This week in fascist academia

1:04 pm

The childish nature of modern American culture often gets me very depressed. Sadly, this depression is worsened by the fascist and intolerant culture that dominates much of America academia and that I have been noting with regular weekly reports since October. If our intellectual community acts like jack-booted thugs how can we expect our overall culture to be mature and civilized?

Anyway, here are a few more stories from the past week that unfortunately intensify my depression and the lack of enthusiasm I presently have for posting anything related to culture or politics. It all seems to be a cesspool, and horribly the academic community appears to relish the idea of swimming in it.

First, some stories indicating the close-mindedness and intolerance of the teaching community:

The second story is especially disturbing. The professor, Donna Riley, is head of the School of Engineering Education at Purdue. This is what she advocates for her school’s engineering program:

She claims that rigor can “reinforce gender, race, and class hierarchies in engineering, and maintain invisibility of queer, disabled, low-income, and other marginalized engineering students,” adding that “decades of ethnographic research document a climate of microaggressions and cultures of whiteness and masculinity in engineering.” She evens contends that “scientific knowledge itself is gendered, raced, and colonizing,” asserting that in the field of engineering, there is an “inherent masculinist, white, and global North bias…all under a guise of neutrality.”

To fight this, Riley calls for engineering programs to “do away with” the notion of academic rigor completely, saying, “This is not about reinventing rigor for everyone, it is about doing away with the concept altogether so we can welcome other ways of knowing. Other ways of being. It is about criticality and reflexivity.”

So, would you want to fly on a rocket built by engineers taught at Purdue, under this professor’s program?

Next we have stories that show that the intolerance is definitely not confined to the teachers, that the students are becoming as intolerant and as fascist.

A variety of geological activity caused bright areas on Ceres

10:33 am

Occator Crater

Based on the data obtained of Ceres from Dawn scientists have concluded that a variety of geological activities caused the bright areas on the planet, and that some of those activities could still be happening today.

Since Dawn arrived in orbit at Ceres in March 2015, scientists have located more than 300 bright areas on Ceres. A new study in the journal Icarus, led by Nathan Stein, a doctoral researcher at Caltech in Pasadena, California, divides Ceres’ features into four categories.

The first group of bright spots contains the most reflective material on Ceres, which is found on crater floors. The most iconic examples are in Occator Crater [shown in the image above, reduced and cropped to post here], which hosts two prominent bright areas. Cerealia Facula, in the center of the crater, consists of bright material covering a 6-mile-wide (10-kilometer-wide) pit, within which sits a small dome. East of the center is a collection of slightly less reflective and more diffuse features called Vinalia Faculae. All the bright material in Occator Crater is made of salt-rich material, which was likely once mixed in water. Although Cerealia Facula is the brightest area on all of Ceres, it would resemble dirty snow to the human eye.

More commonly, in the second category, bright material is found on the rims of craters, streaking down toward the floors. Impacting bodies likely exposed bright material that was already in the subsurface or had formed in a previous impact event.

Separately, in the third category, bright material can be found in the material ejected when craters were formed.

The mountain Ahuna Mons gets its own fourth category — the one instance on Ceres where bright material is unaffiliated with any impact crater. This likely cryovolcano, a volcano formed bythe gradual accumulation of thick, slowly flowing icy materials, has prominent bright streaks on its flanks.

The report is somewhat vague about why they think that there might be some geological activity even today.

The image above, released as part of this press release, gives us a simulated oblique look at Occator Crater and its bright areas. It is definitely worth it to look at the full resolution image.

Sea Launch will assemble rockets in U.S.

10:14 am

Capitalism in space: S7, the Russian company that now owns Sea Launch, announced today that it plans to assemble its rockets in United States.

This means the dock for the floating launch platform will remain in California. The article also indicates that S7 will continue to use Ukrainian Zenit rockets, which the platform was designed for, despite the desire of the Russian government to cut off all dependence on Ukrainian technology. There is also this tidbit:

The S7 company, which is about to resume the Sea Launch program, has enough clients, S7 Group co-owner and chair of the board of directors Natalia Filyova told the press. “We have [launch] orders, there is a long line [of clients], and we offer a good price. We are expecting revenue, but this will not happen right away. We will be investing heavily but we realize that we will make money,” Filyova said.

No details of the clients or the launch schedule were announced, however, so I remain skeptical. Meanwhile, Roscosmos announced today that it is negotiating with Boeing for future space tourism flights. This second story is directly related to Sea Launch, but you would only know this if you read Behind the Black. To pay off Boeing, which used to be a half partner in Sea Launch and was owed $320 million by the Russians, Roscosmos gave Boeing an unspecified number of seats on future Soyuz capsules to sell to others. Two of those seats were sold to NASA.

These new negotiations probably are an effort to arrange further sales for Boeing to help it get its money back. Boeing’s lawsuit for that money has placed a lien on the Sea Launch platform, and until its concerns are satisfied, S7 really can’t begin operations.

Negotiations underway to shift 1st stage landings at Kennedy to new site

9:58 am

Capitalism in space: Negotiations between the Air Force, NASA, and Space Florida (which runs the spaceport) have begun to establish a new location at Kennedy for 1st stage rocket landings.

The goal would be to lessen the burden landings impose on the Cape’s nearby industrial area, which workers must evacuate for hours during some missions. “If we have to stop operations for a launch during the middle of day, it is severely impacting to other customers,” Brig Gen. Wayne Monteith, commander of the Air Force’s 45th Space Wing, said Tuesday during a transportation conference at Port Canaveral.

