ESA commits $91 million to reusable rocket engine development

7:32 pm

The competition heats up? Despite a general lack of interest in reusability, the ESA has now committed $91 million to develop a new low cost prototype reusable rocket engine.

In an interview with SpaceNews, Airbus Safran Launchers CEO Alain Charmeau said FLPP is allocating 85 million euros ($91 million) to Prometheus to fund research and development leading to a 2020 test firing. Now that Prometheus is an ESA program, Charmeau expects more countries will get involved. “ESA will pay the contract to Airbus Safran Launchers and then Airbus Safran Launchers will cooperate with European industry, of course France and Germany, but we will have also contributions from Italy, Belgium, Sweden and probably a couple of others to a smaller extent,” Charmeau said.

This project reminds me of many NASA development projects. The agency spends the money to do a test firing, but the prototype is never used and gets abandoned as soon as the test is completed.

Things might change, however, come the 2020s. By then I think American companies will be quite successful in their effort to create reusable rockets, and that will leave Europe in the lurch competitively. Their solution at this time for combating that future competition however is not getting more competitive. Instead, as noted in the article at the link, Airbus Safran, the company building Ariane 6, wants the ESA to compel its members to use their rocket, regardless of cost.

Russian prosecutors indict four rocket engineers for Proton failure

7:17 pm

This won’t solve Russia’s problems: Russian prosecutors have recommended criminal charges against four rocket engineers for failing to properly calculate the right amount of fuel, resulting in a Proton launch failure.

According to the spokesman, Energiya department head Balakin, section head Martynov and his deputy Lomtev responsible for asdeveloping operational documentation failed to ensure that their subordinate, engineer Bolshigin, should timely adjust the calculation formula for resetting the fuel control system. “The document on the need for such adjustment was submitted to the organization’s relevant department but was written off by the engineer as fulfilled. As a result, the calculation formula remained unadjusted,” the spokesman said. “Subsequently, Balakin, Martynov, Lomtev and Bolshigin who knew for sure that the formula for the calculation of the fueling level contained incorrect data that could not be used during a rocket launch agreed operational documentation without pointing to a mistake in calculations,” the spokesman for the Prosecutor General’s Office said.

Putting these guys in prison is probably the worst thing the Russians can do. It will strike fear throughout their entire aerospace industry, causing all other engineers to take as few risks as possible, or leave the industry entirely. What the Russians should do is simply fire them, and reward those that noted the problem with promotions and increased pay.

In a truly competitive free market such a response will work, because even if the companies don’t reform themselves new companies will step forward to replace them. Russia however does not have a truly competitive free market, and so their only recourse is top-down bullying and threats. “Do it right or we will jail you!”

I should add that the company involved, Energia, has nothing to do with the recent corruption discovered in the construction of the upper stage engines for both Proton and Soyuz. That involved a different Russian company entirely.

How government wrecked the gas can

12:05 pm

Link here. This story should not surprise you. More important however are the article’s concluding words:

Ask yourself this: If they can wreck such a normal and traditional item like this, and do it largely under the radar screen, what else have they mandatorily malfunctioned? How many other things in our daily lives have been distorted, deformed and destroyed by government regulations?

If some product annoys you in surprising ways, there’s a good chance that it is not the invisible hand at work, but rather the regulatory grip that is squeezing the life out of civilization itself.

Almost all of the petty technological annoyances we struggle with today are the result of foolish federal regulation.

Almost 200 federal workers to take “civil disobedience” class

9:50 am

One hundred and eighty federal workers have signed up to take “civil disobedience” class on how to resist the Trump administration.

Dozens of federal workers have reportedly attended a support group for civil servants that serves as a forum for discussing opposition to the Trump administration. Some federal employees have already expressed defiance against the Trump administration following a gag order, which has since been lifted, that restricted the Environmental Protection Agency and departments of Agriculture and Health and Human Services from contacting the press or posting about the administration on social media.

