Block 5 Falcon 9 first stage returns to port

9:35 am

SpaceX’s first Block 5 first stage for its Falcon 9 rocket, designed to fly a minimum of ten times, has returned to port after its first flight last week.

This is the most interesting detail revealed:

While not visible, the most significant improvements are likely to be found at the base of the first stage’s octaweb – now assembled with bolts instead of welds – in the form of a dramatically improved heat shield around its nine Merlin 1D engines (also upgraded, of course). One of the Falcon recovery technicians showed some exceptional interest in the shield and Merlins, likely documenting their condition in extreme detail to inform engineering reviews of the pathfinder rocket after its first flight test.

The pictures show those bolts quite clearly.

Mars cubesats take picture of Earth and Moon

12:36 am

One of the two MarCO cubesats heading to Mars on the first interplanetary cubesat mission, has taken its a picture of the Earth and the Moon.

NASA set a new distance record for CubeSats on May 8 when a pair of CubeSats called Mars Cube One (MarCO) reached 621,371 miles (1 million kilometers) from Earth. One of the CubeSats, called MarCO-B (and affectionately known as “Wall-E” to the MarCO team) used a fisheye camera to snap its first photo on May 9. That photo is part of the process used by the engineering team to confirm the spacecraft’s high-gain antenna has properly unfolded.

As a bonus, it captured Earth and its moon as tiny specks floating in space.

In a few weeks the two cubesats will make a mid-course correction, also the first time a cubesat has attempted such a thing.

Redactions in Strzok/Page texts reveal FBI/Justice is hiding something

9:12 am

Link here. Essentially, the author did a very careful review of the texts between anti-Trump FBI officials Peter Strzok and Lisa Page during the week in July 2016 when the FBI investigation into Trump-Russian collusion began. What he found was that the many redactions in the texts serve only to hide what was really happening, as well as the extent of involvement in the Obama White House.

It would be interesting to know what is in the emails that apparently clarify how the Obama administration divided responsibility for running the Trump-Russia investigation. Just like it would be interesting to know what is behind all the many redactions in these texts about how and why the Trump-Russia investigation got started.

On what basis has the Justice Department concealed passages and references to government officials from these significant conversations? Are Justice and the Bureau claiming that the redactions are necessary because the information is classified — even though we’re talking about communications between highly trained intelligence officials?

And if that is the claim, are they telling us that Hillary Clinton was investigated — and given a pass — for the unauthorized transmission of classified information by FBI officials who were themselves actively engaged in the unauthorized transmission of classified information?

Based on past revelations, when we finally see what was redacted I expect we shall discover that the redactions had nothing to do with national security and everything to do with hiding malfeasance and the abuse of power by the FBI, the Justice Department, and the Obama administration.

Rogozin to take over Roscosmos?

8:48 am

I wonder if he used a trampoline: Less than a week after Putin dumped Dmitry Rogozin from his cabinet, a story in the Russian press suggests he has been offered the job as head of Roscosmos.

Under the government-run centralized Russian system, it would not surprise me if Rogozin gets this job. With the government, no one ever gets fired, they merely get shuffled about from one job to another. Results are irrelevant.

Another delay for SLS

8:36 am

This really isn’t news: Work on the core stage for the first SLS rocket launch appears to face another three month delay, threatening the scheduled June 2020 launch date.

The article outlines in great detail the work being done on the SLS core stage, and where the delays might be coming from, while also being vague about what exactly is causing the delay.

It is unknown if the additional time for completion of final assembly of the whole rocket stage is based on the engine section, the other four elements, or continuing refinement of forward work. Most of the hardware and systems that will fly on EM-1 are being built for the first time and the procedures to connect the five pieces of the Core Stage together will also be attempted for the first time.

Of the five elements, the most recent news had the Forward Skirt near completion of its individual work by the end of the month. Work to cover the liquid oxygen tank with its Thermal Protection System (TPS) foam was in final phases, with the liquid hydrogen tank to follow behind it. The engine section and intertank elements continue to be outfitted with propellant lines, pressure tanks, avionics boxes, wiring, and other equipment.

Once complete, the elements will be assembled vertically in two stacks before a horizontal join of the halves of the rocket kicks off final assembly.

In fact, reading the article’s detailed description of the testing and assembly of SLS’s core stage struck me as incredibly slow-paced, so slow paced that it actually filled me with a sense of ennui. In the time they seem to need to only do an equipment review, SpaceX appears to have upgraded and flown a new version of its Falcon 9 first stage, while also redesigning a new core stage for its Falcon Heavy.

Europa water plume detected in old Galileo data

8:22 am

Using old Galileo data and new techniques of analysis scientists have uncovered a water plume on Europa that the spacecraft flew through in 1997.

