Falcon 9 launches NASA satellite, first stage landing fails

7:30 pm

The competition heats up: SpaceX successfully put its first NASA/NOAA science satellite in orbit today, though its attempt to land the Falcon 9 first stage on a barge failed when one landing leg broke and the stage tipped over.

The first stage however was still recovered as it fell sideways on the barge. The link above includes a picture, which shows that stage lying on its side. The engines might be recoverable, but certainly they have enough material from the stage to do tests and learn a great deal more about how it tolerates the stresses of launch. Commenter Frank provides a link to a video that shows the stage falling over and exploding, something the images I had seen previously had not shown. They might have more material to test, but hardly as intact as I had first thought.

Nonetheless, they have now successfully test fired the engines from last month’s recovered first stage.

The 156-foot first stage booster that carried out that successful landing was taken to the company’s hangar at Launch Complex 39A at NASA’s Kennedy Space Center in Florida and partially inspected. It was later taken back to Launch Complex 40 and hoisted upright via a crane. On Jan. 15, a static fire was conducted. “Data looks good overall,” Musk said in a tweet, but noted Engine No. 9—one of the outer engines—showed thrust fluctuations. He said that there may have been some debris ingestion, but the engine data looks OK and that they would borescope later that night. There has been no word on how that inspection went.

That all nine engines functioned is a very good sign, even if one had issues.

A river on Mars

11:02 am

A river on Mars

Cool image time! The science team for the high resolution camera on Mars Reconnaissance Orbiter this week released it monthly set of cool images. One of those images, which I have cropped and reduced to show it here, is of an ancient river on Mars, the formation process of which geologists still debate. As the scientists note,

The channel pattern, called “dendritic” because of its tree–like branching, begins at the top of the image and runs down over the rim of an ancient impact basin across the basin floor. The soil surface overlying these channels, and indeed the entire landscape, has been changed and reworked over the intervening millions of years, by the combined actions of wind and ice. Over time, the original channels become muted or even erased.

One thing I learned in writing an article for Astronomy about the rivers seen on Saturn’s moon Titan is that without plant life there is no known natural process to hold river banks in place. Instead, if the grade is shallow and not confined by bedrock cliffs, rivers will meander about randomly forming braided channels as there will be nothing on shore to hold the water within the same course. For example, on a lifeless Earth the water draining the central basin of the midwest United States would have flowed south across a wide scattered area covering the entire plains, rather than flowing within the courses of the Missouri and Mississippi rivers.

Thus, it is not surprising that this river on Mars appears muted or partly erased. It probably was never very clearly delineated in the first place.

Spacewalk cut short due to spacesuit water leak

10:50 am

Today’s spacewalk at ISS to repair a failed voltage regulator of the station’s power system has been cut short because a water bubble had appeared inside one of the astronaut’s spacesuit.

The astronauts are presently in the airlock about to remove their spacesuits, so it appears they are not in danger. However, this problem is the return of the earlier water leaks inside NASA’s spacesuits, something that the agency had thought it had solved last year. If it has returned, this is of serious concern, since it suggests that they have not yet pinpointed the chronic cause of the problem.

It should be noted that the astronauts had successfully replaced the voltage regulator prior to the premature conclusion of their spacewalk. They had had other less critical tasks on their schedule which they had to forego because of the leak.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Russia trims its 10-year space plan

10:28 pm

The competition cools: Due to budget pressures, Russia has once more cut what it plans to do in its as yet not finalized 10-year space plan.

Not only do they expect to fly fewer satellites during the plan, they appear to either have dropped or are significantly curtailing their plans for their own space station after they pull out of ISS in 2024.

The corporation has also lost some of the original ambitious projects, including creation of two autonomous modules (transformable and power generating ones, ordered by the Russian Academy of Sciences), meant for the creation of a Russian orbital station. The project is absent from the latest version of the program. A transformable module was to be created in 2020-2025 and its launch was scheduled for 2025. Its service life was estimated at five years and design and manufacturing costs, 12.3 billion rubles.

In addition, it appears they are cutting back their plans for planetary research.

Most powerful supernovae ever

6:56 pm

The uncertainty of science: Astronomers have discovered the most powerful supernovae ever detected.