This will not end well for these federal workers, which in the long run will be good for the American public. These people are not qualified to work in the federal government, because they think they are there to tell us what to do, rather than work for the American taxpayer who pays their salary. They will “resist”, Trump will find out who they are, and then he will fire them.

The private weather industry moves forward

9:23 am

Link here. Key quote:

Early next month, aerospace start-up Spire Global of Glasgow, UK, will send a mini-satellite into space aboard an Indian government rocket. This ‘cubesat’ will join 16 others that are beaming a new type of atmospheric data back to Earth — and some scientists worry that such efforts are siphoning funding away from efforts to push forward the science of weather forecasting. Spire will begin providing observations to the US government on 30 April.

The probes track delays in radio signals from Global Positioning System (GPS) satellites as they pass through the atmosphere — a technique known as radio occultation. Researchers can use the data to create precise temperature profiles of the atmosphere to feed into weather-forecasting models — and eventually, perhaps, climate models.

Spire and its competitor GeoOptics of Pasadena, California, are participating in a pilot project announced in September by the US National Oceanic and Atmospheric Administration (NOAA), which is under pressure from the US Congress to determine whether it can cut costs by using commercial weather data. But scientists worry that such efforts are hampering the development of radio occultation. For years, they have sought federal funding for a project to advance the technique, but Spire and its competitors say they can offer high-quality data for a fraction of the price. [emphasis mine]

The quotes I have highlighted illustrate the hidebound leftist scientific opposition to introducing private enterprise into weather research. The article, published in the journal Nature, never once articulates in any way how these private efforts will hurt scientific research. What it does show is that the private effort will cost a tenth of the government effort while getting launched much faster. The money, however, will go to these private companies, and not the scientific factions that up until now have lived on the government money train.

The complaints here are the same as those I saw in NASA back about a decade ago when NASA first considered hiring private companies to provide it cargo to ISS. This is a turf war. NOAA is now being pressured by Congress to do the same: stop building big expensive weather satellites and buy the service for much less from the private sector. The scientific community sees this as a threat to its funding and is trying to stop it.

With Republicans controlling all three branches of the federal government I think this opposition will be fruitless, and we shall see the shift to private enterprise in weather data-gathering to accelerate.

Government-owned Alaska Aerospace considers second spaceport

9:02 am

The competition heats up: State-owned Alaska Aerospace is considering opening a second spaceport outside the state and closer to the equator.

Alaska Aerospace operates the Pacific Spaceport Complex Alaska. The Kodiak Island complex is capable of polar, sun-synchronous and high-inclination orbits, but does not support the equatorial launches that make up most of the industry demand. With the new launch facility, Campbell said having equatorial launches will give the corporation a competitive advantage and also bring more customers to Kodiak.

The state no longer funds the corporation, which has never made money. Still, it now has contracts with Rocket Lab and Vector Space Systems and this new move is an obvious effort to make itself more viable.

Recovered Falcon 9 first stage prepped for launch

8:53 am

The competition heats up: SpaceX on Tuesday revealed that last week it has completed the standard static fire testing of the recovered Falcon 9 first stage that it plans to relaunch in March.

A March launch would mean an 11-month turnaround, which is far from optimal, but understandable for the first time. SpaceX’s founder and chief executive, Elon Musk, has acknowledged the company must do better in the future if resuable flight is to become economically viable. He says the next—and likely final—iteration of the Falcon 9 rocket will be optimized for reuse. “Block 5 is the final upgrade of the Falcon architecture,” he tweeted earlier this year. “Significantly improves performance & ease of reusability. Flies end of year.”

It now seems likely that SpaceX will fly the landed boosters it currently has, at most once or twice, before retiring them, instead of multiple times. Although the company hasn’t elaborated on the problems with the engines, booster structure, or composite materials that have shown wear and tear after their orbital launches and returns, Musk is confident that changes to the Block 5 version of the rocket will solve the problem. “I think the F9 boosters could be used almost indefinitely, so long as there is scheduled maintenance and careful inspections,” he has said.

