North Korea’s dictator Kim Jong Un meets with South Korean delegation

In a sign that he is backing off his previous and long maintained belligerent stance, North Korea’s dictator Kim Jong Un met with a South Korean delegation on March 5.

The above link is a press release by a North Korean news source, so it is hardly informative. This Reuters story has some information from the South Korean delegation:

Next month, North Korea and South Korea will have the first meeting between their leaders since 2007 at the border village of Panmunjom, said Chung Eui-yong, head of the South Korean delegation. “North Korea made clear its willingness to denuclearize the Korean peninsula and the fact there is no reason for it to have a nuclear program if military threats against the North are resolved and its regime is secure,” Chung told a media briefing.

Chung cited North Korea as saying it would not carry out nuclear or missile tests while talks with the international community were under way. North Korea has not carried out any such tests since last November. North Korea also is willing to discuss normalizing ties with the United States, Chung said.

This sudden willingness to talk, after more than a decade of war talk, strongly suggests that Trump’s hardline position, which subsequently forced China and others to follow, has had an effect.

Twenty-year-old sues Dick’s for refusing to sell him gun

Pushback: A twenty-year-old in Oregon has sued Dick’s Sporting Goods for refusing to sell him a rifle, based on his age.

The plaintiff, Tyler Watson, claims he faced “Unlawful Age Discrimination.” Watson attempted to buy the rifle “on or about February 24” at a Medford, Oregon, Field and Stream store. (Field and Stream is subsidiary of Dick’s.) Watson’s suit, filed in the Circuit Court of Oregon for the County of Jackson, says a store employee refused the purchase and indicated, “He would not sell [Watson] any firearm, including rifles and shotguns, or ammunition for a firearm, because [Watson] is under 21 years old.”

The employee referenced Dick’s recent policy shift, disallowing firearm sales to anyone under 21, and cited the policy as the reason for denying the sale.

Watson’s suit alleges that Dick’s policy violates Oregon law against age-based discrimination for people 18 years and older in places of public accommodations. State law includes prohibitions against discrimination in stores that are open to the general public.

Watson has also sued Walmart, for the same reasons.

The irony here is that Oregon, a decidedly liberal state, was very quick to pass age discrimination laws in the past, a traditional tactic of the left to create groups of victims it can utilize politically in order to maintain its power. Watson here is now using those laws against them.

ESA successfully tests an air-breathing ion thruster

Engineers from the European Space Agency (ESA) and an Italian company have successfully tested a prototype of an ion engine that would obtain its fuel from the thin atmosphere available in low Earth orbit, thus allowing it to operate practically indefinitely.

From the press release:

Replacing onboard propellant with atmospheric molecules would create a new class of satellites able to operate in very low orbits for long periods. Air-breathing electric thrusters could also be used at the outer fringes of atmospheres of other planets, drawing on the carbon dioxide of Mars, for instance. “This project began with a novel design to scoop up air molecules as propellant from the top of Earth’s atmosphere at around 200 km altitude with a typical speed of 7.8 km/s,” explains ESA’s Louis Walpot.

Think about it. You supply your planetary probe one or more of these engines, and once it reaches orbit around its target it has an unlimited fuel supply to do research just about forever. More important, such technology when further refined is going to enhance human exploration as well. For example, rather than use the atmosphere at it arrives, later designs could simply dive into the atmosphere to get the spaceship’s tank refilled. Such engines would make spacecraft free from the tether of Earth.

Ground too hard for Curiosity’s drill

A second drill attempt by Curiosity, using an improvised drilling technique designed to bypass the failure of the drill’s feed mechanism, once again failed to drill deep enough to obtain a sample.

After two drilling attempts, Curiosity’s drill was not able to dig into the bedrock sufficiently to collect a sample of rock at this location. Curiosity’s engineers are continuing to refine the new drilling method. In the future, this might include adding percussion, which could enable drilling into harder rock.

Either the ground on Vera Rubin Ridge is too hard for Curiosity’s drill, or the new drilling technique does not allow the drill to push with the same force as previously. The update at the link implies the former, but I suspect the latter is a factor as well.

SpaceX successfully launches commercial communications satellite

SpaceX tonight successfully launched a commercial communications satellite. They did not recover the first stage because the seas were too rough to send out the drone ship.

