Scientists want your help cataloging the clouds on Mars

9:49 am

In order to fully identify all the clouds seen in the sixteen years of data collected by the cloud instrument on Mars Reconnaissance Orbiter (MRO), scientists have now organized a citizen-scientist project to catalogue those clouds.

The project revolves around a 16-year record of data from the agency’s Mars Reconnaissance Orbiter (MRO), which has been studying the Red Planet since 2006. The spacecraft’s Mars Climate Sounder instrument studies the atmosphere in infrared light, which is invisible to the human eye. In measurements taken by the instrument as MRO orbits Mars, clouds appear as arches. The team needs help sifting through that data on Zooniverse, marking the arches so that the scientists can more efficiently study where in the atmosphere they occur.

SpaceX preps for final engine tests before first orbital Starship/Superheavy flight

9:42 am

Capitalism in space: Having moved its 7th prototype Superheavy booster to the launch pad in Boca Chica even as its installs the six Raptor engines on the 24th prototype of Starship, SpaceX is now about to begin the final engines tests prior to the first orbital Starship/Superheavy flight.

For the first time the chopstick arms on the launch tower were used to lift and place the Superheavy booster onto the pad. It is expected that static fire tests of its 33 Raptor engines could begin within the next few weeks.

The orbital Starship meanwhile is still in the assembly building, where engineers are installing its own six Raptor engines.

Though SpaceX has not made public the exact schedule of tests leading to launch, it is expected that the company will do a short static fire test program with Superheavy alone, and then do a follow-up short series of tests once the Starship prototype is stacked on top. Based on past history, if the tests show no problems SpaceX will quickly move to launch. Though there have been indications that it is targeting July, it would not be surprising if that date slips to August.

The race between Starship and SLS for which will get into orbit first appears to be tightening.

An evening pause: Unlike yesterday’s song, this song should be the anthem for today’s generation, especially the men. The chorus:

How to know when it’s love
How to stay when it’s tough
How to know you’re messing up a good thing
And how to fix it fore it’s too late
And yea I know a boy
Who gave up and got it wrong
If you really love a woman you don’t let her go
Yeah I know few things a man oughta know

Science! Psychology researchers discover that kids make friends with those who sit next to them in school

3:34 pm

Your tax dollars at work! Psychology researchers at Florida Atlantic University have found to their shock that the friendships school children form are strongly influenced by their seat assignments in class.

Results of the study, published in the journal Frontiers in Psychology, revealed that friendships reflect classroom seat assignments. Students sitting next to or nearby one another were more likely to be friends with one another than students seated elsewhere in the classroom. Moreover, longitudinal analyses showed that classroom seating proximity was associated with the formation of new friendships. After seat assignments changed, students were more likely to become friends with newly near-seated classmates than with those who remained or became seated farther away.

You can read the actual paper here. The research itself was apparently funded by a grant from National Institute of Child Health and Human Development (NICHD), apparently an agency within NIH, that stellar agency that pushed masks, lockdowns, and social distancing during the past two years based on zero data and contrary to research results going back decades.

It seems to me that this result would be obvious to any first grade teacher who is focused on teaching kids. It is also obvious to anyone who ever went to school and made friends there. To spend money on such research is utterly idiotic. Worse, it diverts funds from research that is considerably more important.

But no matter. What is really important is to get funding, no matter how trivial or useless the research. And our corrupt and bankrupt federal bureaucracy is most willing to oblige.

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.

Pushback: Students win major settlement with college for denying them their free speech rights

11:48 am

Chike Uzuegbunam: winner against college censorship
Chike Uzuegbunam: A winner against college censorship

Bring a gun to a knife fight: Because the Supreme Court had ruled 8-1 in March 2021 that Georgia Gwinnett College and its officials could be held liable for damages for illegally denying several religious students their first amendment rights, the university last week finally settled the five-year-long case in favor of those students, paying nominal damages and attorneys’ fees totaling more than $800,000.

