Privately built smallsat designed deep space communications

9:05 am

The competition heats up: A partnership between two British space companies, a smallsat manufacturer and a space antenna operator, will team up to build and test a new smallsat communications satellite in lunar orbit.

The SSTL-GES Lunar Pathfinder team are already working on the initial baseline design, with technical assistance from the European Space Agency (ESA). SSTL are designing a series of lunar communication satellites and will be building on their heritage of small satellite platforms in Low Earth orbit and Medium Earth orbit to go beyond Earth’s orbit for the first time. GES are upgrading one of the famous antennas at their Goonhilly site in Cornwall, UK, into a deep space ground asset, which will be the first element in a commercial deep space network. In addition, GES will provide a dedicated mission operations centre situated in Cornwall.

What is interesting about this is that this is a private effort to develop a modern commercial deep space communications network for future planetary missions. It would be competitive with NASA’s Deep Space Network, which presently is the only game in town and is generally made up of upgraded 1960s based technology. This new network would also eventually include a dedicated network of smallsats scattered through the solar system to act as communications relays. This is something that NASA does not provide, depending instead on the communications instruments of the planetary missions themselves.

ESA contract for hypersonic engine research

8:52 am

The competition heats up: The European Space Agency has signed a research contract for 10 million euros with Reaction Engines to build a ground-based prototype of its hypersonic rocket engine.

While ground testing is always necessary, I am not sure what they gain by building a solely ground-based prototype. Hypersonic engines use the oxygen in the atmosphere, much like jet engines. Their operation however is dependent on altitude as well as the speed in which they are traveling, neither of which is easily tested on the ground.

This project is also one part of the United Kingdom’s new space agency program.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

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

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

 

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

 

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

 

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

Rocket Lab gets new launch contract

11:17 pm

The competition heats up: Rocket Lab has signed a three launch contract with the smallsat Earth resources satellite company Planet (formerly Planet Labs).

The contract covers three dedicated launches of Dove satellites built by San Francisco-based Planet, formerly known as Planet Labs, on Electron vehicles. The companies did not announce terms of the deal, although Rocket Lab quotes a list price of $4.9 million per Electron launch on its website.

Mike Safyan, director of launch and regulatory affairs for Planet, said in an interview during the International Space Station Research and Development Conference here that the number of satellites that each launch will carry is still being determined, but will likely be between 20 and 25. Each Dove is a three-unit cubesat with a mass of about five kilograms.

If this report as well as previous ones are correct, the first Electron rocket launch will happen before the end of this year.

Toilet failure on U.S. segment of ISS

11:14 pm

According to this report, the American-built toilet on the U.S. part of ISS has broken down.

The story has few details, and is based on anonymous sources. Nonetheless, I suspect it is true, as the American toilet has had problems in the past, was originally designed for easy transport up and down from ISS on the space shuttle, and is thus difficult to repair in space.

Breakthrough on battery life?

6:50 pm

New research might have discovered engineering that could significantly increase the efficiency of the batteries we use.

This is where Mya Le Thai’s magic gel comes in. Typically, a Lithium Ion battery can go through between 5000 and 7000 recharge cycles before it dies and will also gradually lose its energy storage capacity over time. When researchers applied Thai’s plexiglass-like gel to gold nanowires in a manganese dioxiode shell, it increased that number to over 200,000 and the battery didn’t lose any of its power or storage capacity over a period of three months.

New Mexico insurance company abandoning Obamacare exchange

5:52 pm

Finding out what’s in it: A major New Mexico health insurance company has decided to stop selling individual insurance policies through the Obamacare exchange.

Apparently, people who got insurance through the exchange were generally sicker to begin with, and were poorer (80% required subsidies). The company decided the cost was too much.

Meanwhile, Obama has declared that the solution to this very bad government-run health care system is more government!

President Barack Obama, reviewing his signature health law six years into its implementation, is suggesting Congress and his White House successor add a government-run, or public, insurance option to the Affordable Care Act and increase federal financial assistance for people to buy coverage.

