Shake-ups in the Google Lunar X-Prize competition

September 2, 2015 10:02 am Robert Zimmerman

One team has withdrawn and two big-name executives have left another team in a shake-up at the Google Lunar X-Prize competition.

This key quote however tells us the real state of the competition, which sadly does not look good:

The competition has repeatedly moved back the deadline to win the prize, which is now set for Dec. 31, 2017. At least one of the 16 remaining teams much announced a launch contract by the end of this year for the competition to continue. The rest of the teams would then have until the end of 2016 to announce launch contracts to stay in the race.

The team that withdrew says it plan to continue its effort but outside the competition. Either way, it looks like someone has to commit to a launch sometime in the next few months or the competition either has to push back its deadlines again or declare no winners. This will be a sad conclusion, as it is entirely possible for private financing to get this done. A failure however would make that appear impossible.

Technical problems for cosmic ray detector on ISS

September 2, 2015 9:53 am Robert Zimmerman

The failure of a second of four cooling pumps on the Alpha Magnetic Spectrometer on ISS threatens the science instrument’s ability to continue its observations.

The AMS continues to gather science data using the three remaining pumps. They are part of a liquid carbon dioxide cooling system that is meant to dissipate heat as the AMS, which is on the outside of the space station, cycles in and out of sunlight during each 90-minute orbit of Earth Only one pump is needed at any given time. One failed in February 2014 and at least one of the other three is showing possible signs of trouble.

Since the 8.5-tonne AMS began operating in 2011, it has tracked more than 69 billion cosmic rays flying through its detectors. Its goal is to search for antimatter and dark matter. In 2013, AMS scientists reported measuring numbers and energies of positrons that hinted at, but did not confirm, the existence of dark matter.

The news article suggests that the instrument is now working with only one reliable pump. It also is possible that repairs might be done by astronauts on ISS during a spacewalk.

Some background: AMS cost $2 billion and about 20 years to build. It only got launched because Congress ordered NASA to launch one more shuttle mission to ISS to get it there.

Atlas 5 successfully launches U.S. military satellite

September 2, 2015 9:45 am Robert Zimmerman

The competition heats up: ULA’s Atlas 5 rocket today successfully launched a U.S. Navy military communications satellite into orbit.

ULA’s big selling point for its very high prices is its very high reliability. This was its 99th consecutive launch success for the company, going back to 2006. It was also the 127th in a row for the Atlas 5.

The problem is that a majority of these launches were government payloads, which up until now has been willing to pay top dollar. For ULA to really compete successfully, it needs private customers, and they appear unwilling to pay that top dollar, going instead to SpaceX. It is for this reason the company is pushing hard to develop a more efficient and less costly rocket.

Manned Soyuz heads for ISS with new crew

September 2, 2015 9:38 am Robert Zimmerman

A new crew was successfully launched into orbit last night by a Russian Soyuz rocket.

This is the mission that Sarah Brightman was originally going to fly on as a tourist — before she backed out or was rejected by the Russians as a unqualified. Instead, it carries one Russian who is going to take over as commander of the station for a long term mission, and two short term astronauts, from Kazakhstan and Denmark, who will remain in orbit for only about 10 days.

They are taking the long, two-day rendezvous route to ISS, so they won’t actually dock until Friday.

Blue Origin wins financial incentives to build in Florida

September 2, 2015 9:31 am Robert Zimmerman

The competition heats up: Local county officials in Florida have awarded Blue Origins $8 million in grants to encourage it to set up launch operations in Florida.

The money comes from property tax revenue from new commercial and industrial construction in North Brevard, under a process the Brevard County Commission created in 2011 to help spur economic development in North Brevard. Blue Origin plans to build rockets on the Space Coast, and launch them from Cape Canaveral Air Force Station. The company, founded by Jeff Bezos, the billionaire chief executive officer of Amazon.com, would create 330 jobs with an average wage of $89,000, and plans to make a capital investment of $205 million to $220 million.

