UC-Berkeley and Google looking for amateur images of upcoming August eclipse

9:48 am

In the hope of producing a long movie of the August eclipse that will cross the entire continental United States, the University of California-Berkeley and Google have teamed up to put together a project that will gather images taken by amateurs.

The Eclipse Megamovie Project is seeking more than a thousand amateur astronomers and avid photographers to record the Aug. 21 total solar eclipse and upload their photos to be stitched together into a movie documenting the path of totality from landfall in Oregon until the moon’s shadow slips over the Atlantic Ocean off South Carolina.

While no one on the ground will see the total eclipse for more than 2 minutes and 40 seconds, depending on how close they are to the center of the path of totality, the images collected by the Megamovie’s volunteer team will be turned into a 90-minute eclipse movie unlike anything seen before. Even an airplane flying along the path of totality can only capture at most a four- to five-minute movie, since the moon’s shadow moves along the ground at up to 1,500 miles per hour. The last time anyone tried to stitch together eclipse images like this may have been in the 1800s via hand-drawn sketches, without the benefit of today’s modern digital technology.

While I think this is a great idea, I must state my reservations about UC-Berkeley. This university is hostile to free speech, and actually encourages violence against conservatives who either attend the university or come to speak there. To work with it on this project would be a kind of endorsement of that behavior.

ULA lets the press see part of SLS

9:38 am

Link here. The upper stage of SLS is undergoing its final testing in Michoud prior to shipment to Florida, and ULA had a press event to show it off.

“This is the first piece of integrated flight hardware for the SLS system to be shipped down to the Cape in preparation for our very first launch,” said Jerry Cook, Deputy SLS Program Manager for NASA. Cook noted that the ICPS test article is currently undergoing stress and load tests at Marshall.

The completion of the ICPS is yet another landmark in SLS’ development, though some contend it’s still a drawing-board vehicle. John Shannon, Boeing’s Vice President and General Manager of the SLS Program, disagrees. “The SLS has, in various forms, been called a paper rocket […] and, if I think you look to your right, you’ll see that absolutely is not true,” stated Shannon. “If you had the opportunity to go to the Michoud Assembly Facility in New Orleans, where we’re putting the bigger core stage together, you would also see that it is not true because we are putting hardware together as we speak.”

This upper stage engine is a brand new design and has never flown before, and the rocket it is part of has yet to be assembled. Yet NASA is considering flying humans on it during its first test flight, even as it harasses SpaceX and Boeing about using the Falcon 9 and Atlas 5 rockets, both proven repeatedly in operational flights, for their manned ISS missions.

The article also gives an update on the situation at Michoud since it was hit by a tornado on February 8. It appears that the facility is operating again, but not fully.

India’s space agency wants to build a space station

9:28 am

The decline begins: The head of India’s space agency ISRO yesterday advocated that his country build its own space station.

The spacesuit is ready. A survival capsule is on the way. ISRO has everything to send astronauts into space and develop a space station, all that’s left is for the government to give the money and policy clearance, said ISRO chief AS Kiran Kumar here on Monday. “We have the capability to create a space station, but you (government) have to give us the money and time to make this happen,” Kumar told reporters on the sidelines of 34th foundation day celebration of the Raja Ramanna Centre for Advanced Technology (RRCAT). “If the government and country decides… we are ready. You need to provide us funding, policy clearance,” he said, adding that space mission is low priority for the government “because one doesn’t see any immediate use of this in country’s development and growth”.

Kumar’s comments came in the backdrop of Chinese media reacting to ISRO’s recent record launch of 104 satellites at one go. An editorial in a Chinese newspaper pointed out that “there is no Indian astronaut in space and the country’s plan to establish a space station has not started”. [emphasis mine]

Rather than focus on development that could increase India’s competitiveness in the profitable launch market, such as improving its rockets either by making them reusable or able to launch more frequently, Kumar instead wants to spend his government’s money and build a space station. He doesn’t really outline what he intends to accomplish with this station, other than demonstrate that India can match China. His focus instead is creating an infrastructure for pork and jobs for ISRO. The station will not bring in profits, which would be more useful to the country and its nascent private space industry.

