Very brief descriptions, with appropriate links, of current or recent news items.
In order to improve their chances for vertically landing their first stage on land, SpaceX has delayed the next Falcon 9 launch until Monday evening.
Not much to say but good luck and God speed!
I want to apologize for the lack of posting today and tomorrow. I am on a four day caving expedition to finish up a cave project I have been working on for the past four years. Thus, I was unable to do much posting on Thursday, though I probably will have time after tomorrow’s cave trip to catch up.
With a delay of the static fire test from today to tomorrow, launch of the next Falcon 9 is now questionable for Saturday.
The company has not said one way of the other, so Saturday’s launch is still possible, assuming Thursday’s static fire test comes off successfully.
The giant omnibus budget bill negotiated and announced by Congress today includes language that effectively lifts the limit on the number of Russian engines that ULA can use in its Atlas 5 rocket.
John McCain (R-Arizona) is very unhappy about this, and is threatening to ban the use of any Russian engines on any further Atlas 5 in future bills.
On the record, I make this promise. If this language undermining the National Defense Authorization Act is not removed from the Omnibus, I assure my colleagues that this issue will not go unaddressed in the Fiscal Year 2017 National Defense Authorization Act. Up to this point, we have sought to manage this issue on an annual basis, and we have always maintained that, if a genuine crisis emerged, we would not compromise our national security interests in space. We have sought to be flexible and open to new information, but if this is how our efforts are repaid, then perhaps we need to look at a complete and indefinite restriction on Putin’s rocket engines.
Whether McCain will be able to do this however is somewhat questionable. He is up for election next year, is very disliked in Arizona, and is likely going to face a very tough primary battle that he very well might lose. Even so, it really won’t do ULA much good if they get the right to keep using Russian engines. As I said earlier today, ULA’s future as a rocket company is extremely limited if it doesn’t develop a cheaper rocket. Continued use of the Atlas 5 and these Russian engines does nothing to get that cheaper rocket built.
For the first time ever astronomers have been able to predict and photograph the appearance of a supernova, its light focused by the gravitational lensing caused by a galaxy and the dark matter that surrounds it.
The NASA/ESA Hubble Space Telescope has captured the image of the first-ever predicted supernova explosion. The reappearance of the Refsdal supernova was calculated from different models of the galaxy cluster whose immense gravity is warping the supernova’s light.
What makes this significant is that the prediction models were based on the theory of gravitational lensing and required the presence of dark matter to work. That they worked and were successful in predicting the appearance of this gravitationally bent light (bent by the dark matter it passed through) is a very strong confirmation of both concepts. Up until now I have been somewhat skeptical of gravitational lensing. This confirmation removes some of that skepticism.
The coming dark age: The builders of the Thirty Meter Telescope today began removing construction equipment from the summit of Mauna Kea.
After the Dec. 2 court ruling voiding the permit, the state attorney general’s office said telescope equipment could remain on the mountain. The court sent the matter back for a new contested-case hearing. Telescope officials haven’t indicated whether they will pursue a new hearing, which could mean a construction delay of several years. [emphasis mine]
Essentially, even if the new permitting process approves the telescope, it will be a very long time before they can begin construction. And approval is certainly not guaranteed, considering the anti-white, anti-technology, and anti-civilization attitude that is clearly growing in Hawaii. I suspect that the builders of TMT are planning to get out, and not come back.
The return of the Soviet Union! After experimenting with the online broadcast yesterday of the Soyuz manned launch, Russian officials announced today that they will continue these broadcasts on future launches.
The launch from Baikonur was for the first time broadcast via the Luch (Ray) satellite retransmission system. More than 1,000 people have watched the live broadcast.
The Luch system is designed to solve the problems of relaying information of monitoring and control of low-orbit spacecraft, manned space systems, including the Russian segment of the International Space Station, and to serve in controlling launch vehicle flights using an alternative technology. The Luch is a series of geosynchronous Russian relay satellites, used to transmit live TV images, communications and other telemetry from the Soviet/Russian space station Mir, the Russian Orbital Segment of the International Space Station and other orbital spacecraft to the Earth, in a manner similar to that of the US Tracking and Data Relay Satellite System. “One of the main spheres we intend to develop is our functions of mobile communications and data retransmission, including for the broadcast of launches as the most interesting events for the promotion of space exploration,” Komarov said. According to the Roscosmos chief, the Gonets company will be engaged in the development of this sphere. [emphasis mine]
Wow! A thousand people watched the launch! Isn’t that amazing!
In other words, either they didn’t make it easy for the public to find the broadcast online, or they didn’t make it public at all and the 1,000 viewers were merely government apparatchiks. It is clear from the article that they are still working to get their communication satellite network back into operation — which crumbled in the 1980s and 1990s with the collapse of the Soviet Union — but if they can broadcast to 1000 people they can broadcast to far more than that. Hopefully after this first effort they will broaden its access for future launches, though I wonder if that will happen. All of Russian aerospace is now government-controlled, and the natural inclination of government bureaucrats is to squelch information so that people don’t see bad things happen.