The company is being referred to as “Project Panther” in county documents, because Blue Origin has not officially disclosed its plans. Bezos is scheduled to be in Brevard County on Sept. 15 for a major announcement on the commercial space industry.

This news helps indicate what Bezos’s September 15 announcement will be about. They are likely to announce that the company is completed its arrangements for building its spaceport in Florida, and is now going to proceed. Up until now the company, which keeps its plans very close to its vest, has been vague about its future launch plans, especially after it lost its competition with SpaceX for leasing a launchpad at the Kennedy Space Center.

Blue Origin abandons patent for barge-landing a rocket

September 2, 2015 9:24 am Robert Zimmerman

The heat of competition: After losing a decision of the U.S. Patent office in a dispute with SpaceX, Blue Origin has withdrawn the patent it was awarded in March 2014 for vertical landing a rocket on an ocean-going barge.

In an order made public today, the U.S. Patent Trial and Appeal Board granted a motion to cancel the remaining 13 of 15 claims in the Blue Origin rocket-landing patent. Blue Origin itself had made the motion to cancel those claims, effectively acknowledging that its case was lost.

Blue Origin, based in Kent, Wash., has separately filed a “reissue” patent application covering the same general area. However, SpaceX has already attempted multiple rocket landings at sea and would likely be grandfathered in, allowing it to continue the practice, even if Blue Origin were to ultimately succeed in securing a valid patent.

The two companies are definitely in a heated competition. This is not the only legal dispute they have had, with SpaceX winning previously as well. Blue Origin had challenged the award of a 20-year lease to SpaceX of its launchpad at Kennedy. It lost.

In this case, it was absurd on its face for the patent office to award this patent to Blue Origin, especially since, at the time it did so, SpaceX was clearly already doing this exact thing.

Curiosity spots a spoon on Mars!

September 2, 2015 9:04 am Robert Zimmerman

The spoon on Mars

Very cool image time! In one of Curiosity’s recent images of the Martian surface on the slopes of Mount Sharp appears what looks like a long thin spoon jutting horizontally out of the ground.

The shadow below the feature is strong evidence that that this almost certainly a real object, shaped exactly as we see it. However, it is not an artificially created spoon. If you look at both the full raw image as well as zoom in on the feature itself, you will see that it is something that formed naturally due to Mars’ low gravity and the geology here. The spoon is a thin prong of harder material that has remained intact as the ground below it has been slowly eroded away by the ever-present but very weak Martian wind. If you look close you can see that harder material extend back into the rock behind the spoon.

Some of that erosion might also have been caused by flowing water sometime in the past, but to confirm this will take additional geological research.

Government still hasn’t notified individuals whose personal data was hacked

September 1, 2015 10:15 pm Robert Zimmerman

Government marches on! Months after the federal government admitted publicly that the personal data of more than 20 million government employees had been hacked they still have not sent notifications to those millions.

Instead, they’ve turned this into an opportunity to spend taxpayer money for their friends!

The agency whose data was hacked, the Office of Personnel Management (OPM), said the Defense Department will begin “later this month” to notify employees and contractors across the government that their personal information was accessed by hackers. OPM said notifications would continue over several weeks and “will be sent directly to impacted individuals.”

OPM also announced that it hired a contractor to help protect the identities and credit ratings of employees whose data was hacked. In a statement, OPM said it had awarded a contract initially worth more than $133 million to a company called Identity Theft Guard Solutions LLC, doing business as ID experts, for identity theft protections for the 21.5 million victims of the security data breach. The contractor will provide credit and identity monitoring services for three years, as well as identity theft insurance, to affected individuals and dependent children aged under 18, the agency said.

I wonder if Theft Guard Solutions donated campaign money to Obama in order to get the contract. I don’t know, but I wouldn’t be surprised. I also wonder if they are as incompetent at this work as the company the Obama administration hired to build the Obamacare website. I also don’t know this, but I also wouldn’t be surprised if they screw up just as badly.