In other words, SpaceX has had — for the first time in history — the opportunity to inspect a number of used first stage rockets, and that precious knowledge is making it possible for them to upgrade the stage design to make future stages more hardy. In fact, those future stages won’t be stages, but reusable vessels that SpaceX could even name if it wished.

Plotting the interstellar path to Proxima Centauri

8:40 am

Scientists have calculated the slingshot route that Breakthrough Starshot’s tiny interstellar spacecraft should take in order to reach Proxima Centauri while also gathering the maximum scientific data while zipping past the binary stars of Alpha Centauri.

The solution is for the probe’s sail to be redeployed upon arrival so that the spacecraft would be optimally decelerated by the incoming radiation from the stars in the Alpha Centauri system. René Heller, an astrophysicist working on preparations for the upcoming Exoplanet mission PLATO, found a congenial spirit in IT specialist Michael Hippke, who set up the computer simulations. The two scientists based their calculations on a space probe weighing less than 100 grams in total, which is mounted to a 100,000-square-metre sail, equivalent to the area of 14 soccer fields. During the approach to Alpha Centauri, the braking force would increase. The stronger the braking force, the more effectively the spacecraft’s speed can be reduced upon arrival. Vice versa, the same physics could be used to accelerate the sail at departure from the solar system, using the sun as a photon cannon.

The tiny spacecraft would first need to approach the star Alpha Centauri A as close as around four million kilometres, corresponding to five stellar radii, at a maximum speed of 13,800 kilometres per second (4.6 per cent of the speed of light). At even higher speeds, the probe would simply overshoot the star.

While most of this is hardly revolutionary, this is still the first time anyone has done the hard math based upon a real mission concept.

SpaceX to double leased space at Los Angeles port

10:16 pm

The competition heats up: SpaceX has requested a doubling of its leased space the port of Los Angeles in order to facilitate the return of first stages launched from Vandenberg.

The Board of Harbor Commissioners will vote at its Thursday morning meeting on a deal to enlarge Space Exploration Technologies Corp.’s footprint at San Pedro’s outer harbor. The company hopes to lease 4.6 acres of land and water area along Berths 51 to 53 for $23,735 a month, plus insurance and any incidental costs.

In addition to extra space, the lease agreement allows the company to have berthing rights, install a chain-link fence around the property, build a concrete rocket-support pedestal, and add an office trailer, guard shack and portable restrooms, according to a staff report prepared for the commission.

According to the article, the increased space is needed because of the company’s plans to launch every two weeks from its pads at Kennedy and Vandenberg.

U.S. 2020 Mars rover faces delays

9:26 pm

A new inspector general report has pinpointed a number of issues that could cause a delay in the 2020 launch of the next American Mars rover mission.

The biggest risk to the mission, according to NASA OIG, is the sampling system that will be used to collect and store samples of Martian rock and soil that a future mission will gather for return to Earth. That system, an essential part of the mission, has several key technologies that are less mature than planned at this phase of the mission’s development. “The immaturity of the critical technologies related to the Sampling System is concerning because, according to Mars 2020 Project managers, the Sampling System is the rover’s most complex new development component with delays likely to eat into the Project’s schedule reserve and, in the worst case scenario, could delay launch,” OIG stated.

I find it puzzling that the sampling system is an issue. This rover is essentially based on Curiosity, which has very sophisticated equipment for grabbing and even storing samples for periods of time. I don’t understand why such systems could not be quickly revised for future retrieval.

Nonetheless, there are other problems however.

Two instruments on the Mars 2020 mission have also suffered problems. One, called MOXIE, is designed to test the ability to generate oxygen on Mars, saw its estimated increase by more than 50 percent during its development. NASA has taken steps to reduce some of that cost growth by eliminating development of an engineering model and skipping further design improvements in one element of MOXIE.

