Near the Martian shoreline
One of the prime areas of research for Mars planetary geologists is the region on Mars where the geography appears to transition from the southern cratered, rough terrain to the northern low, generally smooth, and flat plains. It is theorized by some scientists that the northern plains were once an ocean, probably shallow and probably intermittent, but wet nonetheless for considerable periods. The global map of Mars below, created by the laser altimeter on Mars Global Surveyor, clearly shows the obvious elevation differences between the low northern plans (blue) and the high, more cratered southern regions (changing from yellow to orange as you move higher).
Scientists have spent a considerable effort studying this transition zone (green on the map), illustrated by just one example I recently highlighted, showing that, though there does not appear to be a clear shoreline in many places, there is strong evidence that a shallow ocean repeatedly rose and fell in this transition zone, leaving behind geological ripple marks vaguely reminiscent of those seen on a beach caused by the rise and fall of the tides.
Today we highlight another example, taken in January 2018 at the location indicated by the cross on the above map.

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
Google and Amazon patent 1984-style devices that spy on you in your home
Another reason to dump these companies: Google and Amazon have both patented devices that are designed to spy on you at all times in your home.
The description of Google’s devices is particularly vile, and almost matches precisely the spying devices George Orwell created in 1984 that allowed the government to monitor its citizens 24 hours a day.
Google’s patent application outlines how audio and visual signals could be used to better understand a speaker’s mood or medical condition, according to the New York Times. The devices could listen to the ‘volume of the user’s voice, detected breathing rate, crying’. They could also detect a user’s coughing and sneezing.
The same patent applications reveals a device that could ‘recognize a T-shirt on a floor of the user’s closet’ with Will Smith’s face. It could then combine this with a browser history that shows searches for Mr Smith. This would allow Google to ‘provide a movie recommendation that displays, ‘You seem to like Will Smith. His new movie is playing in a theatre near you.’
In a separate patent application, Google describes a device that would give advice to parents for ‘areas of improvement’ such as spending more time with their children at supper. When children are near a drinks cabinet or are in their parents’ bedroom alone, the system may infer that mischief is likely to be occurring’, the patent read. On detecting mischievous behaviour, the smart device could even hand out punishments such as restricting mobile phone use.
Both Google and Amazon have made it clear in the past year that they are are increasingly partisan, strongly leftist with agendas favoring the Democratic Party. You therefore have to be a simpleton to think that this information will never be used by them for political reasons someday.

44 Democrats waived background checks for Imran Awan
Every Democrat in the House who hired Pakistani Imran Awan to run their computers, 44 in total, also exempted him from the required background checks.
All of them appear to have waived background checks on Imran Awan and his family members, even though the family of server administrators could collectively read all the emails and files of 1 in 5 House Democrats, and despite background checks being recommended for such positions, according to an inspector general’s report. The House security policy requires offices to fill out a form attesting that they’ve initiated background checks, but it also includes a loophole allowing them to simply say that another member vouched for them.
Among the red flags in Abid’s background were a $1.1 million bankruptcy; six lawsuits against him or a company he owned; and at least three misdemeanor convictions including for DUI and driving on a suspended license, according to Virginia court records. Public court records show that Imran and Abid operated a car dealership referred to as CIA that took $100,000 from an Iraqi government official who is a fugitive from U.S. authorities. Numerous members of the family were tied to cryptic LLCs such as New Dawn 2001, operated out of Imran’s residence, Virginia corporation records show. Imran was the subject of repeated calls to police by multiple women and had multiple misdemeanor convictions for driving offenses, according to court records.
This story is particularly disturbing. Either all 44 Democrats were incredibly stupid, or they actually wanted Awan capable of passing classified information to his sources in Pakistan. Either way, everyone of these Democrats is culpable, and if the latter is true, they are also traitors.

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 the Mars Society.

Tiangong-1 reentry window narrowed to only 3.4 hours and two orbits
The sky is falling! The Tiangong-1 reentry window has now been narrowed to only 3.4 hours and two orbits, centered on 8:30 pm (Eastern) on April 1.
It appears the world might be dodging this very minor bullet. The new window, which the spacecraft has just now entered as I write this, has allowed for the first prediction on where it should come down, and it appears that this will be in the southern hemisphere in the Pacific west of South America.
Update: Tiangong-1 came down in the Pacific Ocean at 8:15 pm (Eastern) on April 1.

Contact with Indian military communications satellite lost
Despite its successful launch earlier this week, India has lost contact with the military communications satellite.
They think the failure was due to a loss of power, that this remains unconfirmed.