This is what government agencies routinely do. They might start out functioning like an innovative private company trying to attract customers, but the lure of coerced government money always takes precedence in the end, and the agency shifts its focus to building pork-laden empires funded by tax dollars.

Another nationwide wave of bomb theats against Jewish facilities

7:16 pm

For the fourth time in 2017 simultaneous bomb threats have been called against numerous Jewish community centers across the United States.

On Feb. 20, 11 Jewish community centers received called-in bomb threats, which were ultimately determined to be hoaxes. Our centers have in place security protocols to ensure the safety of their program participants and facility visitors. All JCCs have now received the all-clear from local law enforcement and resumed regular operations, with a heightened level of security…

The author of the article notes quite correctly,

The press release notes a total of 69 threats have been made against 54 Jewish centers in 27 states since the beginning of the year. I wrote about a previous wave of “telephone terrorism” in January. All of these incidents have turned out to be hoaxes but it’s important to note that many of the centers include schools with young children, leaving parents concerned about the safety of their kids.

Essentially, these bomb threats are hate crimes but because they are being committed against Jews our elite intellectual community has no outrage about them and does not care. In fact, if you speculate that these threats might be an effort of Islamic terrorists only then will that elite intellectual community be outraged, not at the terrorists but at you, for daring to express “Islamophobia.”

China suspends coal purchases from North Korea

3:49 pm

Finally! In an apparent response to North Korea’s recent ballistic missile test China has suspended its coal purchases from North Korea through the end of this year.

China will suspend all imports of coal from North Korea until the end of the year, the Commerce Ministry announced Saturday, in a surprise move that would cut off a major financial lifeline for Pyongyang and significantly enhance the effectiveness of U.N. sanctions. Coal is North Korea’s largest export item, and also China’s greatest point of leverage over the regime.

The ministry said the ban would come into force Sunday and be effective until Dec. 31. China said the move was designed to implement November’s United Nations Security Council resolution that tightened sanctions against the regime in the wake of its last nuclear test.

While there are doubts this will change policy in North Korea, it does indicate that China is finally losing patience with that rogue state and its threatening behavior. And since China is one of the few countries that does any trade with North Korea, it is probably one of the few countries that can influence it in any way.

SpaceX delays first Dragon Mars mission to 2020

3:31 pm

SpaceX has decided to delay its first Dragon flight to Mars from 2018 to 2020 so as to focus on more immediate priorities.

Instead of aiming for the 2018 deadline, SpaceX will now try to launch a robotic mission to Mars — known as its Red Dragon mission — two years later, in 2020, SpaceX president Gwynne Shotwell said during a press conference Friday.

This delay will allow the company to refocus on other more, earthly ambitions in the near term before setting its sights on Mars down the road. “We were focused on 2018, but we felt like we needed to put more resources and focus more heavily on our crew program and our Falcon Heavy program, so we’re looking more in the 2020 time frame for that,” Shotwell said.

They need to fly the Falcon Heavy several times first, and the delays caused by last year’s September 1 launchpad explosion, has pushed the first Falcon Heavy launch back from late in 2016 to the summer of 2017.

Juno to remain in 53-day orbit

1:47 pm

The scientists and engineers running the Juno mission to Jupiter have decided to keep the spacecraft in its 53-day orbit for the rest of its mission rather than fire its engines to lower the orbit to its planned 14 days duration.

The original Juno flight plan envisioned the spacecraft looping around Jupiter twice in 53-day orbits, then reducing its orbital period to 14 days for the remainder of the mission. However, two helium check valves that are part of the plumbing for the spacecraft’s main engine did not operate as expected when the propulsion system was pressurized in October. Telemetry from the spacecraft indicated that it took several minutes for the valves to open, while it took only a few seconds during past main engine firings. “During a thorough review, we looked at multiple scenarios that would place Juno in a shorter-period orbit, but there was concern that another main engine burn could result in a less-than-desirable orbit,” said Rick Nybakken, Juno project manager at NASA’s Jet Propulsion Laboratory in Pasadena, California. “The bottom line is a burn represented a risk to completion of Juno’s science objectives.”