The problem with this proposal is this is exactly what the Obamacare exchanges were, except that the health insurance itself was provided by private companies. Obama is suggesting we expand the exchanges (which have failed miserably), but augment that failure with a system kind of like the Veterans Administration, where the government provides the healthcare. That should work just great, assuming we lived in a fantasyland invented by progressive leftists who pay no attention to reality.

But then, I think we do, considering how many people seem willing to vote for Hillary Clinton, a big supporter of Obamacare and a long time proponent of it.

Ban AC for DC

10:42 am

Link here. As Glenn Reynolds notes

I’m inspired by Rep. Lamar Smith, R-Tex., who noticed something peculiar recently. It seems that EPA Administrator Gina McCarthy, who spends a lot of time telling Americans that they need to drive less, fly less, and in general reduce their consumption of fossil fuels, also flies home to see her family in Boston “almost every weekend”; the head of the Clean Air Division, Janet McCabe, does the same, but she heads to Indianapolis. In air mileage alone, the Daily Caller News Foundation estimates that McCarthy surpasses the carbon footprint of an ordinary American. Smith has introduced a bill that wouldn’t target the EPA honchos’ personal travel, though: It provides, simply, that “None of the funds made available by this Act may be used to pay the cost of any officer or employee of the Environmental Protection Agency for official travel by airplane.”

This makes sense to me. We’re constantly told by the administration that “climate change” is a bigger threat than terrorism. And as even President Obama has noted, there’s a great power in setting an example: “We can’t drive our SUVs and eat as much as we want and keep our homes on 72 degrees at all times … and then just expect that other countries are going to say OK.”

Likewise, it’s hard to expect Americans to accept changes to their own lifestyles when the very people who are telling them that it’s a crisis aren’t acting like it’s a crisis. So I have a few suggestions to help bring home the importance of reduced carbon footprints at home and abroad:

Reynolds than goes on to suggest further restrictions on the fossil fuel use of the hoi poloi in Washington, including heavy taxes on fuel used by private jets, heavy taxes on coastal regions like liberal cities like New York, Boston, and Washington to prepare for sea rise, and the banning air-conditioning in the District of Columbia.

Obama makes a great point about setting the thermostat at 72 degrees. We should ban air conditioning in federal buildings. We won two world wars without air conditioning our federal employees. Nothing in their performance over the last 50 or 60 years suggests that A/C has improved things. Besides, The Washington Post informs us that A/C is sexist, and that Europeans think it’s stupid.

Makes sense to me!

Black racism and hate

9:07 am

Three stories today illustrate the growing hate, violence, and bigotry within the modern black power movement:

These are only a sample of the numerous similar stories in the past few years, most of which revolve around the generally racist Black Lives Matter movement, which only cares about black lives and gets very offended if you note that all lives matter. Consider for example the words of Babu Omowale, the “national minister of defense for the People’s New Black Panther Party” in the third link above:

We know that we are owed land, we are owed monies, we are owed restitutions and we are owed reparations.

In other words, blacks today must be rewarded and everyone else who is not black punished because of something that was done to someone else by someone else, a hundred years or more in the past. And the only reason blacks are owed reparations is because they are black, with everyone else who is not black guilty and therefore to be punished, even though no one today had anything to do with the past injustice of slavery.

While most blacks in America are ordinary people who don’t hate anyone and want to live their lives peaceably, the culture they live within is increasingly focused, like the New Black Panthers, on race and hate. That culture is also increasingly abandoning the ideals that made the civil rights movement a success and led to election of a black man as President of the United States, even though blacks comprise less than 15% of the American population.

The consequences of this will be exactly the opposite of what the Black Lives Matter movement and the New Black Panthers claim they want, a greater respect for blacks. Instead, these movements will isolate blacks and make them a target, an enemy to everyone else in the country. I can’t emphasize how mistaken and foolish this is. Unless the good people in the black community reject it soon and loudly, they — as well as everyone else — are going to suffer badly in future years because of it.

