Two super-Earths found orbiting nearby red dwarf star

2:40 pm

Worlds without end: Astronomers have detected evidence of two super-Earths orbiting Gliese 887, only 11 light years away and the brightest red dwarf star in the night sky.

They used a technique known as “Doppler wobble”, which enables them to measure the tiny back and forth wobbles of the star caused by the gravitational pull of the planets. The regular signals correspond to orbits of just 9.3 and 21.8 days, indicating two super-Earths – Gliese 887b and Gliese 887c – both larger than the Earth yet moving rapidly, much faster even than Mercury. Scientists estimate the temperature of Gliese 887c to be around 70oC.

Because Gliese 887 is a very constant star, not very active, and with relatively few strong flares, they think these planets have a chance of retaining their atmospheres.

Be aware that these are like most exoplanets only candidate exoplanets. Until their existence is confirmed by other researchers, it is possible the detection is a false one.

Axiom hires European company to help build private ISS module

8:59 am

Capitalism in space: Axiom has hired the European company Thales Alenia, to build the habitation module of its commercial space station that will initially attach to ISS.

Axiom’s station modules will form a new section of ISS that will be able to operate independently, so that when ISS is decommissioned it can detach and remain operational in space.

That Axiom did not choose either Boeing (which I think built most of NASA’s ISS modules) or Northrop Grumman (which has been pushing an upgraded version of its Cygnus capsule as future station modules) is intriguing. I suspect with Boeing cost was the major reason, as Boeing’s modules are generally far too expensive. There also might be questions about that company’s quality control.

Why Northrop Grumman lost out however is unclear. Its Cygnus design is relatively inexpensive, and has clearly demonstrated that it works very reliably. obvious. Thales Alenia makes that Cygnus module for Northrop Grumman, so why buy it from the U.S. company when you can get it from the builder. (Thanks to reader Doug Booker for pointing out this obvious fact, one I had forgotten.)

Either way, this contract award gets us one step closer to truly private operations in space. Eventually competing private stations such as Axiom’s will replace government stations like ISS. That will in turn certainly lower costs and and increase innovation, which in turn will accelerate the development of the engineering required to build practical interplanetary spaceships.

This of course assumes we remain a free nation. Right now I have strong doubts.

India’s space agency creates new bureaucracy to encourage commercial space

8:44 am

The new colonial movement: In a televised speech yesterday, the head of ISRO, India’s space agency, outlined the steps they are now taking to encourage a new private commercial space industry, which appear centered almost entirely around the creation of a new bureaucracy.

Sivan announced in detail, reforms intended for the space sector, which were approved by the Cabinet Wednesday. The prime change, the ISRO chief said, is that the private sector will no longer be confined to just supplying components but will now be able to build and launch satellites and rockets, provide launch services, perform intensive research and developmental activities, participate in ISRO’s science and planetary missions, and offer space services commercially.

To facilitate the private sector presence in ISRO, the agency has launched the Indian National Space Promotion and Authorisation Centre (IN-SPACe), an independent nodal agency, Sivan said. “The agency will ensure safety, security, and quality, engage in monitoring space business activity, enable ease of business at low cost for private players, ensure permission and authorisation of private activities,” he said. “It will also act as a nodal agency for hand-holding and promoting private sector in space endeavours, aiding ISRO to share technical expertise and facilities.” [emphasis mine]

This might work, but I have my doubts. While the first paragraph in the quote above sounds great, the second quote kind of blows the wind out of the sails. Rather than letting their private companies operate independently, ISRO is going to supervise them closely. Under such conditions it is unlikely an independent space industry building cutting edge and risky new technology can truly prosper. If ISRO does not like what a private company wants to do, all it will have to do is simply not give them permission to do it.

Perseverance launch delayed two days

8:37 am

NASA and ULA have agreed to delay the launch of the new Mars rover Perseverance two days, from July 20th to July 22nd, because of “a contamination concern.”

NASA’s Mars rover Perseverance was scheduled to launch toward the Red Planet on July 20 from a pad at the Cape Canaveral Air Force Station in Florida. But a problem cropped up as engineers worked to encapsulate the rover in the nosecone of its Atlas V rocket, which was built by United Launch Alliance.