Tiangong-1 now expected to reenter on April 2
New calculations of Tiangong-1’s orbit now suggest that it will reenter the atmosphere on April 2 ten minutes after midnight, give or take two and a half hours either way.
It appears that earlier calculations had expected more solar activity to push on the station. Instead, the activity was far less, so that the station will stay in orbit about a half day longer.

SpaceX ship returns with this week’s fairing apparently intact
Despite tweets from Elon Musk suggesting it had hit the water at “high speed,” SpaceX’s recovery ship appears to have returned with one half of the fairing intact.
There are several images at the link showing the fairing on the ship. That it recovered it out of the water without damage seems surprising and unlikely. Nonetheless, that it looks intact means that the parafoil managed to slow it down enough to limit damage as it hit the water, and the company seems to be making real progress towards making these fairings reusable.

Another successful launch for China today
China successfully completed its tenth launch for 2018 today, placing three Landsat-type Earth observation satellites into orbit with its Long March 4C rocket.
The leaders in the 2018 launch standings:
10 China
6 SpaceX
4 Russia
3 Japan
3 ULA
There have now been 29 launches in the year’s first three months, suggesting a pace that will give us about 120 launches total for the year, the most launches since the 1980s. Then, the Soviet Union was putting up a lot of rockets it could not afford and were not really practical. Now, we have some real competition and profits being made putting up satellites that fill a need. The numbers should only get higher in the coming years.

A detailed look at Orbital ATK’s Next Generation Launcher (NGL)
Link here. Based on the solid rocket technology developed for the shuttle and then for Ares, they hope to make the first launch in 2021, and actually do two flights that year to get certified by the Air Force so that they can bid on military launch contracts.
Development money for this rocket has come mostly from the Air Force, not from private funds raised by Orbital ATK. It also seems to me that it has taken far longer to get it built than it should if they really wanted to get a rocket up and running to compete for business. Moreover, they expect the Air Force to certify them after only two launches, while it took SpaceX a lawsuit and far more launches to get the same certification.
Thus, all told there is a bit of crony capitalism involved here. NGL might turn out to be a good deal, in the long run, but forgive me if I reserve my opinion.

Tiangong-1 reentry update
Aerospace Corporation has now narrowed the reentry window for China’s out-of-control Tiangong-1 station to 18 hours, centered at 12:15 pm (Eastern) on April 1st.
In my previous update I had misread their prediction, cutting the window in half by mistake. This new window means the spacecraft is predicted to come down anytime between 3:15 am (Eastern) and 9:15 pm (Eastern) on April 1st.

NOAA bureaucracy shuts down SpaceX telecast because stupid
Government marches on! The NOAA bureaucracy forced SpaceX to shut down its launch telecast this morning because agency bureaucrats had decided that views of Earth in the background were the equivalent of a satellite remote sensing system that the agency is required to regulate.
It was definitely an issue with NOAA, the rocket company said. Apparently NOAA recently asserted that cameras on the second stage of the Falcon 9 rocket, which SpaceX uses for engineering purposes, qualify as a remote sensing system, which are subject to NOAA’s regulation. A provisional license obtained by SpaceX for Friday’s launch of the Iridium-5 mission required it to end views once the second stage reached orbit.
This raises some questions about the real purpose behind NOAA’s action, as the regulation specifically exempts “small, hand-held cameras.” SpaceX intends to obtain a full license for such camera views, and as of now there is apparently no restriction in place for SpaceX’s next launch of a NASA cargo ship from Florida, happening as early as Monday.
One theory put forth is that some bureaucrats at NOAA might not have liked the good press that SpaceX got when it broadcast views of the Tesla in space, launched by the Falcon Heavy, and wanted to exert their petty power. This might not be true. What is true is that this interference by NOAA in SpaceX operations is beyond stupid.
But then, why should be expect anything different from our present federal government?

Trump Justice Dept decides to defend IRS harassment of conservatives
Still working for the Democratic Party: In a new twist, the Trump Justice Department has decided to backtrack from a settlement with one conservative group, True the Vote, that had been harassed aggressively not only by the IRS but by the FBI, Justice, OSHA, ATF, and numerous other agencies that during the Obama administration suddenly instituted 23 audits against them.
By the beginning of 2018, the DOJ appeared ready to strike a deal. The IRS agreed to a laundry list of wrongdoing, legal protection from further abuse, and they would allow True the Vote to petition for attorney fees for the years this mess was tied up in courts. Engelbrecht and True the Vote agreed and signed the decree. Now, though, the happy headlines have faded and the DOJ has reversed the course and filed a response to the court opposing the True the Vote petition. DOJ denies admitting to anything, stated the consent decree shows that conservative groups had, in fact, lost in court and that in their view the IRS had won. The settlements meant nothing, and not one dime of attorney fees would be awarded.
DOJ now claims that the IRS was right to fight True the Vote. Engelbrecht notes, “The Trump administration is defending the IRS targeting American citizens.” It’s like the Obama DOJ is back in the saddle. True the Vote’s battle continues.
The short embedded video from True the Vote below the fold summarizes the situation, and illustrates that the Trump administration appears no different than the Obama administration. No house cleaning has taken place, and it appears that no house cleaning is planned. The abuse of citizens by these agencies continues.

