Cassini successfully completes first dive between Saturn and its rings

8:14 am

The Cassini spacecraft has successfully survived its close flyby of Saturn, diving between the rings and the top of the planet’s cloud tops.

As it dove through the gap, Cassini came within about 1,900 miles (3,000 kilometers) of Saturn’s cloud tops (where the air pressure is 1 bar — comparable to the atmospheric pressure of Earth at sea level) and within about 200 miles (300 kilometers) of the innermost visible edge of the rings.

Cassini is beaming down its images and data now, with the images to be available later today.

Third reaction wheel on Dawn fails

7:33 pm

The third of four reaction wheels on Dawn failed on April 23, forcing the spacecraft to use its conventional thrusters to orient itself.

The team discovered the situation during a scheduled communications session on April 24, diagnosed the problem, and returned the spacecraft to its standard flight configuration, still with hydrazine control, on April 25. The failure occurred after Dawn completed its five-hour segment of ion thrusting on April 22 to adjust its orbit, but before the shorter maneuver scheduled for April 23-24. The orbit will still allow Dawn to perform its opposition measurements. The reaction wheel’s malfunctioning will not significantly impact the rest of the extended mission at Ceres.

This might shorten Dawn’s remaining mission, but since it is in its final days anyway, the loss will not be severe.

Report finds NASA spacesuit development over budget, behind schedule, and inadequate

7:29 pm

Government in action! A NASA inspector general report has found that NASA’s program for developing new spacesuit is behind schedule, over budget, and unable to provide the necessary spacesuits needed for the agency’s future projects.

NASA’s spacewalking suits are in short supply, and a replacement is still years away despite the nearly $200 million spent on new technology, the space agency’s inspector general reported Wednesday. A next-generation suit for spacewalking astronauts is needed for future space travel, including trips to Mars. But a lack of a formal plan and destinations has complicated suit development, according to the report . At the same time, NASA has reduced funding for suit development, putting more priority instead on space habitats.

According to the report, NASA is dealing with a variety of design and health risks associated with the spacewalking suits used by astronauts aboard the International Space Station. The suits were developed more than 40 years ago and intended for 15 years.

More here. Essentially, the suits NASA presently uses on ISS don’t work well, there aren’t enough of them left, and they are difficult to maintain because they were designed for transport up and down on the space shuttle. At the same time NASA’s entire program to replace these suits has been mismanaged so badly that no replacement suits are anywhere on the horizon,even after spending hundreds of millions of dollars.

I predict that the next new spacesuit Americans use will be built in less than five years for a tenth the cost, by private companies.

Ann Coulter has cancelled her speech at UC-Berkeley

11:15 am

The fascists win: Ann Coulter has cancelled her speech at UC-Berkeley, scheduled for April 27.

She cites as her reason for cancelling as the fact that the two groups that had sponsored her lecture had both cancelled that sponsorship out of fear of violence and the refusal of the university and the local government to provide protection. Their lawsuits against the university however will go on.

Regardless, this is now what urban California has become, a fascist state where expressing conservative views leaves you vulnerable to violence, with the local authorities working with the violent brown-shirted thugs to help them squelch freedom.

Bigoted professor to accept students in course based on race

9:04 am

Bigot: A professor at Pomona College in California has announced that she will give preferential treatment to “students of color” in deciding who can attend her class on geology.

“I encourage students who PERM this course to indicate how their background, experience, and/or interests could contribute to diversifying perspectives in the course,” she states in the flyer. “In resolving PERMs I will strive to identify students for whom the small-section setting has the potential to be of particular benefit,” she adds, stressing that “I am especially interested in seeing PERM requests from students of color, first generation or low-income students, international, and students early in their college career (first two years); such students are especially encouraged to apply” [emphasis in original].

Increasingly in the modern leftist-controlled academic community, it is becoming popular to treat whites in the manner that bigots treated blacks before the civil rights movement, oppressively and with contempt.

