmosphere, while traveling at supersonic speeds, the spacecraft deployed a 2,150-square-foot (200 sq. meter) parachute to slow its approach to less than 328 feet per second (100 m per second). China based the canopy design on the parachutes it has used on Shenzhou missions to return astronauts to Earth.

Finally, the Tianwen-1 lander fired thrusters similar to the type on China’s Chang’e lunar landers to make the final descent. A laser range finder and a velocity sensor helped guide the craft as it hovered at about 328 feet (100 m) to identify obstacles and measure the slopes of the surface before touching down safely.

We don’t yet know the exact touchdown point. The image above is a mosaic of two wide angle photos from the context camera on Mars Reconnaissance Orbiter (MRO), with the white cross marking the spot previously leaked by the Chinese press as the landing site. The white box shows the area covered by the only high resolution MRO photo, as of October 2020. Since then MRO has taken a number of additional high resolution images of this area. The red boxes are the areas covered by the only two high resolution images released by China from its Tianwen-1 Mars orbiter

Note that the rover is actually not yet on the ground. It still sits on the lander. A ramp will be deployed and it will then roll down on the ground to begin what China says is a planned 90 day mission, with the most important data likely coming from the rover’s ground penetrating radar, looking for underground ice.

The flaking and cracked floor of a Martian crater

The flaking and cracked floor of a Martian crater
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on April 1, 2021 by the high resolution camera of Mars Reconnaissance Orbiter (MRO). It shows the central portion of the floor of an unnamed 5-mile-wide crater in northeast corner of Hellas Basin, the deepest large depression on Mars.

The latitude is 33 degrees south, where many glacier features have been identified, especially inside craters.

In this case, the cracked and flaked surface of this crater floor suggests what geologists call exfoliation, “the breaking off of thin concentric shells, sheets, scales, plates, and so on.” On Earth exfoliation generally refers to an erosion process seen on rock faces, though you can see it on other types of materials.

In this Martian crater we appear to be seeing the exfoliation of different ice layers, sublimating away at different rates as they are exposed to the Sun. The layers probably suggest different periods on Mars when snow was falling here, causing the glaciers to grow. The sublimation we see now suggest periods when this region was warmer and the ice was shrinking. Whether we are in such a period now is not yet determined by scientists.

Either way, the photo suggests at least two such cycles, though if we could drill down into this material we would likely find evidence of many more.

Below the fold is a global map of Mars, showing the location of this crater with a red cross in Hellas. The regions surrounded by white borders are areas where many glacial features have been found.

Today’s blacklisted American: The Spectator magazine, by Google’s YouTube and Vimeo

12:11 pm

The Bill of Rights cancelled at Facebook and Instagram
Doesn’t exist at Google, YouTube, or Vimeo.

They’re coming for you next: Simply because an interview by The Spectator with Trump lawyer John Eastman discussed the many indications of election fraud and vote tampering in the November election, both Vimeo and Google’s YouTube decided that the video needed to be banned, forever.

YouTube said that the video violated its policy on misinformation. When the Steamboat Institute attempted to post the video under a different title, YouTube removed it again and revoked Steamboat’s ability to post videos for a full week. Vimeo also removed the video, saying that they ‘do not permit content that seeks to spread false or misleading information about voting.’

Steamboat was finally able to upload the interview to the Canadian video platform Rumble. You can watch it here and decide for yourself if this video is as dangerous as Big Tech claims.

As usual for these big tech censors, they cite no specific examples of “false or misleading information” expressed during the interview. They just claimed it existed, and banned everything.

It is important to also understand that the interviewer, Amber Athey, repeatedly pressed Eastman about his statements and position. The goal was not to allow him to simply sell his position, but to provide the viewer a legitimate discussion of the facts, pro and con, and thus allow that viewer the ability to decide for themselves whether Eastman’s concerns about the election have some merit.

This however is not good enough for YouTube or Vimeo. And they banned this Spectator interview at the same time they allowed with no complaints far more egregious lying and misinformation being spread by Democrats and leftists on their platforms:

SpaceX in FCC filing outlines first orbital flight plan for Starship

9:40 am

The flight plan for Starship's first orbital flight
Click for full images.