ESA successfully completes first parachute test for 2020 ExoMars mission
Early in March the European Space Agency successfully completed the first of a series of parachute tests for its 2020 ExoMars rover mission.
The focus of the latest test, conducted in sub-zero conditions in Kiruna, Sweden earlier this month, was the 35 m-diameter second main parachute. The test demonstrated the deployment and inflation of the parachute with its 112 lines connected to a drop test vehicle, via the deployment of a smaller 4.8 m-wide pilot chute.
This test only tested the parachutes deployment system. They still need to do this test at high altitudes to duplicate Mars’ conditions using high-altitude balloons.
When ExoMars reaches Mars, the parachute will act to slow the spacecraft down during descent. For the actual landing, they will be using systems designed and built by the Russians.

FCC approves SpaceX 4K+ satellite constellation with strict new requirements
Capitalism in space: The FCC today approved SpaceX proposed gigantic 4,425 Starlink satellite constellation, designed to provide internet access worldwide, while also imposing a deadline for its launch and requiring the company to provide detailed de-orbit plans.
SpaceX will have to launch at least half of its constellation of Ku- and Ka-band satellites within six years of today, per the agency’s recently revised rules, or its authorization freezes at the number of satellites in operation at that date. The FCC in September relaxed its deadline, giving operators nine years to launch their full constellation, but even those rules are stricter than what SpaceX would refer. The launch-provider-turned-satellite operator asked the FCC for an okay to launch 1,600 satellites in six years — just over a third of its full constellation.
SpaceX said the FCC’s deadline was “impractical” and that it could start broadband service without the full constellation. The FCC said no, but gave SpaceX permission to re-submit a waiver request in the future. SpaceX said in October it plans to start service with 800 to 900 satellites.
SpaceX’s constellation is the largest of all the applicants, generating concern about its potential to enshroud the Earth in a cloud of space debris. Fleet operators OneWeb, Spire, SES and Space Norway all expressed concern about how SpaceX will protect the space environment when operating so many satellites. But weighing more heavily with the FCC was NASA, which said a constellation as large as SpaceX’s likely needs to meet more stringent standards than what NASA recommends for de-orbit reliability. NASA’s reliability standard is that at least 90 percent of satellites can deorbit properly after their mission is complete.
The FCC did say that SpaceX will have the right in the future to request a waiver on the launch deadline.

Blue Origin changes engines for New Glenn second stage
Capitalism in space: In order to maintain its goal of launch its orbital New Glenn rocket by 2020, Blue Origin has changed the engine it will use in the rocket’s second stage from a version of its main BE-4 engine to new version of their already developed BE-3 engine, used in their reusable New Shepard suborbital spacecraft.
A Blue Origin executive told SpaceNews the company is shelving development of a vacuum-optimized version of BE-4 and will instead use vacuum-optimized versions of flight-proven BE-3 engines for New Glenn’s second stage and optional third stage. “We’ve already flown BE-3s, and we were already in the development program for BE-3U as the third stage for New Glenn,” said Clay Mowry, Blue Origin’s vice president of sales, marketing and customer experience. “It made a lot of sense for us to switch to an architecture where we get there faster for first flight.”
The BE-3U is the upper stage variant of the liquid hydrogen-fueled BE-3 engine that has powered Blue Origin’s reusable New Shepard spacecraft on seven suborbital test flights since its 2015 debut. Mowry said switching to the BE-3U for New Glenn’s second stage will allow Blue Origin to conduct the rocket’s first launch in the fourth quarter of 2020. He declined to say how much time the engine change saves compared to the original configuration.
This quiet change, which the company made with no fanfare, carries with it some significant information as well as important ramifications. First, the BE-3 engine is less powerful than the planned BE-4, which is why they will use two BE-3 engines in the second stage instead of one BE-4, while also extending the length of the stage to accommodate more fuel. Though they claim the change will increase the rocket’s range, I suspect however that even with these changes New Glenn’s overall orbital payload capacity will be reduced.
Second, the change indicates that development of the BE-4 engine is proceeding slower than expected, threatening their 2020 launch goal. They have had one test failure that set them back, and the change suggests to me that they are having issues with making the engine restartable.
Third, if they have problems making the BE-4 engines restartable, this means their plans to reuse the first stage of New Glenn will be impacted. While those first stage engines do not need to restart on any single flight, reusing them requires this capability.
Fourth, problems with the BE-4 might cause ULA to reject it and choose Aerojet Rocketdyne’s AR-1 engine for its new Vulcan rocket. Up to now ULA has indicated it prefers the BE-4. These issues might change that.
Fifth, this change, combined with the continuing lack of New Shepard test flights, suggests that the company is increasingly considering abandoning this suborbital spacecraft.
I am doing a lot of speculating here, and could be very wrong on many if not all of these suppositions. We shall have to wait and see.