Over the course of 5 minutes, spikes the spacecraft recorded with its magnetic and plasma sensors reflected the alterations that a veil of ejected water, from one or many vents, could cause in a region matching the telescope observations, they report today in Nature Astronomy. This indicates that a region of the moon potentially 1000 kilometers long could host such activity, though it is impossible to say whether this is a single plume or many, like the complex system of fractures and vents seen on Enceladus. Indeed, on its own, this evidence was too weak to tie to erupting water in a 2001 study describing it, the authors add, but it fits well with the Hubble and modeled evidence.

As indicated by the quote above, the result has a lot of uncertainty.

1984 at the University of Michigan

1:03 pm

Fascist academia: The University of Michigan has been sued by a free speech organization for its 1984-like rules that threaten students with punishment, even re-education camps, if they dare express any opinion that might offend its organized thought police.

As the lawsuit says, the university has created an “elaborate investigatory and disciplinary apparatus to suppress and punish speech other students deem ‘demeaning,’ ‘bothersome,’ or ‘hurtful’.” Yes, really: The student disciplinary code defines “harassment” as any “unwanted negative attention perceived as intimidating, demeaning, or bothersome to an individual”

…The university has its version of the Stasi and Orwell’s Thought Police — a “Bias Response Team” that investigates supposed “bias” complaints from offended students — students who can file their complaints anonymously. So if you are accused of wrongdoing, you don’t even have a right to confront your accuser — just like the former citizens of East Germany where the Stasi had literally hundreds of thousands of informers who could be your next-door neighbor or even a member of your own family. Or in this case, a student down the hall or from one of your classes.

If you think this Star Chamber process is limited to verbal speech, think again. Just like the electronic surveillance in Oceania, the “Bias Incident Report Log” posted by Michigan on its website shows that the Bias Response Team may come after you for what you do and say in “On-line/Social Media” communications including texts, emails, and Twitter.

The log also shows that the campus secret police — sorry, the Bias Response Team — also goes after “Off Campus” speech. So students aren’t safe anywhere. Their First Amendment rights are severely restricted, no matter what they are doing or where they are.

So a student may literally receive a knock on his door “from a team of University officials threatening to refer the student to formal disciplinary authorities” for something some unknown, anonymous informant alleges that he said, something the informant doesn’t like, or doesn’t agree with, or is uncomfortable with. Unless, of course, as the complaint says, the student agrees to submit “to ‘restorative justice,’ ‘individual education,’ or ‘unconscious bias training’.”

In other words, the only way a student may be able to avoid formal charges against meritless claims is by agreeing to submit to the academic equivalent of a communist-style “re-education” camp or brainwashing about the latest liberal fad like “unconscious bias.”

Read it all. It is pretty horrible, and makes me wonder why the state government is providing any funds to this fascist-run university. Time to shut it down.

Chaos on Mars

11:56 am

chaos terrain

Cool image time! The image on the right, cropped and reduced in resolution to post here, shows an area on Mars that geologists have dubbed “Chaos Terrain.” If you click on the image you can see the full image, which also includes several canyons oriented in what seem to be random directions.

I first heard this geological term for regions on Mars shortly after the first orbital missions circling Mars began taking images back in the 1970s. It applied to places where the terrain was hummocky, a crazy collection of hills forming no pattern at all. Earth does not really have such terrain.

The close-up to the right also shows that at least one of these hills is fractured, made up of several large pieces that have separated over time.

This image was part of the May 2nd image release from the high resolution camera on Mars Reconnaissance Orbiter. What makes it interesting is its location on Mars. The image below shows that location, indicated by a white cross.

Dozens killed, including armed terrorists, in Gaza border violence

9:08 am

They also call this cutting off your nose to spite your face: Dozens have been killed today in riots along the Gaza-Israreli border as thousands of Gazan protesters attempted to invade Israel.

More than 35,000 protesters amassed at a dozen locations along the security fence, with many engaging in skirmishes that pushed the death toll Monday to the highest in Gaza since a 2014 cross-border standoff between the militant group Hamas and the Jewish state, according to the Associated Press.

Gaza health officials told the news agency that 41 people so far have been killed in Monday’s violence, and at least 772 have been wounded.

The relocation of the embassy from Tel Aviv, a key campaign promise of President Trump, has infuriated the Palestinians, who seek east Jerusalem as a future capital.

“Moments ago, an IDF patrol foiled a bomb-laying attack by a cell of three armed terrorists near Rafah, close to the border,” the Israeli military said Monday. “This is a particularly violent protest point. The troops responded with fire at the terrorists. The terrorists were killed.”

You want to live in peace? You show others that you mean it. You want others to see you as violent and a killer? You do things that prove it.

These demonstrations prove the latter. In the seventy years since Israel’s founding, that nation has shown, time after time, that it is more than willing to work with the Arabs, the Palestinians, the international community, anyone, in order to establish peaceful relations with its neighbors. Israel even unilaterally walked out of Gaza in order to show the world and the Palestinians that they are willing to allow an independent Palestinian state to exist side-by-side with Israel.

The Gazans here once again prove that they are unready to do so. They only hate, and want to kill, emotions that are hardly a good foundation for a reliable peace treaty.
