Indecision at Virgin Galactic over engine design

In the heat of competition: Sources at Virgin Galactic suggest that the company has still not made up its mind on the type of engine it will use on SpaceShipTwo.

Messier sums up the situation perfectly:

The lack of clarity about SpaceShipTwo’s main propulsion system is highly unusual. It’s difficult if not impossible to think of another space project that was uncertain about its primary propulsion system after nearly a decade of development.

Increasingly I do not see this spaceship ever flying, which saddens me. They had a ten year head start over everyone else, and have squandered it.

An update on Sarah Brightman’s astronaut training

The competition heats up: New detailed photos of Sarah Brightman’s training for her September tourist trip to ISS have been released.

The photos appear to dispel the rumors that Brightman might be replaced with her backup tourist for the flight to ISS.

Some might consider this flight nothing more than a publicity stunt. While it surely is that, for Brightman it also is a dream come true. And the publicity will not simply be good for her career, it will do wonders to sell the idea of space tourism and space exploration.

In fact, there is never really any downside to freedom and allowing people to follow their dreams, and this tourist flight to ISS will prove it.

New Shepard makes its first test flight

New Shepard launch

The competition heats up: Blue Origin completed on Wednesday its first test flight of its reusable suborbital spacecraft, New Shepard.

After reaching an altitude of 307,000 feet, or 58 miles, the capsule successfully separated from its first stage, what they call the propulsion module, and safely parachuted back to Earth. The first stage, designed to also be recoverable, was not recovered successfully. According to Jeff Bezos’s explanation, they “lost pressure in our hydraulic system” and that they were trying to land it vertically, like SpaceX’s Falcon 9 first stage.

The cropped image on the right of the full resolution image, gives us a close-up of the capsule and propulsion module. The small fins on the propulsion module suggest the capability for a vertical landing, but it is unclear from the image whether the module has legs, though other images and videos strongly suggest there are legs on this module.

The flight itself, getting above 50 miles, reached space according to most definitions. In fact, Blue Origin with this flight has accomplished what Virgin Galactic has been promising to do for more than a decade, a suborbital test flight of its spacecraft. Blue Origin’s flight was unmanned, but it demonstrated that their design works. They will of course have to re-fly the capsule as well as land that first stage successfully to prove the design’s re-usability, but this flight shows that they are off to a very good start. And their webpage clearly shows that they are almost ready to start selling tickets for suborbital flights.

The most significant success of this launch, however, is the performance of the BE-3 rocket engine. Blue Origin has convinced ULA to hire it to build the engines for its new Vulcan rocket. This success justifies that decision.

I have embedded their videos of the full flight below the fold.

“American cities are by and large Democratic-party monopolies [and] the results have been catastrophic.”

Link here. As the author bluntly notes, in referencing Baltimore in particular,

Yes, Baltimore seems to have some police problems. But let us be clear about whose fecklessness and dishonesty we are talking about here: No Republican, and certainly no conservative, has left so much as a thumbprint on the public institutions of Baltimore in a generation. Baltimore’s police department is, like Detroit’s economy and Atlanta’s schools, the product of the progressive wing of the Democratic party enabled in no small part by black identity politics. This is entirely a left-wing project, and a Democratic-party project.

When will the Left be held to account for the brutality in Baltimore — brutality for which it bears a measure of responsibility on both sides? There aren’t any Republicans out there cheering on the looters, and there aren’t any Republicans exercising real political power over the police or other municipal institutions in Baltimore. Community-organizer — a wretched term — Adam Jackson declared that in Baltimore “the Democrats and the Republicans have both failed.” Really? Which Republicans? Ulysses S. Grant? Unless I’m reading the charts wrong, the Baltimore city council is 100 percent Democratic. [emphasis mine]

Like Detroit, Atlanta, St. Louis, Chicago, and a host of other major metropolitan cities that are disasters for the middle class and the poor, Baltimore has been run by Democrats as a one-party monopoly for literally generations. The disasters we are seeing there have nothing to do with Republican policies, and everything to do with the terrible and failed policies of the progressive left. They are to blame, but they keep trying to spread that blame around.

