Stratolaunch building its own rocket engine

Capitalism in space: Stratolaunch yesterday revealed details about its PGA rocket engine that it is developing in house.

The hydrogen-fueled PGA will produce 200,000 pounds of liftoff thrust. “When you try to do something like single stage to orbit, or in our case air launch, you really have to have hydrogen performance to make it happen,” Jeff Thornburg, Stratolaunch’s vice president of propulsion engineering, told Aviation Week.

Stratolaunch says that 85 percent of the manufacturing process will take advantage of additive-manufacturing techniques, also known as 3-D printing. That’s aimed at reducing the cost of engine production. “The propulsion team is currently in the process of manufacturing and testing prototype subscale and full-scale hardware,” Stratolaunch says. “The team has completed ignitor development, with injector testing currently underway. After this is completed, the team will perform a full-scale preburner test by the end of 2018.”

The engine is being designed to power the rockets and manned ferry that they also plan to build to be launched from the bottom of their giant airplane Roc.

It is clear now that they could not find anyone else willing to build these upper stages, and are now building them themselves. This means that SpaceX, with its Big Falcon Rocket, is now not the only company building a completely reusable system for gaining access to space.

Roscosmos head meets with Chinese

The head of Russia’s Roscosmos space agency, Dmitry Rogozin, held meetings this week with China, discussing possible future space cooperation.

Russia can’t really afford to do much right now on its own, but it also wants to negotiate the best deal it can with anyone it works with in space. These discussions are therefore specifically designed to give Rogozin some negotiating leverage when he meets with NASA’s head Jim Bridenstine on October 10.

New images from Hayabusa-2’s mini-bouncers

Three press releases from the Hayabusa-2 science team last night provide new images from the spacecraft’s MINERVA bouncers, presently on the surface of Ryugu, as well as new high resolution images from Hayabusa-2 during its recent close-in maneuvers.

The images from the first story also includes a ten second movie showing a very rocky surface with the sun moving across the sky. The last link shows the primary landing site candidate with two backup sites.

All told, these images suggest that Ryugu is nothing more than a rubble pile stuck together. If it was heading to Earth, it might be difficult to deflect it, as it might break apart caused by any stress.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Next Long March 5 launch delayed again?

There are indications in the Chinese press that suggest the next launch of China’s largest rocket, the Long March 5, will be delayed from its present November launch into 2019.

An online report by People’s Liberation Army Daily, a military newspaper, reports Lin Xiqiang, deputy director of the China Manned Space Engineering Office (CMSEO), as saying at a press conference in Beijing on Wednesday that the Long March 5B will not make its planned test launch in the first half of 2019.

“Due to the failure of the launch of the Long March 5 remote launch vehicle, the first flight of the Long March 5B carrier rocket will be postponed. The specific implementation time needs to be clarified after coordination with relevant departments,” Xiqiang said.

The November launch was to put up a test communications satellite. Should it slip into 2019, this would likely also cause delays in the launch of China’s first lunar sample return mission, Chang’e-5 (originally scheduled for 2017), the launch of China’s first Mars planetary mission in 2020, and finally the launch of the first module of China’s space station, also set for 2020.

All this once again indicates that the problems with Long March 5 were very serious, and might not yet have been addressed, even with a redesign of its engines.

SEC goes after Musk

The Securities and Exchange Commission today filed a complaint against Tesla in an effort to force Elon Musk out as head of the company.

The complaint filed by the Securities and Exchange Commission came after a last-minute decision by Mr. Musk and his lawyers to fight the case rather than settle the charges.

