China gets failed satellite to proper orbit

9:19 am

A Chinese satellite launched in late September that failed to reach its designated orbit after deployment has now reached that correct orbit.

During the launch of the Chinasat 9A mission in June 2017, the Reaction Control System (RCS) of the rocket stopped working during the coast phase, which resulted in a sub-planned payload release. The satellite, however, used its onboard propulsion to reach the desired orbit even with the rocket underperforming.

In September the limited information released by China suggested the launch had been a success but the satellite failed after deployment. Based on this new information, the launch in September only became a success now, as the failure was in the rocket’s upper stage.

China has not revealed the purpose of this satellite, though it is part of a program known to launch satellites for testing cutting edge technology.

NASA document: Starship orbital flight in March ’22

9:11 am

Starship orbital flight date?
Click for full image.

According to a NASA proposal to observe and measure the temperatures on Starship’s thermal protection during its return to Earth from orbit, that flight is now tentatively scheduled for March ’22.

The graphic to the right highlights the pertinent language in the poster presentation.

It must be noted that the poster might not be telling us when Starship will first launch, but when the designers of the camera system will be ready to film. The two are different. Still, the slowdown in flight testing at Boca Chica by SpaceX since July suggests there may be some truth to this date. That date also seems more reasonable now in connection with the FAA’s regulatory pace, which still needs to provide the final approval of SpaceX’s environmental reassessment of its Boca Chica launch site.

It also seems to me that the March ’22 date would be very convenient for NASA, as it almost certainly guarantees that Starship will reach orbit after SLS, thus avoiding for the agency a very big public relations embarrassment. I would not be surprised at all if the Biden administration and NASA’s top administrators, led by Bill Nelson, are purposely pressuring the FAA to make sure that Starship orbital flight is delayed until after the first SLS test flight, now expected in the January/February time frame.

There is also the possibility that SpaceX’s targeted launch dates were unrealistically optimistic. The company had a lot of work it needed to do prior to launch on its orbital launch facility at Boca Chica, and that work could not go forward while test flights and static fire tests were taking place. Pausing those tests has allowed the launch facility work to move forward aggressively.

A Lucy solar panel on Lucy fails to latch properly after deployment

8:40 am

Partly deployed panel

Engineers at Lockheed Martin (the prime contractor) and Northrop Grumann (which built the panels) are now troubleshooting an issue with one of the solar panels on the asteroid probe Lucy, which failed to latch properly after deployment.

The NASA graphic to the right illustrates this issue, though the graphic might not accurately portray the exact circumstance at Lucy. To get more solar power, Lucy’s panels are larger, and thus were designed to unfurl like a fan rather than the more commonly used accordion design. One panel has not completed that unfurling.

NASA’s announcement tries to minimize the issue but this quote from the link makes it clear that this could be a very big problem.

It’s not yet clear whether the array in question is, in fact, fully deployed but not latched in place or whether it did not reach full deployment and is not generating the same amount of power as its counterpart. It’s also not yet clear whether Lucy can safely fire its maneuvering thrusters with an unlatched array.

Monaco’s government establishes “Bureau of Space Affairs”

9:27 am

Capitalism in space: Monaco’s government announced this week that it has created a Bureau of Space Affairs, aimed at encouraging commercial space operations within the country.

By setting up a ‘one-stop-shop’ for aerospace-related matters, and reporting to the Digital Platforms and Resources Department (under the authority of the Minister of State), the Principality is taking its first steps towards supporting the growth and development of these companies by streamlining administrative procedures, and will also act as the welcome office for any prospective aerospace-related businesses looking to set up in Monaco.

At the international level, the Office of Space Affairs will represent the Princely Government in the relevant international organizations, in co-operation with the Department of External Relations and Cooperation. The Office of Space Affairs will interact with its counterparts in other countries for knowledge sharing, to foster economic cooperation, and to benefit Monegasque companies in aerospace and related fields.

