Phantom Space orders more than 200 rocket engines from Ursa Major

9:58 am

Hadley engine from Ursa Major

Capitalism in space: The smallsat startup rocket company Phantom Space today announced it has ordered more than 200 rocket engines from the rocket engine company Ursa Major.

The order includes Ursa Major’s 5,000-Pound Thrust Hadley engines and the new 50,000-pound thrust Ripley engines. By using Ursa Major’s Hadley engines, Phantom’s Daytona rocket is slated for orbital launch in 2023, just three years after Phantom Space was formed. Under the terms of the agreement, Ursa Major will supply hundreds of its Hadley engines in different configurations including ground test and upper-stage vacuum variants, as well as numerous Ripley engines for planned upgrades to the Daytona vehicle.

The CEO of Phantom Space, Jim Cantrell, gave me a tour of its facility here in Tucson only three weeks ago, during which I took the picture above of a Hadley engine being tested and prepared for further static fire tests.

Cantrell had been the founder of Vector, his earlier failed attempt to create a smallsat rocket company. He clearly has not let that failure stop him.

NASA to conduct second SLS launch dress rehearsal in June

9:47 am

In announcing a press conference later today about the status of NASA’s SLS rocket, the agency revealed it now plans to conduct a second SLS launch dress rehearsal in June.

NASA’s SLS rocket and Orion spacecraft arrived back at Kennedy’s Vehicle Assembly Building April 26 after a 10-hour journey from launch pad 39B. Since their arrival, teams have worked to replace a faulty upper stage check valve and repair a small leak within the tail service mast umbilical ground plate housing. The teams also have been performing additional checkouts while the spaceport’s supplier of gaseous nitrogen makes upgrades to their pipeline configuration to support Artemis I activities.

We will likely find out NASA’s new launch schedule for the rocket today.

China’s Long March 2D rocket launches 8 satellites

9:43 am

China today used its Long March 2D rocket to place eight Earth observation satellites into orbit as part of a larger constellation.

The Jilin-1 constellation, now consisting of 50 Earth observation satellites since its first launch in 2015, is China’s first-ever commercial remote-sensing satellite system. The system is operated by Chang Guang Satellite Technology Corporation, also known as Charming Globe, a commercial spinoff of the Changchun Institute of Optics, Fine Mechanics, and Physics in the northeast Chinese city of Changchun.

The constellation is planned to consist of 138 satellites by 2025, and the satellites will be orbiting at 535 km altitude above Earth. The constellation, featuring types of satellites with different capabilities, will ultimately be capable of revisiting any point on Earth every ten minutes, with an interim thirty-minute capability being achieved with sixty satellites in orbit.

China claims the data from this constellation will be for commercial use. Don’t be surprised however if its primary customer turns out to be China’s military.

As the rocket launched from one of China’s interior spaceports, its first stage crash landed in China. No word on whether it used parachutes or grid fins to control that landing.

The leaders in the 2022 launch race:

17 SpaceX
14 China
6 Russia
3 Rocket Lab
2 ULA

The U.S. still leads China 25 to 14 in the national rankings, with the U.S. leading all other nations combined 25 to 23.

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.

A quake south of Starship’s prime landing sites on Mars

1:31 pm

The lowlands south of Starship's prime landing site
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on February 23, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Though it shows the largely featureless northern lowland plains of Mars, it is particularly interesting for two reasons.

First, according to the photo’s label this scarp/ridge is apparently near a quake detected by the seismometer placed on Mars by the lander InSight, located about a thousand miles to the southwest. Though no information of the strength of this quake is available, it is likely to have been a small and weak one, interesting mostly because it indicates some small underground instability or a recent small impact on the surface. The image favors the former, as it shows no obvious recent features of change. What it does show is one very intriguing flow feature draping the scarp. As the location is at 34 north latitude in a region where scientists have found a lot of evidence of water ice very close to the surface, the flow could very well be glacial in nature, though dismissing a lava origin would be a mistake.

The second reason this location is of interest is what lies relatively nearby, as shown in the overview map below.

Pushback: Computer repairman who exposed Hunter Biden’s laptop sues media for slandering him

11:53 am

Adam Schiff, a pathological slanderer and liar
Any media that blindly repeats anything out of this guy’s mouth
risks getting sued for slander

Fight back twice as hard: The owner of the computer repair shop, who legally uncovered the laptop that belonged to President Joe Biden’s son Hunter Biden and exposed significant evidence of corruption by both, has now filed a multi-million dollar defamation lawsuit against CNN, Politico, the Daily Beast, and Congressman Adam Schiff (D-California).