The filing by the SEC in federal court in Manhattan threatens to deal a severe blow to the Palo Alto, Calif., electric car maker. Its brand and Mr. Musk are closely intertwined, and analysts have said the company’s roughly $50 billion market value is driven by Wall Street’s appreciation for Mr. Musk’s vision and skill as an innovator.
SEC Sues Elon Musk for Fraud, Seeks Removal From Tesla

Tesla wasn’t named in the suit as a defendant, but the SEC is seeking to bar Mr. Musk, Tesla’s largest shareholder and its top executive, from serving as an officer or director of any U.S. public company. Tesla shares, which have been under intense pressure amid questions about the firm’s financial strength and Mr. Musk’s behavior, tumbled 9.9% to $277 in after-hours trading Thursday on Nasdaq.

This is very bad news for Tesla. However, it might be good news for SpaceX, as Musk has admitted to being very overworked. If he is forced from Tesla, he will have an enormous load removed from him.

ULA picks Blue Origin rocket engine for Vulcan first stage

Capitalism in space: ULA has chosen Blue Origin’s BE-4 rocket engine to power the first stage of its next generation rocket, which they are now calling Vulcan-Centaur.

Two BE-4 engines will be used to power the Vulcan first stage. The press release does not mention anything about how they plan to recover these first stages. Earlier announcements had said that they would separate from the rocket stage and parachute down to be capture before hitting the ground.

Local Texas city council votes to keep spaceport

The Midland, Texas city council today voted to renew its contract with the company managing its spaceport there.

The council voted 6-1 to renew its contract with SilverWing Enterprises, an aerospace consulting company that manages Midland’s spaceport license. The one vote came from Spencer Robnett, who has been public with his belief that the spaceport needs to be shut down.

“Yeah I don’t think it would ever have a chance in Midland,” Robnett said. “I do think the space business and space technology and aerospace sector is evolving. There’s a lot of money being invested in it by billionaires, Bezos, Musk, and Branson. Unfortunately we don’t have a billionaire in Midland chasing aerospace investment. We’ve got a small economic development corporation that takes direction from the city council.”

Robnett might have a point. Midland’s spaceport had been the base of operations for XCOR’s Lynx, and with XCOR bankrupt and gone there doesn’t seem to be a lot of interest by anyone else in flying any rockets from there. Part of their problem is their location, which is far from the coast and would likely limit the launch options in order to avoid populated areas.

The question has to be: What does Midland offer to rocket companies that other spaceports don’t? Until they can provide an answer to that question, the money the council is spending on this spaceport is probably going to waste.

NASA extends Chandra telescope operation to 2024

NASA has extended its contract with the Smithsonian Astrophysical Observatory in Massachusetts to run the Chandra X-ray Observatory through 2024.

In many ways the longevity of both Hubble and Chandra as well as other space telescopes has demonstrated the robustness of much in-space engineering these days. It suggests that when we finally begin building manned interplanetary spaceships we should have confidence they will operate reliably for long periods.

SpaceX gets contract to launch private lunar rover missions

Capitalism in space: SpaceX has won a contract for two launches of lunar rovers built by a private Japanese company.

Tokyo-based lunar-exploration startup Ispace has signed up for launches on SpaceX’s Falcon 9 rocket in 2020 and 2021. The first will carry a lunar lander into orbit around the moon, and the second aims to put one on the moon’s surface so it can deploy a pair of rovers, Ispace said Wednesday. “We share the vision with SpaceX of enabling humans to live in space, so we’re very glad they will join us in this first step of our journey,” Ispace Chief Executive Officer Takeshi Hakamada said in a statement.

SpaceX already has a contract for another private lunar rover, built by the Israeli company SpaceIL, that is set to launch as a secondary payload in December.

Both companies are former competitors in the Google Lunar X-Prize competition. Based on these contracts, as well as the pending launch of Moon Express’s private lunar rover on a Rocket Lab Electron rocket, it appears that private commercial planetary missions are about to become routine.

Millennials are staying married; thus divorce rate plummets

Good news the future’s children! New data shows that millennials are returning to more traditional marriage patterns, staying married longer and thus causing the divorce rate to plummet.