Capitalism in space: This week SpaceX filed the flight plan for the first orbital flight of its Starship/Superheavy rocket, taking off from Boca Chica and landing in the Pacific Ocean near Hawaii.

The images to the right are from the filing, which also states:

The Starship Orbital test flight will originate from Starbase, TX. The Booster stage will separate
approximately 170 seconds into flight. The Booster will then perform a partial return and land in the Gulf of Mexico approximately 20 miles from the shore. The Orbital Starship will continue on flying between the Florida Straits. It will achieve orbit until performing a powered, targeted landing approximately 100km (~62 miles) off the northwest coast of Kauai in a soft ocean landing.

No date is listed as yet, though the filing suggests they are aiming for a launch before the end of the year. It also appears that though both Starship and Superheavy will make controlled vertical landings, both will target locations in the ocean. It could be that SpaceX plans to place its two refurbished oil rigs at both of those locations, but this is not stated in the filing.

Achieving this flight before the end of the year remains a serious hill to climb, though if any company could do it, SpaceX is the most likely.

Tampering and serious discrepancies found in Arizona election audit

4:00 pm

The audit of the more than two million votes cast in Maricopa County, Arizona, in November 2020 is not yet complete, but auditors in the past week have revealed that they have already uncovered significant evidence of tampering and major discrepancies that throw great doubt on the victory given to Joe Biden.

First, the auditors forced the county election board to admit that the voting machines were not protected by a password at the administrative level, thus allowing anyone to change anything on every machine, during the vote count.

That doesn’t prove fraud or election tampering, it only proves that it was amazingly easy for it to happen.

Second, it appears from further work that something very fishy was going on. The auditors for example have discovered that Maricopa County officials illegally tampered with the voter database records before turning them over to the auditors, including the deletion of an entire database.

Capitalism in space: Roscosmos, the government corporation that controls of all of Russia’s space industry, announced today that it will be flying two different commercial tourist flights to ISS, both occurring before the end of this year.

The first will take place in October.

Roscosmos [is] sending an actress and a director to the ISS in October with the aim of making the first feature film in space. The film, whose working title is “Challenge,” is being co-produced by the flamboyant head of Roscosmos, Dmitry Rogozin, and state-run network Channel One.

The second will take place in December, and will fly Japanese billionaire Yusaku Maezawa (the man who has already purchased a Moon mission on SpaceX’s Starship) and his assistant Yozo Hirano in a Soyuz capsule to ISS for twelve days.

Senate committee mandates NASA award 2nd lunar lander contract

9:25 am

More crap from Congress: A Senate committee has approved a new NASA authorization that requires the agency to award a second lunar lander contract — in addition to the one given to SpaceX — even though that authorization gives NASA no additional money to pay for that second contract.

This provision was inserted by senator Maria Cantwell (D-Washington). Washington state also happens to be the state where one of the rejected companies, Jeff Bezos’ Blue Origin, is located. I wonder how much cash Bezos’ has deposited in Cantwell’s bank account.

This provision not only does not give NASA any cash to build two lunar landers, what NASA dubs the Human Landing System (HLS), it forces NASA to violate other laws.

Company offers luxurious 3-day astronaut training vacations

9:02 am

Capitalism in space: For those considering spending millions to buy an orbital tourist flight from SpaceX, a new company, Orbite, is now offering for only $29,000 a three day high-end astronaut training vacation that will include a short zero-gravity flight on an airplane.

[CEO Jason] Andrews and Orbite’s other co-founder, French-born tech entrepreneur Nicolas Gaume, have set the schedule for astronaut orientation courses that’ll include virtual-reality simulations, a zero-G flight and a high-G flight — all designed to provide a taste of space without tying the participant down to a particular program.

The first session will take place Aug. 23-27 at La Co(o)rniche, a five-star boutique hotel on France’s Atlantic coast that’s owned by Gaume’s family. Three other sessions will be offered at the Four Seasons Resort in Orlando, Fla., starting on Nov. 11, Nov. 25 and Dec. 2. Each session is limited to 10 participants.