Such government agencies are popping up in third world countries worldwide, with almost all having goals focused on helping and encouraging the booming private commercial marketplace and attracting it to their countries. This is great news.

That these countries are also competing worldwide for this business is also great news. It will discourage them from trying to take control, as government agencies are wont to do and as NASA did in the U.S. in the 1970s. Instead, the competition will force them all to keep their bureaucracies as streamlined as possible, so as to attract as many businesses as possible.

Russian filmmakers safely return to Earth

11:59 pm

Capitalism in space: A Russian Soyuz capsule safely returned three Russian astronauts to Earth today, including the two filmmakers that spent the last twelve days filming scenes on ISS for a movie.

Russian actress Yulia Peresild and producer Klim Shipenko landed with cosmonaut Oleg Novitskiy of the Russian federal space corporation Roscosmos on Sunday (Oct. 17). The three descended aboard the Soyuz MS-18 spacecraft to a touchdown at 12:35 a.m. EDT (0435 GMT or 10:35 a.m. local time) on the steppe of Kazakhstan.

The landing concluded 191 days in space for Novitskiy, who wrapped up his stay on the station by playing a bit part in the movie Peresild and Shipenko were there to film. A joint production of Roscosmos, the Russian television station Channel One and the studio Yellow, Black and White, “ะ’ั‹ะทะพะฒ” (“Challenge” in English) follows the story of a surgeon (Peresild) who is launched to the station to perform emergency surgery on a cosmonaut (Novitskiy).

ULA’a Atlas-5 successfully launches the Lucy asteroid probe

6:08 pm

ULA’a Atlas-5 rocket early this morning successfully launched the Lucy asteroid probe on a 12 year mission to study eight Trojan asteroids over a period from 2025 to 2031. One tidbit about the mission is especially creative:

Scientists named the Lucy mission after the fossilized remains of a human ancestor, called Lucy by the scientists who discovered her in Ethiopia in 1974.

The leaders in the 2021 launch race:

36 China
23 SpaceX
17 Russia
4 Northrop Grumman
4 ULA

The U.S. and China are once again tied in the national rankings, at 36 each.

Thrusters on Soyuz docked to ISS fire improperly

10:00 pm

The thrusters on the Soyuz capsule to be used to return the two filmmakers and one Russian astronaut back to Earth on October 17th would not stop firing when they were supposed to during routine testing in preparation for undocking.

From the NASA announcement, which by the way buried this event in the announcement’s eighth paragraph:

At 5:02 a.m. EDT today, Russian flight controllers conducted a scheduled thruster firing test on the Soyuz MS-18 spacecraft that is scheduled to return to Earth Saturday night with three crew members aboard. The thruster firing unexpectedly continued after the end of the test window, resulting in a loss of attitude control for the International Space Station at 5:13 a.m. Within 30 minutes, flight controllers regained attitude control of the space station, which is now in a stable configuration. The crew was awake at the time of the event and was not in any danger.

Flight controllers are continuing to evaluate data on the stationโ€™s brief attitude change due to the thruster firing. NASA and Roscosmos are collaborating to understand the root cause.

According to the first link, the thrusters tilted the entire station 57 degrees from its correct orientation.

Not only do they not know why the thrusters did not shut down when commanded, they do not know why they eventually stopped firing. They suspect it was because the thrusters ran out of fuel, but this is not yet confirmed.

The Russians still plan to use this Soyuz to return the film crew in two days. The story does not say whether these thrusters are needed in any way to deorbit the capsule.

That’s the second uncontrolled thruster firing from a Russian spacecraft docked to ISS in less than three months. Yet, no such thing had occurred for many decades prior to this. In fact, the last such events that I can remember occurred in the 1960s.

Why such events are suddenly occurring now with such frequency is very concerning, to put it mildly. It brings to my mind the drilled hole in an earlier Soyuz capsule, a hole that was clearly drilled in Russia when the capsule was on the ground and then covered up so it was not detected until the capsule was docked to ISS. The Russians investigated, said they solved the mystery, but have never told anyone what that solution was.

