Recent Kuiper Belt discoveries cast doubt a big planet exists there

The uncertainty of science: Despite predictions by some scientists that a big planet exists in the Kuiper Belt beyond Neptune, recent new discoveries of new objects there cast doubt on its existence.

If the additional big planet existed, the newly discovered objects would have shown some clustering, shepherded by its gravity.

“We find no evidence of the orbit clustering needed for the Planet Nine hypothesis in our fully independent survey,” says Cory Shankman, an astronomer at the University of Victoria in Canada and a member of the Outer Solar System Origins Survey (OSSOS), which since 2013 has found more than 800 objects out near Neptune using the Canada-France-Hawaii Telescope in Hawaii. In a paper posted to arXiv on 16 June and soon to be published in The Astronomical Journal, the OSSOS team describes eight of its most distant discoveries, including four of the type used to make the initial case for Planet Nine.

“I think it’s great work, and it’s exciting to keep finding these,” says Scott Sheppard, an astronomer at the Carnegie Institution for Science in Washington, D.C., who was among the first to suspect a large planet in the distant solar system. But he says three of the four new objects do have clustered orbits consistent with a Planet Nine. The fourth, an object called 2015 GT50, seems to skew the entire set of OSSOS worlds toward a random distribution. But that is not necessarily a knockout blow, he says. “We always expected that there would be some that don’t fit in.”

Note that I do not consider “Planet Nine” to be an accurate name for this theorized planet. Either it is #10, after Pluto, or one of a large number far more than nine, based on a new proposed and more logical planetary definition. The present definition however does not work.

Russia moves to capture the smallsat launch market

Glavkosmos, a division in Roscosmos, Russia’s nationalized aerospace industry, is working to capture a large part of the new smallsat launch industry.

Glavkosmos, a subsidiary of Russian state space corporation Roscosmos, said June 14 that it will launch 72 small satellites as secondary payloads on the Soyuz-2.1a launch of the Kanopus-V-IK remote sensing satellite, scheduled for July 14 from the Baikonur Cosmodrome in Kazakhstan.

Vsevolod Kryukovskiy, launch program director at Glavkosmos, said in a June 19 interview that the smallsat customers for that launch come from the United States, Germany, Japan, Canada, Norway and Russia. He declined to identify specific customers, although he said they include both companies and universities. The spacecraft range in size from single-unit cubesats up to a 120-kilogram microsatellite. “We’ll do the most technically challenging cluster mission ever,” he said. The satellites will be deployed into three separate orbits, after which the rocket’s upper stage will perform a deorbit maneuver.

Kryukovskiy said Glavkosmos is also arranging the launch of secondary payloads on two Soyuz launches planned for December from the new Vostochny Cosmodrome in Russia’s Far East region. “We’ll have about 40 microsats that we’ll launch from Vostochny, and that will be the first international launch from this new Russian cosmodrome,” he said.

These numbers are in the same range as when India launched 103 smallsats on a single rocket, and suggest that Russia is trying to grab the market share that the new small rocket companies are aiming at.

Arianespace gets another launch contract

Capitalism in space: Arianespace has won new contracts for two launches of its Vega rocket.

More important however was this tidbit:

And, with another two flights to geostationary orbit booked for its Ariane 5 heavy lifter, the Arianespace orderbook now stands at €4.8 billion ($5.3 billion), with 53 launches for 28 customers: 18 using Ariane 5, 25 for the mid-weight Soyuz and 10 for Vega/Vega C.

Compare that manifest with Russia’s, which now only has 15 commercial launch contracts through 2023. Compare it also to SpaceX’s which lists about 30 commercial launches, excluding its NASA cargo and crew missions to ISS.

It would appear that Russia has so far been the big loser in the new competitive launch industry. This can of course change, especially if Russia fixes its production problems, becomes a reliable launch company, and offers competitive prices.

British government to loosen regulations on space

The British government is about to propose new regulations on space to allow the operation of commercial spaceports while establishing a licensing system for the launch companies that will fly from those spaceports.

