Have astronomers found an exoplanet with raining metal and gems?

9:33 am

The uncertainty of science: Using data from the Hubble Space Telescope, astronomers think they have detected on a hot Jupiter exoplanet 880 light years away the formation of clouds and rain made up metals and gems.

The exoplanet is tidally locked so that one side always faces its star, which also means the temperature difference between the two hemispheres is gigantic, 5,400 degrees Fahrenheit on the dayside and about 2,600 degrees on the nightside.

Previous Hubble data showed signs of metals including iron, magnesium, chromium and vanadium existing as gasses on the planet’s dayside. But in this study, the researchers have found that on the planet’s nightside, it gets cold enough for these metals to condense into clouds.

And, just as the strong winds pull water vapor and atoms around the planet to break apart and recombine, metal clouds will blow to the planet’s dayside and evaporate, condense back on the nightside and so on.

But metal clouds aren’t the only strange phenomenon these researchers spotted on this hot Jupiter. They also found evidence of possible rain in the form of liquid gems.

While tantalizing and alien, these results have many uncertainties. What the data suggests might not be the reality. To find out more, the astronomers hope to use the James Webb Space Telescope to do more infrared observations, once it becomes operational.

China denies the rocket stage about to hit the Moon comes from its rocket

9:23 am

A Chinese official yesterday claimed that the abandoned rocket stage that will hit the Moon on or about March 4th does not come from its 2014 Long March 3C rocket that tested technology for the later launched Chang’e-5 lunar sample return mission, as suggested by amateur astronomers and an engineer at JPL.

“According to China’s monitoring, the upper stage of the rocket related to the Chang’e-5 mission entered into Earth’s atmosphere and completely burned up,” Foreign Ministry spokesperson Wang Wenbin said Feb. 21.

Space tracking data from the Space Force’s 18th Space Control Squadron suggests that 2014-065B—the international designator for the rocket stage in question—reentered the atmosphere in October 2015, a year after launch, apparently backing China’s claim.

We are thus left with a mystery. If that abandoned upper stage did not come from either a SpaceX or Chinese launch, what launch did it come from? Or is it a rocket stage at all? Could it be a previously unidentified asteroid?

There is also the possibility that it is a piece from that Chinese launch, considering how the orbital data matches so well. The stage could have split or broken apart, with one part falling in the ocean as monitored by the Space Force, and the other section now heading for the Moon. If so, China is likely denying this fact for propaganda reasons.

Northrop Grumman to launch new satellite serving mission in ’24 on Falcon 9

9:12 am

Capitalism in space: Northrop Grumman yesterday announced that it has awarded the contract for the first launch of its Mission Robotic Vehicle (MRV) — designed as a robot capable of installing multiple mission extension pods (MEP) on satellites — to SpaceX for a launch scheduled in 2024.

Once in orbit each MEP [Mission Extension Pod] is captured by the MRV and stowed for transport to the client satellite. The MRV rendezvous and docks with the client to install the MEP, which operates like an auxiliary propulsion device and uses its own thrusters to maneuver the client vehicle. Then the MRV detaches itself and moves on to grab another MEP for the next customer. The MRV is designed to stay in orbit for 10 years.

Anderson said the company expects to install as many as 30 propulsion pods over the life of the MRV.

“Our manifest for the MRV is full through mid 2026,” he said. Besides Optus, five other customers have signed term sheets to purchase mission extension pods.

Essentially, Northrop Grumman upgraded its Mission Extension Vehicle design to separate the repair section from the robot that installs it so that it is cheaper to launch everything. It can now launch multiple lighter and smaller repair pods as needed, with the robot already in orbit ready to go.

Deformed Martian craters

Deformed Martian craters
Click for full image.

Cool image time! The picture to the right, rotated, cropped, and reduced to post here, was taken on September 3, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The focus of the image for the MRO science team were the wedding cake layers inside the largest crater. These layers suggest glacial ice, with the layers suggesting multiple cycles of glacial ebb and flow. Since the crater is at 43 degrees north latitude, and sits in the chaos region dubbed Protonilus Mensae, smack dab in the center of what I call Mars’ glacier country, this conclusion makes perfect sense.