There are both pros and cons for using this longer orbit, detailed at the link, with.the most important being that doing nothing avoids losing the mission entirely.

Tilleson starts State Department purge

11:35 am

Cleaning house: The Trump administration carried out major lay-offs in the staffing at high levels of the State Department on Thursday.

Much of seventh-floor staff, who work for the Deputy Secretary of State for Management and Resources and the Counselor offices, were told today that their services were no longer needed. These staffers in particular are often the conduit between the secretary’s office to the country bureaus, where the regional expertise is centered. Inside the State Department, some officials fear that this is a politically-minded purge that cuts out much-needed expertise from the policy-making, rather than simply reorganizing the bureaucracy.

In addition, it appears that the new Secretary of State Rex Tillerson is also pulling the fangs from many other State Department managers, many of whom have indicated a partisan hostility to the Trump administration.

There are clear signals being sent that many key foreign policy portfolios will be controlled directly by the White House, rather than through the professional diplomats. Not a single State Department official was included in the White House meetings with Israeli Prime Minister Benjamin Netanyahu this week.

Good. It is important that federal employees of all stripes learn that a new administration has been elected by the American people, and it is there job to do what that administration wants, not what they want.

Dawn finds organics on Ceres

9:34 pm

The spacecraft Dawn has detected evidence of organic molecules in Ceres’ northern hemisphere.

The organic materials on Ceres are mainly located in an area covering approximately 400 square miles (about 1,000 square kilometers). The signature of organics is very clear on the floor of Ernutet Crater, on its southern rim and in an area just outside the crater to the southwest. Another large area with well-defined signatures is found across the northwest part of the crater rim and ejecta. There are other smaller organic-rich areas several miles (kilometers) west and east of the crater. Organics also were found in a very small area in Inamahari Crater, about 250 miles (400 kilometers) away from Ernutet.

This detection does not mean that Dawn has found life on Ceres. It means that the spacecraft has detected molecules that contain carbon, which is the chemical definition of organics. Nor is it unusual for asteroids to have carbon molecules. In fact, there is an entire asteroid class dubbed carbonaceous chondrites that are rich in carbon. In addition, the press release overplays this narrative by making it seem as if the discovery of organics in the solar system is rare and unusual. It is not. Molecules containing carbon have been found in many places, on Mars, on Venus, in asteroids, and elsewhere. All that is happened here is that the scientists have gained more information about the make-up Ceres itself. This is good, but it isn’t what is being sold by the press release.

UAE proposes building Martian city within a century

12:13 pm

The competition heats up? The United Arab Emirates announced on Tuesday its plan to construct a city on Mars and have it completed by 2117, a hundred years from now.

On Tuesday, at the sidelines of the World Government Summit in Dubai, the UAE announced that it was planning to build the first city on Mars by 2117. According to CNBC, UAE engineers presented a concept city at the event about the size of Chicago for guests to explore.

In a statement, Sheikh Mohammed bin Rashid Al Maktoum, ruler of Dubai and vice president of the UAE, sounded confident about the project. “Human ambitions have no limits, and whoever looks into the scientific breakthroughs in the current century believes that human abilities can realize the most important human dream,” Maktoum said.

And despite the grandiose nature of the idea, the 100-year-plan does emphasize some practical steps. “The Mars 2117 Project is a long-term project,” Maktoum explained in the statement, adding that the first order of business would be making space travel appeal to young Emiratis, with special programs in space sciences being set up at universities in the UAE.

Maktoum is the guy that pushed to create the UAE’s space agency, and is leading its effort to fly an unmanned mission to Mars by 2020. It is very clear that his goal is to inspire his country and its youth so that they will aim high in future years. I wish him well, as this is a far better goal for an Islamic nation than sending out suicide bombers to kill innocent people.