It never pays to view people by their race, ethnicity, or gender. What matters is what each person does. We are not races, ethnicities, or genders. We are each a human being, each with a soul and a potential to do good or evil. We should thus be judged as an individual. Everything else is irrelevant, and if you try to include it you are revealing yourself to be racist and a hate-monger.

Sierra Nevada completes first Dream Chaser milestone

7:56 am

The competition heats up: Even as it prepares to complete the last milestone in its NASA contract for developing a manned version of Dream Chaser, Sierra Nevada has just completed the first milestone on its contract to build a cargo version of the reusable lifting body spaceplane.

Though Sierra Nevada did not win a contract to build the manned Dream Chaser, it did have a development contract with NASA that called for one more glide flight test, a test the company had until now decided not to fly because the cost would exceed the milestone payment. This changed however after they won a cargo contract, as the flight will provide important test data for building the cargo version.

Meanwhile, the company’s plan for building the cargo vehicle has been approved by NASA, thus rewarding them their first milestone on that contract, with the following schedule:

Per current schedule goals, Mr. Olson added the inaugural Dream Chaser cargo flight to ISS is aiming for a launch – on the United Launch Alliance Atlas V – as early as October 2019, or as late as April 2020. The company is aiming to build two Dream Chasers, able to fly a total of 30 times over a 10 year lifetime.

Once built and successfully flying, they also plan to move forward on developing the manned version, both for NASA and for others.

Vision problems from weightlessness

6:03 pm

This article provides an excellent review of the vision problems caused by long term exposure to weightlessness, including the efforts to study the problem on Earth.

Bottom line:

Before a human trip to Mars — a journey of six-to-nine months that NASA says it wants to achieve by the 2030s — researchers agree that VIIP [the name given to this problem] must be understood much better. VIIP could be the first sign of greater dangers to the human body from microgravity. “We’re seeing the visual and neural, ophthalmic manifestations of it,” Barratt said. “I’m fairly certain this is a bit more global than that.”

Richard Williams, the chief health and medical officer at NASA, agrees that what we do not know about VIIP still poses the biggest threat. Ironically, one of the only ways to get more knowledge is spend more time in microgravity. “The longer we stay in space, the more we’re going to learn,” Williams said.

Getting and Installing Linux – Part 3

6:01 am

UEFI and booting Linux on Win 8.1 & 10 machines

by James Stephens

Unified Extensible Firmware Interface (UEFI) is intended to be a modern alternative to BIOS. Ideally UEFI-(Secure Boot) blocks malware from being loaded when the computer is booted by using digital keys which software must possess in order to be booted onto the computer. UEFI supplants the traditional BIOS and it’s post screen, appreciably shortening boot times but sometimes adding a few more steps to set up a computer to boot into Linux. If necessary UEFI-(Secure Boot) may be disabled to allow access to the BIOS and the booting of non-UEFI complaint operating systems, such as 32 bit Linux or legacy Windows, and set up the computer to boot into Linux as I described in the previous post. But I recommend using UEFI if at all possible.

Another Obamacare co-op folds

12:41 am

Finding out what’s in it: Another Obamacare co-op folded today, the second to do so this week and the 15th out of the original 23 to fail.

Oregon’s Department of Consumer and Business Services (DCBS) announced Friday that it is taking over the insurer, known as Oregon’s Health CO-OP, and will liquidate the company. The plan’s 20,600 enrollees will be forced to find new health insurance, with their plans ending on July 31. The state will hold a special sign-up period to allow these enrollees to find new coverage.

Do not be surprised if most if not all of the remaining 8 co-ops also shut down in the next year. Do not be surprised if we also see the failures of several private for-profit insurance companies as well.

Too bad no one predicted these failures, except for every Republican in Congress as well as conservatives and tea party activists across the country.

Two anti-fracking/anti-oil industry environmental papers retracted

11:40 pm

Thank goodness these were peer reviewed! Two environmental papers, one claiming increased air pollution near fracking sites and the second claiming that the 2010 Gulf of Mexico oil spill caused air contamination, have now both been retracted because of “crucial mistakes.”