The leaders in the 2018 launch standings:

7 China
5 SpaceX
3 Japan
3 ULA
2 Russia

Though I have removed Rocket Lab as an American company, crediting it instead to New Zealand, the U.S. still has 8 successful launches total, one more than China.

Bi-partisan group of senators back bill to deny citizens their second, fifth, sixth, and seventh amendment rights

Fascists: A bi-partisan group of senators — Heidi Heitkamp (D-North Dakota), Jeff Flake (R-Arizona), Susan Collins (R-Maine), Pat Toomey (R-Pennsylvania), Martin Heinrich (D-New Mexico), Tammy Baldwin (D-Wisconsin), Angus King (I-Maine), Bill Nelson (D-Florida), and Joe Manchin (D-West Virginia) — have introduced a bill that would deny any citizen the right to buy a gun if they happen to be put on the no-fly list by some Washington bureaucrat, thus denying them their second, fifth, sixth, and seventh amendment rights.

As noted at this link,

Watch lists are inexact tools for law enforcement, after all, not a way to adjudicate rights. Most of the names on the watch lists, and the reason those names appear on those lists, are known only to government officials. If you’re one of the hundreds of thousands of innocent people unlucky enough to be capriciously tagged by law enforcement, you can only extricate yourself after an expensive and byzantine process that is often beyond the reach of an average a law-abiding citizen. Which is almost surely the point. As far as we can tell, nearly 300,000 names aren’t even vaguely associated with potential terrorist organizations. Yet, in this proposed legislation, sponsored by Sens. Susan Collins (R-ME) and Heidi Heitkamp (D-ND), senators demand that Americans ask for permission before practicing their constitutional rights.

Then there is the question of how we define a potential terrorist in the future? The listmakers won’t say. How about Democrats? As others have noted, liberals regularly accuse the National Rifle Association (and thus gun owners) of being complicit in terrorism. Democratic Sen. Chris Murphy has argued that Republican who fail to support bypassing due process “have decided to sell weapons to ISIS.” Kathleen Rice, who sits on the House Homeland Security Committee, contends that Dana Loesch and “the NRA are domestic security threat” for practicing their First Amendment rights. Excuse me if I don’t trust these people to dictate whose rights should be protected. [emphasis mine]

More important, if the people on these watch lists are so dangerous, according to these senators, why are we simply denying them the right to buy a gun, without due process? Shouldn’t we round them up immediately and put them in concentration camps, just make sure they can’t do anyone any harm?

Heitkamp, Manchin, and Nelson, all face stiff challenges in the 2018 elections. I would not be surprised if they find themselves all out the door. Flake, who ran for the Senate based on his a budget-cutting record in the House, is nothing but a corrupt backstabber, and has thankfully said he is not running for re-election. That’s four out of these nine. I wonder what can be done about the other five.

I want everyone to read the highlighted text above very carefully. It documents how the left and Democrats are becoming very nonchalant about demanding the nullification of the Constitutional rights of anyone who disagrees with them. This is not to be taken lightly. They mean it. Give them a victory in an election and they will begin to do it.

American embassy opens in Jerusalem in May

In order to coincide with the 70th anniversary of Israeli independence, the Trump administration today announced that the American embassy will officially open in Jerusalem in May 2018.

Officials told Fox News the embassy would initially be located in the neighborhood of Arnona on a compound that currently houses the consular operations of the U.S. Consulate General Jerusalem. Initially, the embassy will consist of the Ambassador and a small team. Nauert said that the Consulate General would “continue to operate as an independent mission with an unchanged mandate” from its Agron Road location.

An official also told Fox News that the hope is for the U.S. to develop only a “footprint” there in May, with a target of a fuller complement and facility by the end of 2019.

Much of this is therefore symbolic, but symbolism in diplomacy is often everything. More important, this action lends weight to the likelihood that Trump is firm in keeping this campaign promise, a campaign promise that every past Republican president since the 1990s failed to keep.

You might not like Trump, but an honest appraisal has to give him credit for one thing. He keeps his campaign promises. He said he’d cut taxes. He cut taxes. He said he’d shut down illegal immigration. Everything he has done indicates a sincere effort to do so. He said he’s cut regulation and neuter the EPA. He has done so, in a manner not seen by a president in my lifetime.