Another instrument designed to study atmospheric conditions on Mars, MEDA, has suffered delays because of a “financial reorganization” by its developer, Spain’s National Institute for Aerospace Technology. OIG concluded in its report that MEDA is unlikely to be ready for delivery to NASA in April 2018, as currently scheduled. That could require adding MEDA to the rover later in the overall assembly process, or flying the mission without the instrument.

One of the reasons the Obama administration decided to make this 2020 rover mission a reboot of Curiosity was to save cost and development time. Thus, it does not speak well for NASA’s planetary program that they are having these problems.

Japanese experiment to remove space junk fails

7:22 pm

A Japanese experiment designed to test technology for removing space junk and flown on that country’s most recent cargo ship to ISS has failed to deploy its tether as planned.

The system, designed by the Japanese space agency (JAXA) and a fishing net company, should have unfurled a 700-meter (2,300 ft) tether from a space station resupply vehicle that was returning to Earth. According to JAXA scientists, however, the system appears to have faltered.

This only adds another technical failure to a string of technical failures by Japanese spacecraft. And even though the cargo ship operated as planned, its launch was delayed when engineers discovered a leak during testing. Overall, it increasingly appears that Japan’s space program has the same kind of quality control problems as Russia.

Some radioisotope dating might be overestimating the age of samples

7:11 pm

The uncertainty of science: New research suggests the radioisotope dating that scientists use has been overestimating the age of many samples.

The article does not indicate if this overestimate applies to all radioisotope dating or just to the strontium-86/rubidium-87 dating methods mentioned. Nor does the article detail how much of an overestimate the scientists have measured. Depending on these factors the difference — and its influence on scientific results — could be relatively small, or quite large.

Gorsuch picked by Trump for Supreme Court

6:38 pm

President Trump tonight named Neil Gorsuch as his pick to replace Antonin Scalia on the Supreme Court.

My fear that Trump would go for the more moderate Thomas Hardiman has proven unfounded. Instead, this more conservative choice once again suggests that Trump is shifting increasingly to the right.

In fact, I think the insane and insulting attacks brought against Trump by the left have actually served to make him more conservative. As Rush Limbaugh noted today,

Would you like an illustration of what I mean by Donald Trump not being ideological and how it’s a problem? He understands he has opposition. How could he not? (chuckles) I mean, I’m sure he knows that he’s got opposition. Don’t misunderstand me, now. And I’m sure that he may have had his eyes opened about some of these people. In his mind, they’re Democrats. Liberal, conservative, that’s not in his lexicon, folks. I’m not offering this as a criticism. It’s just a truth. It’s something that, if you want to understand Trump, then there’s no better deconstructor of Trump and explainer of Trump who’s not in the inner circle than me.

All during the campaign I did my best to explain to everybody — leftists, media, conservative, Republicans, Never Trumpers — who Trump is, why Trump is, why Trump was winning, who Trump’s supporters are. And the thing that I kept saying is, “He’s not ideological.” So he knows he’s got opposition, he knows Democrats, and he’s probably had his eyes opened here. I’m sure that over the course of his life some of these people now calling him names trying to destroy him have been his friends. So his eyes are no doubt opened. I don’t doubt that.

When Trump first announced his candidacy, everything he did and said at that time fit with Limbaugh’s analysis, except that at the time I think Trump was much more middle of the road. I think he truly believed his liberal background working closely with Democrats would make them treat him decently. Instead, they have come at him guns blazing, calling him the worst sort of names, making the most vile accusations against him, and even attacking his family and his children.

The result? Trump has, as Limbaugh notes, had “his eyes opened.” He might not be a philosophical conservative, but more and more it appears that he recognizes the corrupt hate coming from the left, and is less and less inclined to give them an inch. Instead, he moves rightward. I also think this is the same pattern we are seeing nationwide among voters.

Right now the Democrats in the Senate look like they are planning to copy the strategy to try to block Trump’s Cabinet appointees used by Texas and Wisconsin Democrats in 2003 and 2011 respectively.