The case began when the university in 2016 twice prevented two students, Chike Uzuegbunam and Joseph Bradford, from talking to other students about their religious faith on campus. The first time the university claimed that, according to its speech zone policies, the students could only do so after getting permission from the school and then limiting their speech to a tiny free speech zone on campus. When Uzuegbunam followed this policy, school officials then banned him from speaking entirely because someone had complained. From the Supreme Court’s March 2021 ruling [pdf]:

Scientists claim rocket launches are going to damage ozone layer

9:25 am

Junk science: This week NOAA government scientists published a paper claiming that the upcoming increase in rocket launches worldwide is a threat to the ozone layer and will also — my heart be still — promote climate change!

The study found that a tenfold increase in the amount of soot injected into the stratosphere every year would after 50 years lead to an annual temperature increase in that layer of 1 to 4 degrees Fahrenheit (0.5 to 2 degrees Celsius). The stratosphere is the layer of the atmosphere just above the lowest troposphere. The study found that the projected warming would slow down subtropical jet streams, bands of strong wind circling the planet at the lower edge of the stratosphere that influence the African and Indian summer monsoons.

Warmer temperatures in the stratosphere would also degrade the protective ozone layer, which blocks harmful ultraviolet radiation from the sun from reaching the planet’s surface.

The paper’s abstract also said this:

We show that the rocket black carbon increases stratospheric temperatures and changes the global circulation, both of which cause a reduction in the total ozone column, mainly in the northern high latitudes. Comparing the amplitude of the atmospheric response using different emission rates provides insight into stratospheric adjustment and feedback mechanisms. Our results show that the stratosphere is sensitive to relatively modest black carbon injections.

This is garbage science, and I wouldn’t bother posting a link to it if other news sources weren’t promoting it. These predictions — based on a very simple computer model — are nothing more than guesses, and are apparently designed to both attack the growing space industry as well as garner funding for more such junk science, as illustrated by this quote from the NOAA press release:

“We need to learn more about the potential impact of hydrocarbon-burning engines on the stratosphere and on the climate at the surface of the Earth,” said lead author Christopher Maloney, a CIRES research scientist working in NOAA’s Chemical Sciences Laboratory. “With further research, we should be able to better understand the relative impacts of different rocket types on climate and ozone.”

For almost a half century climate scientists — many working for government agencies like NASA and NOAA — have been publishing junk papers like this, predicting climate doom in only a few decades unless we do as they say, while funneling boatloads of cash into their pockets. Almost none of those predictions have turned out to be correct.

This report is equally suspect, especially because it touts the false statistic that “launch rates have tripled in recent decades.” The number of launches has not tripled from its long-term average since Sputnik. The only way you can get manufacture that fake statistic is if you compare last year’s total (134) with the launch numbers from the early 1960s, before the space race had even begun. And while the launch numbers are likely to rise dramatically in the coming years, the numbers will still be infinitesimal compared to other industries. Going from 50-100 launches to 200-500 launches is hardly the end of the world.

It really is far past time for the press and the general public to stop listening to these fake papers.

Virgin Orbit signs deal to launch from Brazil

9:02 am

Capitalism in space: Virgin Orbit yesterday announced that it has signed an agreement with the Brazil Space Agency (AEB) to establish facilities and conduct launches from that nation’s long unused Alcântara spaceport.

The license is granted to Virgin Orbit Brasil Ltda. (VOBRA), a newly formed and wholly owned Brazilian subsidiary dedicated to bringing the LauncherOne air-launch rocket system to the Alcântara Launch Center (Centro de Lançamento de Alcântara, CLA).

The formation of the VOBRA entity for dedicated Brazilian space activities is designed to bring an important new capability to the country and economic value to the region. Virgin Orbit’s LauncherOne system, which uses a customized 747 aircraft, Cosmic Girl, as its flying and fully reusable launch pad, will conduct launches from the existing airbase at the Brazilian site, flying hundreds of miles before releasing the rocket directly above the equator — a global sweet spot — or at other optimal locations identified for each individual mission.