It is time for Americans to see them for what they are — failures — and to stop voting for them. Republicans certainly don’t have all the answers, and should certainly be fired quickly if they fail to serve the public, but Republicans also have had nothing to do with the failures of the inner cities.

The most important thing a free person has is the freedom to choose. I pray that inner city Americans, both black and white, finally realize that it is time to choose differently.

Next Falcon 9 launch set for Monday

The competition heats up: The next commercial Falcon 9 launch is now set for tonight, Monday, less than two weeks after the last Falcon 9 launch.

The next two weeks will be especially busy for SpaceX, as they also have scheduled the first launch abort test of Dragon on May 5. The launch will also be the fifth for Falcon 9 this year, putting it in the lead as the busiest rocket in the world for 2015, ahead of the Russian Soyuz.

Seven big failed environmentalist predictions

Link here.

Like the author, I remember every single one of these doomsday predictions. I also remember how every single one of these predictions was wildly wrong. Until these fear-mongers can reliably predict things, I see no reason to believe them.

His article however does provide one entertaining tidbit:

You know how old I am? I’m so positively ancient that I remember when one of Jimmy Carter’s big answers to the impending shortage of oil was to increase federal funding for research on how to extract oil from shale. It ended the way you would expect: it went nowhere. But some decades later, private oil companies did find a way to more economically extract oil from shale—and environmentalists promptly made it public enemy #1.

All true. And just one more example of how the government fails at something while private enterprise, fueled by the profit motive, finds a way to make that exact same thing happen.

The building rage is not just against Democrats

People who read my website only intermittently might get the impression that I am partisan and specifically hostile to the Democratic Party. This is false. I am an equal opportunity opponent to anyone that likes oppression and the use of government to impose it.

Some stories today, describing the actions or opinions of some of the so-called conservative or moderate leaders of both the Republican and Democratic parties, illustrate clearly that we still need a major house-cleaning in Congress if we are to get this out-of-control monster under control:

NASA ISS cargo contracts delayed

The competition heats up: NASA has delayed, for the second time, when it will award its next round of cargo contracts to ISS, pushing the date back from June to September.

Though agency officials said they could not reveal why they had delayed the contract awards, they did say it was to gather more information. My guess is that the agency wants to see how SpaceX’s launch abort tests turn out this year before it makes a decision. If successful, they will then have the option of dropping SpaceX’s as a cargo carrier and pick someone else, possibly Dream Chaser, to provide up and down service to ISS. That way, they would increase the number of vehicles capable of bringing people and supplies up to ISS.

Delaying the award decision until September gives them time to evaluate the abort tests results, as well as give them a cushion in case those tests get delayed somewhat.

Liberals may regret their new rules

Link here. Two quotes:

Which brings us to America in 2015. It’s becoming a nation where an elite that is certain of its power and its moral rightness is waging a cultural war on a despised minority. Except it’s not actually a minority – it only seems that way because it is marginalized by the coastal elitist liberals who run the mainstream media.

Today in America, we have a liberal president refuses to recognize the majority sent to Congress as a reaction to his progressive failures, and who uses extra-Constitutional means like executive orders to stifle the voice of his opponents. We have a liberal establishment on a secular jihad against people who dare place their conscience ahead of progressive dogma. And we have two different sets of laws, one for the little people and one for liberals like Lois Lerner, Al Sharpton and Hillary Clinton, who can blatantly commit federal crimes and walk away scot free and smirking.

Today in America, a despised minority that is really no minority is the target of an establishment that considers this minority unworthy of respect, unworthy of rights, and unworthy of having a say in the direction of this country. It’s an establishment that has one law for itself, and another for its enemies. It’s an establishment that inflicts an ever-increasing series of petty humiliations on its opponents and considers this all hilarious.

That’s a recipe for disaster. You cannot expect to change the status quo for yourself and then expect those you victimize not to play by the new rules you have created. You cannot expect to be able to discard the rule of law in favor of the rule of force and have those you target not respond in kind.