New data show younger couples are approaching relationships very differently from baby boomers, who married young, divorced, remarried and so on. Generation X and especially millennials are being pickier about who they marry, tying the knot at older ages when education, careers and finances are on track. The result is a U.S. divorce rate that dropped 18 percent from 2008 to 2016, according to an analysis by University of Maryland sociology professor Philip Cohen.

…the divorce rate’s decline isn’t a reflection of a decline in marriages. Rather, it’s evidence that marriages today have a greater chance of lasting than marriages did ten years ago. “The change among young people is particularly striking,” Susan Brown, a sociology professor at Bowling Green State University, said of Cohen’s results. “The characteristics of young married couples today signal a sustained decline [in divorce rates] in the coming years.”

The news is not all good. The drop in the divorce rate is partly there because of the non-stop behavior of baby boomers to get divorced, repeatedly. Their behavior warps the stats, and makes a mediocre marriage stat by Millennials appear better than it is. Nonetheless, the change in behavior between these two generations is a very good sign. And it will be an especially good thing for the innocent children that result from these more stable marriages, which in turn will be better for society as a whole. One of the reasons American culture has become more crude and unstable in the past few decades is strongly linked to the raising of children in broken homes. Give children a stable home and numerous studies have found they will grow up more stable and mature, and thus help make society itself more stable.

Mars Reconnaissance Orbiter spots Opportunity through dust

Mars Reconnaissance Orbiter has taken a picture through the fading Martian dust storm that spots Opportunity about halfway down Perseverance Valley in the rim of Endeavour Crater.

Engineers have been increasing the number of times per day they are attempting to communicate with the rover, so far all to no avail. The picture thus only really tells us that the storm is lifting and that MRO’s high resolution camera is operating normally after three months of limited picture taking because of the dust storm.

Australian agency pushes Australia to join NASA Gateway project

The new colonial movement: An Australian government agency, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), has put forth a space roadmap for that nation that includes a push for them to participate in NASA’s lunar orbiting Gateway project.

“And when you look at a moon base, the support systems of oxygen, water, food – and the general support systems around it – is something that nobody has ever done before,” he said. “When we looked around Australia, these are areas where Australia has as much skill as anyone else. Things like dry farming capabilities, remote mining capability, the fact that CSIRO perfected the titanium dust that you can 3-D print from … there are a whole range of things where we can potentially contribute.” It is an interesting fact that Australia has exceptional expertise in 3D printing titanium. This is even more interesting when you consider that on the moon – according to Dave Williams – there is an oxide that is very similar to titanium that could be reduced to a titanium dust, with oxygen as a by-product.

“Realistically, NASA will lead the whole thing. But they will be looking for partners, and the idea will be to identify which niche areas Australia should try to push its industry into, and try to get support for and to make it work,” he said.

Essentially, they are proposing that Australia get in on the Gateway boondoggle by focusing on and then offering to provide peripheral support services.

Much of this is bureaucratic twaddle, not to be taken too seriously. At the same time, it does outline for Australia areas where there are needs, and where their private space companies could make money.

Has Aerojet Rocketdyne lost engine race with Blue Origin?

Aerojet Rocketdyne financial documents suggest that it has given up the bidding competition with Blue Origin to supply a rocket engine for ULA’s Vulcan rocket.

The latest financial release from aerospace manufacturer Aerojet Rocketdyne reveals that the company spent none of its own money on development of the AR1 rocket engine this spring. Moreover, the quarterly 10-Q filing that covers financial data through June 30, 2018 indicates that Aerojet may permanently stop funding the engine with its own money altogether—a sign the company has no immediate customers.

Although Aerojet will continue to receive some funding from the US military through next year to develop its large, new rocket engine, this money won’t be enough to bring it to completion. Instead of having a flight-ready engine for use by the end of 2019, the filing indicates that Aerojet now intends to have just a single prototype completed within the time frame.

Essentially this means ULA will have no choice but to pick Blue Origin’s engine, unless the Air Force pulls its weight and demands it take Aerojet rocketdyne, even if that means a significant delay before Vulcan can launch.