Third, if they have problems making the BE-4 engines restartable, this means their plans to reuse the first stage of New Glenn will be impacted. While those first stage engines do not need to restart on any single flight, reusing them requires this capability.
Fourth, problems with the BE-4 might cause ULA to reject it and choose Aerojet Rocketdyne’s AR-1 engine for its new Vulcan rocket. Up to now ULA has indicated it prefers the BE-4. These issues might change that.
Fifth, this change, combined with the continuing lack of New Shepard test flights, suggests that the company is increasingly considering abandoning this suborbital spacecraft.
I am doing a lot of speculating here, and could be very wrong on many if not all of these suppositions. We shall have to wait and see.
World View launches first balloon flight since explosion, raises $26.5 million
Capitalism in space: World View today launched its first Stratollite balloon flight since one exploded on December 19 as it was being prepared for launch.
The flight was commissioned by the NASA Flight Opportunities program office for two principal customers, the NASA Ames Research Center and Space Environment Technologies, both of which are studying radiation detection and its energy levels at different altitudes. The balloon vehicle is expected to gather data and stay aloft for less than 24 hours, depending on winds and landing conditions, a World View spokesman said.
More important, the company announced that it had raised $26.5 million in investment capital. All told, it is estimated that the company has raised $48.5 million in three rounds of fund-raising.

SpaceX successfully launches ten Iridium satellites into orbit
Capitalism in space: SpaceX this morning successfully placed ten Iridium satellites into orbit using its Falcon 9 rocket.
They did maneuver and landing tests with the first stage, which was making its second flight, but did not try to recover it. They did attempt to catch one half of the rocket’s fairing with their fast-moving ship and its giant net. No word yet on whether that attempt worked. Fairing recovery failed. See comments below.
The leaders in the 2018 launch standings:
9 China
6 SpaceX
4 Russia
3 Japan
3 ULA
2 Europe
2 India
The U.S. and China remain tied at nine for the lead in the national rankings.

The massive data Facebook and Google collect on their users
Link here. The article is frightening, and illustrates once again why I have nothing to do with Facebook, and as little to do with Google as I can. (I wish someone would come up with a competitor to youtube. There’s money to be made there!)
What was especially disturbing was this tidbit about Google that the author discovered:
This is my Google Drive, which includes files I explicitly deleted including my résumé, my monthly budget, and all the code, files and websites I’ve ever made, and even my PGP private key, which I deleted, that I use to encrypt emails. [emphasis in original]
In other words, if you use Google to store any documents, no matter how private, they keep those documents even if you decide to delete them. Or to put it another way, Google steals them. Worse, the author also found that Google was keeping every email he’d ever sent or been sent to him, “including the ones [he] deleted or were categorised as spam.” [emphasis mine]
These corporations have compiled databases that can be misused very easily, and I expect someone in their company to do so, repeatedly. Worse, their users seem oblivious to the personal vulnerability that these databases create, and continue to nonchalantly use both Google and Facebook without thought.
I recognize that both companies provide services and need to make money by doing so. I just think they have overstepped the bounds of morality in how they compile and use the information they obtain.

Sessions names US attorney to investigate FISA abuses
Attorney General Jeff Sessions today informed Congress that he has tasked United States Attorney John W. Huber, based in Utah, to investigate the possible misuse of the FISA court by the Obama administration, the Justice Department, and the FBI during and after the presidential campaign.
From Sessions’ letter to Congress:
Mr. Huber is conducting his work from outside the Washington, DC. area and in cooperation with the Inspector General. …I am confident that Mr. Huber’s review will include a full, complete, and objective evaluation of these matters in a manner that is consistent with the law and the facts.
I receive regular updates from Mr. Huber and upon the conclusion of his review, will receive his recommendations as to whether any matters not currently under investigation should be opened, whether any matters currently under investigation require further resources, or whether any matters merit the appointment of a Special Counsel.
Huber is an Obama appointee, but appears to have avoided participating in partisan games. This will make it harder for Democrats to blast him should he recommend a special prosecutor is necessary. Meanwhile, some Republicans are complaining about Sessions’ decision to hold off appointing a special prosecutor, but I think this decision is smart. Huber will be under Sessions’ supervision and command. A special counsel would be uncontrollable (witness Mueller and every past special prosecutor). Considering the corrupt culture that now permeates Washington, keeping some control over this investigation to me seems wise.