To my eye, however, the most interesting feature of this photo are the many distorted craters. The overview map below shows the picture’s location, as well as several nearby very large impact craters which might have caused many secondary impacts, including the many craters at this location.

Northrop Grumman launches Cygnus freighter to ISS

8:29 am

Capitalism in space: Northrop Grummann yesterday used its Antares rocket to successfully launch its Cygnus freighter to ISS.

This fact about this Cygnus is important:

This is the first Cygnus mission featuring enhanced capabilities to perform a re-boost to the space station’s orbit as a standard service for NASA; one re-boost is planned while Cygnus is connected to the orbiting laboratory.

In other words, Cygnus has been enabled to replace the boost capability that the Russians and Japanese provided.

The 2022 launch race:

6 SpaceX
2 China
2 Russia
1 Virgin Orbit
1 ULA
1 India
1 Europe (Arianespace)
1 Northrop Grumman

Virgin Galactic chairman resigns

8:54 am

Getting out while the getting is good: Chamath Palihapitiya, who has been chairman of Virgin Galactic’s board since it went public in 2019, suddenly announced today that he has resigned from the company.

Palihapitiya’s SPAC, or special purpose acquisition company, took Virgin Galactic public in October 2019. The company’s stock has faced volatile trading since then — climbing above $60 a share in the months ahead of Sir Richard Branson’s test spaceflight, but it recently fell below its public debut price on news of a further delay in the start of commercial service.

The now-former chairman sold his personal Virgin Galactic stake in early 2021 that was worth over $200 million at the time. But he indirectly owns about 15.8 million shares through Social Capital Hedosophia Holdings.

Like Richard Branson, Palihapitiya sold the majority of his stock when the price was high, about the time the company flew its first and only passenger flight in July, with Richard Branson on board. His exit now suggests he wants out before the company’s dismal future prospects become obvious.

Hugging galaxies

Hugging galaxies
Click for full image.

Cool image time! The Hubble Space Telescope science team today released the photo to the right, cropped and reduced to post here, of the interaction of three galaxies, the larger two of which look like they are hugging each other.

This galaxy triplet is estimated to be about just under 700 million light years away. It was taken as part of a program aimed at producing high quality images of strange looking galaxies.

Using Hubble’s powerful Advanced Camera for Surveys, astronomers took a closer look at some of the more unusual galaxies that volunteers identified. The original Galaxy Zoo project was the largest galaxy census ever carried out and relied on crowdsourcing time from more than 100,000 volunteers to classify 900,000 unexamined galaxies. The project achieved what would have been years of work for a professional astronomer in only 175 days and has led to a steady stream of similar astronomical citizen science projects. Later Galaxy Zoo projects have included the largest ever studies of galaxy mergers and tidal dwarf galaxies, as well as the discovery of entirely new types of compact star-forming galaxies.

If you want to do some real science, you should definitely check out the Galaxy Zoo webpage. Anyone can join in, using images produced by the Victor Blanco 156 inch (4 meter) telescope in Chile to find cool stuff that needs closer examination using better telescopes like Hubble.

Gehrels-Swift returns to science operations

2:13 pm

The Gehrels-Swift orbiting space telescope has returned to full science operations, after engineers determined the shut down on January 18th was caused by the failure of one reaction wheel and uploaded software allowing the telescope to function using only its remaining five gyroscopes.

In the last two decades satellite engineers have developed a range of software to allow spacecraft to point with acceptable accuracy using as few as two gyroscopes, even one in some circumstances. Thus, Gehrels-Swift has significant margin with five working reaction wheels.

You can now buy payload space on a lunar rover!

11:18 am

Capitalism in space: Lunar Outpost, which is building a mini-rover that will fly on the private Intuitive Machines lunar lander scheduled for launch later this year, has now partnered with the company Copernic to sell the rover’s spare payload space to whoever wants to buy it.

Lunar Outpost of Evergreen, Colorado, is preparing to send a 10-kilogram robotic rover to the moon on an Intuitive Machines lander and SpaceX Falcon 9 rocket later this year. While the lander’s primary payload is a Nokia LTE 4G technology demonstration, Lunar Outpost is working with Copernic Space to sell an additional 3.475 kilograms on its first Mobile Autonomous Prospecting Platform (MAPP).