While I can certainly criticize Trump for a number of things, including his unwillingness to really cut spending and waste in the federal government, I would dishonest if I did not credit him for this.

Utah concealed-carry class for teachers largest ever

A Utah concealed-carry class, organized for teachers and college students, had the largest sign-up ever, about 1,000 people total, with many coming in direct response to the Parkland shooting.

About 1,000 people signed up, which organizers said likely made it the largest concealed carry course ever taught in the state. Concealed firearms may be carried with a permit inside all Utah public schools and universities. “It’s been a very positive reaction,” said Sam Robinson, co-owner of Utah Gun Exchange, which organized the event in the wake of the Florida massacre. “There are a lot of people who want to learn more, who want to become more engaged and take a more active role in the defense of our schools — so they at least have the opportunity to be the last line of defense.”

On the four-hour class agenda: firearm safety, handling, transportation, storage and laws, plus basic tactical skills that instructors said might come in handy during a school shooting. Media were not allowed inside, to “protect the privacy of people who are here,” Robinson said, adding organizers wanted to ensure attendees were not “shamed” for their beliefs about gun rights. [emphasis mine]

The two highlighted quotes are important. First, if safety is a big concern for your kids, Utah is clearly where you should send them. Ordinary citizens, properly trained, are allowed the tools to defend themselves and others.

Second, it is entirely understandable for the organizers to restrict the media’s access to the classes. It would not be there to report, but to continue the hatefest against ordinary Americans who wish to exercise their second amendment rights, in a responsible manner.

I have taken Arizona’s concealed carry class, as well as attended gun training classes in Maryland. Attendance ranged from 15 to 50. A turnout of 1000 people for a single class is astonishing. It is a strong indication that the winds favor the idea of properly allowing teachers and college students the ability to defend themselves. It also suggests that, should politicians decided to eliminate gun-free zones, they would score political points, even as the media and the left were certain to go insane over it.

America’s first space weatherman gets to say “Go!” again

John Meisenheimer, the launch weather officer who gave the go-ahead for the first successful American satellite launch, Explorer 1 on January 31, 1958, was honored at the 60th anniversary of that first launch by having him to give the go-ahead for GovSat 1, launched on January 31, 2018.

The story is very touching, especially because Meisenheimer had scrubbed the Explorer 1 launch twice previously because he did not trust the weather. In 1958 he alone had that power, and no one questioned it. When the rocket flew, it was because he had decided the weather was no longer an issue.

China’s space station delayed to 2020

Because of redesign work required on its Long March 5 rocket, China revealed today that the launch of the first module, Tianhe, of their planned space station, has now been set for 2020.

Launch of Tianhe had earlier been planned for 2018, but the launch failure in July last year of the Long March 5 rocket, a heavy-lift launch vehicle required to loft the 20-tonne space station modules to low Earth orbit, meant a delayed schedule.

The next attempt at a Long March 5 launch, which will send a large telecommunications satellite into a geostationary transfer orbit, will take place from Wenchang in the second half of 2018. If that is successful, it will pave the way for a test launch of the low Earth orbit variant of the rocket, the Long March 5B, around June 2019. The follow-up flight will then launch the Tianhe module, now set to take place in 2020.

During the Soviet era, it was not unusual for the Russians to suddenly invent a new variant of a rocket or space capsule in order to provide cover for their need to redesign or fix problems. That is what I think is happening here. Until the still unexplained launch failure of Long March 5 in July 2017, I had never heard of a Long March 5B. It was the Long March 5 that was going to do all the heavy lifting.

Now we suddenly have a Long March 5B, a “low Earth orbit variant of the rocket.” I increasingly suspect that the problems with Long March 5 were so serious that they have caused a complete redesign. It was able to get its first payload into orbit, but not its second. The failure was not accompanied by any catastrophic event, which suggested, based also on later reports, that the rocket’s first stage engines simply under-performed significantly. I wonder now if what China is doing now is making that weak rocket the 5B, while they redesign the 5 so it can lift the big payloads required.

We also cannot trust them entirely with the naming they use of their rocket for each launch. The next Long March 5 launch in 2018 might actually be the 5B variant, without the name, and the so-called first test of the 5B in June 2019 might actually be the first test of the full powered 5.

Wheels within wheels!

Testing of Blue Origin’s BE-4 rocket engine continues

Though he released few details, a Blue Origin company official noted at a conference last week that the company has been continuing its tests of the BE-4 engine.