John Paul Mac Isaac was highlighted in a blacklist column in March, noting how his entirely legal effort to expose extensive corruption by Joe Biden and his son prior to the election caused him to be harassed, threatened, and driven to bankruptcy. While he lived in hiding because of the physical threats against him, Isaac also found it impossible to get unemployment insurance because of stone-walling by the Delaware unemployment department, stone-walling that only ended when Isaac wrote of letter of complaint to the state’s junior senator.

Isaac’s nightmare began when Democrats like Schiff began spreading lies against him, suggesting without any evidence that he was a treasonous Russian agent and had even obtained the laptop illegally. Mainstream media outlets acting as Democratic Party operatives immediately republished those lies as if they were true, despite the reality that only a tiny amount of due diligence would have revealed them to be lies.

An earlier lawsuit by Isaac against Twitter was thrown out by the courts, leaving him with about $175K in legal bills. This new lawsuit however is now possible because of new sponsorship.

Fish & Wildlife documents now reveal its objections to SpaceX Boca Chica facility

9:32 am

We’re here to help you! Documents obtained by CNBC under a Freedom of Information request have revealed the specific objections of Fish & Wildlife that has helped delay the approval of the FAA’s environment reassessment of SpaceX’s Boca Chica facility for Starship launches.

SpaceX must take steps to track and mitigate its impact on endangered species and their habitat in order to gain approvals for testing and commercial launches of its Starship Super Heavy lift-launch vehicle in Boca Chica, Texas, according to documents from the U.S. Fish and Wildlife Service obtained by CNBC.

The documents, released by the federal agency in response to a Freedom of Information Act request, show that recent declines in an endangered bird species, the piping plover, have already been correlated with SpaceX activity at the South Texas facility.

The documents also reveal that SpaceX is, for now at least, reducing the amount of energy it plans to generate at a utility-sized natural gas power plant on the 47.4-acre launch site there.

According to a lawyer from the radical environmentalist organization the Center for Biological Diversity who was interviewed for the article, Fish & Wildlife’s demands are not tremendously restrictive, and might actually allow the project to go forward, since they appear to only require SpaceX to “monitor affected animal populations carefully, limit construction and launch activity to specific seasons or times of day and night, and use shuttles to reduce vehicle traffic of workers on location.”

I see it differently. I think Fish & Wildlife bureaucrats are struggling to come up with reasons to block SpaceX. They know that decades of data in Florida prove that rocket launches have no negative impact on wildlife. To claim such a thing in Texas is thus not justified. They are trying to do it anyway.

South Korean smallsat rocket startup to launch first suborbital test flight

9:18 am

Capitalism in space: A new South Korean smallsat rocket startup company, Innospace, is now planning its first suborbital test launch in December, launching a Brazilian military payload from that country’s Alcântara Space Center.

The 16.3-meter, single-stage test rocket is a precursor to the company’s planned commercial satellite launcher Hanbit-Nano, a two-stage small satellite launcher designed to carry up to a 50-kilogram payload to a 500-kilometer sun-synchronous orbit. The first stages of the two rockets are powered by a 15-ton-thrust hybrid rocket engine that uses liquid oxygen and paraffin-based propellants. Hanbit-Nano’s upper stage is equipped with a 3-ton hybrid engine, according to the Sejong-based company’s website.

“If the upcoming test launch is successful, we will start preparing for a test launch of Hanbit-Nano,” Innospace spokesperson Kim Jung-hee told SpaceNews.

The company has so far raised almost $28 million in private investment capital. It also has an agreement with Norway to launch its rockets from there.

Since South Korea’s government has its own rocket program, it will be interesting to see which succeeds first in getting into orbit.

Old Russian Proton rocket engine explodes in orbit, creating more space junk

9:11 am

According to tracking data from the Space Force, an old Russian Proton upper stage engine, originally launched in 2007, broke up on April 15, 2022, creating a small cloud of new space junk in a highly elliptical orbit.

These Proton upper-stage ullage motors are known as SOZ motors, and there are currently 64 of them in Earth orbit, McDowell tweeted. The acronym is short for “Sistema Obespecheniya Zapuska,” which translates roughly as “Launch Assurance System,” he said.

“The SOZ motors don’t use up all their propellant when they fire. And they have an unfortunate tendency to go bang years or decades later, leaving a bunch of debris in highly elliptical orbit. At least 54 SOZ motors have now exploded,” McDowell tweeted.