…Copernic Space created the online platform to streamline the process of buying and selling space-related products and services like shares in a space startup, satellite sensor tasking or payload space. By applying blockchain technology, Copernic Space converts space assets into non-fungible or digital tokens, which are designed to be bought and sold online.

For the next 11 days, Lunar Outpost is selling a gram of payload capacity on its MAPP Lunar Rover for $4,250. The minimum order is 100 grams. In April, the public sale begins, allowing people to buy or sell as little as one-hundredth of a gram of payload space.

It appears purchase will be by using blockchain currency, and appears to also involve the purchase of “non-fungible or digital tokens”.

Normally I would applaud this effort, but the addition of these digital tokens makes the sale process seem less than straightforward and even a little suspicious. What exactly are customers buying? And what exactly will go to the Moon? Copernic’s website describes this process, but even there its seems exceedingly vague and uncomfortably like a con game.

From what I can gather, customers who buy payload space can use Copernic to create these non-fungible tokens which can then be resold to others to make back some of the cost. I wonder, however, why would anyone buy these tokens in the first place. As far as I can tell, they have absolutely no value in the real world.

Sierra Club official arrested for vandalizing Brownsville public mural with anti-SpaceX graffiti

11:02 am

Brownsville police today arrested Rebekah Lyn Hinojosa, a Sierra Club official, for spraying anti-SpaceX graffiti on the downtown mural painted by LA artist Teddy Kelly.

Hinojosa was taken into custody for spray painting the words “gentrified stop SpaceX” on a mural in downtown Brownsville. Hinojosa is the Senior Gulf Coast Campaign Representative for the Beyond Dirty Fuels Campaign, according to the Sierra Club website.

The level of ignorance illustrated by Hinojosa is difficult to measure. First, how can she think destroying art is no worse than “dirty fuels”?

Second, her belief that gentrification is somehow evil illustrates a truly profound close-mindedness and a refusal to notice that the prosperity that SpaceX is bringing Brownsville is helping everyone, poor and rich alike. She would be hard-pressed to find anyone who lives in Brownsville unhappy with SpaceX, if she made the slightest effort to ask — which she obviously does not wish to do.

Third, it appears she assumes her a short meaningless slogan constitutes a reasoned argument that will certainly change minds. And if she is right, we are truly doomed.

Hinojosa’s act however reveals the rising level of mindless hate against SpaceX’s achievements among the wine-and-cheese Democratic Party suburban crowd, the only people who really support leftist environmental organizations like the Sierra Club. They are beginning to marshal their forces to destroy the company, and sadly, their allies in the Democratic Party now control much of the government. At a minimum, expect serious delays at Boca Chica and with Starship due to this anti-capitalism campaign.

Hat tip to Robert Pratt of Pratt on Texas for letting me know about this story.

Astroscale about to resume space junk capture test

10:06 am

Capitalism in space: After several weeks of delay due to unstated technology issues, the Japanese company Astroscale has begun maneuvers in its test to see if its robot satellite can approach from a distance and capture a target satellite acting as orbital space junk.

The Japanese startup has started moving its 175-kilogram servicer spacecraft closer to the 17-kilogram client satellite ahead of deciding whether to restart the demonstration, Astroscale said in a social media post.

According to Astroscale, it has made “good progress in working through solutions to the anomalous spacecraft conditions that we identified with ELSA-d,” or End-of-Life Services by Astroscale-demonstration.

The company did not disclose the nature of the issue, when it could restart the mission or the distance between the two objects.

That no specifics have been stated, and that the company also says it is “keeping regulators and key partners updated on our status,” suggests that maybe the problem wasn’t technical, but bureaucratic. Maybe some Biden administration functionary got nervous, and demanded Astroscale slow down the test so that he or she could review what was happening.

This would not surprise me in the least, though I admit it is nothing more than some wild speculation.

Blue Origin’s CEO wants to build more suborbital New Shepard spacecraft

9:56 am

Capitalism in space: Bob Smith, Blue Origin’s CEO, declared yesterday that the company has more space tourist customers than it can fly on its single New Shepard suborbital spacecraft, and wants to build more to handle the potential traffic.