“We’re getting longer duration burn times. We’re going though validating the turbomachinery very closely,” said Jim Centore, group lead for orbital mission operations at Blue Origin, during a panel discussion on launch systems at the conference. Centore didn’t disclose many details about those tests, such as thrust levels or the burn times, either of individual tests or cumulatively. “We’re continuing to make good progress,” he said. “We’ll continue that for the next several months.”

The BE-4 is the linchpin for numerous other future rockets. Blue Origin wants to use it for building its New Glenn rocket. ULA is considering it as the first stage engine for its Vulcan rocket. In both cases, design and construction of the rockets themselves can’t really proceed until the engine is locked down.

The left’s hatefest continues

Just thought I put up a few more links of stories illustrating the hate, intolerance, and bigotry of the left.

Note that the last four stories demonstrate the bigotry that is ingrained within the Democratic Party itself, while the first two stories demonstrate the cultural intolerance of the supporters of that party. Team them up, give them some election wins, and no one should be surprised when they start arresting their political opponents.

Expect more stories in the same vein in the coming days.

Mars Reconnaissance Orbiter comes out of safe mode

On February 23 the Mars Reconnaissance Orbiter (MRO) engineering team was able to bring the spacecraft out of safe mode, after a low battery voltage reading caused it to shut down.

Mission team members brought MRO out of safe mode on Friday (Feb. 23), NASA officials said. The orbiter seems to be in good health overall; the battery voltage is back to normal, MRO is communicating with Earth, and temperatures and power levels are stable, agency officials said.

But MRO’s handlers haven’t put the orbiter back to work yet. “We’re in the diagnostic stage, to better understand the behavior of the batteries and ways to give ourselves more options for managing them in the future,” MRO project manager Dan Johnston, of NASA’s Jet Propulsion Laboratory in Pasadena, California, said in a statement. “We will restore MRO’s service as a relay for other missions as soon as we can do so with confidence in spacecraft safety — likely in about one week. After that, we will resume science observations.”

Overall this sounds like very good news.

Webb faces more delays, cost overruns

A new GAO report released yesterday says that the James Webb Space Telescope faces further delays and cost overruns.

This is par for the course. Webb has become an incredible boondoggle. I hope it eventually gets launched and works, but its gigantic cost, $8 to $9 billion (compared to an original $1 billion budget), and delayed schedule suggests that this was not the right way for NASA or the astronomical community to build its space telescopes. Further, this quote from the story suggests something fundamentally wrong:

The GAO report also noted that, during the sunshield deployment exercises, Northrop discovered several tears in the material which it attributed to “workmanship error.” Those tears can be repaired but may consume more schedule reserve.

Is this thing really going to work? I really hope so, but have been increasingly doubtful as the delays and problems have piled up.

Meanwhile, NASA and the astronomical community is still pushing to get funding for its next “Webb,” the Wide-Field Infrared Survey Telescope (WFIRST). This project, similar in scope as Webb, is hardly off the ground and already has budget overrun issues. The Trump administration recommended cancelling in its budget proposal earlier this month, but I would be surprised if that recommendation goes through, considering the pork this new project represents.

Curiosity attempts to drill with improvised technique

The Curiosity engineering team has made the first attempt to drill in more than a year, using an improvised technique that has the rover arm push the bit into the ground rather than its presently non-function feed mechanism.

This early test produced a hole about a half-inch (1-centimeter) deep at a target called Lake Orcadie — not enough for a full scientific sample, but enough to validate that the new method works mechanically. This was just the first in what will be a series of tests to determine how well the new drill method can collect samples. If this drill had achieved sufficient depth to collect a sample, the team would have begun testing a new sample delivery process, ultimately delivering to instruments inside the rover.

According to the mission update page, for some reason the drill was unable to penetrate the ground very deeply.

They plan to do more tests, with the goal of eventually getting a hole deep enough to provide good samples.

“They don’t hate the NRA. They hate you.”

Link here. As a conservative who has worked first in the film business, then as a college teacher, and finally as a science journalist and space historian, all communities dominated almost exclusively by leftists, I can tell you that Schlichter is not exaggerating. The recent scapegoating of the NRA, which had nothing to do with the Parkland massacre, illustrates this. So have every single previous hate spasm from the left in the past few years

The Democratic Party now wishes to repeal three of the Bill of Right’s ten amendments. They have already nullified the ninth and tenth. Be prepared for great evil should they win future elections.