I must add that not only is this professor’s policy bigoted, it is almost certainly illegal. I wonder if Pomona College will take action against it. I suspect not, because after all, this is California, a place that considers the oppression and the squelching of free thought to be a good thing.

European push for more space regulations under international law

8:46 am

In the European space community and governmental circles, there appears to be a new push to revise the Outer Space Treaty, focused specifically on increasing the treaty’s regulatory power in the area of large satellite constellations and space junk.

This week [the city of] Darmstadt hosts a closed-door, governmental meeting of the Inter-Agency Space Debris Coordination Committee (IADC). Whether it was planned or not, the IADC is set to discuss a much-needed renewal of international space law, which is, experts admit, rather vague. But how far they will go is anyone’s guess.

…There is a palpable sense that the space community needs enforceable international laws and regulations, rather than – or merely to bolster – its current inter-agency agreements. They’ve served us so far, but few countries have actually signed up to them. That leaves a lot of wriggle-room, especially as space becomes increasingly commercialized.

Most of our space activities are governed by the Outer Space Treaty of 1967. It’s a short document that primarily seeks to ensure space operations are “peaceful” and for the good of all humanity. It is complemented by other agreements, including a set of documents on mitigating space debris. “We have a good, coherent set of justified rules and we don’t intend to alter them drastically,” said Christophe Bonnal of the French Space Agency, CNES, and the International Academy of Astronautics (IAA) in closing remarks last week. “But we will improve them at the IADC meeting to include mega-constellations.”

It appears to me that this is a push-back against Luxembourg’s recent announcement that it is going to request a renegotiation of the Outer Space Treaty to allow for property rights in space. What this article is advocating instead is that the treaty increase its control and regulatory power over private satellite constellations, which at present are not covered by the treaty.

Liberated Mosul districts reconnect with satellite television

8:34 am

This story from SpaceWatch Middle East outlines the effort by the Islamic State to block access to information in Mosul, and how the recent liberation by Iraqi forces has allowed citizens to regain access to satellite television and the internet.

This website by the way is an interesting one. It is based in Switzerland, and appears focused on covering the business of space from a European/Middle East perspective.

Cassini about to make first dive into Saturn’s rings

8:27 am

Cassini will make its first dive through a gap in Saturn’s ring today, and this link provides details.

Because that gap is a region no spacecraft has ever explored, Cassini will use its dish-shaped high-gain antenna (13 feet or 4 meters across) as a protective shield while passing through the ring plane. No particles larger than smoke particles are expected, but the precautionary measure is being taken on the first dive. The Cassini team will use data collected by one of the spacecraft’s science instruments (the Radio and Plasma Wave Subsystem, or RPWS) to ascertain the size and density of ring particles in the gap in advance of future dives. As a result of its antenna-forward orientation, the spacecraft will be out of contact with Earth during the dive.

The first images are not expected until mid-day tomorrow.

Latch blamed for Webb vibration test issue

6:03 pm

A latch that hadn’t closed properly has been identified as the cause of the anomaly that halted vibration testing of the James Webb Space Telescope in December.

At the committee meeting, Smith said the problem was tracked down to a latch designed to hold in place one of the wings of JWST’s primary mirror, which consists of 18 hexagonal segments. Those wings are folded into place to fit within the payload fairing of the Ariane 5 that will launch JWST, then deployed into place once in space. The latch, he said, consists of two plates with serrated teeth a few millimeters in size. “The thought is that the teeth, when they closed it, they didn’t quite seat,” he said. “So during the vibe [test], the teeth clapped together on the order of a millimeter or two, and that was what made the noise.”

Engineers were able to replicate the noise by placing the plates slightly out of alignment in the lab and subjecting them to similar vibrations, giving them confidence that was the cause of the anomaly.

I love how the Webb program manager also says that Webb is “on budget and on schedule.” That claim could only be true if you make believe that the budget was always $9 billion and the launch date was always supposed to be 2018 instead of the original $1 billion and 2011 launch date.

