SpaceX offers 10% discount for satellites launched on reused 1st stages

10:46 pm

In interview today for Space News, SpaceX’s president Gwynne Shotwell revealed that the company is only offering a 10% launch discount for any satellite launch that uses a reused Falcon 9 first stage, not the 30% price break she had indicated in March.

Though the interview also touched upon SpaceX’s September 1 launchpad investigation, it did not include anything significantly new. Shotwell readily admitted that the company did consider sabotage as a possible cause, but always considered it unlikely and right now has pretty much dismissed it. She also remains confident that the company will resume launches this year.

Stratolaunch to use Orbital ATK’s Pegasus rocket

10:32 pm

The competition heats up? Vulcan Aerospace and Orbital ATK announced today that they are renewing their partnership, using Pegasus in conjunction with Stratolaunch to put satellites into orbit.

Under a multiyear “production-based partnership,” the companies said, Orbital ATK will provide “multiple” Pegasus XL air-launch rockets to be used with the Stratolaunch aircraft, which, when completed, will have the largest wingspan of any plane ever built.

With the Pegasus XL rockets, the Stratolaunch aircraft will be able to launch small satellites weighing up to 1,000 pounds, according to the firms’ joint statement released Thursday. Pegasus rockets already have done this kind of work: Orbital ATK has used them to launch satellites from the belly of its Stargazer aircraft.

This deal suggests to me that Vulcan Aerospace has a problem. It couldn’t find anyone to build a large rocket for Stratolaunch and this deal was therefore conjured up to paper over this problem. First , it appears that the reason Orbital ATK originally backed out was that they didn’t want to build the new rocket. Maybe they had engineering concerns. Maybe they were worried about cost or management. Regardless, they didn’t want to build it.

Second, using Stratolaunch with Pegasus seems pointless if the satellite weigh is still limited to only 1,000 pounds. That’s the payload capacity of Pegasus using Orbital ATK’s L-1011 Stargazer airplane. Why bother switching to Stratolaunch if the giant plane doesn’t give you any benefits?

Thus, it appears to me that what has happened is that Vulcan needed some rocket to use with Stratolaunch so that they could squelch the rising doubts about the company. This deal gives them that. It also probably gives Orbital ATK some extra cash to get them to agree to do it.

Predicting the next Martian global dust storm

5:22 pm

Scientists think they now have a method to predict the next global-wide dust storm on Mars, and based on this theory they predict it will happen very soon.

Global dust storms on Mars could soon become more predictable — which would be a boon for future astronauts there — if the next one follows a pattern suggested by those in the past. A published prediction, based on this pattern, points to Mars experiencing a global dust storm in the next few months. “Mars will reach the midpoint of its current dust storm season on October 29th of this year. Based on the historical pattern we found, we believe it is very likely that a global dust storm will begin within a few weeks or months of this date,” James Shirley, a planetary scientist at NASA’s Jet Propulsion Laboratory, Pasadena, California.

This is most interesting because my next rover update, later today or tomorrow, is going to note the increasingly dusty atmosphere in Gale Crater. It isn’t a global dust storm, but maybe it is indicative of one that is about to happen.

Success for New Shepard launch abort test

3:56 pm

The competition heats up: Blue Origin’s New Shepard capsule not only successfully rocketed away from its propulsion module and landed safely, the propulsion module unexpectedly survived today’ launch abort test and landed vertically as well.

This was the fifth flight of the propulsion module, which with the capsule will now be retired and placed on display.

Below the fold is the video of the entire test flight, including countdown and several long holds. The actual launch is at 1:06:19.

IRS renews harassment of tea party groups

9:23 pm

Still working for the Democratic Party: Despite repeatedly saying it has stopped its harassment of conservatives, the IRS this week issued a new set of invasive questions to one tea party group that has been waiting since 2012 for its non-profit application to be processed.

Worse, the IRS did it publicly, and in the process released confidential information.

More jarringly, the IRS then publicly released one of the sets of questions it sent to the Texas Patriots Tea Party — a move the group’s lawyer says puts secret taxpayer return information, supposed to be protected, out in the public. Tax experts say the IRS may be on safe legal ground, since the filing was made as part of a court case, and that’s one of the few narrow exceptions to strict IRSprivacy laws.