I must add that I remain very skeptical about this particular plan. I fully expect us to finally get to Mars in the next century, but whether we will have the ability to build cities there in that time frame remains questionable.

Republican leaders propose Obamacare revisions

11:31 am

Cowards: The House Republican leadership today put forth a series of proposals for revising — not repealing — Obamacare.

A packet distributed to lawmakers at the meeting and obtained by The Hill says the GOP bill will include tax credits, an expansion of health savings accounts, money for high risk pools to care for the sick and a major restructuring of Medicaid to cap federal payments.

No dollar figures for any of the Republican proposals have been presented yet. Lawmakers said that is because the Congressional Budget Office is still analyzing the plan.

Nowhere do these proposals deal with repealing Obamacare’s ban on low-cost catastrophic health insurance plans. In fact, these proposal do little to repeal any of Obamacare’s worst regulations, which make the entire concept of health insurance unsustainable. Instead, these proposals nibble at the edges of the law, and will only serve to make things worse. For example, the proposals will repeal all the taxes that pay for Obamacare’s costs, will eliminate the mandates that force people to buy insurance, but will do nothing to relieve insurance companies from the law’s requirements, such as forcing them to accept every applicant, no matter how sick. Such a crazy arrangement will guarantee that no one will buy health insurance until they need it, making it entirely unprofitable.

The whole mess is simply too complicated. The time has come to do what Alexander the Great did: rather than try to untie the Gordian knot, he simply took a sword and cut it. Congress should do the same to Obamacare. Only then will the health insurance industry have a chance of recovery.

Two congressmen propose naming SLS for astronaut Gene Cernan

9:43 am

Two congressman yesterday introduced legislation that would rename SLS after Eugene Cernan, the last Apollo astronaut to walk on the Moon.

I don’t think anyone would argue with this. First, SLS is a terrible name for the rocket. Second, Cernan deserves the recognition.

At the same time, I suspect this is happening as part of an overall push within the Washington community to sell SLS to Trump and his administration. This proposal, as well as the recent news stories proposing SLS/Orion Moon missions and putting astronauts on SLS’s first flight, all point to a lobbying effort inside NASA, Congress, and the big space community to save SLS, which when compared to the successes and achievements of commercial space since 2010 appears an abject failure.

That comparison is at the heart of my policy paper, Capitalism in Space, which will hit the newstands next week. It makes it very clear how much a failure SLS/Orion has been, and how embarrassing that failure stands when compared to commercial space.

Rocket Lab delivers first test rocket to launch site

9:31 am

The competition heats up: Rocket Lab has delivered its first test rocket to its New Zealand launch complex in preparation for testing.

Over the coming weeks, a series of tests and checkouts will be conducted at the site before the rocket, named “It’s a Test,” is signed-off to fly. “We put it out to our team to name the vehicle,” said Beck. “We wanted to acknowledge the intensive research and development Electron has undergone and that continues with these test flights.”

The launch, which will be the first orbital launch attempt from New Zealand, is the first of three planned tests before Rocket Lab begins providing customers commercial satellite launches.

They hope to launch their first commercial payload on an operational Electron rocket before the end of this year.

India preparing rover for 2018 Moon landing

9:18 am

The competition heats up: India preparing rover for 2018 Moon landing.

Isro’s Satellite Applications Centre Director, M. Annadurai, revealed the tentative launch schedule while speaking to the press at the Satish Dhawan Space Centre, Shar, Sriharikota on Wednesday. He said a Lander and a six-wheeled Rover were being prepped to go with the Chandrayaan-II mission. The chief scientist added that a launch is likely to take place in the first quarter of 2018. According to Dr P.V. Venkita Krishnan, the director of the Isro Propulsion Complex at Mahendragiri, engineers were currently testing soft-landing engines.

India’s launch of a record 104 satellites on a single rocket has pumped up the Indian press, as there were almost 20 stories on space and that launch in their press today, almost all favorable.

This article however is from the U.S., and takes a look at the ineffective American space policy that supposedly forbids American companies from launching on Indian rockets.