Being able to launch smallsats from the equator gives Virgin Orbit the ability to place those satellites in any orbit around the Earth for far less fuel, an advantage not available to spaceports at higher latitudes.

China and Rocket Lab complete successful launches

8:51 am

Two launches this morning herald the upcoming busy launch schedule for the last few days of June.

First China launched from its Jiuquan interior spaceport an Earth observation satellite using its Long March 4C rocket. As is usual with China, the first stage crashed on land, though no details have been provided.

Next, Rocket Lab used its Electron rocket to send NASA’s CAPSTONE cubesat lunar probe on its way to the Moon. More information here.

CAPSTONE is currently in low-Earth orbit, and it will take the spacecraft about four months to reach its targeted lunar orbit.

…CAPSTONE is attached to Rocket Lab’s Lunar Photon, an interplanetary third stage that will send CAPSTONE on its way to deep space. Shortly after launch, Lunar Photon separated from Electron’s second stage. Over the next six days, Photon’s engine will periodically ignite to accelerate it beyond low-Earth orbit, where Photon will release the CubeSat on a ballistic lunar transfer trajectory to the Moon. CAPSTONE will then use its own propulsion and the Sun’s gravity to navigate the rest of the way to the Moon. The gravity-driven track will dramatically reduce the amount of fuel the CubeSat needs to get to the Moon.

Once at the Moon, the spacecraft will enter a polar orbit varying from 1000 to 43,500 miles from the surface, with its prime mission to test operations in that lunar orbit.

Not only did NASA hire a private company, Rocket Lab, to launch it, the agency also hired a private company, Terran Orbital, to build it.

The leaders in the 2022 launch race:

26 SpaceX
21 China
8 Russia
4 Rocket Lab

American private enterprise still leads China 36 to 21 in the national rankings, and the entire world combined 36 to 34.

For the rest of June, the American companies SpaceX, Virgin Orbit, and ULA all have planned launches, as well as India. If all succeed, that would put the total launches in the first half of ’22 at 74, a pace that would almost reach 150 launches by the end of the year, smashing the annual record set last year. The U.S.’s pace in turn is likely to exceed the number of launches it completed in all of ’22 in July, with the possibility it could complete 75-80 launches by the end of the year, exceeding the U.S. annual record of 70 set in 1966.

Did pieces of a Chinese upper stage land in middle of Mediterranean last week?

11:44 pm

According to a tweet from a Twitter account that specializes in reporting on the Chinese space program, at least one piece of the upper stage from the Long March 2F rocket that launched the present Tiangon space station crew on the Shenzhou-14 crashed into the middle of Mediterranean Sea when the stage’s orbit decayed.

Most parts burned during the reentry while small debris splashed in Mediterranean Sea around E5.2° N39.1°

According to both this Twitter site as well as the Aerospace Corporation’s re-entry site, the event occurred on June 20, 2022. The latter site however says the stage burned up over the Atlantic, though it also indicated a one hour margin of error both before or after that time. If the stage thus stayed up just a bit longer, its orbit would have brought it down exactly where the former site states.

If this is so, it indicates that the Chinese either could not or made no effort to control the de-orbit, something that should be standard for any upper stage that has mass that could hit the ground.

It breaks my heart to know that these lies have robbed a whole generation of hope and faith in the greatness that is possible in all humans. And without hope or faith in doing the impossible, not even the possible will be easy.

A thick and syrupy flow on Mars

A thick and syrupy flow on Mars
Click for full image.

Overview map

Cool image time! The photo above, rotated, cropped, and reduced to post here, was taken on March 5, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as a “viscous flow feature,” which is another way of saying the flow was thick and syrupy.

Nor is such a flow unusual in this area of Mars. It is located in a region of chaos terrain dubbed Protonilus Mensae, which is also the central mensae region in the 2,000-mile-long strip in the northern mid-latitudes of Mars I label glacier country. The overview map above of Protonilus Mensae — covering about 500 miles in width — shows how common such flows are in this place. The black rectangles mark the locations of other cool images I have featured, as follows:

The red rectangle indicates the location of today’s cool image.