Still, the move to release the information has inflamed an already tense class action legal battle between the IRS and tea party groups who feel the agency is still targeting them more than three years after it promised to cease. “The IRS has taken the unprecedented step of publicly filing actual return information,” said Edward Greim, who is handling the case on behalf of more than 400 groups targeted by the IRS. He said the questions asked by the IRS show the agency has not ceased the intrusive questioning that landed it in trouble in the first place back in 2013.

This behavior tells us more about Barack Obama and the Democratic Party than the IRS itself. When the scandal initially broke, Obama expressed outrage and anger that such harassment was happening, but from the beginning has literally done nothing to end it. Instead, the IRS has stonewalled every investigation and court suit, including continuning its harassment of the President’s opponents. That could only be happening if the man running the executive branch, Obama himself, approved that behavior. In addition, the investigations have found that numerous Democratic members of Congress not only demanded this harassment, they continue to help the IRS in its stonewalling.

Expect worse should Hillary Clinton win the election. Her track record when she was first lady was actually worse than Obama’s.

Redesigned Antares launch scheduled for Oct 13

6:45 pm

NASA and Orbital ATK have now set October 13 as the date for the first Antares launch in two years.

Though ISS is not short of supplies, this quote underlines the difficulty of the particular situation now.

While the space station has plenty of food, water, experiments and other provisions, NASA officials are eager for the Antares rocket to resume flights as all of the research outpost’s other servicing vehicles are facing delays.

SpaceX’s Falcon 9 rocket, which launches the company’s Dragon cargo craft, is grounded after a launch pad explosion Sept. 1, and Dragon resupply missions to the space station may not start up again until early next year.

The Japanese HTV cargo freighter was supposed to blast off Sept. 30 with several tons of supplies, including new lithium-ion batteries for the space station’s electrical system. But that launch has been delayed until at least December after Japanese engineers discovered a leak during an air tightness test in August.

And a Soyuz crew capsule that was supposed to launch Sept. 23 with three new space station residents will not lift off until at least Oct. 19 after Russian workers discovered a technical problem on the vehicle. The Soyuz delay will likely push back the launch of Russia’s next unpiloted Progress cargo freighter from Oct. 20 until late November or early December.

Even with numerous redundent methods for hauling cargo to ISS, it is still possible for them all to have problems all at once.

Space letter wars in Congress!

6:34 pm

Turf war! A bi-partisan group of Congressmen, in response to an earlier letter by ten Republican senators questioning SpaceX’s ability to complete a thorough investigation of its September 1st launchpad explosion, have issued their own letter of support for the company.

In a letter to the heads of the Air Force, NASA and the Federal Aviation Administration, 24 members of Congress said that it was proper that SpaceX was leading the investigation. “Accidents are unfortunate events, and accident investigations should not be politicized,” wrote the bipartisan group led by Rep. Bill Flores (R-Tex.). “We encourage you to reject calls for your organizations to abandon established, well-considered and long-standing procedures.”

Ain’t democracy wonderful? It seems that SpaceX might have rounded up its own crony Congressmen to battle ULA’s crony Congressmen.

Vitas – Opera #2

6:02 pm

An evening pause: Hat tip Jim Mallamace, who also provides an English translation of the Russian lyrics, which I think combine very well with the dark and intriguing performance.

My house has been built,
But I’m alone in it.
A door was slammed behind my back.
Autumn wind is knocking at the window,
It’s crying over me again.
It was thunderstorm last night,
So it’s foggy in the morning.
The Sun got quite cold.
Old anguishes
Are going in a long train.
Let them get together.

My house has been built,
But I’m alone in it.
A door was slammed behind my back.
Autumn wind is knocking at the window,
It’s crying over me again.
It’s my fate, I can’t
Ask my fate for anything.
I only know, how the winds
Will cry after I’ve gone.

Agriculture Secretary demands Americans reduce their food portions

2:54 pm

We’re here to help you! The Obama administraton’s agriculture secretary on Monday called for Americans to stop wasting food by reducing their food portions.

Vilsack declared that “first and foremost, America can stop wasting food.”