The U.S. Commercial Space Launch Agreement of 2005 prohibits the launch of commercial satellites on the Indian vehicle. The reasoning is that struggling U.S. commercial launch providers needed time to establish themselves in the market and would be wiped out by India’s PSLV, which is developed by the Indian Space Organization.

Since 2015, commercial satellite owners have successfully obtained waivers to the policy.

The article notes India’s competitive prices, as well as the overall state of the smallsat industry and its dependence on bigger rockets as secondary payloads to get into space. India’s rockets, funded and subsidized by the government but also built to be inexpensive so as to attract customers, is clearly positioned to effectively compete with SpaceX, who until now charged the least.

What will our Congress do? My preference would be for them to repeal this part of the 2005 law so that American satellite companies can fly on whoever they wish. That would increase competition but it would also likely invigorate the overall launch industry because it would increase the satellite customer base for those rockets and thus create more business for everyone.

Sadly, I suspect that Congress will instead demand that the waivers to the law cease, and will thus block the use if Indian satellites by American companies. The short-sightedness of our politicians never ceases to surprise me.

NASA considers putting astronauts on first SLS/Orion flight

1:28 pm

Faced with indications that Trump wants a manned lunar mission during his first term, NASA’s acting administrator has asked his engineers and management to look into the possibility of putting humans on the first SLS/Orion launch, now set for late in 2018.

As the Acting Administrator, my perspective is that we are on the verge of even greater discoveries. President Trump said in his inaugural address that we will “unlock the mysteries of space.” Accordingly, it is imperative to the mission of this agency that we are successful in safely and effectively executing both the SLS and Orion programs.

Related to that, I have asked Bill Gerstenmaier to initiate a study to assess the feasibility of adding a crew to Exploration Mission-1, the first integrated flight of SLS and Orion. I know the challenges associated with such a proposition, like reviewing the technical feasibility, additional resources needed, and clearly the extra work would require a different launch date. That said, I also want to hear about the opportunities it could present to accelerate the effort of the first crewed flight and what it would take to accomplish that first step of pushing humans farther into space. The SLS and ORION missions, coupled with those promised from record levels of private investment in space, will help put NASA and America in a position to unlock those mysteries and to ensure this nation’s world pre-eminence in exploring the cosmos.

This is incredibly stupid. That first flight will be the very first time SLS will fly. It will also be flying with an upper stage engine that has also never flown before. It will take the Orion capsule to the Moon, when the capsule itself has not yet even done one orbit around the Earth. To put people on it makes no engineering sense at all.

Freedom Caucus to push for swift Obamacare repeal

3:44 pm

In a direct clash with the Republican leadership that increasingly wants to slow down a repeal of Obamacare, the conservative House tea party group dubbed the Freedom Caucus announced today that they will push for an immediate repeal of the law.

The House Republican leadership is made up of a bunch of cowards. They fear the polls. They fear the press. They fear the astroturf demonstrations paid for by the left. They fear everything. And they believe in nothing, because if they did believe in freedom and restricting the power of government they would move quickly to repeal Obamacare and let the chips of freedom fall where they may.

Maybe the Earth’s magnetic field is not weakening

3:31 pm

The uncertainty of science: New data using date-stamped jars covering the period from the 8th to the 2nd century BC suggest that the 8th century BC was a period when the Earth’s magnetic field was particularly strong, leading the scientists doing the research to conclude that the Earth’s magnetic field might not be weakening and that the recent field strength decline detected in the past two hundred years might simply be part of the field’s normal fluctuations.

This new data is certainly worthwhile, but the press release surely doesn’t reveal how the scientists were able to extrapolate future magnetic field strength from 8th century BC fluctuations. At a minimum, I would need to see a graph showing the measured field strength from the 8th century BC to the present time to see how today’s field strength compares with the past. Unfortunately, the press release does not provide this.

The international government effort to come up with a cis-lunar ISS

10:12 am

The competition heats up: In the past five years the various international partners and their space agencies have been conducting studies for developing a new international space station, this time based not in Earth orbit but located near the Moon.