According to the corresponding author of both papers, Kim Anderson at Oregon State University, the journal plans to publish new versions of both papers in the next few days. In the case of the fracking paper, the conclusions have been reversed — the original paper stated pollution levels exceeded limits set by the U.S. Environmental Protection Agency (EPA) for lifetime cancer risk, but the corrected data set the risks below EPA levels.

The fracking paper received some media attention when it was released, as it tapped into long-standing concerns about the environmental dangers of hydraulic fracturing (fracking), which extracts natural gas from the earth. A press release that accompanied the paper quoted Anderson as warning: “Air pollution from fracking operations may pose an under-recognized health hazard to people living near them.”

Both papers, published in Environmental Science and Technology, were retracted on the same day (June 29), both due to mistakes in reported levels of polycyclic aromatic hydrocarbons (PAHs), pollutants released from burning oil, gas, and other organic matter.

They say that the errors were due to an “honest spreadsheet error.”

TMT likely to abandon Hawaii

3:55 pm

Officials from the consortium that is building the Thirty Meter Telescope (TMT) have revealed that they are looking very seriously at alternative locations.

Officials behind the proposed Thirty Meter Telescope (TMT) are considering new locations for the $1.4bn facility, and expect to decide whether to opt for a new site early next year. The TMT is due to be built on Hawaii’s Mauna Kea mountain but, following protests from local residents, its building permit was revoked last December by the state’s Supreme Court. New locations that are being considered include Baja California in Mexico, the Canary Islands and Chile, as well as locations in India and China.

They claim that Hawaii is still their first choice, but if they don’t see any progress by summer in the permitting process, I expect them to tell Hawaii to go to hell (though not in those words) and pick somewhere else.

New Navy communications satellite in trouble

3:46 pm

A Navy communications satellite launched two weeks ago by a ULA Atlas 5 rocket is having trouble reaching its planned geosynchronous orbit.

From that highly elliptical preliminary orbit, the Lockheed Martin-built satellite would perform 7 firings of its Liquid Apogee Engine to raise the low point to circularize the orbit and reduce its orbital tilt closer to the equator.

But after an unspecified number of burns were completed, the trip to geosynchronous orbit was stopped, the Navy said in response to questions submitted by Spaceflight Now. “The satellite experienced an anomaly that required the transfer maneuver to be temporarily halted,” the Navy says. “The Navy’s Program Executive Office for Space Systems has reconfigured the satellite from orbital transfer into a stabilized, safe intermediate orbit to allow the MUOS team to evaluate the situation and determine options for proceeding.”

A blunt honest appraisal of America today

12:32 pm

The coming dark age: This op-ed encapsulates perfectly my despairing sense of today’s American culture, and what it will bring to the future.

After noting the effort by Obama and the Democrats these past eight years to divide Americans by race, party, gender, religion, and creed, he then adds:

Into this, Republicans are responding not with a candidate who will rise above the fray and try to unite us all back into common culture, but a man with no temperament to do anything other than divide. His loudest supporters embrace a “convert or die” mentality. We are either with him or against him.

Republicans have embraced a man who takes tribalism to new levels and, in the process, have put on blinders and willfully ignored how much he excites white nationalists and the race baiters of the right. For every New Black Panther in love with Barack Obama there are two white nationalists willing to march through hell for Donald Trump.

In his conclusion he adds

I’m afraid 2016 is the beginning of a chaotic time and not a one off occasion. We may look back on 2016 as the calm before the storm. What is most galling to me is that my party, the party I once served as an elected official, has turned to a man who has no intention of uniting the nation, who brings out the worst in absolutely everybody, and with so much on the line has so little a chance of even winning. But to point this out is to be accused of being a traitor and helping a woman I find equally offensive.

All of this is to say we get the government and national character that reflects us and right now it is all a damning indictment of our American character. How many more will die? How many more Americans will turn against each other? How many will seek blame instead of reconciliation?

Meanwhile, I am reminded of how, during the primary campaign, Ted Cruz was always willing to graciously reach out to protesters and debate the issues with them politely, face-to-face. That behavior, in modern America, has now been called “creepy” and the act of a liar.