“We can reduce portion sizes, we can have a more informed consuming public,” he said. “The USDA is providing an app that allows you to sort of go online and figure out if something’s been in the refrigerator for a couple of days, is it still OK to eat that type of thing? And if we can’t reduce it or reuse it, then we need to recycle it. So that’s one strategy that we’re working on.”

He was trying to outline ways to solve future food shortage issues as well as landfill shortages. However, this is really a case of the pot calling the kettle black. For example, I wonder if he has ever looked at the food that is routinely wasted at every Washington function at the fancy buffet tables that are made available to every participant. I doubt it. I suspect that food alone could probably feed the populations of several third world nations.

Morever, what business is it of his to tell us how much food we are allowed to eat? Since when did the federal government gain this power? Worse, I expect that every proposal that the government will try to solve the problem is only going to make it worse. Instead, the government should just shut up, get out of the way, and allow competition, freedom, and necessity to find solutions, quickly and in the most efficient manner.

The mystery of Tabby’s star deepens

7:07 am

Astronomers looking at the light variations of the star dubbed by some Tabby’s star have become even more baffled.

Spurred by a controversial claim that the star’s brightness gradually decreased by 14 percent from 1890 to 1989, Montet and Simon decided to investigate its behavior in a series of Kepler calibration images that had not previously been used for scientific measurements. “We thought that these data could confirm or refute the star’s long-term fading, and hopefully clarify what was causing the extraordinary dimming events observed in KIC 8462852,” explained Simon.

Simon and Montet found that, over the first three years of the Kepler mission, KIC 8462852 dimmed by almost 1 percent. Its brightness then dropped by an extraordinary 2 percent over just six months, remaining at about that level for the final six months of the mission. The pair then compared this with more than 500 similar stars observed by Kepler and found thata small fraction of them showed fading similar to that seen in KIC 8462852 over the first three years of Kepler images. However, none exhibited such a dramatic dimming in just six months, or a total change in brightness of 3 percent.

“The steady brightness change in KIC 8462852 is pretty astounding,” said Montet. “Our highly accurate measurements over four years demonstrate that the star really is getting fainter with time.  It is unprecedented for this type of star to slowly fade for years, and we don’t see anything else like it in the Kepler data.” 

At the moment, there is no good theory based on what astronomers know of stellar evolution to explain this star’s behavior. This does not mean the only explanation left is that aliens are building a Dyson sphere around the star, but it also leaves everyone at a loss to explain what is happening.

Not sabotage!

6:55 am

This closer look at the circumstances behind the September 1 Falcon 9 launchpad explosion outlines why sabotage by a sniper is almost certainly not the cause of the explosion.

The rocket was destroyed about eight minutes before it could start its engines for the static test fire. The supposed sniper could have waited until first-stage engine ignition, which would have covered the sound of a shot. Even a suppressed rifle can be quite loud, and the passage of the bullet through the air would have generated a distinctive sound. As Elon Musk wrote on Twitter a while ago, his team did not come to that conclusion. “Particularly trying to understand the quieter bang sound a few seconds before the fireball goes off,” Musk tweeted. “May come from rocket or something else.”

The .50-caliber Barrett rifle has a maximum effective range of little over a mile. It would be extraordinarily difficult (albeit not impossible) for a trained sniper to get within rifle range of the launch pad, given the tight security at Cape Canaveral Air Force Station.

The article also notes that fuel tanks simply don’lt explode when you fire a bullet into them. Moreover, the problem came from the rocket’s second stage helium tank, and it would have been easier for a sniper to fire at the rocket’s first stage.

It was necessary for the investigation to look into this possibility, but it is also necessary to put the suspicion aside when it is found to be invalid. SpaceX had a rocket failure of significant importance on September 1st, and they need to uncover its actual cause in order to prevent it from happening again. Getting distracted by theories that don’t work will prevent them from doing that.

Firefly shuts down

6:39 am

More details have been released by the shut down of operations at Firefly Space Systems.

They have furloughed all their employees, having lost one of their major investors. According to the company, the investor did not pull out because of the company’s litigation with Virgin Galactic, but because of its own internal considerations. The article also includes hints that Firefly might be one of the options that Vulcan Aerospace is looking at for building the rocket that its giant airplane Stratolaunch will launch.