This is not the first time Democrats have blocked a Republican majority from proceeding by refusing to take their seats and thus denying Republicans a quorum. In 2003, 11 Democrats in the Texas House of Representatives literally fled the state for weeks in order to prevent a redistricting plan favored by Republicans. Eventually, one of them returned and the redistricting plan was passed. More recently, in 2011, Wisconsin Democrats fled to Illinois for three weeks to avoid a vote on Republican Gov. Scott Walker’s budget bill because of provisions that were opposed by Wisconsin unions. However, the GOP-controlled legislature defeated the Democrats’ maneuvers by separating these bills from the budget and passing them separately.

In both cases, the Democrats not only failed to win, but their actions caused the voters to move to the right, voting in more Republicans and significantly reducing Democratic influence in both these states. With Wisconsin the result has been the shift of that state from a blue to a red state.

They say that Einstein called insanity doing the same thing over and over again and expecting a different result. I think this nicely defines the Democratic Party these days.

“We need to start killing people.”

4:27 pm

This story has been making the rounds, but I held off posting it because I wanted some confirmation that it was real. It is. At a anti-Trump rally this weekend in Seattle one speaker made it very clear what she wanted:

“F**k white supremacy. F**k the U.S. empire” the speaker attacks capitalism. “You know what America thrives off of? Capitalism,” the speaker says, adding, “We use our mother=f**king, f**king black and brown bodies to live and survive while white people own f**king properties after that.” But the speaker has a solution for this problem, “So you know what we need to do? We need to start giving f**king money.” The rant continues, “White people, give your f**king money, your f**king house, your f**king property, we need it f**king all. You need to reparate black and indigenous people right now.”

A minute or so later, the speaker takes it up a notch saying, “And we need to start killing people. First off, we need to start killing the White House. The White House must die.” [emphasis mine]

The worst part? The speaker claimed she was a preschool teacher who intended to “f**king radicalize mother-f**king four year olds and five year olds.” Imagine her as the teacher of your toddler. Every other word is a curse word, and the words in-between are filled with hate.

After the Tucson shooting in 2011, the left made a big deal about the terrible incivility of the right. Obama even came to Tucson and gave a speech about the need for civility. The trouble is, the left never intended to rein in its own incivility. That crudeness to them is perfectly okay. Their goal was merely to shut down any opposition. Now they are moving to escalate their own crudeness towards violence, because no opposition to them can be tolerated.

And people wonder why I use the word fascism to describe this behavior.

India to launch spare GPS satellite because of single satellite failure

8:42 am

Because of the failure of the atomic clocks on one of its GPS satellites have failed, India now plans to launch one of their spare satellites to increase the system’s redundancy.

The article does not say whether they will make any changes to the clocks on the spare satellite, which are the same as the failed clocks on the Indian satellite and were all built by the same European company that built the clocks on Europe’s Galileo GPS satellites that are also failing.

Trump fires acting AG for refusing to defend his executive order on immigration

8:05 pm

At last! President Trump this evening fired the acting attorney general because of her announcement earlier today saying that the Justice Department would not defend in court his executive order on immigration.

The Trump announcement:

The acting Attorney General, Sally Yates, has betrayed the Department of Justice by refusing to enforce a legal order designed to protect the citizens of the United States. This order was approved as to form and legality by the Department of Justice Office of Legal Counsel.

Ms. Yates is an Obama Administration appointee who is weak on borders and very weak on illegal immigration.

It is time to get serious about protecting our country. Calling for tougher vetting for individuals travelling from seven dangerous places is not extreme. It is reasonable and necessary to protect our country.

Tonight, President Trump relieved Ms. Yates of her duties and subsequently named Dana Boente, U.S. Attorney for the Eastern District of Virginia, to serve as Acting Attorney General until Senator Jeff Sessions is finally confirmed by the Senate, where he is being wrongly held up by Democrat senators for strictly political reasons.

For more than a quarter century I have watched Republican leaders back down the instant a Democrat whined at them. Every. single. time. This time is different. Trump is not a fearful politician. He is a businessmen, an executive, and someone who expects his employees to support his actions. My first reaction when I read Yates statement earlier today was, “Fire her!” I then laughed because I haven’t seen that common sense reaction from a Republican for decades. I have seen it now.