The SOZ motor that just blew up had been racing around Earth in a highly elliptical path, getting as close as 241 miles (388 kilometers) and as far away as 11,852 miles (19,074 km), McDowell said in another tweet, noting that “the debris will take quite a while to reenter.”

“So — this debris event was predictable and is well understood; still very unfortunate,” he wrote. [emphasis mine]

The highlighted words suggest a certain irresponsibility on the Russian’s part. If these upper stage engines are abandoned with fuel still on board, why doesn’t Russia use that fuel to fire the engines to de-orbit them safely, especially as the engines have a tendency to eventually blow up and cause space junk? There might be complex technical reasons, but I suspect the real reason is pure laziness on Roscosmos’ part. No one ever bothered to think about it.

ESA: ExoMars will likely be delayed till ’28 at the soonest

9:03 am

An official of the European Space Agency (ESA) at a May 3rd science meeting announced that the launch of its ExoMars rover will likely be delayed until 2028 at the earliest because of the partnership breakup with Russia due to its invasion of the Ukraine.

Russia had been providing both the launch rocket as well as the lander on Mars.

Speaking at a May 3 meeting of NASA’s Mars Exploration Program Analysis Group (MEPAG), Jorge Vago, ExoMars project scientist at ESA, said he doubted a new lander could be ready by 2026. “It is theoretically possible, but in practice we think it would be very difficult to reconfigure ourselves and produce our own lander for 2026,” he said. “Realistically, we would be looking at a launch in 2028.”

Launching in 2028 could pose technical challenges for ExoMars. One trajectory would get the rover to Mars relatively quickly, but have it arrive just a month before dust storm seasons starts at the preferred landing site. An alternative trajectory would require traveling for more than two years to each Mars, but get the rover there six months before dust storms start.

“We have been trying very hard to convince the engineering team that the dust storm season is not death,” Vago said. “We should concentrate on making the rover more robust and able to weather a dust storm.”

There are other issues. The rover will need new radioisotope heating units, or RHUs, to provide power, since Russia will no longer providing them. If the U.S. provides, the launch for security reasons will have to take place in the U.S., which means the launch provider will have to be American.

The delay to ’28 also could cause the ExoMars rover mission to be completely changed, repurposed to become part of the sample return mission that the ESA and NASA are partnering to bring back the cached samples that Perseverance is gathering. If so, this repurposing might delay its launch to Mars even further.

Today’s blacklisted American: College fires director of its free speech institute for advocating free speech

1:32 pm

No free speech allowed at St. Olaf College
No free speech allowed at St. Olaf College.

The new dark age of silencing: David Anderson, the president of St. Olaf College in Minnesota, has removed the director of the school’s Institute for Freedom & Community, Edmund Santurri, because Santurri apparently encouraged too much free speech by inviting a wide range of speakers to lecture at the institute.

The lecture that appeared to draw the most objections was by Peter Singer, who has expressed controversial views about disabled people. An appearance by John McWhorter — who has argued some anti-racism initiatives go too far in stifling debate — was also reportedly controversial.

Singer has for decades often advocated in favor of abortion and even infanticide. McWorter meanwhile opposes the racist principles of critical race theory. To put it mildly, these speakers indicated the sincerity of Santurri’s effort to bring a wide range of political thought to St. Olaf.

When Anderson removed Santurri, he explained his reasons were because the lectures arranged by Santurri had “created a new enemies of the Institute.” Anderson also justified the action because he had received complaints from the college’s board of regents as well as others at the college.

Biden’s NASA administrator slams the cost-plus contracts he endorsed when he was a senator

12:48 pm

Bill Nelson, Biden’s NASA administrator and a former Democratic Party senator from Florida, made it clear during his testimony before a subcommittee of the Senate Appropriations committee today that he condemns cost-plus contracts and no longer wants to use them for any NASA project, even though he demanded NASA use such contracts when he was a senator.

Nelson was asked what, in his opinion, was the biggest threat to NASA’s goal of landing humans on the Moon by 2025. Nelson responded that the agency needed competition in its program to develop a Human Landing System. In other words, he wanted Congress to support NASA’s request for funding to develop a second lander alongside SpaceX’s Starship vehicle.