Curiosity moves on

8:55 pm

The Curiosity science team today put out press release summarizing what they have accomplished at Murray Buttes and what they hope to do next.

For those who have been reading my weekly rover updates on Behind the Black, most of this release will be old news. However, the release did provide the following interesting geological information that supplements what I have been reporting:

This latest drill site — the 14th for Curiosity — is in a geological layer about 600 feet (180 meters) thick, called the Murray formation. Curiosity has climbed nearly half of this formation’s thickness so far and found it consists primarily of mudstone, formed from mud that accumulated at the bottom of ancient lakes. The findings indicate that the lake environment was enduring, not fleeting. For roughly the first half of the new two-year mission extension, the rover team anticipates investigating the upper half of the Murray formation. “We will see whether that record of lakes continues further,” Vasavada said. “The more vertical thickness we see, the longer the lakes were present, and the longer habitable conditions existed here. Did the ancient environment change over time? Will the type of evidence we’ve found so far transition to something else?”

The “Hematite Unit” and “Clay Unit” above the Murray formation were identified from Mars orbiter observations before Curiosity’s landing. Information about their composition, from the Compact Reconnaissance Imaging Spectrometer aboard NASA’s Mars Reconnaissance Orbiter, made them high priorities as destinations for the rover mission. Both hematite and clay typically form in wet environments.

It also appears that the problems they had while doing the last drill hole were related to the electrical design flaw of Curiosity’s drill. It caused a short circuit this time, which is worrisome based on what I understand because this design flaw has the capability of shorting out the rover’s entire electrical system, ending the mission.

I will post a new rover update later this week, once I get back from Illinois.

A detailed look at SpaceX’s Raptor engine

8:40 am

Link here. This story confirms for me a thought I had had while I watched Elon Musk’s talk last week outlining his proposed Interplanetary Transport System: SpaceX is still a good long way from actually building this rocket, since they have barely begun developing the rocket engine. They have made excellent progress in engine development, but they have a lot to do, with many pitfalls certain.

I therefore think that the company will be relying on its Falcon 9 and Falcon Heavy rockets, with their Merlin engines, for many more years to come.

Dark matter unnecessary?

9:06 pm

The uncertainty of science: A new analysis of the infrared data from 153 galaxies using the Spitzer Space Telescope suggests that dark matter might not be necessary to explain the rotation of galaxies.

First, this concise and nicely written explanation from the link of why dark matter has been proposed:

Newton’s laws of motion predict that planets that revolve closer to a star move faster than those that are farther away. In principle this should also hold true for stars circling the cores of galaxies, but for nearly a century, astronomers have seen that stars near the outskirts of galaxies orbit at nearly the same velocities as ones near galactic centers.

To explain why these outlying stars travel as quickly as they do without flying out into the void beyond, researchers came up with the idea of dark matter, a substance whose gravitational pull is thought to keep whirling stars in check. Scientists have largely ruled out all known particles as possible explanations for dark matter, and the consensus is that dark matter must be a kind of invisible, intangible material that is only detectable via its gravitational influence.

However, despite decades of trying, researchers have failed to capture a single mote of dark matter, even though it is supposed to make up roughly five-sixths of all matter in the universe. This raises the possibility that dark matter might not be real.

The new research, which I must admit I do not really understand, supposedly suggests that dark matter is unnecessary to explain the motions of stars.

Previous analyses of the orbital velocities of the stars in galaxies often depended on visible wavelengths of light. However, the stars that produce the most visible light are relatively short-lived and prone to fluctuations, and so may not provide the best picture of how matter is scattered overall throughout a galaxy. Instead, McGaugh and his colleagues analyzed near-infrared images collected by NASA’s Spitzer Space Telescope over the past five years. “The stars that generate the most near-infrared light are red giants, that are pretty stable in their output, and so are much better representative of a galaxy’s total mass of stars,” McGaugh said.

The researchers found an extraordinarily close association between the location of normal matter and the way it accelerates around the centers of galaxies. “We were surprised at how tight that relationship was,” McGaugh said. “It looks tantamount to a law of nature.”