These new regulations are likely the legislation the government announced it was preparing back in February. I suspect they are, like other recent legislative proposals, trying to fit the square peg of private enterprise into the round hole of the Outer Space Treaty.

Largest quake in Yellowstone since 2014

The USGS today recorded a magnitude 4.5 earthquake at Yellowstone today, the largest since a magnitude 4.8 occurred in March 2014, and part of a continuing swarming of small quakes that began on June 12.

This sequence has included approximately thirty earthquakes of magnitude 2 and larger and four earthquakes of magnitude 3 and larger, including today’s magnitude 4.5 event.

It is hard to say whether this swarm of small quakes portend a really big volcanic event, or will simply die off in the coming days. Recent data at Yellowstone has suggested the former is possible, though not imminent.

Update of Kepler exoplanet catalog

Worlds without end: The Kepler science team has released an update of the space telescope’s exoplanet candidate list, adding 219 new exoplanet candidates.

NASA’s Kepler space telescope team has released a mission catalog of planet candidates that introduces 219 new planet candidates, 10 of which are near-Earth size and orbiting in their star’s habitable zone, which is the range of distance from a star where liquid water could pool on the surface of a rocky planet. This is the most comprehensive and detailed catalog release of candidate exoplanets, which are planets outside our solar system, from Kepler’s first four years of data. It’s also the final catalog from the spacecraft’s view of the patch of sky in the Cygnus constellation.

With the release of this catalog, derived from data publicly available on the NASA Exoplanet Archive, there are now 4,034 planet candidates identified by Kepler. Of which, 2,335 have been verified as exoplanets. Of roughly 50 near-Earth size habitable zone candidates detected by Kepler, more than 30 have been verified.

Additionally, results using Kepler data suggest two distinct size groupings of small planets. Both results have significant implications for the search for life. The final Kepler catalog will serve as the foundation for more study to determine the prevalence and demographics of planets in the galaxy, while the discovery of the two distinct planetary populations shows that about half the planets we know of in the galaxy either have no surface, or lie beneath a deep, crushing atmosphere – an environment unlikely to host life.

How cats used humans to conquer the world

Link here. The bottom line is this:

Compared to many other animals, cats have also changed very little in the domestication process. Behaviorally, they’ve become more tolerant of humans. Physically, though, they’re still about the same size and shape. They still like to pounce on small prey. “Cats have done since before they were domesticated what we needed them to do,” says Leslie Lyons, a feline geneticist at the University of Missouri. In other words, unlike dogs that herd sheep or hunt badgers, cats didn’t need humans to breed them to become good mouse hunters.

In other words, cats did what they want (as they always do), and humans paid them with food and companionship, while providing them the transportation they needed to reach every continent.

Did China experience a launch failure today?

The status of a Chinese launch attempt of a communications satellite today remains unknown, hours after launch.

China launched its seventh mission of 2017 on Sunday, lofting the Zhongxing-9A (ChinaSat-9A) communications satellite, but -unusually – there has been no official status update in over three hours since liftoff. The Long March 3B/G2 lifted off from the Xichang Satellite Launch Centre in the hills of Sichuan Province at 00:12 local time on monday (16:12 UTC, 12:12 EDT on Sunday), following on from Thursday’s launch of the country’s first space observatory.

Apparent video footage and locals on social media surprised by the rumbling of the launch vehicle confirmed liftoff. However, official confirmation of launch success, often within an hour, has not followed, bringing speculation of some degree of failure.

Nothing has as yet been confirmed, so this launch might not be a failure.

Update: A problem with the third stage placed the satellite in the wrong orbit.

Illinois facing budget collapse

Leftist governance: Having now gone three years without an official budget and having expenses exceeding revenues by large amounts on a monthly basis, Illinois now faces a budget collapse.