But Nelson didn’t stop there. He said Congress needs to fund this lander contract with a fixed-price award, which only pays companies when they reach milestones. This contracting mechanism is relatively new for the space agency, which traditionally has used “cost-plus” contracts for large development programs. Such awards pay contractors their expenses, plus a fee. “I believe that that is the plan that can bring us all the value of competition,” Nelson said of fixed-price contracts. “You get it done with that competitive spirit. You get it done cheaper, and that allows us to move away from what has been a plague on us in the past, which is a cost-plus contract, and move to an existing contractual price.”

The significance of Nelson’s remarks is that it bluntly signals that the Biden administration has now wholly bought into the ideas I put forth in Capitalism in Space. Nelson wants NASA to be a customer that buys what it needs from the private sector, and to do it as inexpensively as possible. He also wants to encourage competition by allowing that private sector to own and control what it builds.

In the past, a new administration would have abandoned the policies of the past administration. Instead, the Biden administration is accelerating the Trump administration’s policy of encouraging private enterprise and eliminating cost-plus contracts.

The future of the American space industry appears bright indeed.

This statement by Nelson also indicates that the future of SLS is now very precarious, especially because it is being built almost entirely on cost-plus contracts. Any serious failure could kill it. And even if its next launch succeeds, further launches hang now by a very thin political thread. And the more success private space has, the thinner that thread will become.

Viasat once again demands government block its competitor Starlink

9:50 am

In a letter to the FCC submitted on May 2, 2022, Viasat once again demanded the government block the deployment of SpaceX’s full 30,000 Starlink satellite constellation.

SpaceX shouldn’t be allowed to greatly expand its Starlink network while light pollution issues surrounding its deployed satellites remain unresolved, Jarrett Taubman, Viasat vice president and deputy chief of government affairs, said in a letter to the regulator.

While calls for a thorough environmental review that Viasat made for Starlink’s current generation of satellites in December 2020 were largely rejected, Taubman said SpaceX’s plan to grow the constellation by seven times “would have significant aesthetic, scientific, social and cultural, and health effects on the human environment on Earth.”

In other words, rather than try to compete with SpaceX, Viasat wants the government to squelch that competition. Though Viasat’s previous complaints have been rejected entirely, there is no guarantee that the Biden administration will continue to reject them. Recent evidence suggests instead that it will instead use this complaint as another opportunity to limit SpaceX’s operations, for political reasons.

Meanwhile, the only possible harm to Earth the full Starlink constellation might do is cause a limited interference in ground-based astronomy. Since astronomers have made so little effort to get their telescopes into orbit, above such interference, few should sympathize with them. If anything, Starlink should be the spur to get all of its telescopes off the ground and into space. Astronomers will not only avoid light interference from Starlink, they will get far better data without the atmosphere smearing their vision.

Zhurong travels another 1,300 feet

9:35 am

Overview map

UPDATE: After emailing this post to Alfred McEwen of the Lunar & Planetary Laboratory in Arizona, he responded to correct an error in my image. The MRO photo was taken when Zhurong had already traveled about half the 1,300 feet listed in the Chinese article below, thus making my original circle about two times too large.

I have corrected its size. It now shows the correct maximum distance Zhurong could have driven since that MRO picture was taken on March 11th.

Original post:
——————–
According to a short report yesterday in China’s state-run press, Zhurong has traveled another 1,300 feet on Mars since it was photographed from orbit on March 11, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The report provided no information at all about the rover’s path. The map to the right shows Zhurong’s position as of March 11th, with the blue circle marking the maximum distance it could have moved since then according to this report. Based on China’s earlier vague statements, it is likely the rover has moved to the south, though even that covers a lot of possibilities.

The report did say this however:

Mars is about to enter the winter season, during which night temperatures will drop below minus 100 degrees Celsius, with a high probability of sandstorms. Martian winters last an equivalent of six Earth months.

Because Zhurong uses solar panels, it relies on the Sun for power. With coming of winter and more sandstorms, it thus faces the risk of limited solar power. As its nominal mission was only supposed to last three months, not a Martian year of 24 months that includes a winter, it will be interesting to see if it can survive that season.

The story also added that Yutu-2 has now traveled about 3,875 feet on the Moon, but added nothing else.

Space Force awards 125 small contracts to develop space junk removal and satellite repair

9:07 am

Capitalism in space: The Space Force yesterday announced the issuance of 125 small contracts, each worth $250,000, for developing new technologies for the removal of orbiting space junk as well as the robotic servicing of orbiting satellites.