Neither the article nor the scientists who did this research however explain clearly how this tight association negates the need for dark matter.

Sabotage?

9:08 am

The competition really heats up: The SpaceX investigation into the September 1 Falcon 9 launchpad explosion has apparently also included looking into the possibility that sabotage could have played a part.

As part of the investigation, SpaceX officials had come across something suspicious they wanted to check out, according to three industry officials with knowledge of the episode. SpaceX had still images from video that appeared to show an odd shadow, then a white spot on the roof of a nearby building belonging to ULA, a joint venture between Lockheed Martin and Boeing. The SpaceX representative explained to the ULA officials on site that it was trying to run down all possible leads in what was a cordial, not accusatory, encounter, according to the industry sources, who spoke on the condition of anonymity because of the ongoing investigation.

The building, which had been used to refurbish rocket motors known as the SMARF, is just more than a mile away from the launchpad and has a clear line of sight to it. A representative from ULA ultimately denied the SpaceX employee access to the roof and instead called Air Force investigators, who inspected the roof and didn’t find anything connecting it to the rocket explosion, the officials said.

To quote Sherlock Holmes, “When you have eliminated the impossible, whatever remains, however improbable, must be the truth.” In this case, it appears that they have eliminated this impossibility, though it is interesting that SpaceX felt compelled to consider it.

Cash shortage and court problems for Firefly

9:00 am

In the heat of competition: Firefly Space Systems appears to be in serious trouble with a court case going against it and what appears to be a loss of funding.

The legal battle took a turn in Virgin Galactic’s favor earlier this month when the arbitrator in the case (case no. 01-12-0002-2467) made a terminating sanctions ruling determining that Markusic did take Virgin Galactic trade secrets, destroyed evidence, impeded the arbitration process, and transferred Virgin Galactic confidential information to Firefly computers. This ruling makes any further legal action by Virgin Galactic much simpler as they no longer have to prove Markusic took their confidential information.

Things appeared to be going well at Firefly before this ruling, with a high volume of new hiring going on, a $5.5 million Venture class launch services contract with NASA, test firings of their engine, and a successful raise of $19 million in funding. Things may have changed with a statement posted to Twitter today on their @Firefly_Space account stating they have “experienced a setback on funding”.

Freedom and competition produces results fast and of high quality. It also carries risk and allows for failure. It appears that unfortunately Firefly might be illustrating the failure part of the equation.

Airbus signs first customer for its ISS external platform

7:35 pm

The competition heats up: Airbus has signed its first commercial customer for an external platform the company will be installing on ISS by the end of 2018.

Neumann Space is an Australian company developing a solar-electric thruster that uses metallic fuels rather than a gas like xenon. The company believes that the thruster will have a higher performance versus conventional electric thrusters and be able to use a wide range of metals as fuels. The company will install an experimental payload on Bartolomeo, a platform that Airbus plans to mount on the exterior of the Columbus module for experiments that require access to the space environment. Paddy Neumann, chief scientist and founder of Neumann Space, said the power requirements for the thruster made flying it on a cubesat or other small satellite impractical. “When we heard about the Bartolomeo platform, we leapt at the chance,” he said in a ceremony at Airbus’ booth at the IAC exhibit hall where the companies signed the agreement.

…Airbus announced the Bartolomeo platform in June as part of what the company called an “end-to-end service” to provide efficient commercial access to the ISS. The company hopes to have the platform installed on the Columbus module by the end of 2018, but officials at the conference said they were still working out launch arrangements and were in discussions with NASA for the spacewalk that will be needed to install the platform outside Columbus.

What is happening here with Airbus and ESA is the same thing that is happening at NASA: a transition from ownership by government to ownership by competing private companies. The positive ramifications of this transition cannot be measured, and have an almost limitless potential for accelerating the exploration of space.

Libertarian VP candidate praises Hillary Clinton

5:06 pm

No wonder all those mainstream newspapers are endorsing them: When asked if if Gary Johnson was more qualified to be president than Hillary Clinton, the Libertarian Party’s candidate for vice president, Bill Weld, expressed almost unqualified enthusiasm for Clinton.