An evening pause. Hat tip Phill Oltmann. I had sworn I had posted this already, but now can’t find it on BtB. And even if I have posted it, it is worth watching again. My only comment is that I am baffled by the film’s description of the event as “horrifying.” I don’t find this natural event horrifying, I find it awe-inspiring. It reminds us that the scale of the universe if far far beyond anything we can imagine.

Kentucky clerk again defies Supreme Court ruling on same-sex marriages

September 1, 2015 10:07 am Robert Zimmerman

A Kentucky county clerk continues to defy federal court rulings by refusing to issue any marriage licenses so as to avoid issuing same-sex licenses as well.

A Kentucky county clerk, defying a new U.S. Supreme Court decision and citing “God’s authority,” rejected requests for marriage licenses from same-sex couples on Tuesday in a deepening legal standoff now two months old. Citing her religious objections, Rowan County Clerk Kim Davis has refused to issue any marriage licenses since the Supreme Court in June ruled that same-sex couples had the right to marry under the U.S. Constitution.

On Monday the same court rejected Davis’ request for an emergency order allowing her to deny marriage licenses to same-sex couples while she appeals a federal judge’s order requiring her to issue them. Eight people filed a federal lawsuit against Davis in July challenging her office’s policy of not issuing marriage licenses to any couples – gay or straight.

I do not support any government official who arbitrarily decides to not follow the law. The issue here is whether the Supreme Court ruling itself followed the law. There are many legal experts who would say no.

Either way, this story illustrates the coming persecution of Christians and Jews whose faith tells them that any support of homosexual activities is wrong. You see, it is no longer acceptable to the homosexual community for these religious people to simply leave homosexuals alone and allow them to do what they want, as has been the case for the past half century. It is now demanded that the religious participate and endorse homosexual behavior, even if it goes against their own deeply held beliefs.

I want to point out again that no homosexuals have been prevented from living their lifestyle during this whole same-sex brouhaha. They remain free to live as they wish. The only people being persecuted are Christians, merely because they have refused to endorse that behavior. With these facts in mind, who do you think are the fascists?

With 8 days left in its campaign to raise $10 grand so that the Space Show can upgrade its website and make its archives searchable, the campaign is 70% funded.

As a regularly guest on David Livingston’s excellent show, I ask all my readers to consider donating to this campaign. For the past decade and a half The Space Show has probably provided the best and most complete coverage of the aerospace industry. The success of this campaign will allow the show to continue while also making the wealth of information buried in its archives more easily available to everyone.

Data from New Horizons does not match what is seen from Earth

September 1, 2015 9:10 am Robert Zimmerman

The uncertainty of science: Planetary geologists are presently baffled by a conflict in the atmospheric data between New Horizons and data gathered from Earth.

On 29 June, a few weeks before the fly-by, Young organized astronomers across New Zealand and Australia to watch Pluto as it passed in front of a distant star. Tracking how the star’s light faded during the passage provided information on how much gas is in Pluto’s atmosphere. Using the same method, planetary scientists have seen the atmosphere grow denser since 1988 — and analysis of the 29 June observations shows that the trend remains intact. Young calculates that the current atmospheric pressure at Pluto’s surface is 22 microbars (0.022 pascals), or 22-millionths the pressure at sea level on Earth.

But on 14 July, New Horizons measured Pluto’s surface pressure as much lower than that — just 5 microbars. “How we link the two, we’re still working on,” says Cathy Olkin, a deputy project scientist for New Horizons at SwRI.

The difference could simply be that Pluto’s atmosphere is not smooth, that some regions are dense while others are thin, and New Horizons happened to look at a thin place. The Earth observations don’t have the resolution to separate the two.

There are other proposals to explain the problem. Regardless, the answer is likely hidden in the data from New Horizons that has still not been downloaded back to Earth. In a few months, all might very well become clear.

Or not, as is the natural state of science.