And this:

When you block all normal means of dissent, whether by ignoring the political will of your opponents or using the media to mock and abuse them, you build up the pressure. In 30+ years as an active conservative, I’ve never heard people so angry, so frustrated, so fed up. These emotions are supposed to be dissipated by normal political processes. But liberals are bottling them up. And they will blow. It’s only a matter of how.

Liberals need to understand the reality that rarely penetrates their bubble. Non-liberal Americans (it’s more than just conservatives who are under the liberal establishment’s heel) are the majority of this country. They hold power in many states and regions in unprecedented majorities. And these attacks focus on what they hold dearest – their religion, their families and their freedom.

What is the end game, liberals? Do you expect these people you despise to just take it? Do you think they’ll just shrug their shoulders and say, “Well, I guess we better comply?” Do you even know any real Americans? Do you think you’ll somehow be able to force them into obedience – for what is government power but force – after someone finally says “Enough?

Read it all. I can’t quote it all, but every word carries a wisdom that the left — as well as the status quo Republican establishment — better heed before it is too late.

As I’ve said before, the rage is building.

I am also reminded of this scene, below the fold, from the 1966 masterpiece A Man for All Seasons:

Protesters prevent minorities from attending class

Fascists: In order to protest what they preceive as a hostile environment on campus for minorities, protesters blocked access to the school so that minorities could not attend classes.

Up to 50 students gathered and prevented foot traffic through the gate. On multiple occasions, students, including minorities, tried to break through so they could attend class. In response, the protesters violently attacked them. Three assaults were reported during the protest. The University of California Police Department (UCPD) at Berkeley did not take action against the protesters, despite the fact that they acknowledged that protesters were breaking the rules and potentially committed crimes.

You can’t make this stuff up. To highlight oppression these fascists impose oppression. According to the article, the protest only ended when students teamed up and “bull-rushed” the protesters in order to get to their classes.

Japan to the moon!

The competition heats up: Japan’s space agency has announced plans to send an unmanned lander to the Moon, as early as 2018, as part of a longer range plan to explore Mars.

They also intend to use their new Epsilon rocket to launch it.

Gee, I wonder if the successful efforts of India and China to send probes to both the Moon and Mars had some influence on this decision.

Sierra Nevada and Germany sign agreement

The competition heats up: Sierra Nevada has signed a new development agreement with Germany in connection with its Dream Chaser reusable mini-shuttle.

The agreement does not appear to involve any money and thus is largely symbolic. Nonetheless, it shows again that Germany is interested in having Dream Chaser built, and is throwing its support behind the manned spacecraft.

SpaceX is considering a ground landing for its next first stage return attempt

The competition heats up: After its second attempt this week to land its first stage on a barge in the Atlantic, SpaceX is now considering landing their next attempt on the ground.

This shouldn’t be a surprise. The reason they have been landing over the ocean in these initial tests was for safety. The last two landings however had demonstrated that they can reliably bring that first stage back accurately and precisely. Since they have the ability to destroy the stage should it go off course, it seems reasonable to shift to land now and simplify their challenge.

Stratolaunch considers multiple rockets for its giant airplane

The competition heats up: Stratolaunch is now considering widening its options for the upper stage that can be attached to its giant airplane.

[Chuck Beames, president of Seattle-based Vulcan Aerospace, the parent company of Stratolaunch Systems] said the interest in alternative launch options is driven by the growing interest in small satellites, for which the current Stratolaunch system is oversized. A smaller vehicle, he said, could be developed more quickly and less expensively. “It takes a more near-term focus on revenue generation,” he said.

Stratolaunch could eventually support several launch vehicles, he said, with varying payload capabilities to serve different customers. “We’ll likely have multiple launch vehicle options,” he said. “Some will be available earlier than others.”

It appears they are revising their launch system airplane into a modular design with a variety of upper stages, depending on customer. Note also the focus on the growing small satellite industry.

An engineering analysis of the Falcon 9 first stage landing failure

Link here.