A mix of state law, court orders and pressure from credit rating agencies requires some items be paid first. Those include debt and pension payments, state worker paychecks and some school funding. Mendoza says a recent court order regarding money owed for Medicaid bills means mandated payments will eat up 100 percent of Illinois’ monthly revenue.

There would be no money left for so-called “discretionary” spending – a category that in Illinois includes school buses, domestic violence shelters and some ambulance services

More here. Essentially, this state, run for decades by Democrats (and Republican helpers) and their union buddies, has unfunded pension liabilities that make it impossible to pay its real bills. I saw this happen in New York City in the 1970s, after almost a century of one-party Democratic rule. Watch it happen again here, as well as in California and several other radicalized blue states. They have decided to go full socialist, and as such are guaranteed societal failure.

New smallsat rocket company plans first flight of aerospike engine

ARCA Aerospace has announced that it will perform the first test flight reaching space of an aerospike rocket engine this coming August.

ARCA Space Corporation has announced the first test-launch of its Demonstrator 3 space vehicle at Spaceport America in August. This will mark the first space flight of an aerospike rocket engine. Aerospike rocket engines are described as significantly more fuel efficient than the current engines and could make launches attempting to bring satellite payloads to space more affordable. Demonstrator 3 will perform a suborbital space flight up to an altitude of 100 kilometers above the New Mexico desert.

Their goal is to build a rocket they have dubbed Haas 2CA for the smallsat industry.

There is an interesting video at the link from the company showing their engineers hand-building this first suborbital test rocket, which the company also says is the first of a weekly series leading up to the test launch. More information about the company can be found at their website. According to their schedule, they hope to make the first orbital flight in 2018, and begin commercial operations by the end of that year.

It’s the hate, not the violence

The last few days have probably been the ugliest I have ever seen in American culture. Not only was an attempt made to commit mass murder against a group of Republican elected officials, the response from too many mainstream Democrats has generally been tone deaf and even supportive of the violence. Worse, the violence appears to be on-going, with no sign of relief.

My list is hardly complete. The stories above are only a small sampling of the ugly stuff I have read since the shooting on June 14. The best I have seen from some Democrats is a hint that maybe they have let their rhetoric get out of hand, but even here they often backtrack to blame Republicans and only Republicans for the shooting.

Are Republicans innocent here? No. The coarseness of language and increasing anger I have seen from both sides in the past six months has been appalling. Rather than respond strongly but intelligently and with civility, too many Republicans have decided they can be as harsh and as coarse and as vicious as the Democrats.

Nonetheless, the bulk of the coarseness and viciousness and violence falls mainly to the Democratic and liberal side of the political spectrum. You need only scan this list of attacks against conservatives since in the past year, many of which I have noted here on Behind the Black. The left has been getting increasingly violent, with no protest by the left’s leaders in the Democratic Party. Even an attempted mass murder seems insufficient to cause much horror or shame in Democratic and leftwing circles.

The key to all this however is the single word I have highlighted in the fourth headline link above. That word is “hate.” What is motivating all of this violence and ugliness is hate, a blind irrational emotion that now prevents these people from looking at reality coolly. Trump is “evil.” He is a “nazi.” He is an “anti-Semite.” He is “racist.” He wants to “kill sick people.”

None of this is true. Trump is surely not the most ideal person to be our president at this moment of time, but he is also not any of the terrible things the left is accusing him of being.

Facts and rational thought however no longer matter to the left. They hate, and their hatred can now be used to justify almost any act, including an attempt at mass murder. This is beyond the pale, and it is turning the left into everything it has said it opposes for the past century: bigoted, hateful, violent, and oppressive. They had better cool their minds down a bit or else they will find themselves in the middle of hellstorm, targets themselves, with no way to control it.

One more thought. Right after the Tucson attack on Congresswoman Gabby Giffords in 2011, I noted the disgusting inflammatory language of the left. They demanded civility from conservatives, while simultaneous calling for their murder. I said then that they had better tone down their rhetoric or face a firestorm that they themselves might not survive.