What it was like practicing Islam for the first Malaysian in space

September 1, 2015 8:57 am Robert Zimmerman

This article, describing the 2007 flight of the first Malaysian in space, launched as a passenger in a Russian Soyuz capsule, is mostly worth reading because it goes into details on the Islamic religious rules the astronaut had to follow to practice the religion in space.

Muszaphar had to spend time going through an instruction manual on daily religious rituals provided by Malaysian mullahs. Vyacheslav Urlyapov of the Moscow-based Centre for Southeast Asia, Australia, and Oceania Studies, RAS Institute of Oriental Studies, sums up the cosmonaut’s experience: “The 11-day flight overlapped in part the holy month of Ramadan. Muslims had been in orbit before him, but it fell to Muszaphar to comply with the detailed instructions written for him by Islamic theologians (ulema) to remain a true believer in space, too.”

Muslims are required to face in the general direction of the city of Mecca while saying the mandatory – five times a day – prayers. But locating the tiny city from space is not an easy task, especially when you are hurtling around Earth at more than 17,000 km per hour. Also, in space there is no sense of direction – as we know it on land. The Malaysian cosmonaut was therefore all at sea during his first space flight.

Mercifully, Muszaphar was released from fasting, and was allowed to say shorter prayers and perform daily rituals according to Kazakhstan time. Plus, he didn’t have to face the constant ordeal of locating Mecca.

Kind of describes the problems when a medieval religion is thrust into the 21st century. The medieval religion has to change.

SpaceX delays its next launch

September 1, 2015 8:41 am Robert Zimmerman

SpaceX has decided to delay its next launch for several additional months as it continues its investigation into the June Falcon 9 launch failure.

The next mission on SpaceX’s launch calendar had been a U.S. government ocean-monitoring satellite called Jason 3, but Shotwell indicated that a commercial communications satellite would move to the front of the line. Luxembourg-based SES SA has a contract to fly on the first Falcon 9 rocket that features an upgraded first-stage engine. The upgrade will allow SpaceX to attempt to land its rockets back at the launch site from high-altitude missions so they can be refurbished and reused.

They had originally hoped to return to flight in September. This is now probably delayed until November. However, that their next flight will include the upgraded Merlin engine and it will be a commercial flight means they will once again likely try for a vertical landing of that first stage. Moreover, SES has already said that if the landing is successful it wants to buy that first stage for a future launch. SES hopes to save money this way, while also encouraging innovation in the launch market which it sees as a long term gain for putting its payloads into orbit.

Anti-establishment non-politicians top Iowa poll

August 31, 2015 9:11 am Robert Zimmerman

I normally don’t bother reporting on polls. They are notoriously unreliable and often force one to the wrong conclusions. Nonetheless, this poll appears significant because it indicates that it isn’t just Trump that the voters are turning to in their disgust of the establishment political elite community.

First, it is the first poll since late July that does not show Trump with a lead. Instead, Ben Carson ties him. Second, Carly Fiorina with 10% and Ted Cruz with 9% come in second and third.

Finally, and most important, Bush, Kasich, and Rubio, politicians who have demonstrated by their actions that once elected they cannot be trusted get little or no support.

For months I have strongly believed that Jeb Bush was going to go nowhere once the voting began. The Republican base does not want another Bush. Similarly, Rubio’s betrayal of the tea party voters who got him elected by his support of the Gang of Eight comprehensive immigration bill is well remembered by those tea party voters. They do not trust him.

Instead, I believe that it will be reliable conservatives or brash outsides like Cruz, Fiorina, Carson, and Trump who will get the votes. This poll suggests I might be right.

Having said this, I must emphasize again my mistrust of polls. It is just as likely this poll is a waste, and tells us nothing.

Obamacare to punish small businesses for helping employees

August 31, 2015 8:42 am Robert Zimmerman

Finding out what’s in it: The IRS has announced that the annual fine to businesses — even businesses with less than 50 employees — for helping employees pay their medical expenses will be a mere $36,500.