“NASA and United Launch Alliance are now targeting Wednesday, July 22, for launch of the Mars 2020 mission due to a processing delay encountered during encapsulation activities of the spacecraft,” NASA officials said in an update. “Additional time was needed to resolve a contamination concern in the ground support lines in NASA’s Payload Hazardous Servicing Facility (PHSF).”

This contamination likely relates to their effort to keep the rover free from Earth biology.

The official launch window closes on August 11th, though they can still launch as late as August 15th and get to their targeted landing site in Jezero Crater on Mars.

The press continues to lie about COVID-19 to generate fear

1:35 am

Daily U.S. Wuhan flu deaths as of June 24, 2020

They just won’t stop lying: If you have been reading the mainstream leftist press, you are probably now under the impression that the COVID-19 epidemic is once again raging across the land, destroying whole communities while spreading out-of-control everywhere because some Republican governors thought it was now okay to come out of hiding.

The CNN article at the link above is typical, reporting in lurid detail how multiple states across the country are now experiencing record levels of new coronavirus cases.

Oh my! We are all gonna die!

Not. What the CNN article completely failed to mention is the number of deaths from COVID-19 taking place during this rise in new cases. Are you curious why? Could it be because, though the number of people now infected with the virus has skyrocketed, the number of deaths has remained largely flat, as shown by the graph above (data source here). The past two days has seen a slight uptick, but that is entirely within the range of the weekly ups and downs caused apparently by low numbers recorded over the weekends.

I am not the only one to notice this strange dishonest reporting, Nor is CNN the only culprit. This article at Just News noticed the same thing in a Washington Post report.

Obama took lead from beginning on Flynn frame-up

1:07 pm

Newly released FBI notes from former FBI head James Comey now reveal that as of January 5, 2017 not only did Comey and Obama consider all of the phone calls by former national security advisor Mike Flynn to Russian officials to be entirely “legit”, Obama was involved and likely instigated from the beginning the framing of Flynn.

Comey’s notes describe the discussion at that January 3rd meeting, attended by Obama, Biden, Comey, then-deputy attorney general Sally Yates, and then-national security adviser Susan Rice, about Flynn and his calls. The notes describe this unfolding conversation:

Obama: “Make sure you look at things and have the right people on it.”

Obama again: “Is there anything I shouldn’t be telling transition team?”

Comey, in response: “Flynn[‘s calls to] Kislyak … appear legit.”

In other words, Obama instigated the frame-up, even though he and these other high government officials knew Flynn had done nothing wrong.

As noted at the link,

The [January 5th] meeting to strategize against the Trump administration included just a few key law enforcement principals. Their testimony about what transpired is sometimes in conflict. Yates claimed Comey brought up the Logan Act while Comey claims Biden cited it. Rice claimed Obama directed that the anti-Trump operation be run “by the book,” but Comey claimed Obama even directed which personnel to use.

All parties agree, however, on the main substance of the meeting, which was a discussion of how to target Flynn for his “legit” phone calls and withhold vital national security information from the newly elected presidential administration. [emphasis mine]

In other words, President Obama led an effort to frame an innocent man in order to lay the groundwork for overthrowing the legally elected Trump administration. Or to be blunt, Obama was leading a coup attempt, aided by major players in his administration, many of whom remained in place as enemy agents once Trump took over.

Such behavior is not merely illegal and despicable, it is outright treasonous.

A host of new solar systems

11:20 am

A gallery of baby solar systems

Worlds without end: Astronomers this month released a large collection of images taken during the past four years by the Gemini South Telescope in Chile of young stars that also have debris disks and are likely solar systems in the process of forming.

The image to the right, reduced slightly to post here, is only a sampling of the 26 disk systems found out of 104 young stars photographed. Go to the link to see some higher resolution examples.

Of the 26 images of debris disks obtained by the Gemini Planet Imager (GPI), 25 had “holes” around the central star that likely were created by planets sweeping up rocks and dust. Seven of the 26 were previously unknown; earlier images of the other 19 were not as sharp as those from GPI and often didn’t have the resolution to detect an inner hole. The survey doubles the number of debris disks imaged at such high resolution.

“One of the things we found is that these so-called disks are really rings with inner clearings,” said Esposito, who is also a researcher at the SETI Institute in Mountain View, California. “GPI had a clear view of the inner regions close to the star, whereas in the past, observations by the Hubble Space Telescope and older instruments from the ground couldn’t see close enough to the star to see the hole around it.”

