Russian prosecutors indict four rocket engineers for Proton failure

7:17 pm

This won’t solve Russia’s problems: Russian prosecutors have recommended criminal charges against four rocket engineers for failing to properly calculate the right amount of fuel, resulting in a Proton launch failure.

According to the spokesman, Energiya department head Balakin, section head Martynov and his deputy Lomtev responsible for asdeveloping operational documentation failed to ensure that their subordinate, engineer Bolshigin, should timely adjust the calculation formula for resetting the fuel control system. “The document on the need for such adjustment was submitted to the organization’s relevant department but was written off by the engineer as fulfilled. As a result, the calculation formula remained unadjusted,” the spokesman said. “Subsequently, Balakin, Martynov, Lomtev and Bolshigin who knew for sure that the formula for the calculation of the fueling level contained incorrect data that could not be used during a rocket launch agreed operational documentation without pointing to a mistake in calculations,” the spokesman for the Prosecutor General’s Office said.

Putting these guys in prison is probably the worst thing the Russians can do. It will strike fear throughout their entire aerospace industry, causing all other engineers to take as few risks as possible, or leave the industry entirely. What the Russians should do is simply fire them, and reward those that noted the problem with promotions and increased pay.

In a truly competitive free market such a response will work, because even if the companies don’t reform themselves new companies will step forward to replace them. Russia however does not have a truly competitive free market, and so their only recourse is top-down bullying and threats. “Do it right or we will jail you!”

I should add that the company involved, Energia, has nothing to do with the recent corruption discovered in the construction of the upper stage engines for both Proton and Soyuz. That involved a different Russian company entirely.

How government wrecked the gas can

12:05 pm

Link here. This story should not surprise you. More important however are the article’s concluding words:

Ask yourself this: If they can wreck such a normal and traditional item like this, and do it largely under the radar screen, what else have they mandatorily malfunctioned? How many other things in our daily lives have been distorted, deformed and destroyed by government regulations?

If some product annoys you in surprising ways, there’s a good chance that it is not the invisible hand at work, but rather the regulatory grip that is squeezing the life out of civilization itself.

Almost all of the petty technological annoyances we struggle with today are the result of foolish federal regulation.

Hat tip John Harman.

Almost 200 federal workers to take “civil disobedience” class

9:50 am

One hundred and eighty federal workers have signed up to take “civil disobedience” class on how to resist the Trump administration.

Dozens of federal workers have reportedly attended a support group for civil servants that serves as a forum for discussing opposition to the Trump administration. Some federal employees have already expressed defiance against the Trump administration following a gag order, which has since been lifted, that restricted the Environmental Protection Agency and departments of Agriculture and Health and Human Services from contacting the press or posting about the administration on social media.

This will not end well for these federal workers, which in the long run will be good for the American public. These people are not qualified to work in the federal government, because they think they are there to tell us what to do, rather than work for the American taxpayer who pays their salary. They will “resist”, Trump will find out who they are, and then he will fire them.

The private weather industry moves forward

9:23 am

Link here. Key quote:

Early next month, aerospace start-up Spire Global of Glasgow, UK, will send a mini-satellite into space aboard an Indian government rocket. This ‘cubesat’ will join 16 others that are beaming a new type of atmospheric data back to Earth — and some scientists worry that such efforts are siphoning funding away from efforts to push forward the science of weather forecasting. Spire will begin providing observations to the US government on 30 April.

The probes track delays in radio signals from Global Positioning System (GPS) satellites as they pass through the atmosphere — a technique known as radio occultation. Researchers can use the data to create precise temperature profiles of the atmosphere to feed into weather-forecasting models — and eventually, perhaps, climate models.

Spire and its competitor GeoOptics of Pasadena, California, are participating in a pilot project announced in September by the US National Oceanic and Atmospheric Administration (NOAA), which is under pressure from the US Congress to determine whether it can cut costs by using commercial weather data. But scientists worry that such efforts are hampering the development of radio occultation. For years, they have sought federal funding for a project to advance the technique, but Spire and its competitors say they can offer high-quality data for a fraction of the price. [emphasis mine]

The quotes I have highlighted illustrate the hidebound leftist scientific opposition to introducing private enterprise into weather research. The article, published in the journal Nature, never once articulates in any way how these private efforts will hurt scientific research. What it does show is that the private effort will cost a tenth of the government effort while getting launched much faster. The money, however, will go to these private companies, and not the scientific factions that up until now have lived on the government money train.

The complaints here are the same as those I saw in NASA back about a decade ago when NASA first considered hiring private companies to provide it cargo to ISS. This is a turf war. NOAA is now being pressured by Congress to do the same: stop building big expensive weather satellites and buy the service for much less from the private sector. The scientific community sees this as a threat to its funding and is trying to stop it.