Following initial approval in the fall of 2014, the five space agencies formed the ISS Exploration Capabilities Study Team, IECST, which was tasked with reviewing how the ISS experience could be used to build the cis-lunar infrastructure, with determining its possible architecture and with drafting its flight plan and possible mission. Specialists also had the task of looking at all the necessary technologies, logistics and maintenance which would be required for building and operating a small habitat near the Moon. This man-tended outpost could serve as a way station to the lunar surface and as a springboard for the exploration of the Solar System, including asteroids, Mars and its moons. In fact, the outpost itself could eventually embark on a journey toward a deep-space destination. Representatives of the various space agencies also tried to see what contributions each country could make, based on their technical capabilities and realistic budgets.

All the work was conducted within the ISS program and covered by its budget.

Initially, the IECST group included representatives from space agencies only, for the exception of Russia, with Roskosmos officials needed help from the nation’s prime contractor in human space flight — RKK Energia. For the final few meetings in 2016, ESA also brought representatives from the European space industry. However NASA did not directly involve its key human space flight contractors into the IECST activities. (Instead, the US aerospace companies Boeing and Lockheed Martin continued parallel studies in cooperation with RKK Energia in Russia, EADS Astrium in Europe and Mitsubishi in Japan.) [emphasis mine]

Read the whole article. Lots of interesting details.

In a sense, this international effort is a political lobbying effort by these space agencies to come up with a single project to follow ISS that will continue the funneling of government money to them all. It is also an effort by them to structure future space exploration so all efforts will be contained within this single program, rather than allowing for many different competing efforts, both private and public. In addition, it is an attempt by NASA to come up with some long-term mission for SLS/Orion, which at present has no operational purpose and no funding beyond its first manned flight in 2021.

Finally, note the highlighted sentence above. This effort — which will benefit not just NASA but the space agencies of Russia, Europe, and Japan as well as the old big space companies like Boeing, Lockheed Martin, and Mitsubishi — is been paid entirely by American tax dollars. Something about this to me seems wrong. Shouldn’t the cost here be shared? And doesn’t it seem inappropriate for NASA to be picking the companies it wants to work with, without open bidding?

Short circuit caused launch failure of Japanese mini-rocket

9:53 am

Japanese engineers now believe that the cause of the failure of that country’s test launch of a mini-rocket on January 15 was because of the failure of wiring insulation.

The agency said it believes the cladding of electric cables was damaged by the vibration and heat of nearby metal parts, leading the cables to directly touch the metal parts. As a result, a short circuit occurred and a data transmission device lost power, it said.

It is remarkable how much the language of this story reminds me of Soviet era press releases. Everything about it is designed to obscure the problem so that it will be difficult for outsiders to understand what happened.

From what I gather, the cables were not properly secured so that during launch they rubbed violently against some nearby sharp metal parts, which then cut the insulation and caused the short circuit. That they were not properly secured, a basic engineering requirement for any rocket, and that this announcement is written to obscure this fact, suggests once again that Japan’s space agency has some serious quality control problems that it is still not facing.

Countdown begins on India’s record-setting launch of 104 satellites

9:41 am

The competition heats up: ISRO has begun the countdown for Wednesday’s launch of India’s PSLV rocket, carrying a record-setting 104 satellites.

he Polar Satellite Launch Vehicle would be carrying a 714 kilogram main satellite for earth observation and 103 smaller “nano satellites” which would weigh a combined 664 kilograms. Nearly all of the nano satellites are from other countries, including Israel, Kazakhstan, The Netherlands, Switzerland, United Arab Emirates and 96 from United States, said the state-run ISRO.

If successful, India will set a world record as the first country to launch the most satellites in one go, surpassing Russia which launched 39 satellites in a single mission in June 2014.

Obviously, all these different satellites got a cut-rate launch deal by sharing the launch, which helps make their launch affordable. The disadvantage here is that they do not have much flexibility in choosing their orbits, which is why there is also a market now for small rockets aimed at launching single smallsats, such as Rocket Lab’s Electron.