A look at some Israeli West Bank settlements

2:22 pm

As my regular readers know, I periodically take trips to Israel to visit family. When I return, I then post my impressions and what I have learned, thereby providing an eye-witness perspective to the Israeli-Palestinian conflict. Previous essays from earlier visits are as follows, with the first five from my 2013 visit and the last from my visit in 2014:

Map of the West Bank settlements that I have visited

Having just returned from another visit, I have some new impressions. Above all, I think it worthwhile to note that in all these visits, I have routinely stayed with relatives who live in West Bank settlements. In fact, I have now visited or stayed in five different settlements. The map on the right shows the locations of these settlements, marked with an X. If you click on the image you can see a higher resolution version.

Unfortunately, I do not remember the name of the settlement from my 2003 visit, though I know it was west of Hebron. It might have been Carmel, but I am not sure. I do know I have indicated its location with reasonable accuracy.

Regardless, there are a number of things we can learn from my visits. The largest settlements, Alon Shvut, Kiryat Sefer, and Beitar, are all close to the 1949 Armistice border. They are also all relatively close to Jerusalem and thus act for many as suburbs of that larger city. As I wrote in 2013,

Clemson administrator proposes that candidates be prescreened for ideology

9:09 am

Fascist: An administrator at Clemson University has proposed the student government consider prescreening candidates for the proper multicultural ideology prior to elections to prevent the wrong candidates from reaching office.

“So when it comes to this whole idea of intercultural competence, what would it look like to have a standard for if you’re going to be elected as an officer, or hold a seat within CUSG [Clemson University Student Government], that you have to demonstrate that you have a certain level of intercultural competence, before you’re allowed to take that office, or that seat,” Richardson stated, according to CUSG Senate’s public livestream.

The administrator, Altheia Richardson, Director of Clemson’s Gantt Multicultural Center, suggested that the student government could either prescreen the candidates, or demand that they be properly educated after winning, though she added that “I will say, once you’re in, it’s harder to hold people accountable for those things if it hasn’t been set as a standard before.”

In other words, this fascist doesn’t like the opinions of some people who have been freely and fairly elected to student government office, and wants to establish a system whereby she can prevent such people from ever obtaining office. How nice.

Cassini makes last fly-by of Titan

11:38 am

Cassini on April 21 made its last fly-by of Titan as the spacecraft is prepared for its final 22 orbits of Saturn.

The flyby also put Cassini on course for its dramatic last act, known as the Grand Finale. As the spacecraft passed over Titan, the moon’s gravity bent its path, reshaping the robotic probe’s orbit slightly so that instead of passing just outside Saturn’s main rings, Cassini will begin a series of 22 dives between the rings and the planet on April 26. The mission will conclude with a science-rich plunge into Saturn’s atmosphere on Sept. 15. “With this flyby we’re committed to the Grand Finale,” said Earl Maize, Cassini project manager at JPL. “The spacecraft is now on a ballistic path, so that even if we were to forgo future small course adjustments using thrusters, we would still enter Saturn’s atmosphere on Sept. 15 no matter what.”

The flyby zipped past Titan only a little more than 600 miles above its surface.

Former Obama official confirms climate data manipulation by bureaucrats

10:18 am

A former Obama official has confirmed that during the Obama administrations bureaucrats in the federal government routinely misused or tampered with climate data in order to promote the theory that humans are causing global warming.

Former Energy Department Undersecretary Steven Koonin told The Wall Street Journal Monday that bureaucrats within former President Barack Obama’s administration spun scientific data to manipulate public opinion. “What you saw coming out of the press releases about climate data, climate analysis, was, I’d say, misleading, sometimes just wrong,” Koonin said, referring to elements within the Obama administration he said were responsible for manipulating climate data.

He pointed to a National Climate Assessment in 2014 showing hurricane activity has increased from 1980 as an illustration of how federal agencies fudged climate data. Koonin said the NCA’s assessment was technically incorrect. “What they forgot to tell you, and you don’t know until you read all the way into the fine print is that it actually decreased in the decades before that,” he said. The U.N. published reports in 2014 essentially mirroring Koonin’s argument.