We get the government we deserve. Be prepared for bad things in the future.

The terrorist murders in Dallas

10:41 am

Last night, during a Black Lives Matter protest, five policeman were killed and nine people (seven cops) were wounded by rooftop sniper fire. One shooter was killed, after police learned that “he wanted to kill white people, especially white officers.”

This was clearly a terrorist attack, aimed very specifically at the police. It was clearly inspired and instigated by the hate being expressed during this election year by leftists and by the very bigoted Black Lives Matter movement, which really only cares about black people, and gets offended if you try to tell them that all lives matter.

Five years ago shortly after the Tucson shootings that badly injured Congresswoman Gabby Giffords, I noted in disgust the inflammatory language of the left. Even as they were demanding more civility from conservatives, they were also demanding the murder of conservatives. At that time I called on them to tone down their rhetoric.

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?”

Sadly, in the five years since I have seen no effort at all by the left to tone down its rhetoric. If anything, they have notched it up, repeatedly expressing hate against conservatives and calling for increased acts of violence and oppression against them. Thus, we should not be surprised by last night’s attacks in Dallas. Nor should be be surprised if it gets worse in the coming months, as we get closer to the election. While the right wants to win in the voting booth, too many people on the left now seem to consider the idea of elections inconvenient and a problem, and also consider violence as a reasonable response should they lose at the polls.

Permanently shadowed regions on Ceres

9:53 am

Using data from Dawn scientists have calculated that Ceres could have significant regions on the floors of crater, which are permanently shadowed and which could accumulate water ice.

In this study, Schorghofer and colleagues studied Ceres’ northern hemisphere, which was better illuminated than the south. Images from Dawn’s cameras were combined to yield the dwarf planet’s shape, showing craters, plains and other features in three dimensions. Using this input, a sophisticated computer model developed at NASA’s Goddard Space Flight Center, Greenbelt, Maryland, was used to determine which areas receive direct sunlight, how much solar radiation reaches the surface, and how the conditions change over the course of a year on Ceres.

The researchers found dozens of sizeable permanently shadowed regions across the northern hemisphere. The largest one is inside a 10-mile-wide (16-kilometer) crater located less than 40 miles (65 kilometers) from the north pole. Taken together, Ceres’ permanently shadowed regions occupy about 695 square miles (1,800 square kilometers). This is a small fraction of the landscape — much less than 1 percent of the surface area of the northern hemisphere.

Because Ceres is much farther than the Sun that the Moon or Mercury, the scientists believe it very likely that water ice could have accumulated in these cold traps.

MRI software bug invalidates 40,000 research papers

9:33 am

The uncertainty of science: A bug just discovered in the computer software used by MRIs to measure brain activity could invalidate 15 years of research and 40,000 science papers.

They tested the three most popular fMRI software packages for fMRI analysis – SPM, FSL, and AFNI – and while they shouldn’t have found much difference across the groups, the software resulted in false-positive rates of up to 70 percent. And that’s a problem, because as Kate Lunau at Motherboard points out, not only did the team expect to see an average false positive rate of just 5 percent, it also suggests that some results were so inaccurate, they could be indicating brain activity where there was none.

“These results question the validity of some 40,000 fMRI studies and may have a large impact on the interpretation of neuroimaging results,” the team writes in PNAS. The bad news here is that one of the bugs the team identified has been in the system for the past 15 years, which explains why so many papers could now be affected. [emphasis mine]

The research the article described is focused entirely on the problems the software causes for past research. It makes no mention of the problems this software bug might cause for actual medical diagnosis Was the treatment of any patients effected by this bug? It does not say.

A description of SLS’s first launch

9:18 am

This article provides a detailed look at the planned 2018 first launch of SLS, describing step-by-step the launch process that will send an unmanned Orion capsule toward the Moon.

As my readers know, I am not a fan of SLS. I consider it an incredible waste of money that will never accomplish anything. Nonetheless, that first launch will be a cool thing to watch, as the rocket will generate comparable energy as the Saturn 5.