SpaceWERX [a Space Force division] plans to award the 125 contracts over the next 30 days and each team will have about 150 days to deliver a product or study. Later this year they will have an opportunity to compete for second-phase awards of up to $1.5 million to continue development and prototyping.

The long-term goal is to select one or more teams two years from now to conduct an in-space demonstration of OSAM technologies, short for on-orbit servicing, assembly and manufacturing. This includes a broad range of technologies to repair and refuel existing satellites, remove and recycle orbital debris, and manufacture products in space.

Many of these development contracts likely went to already established companies like Northrop Grumman, Orbit Fab, Momentus, Launcher, and Spaceflight, which are all developing technologies for in-orbit transportation and servicing. These small contracts were also likely given to new startup companies that have not yet launched.

Berger: The media should ignore Rogozin

8:56 am

Eric Berger today beat me to the punch with a very cogent op-ed outlining how the press is consistently being fooled by the head of Roscosmos, Dmitry Rogozin, by reporting what he says without really understanding any of the larger context.

It happened again this weekend. Both Bloomberg and Axios reported that Russia is quitting the International Space Station due to sanctions imposed by the United States on Russia. Each of these stories garnered considerable attention. And each of these stories was also wrong.

…Specifically, this is what Rogozin said on state television this weekend: “The decision has been taken already, we’re not obliged to talk about it publicly. I can say this only—in accordance with our obligations, we’ll inform our partners about the end of our work on the ISS with a year’s notice.”

This may sound ominous, but that is the wrong interpretation of Rogozin’s words. There is actually some positive news in there, with Rogozin saying Russia will give NASA and its other partners a full year’s notice before departing. This is more than enough time for NASA and its commercial partners, Northrop Grumman, SpaceX, and Boeing, to work together to salvage the larger Western segment of the space station.

Rogozin’s most recent comments are even more positive than his comments in early March, when he threatened to break off the ISS partnership by the end of the month.

The ignorance of both the Bloomberg and Axios reports were amplified in that they were reporting nothing new, as Rogozin had essentially revealed this decision three weeks earlier.

The bottom line is that Russia is facing the death of its space program. It doesn’t have the cash to finance its own space station, and it has no one else to fly with. China says it will be glad to work with Russia on its Tiangong station, but it isn’t going to put out one dime to help pay for Russian efforts. Nor will the future American private stations.

Thus, most of what Rogozin says is bluster, not to be taken too seriously. Russia is going to stay with ISS for at least the next two years, and if it eventually decides to continue the partnership through ’30 it will be no surprise.

Rocket Lab successfully catches first stage with helicopter

4:13 pm

Electron first stage on parachute just before capture

Capitalism in space: In successfully placing 34 smallsat into orbit today using its Electron rocket, Rocket Lab also successfully caught the first stage with helicopter as it descending by parachute.

The screen capture to the right from the live feed shows that first stage on parachute just before the helicopter hook captures it. That helicopter is now returning to land with that stage, which it will then gently deposit for study and refurbishment. Though it is likely this first recovered first stage will not get reused, that possibility remains, and regardless this success points to the future reuse of all Electron first stages.

UPDATE: Because of “different load characteristics” than seen during previous tests, the helicopter pilot released the stage for safety reasons, while still over the ocean. The company was then able to recover it, but though they can now study it no reuse will be possible.

The leaders in the 2022 launch race:

17 SpaceX
13 China

Pushback: Sports anchor sues ESPN for punishing her for expressing opinions on her own time

2:23 pm

ESPN: Proud censor of free speech
ESPN: Proud censor of free speech

They’re coming for you next: Sports anchor Sage Steele last week filed a lawsuit against her employer ESPN for punishing her in 2021 when she expressed strong public reservations — on her own time — about the company’s mandates requiring employees to get COVID shots and boosters or lose their jobs.

In comments last September on a podcast hosted by former National Football League quarterback Jay Cutler, Ms. Steele touched on political and social topics, questioning Covid-19 vaccine mandates and former President Barack Obama’s decision to identify as Black instead of biracial.

After Ms. Steele’s remarks drew criticism in the press and on social media, ESPN forced her to issue an apology and temporarily benched her, according to the suit, which was served in Connecticut, where the network is based. ESPN also retaliated by taking away prime assignments and failing to stop bullying and harassment by Ms. Steele’s colleagues, the suit alleges.

The complaint says ESPN’s handling of Ms. Steele’s situation was an example of selective enforcement of a network policy that bars news personnel from taking positions on political or social issues. ESPN has “violated Connecticut law and Steele’s rights to free speech based upon a faulty understanding of her comments and a nonexistent, unenforced workplace policy that serves as nothing more than pretext,” according to the suit, which seeks unspecified damages.