Parkland Underscores How Americans Pay For Garbage Government While Doing Its Job Ourselves

Link here. Essentially, the article outlines how, at every single level, government in the U.S. is failing, while demanding more money and more power as a reward. Parkland is only a recent single example.

Each day Americans wake up to hear new revelations of government incompetence that enabled the Parkland, Florida school shooting. First it was the Federal Bureau of Investigation’s failure to follow existing protocols to investigate a highly detailed tip that the shooter was planning and had the means to do exactly what he did. The FBI and local police received at least four separate tips warning of the shooters’ plans and means, and local police had received 45 calls summoning them to the family’s home since 2008.

Then we learned of the police officer — the only person initially onsite able to return the shooter’s deadly force and tasked by his salary-paying community with doing precisely that — hesitated for approximately four minutes to enter the high school as students lay dying. Then local sources told reporters three other Broward County police officers joined that onsite officer in hiding behind their vehicles until police from another jurisdiction showed up. Reports say the Broward County police didn’t even follow the others inside.

Then it was that police didn’t know they were watching the wrong security tape, putting them off the shooter’s whereabouts by 20 minutes, leaving a mass murderer to endanger more people longer. To add insult to literal injury, the hesitating onsite school police officer, Scot Peterson, was allowed to resign and will receive a lifetime public pension of approximately $60,000 a year plus benefits.

The list of failures above for Parkland is actually not complete. However, they do provide a metaphor for our government, which functions about as badly in every other area as well. Readers of Behind the Black will of course be aware of SLS/Orion, NASA’s own failed boondoggle that will never get us into space.

What must happen is a major house-cleaning. Many thought Trump would do it. I continue to see Trump as a transitional figure, willing to slash and burn in a few areas (EPA) but not in most other areas (FBI, Justice Department, NOAA, NASA, to name a few). Essentially, almost everyone working in Washington needs to be fired. Many can reapply for the work, but no one should be guaranteed a job.

Unfortunately, I do not see this happening. Instead, I see this cabal in Washington teaming up with corrupt elected officials and a corrupt national press to defend their positions of power, even as they fail again and again to simply do their jobs. Witness for example how so-called conservative Senator Ted Cruz (R-Texas) has teamed up with Senator Bill Nelson (D-Florida) to criticize the mere suggestion by the Trump administration that ISS will be transitioned to private hands by 2024, no longer getting federal funds.

This is just one example. The power in Washington is deep and profound, and the people who have it will not give it up lightly.

Justice Dept faulted for lack of progress in Awan IT scandal

Working for the Democratic Party: The Justice Department has apparently worked to stall or stonewall the investigation into the Imran Awan IT hacking scandal that allowed Pakistani nationals access to secure computers of numerous Democratic congressmen.

The OIG [House Office of the Inspector General] alleged Imran Awan and his family members logged into servers of congressmen for whom they did not work, logged in using members’ personal usernames, covered their tracks, and continued to access data after they’d been fired.

Though the findings place the case squarely into the category of political cyber-crimes that have otherwise been high-profile priorities, the lead FBI agent assigned to the Awan case was a first-year agent, and not from one of the FBI’s big-guns divisions. The charges brought by prosecutors are so minor that Awan’s own lawyer speculated they could be a “placeholder” for future charges.

Server logs of government computers backed up the OIG’s findings. Yet six months after the initial charges, no additional counts have been brought, raising the question of whether the DOJ is seriously investigating the potential national security breach.

Read the whole article. It outlines in great detail how both the FBI and the Justice Department show no interest in prosecuting this case. The evidence is condemning, and it especially condemns Attorney General Jeff Sessions, which appears to have allowed the stonewalling to occur. Is he, and Trump, not legally in charge? Why have they sat on their hands and allowed this?

China test fires core engine for its Long March 5 rocket

On February 11 China did a static fire test of the core engine for its Long March 5 rocket, that country’s largest rocket that has been grounded since a launch failure in July 2017.

The YF-77 is China’s most powerful rocket engine, burning liquid hydrogen fuel and liquid oxygen oxidiser to provide 510 kN (110,000 lbf) of thrust at sea level. A pair of these engines power the core stage of the Long March 5.