Zero Gravity Corp. and Europe’s Air Zero G by Novespace will fly the participants on airplanes that can provide measured doses of weightlessness, about 30 seconds at a time. Other subcontractors will put them in the cockpits of planes such as P-51 Mustangs or Extra 330LX’s, which can deliver multiple G’s of acceleration.

In essence these training sessions are nothing more than a dressed up expensive vacation, though surely unique.
None of this training will qualify someone to fly in space, but it will give potential orbital and suborbital customers a taste of what to expect, which should help them decide if they want to cough up the bigger bucks necessary for the real deal.

More delays for Webb telescope?

8:53 am

An issue with the fairing release on the last two Ariane 5 launches has not only paused use of that rocket since August 2020, it might cause another delay in the planned October 31, 2021 launch of the James Webb Space Telescope.

In a statement to SpaceNews, Arianespace acknowledged that “post-flight analyses conducted on two recent Ariane 5 launches have indicated the occurrence of a less than fully nominal separation of the fairing, however with no adverse impact on the Ariane 5 flights in question.”

The company did not elaborate on the problem, but industry sources familiar with the issue said that, on both the August 2020 launch and the previous Ariane launch in February 2020, the separation of the faring induced vibrations into the payload stack well above acceptable limits. Neither incident damaged any of the payloads, but raised concerns about the effect on future missions, including JWST.

Moreover, Arianespace has two Ariane 5 launches on its schedule that are supposed to launch before Webb. If those are delayed it puts a further squeeze on the Webb launch date.

Meanwhile, the final checkouts of the Webb telescope have been proceeding, including a successful test of the unfolding of the telescope’s segmented mirror.

After a more than decade of delays and budget overruns — raising this telescope’s budget from 1/2 billion to $10 billion — it appears that Webb’s final schedule delay might occur not because of the telescope but because of the rocket.

In addition, the issue at Arianespace appears to be seriously impacting that company’s ’21 launch schedule, having failed to launch any Ariane 5 rockets so far this year.

Rocket Lab launch on May 15 will attempt a second ocean recovery of 1st stage

2:16 pm

Capitalism in space: Rocket Lab’s next planned launch on May 15th will attempt a repeat of the ocean recovery of their Electron rocket’s 1st stage, as they did after a November 2020 launch.

The goal of such work is to help transition the two-stage Electron from an expendable vehicle, as it was originally designed, to a rocket with a reusable first stage. And inspection of the recovered booster from “Return to Sender” suggests that this vision is no pipe dream. “We are more kind of bullish on this than ever before,” Rocket Lab founder and CEO Peter Beck said during a teleconference with reporters on Tuesday (May 11). “We reentered on a very aggressive corridor, we had no upgraded heat shield, and we still got [the booster] back in remarkable condition.”

Indeed, some parts of that rocket will fly again; the propellant pressurization system from the “Return to Sender” first stage has been incorporated into the “Running Out of Toes” Electron [launching May 15th], Beck said. [emphasis mine]

The highlighted words are quite remarkable. As far as I know, SpaceX never reused any part of a Falcon 9 first stage that was recovered in the ocean.

Rocket Lab also hopes to reduce any damage further by using new equipment on their ship for getting the stage out of the water. In addition, they have added heat shielding to the stage that should also reduce damage during its fall back to Earth.

Finally, on the next flight or so they will test something they are calling a “decelerator,” designed to slow the stage down during that fall. They are not saying what this decelerator is, which suggests it is some form of new engineering.

If all goes right, they hope to make the first snatch by helicopter of a first stage before it hits the ocean sometime next year.

Martian glacial run-off?

1:46 pm

Mosaic of glacial runoff
For original images click here and here.

Today’s cool image provides us a glimpse at the carved canyons created when the mid-latitude glaciers on Mars were active in the past and slowly flowing downhill into the section of the northern lowland plains dubbed Acidalia Planitia.

The photo to the right is a mosaic of two images taken by the context camera on Mars Reconnaissance Orbiter and rotated, cropped, and reduced to post here. The mosaic shows a region at the very edge of Acidalia Planitia at latitude 43 degrees north.

Below is a close-up of the area in the white box, taken by MRO’s high resolution camera on February 28, 2021, as well as a global map marking the location of this image at the very edge of the glacier country found in the chaos terrain of Deuteronilus Mensae.