The glacial aspect of everything in this region is even more emphasized by the wider view provided by MRO’s context camera below.

Pushback: Supreme Court rules in favor of HS football coach fired for praying

11:27 am

Joe Kennedy: An American once again free to pray
Joe Kennedy: An American once again free to pray,
when and where he wishes.

Bring a gun to a knife fight: In a 6-3 decision, the Supreme Court today ruled in favor of high school coach Joe Kennedy, who was fired by the Bremerton School District in Washington because he choose to kneel and pray quietly on the football field at the end of each game.

Joe Kennedy was a junior varsity head coach and varsity assistant coach with the Bremerton School District in Washington from 2008 to 2015. He began the practice of reciting a post-game prayer by himself, but eventually students started joining him. According to court documents, this evolved into motivational speeches that included religious themes. After an opposing coach brought it to the principal’s attention, the school district told Kennedy to stop. He did, temporarily, then notified the school that he would resume the practice.

The situation garnered media attention, and when Kennedy announced that he would go back to praying on the field, it raised security concerns. When he did pray after the game, a number of people stormed the field in support.

The school district then offered to let Kennedy pray in other locations before and after games, or for him to pray on the 50-yard line after everyone else had left the premises, but he refused, insisting that he would continue his regular practice. After continuing the prayers at two more games, the school district placed Kennedy on leave.

He eventually lost the job when the school district refused to renew his contract.

You can read the Supreme Court’s ruling here [pdf].

Initially Kennedy was holding locker room prayer sessions and postgame religious talks, actions by a public school teacher that are certainly inappropriate. However, when the district demanded these stop he did so.

Subsequently he began praying on the field, alone and silent, after games. This action did attract some students to join him, but since he did not require participation he was violating no one’s rights, nor was he acting as a government agent at that time.

New research suggests flowing water existed intermittently on Mars from 2.5 to 3.6 billion years ago.

9:26 am

Based on a study of alluvial fans on Mars, river sediment thought to have been placed at the foot of mountains, scientists have concluded that liquid water could have been flowing from as 2.5 to 3.6 billion years ago.

“We’ve known for decades that Mars had rivers and lakes around 3.5 billion years ago, but in the past few years there has been a growing body of evidence that substantial amounts of liquid water continued to erode the Martian surface for hundreds of millions of years,” said Morgan, lead author on “The global distribution and morphologic characteristics of fan-shaped sedimentary landforms on Mars” that appears in Icarus. “Water-formed landforms, such as river deltas and alluvial fans, are the most unambiguous markers of past climate. So we conducted a global survey for these features and explored patterns in their distribution and morphologic properties.”

Morgan and co-authors including PSI Senior Scientist Alan Howard found that alluvial fans are found at lower elevations than the more ancient valley networks, suggesting that stable liquid water became restricted to lower, warmer regions as Mars cooled and dried.

…What is particularly interesting about the Martian fans is that many formed much later than the valley networks, which have long been considered the strongest evidence for surface water on early Mars. Valley networks largely date to around 3.6 billion years ago, but alluvial fans date to 2.5 to 3 billion years ago.

This research merely increases the fundamental geological mystery of Mars. While the surface evidence strongly tells us that liquid water once flowed on the surface, no climate model exists that satisfactorily makes that possible. The atmosphere appears to have always been too cold and thin for liquid water.

NASA completes suborbital launch from commercial spaceport in Australia

8:59 am

Early this morning NASA successfully completed its first rocket launch from Australia since 1995, launching a suborbital payload from a new commercial spaceport on the northern coast of Australia.

The rocket is Nasa’s first of three to blast off from the newly constructed Arnhem Space Centre on the edge of the Northern Territory. Scientists hope it will help them study the impact of a star’s light on the habitability of nearby planets.

Onlookers who travelled to the remote site glimpsed the rocket for only about 10 seconds before it shot out of view.

After a short fifteen minute flight the sounding rocket and payload were recovered. The next suborbital launch is scheduled for July 4th.