This one, called ASASSN-15lh, is about 3.8 billion light years away, 200 times more powerful than most supernovas, and twice as bright as the previous record holder. It shines 20 times brighter than the combined output of the Milky Way’s 100 billion stars, and in the last six months, it has spewed as much energy as the sun would in 10 lifetimes, says Krzysztof Stanek of the Ohio State University, co-principal investigator of the All Sky Automated Survey for SuperNovae (ASAS-SN) network that spotted the explosion. “This is really on steroids, and then some,” he says. “If it was in our own galaxy, it would shine brighter than the full moon; there would be no night, and it would be easily seen during the day.”

At the moment astronomers don’t really have an theory to explain how the supernovae could produce that much energy.

A detailed review of the climate data tampering at NASA and NOAA

11:16 am

Steven Goddard has once again taken a close look at the climate data gathering at NOAA and NASA and found clear evidence of tampering.

He not only documents how the scientists at these agencies have adjusted the raw data to cool the past and warm the present to create the illusion of global warming, they have done so with a limited data base.

The bulk of the data tampering is being done by simply making temperatures up. If NOAA is missing data for a particular station in a particular month, they use a computer model to calculate what they think the temperature should have been.

Those calculations are then designed to support the theory of human caused global warming, caused by increased carbon dioxide.

Goddard doesn’t just tell us his opinions, he backs up his conclusions with detailed graphs and data.

Do I accept Goddard’s conclusions entirely? Maybe. The two questions I ask that none of the NOAA or NASA scientists have been willing to answer are these:

A cold-eyed look at Trump’s actual record

10:19 am

Link here. Key quote:

While Sessions, Cruz, and others on the outside like myself were fighting the worst immigration bill of our generation in 2013, Trump was promoting the Dream Act. When it really mattered he wasn’t with us.

Moreover, what sort of judges would Trump nominate? Where does he stand on proposals to rein in the lawless courts? If he believes the courts are the law of the land, even when they violate the most fundamental rights or original intent of the Constitution, as he did with religious liberty, what will he do when the courts inevitably use the same phantom 14th Amendment legal theory to toss out his immigration proposals?

While I will vote for Trump in a heartbeat should he be the Republican candidate running against either Clinton or Sanders, he isn’t yet that candidate, and conservative voters have an obligation to look at him honestly. From my perspective, he is not the candidate I want, as he in the end will likely not really change anything as President, but instead continue the general policies that have gotten us where we are. He might make some radical changes around the edges, on hot-button issues like immigration, but overall his political philosophy is that of a traditional liberal East Coast New Yorker.

Bush, Cruz, Carson, and Sanders on space policy

10:04 am

This article takes a look at the positions on space policy of four candidates for President.

Not surprisingly, there is not much substance to what these candidates have said. They mostly mouth positive platitudes about space, and often indicate by those platitudes a general lack of knowledge about the subject.

What is more important to consider is their overall political philosophies combined with legislative actions they have actually done. Cruz for example is clearly in favor of reducing the cost and size of government. He has also made it clear by his actions in the Senate that he considers space an important national priority. These facts tell me that, should he become president he will likely move to end SLS while shifting resources to private space, since it costs a lot less and the government (and nation) will get more for its money.

Sanders meanwhile has consistently voted for a smaller space program in all his years in the Senate. As a socialist and a liberal who sides with the Democrats routinely, he, like them, has generally opposed spending any money on NASA or space, generally arguing that the money would be better spend solving problems on Earth. While he might mouth support for NASA now, I would expect him to try to kill it once in office.

Orbital ATK and SpaceX win Air Force contracts

9:42 am

The competition heats up: The Air Force has awarded Orbital ATK and SpaceX contracts to develop new rocket engines to help end the U.S.’s reliance on Russian rocket engines.

The Orbital contract is initially worth $47 million, with the company committed to spend $31 million of its own money., according to the Defense Department’s daily digest of major contract awards. Eventually the government could pay the company $180 million. SpaceX’s contract meanwhile was for $33.6 million initially for the development of its new Raptor upper stage engine, with a total government payment to be $61 million.

And that’s not all. Later today NASA will announce the winners in its second ISS cargo contract. The competitors are SpaceX, Orbital ATK, and Sierra Nevada. I am hoping the latter two win, since that would allow the construction of a fourth American spacecraft, Sierra Nevada’s Dream Chaser, capable of lifting cargo and crew into space.