You can read the lawsuit here [pdf]. It cites numerous examples of other ESPN anchors making public very partisan political statements, on air and while working for ESPN, with no consequences. It also describes in detail the network’s ugly treatment of her– including taking her off prime assignments and forcing her to issue an apology she did not write — all based on this kind of non-research:

Watch Rocket Lab launch and attempt to capture first stage with helicopter

1:20 pm

I have embedded below the live stream of Rocket Lab’s launch today from New Zealand, scheduled for a 3:41 pm (Pacific) liftoff. The rocket carries 34 satellites for deployment.

More exciting however will be the attempt to recover the first stage. On this launch the Electron rocket’s first stage will control its descent using both thrusters and parachutes so that a helicopter can make the first attempt to snatch it out of the air before it hits the ocean.

If successful, Rocket Lab will then hopefully be able to reuse the first stage on a later launch.

Navigating a rover on Mars

9:32 am

16 photos taken by Perseverance's right navigation camera on May 2, 2022

Overview map
Click for interactive map.

Cool image time! The photo to the right is actually a screen capture of 16 consecutive photos taken on May 2, 2022 by the right navigation camera on the Mars rover Perseverance.

The overview map below gives the context. The red dot marks Perseverance’s position when the photos were taken. The green dot marks Ingenuity’s position. The small white dot marks the spot where the rover’s parachute landed. The yellow lines indicate I think the area covered by the sixteen navigation images.

There is a reason for showing this panorama in this somewhat crude form. The engineers who run Perseverance have programmed its navigation cameras to send back its pictures so that they immediately line up in this coherent pattern. There is no need to rearrange them upon arrival. The engineers thus can instantly see how each picture relates to the others, and thus get an immediate sense of the nearby terrain in which they must plot the rover’s next move.

Perseverance is now in its second science campaign, focused on studying the base of the delta. As the science team studies the delta’s cliff face, they are also studying the best route to continue uphill. To do both, they have begun slowly moving along that face, going from west to east.

The rough panorama above thus shows them the ground ahead as they continue that traverse. I expect the rover’s next move will be to the northeast, once again moving along the base of the nearest cliff. The panorama shows that while the ground in this area has a few ridges, none are so high as to cause Perseverance any problems.

Update on Dream Chaser

10:57 am

Link here.

Overall progress has been incredibly slow, considering the NASA contract to build this was awarded in 2016. Sierra Space is only building one spacecraft, designed to be reusable. For six years to have passed and the spacecraft, dubbed Tenacity, is still a year away from flight, seems excessive, especially because the spaceplane is small. It took SpaceX only four years to go from concept to successfully landing first stages. Starship began test flights only three years after the project began.

Still, the spaceplane is moving forward. Hopefully by February ’23 it will finally fly, giving the U.S. another method besides Dragon for getting cargo to and from space. That it might do so before Boeing’s Starliner is somewhat ironic, and puts more pressure on that company to get that capsule operational.

China and Russia each successfully complete launches

10:25 pm

Both China and Russia successfully completed launches in the past few hours.

First, shortly before midnight today (local time) Russia used its smaller version of its new Angara rocket to place a military satellite into orbit, launching this version of the rocket for the second time.

Next, using its solid rocket Long March 11, China on April 30th (local time) successfully launched five smallsats from an ocean platform in the East China Sea. This was the third launch from sea by the Long March 11.

The leaders in the 2022 launch race:

17 SpaceX
13 China
6 Russia
2 ULA
2 Rocket Lab

The U.S. still leads China 24 to 13 in the national rankings. The U.S. also still leads all other nations and companies combined, 24 to 22.

Brain terrain in Mars’ glacier country

Brain terrain in glacier country
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on February 10, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

It shows what planetary scientists have dubbed “brain terrain”, a truly unique Martian geological feature that is not found on Earth and also remains as yet unexplained. Specifically, the brain terrain is the speckled areas between the larger flow features, all of which are probably ice or glacier related.

What especially drew me to this MRO image however was the particular flow feature in the center left that looks like either a giant squid or something out of Lovecraft horror short story. Talk about a cool image!

The downward grade here is likely to the north, as this spot is inside a north-south canyon, cutting into the southern cratered highlands. The general north-south trend of the depression here reinforce this supposition.

The overview image below provides context.