The Long March 5 heavy-lift rocket successfully debuted in late 2016 but failed to reach orbit with its second flight, in July. Following an investigation into the launch failure, it has been announced that the next launch is being planned for the second half of 2018 from the specially built Wenchang Space Launch Centre on the island province of Hainan, at 19 degrees North. No causes of the failure, which some observers pin to an underperformance of the first stage brought on by an engine issue, have been publicly revealed, and thus no indication as to whether the issue was related to design or a manufacturing problem.

The Chinese continue to be very tight-lipped about the situation with the Long March 5. This static fire test suggests however that the issue was with the core engine.

Methane detected on Enceladus could come from microbes

The uncertainty of science: New research has found that the methane that Cassini detected being released from Enceladus’s interior could conceivably come from at least one Earth-type microbe.

Using various mixtures of gases held at a range of temperatures and pressures in enclosed chambers called “bioreactors,” Rittmann and his co-authors cultivated three microorganisms belonging to the oldest branch of Earth’s tree of life, known as Archaea. In particular, they focused on Archaean microbes that are also methanogens, which are able to live without oxygen and produce methane from that anaerobic metabolism. The team examined the simplest types of microbes, which could be the primary producers of methane at the base of a possibly more complex ecological food chain within the moon.

They tried to simulate the conditions that could exist within and around Enceladus’s hydrothermal vents, which are thought to resemble those found at a few deep-sea sites on Earth, often near volcanically active mid-oceanic ridges. According to their tests, only one candidate, the deep-sea microbe Methanothermococcus okinawensis, could grow there—even in the presence of compounds such as ammonia and carbon monoxide, which hinder the growth of other similar organisms.

There are a lot of fake news stories today trumpeting this result as proof that alien microbes can exist on Enceladus. The data does no such thing. All it shows that one methane producing microbe could possibly live in an environment that researchers guess might somewhat resemble the situation on Enceladus. However, as the article admits,

Scientists do not really know the precise conditions on Enceladus yet, of course. And in any case it is possible any life there, if it exists, is nothing like any DNA-based organism on our planet, rendering our Earth-based extrapolations moot. What’s more, these findings only show microbial life might exist in one particular subset of possible environments within the moon’s dark ocean.

This result is interesting, but it really proves nothing about Enceladus itself.

New backers to run Arecibo

The National Science Foundation this week revealed the make-up of the consortium that is taking over the operation of the Arecibo radio telescope in Puerto Rico.

The new agreement is valued at $20.15 million over five years, subject to the availability of funds, and is scheduled to begin April 1, according to the statement.

The new partnership represents a mixture of academic and corporate interests. The Universidad Metropolitana in San Juan, Puerto Rico, and Yang Enterprises Inc. in Oviedo, Florida, will partner with [the University of Central Florida] to manage the observatory. The team plans to expand the capabilities of the telescope, officials said.

This relieves the National Science Foundation (and the taxpayers) of the the cost burden for this facility, at least directly.

Interorbital completes static fire test of upper-stage engine

Capitalism in space: The smallsat rocket company Interorbital (IOS) today released a short video showing a successfully static fire test of the upper-stage engine for its Neptune rocket.

The IOS rocket team successfully completed the first test of Interorbital’s NEPTUNE series launch vehicle’s liquid upper-stage rocket engine (GPRE 0.75KNTA). Engine performance was well within its design parameters, generating a sea-level thrust of 750 pounds and a sea-level specific impulse of 245 seconds. This translates to a thrust of 1,000 pounds and a specific impulse of 300 seconds in a vacuum (with expansion nozzle). The ablatively-cooled rocket engine is powered by the hypergolic combination of White Fuming Nitric Acid (WFNA) and Turpentine/Furfuryl Alcohol. These high-density storable auto-igniting propellants power all IOS liquid rocket engines. Interorbital’s N1 launch vehicle utilizes two GPRE 0.75KNTA engines for its second stage and a single GPRE 0.75KNTA engine for its third stage.

I have embedded the video below the fold. This is the first real news update from Interorbital in months. In April 2017 they looked like they were close to a launch, but until today there were no further updates. Part of the issue appears that they changed their approach for manufacturing their rocket in order to save cost, and this might have thrown a wrench in their schedule.