Juno becomes most distant solar-powered mission

9:34 am

Scheduled to enter orbit around Jupiter in July 2016, the American space probe Juno has now broken the record as the most distant solar-powered interplanetary spacecraft ever to operate.

The previous record had been held by Rosetta. In the past most missions beyond Mars used nuclear-generated power plants, since the amount of sunlight is insufficient. However, improvements to the efficiency of solar power, combined with a lack of nuclear fuel in the U.S., has made it possible to fly missions using solar power farther from the sun.

That space junk was from Lunar Prospector

9:23 am

A research team at JPL has concluded that the unidentified piece of space junk that had been in lunar space but crashed to Earth in November was likely the engine module used by the 1998 Lunar Prospector mission.

The junk’s identity is by no means certain, but the “leading candidate” is the translunar injection module of Lunar Prospector, says Paul Chodas, an asteroid tracker at NASA’s Jet Propulsion Laboratory in Pasadena, California. The module nudged the probe out of Earth orbit and then detached from the main spacecraft, which orbited the Moon for 19 months before it was deliberately slammed into the lunar south pole in July 1999.

Speculation about the source of the debris, known as WT1190F, ran rampant even before it plummeted through the atmosphere on 13 November. The only artificial object to make an uncontrolled re-entry at a precisely predicted place and moment, it presented a unique chance to witness such an event in real time. Researchers took advantage of the opportunity, monitoring the debris from a chartered jet as well as from ground-based observatories.

Water behavior on Comet 67P/C-G

9:12 am

A new paper based on accumulated data from Rosetta has given scientists a better understanding of the behavior of water ice on Comet 67P/C-G, including the process by which it escapes and is also covered by dust on the surface.

Although water vapour is the main gas seen flowing from comet 67P/Churyumov–Gerasimenko, the great majority of ice is believed to come from under the comet’s crust, and very few examples of exposed water ice have been found on the surface. However, a detailed analysis by Rosetta’s VIRTIS infrared instrument reveals the composition of the comet’s topmost layer: it is primarily coated in a dark, dry and organic-rich material but with a small amount of water ice mixed in.

In the latest study, which focuses on scans between September and November 2014, the team confirms that two areas several tens of metres across in the Imhotep region that appear as bright patches in visible light, do indeed include a significant amount of water ice. The ice is associated with cliff walls and debris falls, and was at an average temperature of about –120ºC at the time.

Note that many media sources today are falsely reporting the “discovery” of water by Rosetta on the comet. This is ridiculous, as water has been detected there for years. To suggest that “discovery” indicates a remarkable level of stupidity and ignorance by these news organizations about science. Either they think their readers are dumb, or they themselves don’t know anything.

Unfortunately, I worry that the answer is both.

The Falcon has landed

9:07 am

SpaceX has produced a short video that recaps its last launch and the successful landing of its first stage. I have embedded it below, because it is worth seeing again as the company is preparing to do it again this weekend. It is also worth watching again to see the joyous celebration of everyone watching at the moment, all of whom know deep down that they have just witnessed a significant event in the history of the human race.

SLS still has no mission

9:04 pm

At a meeting at the Kennedy Space Center on Monday, outlining the status of the Orion/SLS program, managers admitted that the program still lacks funding for any missions past its initial 2018 unmanned test flight.

Internally, a huge amount of work is continuing to take place on providing SLS with Design Reference Missions (DRMs). However, those are only for planning purposes and the outlook continues to change, resulting in uncertainty. Numerous factors are to blame, with funding once again mentioned as an issue during the KSC meeting – citing SLS is “lacking booked missions at this time due to tight funding.”

In other words, Congress has not provided NASA any funding for any real SLS missions. I also don’t expect Congress to ever do so, since the cost per launch ranges from $3 to $14 billion, depending on how you calculate the numbers. This is in comparison to the estimated per launch cost of about $100 to $150 million for a Falcon Heavy launch, capable of putting in orbit about two-thirds that of SLS. Even a stupid Congressmen can read these numbers and figure out that they will get a lot more bang per buck dumping SLS for Falcon Heavy.