This story does not prove that human-caused global warming is not happening. What it does tell us, as have many other stories previously, is that we can no longer trust the data issued by federal government sources, and that a major housecleaning is necessary in order to make that trust possible again.

Whether Donald Trump is the president capable of doing that housecleaning remains an open question. Some of his actions suggest he is. Some suggest he is not. Overall, he appears a transitional figure who will begin that housecleaning in a relatively superficial way, but lay the groundwork for someone in the future who will push it through with much more success.

Refueling tests begin on Chinese test space station

8:04 am

China has begun the refueling tests between its first unmanned freighter, Tianzhou-1, docked to its test space station, Tiangong-2.

Refuelling tests began at 07:26 Beijing time on Sunday (23:26 UTC Saturday), monitored from the Beijing Aerospace Control Centre (BACC). The refuelling process involves 29 steps and will take five days to complete.

To allow refuelling to take place, the propellant tube and coupling components needed to be perfectly matched after docking, with a margin error of less than 1 millimetre, according to Tianzhou-1 deputy chief designer Chen Qizhong.

The mission involving the Tianzhou and Tiangong spacecraft was designed to prove on-orbit resupply and refuelling technologies and techniques necessary for safe, long-term operation of the Chinese Space Station, which will be permanently crewed by at least three astronauts.

“After refuelling is completed, the residual propellant needs to be drained off. In order to identify security issues during the draining process, it needs to go through a number of tests and verification,” Bai Mingsheng, chief designer of Tianzhou-1, told CCTV+

The article also provides a great deal of information on the station and the freighter.

19 federal agencies eliminated in proposed Trump budget

12:44 am

This article provides a clear and detailed list of the nineteen federal agencies that the Trump administration proposes to eliminate in the budget blueprint it issued last month.

The total budget for all these agencies is only $3 billion, so the cuts are only a mere drop in the bucket in the federal deficit. Still, it is a start, though I have doubts the Republicans in Congress will have the spine to follow through on these cuts, especially with the elimination of National Endowment for the Humanities, the National Endowment for the Arts, and the Corporation for Public Broadcasting. All three have essentially become propaganda operatives for the left and the Democratic Party, so there is good reason for Republicans to cut their funding. The problem is that the left will squeal like pigs if these cuts go through, and the ability of the Republican leadership to withstand that squealing has generally been nil.

Nonetheless, it is definitely worthwhile to read this list of agencies that are on the chopping block. Almost all of them have accomplished little with their funds, other than pay the salaries of the bureaucrats who run them. In the private sector they would be gone in a nanosecond.

Vector suborbital rocket test scrubbed

7:43 am

A suborbital test flight of Vector’s orbital rocket was scrubbed on April 6 when a sensor aborted the launch.

The next test flight is scheduled for May 3, after a test April 6 at the company’s test site near the Mohave Desert was scrubbed when a sensor caused an automatic abort, Cantrell said.

Engineers quickly determined the rocket was functional but the company decided not to launch after high winds kicked up. But the rocket is fine, he said, adding that failures are part of the testing process. “We blew a lot of stuff up, trust me,” he said.

The article is more focused on describing in detail the company’s overall status, its fund-raising effort, its future plans, its present operation. This tidbit about the test launch was buried in it. That the flight didn’t fly is not a bad mark on the company, at this point. However, they are under pressure to fly as soon as possible in order to demonstrate success, and delays work against them.

Donors and students fleeing Drexel University, home of genocidal professor

10:41 pm

Drexel University, faced now with loss of donations and students because the university took no action against a professor that called for the white genocide, the murder of police officers, and the squelching of the free speech rights of a conservative speaker, has finally opened “a special committee of inquiry” into the professor’s conduct.

It seems the public has decided that enough is enough.