SpaceX founder and chief technology officer Elon Musk tweeted that “excess lateral velocity caused it [the booster] to tip over post landing.” In a later tweet that was subsequently withdrawn, Musk then indicated that “the issue was stiction in the biprop throttle valve, resulting in control system phase lag.” In this statement, Musk was referring to “stiction” — or static friction — in the valve controlling the throttling of the engine. The friction appears to have momentarily slowed the response of the engine, causing the control system to command more of an extreme reaction from the propulsion system than was required. As a result, the control system entered a form of hysteresis, a condition in which the control response lags behind changes in the effect causing it.

Despite the failure of the latest attempt, SpaceX will be encouraged by the landing accuracy of the Falcon 9 and the bigger-picture success of its guidance, navigation and control (GNC) system in bringing the booster back to the drone ship. The GNC also worked as designed during the prior landing attempt in January, which ended in the destruction of the vehicle following a hard touchdown on the edge of the platform.

Why SpaceX’s first stage failure is really a magnificent success

Yesterday SpaceX attempted for the second time to land the first stage of its Falcon 9 rocket on an unmanned barge in the Atlantic. They failed, spectacularly.

I however consider this attempt to be a magnificent success. I also think they could fail at achieving this vertical landing for the next twenty launches and still those failures would each be a magnificent success.

Why? How can an engineering failure like this really be considered an achievement? It is very simple. Even if SpaceX continues to fail in its effort to recover its Falcon 9 first stage and reuse it, the possibility that they might succeed — demonstrated time after time by the company with each launch — has struck terror in the hearts of every other aerospace launch company. Each landing attempt shows SpaceX’s commitment to lowering launch costs while developing cutting edge engineering capabilities. Each attempt shows the world that they are the world’s leading launch company.

The result? Every other launch company in the world, both old and new, are scrambling desperately to lower their own costs as well as improve their own engineering.

Another successful Dragon/Falcon 9 launch

The competition heats up: SpaceX has successfully launched another Dragon freighter to ISS.

We await word on whether the first stage was able to successfully land vertically on a barge in the Atlantic.

Update: Musk reports that the first stage landed on the barge but “too hard for survival.” Expect some interesting video to follow. I have posted SpaceX’s video of the launch below the fold. Beginning at about 22:45, after first stage separation, you can see it maintain a vertical orientation as it begins its descent.

Stratolaunch update

This article about Paul Allen’s Stratolaunch company notes that the payload the system will put in orbit is likely to be less than originally hoped.

Still to be determined are the manned and cargo craft Stratolaunch will eventually send to orbit or even the International Space Station, Beames said. Musk’s SpaceX, an initial partner, is no longer associated with the venture. The rocket produced by Orbital ATK Inc., which replaced SpaceX, will probably be smaller than the medium-lift vehicle with a 6,000 kilogram (13,000-pound) payload that Stratolaunch had initially planned, Beames said. “I think it’s more likely we’ll be targeting a smaller payload class,” Beames said. “We’re not announcing anything on that yet.”

Allen’s company, Vulcan Aerospace, is also demanding that ULA change the name of its new Vulcan rocket, just revealed yesterday.

The skewed view of American inside the progressive bubble

Link here. The author captures well the cultural and intellectual chasm that exists between the modern American elite community, mostly leftwing, and the rest of American society. Sadly, that chasm is very clearly demonstrated by how most reporters are covering the emerging Presidential campaign. Read it and note the differences in how they approach both sides: They greet the Republicans with skepticism and scorn. They have private off-the-record dinners with Hillary Clinton.

90% of New Yorkers defy the state’s new gun registration law

Rebellion: A report in New York strongly suggests that more than 90% of the population is refusing to register their weapons as required by the new gun control law rammed through the legislature after the Sandy Hook massacre.

The article also notes that sheriffs and the rank-in-file have no intention of enforcing the registration part of the law either.

This story illustrates why it is essential we take great care in the laws we pass. If we write bad laws, we not only oppress innocent law-abiding citizens, we foster contempt for the law, which in the end can cause the collapse of civilized society and even more oppression.