Daft Punk – Get Lucky

6:01 pm

An evening pause: Hat tip Kyle Kooy. I don’t think the Chinese military realized that they were marching to this music, but gosh darn it, they sure appear to. As Kyle noted to me, “Somebody took a Chinese military parade and set the music to the American song “Get Lucky” by Daft Punk. … [It] creates a very mesmerizing video that is both upbeat and somewhat eerie at the same time.”

Gaming Obamacare

5:14 pm

Finding out what’s in it: The Obama administration and health insurers are discovering that, because of the high cost of health insurance forced on consumers due to Obamacare, those consumers are improvising ways to “game the system”.

The article describes a whole range of tricks citizens are discovering that allow them to get insurance companies to pay for their health costs while paying those same insurance companies as little as possible. This example, which is not the focus of the story, encapsulates for me the entire insane nature of this monstrous law, forced upon us by Obama and the Democratic Party:

[Insurance companies] note many people have figured out they need pay for only nine months to get a full year of coverage. An enrollee might buy an ACA policy, get their health needs addressed and then let their coverage lapse — without having to pay the penalty for being uninsured.

It is only going to get worse. By not letting the free market function, the government is forced to ration care and impose restrictive rules, which people naturally try to improvise their way around, either legally or in a black market. The solution proposed in the article is even more restrictive rules and rationing.

The only real solution is to dump the whole thing and go back to the basic American principle of a free market. Such a system carries risk, but it forces the industry and the citizenry to find the most efficient solutions. It also depends on a very radical concept: personal responsibility.

Former Virgin Galactic employee battles company in court

9:54 am

A former employee of Virgin Galactic, in a arbitration dispute, has accused the company of lying about its spacecraft’s safety and performance.

Virgin Galactic’s former vice president of propulsion, Thomas Markusic, has accused Richard Branson’s space company of lying about the safety and performance of its SpaceShipTwo suborbital tourism vehicle. “Dr. Markusic was forced to separate from VG [Virgin Galactic] because the company was defrauding the public about the ability of the vehicles to reach space and was utilizing rocket engine technologies that have a high probability of causing catastrophic failure and loss of life,” according to the document. “VG directed Dr. Markusic to lie to customers about the performance and safety of the company’s hybrid rocket technology,” the document continues. “VG asserts that Dr. Markusic secretly plotted to start his own rocket company and exploited his position at VG; whereas, in reality, Dr. Markusic’s conscience forced him to to leave.”

Read the whole thing. It appears Markusic left Virgin Galactic to form his own company, and in doing so might have violated an anti-competition clause in his contract, resulting in the arbitration dispute. At the same time, his accusations ring true, considering these rumors had been flying about at the time and have since been more or less confirmed.

Crater close-ups from Dawn

9:38 am

Kupalo Crater on Ceres

The Dawn science team today released a set of close-up images of several craters on Ceres, showing a number of geological features similar but different than features seen in lunar craters.

The image on the right, of Kupalo Crater, shows the same kind of bright material on the rim that is seen on the floor of Occator Crater as two bright areas. The bright material is now believed to be a salt deposit leeched from beneath the surface. Other craters showed extensive fractures in their floor as well as lobes and scarps.

Was the Wow! signal from two comets?

10:35 pm

One of the most baffling radio astronomical detections, dubbed the “Wow! signal” and that some believe could have been caused by an extraterrestrial transmission, is now theorized to have been caused by two comets, not an alien civilization.

Antonio Paris, a professor of astronomy at St Petersburg College in Florida, thinks the signal might have come from one or more passing comets. He points the finger at two suspects, called 266P/Christensen and P/2008 Y2 (Gibbs). “I came across the idea when I was in my car driving and wondered if a planetary body, moving fast enough, could be the source,” he says.

Comets release a lot of hydrogen as they swing around the sun. This happens because ultraviolet light breaks up their frozen water, creating a cloud of the gas extending millions of kilometres out from the comet itself. If the comets were passing in front of the Big Ear in 1977, they would have generated an apparently short-lived signal, as the telescope (now dismantled) had a fixed field of view. Searching that same area – as subsequent radio telescopes did – wouldn’t show anything. Tracing the comets’ positions back in time, Paris says that the possible origin for the Wow! signal falls right between where they would have been.

Neither comet was known in 1977; they were both discovered in the last decade, which would mean nobody would have thought to search for them.