“Numerous prospective students whom the university has admitted have written to the university stating that they will not attend,” [Drexel Provost Brian] Blake wrote, adding that “at least two potential significant donors to the university have withheld previously promised donations.” Indeed, Blake asserted that “the nearly unmanageable volume of venomous calls” that the administration received in the wake of the professor’s latest tweets even forced the school to “consider turning off its phones” for several days.

It appears from the story that Drexel, which initially poo-pooed Professor George Ciccariello-Maher’s comments, is now going to take a hard line. Whether they fire him or merely slap him on the wrist remains as yet unknown.

Normally, I oppose the firing or punishment of anyone for the things they say. At the same time, we are all personally responsible for what we say, and if you say things that are downright evil, you have to accept the consequences of those statements. Calling for genocide against whites and the murder of police officers to me fits very well the definition of evil. Ciccariello-Maher might have the freedom to say these things, but his university has no obligation to support him for doing so.

Berkeley mayor belongs to group that organized riots against Milo Yiannopoulos

9:33 am

Fascist: It now appears that the mayor of Berkeley, Jesse Arreguin, belongs to the group that organized the riots that shut down the lecture of Milo Yiannopoulos.

Berkley Mayor Jesse Arreguin was revealed to be a member of the anti-fascist group, By Any Means Necessary (BAMN), on Facebook. BAMN orchestrated the violence that shut down a scheduled lecture at UC Berkeley featuring Milo Yiannopoulos in early 2017. Arreguin is allegedly also friends with BAMN leader, Yvette Felarca, on Facebook.

They were also involved in the violent clashes earlier this month.

This might explain why the Berkeley police did so little during the first riots as well as during the violence that occurred on April 15 between pro-Trump and leftist demonstrators. In fact, there is even some evidence, not conclusive, that suggests the Berkeley police were helping the leftist demonstrators.

Meanwhile, Yiannopoulos has announced that he is planning a week long free speech event in Berkeley later this year. Good for him.

Airbus-Safran gets go-ahead to build first Ariane 6 test rocket

8:30 am

Capitalism in space: The European Space Agency (ESA) has given Airbus-Safran the go-ahead to build the first Ariane 6 rocket, which will be used for ground tests.

It is really important to recognize how this article illustrates the major things that have occurred in how Europe is builds its rockets. Note first that Arianespace is not mentioned at all, even though government bureaucracy has been in charge of ESA’s commercial business for decades. It is not in control any longer and is thus irrelevant. Note also that the design was created solely by Airbus-Safran, and that the only thing ESA did was approve it. The agency did not micromanage it, or revise it, or insist on changes, as would have been the case less than three years ago. Instead, it appears they essentially rubber-stamped it, leaving this work entirely to the private company, which in the end will operate and sell the rocket entirely for profit, while also providing ESA its needed launch vehicle.

At first glance, it appears that the ESA has adopted here the recommendations that I made in my policy paper, Capitalism in space:. In truth, they made these policy changes well before my paper was even written, which helps illustrates forcefully their universal correctness. If you want things built well and efficiently, you give people ownership of their work, you let them create it, and you get out of the way.

Or to use that forgotten word, you let freedom work its magic.

China’s first unmanned freighter successfully docks with test station

8:04 am

Tianzhou-1, China’s first unmanned space freighter, today successfully docked with that nation’s test station module, Tiangong-2.

Tianzhou-1, China’s first cargo spacecraft, which was launched Thursday evening from Wenchang Space Launch Center in south China’s Hainan Province, began to approach Tiangong-2 automatically at 10:02 a.m. Saturday and made contact with the space lab at 12:16 p.m.

The Tianzhou-1 cargo ship and Tiangong-2 space lab will have another two dockings. The second docking will be conducted from a different direction, which aims to test the ability of the cargo ship to dock with a future space station from different directions. In the third docking, Tianzhou-1 will use fast-docking technology. It normally takes about two days to dock, while fast docking will take only six hours.

This testing program by China is very well thought out. They are performing a whole range of docking tests, and they are doing it with an unmanned prototype station that well simulates the full scale station they eventually plan to build.