This behavior must stop. Violent and angry rhetoric can and will cause violence. And it probably has, considering the fact that a large number of the random violent acts in recent years have actually been committed by deranged individuals with liberal, not conservative, leanings. This is not to say that I blame the left for this violence, but that the left has as much of a responsibility as the right to think carefully about what it says, before it says it. Otherwise, they might find that they have made their less rational followers more angry than they ever imagined, or can control.

Or as Michael York says to his Nazi friend at the end of this scene from the 1972 movie, Cabaret. “You still think you can control them?”

We are now six and a half years later, and instead of toning down their rhetoric, the left has escalated it to violence and murder. They have embraced their hate, and it is making them insane.

The state of the global aerospace industry

A new European analysis of the global aerospace industry suggests it is both growing and changing significantly.

Several takeaways that indicate future trends.

  • The government space spending has been stable the past 5 years, there was a 2% drop in 2016
  • The number of nations spending money on space has grown significantly in the past decade, from 47 to 70
  • Spending is shifting from military to civilian efforts
  • Russia experienced a 25% cut in aerospace spending in 2016
  • China passed Russia in spending in 2016
  • U.S. government spending stabilized in 2016 after a 25% decline since 2010

A drop in government spending in space is not proof that the industry is shrinking. In fact, it might be a sign of robust growth, in that it is no longer necessary to depend on coerced tax dollars to finance space projects. Instead, it suggests that because there are increasing profits to be made in space, the government is being replaced by a vibrant private sector. It also suggests that the private sector is finding ways to do things cheaper, which is saving the government money and allowing it to lower its budgets.

The second bullet point above reinforces these conclusions. Even though overall government spending has been stable, more countries have entered the market. More is being done with the same amount of money, and these lower costs are allowing new players to participate. The last bullet point also supports these conclusions. Even though the report notes a significant drop in U.S. government spending on space since 2010, it is very clear to me that the industry has actually prospered in these same years, fueled by a growing private sector.

Air Force budget reveals cost differences between ULA and SpaceX

Eric Berger at Ars Technica has found that the most recent Air Force budget provides a good estimate of the price ULA charges the military for its launches.

According to the Air Force estimate, the “unit cost” of a single rocket launch in fiscal year 2020 is $422 million, and $424 million for a year later.

This is a complex number to unpack. But based upon discussions with various space policy experts, this is the maximum amount the Air Force believes it will need to pay, per launch, if United Launch Alliance is selected for all of its launch needs in 2020. ULA launches about a half-dozen payloads for the Air Force in a given year, on variants of its rockets. Therefore, the 2020 unit cost likely includes a mix of mostly Atlas V rockets (sold on the commercial market for about $100 million) and perhaps one Delta rocket launch (up to $350 million on the commercial market for a Heavy variant).

In other words, the $422 million estimate per launch is the most they will pay. Atlas 5 launches will certainly be less, about $100 to $150 million, while the Falcon 9 will likely be under $100 million. What they are doing is budgeting high so they guarantee they have the money they need to pay for the most expensive launches, usually on the Delta Heavy.

From my perspective, they are budgeting far too high, and if I was in Congress I would insist that this number be reduced significantly, especially considering this Air Force statement on page 109 of the budget document [pdf]:

The Air Force, National Reconnaissance Office (NRO), and the National Aeronautics and Space Administration (NASA) agreed to a coordinated strategy for certification of New Entrants to launch payloads in support of NSS and other USG requirements which has so far resulted in the certification of one New Entrant. The Air Force continues to actively work with potential New Entrants to reliably launch NSS requirements. The Government may award early integration contracts to ensure each potential offeror’s launch system is compatible with the intended payload. Beginning in Fiscal Year 2018, the Air Force will compete all launch service procurements for each mission where more than one certified provider can service the required reference orbit. [emphasis mine]

The “New Entrant” is of course SpaceX. They are also saying that they are going to encourage competitive bidding now on all future launch contracts.