A comet breaks apart

9:27 am

On February 12 members of the amateur astronomy organization Slooh actually viewed the break-up of Comet 73P/Schwassmann-Wachmann into two large fragments.

On the night of February 12th, Slooh members using the company’s telescopes in Chile were able to view the comet as it broke into two pieces. This seems to be the continuation of a process that was first witnessed in 1995, then again in 2006.

Slooh members were among the first to confirm that the nucleus of comet 73P/Schwassmann-Wachmann had split into at least two large pieces. “They immediately pointed Slooh’s telescopes to capture the event,” says Slooh Astronomer, Paul Cox. “Members will continue to monitor the comet live over the coming weeks – assuming the comet survives that long.”

They have created an animation from their images, but it appears that they only started taking images after the actual breakup, so the animation shows the two fragments, but not the moment they broke apart.

X-37B about to land?

9:20 am

Because of sudden Air Force preparations of the old space shuttle runway at Cape Canaveral it is now believed that the X-37B spacecraft presently in orbit for the past 21 months is about to come home.

The spacecraft has not yet landed, but recent orbital changes spotted by amateurs as well as runway preparations at the Cape all point to an end to the mission.

In preparation for landing at Kennedy, teams practiced landing drills and post-landing safing operations as well as emergency drills at the SLF [Shuttle Landing Facility] last week.

The X-37B landing also helps explain the until now curious delay to SpaceX’s launch of the SpX-10 resupply mission for the International Space Station which had originally been scheduled for the 14th as well – the opening day of the X-37B’s landing attempts at Kennedy. When the SpaceX mission was delayed, it was stated that range assets necessary for the return to launch site landing of the Falcon 9 core stage were not available from 14-17 February, while all other range assets necessary for launch were available during that window.

While the secretive nature of the mission precludes any exact knowledge of the ground track the X-37B will take, a descending node reentry over large portions of the United States is the likely option given the landing window for the restricted air space in and around the Kennedy Space Center.

If the X-37B lands this week, it will have completed the fourth such mission from the Air Force’s known fleet of two spacecraft. One did flights 1 and 3, while the other did flights 2 and 4.

Heart risks from secondhand smoke completely bogus

7:09 pm

The uncertainty of science: New more carefully done research now proves that secondhand smoke from smoking does almost nothing to increase the risk of heart disease.

In the early 2000s, as jurisdictions across the country fought over expanding smoking bans to bars and restaurants, anti-smoking advocates seized on the Helena study and related research showing that secondhand smoke exposure can affect coronary functions to promote fear of secondhand smoke. Groups across the country stated that “even half an hour of secondhand smoke exposure causes heart damage similar to that of habitual smokers.” Not to be outdone, the Association for Nonsmokers in Minnesota wrote in a press release that just 30 seconds of exposure could “make coronary artery function of non-smokers indistinguishable from smokers.” The message to nonsmokers was clear: The briefest exposure to secondhand smoke can kill you.

A decade later, comprehensive smoking bans have proliferated globally. And now that the evidence has had time to accumulate, it’s also become clear that the extravagant promises made by anti-smoking groups—that implementing bans would bring about extraordinary improvements in cardiac health—never materialized. Newer, better studies with much larger sample sizes have found little to no correlation between smoking bans and short-term incidence of heart attacks, and certainly nothing remotely close to the 60 percent reduction that was claimed in Helena. The updated science debunks the alarmist fantasies that were used to sell smoking bans to the public, allowing for a more sober analysis suggesting that current restrictions on smoking are extreme from a risk-reduction standpoint.

As almost always happens, the people pushing for the ban really weren’t that interested in protecting people’s health. They might have thought so, but in reality what they were really interested in was exerting their power over others, banning smoking and telling everyone else how to live their lives.

Read the whole article. It is very damning, and illustrates again why it is very important to not pass laws quickly based on some preliminary scientific results. Care must be taken, and patience is required. The science is never clear right from the beginning, especially on complex issues like climate and the health effects involving large numbers of people.