Jeff Bezos’ space company Blue Origin flew 14 people to space in 2021, and CEO Bob Smith on Thursday said the firm needs to build more of its New Shepard rockets to meet the demand from the space tourism market. “I think the challenge for Blue at this point is that we’re actually supply limited,” Smith said, speaking at the FAA Commercial Space Transportation Conference in Washington.

If true, this is good news, for the suborbital tourist market. It means there might be enough business for both Blue Origin and Virgin Galactic to survive and make money, at least for a few years.

At the same time, Smith’s focus seems wildly misplaced, since it is the orbital market, not the suborbital space tourism market, where the future lies, as well as the really big money. Putting tourists on short ten minute hops to space might be exciting right now, but very soon it will seem very passe, as more and more orbital tourist flights take place.

I wonder if anyone asked Smith about the status of Blue Origin’s orbital rocket, New Glenn, which remains untested and years behind schedule, all because.the BE-4 engine that will power it is also years behind schedule. It would be nice to know when the first flightworthy engines will be delivered to ULA, as well as installed on New Glenn. Those engines were promised more than a year ago, and are still not a reality.

Shetland spaceport in Scotland delayed

9:45 am

Capitalism in space: The proposed spaceport planned for the Shetland Islands in the United Kingdom is now delayed because a government planning committee has failed to put it on its schedule for discussion.

A spokesperson for SaxaVord UK Spaceport said the SIC has now confirmed to them that the application will not be on the agenda on Monday, and has given no clear indication when it will be discussed.

…The council’s development director Neil Grant said: “This is a complex planning application and recently there has been great deal of information flowing between the applicant, ourselves and statutory consultees. We are working hard to ensure this is presented to the planning committee for a decision as soon as possible.”

So there will be no confusion among my readers, this proposed spaceport is not the same as the Sutherland spaceport in Scotland, presently under construction. It is a competitor, and until recently faced opposition from environmentalists, who have now withdrawn their objections.

ESA dithers, forming committee to study concept of building its own manned capsule

9:37 am

My heart be still! The European Space Agency (ESA) has decided to create a committee to study the concept of building a European manned capsule so that it will no longer be dependent on either the U.S. or Russia to get its astronauts into space.

Aschbacher said a draft mandate for the new advisory group will be presented to ESA members at a March meeting of the ESA Council, with the goal for the group to start working immediately thereafter. The committee will prepare an interim report in time for the ministerial meeting in November, with a final report by next spring.

“It is clear that this group has to be independent and comprising mostly non-space experts,” he said, “because we really would like to look at various aspects of society from an economic point of view, a historical point of view, a geopolitical point of view.” That means including people such as artists and philosophers in the group to look at various aspects of exploration beyond science and technology. [emphasis mine]

The highlighted words illustrate the empty PR nature of this committee. It will not result in any European manned spacecraft at all. Instead, it will spend more than a year talking a lot about the wonders of space, and then produce a report repeating how wonderful space is and how Europe must be there.

The result? ESA will have wasted a year and not gotten itself one iota closer to having its own manned spacecraft.

If this hollow effort was the exception to the rule for Europe, there might be hope some political pressure could get the committee reformed and actually include engineers to develop a real design. That hope is in vain, however, because this is how Europe and ESA does everything. By the time ESA produces the first designs of this capsule, probably five to six years hence, it will be so out-of-date that building it would be a joke.

In a larger sense, this absurd committee and the top management at ESA and in the European Union that proposed it illustrate the overall bankruptcy of modern civilization’s entire management class. The people running governments worldwide are generally all do-nothing idiots, who talk a lot, waste a lot of money for their own aggrandizement, impose taxes and regulations on everyone else that makes the lives of ordinary people a misery, and fail in almost every project they undertake. We need only look at their panicked, dishonest, and failed global response to the Wuhan flu in the past two years for a prime example.

The official intellectual class that is running our governments worldwide are bankrupt. They need to be fired.

Firefly savior Max Polyakov gives away his stock

9:58 am

Capitalism in space: Forced by the Biden administration to leave the smallsat rocket company Firefly Aerospace because he is not a U.S. citizen, the billionaire Max Polyakov — who brought the company back from bankruptcy — has now sold his 58% share to the company’s founder, Tom Markusic for one dollar.