With Republicans controlling all three branches of the federal government I think this opposition will be fruitless, and we shall see the shift to private enterprise in weather data-gathering to accelerate.

Government-owned Alaska Aerospace considers second spaceport

9:02 am

The competition heats up: State-owned Alaska Aerospace is considering opening a second spaceport outside the state and closer to the equator.

Alaska Aerospace operates the Pacific Spaceport Complex Alaska. The Kodiak Island complex is capable of polar, sun-synchronous and high-inclination orbits, but does not support the equatorial launches that make up most of the industry demand. With the new launch facility, Campbell said having equatorial launches will give the corporation a competitive advantage and also bring more customers to Kodiak.

The state no longer funds the corporation, which has never made money. Still, it now has contracts with Rocket Lab and Vector Space Systems and this new move is an obvious effort to make itself more viable.

Recovered Falcon 9 first stage prepped for launch

8:53 am

The competition heats up: SpaceX on Tuesday revealed that last week it has completed the standard static fire testing of the recovered Falcon 9 first stage that it plans to relaunch in March.

A March launch would mean an 11-month turnaround, which is far from optimal, but understandable for the first time. SpaceX’s founder and chief executive, Elon Musk, has acknowledged the company must do better in the future if resuable flight is to become economically viable. He says the next—and likely final—iteration of the Falcon 9 rocket will be optimized for reuse. “Block 5 is the final upgrade of the Falcon architecture,” he tweeted earlier this year. “Significantly improves performance & ease of reusability. Flies end of year.”

It now seems likely that SpaceX will fly the landed boosters it currently has, at most once or twice, before retiring them, instead of multiple times. Although the company hasn’t elaborated on the problems with the engines, booster structure, or composite materials that have shown wear and tear after their orbital launches and returns, Musk is confident that changes to the Block 5 version of the rocket will solve the problem. “I think the F9 boosters could be used almost indefinitely, so long as there is scheduled maintenance and careful inspections,” he has said.

In other words, SpaceX has had — for the first time in history — the opportunity to inspect a number of used first stage rockets, and that precious knowledge is making it possible for them to upgrade the stage design to make future stages more hardy. In fact, those future stages won’t be stages, but reusable vessels that SpaceX could even name if it wished.

Plotting the interstellar path to Proxima Centauri

8:40 am

Scientists have calculated the slingshot route that Breakthrough Starshot’s tiny interstellar spacecraft should take in order to reach Proxima Centauri while also gathering the maximum scientific data while zipping past the binary stars of Alpha Centauri.

The solution is for the probe’s sail to be redeployed upon arrival so that the spacecraft would be optimally decelerated by the incoming radiation from the stars in the Alpha Centauri system. René Heller, an astrophysicist working on preparations for the upcoming Exoplanet mission PLATO, found a congenial spirit in IT specialist Michael Hippke, who set up the computer simulations. The two scientists based their calculations on a space probe weighing less than 100 grams in total, which is mounted to a 100,000-square-metre sail, equivalent to the area of 14 soccer fields. During the approach to Alpha Centauri, the braking force would increase. The stronger the braking force, the more effectively the spacecraft’s speed can be reduced upon arrival. Vice versa, the same physics could be used to accelerate the sail at departure from the solar system, using the sun as a photon cannon.

The tiny spacecraft would first need to approach the star Alpha Centauri A as close as around four million kilometres, corresponding to five stellar radii, at a maximum speed of 13,800 kilometres per second (4.6 per cent of the speed of light). At even higher speeds, the probe would simply overshoot the star.

While most of this is hardly revolutionary, this is still the first time anyone has done the hard math based upon a real mission concept.

SpaceX to double leased space at Los Angeles port

10:16 pm

The competition heats up: SpaceX has requested a doubling of its leased space the port of Los Angeles in order to facilitate the return of first stages launched from Vandenberg.

The Board of Harbor Commissioners will vote at its Thursday morning meeting on a deal to enlarge Space Exploration Technologies Corp.’s footprint at San Pedro’s outer harbor. The company hopes to lease 4.6 acres of land and water area along Berths 51 to 53 for $23,735 a month, plus insurance and any incidental costs.

In addition to extra space, the lease agreement allows the company to have berthing rights, install a chain-link fence around the property, build a concrete rocket-support pedestal, and add an office trailer, guard shack and portable restrooms, according to a staff report prepared for the commission.

According to the article, the increased space is needed because of the company’s plans to launch every two weeks from its pads at Kennedy and Vandenberg.