“We were told over and over during the Obamacare discussions that if you had less than 50 employees there’s no requirement to provide coverage, so you don’t have to worry about any cost factor,” said Ron Aldridge, Mississippi director for the National Federation of Independent Businesses. … If a company has five employees, the total tax would be $182,500. A “large” employer with 50 employees that did not provide insurance in compliance with the Affordable Care Act, would be subject to $2,000 per employee, with the first 30 employees exempt, for a total of $40,000, Aldridge said.

And then there’s this gem:

The Mississippi Insurance Department said: “The rule appears nowhere in the Affordable Care Act but was developed by the Obama administration’s regulation writers at the IRS.” [emphasis mine]

Not only is this IRS rule illegal, as it isn’t based on anything written in the Obamacare law, it starkly illustrates the inhumane attitude of the Obama administration and people there who wrote it. The rule demands that employers look the other way if their employees are in trouble because of medical expenses. It also surprises everyone by suddenly imposing Obamacare on all businesses, even tiny ones which had been promised they were exempt from the law.

In fact, based on the information in this article, even an independent contractor like myself could be found in violation of this rule and subject to fines.. Essentially, I am not allowed to use my profits from my business to pay for my medical costs,

In other words, this administration wants to hurt people.

That the police even considered arresting him was beyond reasonable. And three cheers for the player, Lane Pittman, for refusing to plea bargain.

Russia accelerating development of Soyuz replacement

August 30, 2015 8:52 am Robert Zimmerman

The competition heats up: The head of Energia, the Russian company that builds the Soyuz capsule, said this week at a space conference near Moscow that they are going to accelerate construction of a prototype of a next generation replacement, capable of launch four astronauts.

We have agreed with the engineers…. to reduce the time for construction and production of the first copy of this spaceship. Despite the fact that we have voiced and agreed on the first launch in 2021, we have set the task to build the prototype by 2019, and I think that we will succeed, ” Solntsev told reporters at the MAKS.

Take this with a grain of salt. Energia has proposed a number of different Soyuz replacements since 2000, none of which ever saw the light of day. At the same time, the situation in Russia has changed, and the government is now committed to financing a robust space program. Previously, Energia had to find private investment capital, which never arrived because, I think, investors did not trust the legal situation in Russia. They had no way of guaranteeing that they would own their shares. In fact, the recent take-over and consolidation of Russia’s entire aerospace industry by the government has proven those investor doubts entirely right.

At the same time, the increased competition in the launch industry and this government takeover might signal something real is finally going to happen.

New Horizons team picks its next Kuiper Belt target

August 28, 2015 3:07 pm Robert Zimmerman

The New Horizons science team has picked its next Kuiper Belt fly-by target beyond Pluto.

New Horizons will perform a series of four maneuvers in late October and early November to set its course toward 2014 MU69 – nicknamed “PT1” (for “Potential Target 1”) – which it expects to reach on January 1, 2019. Any delays from those dates would cost precious fuel and add mission risk. “2014 MU69 is a great choice because it is just the kind of ancient KBO, formed where it orbits now, that the Decadal Survey desired us to fly by,” said New Horizons Principal Investigator Alan Stern, of the Southwest Research Institute (SwRI) in Boulder, Colorado. “Moreover, this KBO costs less fuel to reach [than other candidate targets], leaving more fuel for the flyby, for ancillary science, and greater fuel reserves to protect against the unforeseen.”

The press release includes some silly gobbly-gook about how the science team can’t announce this as its official target because they still have to write up a proposal to submit to NASA, which then must ponder their decision and decree it valid. We all know this is ridiculous. Will NASA sit and ponder and make them miss their target? I doubt it.

The fly-by itself will be really exciting, because this object will truly be the most unusual we will have ever gotten a close look at, as it has spent its entire existence far out in the dim reaches of the solar system.