His announcement of this decision did not speak well of the federal government:

I am giving up for 1 usd consideration all my 58% stake in Firefly to my co-founder and partner Tom. Dear CFIUS, Air Force and 23 agencies of USA who betrayed me and judge me in all your actions for past 15 months . I hope now you are happy . History will judge all of you guys. Max love Ukraine and yes I have Ukrainian passport and I am Founder of Firefly !!! Bye my “bird” and at the end of the days I proud what I done for my Land soul and heritage !!!

While it is generally not a good idea to have a non-U.S. citizen controlling a rocket company, Polyakov’s record here was outstandingly positive, for the U.S. Moreover, the Ukraine is a strong ally of the U.S., or used to be. To force him out for no reason seems irrational. A more rational approach would have been for the government to insist on monitoring his actions closely, so that only if he appeared to be acting against our interests would it act.

Polyakov’s decision to give Markusic the company further proves his good will. Too bad we have now lost him.

FAA administrator, a Trump holdover, announces resignation

9:41 am

FAA administrator Steve Dickson yesterday announced that he will officially resign from the agency on March 31, 2022.

Dickson was appointed by President Trump in 2019 to a five year term, so his resignation now cuts his term short by two years.

Dickson gave as his reason for resigning a desire to spend more time with his family, the go-to explanation for every Washington official’s resignation. While this may be true, I can’t help wondering if friction and pressure from the Biden administration contributed to his decision.

For example, though Dickson’s record with private enterprise has been mixed, his record in connection with commercial space was mostly good, working to help the new launch industry prosper by keeping out its way as much as possible. This record was especially obvious with SpaceX’s operations in Boca Chica, where there was little regulatory effort to slow that work until Biden became president, and even then relatively little. It could be the Biden administration was unhappy with this approach, and was trying to force Dickson to regulate SpaceX more.

A new administrator, appointed by Biden, will certainly be less friendly. Based on most Biden appointees in the past year, the administration will likely want to put someone in place who is hostile to capitalism, favors a communist agenda, and wants to impose strong government control. Thus, this resignation almost certainly puts another nail in the coffin of SpaceX’s desire to launch Starship test flights from Boca Chica.

Then again, that new administrator would have to be approved by the Senate, and right now, based on the Senate’s 50-50 split between Democrats and Republicans, it will be difficult for the Biden administration to get a radical leftist approved. This difficulty will be further magnified by Biden’s horrible poll numbers as well as similar polls suggesting a bloodbath for Democrats in the mid-term November elections. For them to force through an extremist in this position now will not help those poll numbers.

I therefore predict the nominee put forth by Biden will likely mouth empty support for private enterprise during the confirmation hearings. If the Senate Republicans are fooled by this disingenuousness (something that has happened frequently), when confirmed that person will immediately act to impose the government’s will on most commercial operations, especially those by SpaceX.

EU advances proposal to build its own broadband satellite constellation

9:19 am

Capitalism in space? Despite negative assessments of the project by its own bureaucracy, the European Union has decided to move forward on a proposal to build its own broadband satellite constellation.

The board’s negative score was based on several factors, including a lack of “analytical coherence” about why the proposed constellation is the best solution to the problems it is intended to address about broadband access and secure communications, use of a “predetermined technical solution” that isn’t specified and a lack of a timetable. The board also raised concerns about the validity of the data the commission used to back the proposed constellation as well as climate impacts from deploying it.

According to E.U. rules, an impact assessment must receive a positive opinion from the Regulatory Scrutiny Board for it to proceed. If it receives a negative opinion twice, only the commission’s Vice-President for Inter-institutional Relations and Foresight, Maroš Šefčovič, can allow the initiative to proceed.

That was the case for the broadband constellation. “Because of the political importance of this Programme, the urgency of action and having the additional clarifications and evidence viewed as satisfactorily addressing the identified shortcomings and suggested specifications of the Regulatory Scrutiny Board, the Commission – also in the light of the agreement by the Vice-President for Inter-Institutional Relations and Foresight – has considered it opportune to proceed with the Programme,” the legislative proposal stated.