When asked by NBC’s Chuck Todd if Johnson is more qualified for the presidency than Clinton, Weld responded that he is “not sure” if “anybody is more qualified” than Clinton for the position. Weld made the remark after expressing his displeasure with the idea of Donald Trump assuming the office.

It increasingly seems to me that Johnson and Weld’s sole purpose is to provide an option for those mainstream Republican RINO’s who hate Trump for irrational reasons and don’t want to vote for Hillary Clinton. The Libertarian candidates appear to give them a moderate choice (emphasis on the word moderate) that is also acceptable to the Washington crowd. I mean, really, how could anyone show up at a cocktail party in Silver Spring, Maryland after supporting Trump?

Black Lives Matter protesters shut down debate at university

8:53 am

Brownshirts: A mob of Black Lives Matter protesters shouted down a planned debate on the movement by the debate club of the University of Michigan, preventing it from happening.

Holding signs with statements such as “my life is not a debate” and “black lives are not up for debate,” as well as chanting “Black Lives Matter,” hundreds of protesters filed into the room where the Michigan Political Union, a non-partisan parliamentary forum that facilitates discussions about contemporary issues, was just beginning its debate Tuesday night.

Michigan Political Union’s President student Joshua Strup had attempted to hold the door into the venue closed as those at the debate heard the crowd of protestors approaching, as the room was already filled to capacity, but to no avail. The protesters burst through and stood along the room’s four walls as well as the walkways between chairs.

Comments and yelling ensued between the protesters and Strup, as well as student moderator Carlos Owens, both of whom attempted to quiet the crowd. But the protesters would not be silenced. They shouted out a series of chants after they entered the room, including “racists hurt race relations,” “black lives are not up for debate, and neither is mine,” and “if you are neutral in situations of injustice, you have chosen the side of the oppressor.” After their shouting spree, they laid on the ground to conduct a die-in demonstration. Thereafter, whenever a debate participant tried to speak, they would shout over them. Much of their comments were laced with profanity.

“You’re irrelevant [because] you’re white,” one protester shouted as student debater Jacob Roodvoets attempted to issue the speech he had prepared.

These bigoted fascists will not only not allow anyone to even discuss publicly the merits of their movement, they make it very clear that they are epitomize bigoted racism, ranking everything by race and preferring blacks over whites.

Office politics delays Russian ISS module

8:33 am

It appears that the reason work has stalled once again on Russia’s long delayed next module for ISS, the Multipurpose Laboratory Module (MLM), is literally because of office politics between government officials.

According to industry sources, the management at the military certification authority apparently ran into worsening relations with the leadership of the space industry.

In other words, there was some spat between the military guy and the space guy, and in revenge the military guy used his authority to stop all work.

Airbus imposes management cuts to save money

8:19 am

The competition heats up: In restructuring to cut costs and reduce its bureaucracy Airbus has decided to make significant management cuts and merge different divisions.

More here, including this revealing quote:

The move is the latest in [Airbus Chief Executive Tom] Enders’ four-year campaign to overhaul the company in the wake of the 2012 failed merger attempt with Europe’s largest arms maker BAE Systems PLC. “For me this is the logical conclusion of the journey we started in 2012,” Mr. Enders said.

After the deal faltered on German government opposition, he won shareholder backing for a new structure that reduced French, German and Spanish government involvement in company decision making, a legacy of the founding of the company in 2000 through the combination of European aerospace and defense assets.

The first link above also adds this:

[Airbus] changed its name from EADS and overhauled its governance in 2013-14, limiting the influence of French and German minority state shareholdings and granting more independence to management under German-born Chief Executive Tom Enders. But it remained saddled with separate bureaucracies and confusion over the brand, with the planemaking unit keeping the core “Airbus” identity and no fewer than five CEOs spread across the parent company, three units and one geographical division.

In other words, this restructuring is intended to remove any further government influence on the management of the company. Rather than provide pork for politicians, Airbus will now focus on maximizing its profits. The thinking here also corresponds with how the company organized its joint partnership with Safran and took over design and construction of Ariane 6 from the bureaucracy of the European Space Agency. Expect similar management cuts and even the possible elimination entirely of ESA’s Arianespace division in the coming years.