Iran claims it has completed a second suborbital test of new rocket

8:48 am

According to Iran’s state-run press, it yesterday successfully completed the second suborbital test of its new Zuljanah rocket.

The announcement said nothing about where or when the launch took place. According to this Iranian report, the rocket “has two solid propulsion phases and a single liquid propulsion phase.”

The rocket had completed a suborbital test in January 2021. In March 2022 satellite imagery suggested a second test had exploded on the launchpad sometime in late February.

Since the video of the launch provides no specific information about where or when, it is quite possible it is simply footage from the January 2021 launch. It will require orbital imagery to confirm this claim.

German smallsat rocket startup signs orbital tug startup as launch customer

9:54 am

Capitalism in space: Isar, one of three German smallsat rocket companies hoping to launch their own rockets, has won a launch contract from D-Orbit, one of three companies building orbital space tugs designed to provide in-orbit transportation to cubesats.

Isar Aerospace announced today that it has entered into a firm launch services agreement with space infrastructure pioneer D-Orbit. The company’s launch vehicle Spectrum, which is developed for small and medium satellites and satellite constellations, will launch D-Orbit’s ION Satellite Carrier as a primary customer to a Sun-synchronous orbit from its launch site in Andøya, Norway with a launch term starting in 2023.

This is Isar’s third launch contract. The company has also raised almost $200 million in investment capital in the past year and a half.

Cygnus freighter fires engine, adjusts ISS orbit for first time

9:47 am

For the first time the engines on a Cygnus capsule were used successfully yesterday to adjust the orbit of the International Space Station (ISS).

On Saturday, June 25, Northrop Grumman’s Cygnus completed its first limited reboost of the International Space Station. Cygnus’ gimbaled delta velocity engine was used to adjust the space station’s orbit through a reboost of the altitude of the space station. The maneuver lasted 5 minutes, 1 second and raised the station’s altitude 1/10 of a mile at apogee and 5/10 of a mile at perigee. This Cygnus mission is the first to feature this enhanced capability as a standard service for NASA, following a test of the maneuver which was performed in 2018 during Cygnus’s ninth resupply mission.

NASA’s goal is to have this capability without relying on Russia’s Progress capsules, which up until now have been used to adjust the station’s orbit. It appears from yesterday’s test this this goal has now been met.

Blue Origin abandons plans to land New Glenn first stages on purchased cargo ship

9:31 am

Capitalism in space: This week it was revealed that Blue Origin has abandoned its plan to use a purchased and refurbished cargo ship as an ocean landing platform for the first stages of its New Glenn rocket.

The company had bought the ship in 2018, when it thought New Glenn would be flying by 2020, and planned to reconfigure it by covering it with a giant landing pad. It appears the company abandoned that plan because of cost. What it plans to do instead to provide New Glenn first stages a place to land remains unclear.

Some historical details that provide some context and might explain the change in plans. In 2016 Blue Origin was launching test flights of its New Shepard suborbital craft on almost a monthly basis. It appears to have an aggressive attitude towards development, with New Glenn aiming for a 2020 launch.

In 2017 Jeff Bezos hired Bob Smith to take over as Blue Origin’s CEO. At that point development slowed to a crawl. For the next four years New Shepard test flights dropped to about one per year. Also at that time development of the BE-4 rocket engine needed for both New Glenn and ULA’s Vulcan rocket also slowed to a crawl, apparently because the company’s management would not commit funds to buy extra engines for testing.

In 2018 Blue Origin signed a deal with the Air Force, thus delaying New Glenn’s first launch by a year. The deal appeared to stem from a desire of Blue Origin management to get government contracts and money first rather than committing any company money to development, the approach used by older big space companies for decades. While it reduces risk, this approach also makes the government a partner in development, which has historically slowed all development while significantly raising costs.

That same year it bought this ship as the rocket’s landing pad, though relatively little work is done on it for years.

In 2021 Jeff Bezos stepped down as Amazon CEO to focus more time on Blue Origin. Suddenly, New Shepard ups its launch rate, and finally starts flying passengers. At the same time, the testing of the BE-4 engine appears to accelerate.