The gigantic $1.1 trillion omnibus budget deal announced today by Congress leaders would increase NASA’s budget by $1.3 billion.
The increase to the NASA budget goes mostly to SLS and the planetary program. Congress also decided this year to fully fund the administration’s budget request for the commercial space budget, the first time this has happened since the program began back in 2006.
Though the increase to the planetary program as well as the funding to commercial space is good news, the fact that the Republican leadership in Congress agreed to increase spending at NASA illustrates everything that is wrong with Washington. These Republicans leaders promised they would bring fiscal common sense to Washington, cutting the budget to bring the deficit under control. You don’t do that by funding everything.
SLS/Orion is a waste of money. It will accomplish little if nothing, as it is so expensive that we can’t afford to finance any actual missions using it. It should be eliminated entirely. Instead, these guys raise its budget 68%. If they were serious about cutting the budget, they would have recognized the inefficiency and impracticality of SLS/Orion and cut it, allowing them to fund the programs at NASA that are working (science and commercial space) while simultaneously reducing the budget.
Sadly, they are not yet serious about regaining control of the budget. The public has been screaming for this to happen, and their failure to do as the public wants is a further explanation for the success in this election cycle of outsiders like Trump, Cruz, and Carson.
When the manned Soyuz rendezvoused and docked with ISS yesterday, there was a problem with the automatic docking system, requiring the astronauts to take over and manually dock the spacecraft.
Initial reports suggested the failure was with the radar system having a conflict with the communications systems on the berthed Cygnus capsule. The link above instead claims the failure was caused by a malfunction in one of the Soyuz attitude thrusters. The former would be annoying but less of a concern than the latter. A thruster malfunction is somewhat rare, and would be another indication of the serious quality control problems in the Russian aerospace industry.
The competition heats up: India today successfully launched six commercial satellites into orbit using its smaller PSLV rocket.
During the flight they also tested the ability of the rocket’s fourth stage to restart its engines in orbit, a necessary ability for later commercial launches.
The competition heats up: China has begun development of two versions of a second generation manned capsule.
Instead of the three-module arrangement of the current Shenzhou vehicle, the future Chinese crew vehicle will adopt a two-module arrangement, with a large inhabitable crew module at the front, and an uninhabitable cylindrical-shaped service module at back. The size of the re-entry vehicle will be twice of Shenzhou’s, capable of accommodating up to six crew members. A docking port and its associated docking sensors are fitted to the front-end of the crew module. The spacecraft can be fitted with two different service modules, with different propulsion systems and propellant capacities.
In other words, rather than copy and upgrade the design of the Russian Soyuz, as they did with their Shenzhou capsule, they will copy and upgrade the American Apollo capsule.
I will be doing one of my regular two hour appearances on David Livingston’s The Space Show tonight, starting at 7 pm (Pacific). We will likely spend some time talking about the election campaign in conjunction with space, along with a bunch of other topics. Should be fun.
A new government audit has found that the EPA broke the law with its aggressive social media campaign lobbying in support of the Obama administration’s proposed clean water regulations.
The Environmental Protection Agency engaged in “covert propaganda” and violated federal law when it blitzed social media to urge the public to back an Obama administration rule intended to better protect the nation’s streams and surface waters, congressional auditors have concluded.
The ruling by the Government Accountability Office, which opened its investigation after a report on the agency’s practices in The New York Times, drew a bright line for federal agencies experimenting with social media about the perils of going too far to push a cause. Federal laws prohibit agencies from engaging in lobbying and propaganda. “I can guarantee you that general counsels across the federal government are reading this report,” said Michael Eric Hertz, a professor at the Benjamin N. Cardozo School of Law in New York who has written on social media and the government.
I am sure this news comes as a complete surprise to everyone. Who ever heard of a modern government agency ignoring the law for its own benefit? The concept boggles the mind!
In the past forty years the use by scientists of descriptive words to positively hype their results in their papers has increased steadily.
Researchers at the University Medical Center Utrecht in the Netherlands say that the frequency of positive-sounding words such as ‘novel’, ‘amazing’, ‘innovative’ and ‘unprecedented’ has increased almost nine-fold in the titles and abstracts of papers published between 1974 and 2014. There has also been a smaller — yet still statistically significant — rise in the frequency of negative words, such as ‘disappointing’ and ‘pessimistic’.
…The most obvious interpretation of the results is that they reflect an increase in hype and exaggeration, rather than a real improvement in the incidence or quality of discoveries, says Vinkers. The findings “fit our own observations that in order to get published, you need to emphasize what is special and unique about your study,” he says. Researchers may be tempted to make their findings stand out from thousands of others — a tendency that might also explain the more modest rise in usage of negative words.