As outlined in KSC’s master plan, the new landing pad could be built near the northern end of the spaceport’s secure perimeter — north of pad 39B and south of State Road 402 leading to Canaveral National Seashore’s Playalinda Beach. “We have land further to the north that’s not populated like the industrial area of the Cape is, and that might make for a really good location for a new landing zone for an increased landing rate,” said Nancy Bray, KSC’s director of spaceport integration and services.

I expect that SpaceX, should it be forced to shift landings from its just built landing sites, will also need to be in these negotiations since it will likely want some reimbursement for that work.

Rocket Lab pins down cause of launch abort

9:48 am

Capitalism in space: Rocket Lab has identified the cause of yesterday’s abort of its Electron rocket, and is ready to proceed tomorrow with the launch.

Rocket Lab says its launch yesterday was aborted due to rising liquid oxygen (LOx) temperatures feeding into one of the Electron’s nine engines. The launch attempt was aborted two seconds before lift-off from its range on Mahia Peninsula between Gisborne and Napier.

It says it will attempt to launch again tomorrow – after 2.30pm – and that the 17m rocket or pad equipment wasn’t damaged.

The company said the slight LOx temperature increase was a result of a ”LOx chill-down bleed schedule” that was not compatible with the warm weather.

This is not that different than the kinds of issues SpaceX experienced in its early launch attempts of both its Falcon 1 and Falcon 9 rockets. It appears that getting the temperature and pressure of the liquid oxygen right is critical, and requires some in use trials to figure it out. With SpaceX, they eventually were able to enhance the process enough to allow them to cool the oxygen to make it more dense and thus get more of it in the tanks to increase the rocket’s launch capacity.

Orbital ATK gets first FCC license approval for space repair mission

9:38 am

Capitalism in space: Orbital ATK has gotten its first FCC license approval for its Mission Extension Vehicle 1 (MEV-1) robotic space repair mission, set to launch late in 2018.

Space Logistics [a subsidiary of Orbital ATK] has a contract with fleet operator Intelsat of Washington and Luxembourg to provide in-orbit servicing with MEV-1 — the first in a proposed fleet of satellite servicers Dulles, Virginia-based Orbital ATK intends to build — with service beginning in early 2019.

In a public notice issued Dec. 8, the FCC authorized Space Logistics to use four different frequency bands for telemetry, tracking, and command (TT&C) of MEV-1 as the servicer completes post-launch maneuvers, reaches the graveyard orbit for decommissioned geostationary satellites some 300 kilometers above the geosynchronous arc, and attaches to Intelsat-901.

Space Logistics’ MEVs works by connecting to a satellite and taking over station-keeping, using fuel onboard the servicer to propel the satellite and extend its life. Most geostationary satellites are forced into retirement after 15 years or more due to a shortage of fuel. “It is in our plan for Intelsat-901 that at the end of the five-year life extension mission that we would return the IS-901 to the graveyard orbit and release them there. After that release the MEV would then proceed onto our next client,” Anderson said, adding that the next client has not yet been identified.

They will still need to obtain additional permits from both the FCC (for future operations) and from NOAA (because the spacecraft’s cameras, needed for docking, might also look at the Earth).

Why NOAA has this permitting power astonishes me, but then, in today’s government-run America, I probably should not be surprised. If we were trying to settle the west today we would likely have a whole range of government agencies requiring wagon train approval, route approval, and scheduling approval.

Ariane 5 successfully launches 4 European GPS satellites

9:27 am

Capitalism in space: Using its Ariane 5 rocket Arianespace yesterday successfully placed four European Galileo GPS satellites in orbit.

This is expected to be Arianespace’s last launch for 2017. The standings for the most launches in 2017 as of today:

27 United States
18 Russia
16 SpaceX
15 China
11 Arianespace

SpaceX and Russia each have two scheduled launches, while China has one. China however does not release information about all of its upcoming launches, so it might surprise us with more.

Saturn’s rings are very young

8:57 am

Data from Cassini’s last ring-diving orbits has now strengthened the hypothesis that Saturn’s rings formed very recently, just a few hundred million years ago.

Saturn acquired its jewels relatively late in life. If any astronomers had gazed at the sky in the time of the dinosaurs, they might have seen a bare and boring Saturn.

It was then that some sort of catastrophe struck the gas giant. Perhaps a stray comet or asteroid struck an icy moon, tossing its remnants into orbit. Or maybe the orbits of Saturn’s moons somehow shifted, and the resulting gravitational tug-of-war pulled a moon apart. However it happened, two new lines of evidence from Cassini make it clear that the rings were not around in the early days of the solar system 4.5 billion years ago, as scientists had long believed, says Jeff Cuzzi, a ring specialist at NASA’s Ames Research Center in Mountain View, California. “It rules out the primordial ring story,” Cuzzi says. “That’s what it looks like to me.”

At the moment there is no consensus on what might have caused the rings formation so recently.

Blue Origin successfully flies upgraded New Shepard capsule

8:48 am

Capitlism in space: Blue Origin yesterday successfully completed the first flight of its upgraded suborbital reusable New Shepard spacecraft.

Further details noted this test was called Mission 7 (M7), featuring a next-generation booster – powered by its BE-3 engine – and the first flight of Crew Capsule 2.0, a spacecraft that now features real windows, measuring 2.4 x 3.6 feet.

The test flight also carried 12 payloads and even a passenger – specifically an instrumented dummy brilliantly named “Mannequin Skywalker”.

Further details noted the flight time was 10 minutes and six seconds, launching at 10:59 a.m. CT from Blue Origin’s West Texas test site. The booster achieved Mach 2.94 on ascent & Mach 3.74 on descent. It again showed its landing skills, as shown on the video released by Mr. Bezos.

I have embedded the company’s video below the fold.
