New Shepard test flights to begin within weeks

8:21 am

The competition heats up: Blue Origin is expected to begin regular test flights of its suborbital resusable manned spacecraft, New Shepard, within mere weeks.

This news came from a government FAA official involved in approving flight permits. The company itself has declined to comment.

Even if it is a few months rather than weeks, these flight tests will put more pressure on Virgin Galactic in the race to become the first commercial suborbital tourism company to sell and actually fly a passenger. And if I had to bet who’d win the race, I would no longer put my money on Virgin Galactic.

NASA ISS cargo contracts delayed

8:15 am

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

9:40 pm

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

1:07 pm

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.

Rosetta records the appearance of a new jet on Comet 67P/C-G

9:21 am

jet appears on comet

Cool image time! Images taken two minutes apart by Rosetta have captured the emergence of a new jet on Comet 67P/C-G.

The two images released today show the remarkable onset of such a jet for the first time. They were taken on 12 March from a distance of 75 kilometres. In the first image, obtained at 07:13 CET, several rays of dust jets frame the upper, illuminated side of the comet. The dark underside shows no such features. Two minutes later, the picture has changed: a spectacular new jet has emerged on the dark side, hurtling dust into space and displaying a clearly discernable fine structure.

This was the first jet observed in a shadowed area, and the scientists think this jet might have started because it was just before dawn there.

More strikes at Vostochny

9:09 am

Another worker strike has broken out at the new Russian spaceport at Vostochny by workers who say they have not been paid their wages.

The strike itself is not the significant fact here. The significant fact is that even though the project has been under the close supervision of Putin himself since September, the wages were still not paid. Supervisors have been pocketing wages even as very high Russian officials have been publicly demanding that they get the construction back on schedule. And this story suggests that they continue to do so.

The entire situation implies a very extensive level of corruption at all levels of the Russian infrastructure, something that will make it very difficult for them to accomplish much in their future efforts in space.

Japan to the moon!

8:54 am

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.

TMT construction postponed again

7:49 am

The builders of the Thirty Meter Telescope have temporarily extended the suspension of construction originally demanded by Hawaii’s governor.

The tone of the article, especially the comments by the governor, suggests that the state is accepting the reality that they have no legal right to stop construction, and are making that fact very public. Instead, the govenor is now beginning the public relations campaign to make construction possible despite the protests, including negotiating some other givebacks to the protesters to shut them up. Sadly, those giveback appear to be the decommissioning of some other working telescopes as well as some increased restrictions on access to the mountain by the public.

Incorrectly built SLS welding machine to be rebuilt

9:16 am

You can’t make this stuff up. A giant welding machine, built for NASA’s multi-billion dollar Space Launch System (SLS), needs to be rebuilt because the contractor failed to reinforce the floor, as required, prior to construction.

Sweden’s ESAB Welding & Cutting, which has its North American headquarters in Florence, South Carolina, built the the roughly 50-meter tall Vertical Assembly Center as a subcontractor to SLS contractor Boeing at NASA’s Michoud Assembly Facility in New Orleans.

ESAB was supposed to reinforce Michoud’s floor before installing the welding tool, but did not, NASA SLS Program Manager Todd May told SpaceNews after an April 15 panel session during the 31st Space Symposium here. As a result, the enormous machine leaned ever so slightly, cocking the rails that guide massive rings used to lift parts of the 8.4-meter-diameter SLS stages The rings wound up 0.06 degrees out of alignment, which may not sound like much, “but when you’re talking about something that’s 217 feet [66.14 meters] tall, that adds up,” May said.

Asked why ESAB did not reinforce the foundation as it was supposed to, May said only it was a result of “a miscommunication between two [Boeing] subcontractors and ESAB.”

How everyone at NASA, Boeing, and ESAB could have forgotten to do the reinforcing, even though it was specified in the contract, baffles me. It also suggests that the quality control in the SLS rocket program has some serious problems.

Update: The original story at Space News that I originally linked to disappeared sometime in the next week, and was replaced with a slightly more detailed and more positive story, now linked above.

Sierra Nevada and Germany sign agreement

9:00 am

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.

Russia delays first manned launch from Vostochny

8:51 am

The Russian government has decided to delay from 2018 to 2020 the first manned launch from its new spaceport at Vostochny because an earlier launch would require them to use equipment they expect to retire anyway.

While the construction problems at Vostochny might be a factory in this decision, I also believe there is truth to the claim above. If they launch in 2018, they will probably have to use the Soyuz rocket to launch crews into space. By 2020 they plan to have Angara completely operational, and will be ready to retire Soyuz. Why build the infrastructure for Soyuz when you plan to retire it in only a couple of years anyway?

The delay however indicates a more fundamental problem with the Russian top-down authoritarian culture. It shouldn’t take them this long to get Angara operational. The rocket was conceived shortly after the fall of the Soviet Union in the early 1990s. They’ve had almost a quarter century to build it. Even though they’ve only just done the first two test flights, there is no justification for it to take another five years to get all the configurations of the rocket flying.

If they want to compete on the world market, they are going to have to work faster than this. A competitive private company, rather than delaying the launch, would have pushed Angara to be ready sooner so that the the launch could happen on time, with Angara. That the Russians seem unable to do this indicates that they will not be very competitive in the coming decades.

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

9:08 am

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

8:56 am

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

8:44 am

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.

No obvious evidence of advanced civilizations in 100,000 galaxies

10:57 pm

A search for evidence of advanced civilizations in the WISE orbiting telescope database has come up mostly empty.

Theoretical physicist Freeman Dyson proposed in the 1960s that advanced alien civilizations beyond Earth could be detected by the telltale evidence of their mid-infrared emissions. It was not until space-based telescopes like the WISE satellite that it became possible to make sensitive measurements of this radiation emitted by objects in space.

Roger Griffith, a postbaccalaureate researcher at Penn State and the lead author of the paper, scoured almost the entire catalog of the WISE satellite’s detections — nearly 100 million entries — for objects consistent with galaxies emitting too much mid-infrared radiation. He then individually examined and categorized around 100,000 of the most promising galaxy images. Wright reports, “We found about 50 galaxies that have unusually high levels of mid-infrared radiation. Our follow-up studies of those galaxies may reveal if the origin of their radiation results from natural astronomical processes, or if it could indicate the presence of a highly advanced civilization.”

Though the spin of the article is that no clear evidence of alien civilizations was found, I am most intrigued by those 50 candidate galaxies.

A real report of Hillary’s first campaign stop

11:37 am

Forget the press. Forget the spin. Read this report by an ordinary college student of her attempt to participate, as an “Everyday Iowan”, in Hillary Clinton’s first presidential campaign event. With great pictures.

My point here is not to lambast Clinton (of which this event is the least of her problems). My point is to lambast the press. This campaign stop was not much different than the campaign stops and photo events of all politicians, staged and managed and completely divorced from reality. Sadly the press goes along and reports the staging. This report, created by an amateur, instead gives us the reality of the event, something that the press should be doing.

Instead, our mainstream press plays along with the politicians. They should be ashamed.

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

9:48 am

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.