The word ‘novel’ now appears in more than 7% of PubMed paper titles and abstracts, and the researchers jokingly extrapolate that, on the basis of its past rise, it is set to appear in every paper by the year 2123.
This study was focused on the medical field, so it is unclear if its results could be extrapolated to other science fields. I suspect it can.
This article provides a detailed account of the political battle between ULA and Congress of its future use of Russian engines in its Atlas 5 rocket.
Congress has imposed a strict limit on the number of engines the company can use. ULA is still lobbying for an increase, claiming that the limit will mean that they will not be able to meet the government military launch needs for a few years when the engines on hand run out and its new American-built engines are not yet available.
In the long run I think this battle is irrelevant. What really matters is what it costs to launch a satellite, and ULA is simply not focused on reducing its costs. Consider this quote from the article, emphasis mine:
ULA has designed a new rocket dubbed Vulcan that features a U.S.-made engine, but this vehicle will not be available until around 2021, assuming the project gets funded — which is by no means a given.
They made a big deal earlier this year about how Vulcan will soon replace Atlas 5 at a lower cost, but it now appears that this was merely a public relations event. ULA wants someone else to pay for this new rocket, and thus has not yet committed any of its own money to begin actual development.
Other companies however are funding the development of their own new American-made rockets that will also be far cheaper to fly. Sooner rather than later our spendthrift Congress is going to mandate that the military use those cheaper rockets. If ULA doesn’t get moving it will be left in the dust, whether or not Congress allows it to use more Russian engines.
A Russian Soyuz rocket today successfully launched a new crew to ISS, including Great Britain’s first official astronaut.
Tim Peake is not the first Brit in space, but he is the first paid for by the British government. The first British citizen to fly in space, back in 1991, was Helen Sharman, whose flight was a publicity stunt mostly paid for by the Russians themselves.
The crew is expected to dock with ISS later today.
Lots of cool images! The science team running Rosetta’s high resolution camera have finally made available to the public the camera’s large archive of images.
The images cover the period 20 June 2014 – 16 September 2014, corresponding to Rosetta’s approach to the comet, arrival, and insertion into orbit.
In exchange for creating and running the mission, the scientists had been given a 12 month period in which these hi-res images belonged entirely to them. This gave them the chance to use them to publish papers documenting their discoveries. While this is a reasonable arrangement — used by most planetary missions in some manner to reward the scientists who made the mission possible — with Rosetta the hi-res images were kept so close to the vest that practically none have been seen, until now. Moreover, this release is very late, anywhere from 15 to 18 months after the images were taken, not 12.
Most other planetary missions make sure that at least some images are released as the mission proceeds, since the images were paid for by the public. The European Space Agency should take a look at its future policies for publicly-funded missions to make sure the public gets better access in the future.
The competition heats up: Russia’s Proton rocket successfully launched a military communications satellite on Sunday.
The link provides a lot of interesting information about the satellite as well as some recent upgrades the Russians have installed in Proton, but for context the last two paragraphs are probably the most important:
Sunday’s launch was the seventy ninth orbital launch attempt of 2015 and the seventh Proton launch of the year. Five of the six previous launches were successful, with May’s launch of Mexsat-1 failing to achieve orbit. Proton has had eleven failures in the last ten years, with 2009 the only year since 2005 in which it has not suffered at least one anomaly.
The next Proton launch is scheduled for 23 December, with another Proton-M/Briz-M carrying the Ekspress-AMU1 communications satellite. Details of any future Garpun launches are not available.
The launch reliability for Proton has seriously fallen since 2005, and to compete in the changing launch market they will need to fix this.
Engineers have determined that Hayabusa-2’s fly-by of Earth on December 3 successfully put the spacecraft on the right course to rendezvous with asteroid Ryugu in 2018.
The competition heats up: SpaceX’s next commercial launch of its Falcon 9 rocket, and its next attempt to land and recover the first stage, is now set for December 19.
They will also attempt to land the stage on land, not on a barge.
Curiosity has arrived at the first Martian dune ever observed up close and has begun its investigation.
The image above is a cropped version of a close up image showing the sand ripples on the surface of the dune. The press release also includes an amazing very very very close-up image of the pock-marked grain-covered surface. [link fixed]
Finding out what’s in it: A new Congressional Budget Office study has found that Obamacare will shrink the economy over the next ten years.
Not that this conclusion should surprise anyone. Tea party politicians (as well as Republicans) have been pointing out this consequence of adding new unneeded or unwanted regulations to businesses since the day Obamacare was proposed by Democrats. And from the moment the law was forced through by those Democrats the economy has remained stalled, with businesses forced to focus on avoiding the law’s unaffordable costs rather than focusing on expanding and increasing profits.