The Israeli finalist in the Google Lunar X-Prize is out of the running

10:19 pm

The Israeli team for the Google Lunar X-Prize, one of the five finalists, can no longer win the race because its SpaceX launch will not take place before the end of the year.

SpaceIL, formed by veterans of the Israeli tech sector, will not be able to launch by the year-end deadline set by the race’s organizers, according to Spaceflight Industries, the space transport company hired to carry the team’s spacecraft on a Falcon 9 rocket launch it purchased from SpaceX.

A Spaceflight executive tells Quartz that SpaceIL’s rocket is still in the launch queue but will be unable to launch before 2018, effectively scotching SpaceIL’s chance at the contest barring a last-minute extension to the deadline.

The article does a nice job of summarizing the situation for all five finalists, all of which appear to have problems that could prevent them from flying before the deadline at the end of 2018. It also notes that an extension could also be granted, as has happened twice before.

France settles union dispute in French Guiana

10:10 pm

The union strike that has stopped all Arianespace launches from French Guiana for the past month has been settled.

The article provides no details on the settlement itself. Instead, it outlines the company’s intention to complete all the scheduled launches they had planned for 2017.

Update: This story outlines the basic agreement.

It authorises an emergency relief plan of up to 2.1 billion euros, which includes funds for security, education, healthcare and business aid.

France had already approved 1.1 billion in aid for French Guiana at the beginning of April. The additional funds were offered to meet demands made by the collective and local representatives, who rejected the government’s initial offer.

France will prioritise the implementation of the spending plan, said Bareigts, who described the agreement as a “decisive day for the future of Guiana”.

Essentially, this is a payoff to the unions and group in French Guiana that organized the strike. I am sure a lot of the money will go for good purposes, but I am even more sure that a majority of it will simply end up in the pockets of the strike organizers, doing little to help the people of French Guiana themselves.

Trump signs commercial weather satellite bill

4:14 pm

Capitalism in space: President Trump today signed the new law that strongly encourages NOAA to begin using privately acquired weather data.

Among the bill’s provisions is language formally authorizing the National Oceanic and Atmospheric Administration to purchase weather data from commercial satellite systems. The bill authorizes NOAA to spend $6 million a year in fiscal years 2017 through 2020 for a pilot program of data purchases to evaluate the effectiveness of commercial data to support weather forecasting.

NOAA has already started such a pilot program using $3 million appropriated to the agency in fiscal year 2016. In September 2016, NOAA awarded contracts to GeoOptics and Spire, with a combined value of a little more than $1 million, for GPS radio occultation data.

These are only baby steps. At this time NOAA’s bureaucracy views commercial space the same way that NASA did back in 2004: it is a threat and also incapable of doing the job. Since NOAA today, like NASA in 2004, has been unable to do the job very well itself, its ability to argue against private space is limited. Expect the pressure to build for NOAA to hand over more and more of its weather-gathering work to private companies.

Mars rover update: April 21, 2017

Curiosity

Curiosity's position, Sol 1664 (April 10, 2017)

For the overall context of Curiosity’s travels, see Pinpointing Curiosity’s location in Gale Crater.

Since my previous February 14, 2017 update, Curiosity has worked its way through the dunes and has emerged, as planned at the head of what looks like a dry wash flowing down from Mount Sharp. At the time I had predicted that the science team would then have the rover make a beeline to Mount Sharp, following the smoothest route. That prediction is almost certainly wrong. Instead, the scientists are probably going to have the rover zig-zag its way south into the dry wash so that they can study the geology there. This is what they have been doing, as shown on the traverse map to the right, which shows Curiosity’s location through Sol 1664 (April 10). Ideally I expect them to want to check out the flow areas of the central parts of the wash as well as the contact point on either side where the color of the terrain changes from dark to light. This appears to be what they doing now, two weeks later, based on this update posted yesterday.

The 23 m drive on Sol 1673 put Curiosity alongside Murray bedrock blocks that appeared to be capped with a different material, with a darker color and smoother texture relative to the Murray