Now Blue Origin is abandoning this ship that was purchased after Bob Smith took over.

Does one get the feeling that Bezos might have finally realized that the management under Smith was not very effective? Smith is still Blue Origin’s CEO, but one wonders how long this will last.

Psyche will not launch as scheduled

9:06 am

NASA officials yesterday confirmed that because of software issues its asteroid mission Psyche will not launch as scheduled this year.

Due to the late delivery of the spacecraft’s flight software and testing equipment, NASA does not have sufficient time to complete the testing needed ahead of its remaining launch period this year, which ends on Oct. 11. The mission team needs more time to ensure that the software will function properly in flight.

…As the mission team at NASA’s Jet Propulsion Laboratory in Southern California began testing the system, a compatibility issue was discovered with the software’s testbed simulators. In May, NASA shifted the mission’s targeted launch date from Aug. 1 to no earlier than Sept. 20 to accommodate the work needed. The issue with the testbeds has been identified and corrected; however, there is not enough time to complete a full checkout of the software for a launch this year.

NASA management will conduct a review to understand what caused the problem.

As for when Psyche can next launch and reach the asteroid Psyche, the next launch windows in ’23 and ’24 will not arrive at the asteroid until ’29 or ’30 respectively, a flight time that is about two years longer than what the ’22 launch would have been.

Today’s blacklisted Americans: Lawyers who won NY gun rights case in Supreme Court blackballed by their law firm

1:06 pm

A witch hunt against conservative lawyers
The witch hunt against conservative lawyers accelerates.

Blacklists are back and the Democrats have got ’em: The two lawyers who recently won a major gun rights victory in the Supreme Court this week, invalidating the “may-issue” gun control laws in leftist states that prevented anyone from obtaining a gun license, have been blackballed by their law firm, Kirkland & Ellis, and forced to resign.

Former Solicitor General Paul Clement and Erin Murphy, a regular Supreme Court litigator, resigned from Kirkland & Ellis and announced they were opening their own shop in Washington, D.C. Clement has been a high-profile litigator of conservative causes since he left the administration of President George W. Bush. In 2011, he argued the Defense of Marriage Act on behalf of Republican lawmakers before the Supreme Court.

That case also caused Clement to resign from the firm King & Spalding following pressure from clients to drop the gay marriage case.

Perseverance’s first climb

Perseverance's first climb
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken by the high resolution camera on the Mars rover Perseverance on June 16, 2022, shortly after it began its first climb up from the generally flat floor of Jezero crater and onto the delta that once in the far past flowed through a gap into that crater.

I have rotated the image about 8.5 degrees to make horizontal the crater floor and the distant rim of the crater (barely visible through the atmosphere’s thick winter dust). This shows that the rover was then climbing what appears to be a relative low angle grade, hardly as challenging as the serious grades that Curiosity has been dealing with now for the past two years in the foothills of Mount Sharp. Nonetheless, Perseverance has begun climbing.

To see where the rover is see the overview map from the start of this week. Unfortunately, I have been unable to determine the direction of this photo. It could be looking west, south, or east, based on features inside Jezero Crater. I therefore cannot tell you the distance to the rim, which depending on the direction, could be from five to twenty-five miles away.

NASA now targeting late August launch of SLS

11:35 am

NASA officials today confirmed that they are satisfied with the results from this week’s incomplete dress rehearsal countdown of the SLS rocket, and are targeting a late August launch of SLS.

NASA officials have reviewed the data collected during the test run and decided that a leaky hydrogen valve was not significant enough to force a delay in the launch of Artemis I, an uncrewed mission planning to orbit the moon and return to Earth. It’s the first step toward putting humans back on the moon for the first time since Apollo 17 in 1972.

“The team is now ready to take the next step and prepare for launch,” said NASA’s deputy associate administrator Tom Whitmeyer.