Except for a commitment to spend $6.8 billion, at the moment the proposal includes few details, including the type and number of satellites, what frequency they would use, what orbits they would be in, and who would build and launch them.

Based on the typical time schedule for other recent European projects, do not expect this constellation to launch for at least another decade, at which time it will be obsolete.

Chandra in safe mode

9:11 am

The Chandra X-ray Observatory last week experienced a loss of power that caused engineers to put the science instruments on the space telescope into safe mode while they investigate the problem.

No further information is presently available.

Chandra has been in orbit since 1999, and is now on an extended mission through 2025. It would be a great tragedy if it failed now, just as the infrared Webb telescope is about to begin operations. The two space telescopes are complementary.

Cracking ice on Mars?

Cracking ice on Mars?
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on December 7, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the MRO science team dubs “erosion of scalloped terrain” in the northern lowland plains of Mars.

The cracks invoke the polygon cracks one sees in mud as it dries. The circular feature suggests a buried crater whose shape is merely suggested because the cracks are conforming to the underground topography.

Are we looking at dried mud? Maybe, but more likely we are seeing a sheet of ice now sublimating away and cracking as it does so. If you look at the full photo you will see the cracked material also appears to drape itself over several nearby low ridges, something that seems more likely from ice than mud.

The overview map below also suggests this is a buried layer of ice.

China tests lunar orbital maneuvers using last in-space component of Chang’e-5 sample return mission

9:48 am

China appears to be using the last in-space component of its Chang’e-5 sample return mission, left in lunar orbit after the samples came back to Earth and the sample ascent capsule was sent crashing to the lunar surface, to test a variety of lunar orbital maneuvers that could be used in future missions.

Chinese engineers have apparently moved it from a near-Moon orbit to what is called a distant retrograde orbit (DRO), shifting back and forth from the Lagrange points on each side of the Moon with respect to the Earth. Though some spacecraft in the Artemis program are planned to use this orbit, this is the first time anyone has done so.

[S]pacecraft activity tracker Jonathan McDowell, also an astrophysicist at the Harvard-Smithsonian Center, told SpaceNews that he believes China is probably using the Chang’e-5 spacecraft gaining experience with astrodynamics. “They are using it as a toy to play around with. It is clearly useful as a stable lunar orbit for future missions, I just don’t think it’s a specific precursor.”

This activity is also par for the course for China. They have previously used other leftover lunar spacecraft to test different orbital maneuvers. The activity also confirms China’s determination to continue its exploration and settlement of the Moon.

OneWeb sued by businessman for not paying him

9:38 am

An American businessman with ties in Kazakhstan and who claims he used those ties to obtain permission for OneWeb to launch its satellites there has now sued OneWeb.

Giorgi Rtskhiladze, an American-Georgian businessman, claims that he was not paid for arranging space rocket-launch rights for OneWeb in Kazakhstan. The company received public funding in 2020 after filing for bankruptcy and winning the support of Dominic Cummings, then the Prime Minister’s most senior adviser.

The $30m claim, filed in New York, alleges that Mr Rtskhiladze successfully lobbied the Kazakh government to allow OneWeb to launch satellites from Kazakhstan and operate a ground station for its internet network but was not paid. Mr Rtskhiladze alleges that OneWeb defrauded him by keeping him engaged with Kazakh officials but then terminated his services only after he demanded payment. His work led to “hundreds of millions of dollars in value” for OneWeb, he claims.

OneWeb denies these claims entirely. The claims do appear suspicious because Russia was doing the launching, and it has a solid lease to do so with Kazakhstan. Moreover, it is very doubtful Kazakhstan would do anything to threaten those launches, considering Russia was making a lot of money from them and would not take kindly to such an action.

China wants a formal hot line with U.S. and its companies to avoid space collisions

9:30 am

China last week proposed that a formal method of communications be established between it and the U.S. and its companies in order to avoid space collisions.

The proposal was made after Chinese officials once again claimed that several Starlink satellites had threatened its space station, something U.S. officials dispute.