Cool movie time! The Dawn science team has released a movie compiled from images taken by the spacecraft, showing in false color the entire dwarf planet’s rotation as well as doing a fly-over of Occator Crater with its double bright spot.
I have posted the movie below the fold. The false colors illustrate the different materials so far detected on the surface, and help explain the nature and origin of the surface features.

Based on an analysis of Dawn images scientists now believe that the bright spots on Ceres are salt deposits, not water ice.
Le Corre and colleagues, using images from Dawn’s framing camera, suggest that these salt-rich areas were left behind when water-ice sublimated in the past. Impacts from asteroids would have unearthed the mixture of ice and salt. “The location of some bright spots also coincide with places where water vapor was detected by other spacecraft,” said Reddy, a PSI Research Scientist. “This gives us confidence that the bright spots are likely salt deposits left over by sublimating salty water.”
While the bright spots themselves are not ice, they are what is left over after salty water evaporates.
In a contest to pick the name of Russia’s proposed new manned capsule to replace the Soyuz the public has so far picked “Gagarin” as its favorite.
The choice is entirely fitting and appropriate. The problem is whether the Russians will have the cash to build it.
The competition heats up: The Google Lunar X-Prize has now confirmed two launch contracts for sending a privately financed and built rover to the Moon by 2017.
Moon Express is now the second company to have a launch contract for their lunar lander spacecraft verified by the X Prize Foundation. An Israeli team, SpaceIL, had its contract to launch a lander on a SpaceX Falcon 9 verified by the foundation in October. SpaceIL will be one of the primary payloads on a launch purchased in September by Spaceflight Industries that will carry about 20 other spacecraft. That initial launch contract verification allowed the foundation to formally extend the competition’s deadline to the end of 2017. Teams have until the end of 2016 to submit their own launch contracts in order to continue in the competition.
Sixteen teams remain in the competition, announced in September 2007, to land a privately-developed spacecraft on the moon, travel at least 500 meters across its surface, and return high-resolution videos and other data. Some teams are cooperating with others for launch arrangements.
The head of France’s space agency announced today that repairs to their instrument for NASA’s InSight Mars lander will be completed in time to ship the instrument to the U.S. in time for the scheduled March launch.
Briefing reporters here at the COP21 United Nations Climate Change Conference, Jean-Yves Le Gall said the leak, which compromised the required high-precision vacuum chamber carrying InSight sensors, was caused by a defective weld that is applied to close off the tank.
The leak’s cause has been identified and a new weld performed, Le Gall said. Tests to confirm the new weld’s integrity are underway and, assuming no problems, will be completed in time to ship the instrument to the United States in the first week of January. It will then be integrated into the InSight lander in preparation for the March launch.
As scheduled Orbital ATK’s Cygnus freighter has been successfully berthed to ISS.
This launch and docking is a success both for Orbital as well as ULA, both of whom demonstrated that Cygnus can be launched not only on an Antares rocket but on an Atlas 5 as well.
Japanese engineers have confirmed that Akatsuki has entered orbit around Venus and can now begin science observations.
The image on the right was taken by the spacecraft’s ultraviolet camera, and clearly shows the as-yet unidentified dark material in Venus’s upper atmosphere. These dark streaks have been seen since the first Venus fly-by in the 1960s, but no observations have been able to determine what the material is that shows up as dark in ultraviolet light.
This success is a triumph for the engineers that operate Akatsuki. Kudos to them!
New observations of the star KIC 8462852 to see if an alien civilization had produced laser signals has produced a null result, reinforcing the conclusion that the erratic dimming of the star is not caused by alien megastructures.
On six nights between October 29 and November 28, 2015, scientists searched for pulses as short as a billionth of a second at the Boquete Optical SETI Observatory in Panama, using a 0.5 m Newtonian telescope. The observatory’s relatively small telescope uses a unique detection method having enhanced sensitivity to pulsed signals. If any hypothetical extraterrestrials had beamed intentional laser pulses in the visible spectrum toward Earth, the Boquete observatory could have detected them so long as they exceeded the observatory’s minimum detectable limit.
KIC 8462852 has puzzled astronomers because it shows irregular dimming unlike anything seen for another star. The anomalous light curve was measured using NASA’s Kepler telescope, as part of its search for exoplanets. However, even though a planet the size of Jupiter would cause dimming of approximately 1%, the dimming observed for KIC 8462852 was far greater – up to 22%. Just as strange, the dimming didn’t follow the regular pattern of a planet orbiting a star, but instead was unpredictable. The best explanation to date is that the dimming may have been caused by cometary fragments in a highly elliptical orbit around KIC 8462852, intercepting starlight at the same time the Kepler mission was observing it.