NASA officials said they will roll the massive Space Launch System rocket back to the Vehicle Assembly Building, where the valve’s faulty seal will be replaced. Rollback is slated for Friday July 1, though weather concerns could push that back.

SLS won the five-plus year race with the Webb telescope on which would have the most delays and launch last. Now the race will be between SLS and SpaceX’s Starship/Superheavy. Which will launch first this summer? In a rational world, SLS should win hands down. It has been in development since 2004, while Starship only began design work in 2017.

This is not a rational world, however, and SLS’s long gestation had little to do with designing a rocket and everything to do with politics and a corrupt Congress and an incompetent NASA. The rocket that has come out of this is thus difficult to operate and incredibly cumbersome. Its components have also not been tested thoroughly.

SpaceX meanwhile has been designing and building its heavy-lift rocket with only one goal: the rocket must be efficient to operate.

I predict Starship will reach orbit first, though if it doesn’t it most likely will be because SpaceX finds it needs to do more ground tests and revisions, not because SLS has surged ahead. And regardless, Starship will likely fly many times in the next three years, while SLS will only get off the ground once.

More important, the chances of SLS and Orion working perfectly throughout that that lunar orbit mission seem almost impossible, based on track record during the past eighteen years of both programs. Expect some issues to crop up, first during the launch countdown, forcing several scrubs, and then during the mission itself. None might be mortal, but all will raise questions whether it would be wise to put humans on this rocket and capsule on its next flight, and attempt to take them to the Moon.

NASA halts sale of Apollo 11 Moon dust, claiming ownership

10:37 am

We’re here to help you: The auction of a tiny amount of Moon dust brought back by Apollo 11 and used in a post-flight experiment using German cockroaches has been canceled because NASA claimed ownership of that dust and demanded its return.

“NASA asserts legal ownership of the materials consisting of the Apollo 11 lunar dust experiment … based upon the information and documentation provided in the description of the lot and evidence regarding NASA’s contemporaneous contracting practices,” an attorney in NASA’s Office of the General Counsel wrote RR Auction in a letter on Wednesday, a week after first reaching out to the firm. “It is clear and undeniable that the materials consisting of the experiment are owned by NASA.”

The lot under contention comprises what remains from the late Marion Brooks’ research into the physiological effects of lunar material on Blattellas germanica, or German cockroaches. The insects had been fed moon dust by NASA scientists in the immediate aftermath of the 1969 Apollo 11 lunar landing mission. After no ill-effects were seen while astronauts Neil Armstrong, Buzz Aldrin and Michael Collins were held in quarantine, the (now dead) cockroaches were handed off to Brooks, an entomologist from the University of St. Paul, for more thorough study.

Included in the auction was a small vial of moon dust that Brooks’ had carefully extracted from the cockroaches’ corpses, as well as three of the remaining (dead) cockroaches and two boxes of tissue slides for microscopic study.

It appears the dust had been in the Brooks family possession for more than forty years, then sold by them at auction in 2010 for $10,000. Under standard adverse possession law, you lose ownership if you don’t claim that right after twenty years. It would thus seem that NASA’s claim is bogus.

But then, NASA as a government agency doesn’t believe the standard laws apply to it. It continues to demand that all Apollo lunar material belongs to it and be returned, no matter what the circumstances it was originally handed out by the agency and no matter how long ago.

LRO scientists locate impact on Moon from rocket stage believed to be Chinese

10:26 am

Impact, before and after

The science team for Lunar Reconnaissance Orbiter (LRO) today released images identifying the location on the Moon where a mystery rocket stage crashed in March 2022.

The image to the right shows the before and after LRO images, with the impact at the center of the second photo, showing as two superimposed craters. Since the sunlight in the second image come from the opposition direction as the first, the shadows in all previously existing craters are reversed.

Surprisingly the crater is actually two craters, an eastern crater [59 feet diameter] superimposed on a western crater [52 feet diameter]. The double crater was unexpected and may indicate that the rocket body had large masses at each end. Typically a spent rocket has mass concentrated at the motor end; the rest of the rocket stage mainly consists of an empty fuel tank. Since the origin of the rocket body remains uncertain, the double nature of the crater may help to indicate its identity.