There is still no guarantee that Trump’s policies or actions are going to be very conservative. For example, the one person out of five listed for possible Supreme Court nominee that I have found very questionable has now risen to the top of the list. Yuch. Nonetheless, Trump seems determined to make significant and positive changes in a number of areas, from immigration to environmental policy and administration. If he only does these things, he will have accomplished much.

Update: State Department officials are putting together a memorandum that will announce their opposition to President Trump’s executive order on immigration. I wonder how long these individuals will survive working for Trump after they do this.

New close-ups of Saturn’s rings

1:00 pm

New close-ups of Saturn’s rings, taken during one of Cassini’s recent ring-grazing orbits, have now been released.

They have released four different images, all at a higher resolution than any previous image. Even so, the individual particles in the rings remain unresolved. Instead, many different intriguing patterns are observed, once again suggesting that though the rings are made of many solid particles, they behave as a unit more like a liquid.

Iran tests ballistic missile despite UN ban

9:52 am

Does this make you feel safer? In direct defiance of a UN ban on such tests, Iran on Sunday completed a new test of a medium range ballistic missile.

The Khorramshahr medium-range ballistic missile flew 600 miles before exploding, in a failed test of a reentry vehicle, officials said. Iran defense minister Brigadier Gen. Hossein Dehqan said in September that Iran would start production of the missile.

I am very curious what Trump will do to try to rein in Iran. I suspect his options will be as limited as Obama’s were, except that he is not likely to sign any make-believe nuclear deals, as Obama did.

A review of Trump’s first 17 executive orders

9:04 am

Link here. The leftwing gnashing of teeth over Trump’s first actions since becoming president have routinely been based not on reality but on their false bigoted perceptions of Trump. The review at the link reveals how incredibly ordinary almost all of Trump’s initial actions have been. Most have been similar to the actions of past newly arrived presidents, from both parties. Many are no more than memos giving his subordinates guidance on what they should do.

Most disturbing has been the uproar over Trump’s suspension of the refugee programs from the seven Middle Eastern Arab countries. He hasn’t banned Muslim immigration. He hasn’t banned travel by those with legitimate green cards. All he has done has taken the seven countries listed by the Obama administration as the worst sources of terrorism and temporarily suspended any immigration from those countries pending a review of the vetting process. This seems completely reasonable, especially considering the number of terrorist attacks the west has experienced in recent years coming from immigrants from these countries. For politicians and academics and entertainers to try to turn this into something it is not out of what seems a blind hatred of Trump tells us how much western intellectual society has declined in recent years.

Next Falcon 9 launch delayed as SpaceX rearranges manifest

8:13 am

Because the launchpad at Kennedy is not quite ready for the planned February 3 launch of a commercial satellite, SpaceX has rearranged its launch manifest to switch that launch with the next Dragon mission to ISS, essentially delaying their next launch by two weeks.

With [launchpad] 39A still not ready to debut in its new role with SpaceX, the first mission set to launch from this pad – the Falcon 9 launch with EchoStar 23 – was pushed to the right a number of times. Although 39A is very close to being ready to conduct launches, EchoStar 23’s launch date was deemed to be too close to the mid-February target for the CRS-10 Dragon mission.

SpaceX and NASA discussed the situation on Friday night, before deciding it would be prudent to place EchoStar 23’s launch after CRS-10, allowing engineers to finalize modification and checkout work on the famous pad and simultaneously avoid a potential delay to the important Dragon mission to the Station.

The real problem here is that SpaceX had planned to have two working launchpads by this time, but doesn’t because their first pad was damaged in the September 1 Falcon 9 launchpad explosion. The consequences is that, for at least the next month, they will not be able to set a pace of a launch every two weeks.