To paraphrase Shakespeare, something is very rotten in Roscosmos.

California environment overregulation sole cause of shipping backup

3:32 pm

California environment regulations that ban the use of any truck more than three years old, essentially banning half of all fleet trucks and practically all small private truck companies, is the real cause of the shipping backlog that is piling up outside the ports of Los Angles and Long Beach.

This banning was established by a deal the EPA made with California in October 2020, when Trump was still president.

In effect, what this 2020 determination and settlement created was an inability of half the nationโ€™s truckers from picking up anything from the Port of LA or Port of Long Beach. Virtually all private owner operator trucks and half of the fleet trucks that are used for moving containers across the nation were shut out.

In an effort to offset the problem, transportation companies started using compliant trucks (low emission) to take the products to the California state line, where they could be transferred to non-compliant trucks who cannot enter California. However, the scale of the problem creates an immediate bottleneck that builds over time. It doesnโ€™t matter if the ports start working 24/7, they are only going to end up with even more containers waiting on a limited amount of available trucks.

Essentially, California is now holding the entire nation hostage. The backlog is only going to get worse. Moreover, the deal as designed favored big operations, such as Amazon, Walmart, UPS, FedEx, Samsung, The Home Depot and Target, because they can afford the extra costs of shipping to alternative ports. The small companies are essentially shut out.

So much for protecting the little guy, Mr. Trump. This highlights again Trump’s primary failure. He did not clean house when in office, and thus allowed the bureaucracy — clearly operating as agents of the Democratic Party — to double cross and stymie him at every opportunity.

Dry Martian chaos

Dry chaos on Mars
Click for full image.

On Mars, one of the most common kinds of landscape is called chaos terrain. Made up of mesas, buttes, and cross-cutting random canyons, this geology is not seen on Earth, and when first identified by scientists in early orbital pictures in the 1970s, it baffled them. While it is clear that some form of erosion process caused it, the scientists did not have enough data then to figure out what that process was.

Today scientists have a rough theory, based on what they now know about Mars’ overall geology and its climate and orbital history. The canyons of chaos terrain were originally fault lines where either water or ice could seep through and widen. See this January 2020 post for a more detailed explanation.

Most of the cool images I have posted of chaos terrain have been in places in the mid-latitudes that are covered with glaciers. See for example this December 2019 post of one particular mesa in glacier country, with numerous glaciers flowing down its slopes on all sides. That mesa is quite typical of all such mesas in the mid-latitudes.

Today’s cool image above, cropped to post here, takes us instead to the Martian very dry equatorial regions. The photo was taken on May 17, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and like mid-latitude chaos, it shows a collection of random mesas with canyons cut almost randomly between.

Unlike the mid-latitudes, however, there is no evidence of glaciers here. Instead, the canyons and mesa slopes are covered with dust, shaped into wind-blown dunes.

As always, the overview map below gives us some context.

Today’s blacklisted American: Fired from a school for having a “Keep America Great” bumper sticker

12:22 pm

Cancelled Bill of Rights
Doesn’t exist at the University of San Diego.

The new dark age of silencing: Nicholas Ratekin, a masters student at the University of San Diego (USD), was fired from a teaching position, and then booted from the school’s masters program, because he apparently had a “Keep America Great” bumper sticker on his car.

Ratekin is now suing the university for kicking him out without cause. More information here.

As part of the requirements for Ratekin to earn his masters at USD, he needed to also do some student teaching. To do so he got a job a local high school, Canyon Crest Academy. He also worked there as the head coach of the high school’s water polo team, leading the team to back-to-back championships in his first two years of coaching.

Apparently, Ratekin made it a point to avoid discussing politics, both at USD and at the high school. However, because of his bumper stick, his colleagues at both assumed he was a Republican and Trump supporter and began harassing him. They could not tolerate having anyone from a different political party working with them. It was be a Democrat or be nothing.