The data strongly confirms most theories about planet formation in these debris disks, as one of the youngest stars did not have any gaps in its disk, suggesting no larger bodies had yet formed to clear out a region.

Appeals court orders hack judge to dismiss Flynn case

10:20 am

The DC Court of Appeals has ordered Democratic Party hack judge Emmet Sullivan to grant the Justice Department’s request to dismiss its case against former national security adviser Michael Flynn.

A three-judge panel on the U.S. Circuit Court of Appeals for the District of Columbia, in a 2-1 ruling, said the department’s decision to abandon the case against Flynn settles the matter, despite Flynn having reached a deal with prosecutors from special counsel Robert Mueller’s office to plead guilty to making false statements in connection with a now-discredited FBI probe into whether the 2016 Trump campaign colluded with Russia.

Having lost his prosecutor, Sullivan had tried as judge to take on that role himself to keep the case going. Such actions by a judge are beyond the pale, since judges are supposed to be the neutral arbiter in any legal proceeding. By taking sides in this unprecedented manner Sullivan should be impeached and removed from office. Don’t count on it however.

Note too that Sullivan was also the judge who managed the whitewash in the Awan case, allowing that guy to skate free despite clear evidence Awan acted as a spy for Pakistan while working as the IT expert in a number of Democratic congressional offices.

Made in Space purchased by venture capital company Redwire

10:06 am

Capitalism in space: Made in Space, which has specialized in developing 3D printing in space on ISS and elsewhere, has been acquired by a company dubbed Redwire that was created by a venture capital company.

AE Industrial Partners, a private equity firm, formally established Redwire at the beginning of June by combining two companies it had acquired, Adcole Space and Deep Space Systems (DSS). Both companies are best known as suppliers of spacecraft components and engineering services, although DSS has also developed a robotic lunar lander and is part of NASA’s Commercial Lunar Payload Services program.

“What we wanted to do with Redwire is take some of the traditional space heritage from the small, agile and innovative companies out there like Adcole and DSS and combine them with a true innovator,” said Peter Cannito, chief executive of Redwire, in an interview.

Made In Space, he argued, is that innovator. “The things that they’re doing are things that have never been done and really have the potential to change the economics of space,” he said. “That filled a key gap in our strategy.”

Though the companies under Redwire will for now operate separately, eventually they will combine under the Redwire name. Note too that the head of Made in Space is now the CEO of Redwire while its chief engineer is now Redwire’s chief technology officier, so this acquisition appears more like a partnership between companies that helps them all, rather than an acquisition.

SpaceX tests 7th Starship test prototype to failure

9:53 am

Capitalism in space: As they had planned, SpaceX has done a tank pressure test of its seventh Starship prototype to failure, destroying the prototype.

This was actually the second test to failure for this tank, which is testing a new stainless steel alloy. The first had only sprung a leak that could be repaired.

Deemed 304L, the type of steel is still readily available off the shelf and only 10-20% more expensive than the 301 alloy SpaceX has used to build all Starship prototypes up to SN7. The biggest change it brings to the table is improved ductility (malleability), particularly at the cryogenic temperatures Starship’s tanks will often be held at. By reducing brittleness, Starships built out of 304L steel should be able to fail far more gracefully by developing stable leaks instead of violently decompressing. In fact, the very same test tank destroyed on June 23rd demonstrated that capability perfectly when it sprung a leak during its first pressure test on June 15th.

During its first cryogenic pressure test with liquid nitrogen, SpaceX CEO Elon Musk revealed that the SN7 test tank managed to reach 7.6 bar (~110 psi) before it began to leak – technically satisfactory for orbital Starship launches with an industry-standard 25% safety factor. Thanks to the general flexibility of steel, including the new 304L alloy SN7 was built with, SpaceX was able to simply repair the leak it identified, readying the test tank for a second cryogenic pressure test barely a week later.

Below the fold are two videos showing this second failure. Unlike earlier tests using different alloys, the tank does not go flying hundreds of feet into the air. The rupture seems more gentle, if I can use such a word for such a failure.

They have another tank ready to go, so testing should proceed quickly even after this test failure. And they also are prepping the full scale #5 Starship prototype for testing, which if all goes well will include actual test hops.