George Nield of FAA space office is retiring

George Nield, who has been the associate administrator for Commercial Space Transportation at the Department of Transportation’s Federal Aviation Administration (FAA), is going to retire at the end of March.

Nield has held the position for the past 15 years, and has been a big supporter of private commercial space. While Congress has passed laws during this time period that gave his office lots of regulatory power and thus the ability to lord it over these new companies, Nield instead worked with them so that their efforts would not be hampered by the government. The result has been the birth of a thriving competitive and innovative private launch industry.

I fear what will happen with the next person to hold this position. History tells us that bureaucracies always expand their power with every opportunity, with such expansions often instigated by the arrival of new bureaucrats eager to take advantage of the regulations to build themselves an empire.

Hubble finds new figure for universe expansion rate

The uncertainty of science: Using data from the Hubble Space Telescope astronomers have found evidence that universe’s expansion rate is faster than estimated in previous measurements.

The new findings show that eight Cepheid variables in our Milky Way galaxy are up to 10 times farther away than any previously analyzed star of this kind. Those Cepheids are more challenging to measure than others because they reside between 6,000 and 12,000 light-years from Earth. To handle that distance, the researchers developed a new scanning technique that allowed the Hubble Space Telescope to periodically measure a star’s position at a rate of 1,000 times per minute, thus increasing the accuracy of the stars’ true brightness and distance, according to the statement.

The researchers compared their findings to earlier data from the European Space Agency’s (ESA) Planck satellite. During its four-year mission, the Planck satellite mapped leftover radiation from the Big Bang, also known as the cosmic microwave background. The Planck data revealed a Hubble constant between 67 and 69 kilometers per second per megaparsec. (A megaparsec is roughly 3 million light-years.)

However, the Planck data gives a constant about 9 percent lower than that of the new Hubble measurements, which estimate that the universe is expanding at 73 kilometers per second per megaparsec, therefore suggesting that galaxies are moving faster than expected, according to the statement.

“Both results have been tested multiple ways, so barring a series of unrelated mistakes, it is increasingly likely that this is not a bug but a feature of the universe,” Riess said. [emphasis mine]

I should point out that one of the first big results from Hubble in 1995 (which also happened to be the subject one of my early published stories), the estimate then for the Hubble constant was 80 kilometers per second per megaparsec. At the time, the astronomers who did the research were very certain they had it right. Others have theorized that the number could be as low as 30 kilometers per second per megaparsec.

What is important about this number is that it determines how long ago the Big Bang is thought to have occurred. Lower numbers mean it took place farther in the past. Higher numbers mean the universe is very young.

That scientists keep getting different results only suggests to me that they simply do not yet have enough data to lock the number down firmly.

Japan successfully launches reconnaissance satellite

Japan’s space agency JAXA today successfully launched a reconnaissance satellite for the Japanese government.

The Japan Aerospace Exploration Agency and Mitsubishi Heavy Industries, the H-2A rocket’s main contractor, did not provide a live video webcast of the mission. But news media and other spectators near the launch pad streamed the launch live online, and announcements over loudspeakers at the Tanegashima press site confirmed separation of the IGS Optical 6 satellite in orbit.

The spacecraft’s specifications, including its imaging performance, are kept secret by the Japanese government. But the government has acknowledged the satellite will join a fleet of Information Gathering Satellites operated by the Cabinet Satellite Intelligence Center, which reports directly to the Japanese government’s executive leadership.

The leaders in the 2018 launch standings:

7 China
4 SpaceX
3 Japan
2 ULA
2 Russia

There have been 21 launches in the first two months, continuing January’s pace that suggests we will see more than a hundred launches in 2018, the highest number since 1990.

Stratolaunch completes initial taxi tests

This past weekend Stratolaunch successfully completed its second series of taxi tests, reaching a speed of 40 knots (46 miles per hour) as it moved down the runway.

[I]n December Stratolaunch capped off the year with a successful low-speed taxi test. During the taxi, the vehicle reached a top speed of 28 miles per hour (45 kilometers per hour) as it headed down the runway. Following the test, Aircraft Program Manager George Brugg stated, “This was another exciting milestone for our team and the program. Our crew was able to demonstrate ground directional control with nose gear steering, and our brake systems were exercised successfully on the runway. Our first low-speed taxi test is a very important step toward first flight.”