Further launch delays for Russia’s next ISS module & space telescope
The race to be last! Russia today announced that the launch of both its next ISS module as well as a new space telescope will be delayed until 2019.
The ISS module, Nauka, is years behind schedule, and is presently being cleaned of contamination in its fuel system that was found several years ago.
“Repairs of the MLM Nauka are taking longer than expected, and the deadlines are yet unclear. This means it will not be brought to Baikonur any time soon, and the launch will be postponed until 2019,” the source said.
It was reported earlier that the mission would be delayed for six months. “The delivery of the MLM Nauka to the Baikonur cosmodrome has been moved from September to late 2018. Hence, the module’s launch to the ISS has been provisionally delayed for another six months,” the source said. The launch was scheduled for September 2018 with the possible alternative date in March 2019.
The article also notes delays for Spekr-RG high-energy space telescope until 2019. The article might also describe delays for another satellite, though the writing is unclear.
Nauka was first built in the 1990s as a backup for ISS’s first module. In the early 2000s Russia decided to reconfigure it and fly it to ISS, with its launch scheduled for 2007. This means its launch is now going to be twelve years behind schedule.
It sure does appear that Russia’s Roscosmos is competing with NASA to see which government agency can delay its missions the longest. In fact, for fun, let’s put together the standings!
- Nauka: 12 years behind schedule (originally scheduled for 2007, now 2019)
- James Webb Space Telescope: 9 years behind schedule (originally scheduled for 2011, now 2020)
- SLS/Orion: 8 years behind schedule (originally scheduled for 2015, now 2023)
Stay tuned. This race to the bottom is far from over. NASA could still win, especially because it has more than one project in the running.

India’s GSLV rocket successfully launches military communications satellite
India today successfully launched a military communications satellite using the Mark II version of its large GSLV rocket, the rocket’s fourth successful launch in a row.
Using a combination of liquid and solid-fuelled stages, the GSLV was designed to place communications satellites into geosynchronous transfer orbits. To this end, GSLV has increased performance over the smaller Polar Satellite Launch Vehicle (PSLV), from which it is derived.
GSLV’s first stage consists of a solid-fuelled core, with four radially-mounted liquid-fuelled strap-ons. The strap-ons are part of the first stage, and do not separate from the core. GSLV’s second stage, which is closely related to PSLV’s second stage, burns hypergolic liquid propellants, while the rocket’s third stage uses cryogenic fuel.
…The Mark II, which has a stretched third stage with an Indian engine, first flew in April 2010 but its new engine failed to ignite. The first successful Mk.II launch took place in January 2014. India also has a GSLV Mk.III. However, this is a completely new rocket that reached orbit for the first time last year. Excluding the Mk.III, Thursday’s launch was GSLV’s twelfth flight. In its previous eleven launches, GSLV has recorded six successes, four failures and one partial failure….GSLV’s current run of four consecutive successful launches is the longest that the rocket has achieved.
The leaders in the 2018 launch standings:
8 China
5 SpaceX
3 Japan
3 ULA
3 Russia
2 Europe
2 India
Both Russia and China have scheduled launches for today, with SpaceX having a launch scheduled for tomorrow, so expect these standings to be updated a lot in the next 24 hours.

Tiangong-1 re-entry window narrowed further
New calculations have narrowed the reentry window for Tiangong-1 to sixteen thirty-six hours, centered at 6:30 am (Eastern) on April 1.
This means reentry could come anytime during the 11 or so orbits from 10:30 pm (Eastern) on Saturday March 31 to 4:30 pm (Eastern) on Sunday April 1.
This post was incorrect, as the estimate was really 32 hours centered on 6:30 am (Eastern on April 1st, not 16. See my more recent post with an update.

March 27, 2018 Zimmerman/Batchelor podcast
Embedded below the fold in two parts. The first part of this podcast is definitely worth listening to. I go after NASA for both SLS and Webb, which seem to be projects in a competition to see who can last the longest without accomplishing anything. Both are now creeping towards project length’s exceeding two decades, and neither is close to flying.