No other rocket body impacts on the Moon created double craters. The four Apollo SIV-B craters were somewhat irregular in outline (Apollos 13, 14, 15, 17) and were substantially larger [>115 feet in diameter] than each of the double craters. The maximum width [95 feet] of the double crater of the mystery rocket body was near that of the S-IVBs.

Though the evidence strongly points to this stage being from China, that fact is not certain, and China denies that conclusion.

Regardless, the unexpected double nature of the impact only increases the mystery, as it suggests that rocket stage had a mass distribution different than past stages.

NASA blocks Starship/Superheavy launches at SpaceX’s new Florida launchpad

9:37 am

Capitalism in space: NASA officials revealed yesterday that it will not allow any Starship/Superheavy launches at SpaceX’s new Florida launchpad, at least for the moment, because of the threat a launchpad failure might have on the launchpad SpaceX uses to launch manned Falcon 9 missions to ISS.

The NASA statement said the agency “is responsible for ensuring SpaceX remains compliant with the requirements of the property agreement for the use of Launch Complex 39A.”

“These requirements include those related to construction, safety and environmental conditions,” the statement said. “At this time, NASA has only provided approval to build. Additional review for hazards, operational impacts and supportability will be required prior to a launch.”

The new Starship launchpad is 1,000 feet away from pad 39A, which is SpaceX’s manned Dragon launchpad. NASA management thinks this is too close. However, the managers have also not ruled out future launches, only that they wish to do a thorough review of the issue with SpaceX.

Because NASA and the federal government is also relying on Starship to land its astronauts on the Moon, it can’t block Starship flights outright. It could be however that this issue might shift Starship operations back to Boca Chica, after federal government opposition there forced SpaceX to shift more operations to Florida.

In other words, the government wants its cake and eat it to. Some factions within the Biden administration and the Washington bureaucracy want to block Starship, others want it to fly. The result is a tug-of war, with SpaceX in the middle.

OneWeb to resume satellite launches this year, complete constellation by mid-2023

9:24 am

Capitalism in space: According to one OneWeb official at a conference yesterday, the company now expects to resume launching its satellites on SpaceX and Indian rockets by the fourth quarter of this year and will complete its constellation by the second quarter of next year.

Launches were suspended when Russia refused to do a launch — and confiscated the 36 satellites — after Europe imposed sanctions in response to the Russian invasion of the Ukraine.

Speaking at the Fourth Summit for Space Sustainability by the Secure World Foundation and the U.K. Space Agency, Maurizio Vanotti, vice president of space infrastructure development and partnerships at OneWeb, said new launch agreements with SpaceX and NewSpace India Ltd. (NSIL) would allow the company to launch the remaining satellites of its first-generation system by the second quarter of 2023.

“Our plan is to be back on the launch pad in quarter four, after the summer, and to complete deployment of the constellation by quarter two next year,” he said. It will take several months after that final launch for the satellites to move to their operational orbits, he added. “We’re going to be in service with global coverage, 24/7, by the end of next year,” he said.

At present OneWeb has not revealed the breakdown of launches from the two companies.

Blue Origin’s BE-4 engine set for “commissioning” tests

1:29 pm

Capitalism in space: According to a tweet from Blue Origin on June 21, 2022, engineers have finally installed a flight-worthy engine on the test stand in Huntsville for static fire “commissioning” tests.

This is an engine that was supposed to be delivered to ULA for its new Vulcan rocket more than two years ago. With final engine tests only beginning now, it likely means the engine will not be delivered for at least several more months.

ULA will then have to install it in the rocket, and do its own fueling and static fire tests. All this suggests that a Vulcan launch before the end of this year is almost impossible.

When Blue Origin’s own New Glenn rocket will fly using the BE-4 is utterly unknown. ULA at least has built a full-scale test version of Vulcan and done launch countdown rehearsals in order to iron out issues with its launchpad and ground systems. Blue Origin has done none of this.