At a Feb. 10 press conference, Zhao Lijian, spokesman for China’s Ministry of Foreign Affairs, reiterated claims the country made to the United Nations in December that it had to maneuver its space station twice in 2021 to avoid close approaches by SpaceX Starlink satellites. “China was fulfilling the international obligation stipulated by Article V of the Outer Space Treaty by informing the U.N. of the Starlink satellites’ dangerous approach to the Chinese space station that threatened the safety of in-orbit Chinese astronauts,” he said according to a government transcript, adding that the “in-orbit Chinese astronauts were facing real and urgent safety threats.”

China filed its notice with the U.N., he said, after failing to hear U.S. officials. “After the incidents, China’s competent authorities tried multiple times to reach the U.S. side via e-mail, but received no reply,” he said.

The U.S. government, though, tells a different story. In its own note verbale filed with the U.N., dated Jan. 28 and published by the U.N.’s Office for Outer Space Affairs Feb. 3, the U.S. says it never heard from the Chinese government about the close approaches by satellites designated Starlink-1095 and Starlink-2305.

This cat-and-mouse game is not simply about avoiding collisions in space. China this year will launch two more modules to its space station, using its Long March 5B rocket. Unless it has completely redesigned the rocket (very unlikely), the core stage for both launches will come crashing uncontrolled to the ground, causing endless bad press for China. These claims by China appear to be a propaganda effort to improve its image prior to those launches.

Nonetheless, establishing a better lines of communications with China to avoid future collisions makes sense. Right now U.S. companies are forbidden by law from communicating directly with China, which makes resolving collision threats difficult if not impossible.

A rebranded Virgin Galactic to reopen ticket sales

9:14 am

Capitalism in space: Virgin Galactic today announced both a major rebranding of the company — significantly deemphasizing its links to Richard Branson — as well as a resumption of ticket sales for its suborbital flights.

Virgin Galactic opened ticket sales to the general public and rebranded itself today a week ahead of what promises to be another dismal quarterly earnings report. The company most recently reported to having 700 reservations for suborbital spaceflights, with plans to reach 1,000 later this year. Space tourism flights are currently scheduled for the fourth quarter of 2022.

Virgin Galactic’s battered stock, which opened at $8.93, soared by more than 29 percent to $10.50 on the New York Stock Exchange. The company is scheduled to report earnings (actually a loss) for the fourth quarter of 2021 on Feb. 22.

Tickets will cost $450K, with a $150K deposit required. It also appears that — in order to encourage sales — the company is capping present sales to the first 1,000 who provide the deposit. Since it has for years claimed it has 700 paying customers already, this suggests they are looking for only another 300 at this time.

Branson’s share in the company is now only about 11% — having successfully pumped and then dumped 80% of his shares — and it appears its management senses his name and the association with his Virgin Group now carries more negative than positive connotations. The new company logo for example shrinks the word “Virgin” so much that if you didn’t look close, you’d think the company was simply called “Galactic.”

Supernova remnant Cassiopeia A as seen by IXPE

NASA today released the first image produced from its new X-ray space telescope, the Imaging X-Ray Polarimetry Explorer (IXPE).

The photo to the right is that image, showing the intensity of X-rays coming from the supernovae remnant Cassiopeia A. From the caption:

Colors ranging from cool purple and blue to red and hot white correspond with the increasing brightness of the X-rays. The image was created using X-ray data collected by IXPE between Jan. 11-18.

Though Chandra also detects objects in X-rays, IXPE will also detect their polarization, or the way the rays are oriented as they travel through space.

Cool image time! The mosaic above, created from two photos taken by Curiosity’s left navigation camera and downloaded from the rover today, looks to the southeast across the small rocky valley the rover has been traversing for the past two months towards Mount Sharp.

The rover had entered this valley through the nearest gap on the left, then traveled uphill from the left to the right until it had passed behind the nearest dark ridge on the right. It then retreated and turned left, starting uphill through Gordon Notch, as shown in the overview map to the right.

On the overview, the white line marks Curiosity’s past travels, with red dotted line indicating its planned future route. The yellow lines indicate the approximate view in the panorama above.

For scale, Navarro Mountain is about 450 feet tall. The actual peak of Mount Sharp is blocked by the white front range to the left. The rover is presently still 12,600 feet below that peak, which sits to the southeast about 35 miles away.