Judge rules IRS must disclose White House requests for private taxpayer information

August 28, 2015 1:13 pm Robert Zimmerman

The noose tightens: A federal judge today ruled that the IRS must turn over any records showing White House requests for private confidential taxpayer information.

Questions about potential White House meddling in taxpayers’ private information stretch back to the beginning of the Obama administration, when the then-White House chief economist seemed to describe the tax structure of Koch Industries during a briefing with reporters. His description was apparently incorrect, but it left some watchdog groups wondering if the White House had quietly sought information on conservatives, such as the billionaire Koch brothers.

Cause of Action sued in 2013 to get a look at whatever requests the White House, or other federal agencies, had made. The IRS refused, saying even the existence of those requests would be protected by confidentiality laws and couldn’t be released, so there was no reason to make the search. The judge said Friday, however, that the agency couldn’t use the privacy protection “to shield the very misconduct it was enacted to prohibit.”

If evidence is found that the White House was delving into the confidential tax records of its opponents, with IRS help, I think this scandal will finally reach critical mass. People might not go to jail, but the evidence will allow the individuals involved to sue and win in court. For the Democrats, Obama, and the IRS, this will not be pretty.

New EU tax law puts thousands out of business

August 28, 2015 11:42 am Robert Zimmerman

We’re here to help you! A major revision to the VAT tax in the European Union tax has caused the shutdown of thousands of businesses because they cannot afford to meet the complex rules and bureaucracy required.

Designed to prevent large businesses locating themselves in VAT-competitive territories, it had the predictable effect of drowning small businesses under a sea of bureaucracy, forcing them to access the data required to prove the customer’s location, figure out which of more than 80 VAT rates to apply, and issue an invoice in the correct language, currency and layout. Unable to afford the costly software required to deal with the regulation, thousands of small business and sole traders have closed or abandoned their enterprises. Most of those who have continued to trade have either moved to third party platforms, losing up to 70 percent of their total revenue (not just non-domestic sales) in commission, or spent thousands on software.

“The human cost to these businesses is vast”, Clare Josa is co-founder of EU VAT Action commented for EU Observer. “The only reason the Digital Single Market is still functioning is because awareness levels are below 5 percent, so most businesses are continuing to trade under the former system. As awareness rises, the damage will soar.”

Read the whole article. The quote above only gives a small taste of the problem caused entirely by government bureaucrats and elected officials who seem divorced from reality. And though this is a European governmental disaster, it is instructive for Americans to learn about it. Like Obamacare, the new VAT tax rules were imposed with the best of intentions, but completely ignored the reality of meeting those intentions. The result is financial ruin for thousands of businesses and individuals.

Hawaii Supreme Court hears arguments on TMT constructions

Hawaii’s Supreme Court on Thursday heard arguments for and against the construction of the Thirty Meter Telescope on the summit of Mauna Kea.

Based on reading the various news reports of the hearing and the questioning by the judges, it appears to me that the judges have already decided against the telescope. Race, ethnicity, and hatred of western technology must take precedent over all else.

I repeat: If the court shuts down TMT astronomers should consider moving out entirely. Furthermore, Americans should maybe consider other places for their tourism, considering how hostile Hawaiians now appear to be.

Comet 67P/C-G goes boom!

August 28, 2015 7:48 am Robert Zimmerman

Outburst on Comet 67P/C-G

Cool image time! On August 22, just days after its closest approach to the sun, Rosetta caught the outburst, image above, from the larger lobe on Comet 67P/C-G.

The image scale is 28.6 m/pixel and the image measures 29.3 km across. Although the activity is extraordinarily bright even in the original (below), the image above has been lightly enhanced to give a better view of the outline of the nucleus in the lower part of the image, as well as to show the full extent of the activity.

The most interesting images, I think, will actually come later, when the activity dies down and they can bring Rosetta in closer again. We will then be able to compare the nucleus both before and after this outburst, getting a sense of how the comet changes with each close pass to the sun.