Soyuz launches successfully from French Guiana

8:53 am

A Russian Soyuz rocket, built for Arianespace and launched from French Guiana, successfully placed a commercial satellite in geosynchronous orbit on Friday.

The launch has some significance. First, it was the first time a Soyuz rocket placed a payload into geosynchronous orbit. Second, the payload was the first satellite built by a German company in more than 25 years

Finally, and most important, it demonstrated that at least one configuration of the Soyuz rocket is still operational as Russia investigates the corrupt practices at the company that has been building upper stage engines for both its Soyuz and Proton rockets.

Update: Russia has revealed that this on-going investigation will now delay the next Proton rocket launch for 3.5 months. This means that launch will occur sometime in May, and will occur just weeks short of a full year after the last Proton launch on June 9, 2016.

A Saturn moon makes waves

9:57 am

Daphnis makes waves

Cool image time! The image above, taken on January 16, 2017 during one of Cassini’s ring-grazing passes as it enters its last year at Saturn, has been reduced and cropped to post here. It shows clearly the waves caused by the gravity of the moon Daphnis as its travels within a gap in the rings of Saturn.

Daphnis (5 miles or 8 kilometers across) orbits within the 42-kilometer (26-mile) wide Keeler Gap. Cassini’s viewing angle causes the gap to appear narrower than it actually is, due to foreshorteneing. The little moon’s gravity raises waves in the edges of the gap in both the horizontal and vertical directions.

The image also shows many details about Daphnis itself, including a ridge at its equator that is thought to be an accumulation of material gathered from the rings.

The strangeness of Saturn’s rings is well illustrated here. Though made up of many solid particles, as a group the rings act almost like liquid. Note for example the ring on the far side of Daphnis. Its edge gets pulled out slightly as the moon goes by, but then the gravity of the rest of the ring pulls it back.

The universe is a wonderful place, as it is. No need to make up stuff (such as faces on Mars or fake civilizations on the Moon), as our imagination is probably insufficient to match the weirdness that is really out there.

Trump threatens to “send in the Feds” to control Chicago violence

9:24 am

Not good: In a tweet late Tuesday President Trump threatened to send federal officials to Chicago if that city doesn’t do something to reduce its out-of-control homicide rates.

No one knows what Trump really meant, since this was merely a tweet on Twitter, but to suggest that he thinks the federal government has a place fixing local police crime is very inappropriate. Even if the federal government succeeded once in shutting down Chicago’s crime rate, it would set a bad precedent, expanding terribly the power of the federal government into very local matters.

Trump has enough problems to fix at the federal level, in his own executive branch. He should stay focused on that.

Giant networks of fake twitter users discovered

9:17 am

Why I don’t use Twitter: Researchers have discovered the existence of large networks of fake twitter accounts, some numbering in the hundreds of thousands.

The largest network ties together more than 350,000 accounts and further work suggests others may be even bigger. UK researchers accidentally uncovered the lurking networks while probing Twitter to see how people use it. Some of the accounts have been used to fake follower numbers, send spam and boost interest in trending topics.

What this story tells me is that almost everything you read from Twitter is not to be trusted.

Google Lunar X-Prize finalists named

9:03 am

The competition heats up: The five finalists for the Google Lunar X-Prize have now been set.

Five teams remain in the running: Israel’s SpaceIL, Florida-based Moon Express, an international team known as Synergy Moon, India’s Team Indus and Japan’s Hakuto.

SpaceIL plans to fly on a SpaceX Falcon 9 rocket, which recently returned to flight following a launch pad accident. Team Indus and Hakuto will share a ride on an Indian PSLV launcher. Moon Express is banking on a launch from startup Rocket Lab, which is developing a small rocket called Electron. Whether it wins the XPrize or not, Moon Express is building a business to provide lunar transportation and services, such as research and mineral extraction, Chief Executive Bob Richards said in an interview. Synergy Moon is counting on one of its partners, Mojave, Calif.-based Interorbital Systems, for its launch aboard a new rocket known as Neptune.

To win, one of these teams must fly its mission before the end of 2017.