Orbex installs launchpad at test site

10:50 am

Capitalism in space: Orbex has now completed the installation of the first launchpad build in Great Britain in more than a half century, and will use it for static fire tests of its Prime rocket.

Full ‘dress rehearsals’ of launch procedures for the Orbex ‘Prime’ rocket can now take place at the test site. Orbex Prime is a micro-launcher designed to transport small satellites weighing around 150kg to low Earth orbit. It will eventually launch from its ‘home’ spaceport at Sutherland in the North of Scotland.

Actual launches will occur on a different launchpad at Sutherland. Whether it will be this launchpad, moved to Sutherland, or a second new pad built at Sutherland, has not yet been decided by the company. Either way, according to earlier releases, the company is targeting that first launch before the end of the year. Since it took about two months to build this first launchpad and deliver it, the decision to build a second pad will not impact that schedule.

SpaceX begins filling methane tanks at Starship launchsite in Texas

9:32 am

Capitalism in space: SpaceX has begun the slow process of filling the storage tanks at its launchpad in Boca Chica with the methane that will be used by its Starship and Superheavy rocket once launched.

To fill the two existing tanks, which may store enough methane to fuel a stacked Starship and Super Heavy about 4/5ths of the way, SpaceX will need around 40-50 more tanker deliveries. Since last November, SpaceX has completed more than 320 liquid nitrogen and 200 liquid oxygen deliveries – equivalent to about 6700 tons (~14.8M lb) of LN2 [liquid nitrogen] and 4200 tons (~9.3M lb) of LOx [liquid oxygen]. If SpaceX maintains that average and focuses entirely on LCH4 [methane], the two horizontal tanks could be filled to the brim before the end of February.

Having a substantial amount of [methane] stored at the orbital tank farm will finally allow SpaceX to attempt the first major wet dress rehearsals (WDRs) and, more importantly, the first full static fires with flightworthy Super Heavy booster prototypes. Of course, a tank farm with full supplies of LOx, LCH4, LN2, and their gaseous equivalents is also a necessity for the first orbital Starship launch attempt, which has most recently slipped from a target of mid-2021 to no earlier than (NET) Q2 2022, pending regulatory approval.

The article also notes that the way SpaceX built two vertical methane tanks at the launchpad appears in violation of Texas regulations, and might either need a waiver from the state or be rebuilt in order to be used. Subsequently the company has added two horizontal tanks that conform to regulations, and it is these tanks it is now filling. More tanks however will have to be added to give it the fuel needed for launch.

Astronomers form lobbying group to block development on Moon’s far side

9:14 am

Lunar zone reserved solely for astronomers
Lunar zone reserved exclusively for radio astronomers

In order to allow them to someday in the future maybe consider the idea of possibly building space-based radio telescopes on the Moon, astronomers have now formed a new lobbying group to advocate the creation of a zone more than a thousand miles wide on the Moon’s far side where all future development will be forbidden.

The new committee is chaired by Claudio Maccone, an Italian SETI (search for extraterrestrial intelligence) astronomer, space scientist and mathematician. Maccone supports creation of a Protected Antipode Circle or PAC, a large circular piece of lunar landscape about 1,130 miles (1,820 kilometers) wide that would become the most shielded area of the moon’s far side.

“PAC does not overlap with other areas of interest to human activity,” he said. “PAC is the only area of the far side that will never be reached by the radiation emitted by future space bases located at the L4 and L5 Lagrangian points of the Earth-moon system.”

In view of these unique features, Maccone believes the PAC should be officially recognized by the United Nations as an international protected area, where radio contamination by humans is curbed, now and into the future.

In other words, these astronomers want to be given, for free, full ownership of the region in the center circle on the graphic above for future radio telescopes, even though at present they have no plans or projects to build such things.

Though the idea of creating a region protected from radio signals so that good radio astronomy can be conducted has merit, no one should have the slightest sympathy for this request by astronomers. Why should anyone give them this vast amount of real estate when astronomers have shown so little interest in building any telescopes in space, anywhere?

Only after the astronomical community finally proposes an actual radio telescope for installation at this site should this request be given the slightest attention. Before that, it is merely a stupid power grab by elitists who deserve nothing from nobody.
